Abstract: This turn signal wiring replacement harness is adapted to be owner-installed in place of the worn-out or defective factory-installed signal circuit wiring. It consists of a main flexible conduit containing wiring to a flasher, signal light and signal switch on the dash board, for connection to the storage battery. The main conduit has a pair of flexible conduit branches through the right branch of which wires lead to the front and rear right turn signal lights; and through the left branch of which other wires lead to the front and rear left turn signal lights.

Abstract: Upper and lower combined cutting and anvil rolls are provided with axially-extending circumferentially-spaced grooves for receiving compression cutting blades clamped therein, with their cutting edges substantially engaging the anvil portions of the other roll. One roll is drivingly connected to the other roll by intermeshing helical gears whereby one roll can be shifted axially and thereby simultaneously shifted circumferentially relatively to the other roll in order to vary the circumferential spacing of the cutting blades of the upper and lower rolls so as to vary the lengths of the sheets cut from a web of paper emerging from a printing press by which the pages have been printed. An adjusting screw shaft engages the upper roll through a thrust bearing and is equipped with a hand wheel and lock nut wheel to shift the roll axially and lock it in position. Registering concentric annular dials between the upper axially-adjustable roll and its helical drive gear indicate the adjustment which may be obtained.

Abstract: A base metal, such as the aluminum or iron housing of a conventional rotary or reciprocating-piston internal combustion engine, and a sealing member applicable to the pistons or rotor thereof are coated with a layer of a wear-resistant alloy, such as molybdenum-ruthenium or tungsten-ruthenium alloy, either by evaporating the elements of the alloy by electron guns onto the surfaces to be coated or by vaporizing a wire of the same alloy in a vacuum chamber by the application of a high-tension electrical discharge through the wire from an electrical condenser bank. Depositing the alloy is done on a production basis by passing workpiece holders in a circular path through a vacuum chamber beneath the electron guns, followed by a realloying step through a laser beam, an acid dip, a rinsing dip, a drying by heat, and a final honing.

Abstract: An elongated base strip of flexible fabric is adapted to be adhesively but removably secured to the neck band of a garment, such as a man's shirt. A reversely-folded absorbent collar protector strip straddles the upper edge of both sides of the base strip and on its rearward side carries an elongated narrow central attachment strip, the exposed face of which is provided with a pressure-sensitive adhesive layer and a removable cover strip. Two collar-engaging hooks are optionally fastened to the opposite ends of the rearward side of the protector strip slightly below its upper edge. Attached to and projecting laterally from the opposite ends of the forward face of the base strip are two end attachment strips similar to the central attachment strip and with their forward and rearward faces similarly provided with pressure-sensitive adhesive layers and cover strips.

Abstract: A base plate carries a denture model surveyor table having model clamping fingers and a clamping screw; also a column to which is pivoted, by a ball joint, a universally-adjustable surveyor tool head including an inclined shaft horizontally pivoted to a horizontal shaft. Rotatably mounted on the forward end of this shaft is a stub shaft carrying a horizontal transverse bearing rotatably supporting the hub of a double-disc reel. Secured to the outer sides of the reel discs are two parallel chordal slide bars upon each of which is slidably mounted a chordal slider from which an axial slide bar projects perpendicularly outward. Slidably mounted on each axial slide bar is an axial slider. Depending from and tiltable relatively to each axial slider is an elongated telescoping tubular tool holder terminating in a tool chuck.

Abstract: An inflatable and deflatable thin-walled bag resembling a toy balloon is adapted to be suspended from an overhead support by an elongated flexible filamentary member, such as a cord, by an attachment device, such as an adhesive strip. The length of the cord is adjustable by an adjusting device to position the bag at the desired height for the particular stroke intended to be practiced. A sharp stroke from the tennis racquet causes the air-filled bag to fly at a decreasing speed rapidly away from the racquet, but to return much more slowly because of the effect of its light weight combined with the resistance of the air upon it. Due to the effect of this rapid retardation on the return flight of the bag, the user is given sufficient time, even after making a full follow through, to enable him or her to assume the proper stance for the next practice stroke according to the height of the bag above the floor or ground level.

Abstract: An above-ground insulated tank adapted to be filled with water has a hollow upper wall with air ducts from which a first set of flexible air discharge pipes extends downward a short distance. Disposed near the bottom wall of the tank is a second set of perforated air discharge pipes of cruciform shape permitting air to bubble upward therefrom. A third set of unperforated flat-spirally-coiled air pipes is disposed beneath the second set and rests on the bottom of the tank and is composed of copper for high heat conductivity. Rising from the top wall of the tank and communicating therewith is an air inlet stack and an air outlet stack disposed side-by-side above, and in communication with, an air control housing containing three air chambers and provided with multiple motor-driven air blowers.

Abstract: For drivingly connecting the external cylindrical surface of an inner machine element to the internal cylindrical surface of an outer machine element, such as a shaft to a pulley, forward and rearward clamping rings are spaced axially apart from one another and have circumferentially spaced aligned bolt holes disposed parallel to the axis of their internal and external cylindrical surfaces. One ring has smooth bolt holes and the other ring has threaded bolt holes, these holes receiving threaded clamping bolts. Mounted in the space between the two clamping rings are pairs of alternately oppositely facing resilient coupling rings of substantially Z-shaped cross-section having bolt holes aligned with the clamping ring bolt holes. Each coupling ring consists of radially-spaced inner and outer annular rims connected at acute angles to the opposite ends of an annular web inclined at an oblique angle to the axis of the cylindrical outer and inner surfaces of these coupling rings.

Abstract: A base metal, such as the aluminum or iron housing of a conventional rotary or reciprocating-piston internal combustion engine, and a sealing member applicable to the pistons or rotor thereof are coated with a layer of a wear-resistant alloy, such as molybdenum-ruthenium or tungsten-ruthenium alloy, either by evaporating the elements of the alloy by electron guns onto the surfaces to be coated or by vaporizing a wire of the same alloy in a vacuum chamber by the application of a high-tension electrical discharge through the wire from an electrical condenser bank. Depositing the alloy is done on a production basis by passing workpiece holders in a circular path through a vacuum chamber beneath the electron gun, followed by a realloying step through a laser beam, an acid dip, a rinsing dip, a drying by heat, and a final honing.

Abstract: This taping attachment or device applies a ribbon or adhesive-coated tape to an article moving relatively thereto, such as around a coil of strip material being wound upon a rotating mandrel, in order to prevent subsequent unwinding of the coil. This taping attachment or device consists of a tape roll holder mounted above the carrier for the article to be taped, such as a mandrel, adjacent a reciprocatory fluid pressure motor. The latter includes a piston rod having mounted on its lower end a pivoted tape applicator with a tape cutter thereon urged or positively driven in a downward tape-severing direction.

Abstract: A rectangular main frame has uprights resting upon and bolted to a shelf formed by a horizontal angle beam or corbel installed in the elevator shaft or hatchway below the floor level and at the intended location for the corridor entrance wall opening into the elevator shaft. Extending between the upper ends of the uprights is a top hanger header which subsequently supports the trackway for the corridor entrance door or doors. Also secured to the angle member is a corridor entrance sill support having secured thereto spaced parallel channel brackets projecting outward therefrom and containing pairs of keyhole slots in their vertical webs.

Abstract: Connected to the contestant game pieces of a J-shaped racecourse game are pull cords guided at a semi-circular turn by laterally-spaced guide members and at the finish line by laterally-spaced upper guide holes in the top wall, whence the pull cords pass through radially-spaced intermediate cord guide holes on a pivoted lane-length-compensating sector gear, and finally through lower cord guide holes in a fixed guide bar to connections on the winding hubs of multiple geared spools loosely and rotatably mounted upon a stationary cross shaft. The geared spools mesh with an elongated half gear on a drive shaft rotated by an external hand crank and carrying a sector gear drive gear meshing with the sector gear teeth. The teeth terminate in a lock notch engageable by a lock pin normally slidable along the top face of the sector gear until it reaches its foremost position, whereupon the lock pin drops into the lock nut to lock the sector gear until the end of the race.

Abstract: A device for parallelly feeding objects to be printed in a printing machine, which device feeds substantially parallelly an object to be printed to the feed rollers by providing a vacuum feeding sucker and a rotary vacuum ring which is lifted in synchronism with the sucker.

Abstract: This upstroke-cushioning expansible strut consists of a spring-pressed hollow upper inner arm having on its lower end a piston head reciprocable within a roughly cylindrical hollow lower outer arm, the former being pivoted to an automobile rear hatch while the latter is pivoted to the lower part of the automobile body. Mounted between the lower arm and the upper arm is an elongated hollow spool-shaped internal seal which also guides the upper arm as it is propelled upward by the lifting force applied by the operator, assisted by internal springs. The air is allowed to escape gradually through bleed orifices until the upper arm nears its fully extended position, whereupon the release of the air is halted by the covering up of the orifices by the internal seal when said orifices reach said seal, thereby cushioning the impact which would otherwise occur between the piston head on the lower end of the upper inner arm and the upper end of the lower outer arm. The internal seal also acts as a resilient stop.

Abstract: A pipe coupling for connecting pipe sections fitted into opposite ends of the coupling which is formed with a plastics sleeve having tongues formed integrally with the sleeve on opposite ends thereof. These tongues fit in openings in plastics clamping rings at opposite ends of the sleeve and engage with sides of the rings to prevent removal of the clamping rings. The clamping rings hold sealing rings of rubber material around the inside of the sleeve for sealing engagement with the pipe sections.

Abstract: A machine element consisting of a shaft having thereon an enlargement such as a gear or cam is made in composite form at a much lower cost in labor and materials than in one-piece form by providing a solid metal supporting shaft of the desired dimensions with a roughened zone, as by coarse-knurling it. A sintered powdered metal preform of suitable metal for the enlargement is prepared in a conventional manner of slightly smaller diameter and of slightly greater length than the finally-desired configuration, and with a central longitudinal bore of slightly larger diameter than the shaft, to allow for expansion of both preform and shaft when both are heated to a forging temperature of 1800.degree. F. to 2000.degree. F.

Abstract: A hollow horizontal support of inverted U-shaped cross-section has a base plate secured transversely thereto at its rearward end, and also has parallel side walls interconnected by a top wall, and further has a forward end wall with a downwardly-extending portion serving as a fixed article-gripping jaw. Slidably mounted in a hole in this end wall and provided with a movable article-gripping jaw projecting downward therefrom is a spring-pressed plunger, the forward end of which projects forwardly through the forward end wall in a push-button portion, the rearward end of which slidably engages the side wall of a hole in the front wall of a hollow rear spring abutment and plunger guide member of up-ended scoop-shaped form disposed in the interior of the U-shaped support and held therein by integral transverse lugs projecting laterally therefrom and fitting into notches in step portions of the opposite side walls of the support.
