Patent DE-3036205-A1 (DE)
Title: Digital data transmission between exchange and terminal - using rising edge of each logic one pulse for synchronising terminal with exchange
Inventor: BLOSSFELDT DIETER DIPL ING
IPC: H04Q11/04
Filed: 1980-09-25
Abstract: The application is to a telephone and digital data transmission link between an exchange (ZSt) and a data and telephone terminal or receiver (TS1). Connection is by four cores, two (a1,b1) for telephone and two (c1,d1) for data. The terminal receives digital pulses by voltage modulation and transmits by current modulation, the two transmissions being interleaved. In order to keep the terminal oscillator (Osz2) synchronised with that (Osz1) of the exchange use is made of the pulses coming into the terminal. Each rising, or positive going, edge is used as a synchronising mark. As these occur very frequently in a data block the terminal synchronisation is sufficiently accurate to govern its transmissions. It enables the use of a less costly oscillator at the terminal than at the exchange.

Title: Device for raising and securing the feet of animals
IPC: A01L13/00
Filed: 1981-04-13
Abstract: For a winch for raising and securing the feet of animals during claw treatment in so-called grooming booths, provision is made to permit lowering of the winch without reversing the direction of rotation of the winch lever. Serving this purpose is a construction in which the rope drum (2, 13) designed as hollow shaft (2) is firmly connected to a winch shaft (3) mounted on the frame tube (1), and both parts (2, 3) can be released together by axial displacement from the ratchet mechanism (pawl 10, ratchet wheel 7) by means of the winch lever (9) and against the force of a compression spring (5) located in the shaft interior (2a). In this unlocked state, the rope drum (2, 13) rotates under load together with the winch shaft (3) in direction P4, in the course of which the lowering speed can be regulated by more or less pronounced applied pressure of one of the rope pulleys by means of the hand lever (9) against a brake block (16) fastened to the frame tube (1). <IMAGE>

Title: Method for determining gun sites
Inventor: MEUSER WILFRIED DIPL ING
IPC: G01S5/22
Filed: 1981-04-27
Abstract: The invention relates to a method for locating the airborne sound of blasts. It is known to use individual microphones at measuring locations, the distances of which are within the kilometre range, for determining the sites of guns. Transit time differences of the blast between in each case two measuring locations provide hyperbola, the point of intersection of which identify the gun site. Analysers must correlate blast patterns with the sound events and find identical reference points within the blast pattern in order to determine transit time differences between the blast patterns. Weather influences and different propagation paths of the blast make their determination more difficult. This problem is solved by using in each case one cross of four closely adjacent microphones at two measuring locations, the one axis of which cross points in one reference direction. Transit times between diametrically opposite microphones are placed in a ratio, the arc tangent of which specifies the bearing angle to the reference direction. From the two bearing angles, the gun site is determined, taking into consideration the position of the measuring locations. This method provides for artillery reconnaissance even under unfavourable weather conditions.

Title: Optical glass of high refractive index and improved transmission
Inventor: VOGEL WERNER PROF DR DIPL CHEM
IPC: C03C3/16
Filed: 1981-06-27
Abstract: The invention relates to glasses of high optical refractive index and improved transmission in the short-wave part of the VIS spectral region and variable dispersion. The object is achieved according to the invention by phosphotellurite glasses produced from 96 to 2 mol % TeO2, 2 to 49 mol % of P2O5 and 2 to 49 mol % of PbO and/or ZnO. In order to vary the properties, it is possible additionally to introduce into the melt up to 10 mol % of MgO, up to 47 mol % of CaO, SrO and BaO and up to 5 mol % of B2O3 or La2O3, up to 7 mol % of Bi2O3, up to 3 mol % of Nb2O5 and up to 2 mol % of TiO2. The oxides can also be added to the melt mixture in the form of their metaphosphates. In order to produce a sufficient oxidation potential in the glass melt which is necessary for good transmission of the glasses, addition of from 0.1 to 5 % by weight of As2O3 or CeO2 to the melt mixture beyond the 100 % mixture composition is necessary. The most advantageous glasses with respect to their optical and chemical properties are produced from mixture compositions in the immediate vicinity of the metaphosphate-tellurium dioxide composition lines. The glasses can be produced by conventional processes in gold crucibles using a gold stirrer.

Patent DE-3129677-A1 (DE)
Title: Safety circuit for an absorption heat pump
Inventor: POEHLMANN ERICH
IPC: F25B47/02
Filed: 1981-07-28
Abstract: In defrosting the evaporator in an absorption heat-pump circuit by means of hot gas, the risk exists that the boiler heats dry and is thus overheated. This is essentially brought about by the jerk-like lowering of the pressure in the absorber on completion of the defrosting process to the usual evaporation pressure, while during the defrosting process a higher evaporation pressure prevailed in the absorber. The pressure drop brings about an outgassing of the coolant mixture and thus an at least partial rendering ineffective of the solvent pump between absorber and boiler. As a result of the creation of this liquid/gas mixture in the absorber, there is a level rise and this can be monitored by means of a level-monitoring device with an electrode in the absorber, which in the event of need switches a solenoid valve in a bypass to bridge the condenser and the evaporator in the absorption heat-pump circuit. If appropriate, it can additionally act directly on the heating of the boiler. <IMAGE>
Patent DE-3143534-A1 (DE)
Title: Continuously running absorption refrigeration unit without a refrigerant distillation process
Inventor: RIEDER JOACHIM
IPC: F25B15/14
Filed: 1981-11-03
Abstract: The principle of continuously running absorption refrigeration units has been known for about 125 years. The major drawback of these units is the very low efficiency. With this principle, the energy which must be supplied is almost twice the refrigeration output generated. The reason is that the refrigerant distillation process in the stripper/condenser unit naturally requires at least the same energy consumption as the subsequent vaporisation of the refrigerant for the actual generation of cold. According to the invention, this refrigerant distillation process is replaced by reverse osmosis, so that the absorption refrigeration unit runs substantially more economically.

IPC: C02F1/42
Filed: 1982-03-16
Abstract: In order to match the consumption of brine required for regeneration of the ion exchange packing to the local degree of water hardness and thus to the degree of exhaustion of the ion exchange packing, a water storage container (4) is provided above the salt container in a water softening device. The quantity of water serving to introduce the required amount of brine from the salt container into the ion exchange container is stored in the water storage container from the water leaking in a free flow length (2) of the water feedline (1, 3) to the ion exchange container. Excess water runs over an overflow edge (7) into the washing container of the machine. Depending on a device set to the local raw water hardness, a defined part-quantity of water for regeneration can flow from the water storage container into the salt container. <IMAGE>

Patent DE-3216303-A1 (DE)
Title: Osmometer
Inventor: NOACK KLAUS
IPC: G01N13/04
Filed: 1982-04-23
Abstract: An osmometer for determining the osmotic pressure in colloidal solutions comprises a measuring cell composed of an upper and a lower cell half which enclose a sample chamber and a pressure measuring chamber separated from one another by a semipermeable membrane. According to the invention, a septum injector made of rubbery material is fitted in the inlet channel to the sample chamber and a further inlet channel connected to a pump for flushing the sample chamber also opens into the inlet channel between the septum injector and the sample chamber. The sample chamber furthermore comprises only a short channel section which is open and adjacent to the membrane. As a result, it is possible to introduce, on the one hand, sample and flushing solution into the inlet channel of the sample chamber without air inclusions occurring. Furthermore, the sample chamber can be flushed by means of the pump immediately after a measurement operation, thus making automatic operation of the osmometer possible.
