Title: Coding and decoding of TV signals
IPC: H04N7/171
Filed: 1979-11-27
Abstract: A method of coding and decoding video signals includes suppressing synchronization pulses during the video horizontal and vertical blanking intervals by gates 16 and 22 and inserting clock and address information in the suppressed intervals by a line modulator (36) and an address gate (44) respectively. Digital sound information may be inserted in the suppressed horizontal blanking intervals by a gate (30). At the receiver the unsynchronized video and the clock information are detected by a video detector and the clock is used to control a sync pulse generator to provide the sync pulses which are then recombined with the unsynchronized video. The digital sound information is used to provide program audio which is then combined with the above-described video signal to provide a television signal useable in a receiver. <IMAGE>

Title: Counting sheets in a stream
IPC: G06M7/10
Filed: 1980-11-07
Abstract: For determining the number of sheets in a stream of sheets moving along on a conveyor or the like, for example from a folder to a stacker, the sheets are counted by measuring physical characteristics representative of the stream of sheets, for example the thickness and the speed thereof or the weight of the stream passing a certain location. Electric signals taken from such measurements of the stream are fed into a calculator which compares the measurements with standard measurements obtained from a single sheet to produce a value of the number of sheets passing that location in the stream. <IMAGE>

Title: I.C. engine fuel injection nozzles
IPC: F02M61/16
Filed: 1982-03-09
Abstract: A valve member is divided into two parts 17, 18 which are axially movable relative to each other. A mechanical connection 9 or an hydraulic connection, Figs. 2 and 3 (not shown), is provided to limit the extent of relative movement of the parts. Fuel from a fuel inlet passage 15 can act on the opposing surfaces of the parts, the effective areas of these surfaces being greater than the effective area of the surface of the one part which is shaped to co-operate with the valve seating 13.
