Title: Converter for radiograph closed cct. signals - changes to binary quantity picture signals using limiter amplifier
Inventor: WIECHMANN HANS DIPL ING
IPC: H04N5/32
Filed: 1974-08-26
Abstract: The presentation of silhouettes of organs, e.g. of the heart for evaluating its form and diagnostic changes, is made possible by the binary quantity picture signals. A limiter amplifier is used in conjunction with a regulating circuit for automatic application of the clamping level. The regulating circuit uses contour signals produced from the radiograph closed circuit picture signals and instability signals produced from the clipping signals of the limiter amplifier. At the output of the contour comparator a positive and a negative square wave impulse for every contour is produced. These comparative signals are fed to an integrator whose charge voltage is varied by the difference in duration of the impulses. The charge voltage serves as regulating potential for the limiter amplifier.

Title: Cellular safety structure for tanker - with plastic covered honeycomb in different gas pressure sections
Inventor: HANSCHMANN HORST
IPC: B64B1/58
Filed: 1974-08-30
Abstract: The cellular safety structure is made on a large dimension press which prepares the separate layers of the honeycomb. The press also coats both sides of the wall with resin or glass fibre for a smooth finish. Connecting holes are pressed in at the same time so that as the honeycomb is assembled it can be subdivided into separate section, each fitted with separate valves. The sections are filled with gases at different pressures, or are evacuated. Around the engine room of the tanker the structure is designed to be progressively more fireproof. Any damage in the honeycomb is readily detected by ultrasonic means and plastic liquid resin can be introduced into the damaged sections to seal the leaks.

Title: Doppler head reciprocal movement system - has series of contra rotating circular loci centred on moving centre circle
Inventor: PRICHODJKO ALEXANDER
IPC: F16H35/00
Filed: 1975-06-14
Abstract: The method of achieving reciprocating movement is particularly intended for use in Poppler head movement systems. The design overcomes the need for braking and acceleration at the end point of the travel. The equipment is moved along a primary circular locus with radius R at a prescribed angular velocity and direction of movement. At the same time the mid point of the primary circle is itself moving round a second circle with the same radius and at the same angular speed but in the opposite direction of rotation. The reversal of direction at the end point of translational movement occurs where the resultant momentary speed is nil.
Patent DE-2530550-A1 (DE)
Title: Filter press system with pressure vessel - having fixed delivery pump and air cushion in vessel to discharge press
Inventor: HAECKER KARL
IPC: B01D25/00
Filed: 1975-07-09
Abstract: Process for filtering involves feeding a slurry to a filter press by means of a pump with onstant or controllable delivery. On the opposite side of the plate bundle to the input line either directly on the end plate or with a line, there is connected a storage vessel. This can hold slurry under pressure and release it when the delivery pump is stopped. The periodic inflow and outflow of slurry from this vessel prevents the inlet to the press from blocking. The vessel acts as an air receiver. The air cushion in it is increased by compressed air and for optimal use of this, a level control is included. When the press is fully charged, as indicated by the pressure which the delivery pump has reached, residual slurry is blown back to the holding vessel by the air cushion. For use with filter press systems. Has the advantage of preventing the deposition of a cake prematurely in the channel of the press, thus extending the effective life of the press. Allows the inlet passage to be blown free on completion of the filter cycle.

Title: Television receiver line output stabiliser - employs mains voltage fluctuations to control transductor inductance
Inventor: SCHUBERT RUDOLF DIPL ING
IPC: H03K4/62
Filed: 1975-09-06
Abstract: The circuit is for the stabilisation of the line output stage in a television receiver which does not introduce appreciable loss of power or available working voltage, whilst providing freedom from the effects of a fluctuating power supply voltage. A control signal derived from the mains voltage controls the line output stage to give constant deflection amplitude and EHT, and also controls the control winding of a transductor (14) so that with increasing supply voltage the inductance of the working winding (13) increases. The dc voltage (U2) is greater than the operating voltage (U1).

Title: Rope or twine twisting and winding unit - has a sliding press passing through two rotating drum sections for simultaneous operation
Inventor: BECK ARNOLD
IPC: D01H1/08
Filed: 1975-12-02
Abstract: The unit is partic. for ropes and binder twine, and uses a rotating drum and a sliding guide to lay the yarn in spirals against the inner wall of the drum. The drum is composed of two separately powered sections which are rotated at a greater speed than the feed speed of the yarn. A press die matching the diameter of the drum halves, slides axially through the drum sections. The design gives a simultaneous twisting and winding action on the yarn, in a simply constructed equipment, giving a continuous operation following the drawing phase. The higher speed of the rotating drum imparts the require twisting action on the yarn.

Title: Removing hydrogen sulphide from coke oven gas - by treating with recycled ammonia water in which the hot ammonia water is stripped through purified gas fraction
Inventor: BURKERT RUDOLF DIPL ING
IPC: B01D53/14
Filed: 1975-12-24
Abstract: Hydrogen sulphide is removed from coke oven gas by using recycled ammonia-water in which NH3 contg. gas is fed to the H2S scrubber, the regenerated hot ammonia-water being stripped through purified coke oven gas and the thus NH3 enriched gas is passed to an intermediate and/or final wash stage of the H2S washer. A fraction of the treated coke oven gas taken from the delivery side of the suction unit serves as purified gas and the H2S washer is located on the suction side of the gas stream. Process does not require a supply of high purity ammonia to the final wash stage, which involves high heat and vapour consumption, and is thus more economical.
