Abstract: A decontamination device (10) including a chamber (14) for receiving articles (28 and 30) to be decontaminated by at least one of washing, disinfecting and sterilizing. The decontamination device also includes a shelving assembly (22) for suspending the articles (28 and 30) in the chamber. The shelving assembly (22) is constructed of a first body (26) suspended above the floor of the chamber (14) having a major surface (56) facing the top of the chamber (14). At least two side walls (58 and 60) extend generally upward from the major surface (56). A second body (24) having a major surface (46) facing the floor of the chamber (14) and at least two side walls (48 and 50) is stacked on the first body (26), wherein the two side walls (48 and 50) of the second body (24) mate with the two side walls (58 and 60) of the first body (26), supporting the second body (24).

Abstract: As an electronic pen (16) moves across a display screen (12), a position resolver (14) generates a series of x,y-coordinate positions which are sent to a remote computer system (20) having a relatively high latency or time delay before the positions are processed and intended display information is returned to the memory cells of a memory array (24) which controls the display on the display screen (12). During the time delay, a temporary display of the trajectory is created, preferably in light gray or another distinguishable color. Each x,y-coordinate position is compared (32) with an immediately preceding coordinate position to determine whether the pen has moved. If so, the new coordinate is stored in a memory (36) which stores a preselected number of the most recent coordinate positions and to a toggle circuit (38) which toggles a preselected bit of the display information stored in the corresponding memory cell of the memory array.

Abstract: A flap-type pressure relief valve particularly intended for relieving overpressure conditions in a vehicle passenger compartment includes a frame having an integral peripheral sealing gasket that is formed on the frame by being injection molded directly thereto. The frame is molded from a relatively rigid plastic and the gasket is molded from a plastic that is significantly more resilient and flexible but selected to permanently bond to the plastic of the frame when brought into contact therewith under injection molding conditions.

Abstract: A ball can vending machine comprises a cylindrical storage drum including a housing section sized to hold a plurality of ball cans with the longitudinal axes of the cans disposed parallel to the cylindrical axis of the housing section. The housing section includes a forward-facing discharge opening and a rear can-guiding surface, and the storage drum is supported with its disposed horizontally. A retaining plate mounted within the housing section and disposed above the discharge opening slopes downwardly toward the rear can-guiding surface. The vending machine also includes a currency validator that produces an output signal upon receiving a preselected amount of currency. A can dispenser is disposed adjacent the discharge opening such that cans within the housing section are urged by gravity toward the can dispenser along the rear-can-guiding surface.

Abstract: A bichromal ball includes a first hemisphere. The first hemisphere includes a first pigment having a first color and a first polarity. The first pigment is added to a carrier fluid and polymer mixture during formation of the bichromal ball. A second hemisphere includes a second pigment having a second color and a second polarity. The second pigment is added to the carrier fluid and polymer mixture during formation of the bichromal ball. The carrier fluid and polymer mixture have a lower viscosity than the polymer alone. The carrier fluid is substantially removed after the first and second hemispheres are formed. The polymer is left along with the first and second pigments which form the bichromal ball. A diameter of the bichromal ball is reduced after the carrier fluid is substantially removed.

Abstract: A closure cover for panel openings is formed of plastic material and comprises a cover cap carrying several resilient elastic fingers that extend from a lower side of the cover cap. Each finger carries a stop element for penetrating into the panel opening and retaining the cover in place. The resilient fingers (3) are each comprised of two small resilient bars (6, 7) between which is arranged the stop element (8) likewise designed in the form of a small elastic cross piece. The stop element (8) forms a hook with a connection area (9) located at a predetermined angle relative to the bars (6, 7) and a stop area (5) connected to the connection area (9).

Abstract: A steam sterilization device (10) including a chamber (12) having a slidable sealable door (30). A flexible insulating plastic member (74) covers the sealable door (30). The sterilization device (10) includes a frame (20, 22, 24, 28, 50) supporting the chamber (12). A front wall (60) of molded plastic covers the frame. A stop bracket (46) is secured to a door track (36) at the appropriate location below the door to limit travel. At least one counter weight (42) is secured to the door (30) by a cable (38) and a guide member (44) surrounds the counter weight.
