Filed: 1993-07-20
Abstract: A wallet style compact disc storage unit (10) includes an enclosing case (12) and an interior structure (14) adapted to releasably hold a plurality of compact discs (16). The enclosing case (12) includes a clamshell structure including a first shell member (22) and a second shell member (24), each having corresponding cushions (40,42), are connected by a living hinge (26) and releasably secured by a slide latch (28). The interior structure (14) includes an even plurality of disc receiving plates (56) formed in four plate modules (58) with each plate (56) being adapted to support one of the compact discs (16) in a releasable manner. Adjacent pairs of plates (56) are hingedly connected by alternating first hinges (104) and second hinges (106) to require accordion type folding of the respective plates (56). Pretensioning of the interior structure (14) and alternating opposingly biased hinge structures cause the plates (56) to precess with a distinctive "flipping" motion to conveniently present the discs (6) to the user for viewing and removal.

Patent CA-2147628-A1 (CA)
Title: Lamp reflector
Inventor: GRENGA JOHN J
IPC: F21V7/22
Filed: 1993-10-26
Abstract: A lamp reflector comprises a pre-formed member molded from a polymer into a smooth and continuously curved shape. The members have a rigidity characteristic sufficient for maintaining its shape. A reflecting layer is bonded directly to the molded member to provide a reflector surface without facets or sharp angles. The shape of the member is comprised of a rear portion be-ing an involute spline and side portions being defined by conic sections. The method of providing such a reflector decreases the amount of light reflected back into the lamp and trapped or absorbed within the lighting fixture. The method further eliminates the need for adhesive layers between the metal reflecting layer and the substrate which generally decreases the optical efficiency of the luminaire.

Title: Dishwasher and control therefor
Inventor: OUTCALT ALAN G
IPC: A47L15/46
Filed: 1996-11-14
Abstract: The invention is a dishwasher and a control therefore in which the control comprises multiple parallel loads, including a motor. The motor and the other loads are connected to one side of a power source by a motor relay, which is controlled by a processor. All the loads, except the motor, are connected to the other side of a power source by semiconductor switches with each load having a corresponding switch. The motor has an unswitched connection to the other side of the power source. The power to all the loads, including the motor, is controlled by the motor relay. If one of the switches fails in such a way that the circuit for one of the loads is closed, then the load will be shut off when the motor relay is opened to shut off power to the motor. Thus, it is possible to prevent the failed load circuit from operating during the entire wash cycle.
