Title: Voltage stabiliser battery-powered measuring appts. - uses relay controlled by threshold detector and bistable amplifiers
Inventor: ROPPELT GUENTER ING GRAD
IPC: H02H3/24
Filed: 1977-07-14
Abstract: A protection circuit for battery powered measurement devices uses threshold circuits to detect undesirable operating conditions. When an invalid condition occurs a bistable amplifier switches over and causes a relay to interrupt the input circuit. The circuit operates for power failure or when the voltage is too low for normal operation and uses minimal current so as not to preclude long battery life. The threshold switch is a zone diode and series resistor in parallel with the protection circuit auxiliary supply. The protection circuit uses two bistable amplifiers each contg. complementary transistors and each connected to one side of the relay coil.

Title: Therapeutic muscle contraction registering machine - has pen directly operated by keyboard to form curve on chart
Inventor: RODLER HANS
IPC: A61N1/08
Filed: 1977-12-05
Abstract: The electrical therapy and diagnostic machine which derives a curve corresponding to muscle contraction etc. has the operating keys arranged near the curve registering sheet so that they correspond with the coordinates of the curve registering chart. The measured value outputs are directly applied to the chart. The keys vary the pulse width in a logarithmic stepped manner, each key indicating its ordinate. In parallel with the ordinate is a slide register which calibrates the intensity of the current. Each key is connected to an adjustable device which varies the force of the current operating the writing point as it moves over the paper. When the key is released, a strip is moved against the pen to form a point on the chart. A heat sensitive paper may be used, and the tip of the pen may be heated to form the points on the curve.
Patent DE-2756621-A1 (DE)
Title: Two-ply roofing felt with polyester nonwoven base and EPDM rubber top - the elongation of the substrate being longitudinally and transversely dissimilar to accommodate excessive temp. variations
Inventor: ALBERS GUENTER
IPC: E04D5/10
Filed: 1977-12-19
Abstract: Roofing felt comprises a laminate whose base ply is a polyester fibre fleece and whose top ply is a EPDM elastomer. The fleece is elastic and compressible across its width, its longitudinal elongation being less than its transverse elongation. This serves to compensate for the difference in the coeffts. of thermal expansion between top and base plies, thus ensuring that the roofing felt will lie flat even under extreme temp. conditions. The fleece may be perforated. The top ply is suitably fitted with an additional polyester fleece edging for facilitating overlap bonding of adjacent webs. The overlap is sealable by means of a weather-resistant pasty sealant.

Title: Permanently curved thermoplastic film - produced by passing through rollers system with specific temp. difference between its side
Inventor: ANDERSEN HEINZ-ERHARD DIPL ING
IPC: B29C53/04
Filed: 1977-12-23
Abstract: A permanent curvature is produced in thermoplastic film by passing it over a first guide roller, round a small dia. roller through >180 degrees, and over a second guide roller which is sepd. from the first by slightly more than double the film thickness. The small dia. roller lies between the other rollers and is sepd. from them by the thickness of the film. The film is heated whilst passing round the small roller with a difference of >10 degrees C between its side on the roller and its other hotter side, the former temp. being 15-70 degrees C and the latter 50 - 170 degrees C; the film is rapidly cooled to 30 degrees C on passing round the second guide roller.

Title: Soluble tungstate salt prepn. - by calcining iron, manganese and/or alkaline earth metal tungstate(s) with donor cpd., and leaching with soln. contg. e.g. ammonium ions
Inventor: KASSERRA HANS PETER
IPC: C01G41/00
Filed: 1977-12-30
Abstract: A tri(alkaline earth metal) tungstate is made from a tungstene compsn. chosen from alkaline earth metal tungstate iron tungstate and/or manganese tungstate by calcining the tungstate compsn. with an alkaline earth metal donor cpd. at 800-1400 degrees C. The donor cpd. is used in excess of the stoichiometric amt. needed to form the trialkaline earth metal) tungstate. The obtd. tri(alkaline earth metal) tungstate is treated with an aq. soln. contg. cations from NH4+, Na+, and/or K+ and anions from CO32-, HCO3-, OH- and /or PO43- at 20-40 degrees C. This form a tungstate salt which is soluble in soln. on reaction with the cations while reaction of the anions with the alkaline earth metal forms an insoluble cpd. which can then be sepd. from the soln. Tungstate values can be extracted with high yield whilst decreasing contamination by impurities. The process uses relatively inexpensives materials for the mfr. of W (cpds.) at economical rates and levels of W recovery. The process is pollution free.

Title: Lubricating wiper head on double-acting twister - has abrasion proof disc assembly brushed by thread each revolution
Inventor: JENTER ERICH
IPC: D01H7/88
Filed: 1978-01-27
Abstract: A yarn treatment agent is applied to the thread running over the support dish on the spindle of a double-acting twisting machine, by means of an absorbant wiper head. This projects from below, into an annular recess of the dish, intersecting the line of motion of the thread. The wiper head is arranged in a housing in which it is soaked in the fluid held in a container, and consists of a number of very thin metal plates or rings. Their lower end is in contact with a wick impregnated with the agent, or it may be immersed in a fluid. The capillary action of the gaps between the discs, lifts the fluid to the upper zone of the head, which is brushed by the thread. The wiper thread is of simple design, and whilst it treats the thread gently, so that no damage is done, it is practically unaffected by abrasive forces.

Title: Centrally-controlled telephone exchange - locates de-centralised faults and sends alarm signals to replacement and central control units
Inventor: HERZING HANS DIPL ING
IPC: H04Q3/545
Filed: 1978-05-12

Title: Incandescent lamp holder with integral switch - disconnects supply when lamp is removed to give safe switching action
Inventor: HULTBERG TORE
IPC: H01R33/96
Filed: 1979-01-26
Abstract: The lamp holder has a fixed base platform (16) with stationary switch contacts (20) connected to the incoming leads (22). A moving contact assembly (8) fits into the recess formed by a rim (17) on the platform (16). The moving assembly comprises a plate on one side of which are the contacts (32; 30, 40) for the lamp. On the other side are the moving contacts (34, 36) of the switch. The pins (34, 36) which are the moving contacts slide in slots (18) in the platform. When a lamp (14) is screwed in, torque is transmitted via the lamp contacts (40) which turns the plate to bring the moving contacts (34, 36) against the fixed (20) ones. A coil spring (26) can be fitted to separate the contacts when the lamp is removed. The construction gives a safe switching action. As the action is rotary, instead of axial, inadvertent closure of the contacts with the lamp removed is inhibited.
