Title: Video signal storage system - uses half frame signals stored during first half period with second half frame period signals obtained by interpolation
Inventor: HEITMANN JUERGEN DIPL ING
IPC: H04N5/93
Filed: 1979-05-25
Abstract: The system is intended to reduce the vertical image fluctuations, even at lower alternating frequencies of the image content. Signals belonging to a half frame are taken from a signal source and stored during a first half frame period. The signals for a second half frame period are obtained, as known, by interpolation of signals of two sequential lines of the first half frame, these signals for the second half frame period then being stored. The signals from the source (8) are on one hand directly supplied to an input of an adding circuit (10), and on the other hand are supplied to another input of this circuit with a one line period delay. The adding circuit output signals with a half amplitude and the delayed signals are each coupled to an input of a change-over switch, controlled at a half vertical frequency. For reproduction of colour TV signals the low frequency components of two sequential lines may be interpolated and reproduced during the second half frame.
Patent DE-2924128-A1 (DE)
Title: Diesel engine using different fuel for starting and running - has single injector delivering starting and running fuel in sequence
Inventor: DIETRICH WERNER DR
IPC: F02M43/04
Filed: 1979-06-15
Abstract: A low pressure pump (1) delivers diesel fuel to an injector (4). The fuel collects in a chamber (10) in the base of the injector, but it is not at a high enough pressure to open the injector needle (11) against its spring. A high pressure injection pump (5) delivers alcohol to the same injector. This enters the same chamber and is at a high enough pressure to open the needle valve. As the diesel fuel is collected first it is at the lower part of the chamber and is therefore injected first. The injector enables an existing engine to be converted to run on a mixture of fuels, i.e. a starting fuel and a normal run fuel.
Patent DE-2926437-A1 (DE)
Title: Protective circuit for thyristor-switched couplings stages - uses closed loop operational amplifier earthing speech current fluctuations
Inventor: CAMPENAERE JOHAN DE
IPC: H04Q3/52
Filed: 1979-06-29
Abstract: In solid state switching of communication paths, thyristors are often used. Once switched on by a selector pulse the thyristor passes a current to act as a low resistance coupling link. Not infrequently spurious disturbances occur on the line which draw a current which opposes the maintaining current of the thyristor. The thyristor loses its conductivity and the connection already established breaks down at this point. To forestall this, diodes (D1 to D8) are provided in serial pairs and placed across the transformer windings (W2,W3) limiting peak to peak voltages to 1.4 volts. Current limitation is achieved by a variable ground resistance circuit consisting of an operational amplifier (OV) having a resistor (R) in the return loop from output to inverting input. For speech current fluctuations, this circuit constitutes a plain ground connection. The effective resistance for larger currents depends on the loop resistor (R).
Patent DE-2930080-A1 (DE)
Title: Excess spray material recovery unit - uses continuous honeycomb belt moving behind work pieces
Inventor: QUANDEL SIEGFRIED
IPC: B05B14/41
Filed: 1979-07-25
Abstract: The process is for the recovery of spray material, which is lost by overspray during spray coating of working pieces in spray booth. A continuous belt (6) moves behind the work pieces (4), catches the spray material which passes the work pieces, and feeds it to a rinsing system. The belt is honeycomb-shaped, and consists of relatively movable members of flat material, which allows an easy deflection. The members are air-permeable, and prevent air built-up. The narrow sides of the honeycombs attract the electrostatic particles, while the wide sides, together with their relative movement in relation to the spray jet, give rise to a wiping catching action.

Title: Semi-continuous pressurised gasification of coal - using detachable reactors charged and emptied of slag at ambient pressure
Inventor: HACKLER ERICH
IPC: C10J3/02
Filed: 1979-11-10
Abstract: Process and appts are claimed for the high-temp., high pressure gasification of coal or other hydrocarbon-contg material by reaction with a mixt of O2 and/or air with H2O and/or CO2. The feedstock is charged to a reactor at atmospheric pressure, which is then connected to a manifold and pressurised. After gasification is complete, the reactor is disconnected and depressurised and the residue, e.g. liquid slag, is discharged. Several reactors, if necessary transportable, may be connected to the same manifold. The exit line from the manifold may contain a reactor for a second stage of gasification, followed by another for gas purification. The discontinuous filling and emptying of the reactors avoids the difficulty of doing the same operation under pressure; yet the supply of prod gas from the manifold can be continuous.
