摘要:
An apparatus including a base substrate and a plurality of spaced apart end brackets attached to the base substrate. A plurality of spaced apart side panel assemblies are removably mounted between a mounting portion of each end bracket. A first edge of each side panel assembly positioned adjacent to the base substrate. A shroud is pivotally attached to each one of the side panel assemblies adjacent to a second edge of the respective side panel assembly. Each shroud is movable about a pivot axis between an open position and a closed position with respect to the respective side panel assembly. A shroud engaging portion is attached to each end bracket adjacent to each shroud. A engagement member of each shroud engages a corresponding shroud engaging portion when the respective shroud is moved from the open position to the closed position for moving the respective printed circuit substrate from an inserted position to a seated position with respect to the base substrate. Fewer components are required to construct the apparatus relative to previous apparatuses, reducing the cost and assembly. Furthermore, the shrouds function as a cam device for seating the system component assembly in the chassis.
摘要:
A storage container comprising an outer shell and an insertable drawer member configured and dimensioned for receiving and storing information-bearing discs and accompanying printed matter. The insertable drawer member includes features to store the discs by contacting non-information bearing surfaces thereof as well as means for selectively retrieving the printed matter together with the disc from the outer shell. The drawer includes a top segment and a bottom segment that are hinged together. The bottom segment has outwardly extending flexible side walls with respect to the bottom segment.

A cooking device including a upper unit having an upper grilling plate hingeably attached to a lower unit having a lower grill plate. The upper unit movable relative to the lower unit from an open position to a closed position to form an enclosed cooking chamber to cook foodstuffs. The lower grill plate includes a well to contain liquid and a heating unit for heating the well to vaporize the liquid during cooking and supply vapor to the cooking chamber.

An UPS apparatus with a back-up battery and successively coupled rectifier, inverter and output filter circuits, having an improved battery charging circuit. The charging circuit has a transformer with its primary winding being part of the output filter, and its secondary winding driving a second rectifier circuit which produces the charging current. The charging circuit contains an impedance preferably connected between the transformer secondary winding and the second rectifier circuit, for capturing only a high frequency portion of the signal from the inverter stage, thereby enabling the utilization of smaller charger circuit elements.

The catalytic combination of a phosphite ester and a phenol sulfide is disclosed. The catalyst combination accelerates and mediates the esterification reaction of rosin with a polyhydric alcohol, resulting in esterified rosins having numerous advantageous characteristics and particular utility as tackifiers in hot melt adhesives.

A switched cavity laser system which includes a resonant cavity, a gain medium within the resonant cavity, a cavity switch and an output coupler. A controllable pump energy source delivers pump energy to the gain medium in response to an energy control signal. A detector is coupled with the gain medium and generates a detector signal in response to the amount of population inversion exhibited by the gain medium. A control circuit is coupled to the detector and controllable pump energy source for generating the energy control signal in response to the detector signal. As the switching rate of the Q-switch is varied, the energy control signal varies to ensure a constant level of population inversion between each pulse. In this matter, a prespecified pulse energy is achieved for each pulse independent of the switching rate of the Q-switch.

There is provided a marker buoy useful to indicate the location of an underwater structure. The buoy is made from a material having a density less than water, including first and second elongated side members and a central portion therebetween. The central portion receives an elongated twine having a weight attached to its far end. Each side member has a stud extending away therefrom at opposing ends of the buoy. The buoy automatically rotates to dispense the twine when the buoy is placed on the surface of water, and is adapted to be manually rotated by manipulation of the studs to retract the twine.
