Title: High capacity telecommunications cable - preventing diffusion of sealing cpd. into conductor sheaths
Inventor: DAGEFOERDE HANS-GERD DIPL ING
IPC: H01B11/00
Filed: 1974-06-13
Abstract: High capacity telecommunications cable comprises individual conductors insulated by cellular polyethylene sheaths and surrounded by an oil-derived sealing cpd. Each conductor is coated on its sheath with a high-elasticity, diffusion-inhibiting, light-curable reaction resin, pref. urethane, polymer, by passing it continuously through a dark drying zone and encasing it in a thin film of the resin, then curing the film in a subsequent light zone. This prevents deterioration of the insulation of the individual conductors by the sealing cpd. so that the low dielectric constant of the sheaths and their low phase angle will not vary.

Title: Electronic measurement circuit - designed esp. for electricity meter with variables derived from mains voltage and load current
Inventor: TSCHUMPEL HARTMUT DIPL ING
IPC: G01R21/133
Filed: 1974-09-20
Abstract: Mains voltage and load current variables are applied to a multiplier whose output is applied through an invertor and/or a switch to an integrator for the mean value formation.

Title: Direct current drive for motor vehicles - has thyristor in resistance circuit that balances out power generated during braking
Inventor: BAUM WALTER DIPL PHYS
IPC: H02P3/08
Filed: 1975-01-07
Abstract: The drive has a resistance to balance out the power generated by the braking force on the armature. It has the advantage of a compact design unsing components of high reliability. The resistance has a thyristor which is switched into the required. The switching of the thyristor is achieved by measuring the potential in the armature. When the braking is achieved by change of field direction, and the resistance, armature and field are all in series, there is a freely acting diode short circuiting between field and armature and the thyristor is in parallel to the resistance. When the resistance is in parallel with the armature, it is also in series with the thyristor. There is a protective resistance for the igniting electrode of the thyristor. An extension to the design has a further thyristor and a logic circuit incorporated.

Title: High moisture solid fuel drying - by heating aq. coal paste at high pressure, decanting and charging directly to gasifier
Inventor: HUETTNER RUDOLF DIPL CHEM DR
IPC: C10J3/46
Filed: 1975-05-13
Abstract: Solid fuel with a high content of fixed moisture is dried, after a size reduction to under 10 mm, at pressures of 15-110 bar and a 200-300 degrees C with the addition of water and/or steam to produce a paste. This continues until the fuel has lost its colloidal structure and the water, originally fixed and later liquid, has been eliminated. The dry fuel is then fed into the gasifier reactor which is operated at a pressure below the drying pressure. This avoids the environmental pollution caused by a pressure-less drying by steam in tube furnaces or with hot gases in fluidized bed dryers. The costs for oil in systems using a coal/oil paste are saved; the heat input required for the evaporation of water is kept to a minimum.

Title: Electroplating connecting wires of electronic components - using iron-centred connectors attaching the components magnetically to a holding frame
Inventor: EILERS WALTER
IPC: C25D17/06
Filed: 1975-08-19
Abstract: Equipment for handling large numbers of small electronic components such as resistors or diodes locates these in correct position using the magnetic attraction between holders contg. fixed permanent magnets and the connecting wires for the components which are copper-covered iron. Used in electroplating units which handle large numbers of components with copper-covered iron connecting wires and which are intended to plate these connecting wires with metals such as nickel or tin to make their subsequent soldering an easy matter. As compared with plating large numbers of components in revolving drums, this method greatly lessens the possibility if damage by bending of the fragile connectors, and it is cheaper in capital and operating costs than the alternative magazine handling appts.
