Patent GB-2066603-A (GB)
Title: Improvements in or relating to storing and reproducing analogue signals
IPC: G10L13/06
Filed: 1980-12-15
Abstract: An analogue signal, such as a speech signal, is encoded by a delta modulation encoder 3 and stored in a digital memory 5, or is decoded by a delta modulation decoder from the store 5. The speed at which the bits are produced by an encoder 3 and read into the memory 5 or read out of the store 5 and decoded by the decoder is controlled by the instantaneous value of a characteristic quantity of the analogue signal or the associated binary coded signal. The characteristic quantity may be the binary pattern which is produced by a limited number of successive bits of the encoded or read-out signal. It is thus possible to reduce the memory space required for a given length of signal to be reproduced with a given quality. <IMAGE>

Title: Calibrating instruments for counting and measuring particles
IPC: G01N15/10
Filed: 1981-03-19
Abstract: A method for calibration of instruments serving to count and to determine the size of particles suspended in a dispersion medium consists in setting a particle 12 of known size in a dispersion medium in motion so that it repeatedly crosses the sensing zone 8 of the instrument under calibration. Radiant energy, such as light, is passed through zone 8 to detector 5 which, due to the particle passing, gives pulses which are used as a basis to set the threshold of sensitivity of the instrument under calibration. An actuator 13 sets the particle 12 in motion in a dispersion medium in a vessel 10 which is placed in the sensing zone 8. Alternatively vessel 10 may be placed in the position of an enlarged image of zone 8. There may be another actuator at the top of vessel 10. <IMAGE>

Patent GB-2078329-A (GB)
Title: Indicating lack of clearance in clutch release mechanism
IPC: F16D13/58
Filed: 1981-06-09
Abstract: A vehicle clutch, when engaged, should have a predetermined clearance between its release bearing 11 and its release plate 10. To disengage the clutch, a release bearing carrier sleeve 12 is slideable to cause the bearing to contact the plate and then displace it axially. To indicate deleterious lack of clearance, the bearing has an electrically-insulating mounting 13, 15 and is connected to the vehicle's electric supply 18 by a power line 16 containing warning light 19. The plate 10 is inherently connected electrically to the vehicle's chassis, and the bearing thus acts as a switch. To prevent the light being illuminated when normal operation of the clutch occurs, the power line also contains an automatic electronic delay circuit. <IMAGE>
