Abstract: A tubular battery-receiving casing has a resilient member at one end urging a first conductor into electrical contact with one terminal of a battery assembly. Such first conductor includes a portion extending lengthwise along a side of the casing. At the other end of the casing, a lamp assembly has a conductor with a V-shaped annular portion forming a flared groove. Such annular portion is in electrical contact with the other battery terminal through the positive and negative terminals of a lamp. A switch member in the form of a long loop of conductive material return bent at both ends is slidable lengthwise of the casing to connect and disconnect the base and lamp conductors. The leading end of the switch loop fits in the flared groove of the conductor for a reliable electrical connection.

Abstract: An upright mechanical arm is pivoted to a freestanding base for grasping by a player to simulate an arm-wrestling contest. The arm is power-driven in a given direction by a hydraulic jack. The force applied by the jack is adjustable. Switches detect grasping of the mechanical arm by the player and positioning of the player's elbow on an elbow pad. Such switches are interconnected with control of the hydraulic jack to cut off the supply of hydraulic liquid automatically. Bells and buzzers can be provided to indicate when the game has been "won" or "lost" by the player.

Abstract: A hanging cord is threaded through the top selvage of the net or web of a fishnet assembly and is secured at regularly spaced locations to separate anchor blocks which, in turn, are secured to the fishnet corkline. The anchor blocks have rigid bodies and swingable connectors with arms projecting from the block bodies for attachment of the hanging cord to the connector arms, such as by clips clamping the hanging cord and having lines fitted through eyes in the arms. The securing of the anchor blocks to the corkline can be by straps or staples threaded through the block bodies and tightenable to clamp the blocks to the corkline. The bottom selvage of the net can be connected to the lead line in the same manner by threading a separate hanging cord through the bottom selvage and securing it at regularly spaced intervals to corresponding anchor blocks clamped to the lead line.

Abstract: A disk carrying bell cranks in circumferentially spaced relationship is located at the side of a supply conveyor opposite a discharge conveyor and the attitude of the bell cranks is controlled by cam followers carried by the bell cranks engaging a stationary cam for the purpose of moving bell crank arms to poke pieces moved in abutment by the supply conveyor onto the discharge conveyor for movement by it in uniformly spaced relationship.

Abstract: An auxiliary support for moving car trailers or truck trailers is supported by wheels on an axle and has a drawbar at its front end. To facilitate connection to a trailer and prevent the auxiliary support from tilting, the auxiliary support is provided with a detachable outrigger that can be connected to the axle at the side opposite the drawbar and has a swivelling wheel.

Abstract: A front body or plate for disposition in front of an arch wire is connected to a fork for disposition behind the arch wire by a crosstie forming a mounting that can be slid lengthwise of the arch wire to enable the fork to embrace the body of a tooth bracket behind the arch wire. A saddle projecting from the front body opposite the fork projects rearward to form a socket engageable with the arch wire by movement transversely of the arch wire. The prong of the fork nearer the rearward projection of the saddle may be shorter than the prong of the fork farther from the rearward projection to facilitate installation of the mounting.

Abstract: A valve movable elevationally in a valve casing between a lower closed position and an elevated open position is or carries a magnetizable component of magnetic means. Upward movement of the valve is limited by engagement with an annular stop flange projecting downward from the upper portion of the casing. A permanent magnet component of the magnetic means is received inwardly of the annular stop flange and is movable upward by cooperating screw threads to separate the magnet component from the armature carried by the valve after the valve has been raised from closed position into engagement with the stop flange by elevational movement of the permanent magnet component relative to the valve casing.

Abstract: Twin combined radial-and-thrust antifriction bearings in a mounting for a rotatable member, such as a tunneling cutterhead or a tunneling cutter, can be tightened or preloaded by pressing spaced bearing races against a spacer ring therebetween to contract the spacer ring. Alternatively the rotatable member may be a cutter composed of a rim mounted on a hub having an external circumferential groove extending partially under the base of such rim by a retaining ring received in such groove and having portions thereof staked beneath the rim to anchor the retaining ring in place. The cutting rim may be of generally equilateral triangle cross section having opposite base angles clipped to provide narrow parallel walls and the apex being truncated to provide a crest included angle of 80 degrees to 100 degrees. The slant slides of the cutting rim are concave to enable the apex of the rim to be sharpened more effectively.

Abstract: A shingle or shake panel is composed of shingles progressively increasing in width from one end of the panel, the narrowest shingle or shake being at least substantially three times the offset between adjacent shingle panels in adjacent courses. Apparatus for making such shingle or shake panels trims the individual shingles or shakes to width, accumulates them in a storage bin or wheel and dispenses the shingle or shakes from such storage bin or wheel to a fabricating table where the shingles or shakes are integrated by a strip secured to their outer face at a location such that the edge of the strip farther from the butts of the shingles or shakes is spaced from the butts of the shingles or shakes a distance equal to the weather exposure of the butt portions of the shingles or shakes.

Abstract: A skeg unit mounted on a raked barge stern counter is a box lattice structure including an athwartships row of upright generally parallel vanes having their upper ends connected by an athwartships upper horizontal tie plate and their lower ends connected by a horizontal lower tie plate. The box lattice structure is mounted to the barge stern counter by struts spaced athwartships of the barge of a length to locate the upper tie plate below the loaded waterline of the barge. The vanes are of airfoil cross section and the outboard vanes are toed out. The horizontal tie plates are of airfoil cross section and have negative angles of incidence, the negative angle of incidence of the upper tie plate being greater than the negative angle of incidence of the lower tie plate.

Abstract: A print pallet composed of a dental tray holding a filler pad of thermoplastic material can be warmed to plasticize such material and inserted into the mouth of a person to be identified to be stamped by the occlusal surfaces of that person's dental arch to imprint a print of such arch occlusal surfaces on the pad. Such print record can be preserved or recorded by various media for later comparison to establish the identity of the person when deceased or incapacitated.

Abstract: A head (9) projecting from the end of a rod body (1') or from the apex of a flat trifurcated quadrant body (1) has an offset fixed prong (10) projecting from its end which is crossed by a movable prong (22) carried by a rocker (20) mounted on the head and tiltable to alter the spacing between the prongs. The tip portions (13 and 25) of the prongs have notches (14 and 26) facing away from each other to hold a ligature ring (37) in stretched condition for application to the wings (44 and 45) of an orthodontic tooth bracket (39). The tip portions of the prongs are canted relative to the prong shanks to be disposed in parallel planes and a line passing through the notches is at an angle to one edge of the body. The notch (26) in the movable prong (22) is deeper than the notch (14) in the stationary prong (10) and the portion of the shallower notch (14) adjacent to the tip of the prong forms the prong tip as a probe.

Abstract: A hanging cord is threaded through the top selvage of the net or web of a fishnet assembly and is secured at regularly spaced locations to separate anchor blocks which, in turn, are secured to the fishnet corkline. The anchor blocks have rigid bodies and swingable connectors with arms projecting from the block bodies for attachment of the hanging cord to the connector arms, such as by clips clamping the hanging line and having pins fitted through eyes in the arms. The securing of the anchor blocks to the corkline can be by straps threaded through the block bodies and tightenable to clamp the blocks to the corkline. The bottom selvage of the net can be connected to the lead line in the same manner by threading a separate hanging cord through the bottom selvage and securing it at regularly spaced intervals to corresponding anchor blocks clamped to the lead line.

Abstract: A transmitter is mounted for movement with a skier or other self-propelled sportsman and transmits ultrasonic or electromagnetic waves toward the stationary medium over which the skier or sportsman is moving. An element of the same transmitter or a separate transducer detects waves reflected from the stationary medium. A computer calculates the speed of the skier or sportsman from the Doppler shift of the reflected waves and actuates a readout unit to indicate the speed to the skier or sportsman. The readout system has a head-mounted display including a character generator and a semitransparent reflector in which the character generator is viewed so that the speed indication appears superposed over the normal background in the viewing direction.

Abstract: Opposing jaws of a retractor are pivoted together and extend oppositely from handles manually swingable to move the jaws relatively toward and away from each other. Generally rectangular blades extend downward from the swinging ends of the jaws and have planar leading bottom portions continguously engageable for fitting between closely adjacent bone such as metatarsals. The trailing portions of the blades are flared outward and rearward from the planar contiguously engageable portions for wedging the adjacent bones apart and have concave depressions for receiving the bones. With the bones received in the concave depressions, the jaws are swung apart to spread the bones and maintain them in spread-apart condition for convenient access to the facing surfaces of the bones, such as to excise a neuroma.

Abstract: An arcuate fairlead for mooring lines has an arcuate row of grooved line-engaging shoes of plastic material which shoes can be removed and replacement shoes can be installed without disassembling the mooring line from the fairlead. The fairlead is of generally triangular shape supported by trunnion and bearing means at its upper tip and adjacent to its apex enabling the fairlead to swing about an upright axis for self-alignment with a stretch of mooring cable beyond the lower tip of the fairlead.

Abstract: A C-shaped bushing has a pair of spaced walls with inner and outer surfaces adapted to be inserted between the front and rear coupling members of a frame connected strut arm and a pair of opposed intermediary lugs projecting from a front axle of a four wheel drive vehicle to maintain the axle in positive caster alignment. The bushing has spaced side webs arranged to engage the exterior sides of the coupling members and prevent the bushing from sliding out of the members.
