Title: Pressure vessel valve unit - has outlet and actuating boss integral with cap and of injection moulded plastics
Inventor: WITTERSHEIM ADAM
IPC: B65D83/14

Title: High efficiency heat engine - with gas and steam of different k-factors as working medium (SW 13.3.78)
Inventor: ABOM JAN VIKTOR
IPC: F01K21/04
Filed: 1977-11-15
Abstract: Mechanical power is developed in a heat engine which uses as the working medium a gas to which a vapour with a lower ratio of the specific heats at constant pressure and at constant volume (k-factor) than that of the gas is added. The pref. gas is argon or helium (k=1.66) and the preferred vapour is steam (k=1.30). The gas is made to absorb the heat of condensation of the steam by condensation in isothermal expansion. The efficiency of the engine is raised thereby to 75%, compared with max. 37% in the Sterling or Diesel processes.

Title: Mfg. heavy-duty cord-reinforced long rubber pipe for underwater use - using machine having automatic control for speed of throughput, application of strengthening plies and vulcanisation
Inventor: GRUBER KURT DR ING
IPC: B29D23/00
Filed: 1978-04-12
Abstract: Device for mfr. of fibre- or steel wire-reinforced rubber pipes having a dia. exceeding 200mm and length over 100m and whose core, filled with a pressurised liq., is alternatingly coated with rubber and fibre- or steel wire cords and subsequently interiorly and exteriorly vulcanised, is claimed. A stationary, hydraulic, installation is used which both provides hot pressure oil for the core in order to stiffen it transversely preparatory to winding-about and application of the rubber layers under relatively low pressure, and also to test the prod. under high pressure, after the vulcanisation step. Between those two steps, pressure oil is fed to the oil engines for driving and transverse conveyance of the winding reels and for automatic throughput control for the pipe as they pass between the reels. Used for mfr. of heavy-duty pipes for deep-sea applications.
Patent DE-2816117-A1 (DE)
Title: Hydraulic ingot mould stripper mechanism - with intermediate piece for self-aligning clearance
Inventor: KROPIK ERNST
IPC: B22D29/06
Filed: 1978-04-14
Abstract: Hydraulic stripper mechanism has a ball-and-socket joint between the stripper plunger and the piston rod. An intermediate piece links the hydraulic cylinder to the plunger in such a way that in the OFF position a slight clearance is maintained between the piston rod end and the joint. This allows a self-alignment of the plunger and prevents the frequent premature failures of the hydraulic cylinder seals. A trunk, attached to the hydraulic cylinder, carries the lifting jaws for the ingot mould with the ingot. The stripper plunger is fitted on top with a ball-and-socket joint.

Title: Agricultural machine for ground working and narrowing - levels furrowed ground by exchange and disintegration of soil subsequently compacted
IPC: A01B79/00
Filed: 1978-04-26
Abstract: The agricultural machine is used for soil working. The ground or coarser lumps are at first cut up and subsequently disintegrated and mixed. The ground is also levelled in this process. The ground with furrows is levelled before cutting up and disintegration. At first the upper ground layer is disintegrated and compacted and subsequently the still coarser lumps are lifted upwards in exchange for the downwards flowing disintegrated particles. These lumps are also disintegrated and compacted. All these operations are carried out in a single training agricultural implement.

Title: Infectious sewage sterilisation - by anodic oxidation following mechanical and biological treatment
Inventor: SCHOEBERL MEINOLF DIPL ING
IPC: C02F1/70
Filed: 1978-05-18
Abstract: Infectious hospital and municipal sewage is disinfected and sterilized by passing through a mechanical and biological cleaning stage, followed by filtering. Any microorganism including any virous infections are then inactivated by anodic oxidation in an electrochemical reactor, with a final reduction stage, if necessary. This achieves a sterilisation rate of 99.9% in 5 secs., compared with a rate of 99.7% in 7 minutes for conventional systems. The result is a reduction in operating cost.

Title: Toothpick having thin flexible rounded metal strip - esp. of copper, silver, or gold, perpendicular to handle
Inventor: DOLINSKY JOSEF DR
IPC: A61C15/02
Filed: 1978-09-29
Abstract: Tooth pick consists of a handle with a head piece at an angle from 90 - 135 degrees. A transition piece which can be plugged into the head piece is tapered down from a 4 x 2 mm section at the junction to 3 x 1 mm at the other end. It continues in a metal spring which is made of silver or gold in the de luxe version and of copper in the ordinary version. This tapers to a section of 2 x 0.1 mm with a large radius at the end. The blunt shape prevents damage to the gums. The action is more efficient than a conventional toothpick or a pin which often just jams the food remnants more tightly into the gap between the teeth.
Patent DE-2843410-A1 (DE)
Title: Shift register control for video signal generation - samples photodetectors for storage in register using clock control to avoid interference signal effects
Inventor: WOELBER JOERG ING GRAD
IPC: G11C27/04
Filed: 1978-10-05
Abstract: A shift register used in a video signal generation system operates to a clock cycle that eliminates the possibility of distortion effects. The shift register has e.g. 256 memory cells, with data being moved from the left to the right. The output stage (8) transmits signals serially to an output stage (12) for amplification before transmission. A reset facility (14) allows the stage to be cleared after a specified interval. In parallel with the shift register cells are a similar number of photo detector cells (P256-P1) that are sampled within a given period and the charges entered into the register. The signal transfers take place under control of clock signals (4, 5, 6) to form a video signal. The clock signals are phased to prevent the occurrence of disturbances between successive video signals.
