Abstract: A drive transmission has two counter-rotating cams bearing-mounted within a housing about a rotational axis. The counter-rotating cams have asymmetrical lobe profiles which are operative to drive a corresponding pair of coaxial drive shafts in opposite directions along the rotational axis. The asymmetry of the lobe profiles prevents the cams from locking when the lobe apexes pass the top and bottom dead center positions relative to the follower or drive pins.

Abstract: A torque drive transmission, having at least two counter-rotating cams bearing-mounted within a housing about a rotational axis. The counter-rotating cams are operative to: (i) convert a linear input to a rotary output, and (ii) drive a pair of coaxial drive shafts in opposite directions along the rotational axis. Furthermore, each counter-rotating cam defines a cam profile surface having drive and follower surfaces defining angles ? and ? respectively. The angles ? and ? are unequal to drive each cam and respective output drive shaft in an opposite rotational direction. As such, the cams may be driven in opposite directions irrespective the initial rotational position of the linear input, i.e., relative to each counter-rotating cam.

Abstract: An end-loading reinforced mailing or shipping box is formed from a single blank of sheet material and includes integral extensions which are wrapped about the box to define a surrounding protective shipping wrapper. The box may be of the top-opening variety. The protective wrapper includes end flaps which provide additional reinforcement at the ends of the package. Assembly of the integral box and wrapper requires only one straight line gluing operation by the box manufacturer and only one folding and gluing operation by the packager who receives the box and wrapper in a partly folded and glued condition. The packager end loads the products or articles into the open ended package and then needs only to fold and glue the end flaps. No right angle or timed folding or gluing operations are required. The package includes tear strips which facilitate opening a wall of the wrapper and permit the inner box to be removed. Thereafter, the box-like wrapper may be used as a protective storage box for the inner box.

Abstract: A container for holding and dispensing small articles such as candies, pills and the like is formed from a single die cut blank. The container has an opening in its front wall and a slide is movable vertically behind the front wall to alternataly open or close the opening. The upper end of the slide is attached to one of the hinged top flaps of the container during assembly to enable the slide to be operated by raising or lowering the top flap. The slide portion is attached to the blank by one or more small, rupturable connections which serve to seal the box in a closed position until it is ready for use. The slide embodies an improved construction which retains the slide in place in proximity to the inner surface of the front wall of the box, during its full range of movement.

Abstract: An end-loading, top-opening box for mailing and storing checks or the like is formed from a single blank including integral extensions which are wrapped about the box to define a surrounding protective mailing sleeve. Assembly of the integral box and wrapper requires only one straight line gluing operation by the box manufacturer and only one folding and gluing operation by the packager who receives the box and wrapper in a partly folded and glued condition from the manufacturer. The packager end loads the checks into the open ended package and then needs only to fold and glue the end flaps. No right angle or times folding or gluing operations are required. The user opens the package by tearing the single glued flap of the wrapper and then unwrapping the wrapper and tearing it along a perforated weakened line at the juncture of the wrapper and the box tray. There are no required glue connections between the box lid and tray and the box can be top-opened easily and without destroying the box.
