Patent EP-0246760-A2 (EP)
Inventor: CHU ALBERT E
IPC: G01N33/545
Filed: 1987-04-24
Abstract: An assay device for the detection of one or more components in a liquid sample, specifically antigens or antibodies in a biologically derived sample. The device defines a chamber (12) of variable volume which is essentially sealed except for a membrane (24) across an inlet port. The sample is placed on the exterior of the membrane (24). It is drawn to the chamber by suction created by decreasing the volume of the chamber (12). Liquid within the chamber (12) is forced out of it under internal pressure created by decreasing the chamber volume. The chamber volume can be varied by twisting of a threadedly mounted piston (16) in a body. In one embodiment, a sandwich assay for the detection of an antigen in a sample, the antigen is bound to immobilized antibody on a distinct region of the membrane and is also reacted with labeled antibody for detection. The sample is cycled through the membrane by varying the chamber volume.

Abstract: A pair of locating washers (34, 36) are applied over the holes (84, 86) in the bottom mounting lugs (24, 26) of the kinescope (20). The washers (34,36) have apertures (44,46) which are precisely referenced with respect to the position of the kinescope screen (38) such as by using oppositely-disposed locating marks (104,106) on the screen (38). The TV cabinet (22), on the other hand, is equipped with a pair of tapered guiding posts (74, 76) on the inside front surfaces (70, 72) thereof, which are similarly referenced relative to the rectangular opening (78) of the cabinet (22). When the kinescope (20) is mounted in the cabinet (22), the cabinet guiding posts (76, 78) are received into the kinescope-mounted locating washers (34, 36) to assure registration between the kinescope screen (38) and the cabinet opening (78). The kinescope (20) is fixedly secured to the cabinet (22) by a plurality of screws (64).

Abstract: Method and apparatus for performing eddy current flaw inspection on workpiece material such as steel bar stock. A drive mechanism propels a workpiece (12) longitu­dinally along a workpiece path. An array of electro­magnetic transmitter coils is disposed about the workpiece path. An electromagnetic source energizes the transmitter coils under control of multiplexing circuitry. The multiplexing circuitry and source actuate respective transmitter coils in a predetermined iterative sequence. This sequential actuation induces eddy currents in the workpiece at a succession of locations extending iteratively about the workpiece circumference. Circuitry coupled to multiple, differentially wound sensing coils detects variations in eddy currents produced in the workpiece and utilizes these detected variations to produce flaw indicating signals.

A cutter (21) is provided in an end of the front flange (15) and an intermediate portion (C) of the cutter is protruded toward a base (11a) of the box (11). When the film (30) pulled out from the box (11) is led between the front flange (15) and the front panel (18) and is further pulled in the horizontal direction with the lid member (14) being closed, the middle portion of the film is cut by the protruded portion (C) of the cutter (21) and the cutting operation of the film is advanced along the cutter (21) so that the film (30) is smoothly and completely cut into a slightly V-letter shape when the film (30) is further pulled in the horizontal direction as it is. Thus, the cut film is fully spread horizontally without wrinkle and intertwinement and the spread film can be used to cover a tray or the like.

Abstract: 2.1 In band-limited frequency-modulated transmission systems such as the transmission of television signals via satellites, a dispersal signal is superimposed onto the television signal to be transmitted before it is frequency-modulated. This leads to disturbances in satellite television receivers. In a known circuit, a correction signal characterising the amplitude of the dispersal signal is generated by evaluating the synchronisation signals and this correction signal is additively superimposed on the input signal. The novel circuit should also provide for compensation of the disturbances caused by the dispersal signal if no standard-oriented synchronisation signals are available. 2.2 This is achieved by means of a circuit which generates overshoots on a reference level of the signal. These overshoots, which differ from the useful signals with respect to their level are evaluated with respect to amplitude and used for generating the correction signal. 2.3 Satellite television receiver. <IMAGE>

Abstract: A satellite communication system includes a plurality of mobile stations which are situated on the earth and a communication satellite which is communicable with the mobile stations by radio signals over a plurality of spot beams. The satellite applies single sideband amplitude modulation (SSB-AM) to analog signals which are sent from the mobile stations, applies digital modulation to coded voice and data, and separates signals in the form of frequency-division-multiplexed (FDM) signals on a channel basis by a transmultiplexer method which is implemented by demultiplexers (32(1),32(2)) of a transponder. Baseband matrix means (34) is provided for connecting an output of any of the demultiplexers to one of the spot beams to be transmitted. Further, transmitting means (38(1),38(2)) is provided for time-division-multiplexing outputs of the baseband matrix means to form a transmit frame and transmitting it in the form of a TDM signal. On the other hand, each mobile station includes a receiver (30(1),30(2) for selecting a channel signal to be received out of the TDM signal which is sent from the transmitting means of the onboard transponder, and demodulates it to regenerate a signal.

Abstract: A television receiver includes a phase-locked loop (PLL) (226-232) which generates a clock signal (CLK) having a frequency of N times the line frequency and being phase-locked to the horizontal line synchronizing signal (HSYNC). The clock signal produced by this PLL has a frequency which tends to jitter between N+1 and N-1 times the line frequency. To compensate for this jittering in the frequency of the clock signal, phase alignment circuitry (236) is coupled to the PLL to align the phase of the clock signal to the horizontal drive signal (HD) produced by the PLL on the occurrence of each horizontal drive pulse. The PLL may also include a delay element (234) which delays the horizontal drive signal applied to the phase comparator of the PLL. This delay element effectively advances the phase of the horizontal drive signal and the line-locked clock signal with respect to the horizontal sync signal to compensate for signal processing delays imparted in the generation of the horizontal drive signal and the clock signal.

The web is advanced through an entangling station on a conveying means which supports an entangling member having a symmetrical pattern of fluid pervious void areas. The divergent jet sprays which are disposed above the entangling member direct a continuous curtain of fluid onto the web, coacting with the entangling member to entangle web fibers into a coherent lattice structure. The divergent jet sprays are provided by nozzles having wide orifice diameters which accommodate less complex fluid recirculation and filtration systems than employed in the prior art columnar jet processes.
