Abstract: Slotted saw blades are shown with wide slots in which hardface inserts extend below the bottoms of the slots and interlock with the core, extend above the periphery of the core, and extend at a negative hook angle for the direction of core rotation. In various embodiments, the inserts, which are bonded to the core, include elements that are integral portions of the cutting segments, elements arranged in each slot so that one is at the negative hook angle for one direction of core rotation and the other is at the negative hook angle for the opposite direction of core rotation, and wedge shaped elements.

Abstract: For inserts in boxes of bottled and canned goods, there is disclosed pad forming apparatus in which rotary dies are adapted to remove the edge portions of a roll or sheet of material, e.g., chipboard, as the roll is fed towards a rotary knife from feed rollers, the feeds being selected to determine the lengths of the pads for a given run, and the speeds of the rotary dies and knife being selected to effect material removal and cutting to insure that the pads of the selected length have rounded corners. The die parts are on rollers between which the material moves from the feed rollers, and are positioned so the edges of the material pass between them. Each die set has a punch on one roller and a slug shedder or ejector on an opposing roller, the shedder being spring biased and radially movable. The dies punch out cusp cutouts, and the knife cuts the material along lines through the midportions of the die cuts. As the dies separate, the shedders are released to eject the slugs of removed material.

Abstract: There is disclosed a system incorporating aligned cylinders through which a cable is moved. The cylinders have jet nozzles connected to respective manifolds which are adapted for receiving different fluids for treating the cable. Control apparatus is provided for operating the cylinder stages simultaneously, and permitting manual selection of any one or combination of such operations. With fluid applied to all nozzles simultaneously, the cable is successively blast cleaned with water, jet dried with air, and jet lubricated with oil. Also shown is control apparatus adapted to control a motor for moving the cable through the cylinders. The air drying station includes nozzles for moving the air tangentially and from the exit to the entrance end of the air cylinder, for drying the cable and preventing water from the cleaning station from entering the drying station.

Abstract: Various forms of tools are disclosed for effecting reciprocal movements between jaw members to be located between and exerting opposing thrusts on the flange and bolt head of a hollow wall anchor. For such an anchor driven through a plaster wall or wallboard with the flange brought flush against the inner surface thereof, the threaded bolt is unthreaded sufficiently to position the jaws as described. Operation of the tool to thrust the jaws apart causes the bolt to be drawn out axially, carrying the inner end of the anchor so as to decrease the distance between flange and inner end and deforming the anchor body for interlocking it with the wall material. Where such an anchor is initially only partly driven through the wall, due to its inner end being obstructed, the bolt is unthreaded and the jaws located between the thus spaced head and flange in the same manner.

Abstract: There is disclosed a wall anchor structure having a hollow body in which spaced ribs extend from a flanged portion at one end to a sleeve in which an axially movable nut element is captured. A bolt extends through the body from the flanged end to threadedly engage the nut. With the bolt head abutting the flange, the structure is struck or otherwise inserted through a dry wall or wallboard to bring the flange flush against the inner surface of the wall. The bolt, being slidable, is grasped at the head and pulled out to separate the head from the flange an amount permitted by the axial travel of the nut. This permits the jaws of an anchor operating tool to be inserted between the head and flange, and forced apart to forcibly separate the head and flange further, causing the ribs to deform so as to bite into and interlock with the wall material. The bolt is then threaded out of the nut and removed to permit a bracket or other support member for shelving or the like to be seated against the flange.

Abstract: There is disclosed a single hung aluminum window in which the sash is provided with plastic inserts in its stiles at their upper and lower ends, such inserts having portions which serve as guide and spacer members which bear against the jambs of the frame in which the stiles are positioned. The inserts also form housings which include respective pushbuttons and bias springs, the buttons extending through aligned openings in such housings and the inner stile faces. In the head portion of the frame are elongated stop members adapted to be swiveled between vertical and horizontal positions, and which in vertical positions prevent upward movement of the sash beyond the point wherein it is not engaged by the feet of the balance mechanisms mounted in the jambs.

Abstract: There is disclosed a metal window frame in which balance mechanisms are positioned in the upper portions of the jambs adjacent the sides of a fixed pane or panes, the front faces of the housings for such mechanisms being in a plane parallel to the outer face of a sash that is slidable from a closed position in the lower portion of the frame to a fully open position in the upper portion thereof. The mechanisms and sash are coupled via identical foot structures which are attached to the lower ends of the balances, and which have hook portions extending through the plane of the outer face portion of the sash so as to maintain engagement with the lower end of the sash throughout its normal movement. Catches in the jambs limit the upper position of the foot structures when the sash is raised to an uppermost position for removal from the frame.

Abstract: There is disclosed a pressure responsive device incorporating a snap action disc spring having arms for actuating an indicator plate with indicia thereon. In one arrangement the arms extend from the inner peripheral edge of the disc spring, and in other arrangements the arms extend from the outer peripheral edge of the spring. The indicator plate is adapted for rotational movement with lateral movements of the arms when the spring snaps, as by direct connection to the ends of the arms or by means of gearing or other provision of converting linear motion to rotary motion of a pin or shaft of the indicator plate. The plate is below a cover that has openings in which the indicia are aligned upon its rotation to the position caused by the snap action of the disc spring in response to predetermined level of pressure of fluid applied to the pressure responsive device.

Abstract: There is disclosed a bidet seat housing in which are front and rear water jet nozzles and director members through which to pass water one or the other of the nozzles via a solenoid-operated diverter valve connected to the outlet fitting on top of an elongated horizontal water tank adjacent one end thereof, such tank having its inlet fitting on top adjacent the other end connected to a water supply line via a solenoid-operated pressure regulator. An external mode selector effects operation of one of either one of the solenoids or of a warm air blower for supplying warm air blower at the rear of the seat. The water tank contains a heater and a sensor with a temperature sensitive resistor. A control module has circuitry of which the sensor resistor is a part, and effects operation of the heater as needed to maintain water flowing through the tank at the desired temperature.

Abstract: A window structure is disclosed wherein the center portion includes sliding panels which have stiles in abutment in their closed positions, such stiles having plates or ribs extending from their inner surfaces which are captured and releasably held by a latch mechanism that is pivotal on one rib and slidable along it. On the exterior of the structure, one of the stiles carries a plate that spans equal areas of both abutting stiles. The latch is symmetrically contoured, whereby observation from either side of the structure does not clarify the edge portion and direction of movement of such portion of the latch that is required in order to operate the latch and permit the sashes to be moved apart. Further, the exterior plate prevents insertion of a tool between the abutting stiles when the sashes are in closed position and latched.

Abstract: Interlocked partition strips are shown and described wherein each strip has a number of spaced parallel slots which divide the strip into segments or sections. All but one end segment have lock tab projections near one edge extending into the slots in one direction. Also, the one end segment and all other segments but the remaining end segment have lock tab projections spaced inwardly from such one edge, the latter projections extending through the slots in the same direction, but opposite to the direction in which the projections adjacent the edge extend. Thus, each slot has two spaced, oppositely directed lock tabs extending through it. At the opposite edge of each strip are spaced tab receiving openings to be interfitted with lock tab projections of a transverse strip.

Abstract: In the embodiment shown is a handle to be mounted on a door stile, wherein the handle houses a latch plate, a bowed leaf spring interlocked with the latch plate, and a cam bar for moving the latch plate from one to the other of two positions, the cam bar being of such a length that one end thereof extends beyond one end of the handle when in one position and the other end thereof extends beyond the other end of the handle when in its other position. In both positions of the latch plate, its face is in a plane parallel to and confronts the stile. The latch plate has portions at one edge engaging an inner wall of the housing formed by the handle, and an elongated portion extending from such one edge passes through an opening in the wall and has a lip for latching to a jamb. When the door is closed, the cam bar in one position overcomes the spring to force the latch plate away from the jamb, and in the other position to permit the spring to position the latch plate wherein the lip thereof latches to the jamb.

Abstract: There is shown a frame in a truck cab which has an elongated lower straight portion, an elongated shorter upper portion that is curved or bowed upwards, and side portions extending between the ends of such lower and upper portions, and sashes movable along the lower portion. Fixed panes are positioned in the end portions of the frame, and the sashes are slidable so their upper ends move apart a significant distance before engaging the upper frame portion, and such distance is sufficient that in their closed positions the sashes have greater headroom in the upper frame section than the depth to which their lower ends extend into the lower frame section. Such sashes are non-removable via U-shaped or box-like guide elements secured to their lower ends, such elements having spring-like walls with flanges which extend laterally below and in interference relation with shoulder ribs in the frame.

Abstract: There is shown a pressure responsive device for operating an electric switch plunger, the device having a port to receive fluid under pressure for application to a slidable piston that engages a pressure plate arranged to actuate a snap action disc spring, and thereby actuate the switch plunger via a combination motion doubler and pressure level setting mechanism. Such mechanism includes a yoke member extending from the snap spring to the switch plunger, and a helical spring surrounding the yoke and which at one end engages the pressure plate and at its other end is coupled to an adjustment member that is threaded on a housing that surrounds the helical spring and yoke member.

Abstract: A cylinder with cross inlet and exhaust ports contains a combination piston and rod having on its piston end a piston head or face and slidably attached sealing sleeve, and its other end is rotatable via a rod bearing attached to a crankshaft. The rotational motion of the rod with the crankshaft imparts an undulating movement to the piston head during its stroke motion and, in unison with the slidably attached sealing sleeve, effects a sequence wherein the exhaust ports open ahead of the inlet and close before the inlet closes.

Abstract: A pressure responsive device is shown for actuating an electric switch, such device having a port for connection to a source of fluid under pressure, the port being spanned by a diaphragm overlayed by a pressure plate that is adapted directly to actuate a snap action disc spring and a yoke member. An exteriorly adjustable threaded rod extends through the yoke member, and a helical spring has turns at one end threadedly engaging the yoke member, and turns at its other end engaging a shoe element that is threaded onto the rod. As the rod is turned in one direction, the shoe moves towards the inner end of the rod and thereby elongates the spring, i.e., places it in tension. Turning the rod in the opposite direction causes the shoe to move towards the external end of the rod and thereby place the coils of the spring in compression.

Abstract: A control shaft extends through and is rotatable in a housing parallel to a stub shaft therein which has one end extending through one wall thereof. Within the housing are four bevel gears, one being keyed or fixed to the control shaft, a second rotatable on and relative to the control shaft, and the remaining two meshing with the first and second ones and carried on a block that is rotatable on and relative to the control shaft. The second bevel gear is keyed to the larger of a pair of meshing spur gears, such larger gear being rotatable relative to the control shaft and the smaller spur gear being fixed to the stub shaft. Respective discs are fixed on the adjacent ends of the two shafts, and articulated holding devices are operable to alternately hold and release the discs.

Abstract: A plug with blade type contacts is shown in which such contacts enter a receptacle via self-sealing slits to matingly engage contacts in a dielectric filled chamber wherein adjacent receptacle contacts, and hence adjacent plug contacts engaging them, are separated by plates extending radially from a central flexible member to the chamber wall. The plates in the example shown are integral with a central sleeve or tube, and are prevented from movement out of contact separating position via interference relations of portions of the plates and portions of the receptacle housing or contacts. For foreign conductive matter entering the fluid and which might otherwise be able to bridge adjacent contacts, the plates constitute barriers to prevent such bridging and degradation of electrical integrity that would occur therefrom. For pressure compensation in use of plates and tube that are rigid, holes are provided in the lateral surface of the tube intermediate adjacent plates.

Abstract: A pair of horizontal rods of fiber optic bundles extend into a light box from external high intensity light sources. Light from the rods is directed upwardly via fixed mirrors, and thence horizontally and vertically to a viewing plate via pairs of mirrors supported in rotatable arms. Secured in the mirror arms are bearings that are rotatable in support plates, the axes of such bearings being coaxial with respective rhomboid arms. The mirror arms are caused to track the movements of the rhomboids, and different arrangements are disclosed for effecting such tracking, including external motors having shafts coupled via gears to the bearings and a servo control network with inputs from potentiometers representing the relative positions of the mirror arms and the rhomboids coaxial thereto, and pulleys and belt arrangement extending between coaxial arms.

Abstract: A partition is disclosed wherein one strip has a tab formed at the inner end of an elongated slot, such tab having score lines to facilitate inward collapsing thereof when engaged by the inner end of an elongated slot in the other strip. In the strip with the tab, the outline punched therein for the tab has pronounced shoulders spaced apart less than the width of the tab proper, so that the body of the tab locks against such shoulders when the tab is collapsed. Thus collapsed, the body of the tab extends along the surface of the other strip and prevents relative rotation of the strips towards collapsed condition.
