Abstract: The milk claw has a frusto-conical cover fitting on and oriented to the bowl. The four inlets to the cover are downwardly and tangentially arranged on the cover so incoming milk hugs the inside wall of the cover as it swirls around the cover for discharge into the bowl. The bowl has a downwardly spiraled path leading to the outlet arranged on a radius of the bowl. A dam separates the start of the spiral path in the bowl from the outlet and serves to prevent the flow at the outlet from interfering with the flow entering the bowl.

Abstract: The socket wrench extension is provided with a push-on/quick release locking arrangement. The extension has a square drive end having a transverse bore in which the lock balls are mounted for movement between a lock position in which one ball projects from one end of the bore far enough to engage a cooperating cavity in the drive recess of a socket or other tool and a release position in which both balls lie within the cross section of the drive end. One end of the bore being closer to the drive end than the other end of said bore. An axially extending groove intersects the end of the bore further from the end of the extension. A sliding member moves between a lock position and a release position and has said lock tab engaging one of said balls when the member is in its lock position. The member has a limited range of movement enabling the lock tab to be raised above the groove by means of force applied to the tab by the balls.

Abstract: Movement of a wing frame to folded position moves a locking member into position to be engaged by the arm which actuates the wheels to lowered position. When engaged, the lock prevents the wheels from being raised. To disengage the lock the wing must be unfolded first to enable the locking lever to rise out of the way when the arm is actuated to disengage the lock. The entire operation is controlled hydraulically and the farmer need not get off his tractor to lock or unlock the rig.

Abstract: The dynamometer has a fixed frame in which a Hall effect generator measures the flux density at a location indicative of the flux in the gap between the rotor and the inductor rings. The gap flux density is influenced by the flux induced by the field and the opposing emf generated in the rings as the rotor rotates. The Hall voltage H.sub.V is related to and substituted for the flux density B in the formula Torque ##EQU1## where r and s are constants proportional to eddy resistance and inductance and f is the frequency in cycles per second. The Hall voltage and a speed pulse signal are fed into computer means to provide a direct readout for torque, horsepower and speed.

Abstract: The parallel rails have a double tee cross section and the leg of the rear T fits into slots in the sides of the frame. When the frame is welded, the rails are captured with the front slots ahead of the frame so menu strips and price modules can be mounted from either end and will mesh with each other or lie over the frame to prevent light leaks.

Abstract: A cover for an ostomy pouch having a drain fitting at the bottom of the pouch. The cover has an opening allowing the pouch to be mounted in the usual manner on the plate worn by the patient. The cover has an integral pocket which receives the drain fitting to prevent irritation of the sensitive portions of the anatomy.

Abstract: In both the socket linkage and the ball bearing assembly the formed metal engages the curvature of the ball more than 90.degree. which retains the parts in assembled relationship. The forming is accomplished by cupping metal into a die with clearance between the die and the punch less than the metal thickness to cold extrude the metal past the minimum clearance. In the case of the socket linkage the ball is used as the punch and the forming operation completes the assembly of the ball to the socket. Each race of the ball bearing assembly must be stripped from the curved forming part (die or punch) before final assembly with the balls. If the stripping operation deforms the metal past its elastic limit, the desired shape can be restored by use of a straight walled forming part before or after the races have been assembled with the balls between the races.

Abstract: The radial internal combustion engine has two pairs of opposed cylinders arranged on axes at 90 degrees to one another. Each pair of cylinders has opposed pistons, interconnected by a piston rod and scotch-yoke assembly. A piston rod is rigidly connected to each piston and extends inwardly to a heel having a load face transverse the axis of the crankshaft. A pair of rollers are mounted on the throw of the crankshaft with each roller being in alignment with and engaged by the load faces of a pair of the piston rods. Apertured retention plates on each side of each roller are fixed to the heels. The rollers engage the load faces. The crankshaft extends through the apertures in the retention plates and the plates are fixed to the heels by dowel pins positively locating and spacing the heels and the retention plates.

Abstract: A promotional device which preferably includes a laminated record which can be detached along a perforated line is attached to the bottle or can carrier by means of spaced arms projecting from the device and having lock tabs which engage spaced webs in the carrier. When attached to the carrier the promotional device is positioned closely adjacent the side of the carrier and resists accidental removal.

Abstract: The seaming tool has elongated upper and lower plates hinged along their long edges to open like a book. The bottom of the lower plate has stops parallel to the hinge. The stops engage the edge of already laid floor covering and the to-be-laid material is positioned between the plates. The free edge of the upper plate now serves as the cutting guide. It is slightly closer to the hinge than the stop means to ensure a slight overlap of the materials to require a tight or force fit at the joint.

Abstract: A bow string is retained between the rubber block in the notch and the retaining pin projecting laterally from the sear which is engaged by the retractable plunger. When the trigger is mounted on the plunger pull pin is either pushed or pulled, the pin is pulled back to retract the plunger and release the sear which then releases the bow string. The sleeve on the end of the pull pin can be adjusted to adjust the trigger travel necessary to release the sear. The handle is captured between the body and the head of the connector threaded into the body so the handle can be rotated relative to the body and secured in a desired position.

Abstract: Each embodiment has a linear bearing member having a ball retainer captured in the member to retain the ball bearings when the opposing bearing member is removed from the assembly. In one embodiment the opposing member has a race resting on the balls. In the other embodiment the first member has upper and lower races and the retainer holds ball bearings against each while the opposing bearing member fits between the upper and lower balls and has upper and lower races cooperating with the balls so the opposing member can be loaded upwardly or downwardly and still run on balls.

Abstract: The bow sight has three slots angled to the vertical. A sight pin is adjustably mounted in each slot by threaded means connected to a guide plate and extending through the slot to receive a lock nut. The threaded means can be a sight pin or a sleeve in which the sight pin is mounted. In the latter case a lock nut is also mounted on the sight pin to fix it against rotation. The guide plate bears on and is guided by an adjacent guide surface parallel to the slot.

Abstract: The notch in the back of the tree stand fits over a tree trunk and the flexible steel band encircles the trunk and supports the platform. Each side of the platform is provided with a pair of legs each of which is connected to the platform by pivots arranged at 90.degree. to each other to let the legs be raised or lowered and to let the legs move inwardly. Each front leg carries a guide for the flexible steel band and also carries a locking device actuated by a knob. The device has a lock pin engageable with the band in any position of the legs and also has a pin engageable with the rear leg only in the raised (operative) position of the legs. The rear leg includes a flexible steel portion which can twist to accommodate misalignment at the connection between the legs.

Abstract: The tree stand comprises a platform having a metal support strap encircling the tree with the tree received in a diverging notch in the platform. The sides of the outer portion of the notch are convex and the sides of the inner portion of the notch are concave to permit a wide range of tree diameters to be engaged by the notch. All tree sizes in the range are contacted at widely spaced points and smaller trees are gripped by the notch. The notch is lined with a ribbed rubber facing and the strap is rubber covered where it contacts the tree.

Abstract: The screw at the upper end of the bracket leg is screwed into a tree to support the bracket with the step extending horizontally. When detached the screw can be folded into the leg and moved to a position preventing pivoting the screw relative to the leg. The bracket can now be folded. The screw can also be positioned to extend axially from the leg while unable to pivot with respect to the bracket so the folded bracket serves as a handle for the screw.

Abstract: The microfiche reader has two lenses carried by a segment mounted on an eccentric pivot which can be adjusted to move the pivot and, therefore, the lenses are in an eliptical orbit which permits the lens in the operative position to be centered on the optical path. When the segment is shifted to move the other lens into position that lens will be centered. Each lens is focused by moving the associated focusing slide in and out to move the parallel cams under the bosses carried by the lens barrel flange to raise and lower the lens to focus the image. The image is centered on the screen by adjusting the first mirror which is mounted on a bracket which pivots on a housing partition and has a wedge between the bracket and the partition. The bracket has teeth which engage serrations on the wedge so when the retaining screw is tightened the wedge is locked in place.

Abstract: The cutting tool has a circular blade having a center hole and a plurality of pivot holes spaced apart on a common radius with a handle fixed to the center hole and one of said pivot holes. A pivot shaft extends between spaced side plates and the blade is mounted on said pivot shaft. Each side plate has a throat and an anvil welded to each side plate at the rear lower corner of the throat. Each anvil has a bed plate and a back plate on which and against which the material to be cut is positioned. A blade guard depends from the handle and is contoured to lie close to the adjacent circumference of the blade and extend across the throat when the handle is in its lowermost position.

Abstract: The power tool has a spindle lock member rotating with the output spindle with a blocking member normally rotating with the lock member but capable of being restrained against rotation. The blocking member extends beyond the lock member and is provided with an opening through which the lock pin can project if the blocking member is at rest or rotating slowly but the opening precludes lock pin entry at normal operation speeds. The lock member has a recess of substantial angular embrace so the ends of the recess can be impacted on the lock pin.

Abstract: The microfiche carrier slides laterally on front and rear ball bearings between the carrier and subcarrier. The front bearing permits vertical separation of the carrier from the subcarrier and the rear ball bearing then permits the race member carried by the carrier to be withdrawn from between the upper and lower sets of ball bearings. In use the carrier is latched to the subcarrier by a latch carried by the transparent index pressure plate. The subcarrier is mounted on the base by ball bearings. The base contains the electrical components and the light source and condenser lens. The base can be withdrawn from the housing as a unit with the carrier attached.
