Title: Coded binary signals transmission method - between stations of wide radio network, uses addresses of respective called station
Inventor: HEROLD WOLF DIPL ING
IPC: H04W88/02
Filed: 1971-05-08
Abstract: Signals for a called station are transmitted in a given transmission band, using the called station address consisting of a series of binary signals with a higher pulse repetition frequency that that of the transmitted signal. This address is additively superposed on the addresses of other stations, and the called station recovers the information from the received signal by superposition of the synchronised address. A number of frequency bands is provided for the signal transmission, smaller than that of the stations; when receiving stations are idle, they automatically tune themselves to a frequency band with highest signal-to-noise ratio; when a station is called, it sends back its own address and a signal indicating the frequency band to which it is tuned; the transmitter uses this band for its reply.

Title: Automatic moisture control for ovens - by time switch and current control of steam generator
Inventor: LEPPER WILHELM DR ING
IPC: A21B3/04
Filed: 1972-09-18
Abstract: In the parent patent the moisture content of the air in the oven of an electric cooker is regulated by providing a water tank with a steam generating heater or with a metering device for vaporising attachments.

Title: Withdrawal device for arcuate path continuous casting machines - having upper roll yoke mounted on guide columns
Inventor: BOLLIG GEORG DIPL ING
IPC: B22D11/12
Filed: 1972-12-30
Abstract: Sets of upper rolls are mounted in pivoted yokes which extend transversely w.r.t. the casting pass line and are guided at both ends by guide columns. The foot of each column is connected to the base frame of the device by bolts which are parallel to the roll axes and determine the path of the casting through the device. This arrangement is less expensive and more stable than the prior art arrangement using U-shaped guide blocks, and use of bolts obviates provision of accurate mating faces between the guides and the base frame.

Title: Protection circuit for TDM transmission - uses second number of time slots for block repetition in case of interference
Inventor: PROEGLER MAX DIPL ING
IPC: H04L1/00
Filed: 1973-06-13
Abstract: The protection circuit is for data transmitted in duplex in communication systems. It uses a TDM channel for alternate transmission in both directions with equal transmission periods. A redundant testing code and tolerance detectors are used for error detection and correction. They initiate repetition of signal parts which cannot be corrected. Several time slots allocated to one transmission direction form a common frame. A first number of time slots is used for transmission of a data block each at an increased bit rate, and a second number of time slots is used for block repetition in case of interference.

Title: Drive system for vehicles of all types - has gravitation motor adjustable to earths axis thus moving the vehicle in any desired direction
IPC: F03G7/00
Filed: 1973-07-03
Abstract: The gravitation motor flow chamber as in 319880, is connected with a closed liquid circuit maintained by one or more electrically operated pumps driven by batteries recharged by solar cells, or by an inbuilt atomic reactor which works by restricting and dividing at its equator. The gravitation motor could be fixed to the helmet of a space suit with the solar cells formed as retractable wings. The gravitation motor axis internal flow is adjusted relative to the earths axis so that the vehicle will be drawn or repelled or moved in a horizontal direction as desired. The internal flow is maintained by simply overcoming the slight friction loss in the flow by a continuous revolving throttle valve arranged in the flow pipes to compel a periodic sine wave.

Title: High frequency connection lead-ins - for crystal pulling furnace sealed by grooved sockets and O-rings
Inventor: MEIER PETER
IPC: H01B17/30
Filed: 1973-10-03
Abstract: An HF crystal pulling furnace with a high-pressure pulling chamber has a cover, designed as a dome, through which the pull rod of the crystal holder is passed in a seal. In the patent of addtn. a cylindrical metal socket is sealed pressure-tight against the bottom of the pulling chamber of surround the lead-in and lead-out tubes of the HF terminals in the cover. The inside surface of the socket surrounds. with a pressure-tight seal a cylindrical insulator which in turn encloses the lead-in and lead-out tubes with a pressure-tight seal. This eliminates the necessity of the very delicate brazed joint between the lead-in and lead-out tubes and the copper-plated intermediate pieces of stainless steel. Differential thermal expansion destroys these joints and this possible source of trouble is eliminated.

Title: Injection anchor with tensile members - incorporates a tubular member for later crushing of anchor for releasing purposes
IPC: E02D5/76
Filed: 1973-11-09
Abstract: The injection anchor holds a number of tension members and this anchor is used for making a permanent structure as support for an embankment wall. These anchors can also be used for temporary support such as excavation walls for building work. In this instance it may be necessary to move the anchor into adjacent areas and these anchors may have to be removed because they form obstruction for further building work. The anchor system clamps tension members which are arranged around the central tube, which can be made from plastics, and its purpose is to admit cutting tools for destruction of the embedding material which can be injected cement mortar or epoxy resin mortar. The central tube may have a rubber sleeve at intervals.

Patent DE-2360293-A1 (DE)
Title: Emergency cooling system - for nuclear reactor based on shunt permanently across secondary coolant circuit
Inventor: VIEIDER GOTTFRIED
IPC: G21C15/18
Filed: 1973-12-04
Abstract: The shunt circuit contains a thermal energy store in the form of a buffer boiler across the main steam lines from the steam generator heat exchanger in the pressure vessel, through which the primary coolant from the core proper is circulated by mains driven pump system; coupled to the same shaft are auxiliary motors whose power is derived from an auxiliary alternator driven by the low pressure turbine following the H.P. turbine in the auxiliary steam loop. This H.P. turbine drives one pump to force the continued circulation of secondary coolant through the main heat exchangers and a second pump forcing external cooling water through the condenser/cooler heat exchanger in the secondary loop which follows the L.P. turbine. As soon as the mains fail, the main steam lines to the station turbine are shut off by automatic valves, so ensuring the isolation of the secondary emergency cooling system from external influences or losses.

Title: Assembly system for two clock parts - one part has projecting legs to lock in holes in other part
IPC: G04B29/04
Filed: 1974-02-28
Abstract: The clock part provided with the holes is made with a resilient tongue at one side of the hole, so that this can be pushed aside to allow the insertion of the leg projecting from the other part. The leg has a foot which locates underneath the first clock part when the two parts are assembled to lock them together, and which also serves to deflect the resilient tongue during insertion of the leg. The system may be used to attach figures to the wall of an alarm clock housing.
