The wedge also cooperates with locking means on the plate and channel to lock the channel to the plate.

Abstract: A file folder having a fastener mechanism on the inside and provided with a wide back for carrying identification markings and covers extending from the wide back. The folder is made of one piece of hard cardboard on its open side, and has an additional narrow identification back. This narrow identification back, as well as the wide identification back, is connected by folding and bending with an adjacent cover each, through a side edge strip connected in one piece and produced by folding and bending. The side edge strip reaches around the free edge of the other folder cover and is disconnectably attached to it. The side edge strip of the additional narrow identification back has, on its free edge, a projecting insertion tongue, and the facing folder cover has an associated insertion slot.

Abstract: An improved animal prod having a base shaped to engage a portion of the animal's hindquarter and a thigh engaging assembly shaped and positioned to engage a portion of at least one of the animal's hind legs generally near the animal's inside thigh and generally near the animal's hindquarter in an operating position of the animal prod with the base engaging the animal's hindquarter.

Abstract: A toy vehicle is provided for use in a toy vehicle game including an endless track defining at least two parallely extending vehicle lanes in which two or more toy vehicles are operated. The toy vehicles each include a reversible electric rotary drive motor and a transmission operatively engaged between the motor and the drive wheels for driving the vehicles in a forward direction regardless of the direction of rotation of the drive motor. The drive transmission has an idler drive member mounted on a rotatable frame in driving engagement with the output of the motor and is moved into driving engagement with one or the other of the drive wheels depending upon the direction of rotation of the drive motor.

Abstract: A dental handpiece equipped with an improved rotor cartridge and, in particular, a rotor cartridge replacement assembly for such a handpiece. The rotor cartridge takes the form of a subassembly of a rotor, bearings for the rotor, resilient rings supporting the bearings, and a plastic cup member extending about the lower bearing assembly and the resilient support ring therefor.

Abstract: An improved pet relief station for the receiving of pet excrement, the relief station comprising a screen pan having a screen portion, and a pair of receiving pans that are alternatively stackable one in the other. The screen pan is placed in one of the receiving pans, and this pan is in turn stacked in the other receiving pan. Pet litter is disposed in the screen pan to cover the screen portion thereof. Once pet solids have been deposited on the pet litter, the solids are removed by lifting the screen pan, sifting the pet litter which separates the pet solids onto the screen portion, and disposing of the solids. Immediate reassembly of the relief station is afforded by separating the receiving pans, positioning the screen pan in the empty receiving pan, and then pouring the litter over the screen portion of the screen pan. The receiving pans are then restacked.
