Patent DE-2362765-A1 (DE)
Title: Radio remote control - designed for large number of independent devices through common HF channel and command generators
Inventor: DIZIOL KLAUS DIPL ING
IPC: B66C13/44
Filed: 1973-12-17
Abstract: The invention increases the number of large machines or complicated apparatus that can be independently controlled by a single h.f. channel. Induction or other mutual interferences are removed. The command generators are permanently allocated to the devices or command receivers. They consist of a sender and a control receiver, which controls signal transmission in accordance with received signals from other senders. A certain position in a time pattern is allocated by a specified address to each sender and the corresponding control and command receivers. The address is transmitted with each radio telegram. All senders are synchronised with the time pattern by a crystal clock in the corresponding control receiver.

Title: Anti-static absorbent material for records - is incorporated in record jackets for anti-static impregnating agents
Inventor: MACK GEB DUSANEK HELGA
IPC: G11B33/04
Filed: 1974-01-22
Abstract: Strips of soft absorbent, resilient material are fixed near the opening of the second jacket to both inner sides and parallel to the edge of the opening. The material absorbs the impregnating agents, so that any dirt or dust sticking to the record is removed, when the record is removed from or returned to the second jacket. At the same time the surface of the record is provided with the impregnating agent from the material. Alternatively, the whole area of the inside of the record jacket is completely covered with a soft, absorbent, resilient material containing the impregnating agents.

Title: Production of quarz single crystals - having seed crystal plates inclined to the vertical to avoid particle inclusions
Inventor: BUTUSOW WLADIMIR PETROWITSCH
IPC: C30B7/10
Filed: 1974-01-31
Abstract: Synthetic angle crystals, esp. of quartz for radiation and optical appts. are produced from hydrothermal solns. under pressure in an autoclave using the temp. drop process. The seed crystal plates are orientated to the gravity axis at an angle 45-90 degrees. The upper surfaces of the plates are protected by a plate of inert material which causes the growth to be preferentially on the lower side of the plate. It can even be arranged that the protective plate is so dimensioned that no growth whatever occurs on the upper surface. The method produces crystals on the lower growth surface with =10 structural faults per cm2.

Title: Transport and turning device for edged material - can bring two bars simultaneously into machining position on lifting table
Inventor: AENGENEYNDT WOLF DIPL ING
IPC: B21B39/22
Filed: 1974-07-26
Abstract: Transport and timing device for edged material, all of whose sides must once lie upwards e.g. for rod treatment in rolling mills when surface faults must be controlled and eliminated by grinding. A system, made up of a delivery, timing and lifting device brings the bars simultaneously into a machining position on a lifting table. It captures them by lowering the table in pivot levers and turns through 90 deg. At each second turn the system is moved forwards by a step so that on lowering the rod which has been machined on all sides, this carried away. Simultaneously a new bar is fed to the opposite side. The table is so hinged in its lifting motion that it does not disrupt the feed on one hand and on the other hand carries the bars above the feed system as close as possible to the machinist.

Title: Refuse handling and preparation system - has centripetal air separator for production of heavy and light fractions before drying and fine comminution processes
Inventor: SCHAEFER K A R
IPC: C04B18/30
Filed: 1975-02-27
Abstract: The system for handling refuse or garbage, typically domestic rubbish, is constructed such that the refuse passes through a centripetal air separator (5), where it is split into a heavy fraction and a light fraction before passing into the fine comminuting (14) and drying (12) stages. The garbage separation of the heavy fraction includes a slinger/roller air separator and a magnetic belt. Stems such as bottles, sticks and stones are converted to a truck (11).

Patent DE-2520427-A1 (DE)
Title: Anticorrosion protection of industrial or drinking water pipes - by magnesium hydroxide gel from extraneous current applied to magnesium anode
Inventor: HERRE ERHARD DR
IPC: C23F13/02
Filed: 1975-05-07
Abstract: A protective anti-corrosion layer in pipes and fittings used in industrial and drinking water systems is produced by passing the water through a tank with a magnesium anode. An extraneous current supply, connected to the anode, produces a magnesium hydroxide gel which becomes deposited on the inner walls of the following galvanised iron or copper pipes. Magnesium is always present in water; it avoids the undesirable presence of aluminium ions, caused by aluminium anodes. Zinc ions are also undesirable in drinking water. The new system protects copper pipes where even phosphatising does not prevent corrosion.
