Abstract: In a hammermill or the like and employing hammerheads with sockets which receive the rotor hammer arms, slots are provided in the hammer arms to receive cross pins which extend through apertures in the hammerheads and the slots to hold the hammerheads to the arms. Spacers having a convex outer surface which is complementary to the curved slot ends and a concave inner surface complementary to the curvature of the pins are employed to positively position the pins in the desired position in the slots and thus, by use of different size spacers, enable adjustment of the radial extension of the hammerheads with respect to the arms to compensate for wear and maintain a desired clearance with the working chamber wall and thus maintain a desired particle size.

Abstract: Apparatus for use with a pad stacking and packing machine for diapers or the like includes means for tipping vertical pad stacks on end and grouping two stacks together in a horizontal row or group of pads, with the group discharged as a unit into a shipping container. In one embodiment a conveyor with a vertical run and curved run picks up the pad stacks and turns them on edge and carries them to a grouping station where the stacks are accumulated into a group and the group is laterally discharged into a shipping container. In another embodiment, a turret which rotates about a horizontal axis receives the diapers in magazines arranged around the turret. The vertical and compressed stacks of diapers coming off the stack forming machine are loaded into the magazines at one position of the turret and the turret is rotated 90.degree. to position the pads on edge at the container loading station.

Abstract: A central band of cold glue is applied over most of the length of a label. Each label is then engaged by one of several circumferentially spaced gripper fingers on a rotating head which causes the labels to pass a hot glue applicator which applies bands lengthwise of the label on each side of the central cold glue band. Each label is finally rotated to a properly positioned container where a reciprocable squeezer presses the label onto the container.

Abstract: A coil is wound on a hollow plastic bobbin and mounted in a U-shaped ferromagnetic frame, there being a pair of aligned bosses on opposite sides of the bobbin bore at one end thereof fitting into cooperating slots in the frame. A ferromagnetic core is axially movable within the hollow bobbin and is urged away from the bottom of the frame by a leaf spring. A compact plastic housing covers the bobbin, coil, and the upper portion of the frame, and electric terminals, mounted in pockets at the top of the bobbin, project through slots in the housing to the exterior. Portions of the bobbin are extruded into openings in the base of the terminals to hold them in place, and a pair of tabs on the bobbin interact with slots in the housing, and posts on the inside corners of the housing form abutments to prevent over-insertion of the tabs in the slots. A hook on the bottom of the frame is shaped to be engageable with an opening in external support elements of differing thickness to facilitate installation.

Abstract: A knob for a cooking vessel is a whistle which gives an audible signal that cooking temperature has been reached, and has a valve slide for shutting off the whistle. Supporting inside and outside knob parts incorporate halves of a resonance chamber, which makes the knob extremely simple to mold, assemble, clean, and disassemble. The valve slide rests in guides which make it impossible to assemble incorrectly, and overlaid by a knob cover.

Abstract: For resizing an ammunition cartridge casing, an expandable and contractible collet is surrounded by an axially movable internally tapered sleeve. An axially movable headed shaft for supporting a cartridge casing from its flanged end is in the collet. Shifting the sleeve in one direction opens the collet and simultaneous retraction of the shaft lets the cartridge casing drop into the collet. Shifting the sleeve in the opposite direction causes the collet to contract and resize the cylindrical casing and its flange. Returning the sleeve to its initial position allows the collet to expand and simultaneous elevation of the shaft lifts the resized casing up to the top of a work table in position to be removed by hand or to be moved to a new work station for performance of other steps connected with cartridge reloading if the resizer is built into a reloading device.

Abstract: A manually controlled set-speed-selector on the speedometer of a vehicle causes a pair of normally open electrical contacts to close when the speedometer indicator needle reaches the set point. This actuates a solenoid valve which applies intake manifold vacuum to an accelerator actuator to pull on a chain connected to the accelerator, thereby decelerating the vehicle. A vacuum relief valve enables the driver to over-ride the decelerating action for passing or emergency purposes. The flexibility of the chain enables the driver to slow down at any time by simply releasing foot pressure on the accelerator. One electrical contact is connected to the speedometer indicator needle by a torsion spring, which allows the contacts to chatter as they close due to vehicle vibration. The on time of the chattering contacts increases as the set speed is exceeded and reaches 100% at a predetermined overspeed value.

Abstract: An existing worn out floor mat electric switch is reconditioned by cutting it on three sides, severing the electric cord in two places, removing the inner parts of the mat switch, drilling out the metallic portions of the line cord, cleaning the contactor plates, inserting and reconnecting a new line cord, supplying new contractor buttons and separator strips, and reassembling and resealing the mat.

Abstract: A molten metal sampler includes a three-part refractory sample cartridge carried in a paperboard sleeve. The cartridge includes an open ended refractory mixing chamber which in one embodiment has a side entry port which receives molten metal from a side port in the paperboard sleeve. The cartridge also includes two refractory mold halves having opposed recesses which define a fill passage and a sample forming cavity. The fill passage is positioned to receive molten metal from the open end of the entry chamber. In another embodiment, the mixing chamber has an inlet in the end of the chamber and an outlet to adapt the cartridge for use in an end filling sampler.

Abstract: A mixture of liquids and solids flowing at high velocity is discharged into a well which reduces its velocity. The mixture flows from the well over a dam and is deposited uniformly onto a moving porous woven filter belt which drains the liquid and transports the solids to a place where the solids fall from the belt or are scraped from it.

Abstract: A lift with a work platform supported by a scissors linkage on a base includes a single hydraulic cylinder for elevating the linkage. The cylinder is connected between a lower link and a swing arm which is pivotally connected to the linkage. During a first lifting stage the swing arm bears against a cam surface on the uppermost link to cause an initial unfolding action of the upper links. Prior to the arm leaving the cam surface, the arm bears against an abutment on one of the lower links for a second lifting stage to cause unfolding of the linkage from the bottom. This arrangement provides a strong, smooth unfolding of the linkage. The base is provided with outriggers which can be folded against the sides of the base when not in use and which are pivoted to a transverse position for use. Links connecting the outriggers to a guide track enable positive locking of the outriggers in the operative position.

Abstract: A molten metal dip sampler or ladle comprises a cylindrical refractory sample cup which is manipulated by a handle which is held in embracing relationship with the sample cup by a paperboard sleeve. A bent portion on the handle extends beneath the bottom of the sample cup to support the mold on the handle.

Abstract: An adapter manifold to supply untempered outside air to a kitchen or other ventilating hood is in the form of an elongated box structure which has a plurality of serially arranged outlets communicating with the interior of the manifold and extending outwardly therefrom. The adapter manifold is connected to the existing hood by cutting holes in the front wall of the hood so that the manifold tubes can project into the hood and direct streams of outside air against the grease filter. The adapter manifold enables use of outside air to facilitate exhausting of fumes and odors without causing loss of substantial amounts of tempered or conditioned inside air.

Abstract: A boat hoist has longitudinally spaced lifting beams together with winch and cable means for raising and lowering the beams simultaneously by manipulation of a single hand wheel to move a boat straight up and down, there being a scissors support for each beam to insure smooth action and uniform movement throughout the length of each beam. The arrangement is such that the hoist may be employed to free the feet of the main frame from the lake bottom at the end of a season preparatory to removing the hoist from the water.

Abstract: A hollow pin set in the downstream end of the auger of a conventional food grinder has a downstream end which protrudes to an accessible outside area of the grinder and a downstream - facing shoulder which bears against the upstream side of the knife assembly of said grinder, biasing said knife against a perforated plate. An inside pin or bolt passes through the hollow pin, threadably connected therewith, and has a downstream end which protrudes from the hollow pin and which is adapted to receive a wrench. The upstream end of said inside pin or bolt presses against a compression spring. Applying a wrench to rotate the downstream end of said inside pin or bolt changes the compression of the spring and thereby increases or decreases the bias between said knife assembly and the perforated plate which the knife is biased against.

Abstract: A mixing bowl having an outwardly flared inner surface is rotated around its axis at a speed which is great enough to cause a film of liquid within the bowl to be moved upwardly by centrifugal force to the rim of the bowl. A liquid is introduced into the bottom of the bowl at a rate that permits an unbroken film of liquid to form within the bowl and move from the bottom to the rim. Particulate material is uniformly distributed in a radial direction within the bowl to contact the liquid film and mix therewith. The rim of the bowl is shaped to interact with an adjacent stationary surface to shear the liquid and particulate material mixture to increase the uniformity of the mixture. A basin is positioned around and under the rim of the mixing bowl to collect the mixture as it is thrown off the outer edge of the rim.

Abstract: Nonrotating vibrator motors are mounted on a rigid member in furniture. Electric power at different frequencies or energy levels is supplied to the respective vibrator motors. Frequency differences in the vibrations result in moving interference waves being produced in the rigid member which waves are imparted to the user of the furniture who experiences a massaging effect. Means are provided for enabling the user to control the frequency differential and amplitudes of the driving currents.
