Title: Electronic apparatus and methods for gain control
IPC: H03G7/00
Filed: 1982-04-16
Abstract: Apparatus for providing a gain control voltage at 22 in response to an RF input signal comprises a constant current sink device 21 which drains from an input 1 of a gain control voltage generator 20 a current varying in relation to the amplitude of the RF input signal, so that the gain control voltage 22 is a function of the amplitude of the RF input signal. The sink device 21 may receive an input control signal from an AM detector (29, Figure 2) comprising a limiting amplifier and a double- balanced modulator disclosed in detail (Figures 5, 6, 8, 9, and 10). The gain control generator 20 may be a transistor circuit (Figure 3) having AF amplifier, (41-44) coupled to a DC output amplifier (45) by a voltage back-off circuit (46) and two detectors (47, 48) having short and long rise and fall turns. Input signal threshold detector (49) including trigger circuits (50) controls the discharge or otherwise of a capacitor (51) of the detector (47) so as to allow or disallow the rapid rate of the input audio signal. The constant current sink device 21 may include differential amplifiers (82, 84 Figure 7). <IMAGE>

Title: Detecting defects in a pattern
Inventor: WEST GEOFFREY ALEC WILLIAM
IPC: G06V10/40
Filed: 1982-07-08
Abstract: Printed circuits can be inspected by eye, which is fatiguing, or automatically by comparison with a master pattern by optical super- imposition, which requires great precision in handling. In the present invention analysis of optical scanning of a pattern determines the directions of boundaries of features of the pattern and employs this analysis to identify any local divergence from the prevailing direction of the boundary. The divergence BCDEFGHJ in a boundary 52 is seen on analysis of boundary directions as AB'CDEFGHH'JK and the sequence of direction changes between A and K is used to indicate a possible divergence, as is the distance along the indicated boundary compared with the direct distance between the points A and K. <IMAGE>

Title: Electric heating means in a cooking plate
Inventor: KOTSCH HEINZ
IPC: H05B3/74
Filed: 1982-12-16
Abstract: An electric cooking plate, for example a glass-ceramic hob, comprises a heater winding (1) which largely overlies a cooking zone. A temperature monitor (3) is disposed in this zone. In order to intensify the parboiling process, it is usual to operate with higher heating power, but this increased power is transferred to the cooking vessel only in the case of flat-bottomed vessels. In the case of a non-planar vessel bottom, the temperature monitor (3) may switch off the heating element before full transfer of its heat to the vessel and thereby interrupt the parboiling process. To avoid this, an additional heater winding (2), which provides a good heat transfer even in the case of a non-planar vessel bottom, is provided at the periphery of the cooking zone. <IMAGE>

Title: Dashpot fo use in a pressure gas line
Inventor: PASTERNACK ADALBERT
IPC: F16K17/04
Filed: 1985-07-02
Abstract: A sealing valve either blocks or releases the gas held under pressure in a gas cylinder, for example. When the sealing valve is opened, the flow path is opened and a pressure impact travels to the equipment connected downstream of the valve and can cause damage thereto. The attenuator valve of the invention is disposed in the pressure-gas conduit between the pressure-gas source and the sealing valve and prevents this kind of an impact from occurring. Since the attenuator valve of the invention is controlled exclusively by pressure, it can be mounted at any location in the pressure-gas conduit. The attenuator valve of the invention includes a housing and a valve body mounted in the housing which shuts off the pressure-gas conduit with the aid of a closure cone which is held in sealing contact to a conical valve recess by means of a spring. The pressurized gas in the cylinder is present above the valve body via an alternate path. When the pressure of the gas beneath the valve body drops, this pressurized gas above the valve body causes the same to be lifted from its conical valve recess against the force of the spring thereby causing a slowed flow of gas which is free of impact to pass through the sealing valve to the equipment.
