Inventor: STETTLER RICHARD JAMES
IPC: F23R3/30
Filed: 1980-09-10
Abstract: A combustor assembly in an automotive gas turbine engine includes a continuously ignited, pilot flame tube assembly (65) supported on a combustor dome (44) immediately downstream of a prevaporization prechamber (32) with a fuel and air swirler (30). The pilot flame tube assembly (65) has an air swirler and fuel nozzle supported on an interior bulkhead and is associated with a fuel system (100) that maintains a shielded pilot flame (95) to prevent flameout of flammable air fuel mixtures in a main reaction chamber (46) of the combustor (10); the fuel system supplies greater fuel to the pilot flame tube assembly (65) at engine fuel start and stop to produce an extended flame plume (106) that extends into the reaction chamber (46) to burn residuum of fuel when the air fuel ratio in the main reaction chamber mixture is below the flammability limit of the fuel.

Title: Flat panel display device and flexible circuit intended to receive and establish contact with a multiplicity of solid state devices such as light emitting diodes.
Inventor: HINTZE WILLIAM
IPC: H01L23/28
Filed: 1980-09-10
Abstract: Flat panel display device comprises a multiplicity of LED's arranged in parallel rows and parallel columns in accordance with a grid pattern. First bus conductors extend parallel to the rows and each of the LED's is electrically connected to one of the first bus conductors. Second bus conductors extend parallel to the columns and each LED is connected to one of the second bus conductors. The first and second bus conductors are on the oppositely facing surfaces of an insulating film and the LED's extend through openings in the film located on the grid pattern. Contact with the LED's is achieved by tap conductors which extend from the bus conductors to the LED's. A rigid grating is mounted against the film and has open cells which are located in accordance with the grid pattern. Each LED extends into one of the cells and the internal surfaces of the cells serve to reflect the light of the LED's towards the viewer. The grating also serves to support the film during assembly of the LED's to the film and to support the film after the LED's are assembled.

Abstract: A three-dimensional television system comprising an adapted transmitter (1'), which in further respects does not differ from a colour television system in accordance with the PAL, NTSC or SECAM-standard. The three-dimensional display in the standard receiver (2) is based on the use of two colours, an observer observing a colour picture display screen (10) through differently coloured glasses (19, 20). In the transmitter (1'), a first picture pick-up device (12) is coupled to an input of a matrix-coding circuit (4, 5) via a low-pass filter (14). The filter (14) has a bandwidth which is not more than the bandwidth of the colour difference signal channels in the decoding-matrix circuit (7, 8) of the receiver (2). In order to improve the picture quality a second picture pick-up device (13) may instead of directly be coupled to the matrix (4) via a low-pass filter (17) having a wider bandwidth to a different input of the matrix-coding circuit (4, 5).

Abstract: Disclosed is a digital station apparatus, such as a digital telephone set, capable of being operated in parallel on a subscriber's digital loop (e.g. in an extension mode) without the need to route all the PCM signals to commom equipment. Only one of the parallel sets is active at a time; all the others are passive. In the passive state the telephone set receives only, and does not transmit. It monitors its own signal magnitude relative to the signal magnitude produced by the active "extension" on the same digital loop. When its own signal magnitude has satisfied a comparison criterion, then that passive set becomes active and both transmits and receives, while all other sets on the loop are passive.
