Inventor: AGAHI-KESHEH DARIOUSH
IPC: H01P11/00
Filed: 1992-03-18
Granted: 1995-04-25
Abstract: A dielectric filter assembly (276) comprised of a dielectric filter construction (80; 180) and a mounting bracket (182) therefor. The mounting bracket (182) forms a support surface (238, 240, 242) and includes integrally formed strip members (202) for interconnecting electrodes (130, 136)) formed upon a face surface (88) of the dielectric filter (80; 180) and a circuit disposed upon an electrical circuit board (282). Once interconnected, reflow solder connections are formed between the strip members (202) and the electrodes (130, 136) and the strip members (202) and the circuit disposed upon the circuit board (282). The strip member (202) is then severed from the mounting bracket (182) to electrically isolate the electrode (130; 136) disposed upon the face surface (88) of the dielectric filter (80; 180), while maintaining the electrical connection between the electrodes (130, 136) formed upon the dielectric filter (80; 180) and the circuit disposed upon the circuit board (282).

Granted: 1998-09-01
Abstract: A  projector  that  has  a  shortened   optical  path from a light valve to a screen and a reduction in the depth size of its system and which requires less space to mount. Rays of light emitted from a light valve  are refracted by  a  converging  lens   and  reflected by a plane mirror  to converge at the primary focal point of an elliptical  mirror  and then  travel toward the secondary  focal point   whereat the focal point of a parabolic mirror  also exists and a projection lens  is disposed.  The  light rays pass through the projection lens, are reflected by the parabolic mirror  and then brought to a parallel beam of  light that  is further collected by a Fresnel lens  to finally form an image on a lenticular lens-screen.

Granted: 1999-09-28
Abstract: A   transfer    switch   assembly    to alternatively connect an electrical load to a primary or to a secondary power source.  The transfer switch uses two conventional switches, or circuit breakers, having pivot type or linear type actuating members. A conventional linear motor is used.  The actuating members of the switches, or circuit breakers, are in contact with the movable portion of the linear motor through a coupling mecanism.   The coupling mecanism ensures that the switches, or circuit breakers, are not in a closed position simultaneously.

Title: Fluid diverter
Inventor: GONZALEZ TEODORO J
IPC: F16K11/02
Filed: 1994-08-05
Granted: 2004-04-06
Abstract: A miniature diverter valve cartridge adapted to be received in a well in the side of a solid casing incorporated into a faucet assembly which includes a handspray unit. The diverter valve cartridge is positioned adjacent to the outlet port of the faucet assembly. The cartridge includes a housing and a piston shaft mounted in the housing for reciprocal movement, with a piston and a cup valve mounted on opposite ends of the shaft. The cup valve controls water flow to the spout of the faucet assembly. When the handspray is turned off, water pressure builds up within the interior of the cartridge in a manner such that the cup valve is moved off its seat to establish water flow to the spout. However, when the handspray unit is operated, water from the interior of the diverter valve flows into a passage leading to the handspray unit, and also into a further compartment on the opposite side of the piston. A differential pressure is created, so that the pressure in the inner compartment of the cartridge forces the piston to a position which causes the cup valve to seat securely against the housing and block the flow of water to the spout, with water flow passing through an output passage through the casing to the handspray unit. The pressure differential is achieved by providing a notch in an annular rim portion of the housing separating the inner compartment from the further compartment, the notch having a selected size to create sufficient pressure differential across the piston when the handspray unit is operated to farce the valve in a direction firmly to close the cup valve on its seat. The size of the notch is made sufficiently large so that particle contaminants may flow easily through the cartridge and into the handspray passage so as to avoid clogging of the cartridge valve.

Abstract: A series of N data items are sequentially received and stored in respective N storage locations of a first memory according to the order of arrival. The ranks of the N data items are determined according to their relative values to each other. Corresponding to the stored data items, the address number of the first memory storage locations of the corresponding data items are stored in respective storage locations of a second memory according to their ranks. The storage locations of the second memory are arranged in sequential order of ranks so that the first memory address numbers are sequentially arranged in the second memory in the order of the ranks of the corresponding data items. A sequence of additional data items is received and their ranks are determined relative to the values of data items stored in the first memory. If the rank of each additional data item is determined to be higher than the lowest rank of the stored data items, the additional data item is used to overwrite the lowest rank data item. The first memory address number of the additional data item is stored in the second memory according to the rank of the additional item by moving existing address numbers and discarding the address number of the overwritten data item. The address numbers stored in the second memory are sequentially read and the contents of the first memory are read.
