Title: Plastics, esp. thermoplastics, extruded in homogeneous stream - without prior orientation using screw relieved of axial thrusts from other components
Inventor: KOCH DIETMAR ING GRAD
IPC: B29C48/05
Filed: 1980-09-19
Abstract: Appts. and method for conveying and distributing materials, esp. plastics such as thermoplastics, uses single- or multi-screw extruders. The screw (1) is mounted within the casing (2) in such a way that no axial forces are exerted by the screw on other components; the material is distributed, without previous orientation, so that it emerges as a solid or hollow strand of material. Pref. the screw (1) is "self-centering" in the axial direction by means of a ring (3a) surrounding the screw. The expelled material s leaves through lateral openings (5) in the casing (4), to enter a surrounding duct (9) where it is recombined. The succeeding duct (10) leads to the shaping tool or mould, for example an extruder head. A flange (11) connects the casing components (2,4,8) together. A conical head (19) within the casing prevents axial force being exerted upon the screw (1). Used in the prodn.of plastics material by extruders, esp. thermoplastics. Single-screw or multi-screw extruders may be used. Friction between the screw and casing is reduced, the material is uniformly distributed as it leaves the screw zone without becoming previously oriented and the resultant partial stream overlap.

Title: Electrochemical measurement sensor for exhaust gas oxygen content - contains solid electrolyte tube with inner and outer electrodes
Inventor: LINDER ERNST DIPL ING
IPC: G01N27/406
Filed: 1980-09-20
Abstract: An electrochemical measurement sensor for determining the oxygen content of gases is esp. for combustion engine exhaust gases. Its sensor contains a solid electrolyte tube contg. an internal first reference electrode layer and an external second measurement electrode layer with a heater wire coiled round the tube. The sensor does not require a separate heater carrier, is simple to assemble, and enables the design and tooling of conventional sensors conforming to DE-OS 29 43 494 to be used. The heater wire is placed on the insulating material. The end of the electrolyte tube projecting into the measurement gas has a longitudinal slot via which the end of the heater wire protrudes into the tube longitudinal bore. The bore contains a seal preventing air from entering the sensor element measurement region.
Patent DE-3037972-A1 (DE)
Inventor: ZANZIG JUERGEN ING GRAD
IPC: H04M19/00
Filed: 1980-10-08
Abstract: In order to avoid choke coils in the feed circuit for a subscriber circuit in telephone systems, the feed voltage (UB) is connected to both lines (a, b) via the series connection of the collector-emitter path of a transistor (T1, T2) and an equivalent emitter resistor (RE1, RE2). To achieve substantial symmetry with normal-tolerance transistors, the transistor collectors are cross-connected with the bases via resistors (RB1, RB2). Furthermore, the transistor bases are connected via a Zener diode (Z1) to one another and via resistors (RZ1, RZ2) to the terminals (A, B) of the feed voltage. A feed circuit is produced which is highly symmetrical, has low insertion loss and feed current limitation. <IMAGE>

IPC: G01B21/02
Filed: 1981-02-28
Abstract: In a drive device for a sleeve (3), guided in the Z direction, of a co-ordinate measuring machine, the sleeve (3) being mounted on a drivable steel belt (8), the aim is for the belt (8) to exert on the sleeve (3) practically no forces acting transverse to the middle longitudinal axis (Z, 3').

Patent DE-3110663-A1 (DE)
Title: Automatic machine for the winding of strand-like material, especially cable
Inventor: MUELLER HANS-JUERGEN
IPC: B65H67/04
Filed: 1981-03-19
Abstract: The invention relates to an automatic machine for the winding of strand-like material, especially cable, onto drums, with a feed station for empty drums, with a winding station receiving the fed empty drums, and with a depositing station depositing filled drums on a transport track or the like, the winding station having a guide member which is preferably designed as a tube projecting with a free end towards a drum and through which the cable to be wound onto the drum runs, and having a cable-cutting device. On each empty drum fed, the cable end projecting from the guide member has to be threaded into a core hole of the drum. In previous winding appliances, the threading-in has taken place manually, with the result that the winding operation cannot proceed in a completely automatic way. According to the invention, the guide member is equipped with a sensor which senses a drum core hole receiving the start of the cable and which controls the rotary drive of the drum in such a way that, when the drum is braked completely to a standstill, the guide member is in a position coinciding with the core hole, so that, when the cable strand is advanced automatically through the guide member, the start of the cable is pushed forwards into the core hole. The operation of winding cables onto drums can thus be carried out automatically.

Title: Circuit arrangement for evaluating AC signals formed from a plurality of simultaneously transmitted alternating currents with different signal frequencies, in telecommunications systems
Inventor: GRUENER PETER ING GRAD
IPC: H04Q1/457
Filed: 1981-04-15
Abstract: The invention relates to a circuit arrangement for evaluating AC signals formed from a plurality of simultaneously transmitted alternating currents with different signal frequencies, in particular for evaluating multi-frequency code dialling signals according to CCITT Recommendation Q.23, in telecommunications systems. The frequencies are identified by counting the clock cycles with a high clock frequency compared with the signal frequency which occur during a measurement cycle, a measurement cycle comprising one or more signal frequency cycles. The clock frequency is selected in such a way that only the higher-value counter outputs need to be evaluated. Substantial immunity to interference is achieved by comparing two consecutive counter results in each case.

Abstract: A novel additive and a novel process for producing crude oil from underground deposits by means of surfactant/water flooding is provided. The fluid used contains water and a silicon dioxide-dialkylsiloxane which, as additive, reduces the stability of the interface film of the surfactant molecules, which are dissolved with their hydrophobic part in the oil phase and with their hydrophilic part in the aqueous phase, and thus increases the effectiveness of the surfactant fluid used for producing the crude oil.

Patent DE-3138809-A1 (DE)
Title: Energy store
Inventor: BARETH RUDOLF
IPC: F03B13/00
Filed: 1981-09-30
Abstract: The invention relates to an energy store, in which the energy of the water, which flows from a storage reservoir at a higher altitude to the turbine, is first stored. When water flows from a height of 10 m into the 100 m long energy store, the air in the hoses is forced under 1 kp pressure against the pipe wall. With energy stored, the energy store has a diameter of 2 m, resulting in a pressure storage area of 6,280,000 cm<2>. On storing, 314,000 litres of water (314,000 kp of energy) flow out of the storage reservoir and these press in the energy store against a storage area of 6,280,000 cm<2> under 1 kp. This gives a storage energy of 6,280,000 kp. By opening the energy store towards the turbine (Figure 4), the stored energy is released. The water displaced by the expanding air rushes with an energy of 6,280,000 kp to the turbine. The energy store increases the energy by a factor of 20. <IMAGE>

Title: Method for the transmission of commands and messages with signalling dependability or non-dependability
Inventor: STEGER ERNST DIPL ING

Filed: 1981-10-23
Abstract: The invention relates to a method for the transmission, with signalling dependability or non-dependability, and redundant processing of commands or messages by means of a switch-over and monitoring device. It consists in that data having the same information content are supplied to redundant data processing channels and are separately processed, that a monitoring device establishes whether all redundant data processing channels are operating, that when a data processing channel fails, the switch-over device switches from a series circuit outputting commands or messages with signalling dependability to a parallel circuit outputting commands or messages with signalling non-dependability and that a corresponding message is output. <IMAGE>
