Patent GB-2118396-A (GB)
Title: Video signal peaking system
Inventor: HARWOOD LEOPOLD ALBERT
IPC: H04N5/21
Filed: 1983-03-28
Abstract: In the luminance channel of a color TV receiver, a horizontal peaking signal (18) representative of the difference between delayed and undelayed luminance signals is subject to coring (25), with the level of coring subject to variation. The residual peaking signal remaining after core cancellation, is subject to gain controlled signal translation (19), and then combined with the luminance signal to form a peaked luminance signal (21). A frequency selective amplifier (22), responsive to the peaked luminance signal, supplies its output to a peak detector (23). The control voltage developed by the peak detector adjusts the gain of the peaking signal translator (19) in a sense opposing amplitude variations of the detector input, providing compensatory gain variations when coring level changes effect residual peaking signal amplitude. <IMAGE>

Title: Measurement of distance using ultrasound
Inventor: REDDING ROBERT JAMES
IPC: G01S15/36
Filed: 1983-05-11
Abstract: Distance measuring apparatus comprises a carrier signal generator (5), an audio-frequency modulation signal generator (6, 8, 9) to generate a modulation signal having a frequency f, and a modulator (3) to frequency- modulate the carrier signal with the modulation signal. A transmitting transducer (1) is energizable by the frequency-modulated carrier signal to transmit ultrasound energy. A receiving transducer (2) is spaced from the first point by a distance which is to be measured, and receives at least part of the transmitted ultrasound energy. A phase comparator (11) monitors the phase relationship between the audio modulation received by the receiving transducer and the transmitted audio modulation, to give a first indication (14) of the measured distance. The modulation frequency can be changed, so that finer indications (16, 18) of the distance are provided. The modulation signal generator comprises transmitting and receiving transducers (6, 8) spaced apart by a reference distance (7) and a phase- lock loop (9) to adjust the generator frequency to maintain a constant phase relationship between the transmitted and received modulation signals. <IMAGE>

Title: Improvements in or relating to sample-and-hold circuits and methods
Inventor: LIE HANS PETER
IPC: G11C27/02
Filed: 1983-09-27
Abstract: A feedback sample and hold circuit has an amplifier A whose output is connected through a sampling switch (SS) to the input of a buffer (B). A holding capacitor (CH) is connected between input of the buffer (B) and ground potential. A correction coupling capacitor (CCC) and a correction holding capacitor (CCH) are connected between the input of the buffer (B) and ground. A correction switch SC is connected between amplifier output (14) and the common node (22) of the correction capacitors, (CCC, CCH).

The correction correction coupling capacitor (CCC) couples this correction in attenuated form to the holding capacitor (CH). An additional correction switch (SC2, Fig. 3) may be connected between the between the node 22 and ground. <IMAGE>

Abstract: A device for charging or discharging a member is arranged opposite to a member 2 to be charged or discharged, and comprises an inducing electrode 4 and a discharging electrode 5 sandwiching a dielectric member 3 so that the discharging electrode faces the member to be charged, and an alternating voltage is applied between the inducting electrode 4 and the discharging electrode 5 to produce a surface discharge on a surface of the dielectric member 3 at the discharage electrode side, wherein the charge density of the surface discharge area varies in the direction of the width of the discharging electrode; by moving the member 2 to be charged or discharged relative to the discharging electrode, it can be subjected first to a low charge density portion an then to a high charge density portion. The variation of charge density can be achieved by positioning the discharging electrode 5 nearer to one edge of the inducing electrode 4, on providing several discharging electrodes at varying spacings. <IMAGE>

Title: Method and apparatus for secondary fermentation of beverages
Inventor: THOMAS KEITH ROBERT
IPC: C12G1/073
Filed: 1984-06-29
Abstract: Where a beverage, e.g. beer, is pressurized in a dispensing vessel by secondary fermentation it is necessary to ensure that the yeast settles properly before the beverage is dispensed. This tends to restrict the usage of such beverage to places providing the required stable environment for settling to take place. A method is therefore provided in which the yeast is restrained, so that it cannot mix freely in the beverage but still has sufficient contact with the beverage for the fermentation to proceed. Such restraining can be achieved either by entrapping the yeast within a porous or partly porous container 3 immersed in the beverage or forming an integral part of the dispensing vessel, the porosity being such as to allow passage of the beverage but not the yeast particles, or by immobilising the yeast on a support material (23) free or fixed within the vessel (22). <IMAGE>

A discharge orifice (24) in the top wail of the cap is closed by the stopper plug (20) when the cap is screwed down on the body portion (12) under the action of screw threads (26, 28). The unscrewing movement of the cap causes it to be forcibly raised axially on the body portion (12) to open the orifice under the action of a follower lug (42) riding on a curved cam track (40). <IMAGE>

Title: A hydropneumatic vehicle suspension with load-responsive damping
Inventor: BECK HUBERT
IPC: F16F9/512
Filed: 1984-12-03
Abstract: A self-levelling hydropneumatic vehicle suspension is arranged to give an automatic increase in the damping of the vehicle on increase in the load and a reduction in the damping when the load on the vehicle is reduced. In addition to conventional damping valves (13, 16) a component has a bypass 14 of variable throttling cross-sectional area 23, 24. This component may be the damping piston 10 of the telescopic suspension strut, 5, or can be connected in the form of a separate component (Fig. 4) to the telescopic suspension strut 5. The fluid pressure in the system and external atmospheric pressure act on a control slide 20, axial displacement of which regulates the effective throttling cross-sectional area of the bypass. The displacement of the control slide 20 is in addition influenced by the spring force of the extension phase damping valve 16 which likewise assists in regulation of the damping in accordance with load. <IMAGE>
