Title: Switch=off spot suppression for TV receiver - applying flyback pulses and disabling voltage to luminance electrode
Inventor: POLLAK ALFRED
IPC: H04N3/20
Filed: 1979-03-15
Abstract: The dark-level control applies flyback pulses to the luminance electrode of the picture tube for flyback blanking and applies a disabling voltage to the same electrode for blanking out. The flyback pulses (14) are applied via an RC circuit (8) to the control electrode (13) which is connected via a diode (12) to a second supply voltage (d) or to ground. The diode is reverse biased w.r.t. the flyback pulses. The flyback pulses are raised to the level of a first supply voltage (a) which is also the supply voltage for the line output stage (2-5). The flyback pulses are clamped to the first supply voltage via a capacitor (6) and a diode (7). The RC circuit's (8) input is grounded via a resistor (10).

Title: Multistation reaction injection moulding appts. - in which each station is fed with components via a supply and a return manifold
Inventor: TILGNER PETER JOACHIM
IPC: B29C44/38
Filed: 1979-03-27
Abstract: In apparatus for reaction injection plastics material at separate stations, each of the components is fed from a source along a supply manifold and back to the source via a return manifold. Each station has a mixer/injector head connected via feed and return shunt lines to the supply and return manifolds. First valves are provided to stop circulation in the manifolds and second valves are provided to prevent circulation of components from the manifolds to the heads. In use, to effect injection with a chosen head the first valves are closed to prevent manifold recirculation and the second valves of all the heads except the chosen one are closed. This causes the components to flow along the supply manifold and down the shunt line of the chosen head for dispensing. The arrangement is of particular use in injecting foamed resin, e.g. polyurethane, into refrigerator cabinets fed from a main conveyor to positions beneath the heads. One or more heads can be used at the same time.

Title: Frozen food cutting press chamber - with U=shaped walls joined by seams welded along short sides
Inventor: GROSS ERNST PETER ING GRAD
IPC: A22C25/20
Filed: 1979-05-18
Abstract: A press chamber in a welded design for cutter presses in the food industry, specially for cutting frozen fish meat is a rectangular cavity which guides a piston for heavy-duty loading. The chamber walls have been machined from the solid to a U-shaped and are joined to each other by welds along the centre of the short sides of the rectangle. Strong ribs lengthwise and crosswise reinforce the chamber. This removes the welds from the corners of conventional press chambers where experience has shown the existance of weak points leading to premature failure.

Title: Telephone circuit connection selection - has auxiliary information channel, with narrow band frequency response and is active before called subscriber answers
Inventor: GYALISTRAS DIONYSIOS DR ING
IPC: H04M11/00
Filed: 1979-09-12
Abstract: The equipment is intended to assist in preventing incorrect connections. In the final line selection equipment (LW) between the calling subscriber (T1) and the called number (T2) is a narrow band filter (Y). This filter is in circuit between the two subscribers as soon as the complete route has been selected and before the called subscriber answers. Through this narrow band channel information signals can be passed, superimposed on the ringing circuit. These information signals operate in conjunction with receivers and transmitters (S,H) on the subscriber instruments, and can be used to check, for example, that the correct number is ringing out. They can also be used to record call back requests or similar functions.

Title: Double-acting slip-ring seal - has elastic seal thrust axially against slip-ring stop by pressure difference
Inventor: ETOLA ERKKI DIPL ING
IPC: F16J15/40
Filed: 1980-03-05
Abstract: The double-acting slipring-type seal comprises a ring fixed to and rotating with a shaft and a slipring sliding axially but not turning in a housing enclosing and clear of the shaft. Its surface is thrust against that of the shaft ring both by the medium to be sealed off and the pressure of the barrier fluid. The housing has a face against which an elastic seal for the gap between it and the slipring in the radial direction is thrust axially and the slipring has a stop opposite this housing face. The elastic seal is thrust axially by the resultant of the pressure difference between the barrier fluid and the medium to be sealed off against the stop on the slipring and in the direction of the shaft ring.

Title: Inductive changeover control for steam engine - generates inductive field at start and end of camshaft-less engine cylinder, whose piston changes inductive field
Inventor: KRESEL ROLF
IPC: F01L25/08
Filed: 1980-04-24
Abstract: At the beginning and end of a working stroke in the steam engine cylinder an induction field is generated. On attaining its end position, the steam engine piston changes the induction field and thus also the control current for the change-over control device. Analogously this control device can be regulated by a compressor piston. The system is intended for a steam engine in which its piston is coupled to the piston of a refrigerator compressor, in which case the engine can be operated not only by steam, but also by coolant vapours. The change-over control of the engine piston can be carried out by rotary or linear sliders, or by a control valve system. A coil for generation of an induction field is mounted at both end points of the engine cylinder, and the piston movement changes the induction field and thus the control current for change-over of an incorporated relay.

Title: Quenching of hot coke using crude gas aq. condensate - with prodn. of water gas and destruction of condensate impurities
Inventor: STRUCK CARL-HEINZ DIPL CHEM DR
IPC: C10B39/04
Filed: 1980-07-26
Abstract: Hot coke at about 1000 deg.C is quenched by passing down a tower, where (at 400-600 deg.C) it meets a spray of crude gas cooler condensate (gas water) (I) and then (at 200-300 deg.C) a spray of relatively pure work water (II). The gas leaving the reactor top, contg. water vapour and water gas is partially combusted to about 1000 deg.C. It may then be passed to a catalytic reactor to destroy the remains of the HN3, HCN and phenols, which were present in (I). Some of the water gas may be recycled to the base of the quench reactor to improve heat transfer. The water leaves the bottom of the reactor at approx. 100 deg.C. The net energy recovered per tonne of coke is 339,000 kcal, vs. 170000 in conventional quenching, and is largely in the form of water gas. Contaminants in (I) are almost fully destroyed without harmful emissions. The coke prod. has no smell.
