Abstract: A composition and method whereby aluminum scrap, including consumer scrap, is recycled and fabricated into aluminum sheet and aluminum containers. Aluminum scrap is melted in a heated furnace to form a melt composition. The melt is adjusted to form the present composition, consisting essentially of silicon, 0.1-1.0%; iron 0.1-0.9%; manganese 0.4-1.0%; magnesium 1.3-2.5%; copper 0.05-0.4%; and titanium, 0-0.2%, the balance being essentially aluminum. Aluminum scrap comprising consumer scrap, plant scrap, and can making scrap is heated to form the melt composition, which requires a minimum amount of adjustment to arrive at the present alloy composition. The composition is then cast and fabricated into sheet having strength and formability properties making it suitable for container manufacture. Container manufacture according to the process and composition of the present invention comprises drawn-and-ironed can body manufacture and easy-opening end manufacture.

Abstract: A can printing machine of the type having a rotating assembly of mandrels contacting a rotating printing blanket for transferring decoration from the blanket to cans on the mandrels is provided with mandrel assemblies which are axially alignable with the printing blanket to permit axially uniform decoration of the cans. Each mandrel assembly comprises a rigid central member; a cylindrical sleeve mounted on the central member for receiving thereon a can to be printed; first mounting means pivotably mounting the sleeve to the central member at an axial midline of the can; and second mounting means accommodating pivoting and positioning the sleeve in a rest position to permit loading and unloading of the cans. Since the sleeve rotates relative to the central member to transfer circumferential decoration from the printing blanket to the can, the first and second mounting means permit rotation of the sleeve and rotatable pivoting.

Abstract: Apparatus for holding a first object or objects in a fixed position relative to a second object comprising an elongated continuous length strap for engaging and holding the first object; strap attachment apparatus connected to opposite ends of the strap for attaching the strap to the second object; winch-type strap tightening apparatus operatively associated with an intermediate loop portion of the strap for adjustably tensioning the strap; the winch-type strap tightening apparatus comprising a rotatable split shaft assembly for winding and unwinding the strap to adjustably tension the strap defining a slot for receiving an intermediate, variable length loop portion of the strap to enable adjustment of the effective length of strap; ratchet apparatus associated with the shaft assembly for releasably holding the shaft against unwinding rotation during and after tensioning of the strap; a one piece frame member for supporting the shaft assembly and the ratchet apparatus; and the split shaft assembly comprising

Abstract: A separator for material which includes components of different specific gravities and sizes, includes a series of spaced, parallel shafts disposed in essentially the same plane, which may be tilted upwardly. A series of non-circular discs, such as elliptical, three lobed, etc., are mounted on each shaft and interspaced with the discs on adjacent shafts. A pipe, on which the discs are mounted, or a spacer mounted on the shaft provides circular surfaces between the discs which clear the projections of the discs of adjacent shafts but when the disc surfaces between the projections come opposite the pipe or spacer, cause holes or spaces to be produced, through which material may fall, if sufficiently small. As the discs rotate, they not only cause the holes to open and close, but also propel the material both upwardly and forwardly. The discs may be mounted on a shaft in a spiral relation, so that not only is the material pushed upwardly and forwardly, but also laterally.

Abstract: A one at a time can crusher, specifically for recycling aluminum cans, includes an aligning and separating feed chute for cans leading to an end-to-end crusher, and a contact arrangement for detecting the type of can, actuates a solenoid crusher. The unit includes storage for a large number of crushed cans, and a magnetic metal and glass rejector, with an overweight can rejector when used for aluminum.

Abstract: An elongated strap, having metal threads to deter cutting, includes a non-removable ring at one end and a combination lock secured to the other end, for providing an over the shoulder carrier for skis and poles, and a wrap-around lock for securing skis and poles to an anchor.

Abstract: A personal alarm device which provides for both intermittent actuation of a personal alarm as well as irreversible actuation of such alarm by the provision of multiple actuation modes including a positive displacement device which is lever and spring controlled to move a pin within the device out of restraining engagement with an alarm actuator mechanism in a manner which will prevent deactivation of the alarm by return of the pin to its previous position.

Abstract: A secondary container packaging material for use in six pack can wraps, six pack bottle carriers, twelve pack carriers, etc., comprising a composite of a paper material laminated to a plastic film. The plastic film provides tear resistance to the composite, so that paper material may be used which has a tear resistance less than that of other secondary packaging paper materials. The reduced tear resistance allows the use of paper having a lower caliper, basis weight, and, therefore, cost than conventional secondary container packaging material. Natural kraft paper and recycled paper of 12-16 point caliper are preferred for use with the present composite. The plastic film may be 0.25-2 mils thick and is preferably formed of polyethylene terpthalate, polyethylene, polyvinylchloride, polypropylene, or cellophane. The preferred films are transparent and permit reverse printing on their inner surface to provide abrasion resistant decoration visible through the film.

Abstract: Thick, resilient, flexible pad with a sloped top surface and sloped sides provides for safe, non-jarring leg exercises involving running, squatting, squat-running, leg joint pivoting, balance and the like.

Abstract: A swimming pool cover consisting of a sheet of transparent, flexible, pliant plastic of a size to cover the water surface of a pool with an overhang of a several inches permitting folding back all edges, a foamed plastic cylinder in the fold around the pool periphery and a plurality of tubular clamps maintaining the folded edge around the foamed plastic cylinder.

Abstract: A face mask shaped for the lower face below eye covering goggles includes a central attachment for securing to the nose piece of the goggles, and side holders for securing to the sides of the goggles, and a verturi nose covering on the mask to draw exhaled air from behind the mask permitting a fresh air flow behind the mask while moving.

Abstract: A quick release sling for fast shouldering and firing of shoulder-held small arms, having an adjustable size loop of a strap, which loop may be passed over the shoulder and torso of a user for weapon carrying across the user's chest with the adjustable loop is attached to a D-ring on the weapon's butt. A short strap is attached to the weapon's forearm, and a short strap is rapidly releasably secured to the loop, so that upon releasing the forearm strap from the adjustable strap, the weapon's barrel is free for shouldering the weapon for use. As a safety feature, the sling, also, includes a locking device to releasably secure the short forearm strap to the adjustable size loop, thus preventing accidental release of the weapon's barrel.
