Title: Coated tape mfr. - by extrusion through die on revolving disc carrying tape
Inventor: KLEUSER WINFRIED
IPC: B29C48/12
Filed: 1977-12-24
Abstract: Strips or beadings for use as semifinished product for edge protectors are produced from a continuous carrier strip of plastics or textile to which a plasticised layer has been applied. This layer is plasticised and continuously applied by an extruder to the moving carrier strip at a tangent. The system produces endless strips at low cost, using simple machinery.

Title: Bonding spring strand to continuous cable - forming circular shape which will not open up spontaneously
Inventor: SCHEFFLER GUENTER DIPL ING
IPC: B21F35/02
Filed: 1978-02-09
Abstract: Spring strand is bonded to a continuous cable by taking the ends and twisting them against each other so far that the section between the ends forms figures of eight. The two ends are brought together and twisted within each other until the figures of eight have combined. By additionally twisting the ends, they cannot unwind again. The continuous strand, so formed, is placed in a groove and given side support. Process forms the spring strand into a circle which will retain its shape and not open up spontaneously.

Title: Three=phase traction motor control system - has two running speeds and regenerative braking is achieved between high and low speeds
Inventor: HUEBEL EGON
IPC: B60L7/18
Filed: 1978-06-13
Abstract: The three phase traction system with a single motor (M) is designed to run at two set speeds, one high speed for normal travel and a much lower speed. When the vehicle is to be braked from the cruising speed the control is set for the lower speed so that a regenerative braking is obtained, after which the normal friction brakes are applied. The regenerative braking is controlled by a simple comparator circuit to reach a set lower speed, after which the friction brakes are progressively brought into action, and the drive is discontinued. The system allows a three phase traction vehicle to be stopped in a controlled distance, especially for remote control.

Inventor: STIEFEL MAX ING GRAD
IPC: B01J47/14
Filed: 1978-08-01
Abstract: A method of monitoring ion exchangers in a nuclear power plant for determining the boron content of the liq. purified by the exchangers is claimed. A measuring vessel is supplied, through separate feed lines, with the purified liq. from the ion exchanger, with mannitol soln. and with soda liquor; the total of these three liquids is =1 litre and the contents of the measuring vessel are mixed, the pH value is measured and the soln. is then discharged to the effluent collecting system. Used partic. for monitoring the performance of ion exchangers used for treating prim. cooling water of a reactor plant towards the end of the fuel cycle in order to change the boron content. The method requires a much smaller quantity of mixt. to be prepd. than with a previous method. The new method gives rise to a much smaller quantity of active effluent but nevertheless provides a reliable and rapid statement about the condition of the ion exchanger.

Title: Force locking bolt joining two components - has adjustable fish-plate engaging hole wider in two sliding directions
Inventor: FRICKER SIEGFRIED
IPC: E04B1/26
Filed: 1978-11-30
Abstract: Relative sliding movements, in two directions are permitted by the device connecting two building components together. It exerts a force-locking effect in the third dimension, and it is adjustable. A threaded bolt (12) is anchored in one component (10), in the direction of connection. This has a fish plate (13) adjustably set on it, vertically to this direction, engaging an aperture (14) in the other component (11). The aperture extension in the connecting direction equals the thickness of the fishplate, while in the two other directions it exceeds corresponding dimensions of the plate. This prevents bending in the direction of the components sliding movements.
Patent DE-2853818-A1 (DE)
Inventor: GRAF RUDOLF
IPC: H01H33/70
Filed: 1978-12-13
Abstract: The switching path, which is produced between a stationary contact piece (17) and the moving contact piece (16) during the switching-off stroke, is surrounded by a blasting channel, for example a blasting nozzle (23), to which extinguishing gas is fed under pressure. In addition, a sound generator (24; 24', 24'', 29) is provided in the region of this switching path, which sound generator is focused onto the axis (25) of the blasting channel and, during the switching-off stroke, produces radially inwardly directed sound waves in order to produce turbulence via the extinguishing gas flow at the arc (18) which forms in the region of the switch axis (25). A turbulent flow produces better cooling of the arc (18) in the vicinity of the current zero crossing. On the other hand, the sound waves produce virtually no loss of kinetic energy in the extinguishing gas flow, so that said flow can strike the arc in the longitudinal direction in the high-current region, and can cool it. <IMAGE>

Title: One-shot direct voltage converter load current evaluation - using measurement transformer and capacitor connected in parallel with load to derive secondary winding signal
Inventor: FREYE KLAUS-DIETER
IPC: H01F38/24
Filed: 1979-05-30
Abstract: A circuit for evaluation of the load current of a one-shot direct voltage converter has a measurement transducer in the output circuit.

The measurement transducer is a ring core transformer. For separately controlled one-shot blocking converters a measurement signal derived from the measurement transformer secondary winding (w2) is fed to the input of a control generator (ST) for the electronic switch. For flow transducer applications a further ring core transformer is used with opposite secondary current and its primary winding in the current circuit of a flow transducer electronic switch.

Title: Angular reflector for vehicle headlight - has steps at sides to provide seats for stacking during fabrication
Inventor: DAUMUELLER HANS
IPC: F21V7/00
Filed: 1979-08-11
Abstract: The headlight reflector (10) is made of plastic and has a stepped paraboloid (16) in both parallel side sections (12) on each side of the optical axis (13). The stepped part has no optical effect and is used solely as a resting surface allowing several reflectors to be stacked one inside the other during fabrication, thereby saving space. Since the surfaces that come into contact in the stack are not used to reflect light any damage done to them does not result in a reduction in the reflectance value of the surface.

Title: Dry vulcanisation of wires or cables by radiant heat - in tubes with internal resistance heating strips on surface
Inventor: FOCHT HARRY
IPC: B29C48/06
Filed: 1979-09-28
Abstract: A vulcanising and cross-linking apparatus for elongated rubber and/or plastics products such as cable coatings and the like uses radiant heat inside a long vulvanisation tube containing inert gas and elongated resistance heating elements. The resistance heating elements are long strips laid parallel to the axis of the vulcanisation tube on its internal face or on a coating of that face. The resistance elements (12) are of chromium, bronze, brass, copper or alloys of these. Used for the dry vulcanisation under inert gas of long products such as cables, etc. By dividing the vulcanisation section into a series of flanged tubes, each insulated from the others, each section can be independently supplied, e.g. from the secondary side of a transformer; this enables the entire thermal control of the process to be very easily carried out.
