Inventor: PLENTZ RUDOLF
IPC: F16D65/18
Filed: 1976-05-18
Abstract: The brake cylinder is esp. for disc brakes of vehicles. An elastic member (1) is positioned between the brake piston (3) and the brake fluid (5). A hollow space (9) free of brake fluid is formed between the two parts and th elastic body is pressed into the hollow when the pressure in the brake fluid increases.

Title: Control circuit for transistor switch - has control pulse passing via parallel RC circuit to base of switching transistor
Inventor: KINDLER HARALD ING GRAD
IPC: H02M3/335
Filed: 1976-07-07
Abstract: The control circuit, for a transistor switch, passes its control pulse to the transistor switches (1) base via a parallel RC circuit (17, 18) and a zener diode (19). The resistor (18) is chosen large enough so that part of the control current flowing over it is insufficient to drive the transistor switch into saturation if tolerances are exceeded. If a Darlington pair is used as the switch a resistor (3) and a diode (4) may be connected in parallel between the input transistors base and its emitter (also the output transistors base). The output transistors base/emitter junction is shunted by only one resistor (2).

Title: Overload protection system for power transistor - operates using base to emitter voltage of transistor as measure of junction temperature
Inventor: KETTERLING HANS-PETER DIPL ING
IPC: H03K17/082
Filed: 1976-12-14
Abstract: The power transistor (4) has a low resistance (5) in series with its output and a potential divider (6, 7) across the resistance and transistor base connection. Tappings (13, 10) are taken from the emitter of the resistor and the divider common point and applied to a comparator (11). A reference voltage is included in one tapping. The tappings, resistance, transistor base and divider form a bridge circuit. At normal temps. balance conditions apply to the bridge and there is no output from the comparator. If the junction temp. becomes too high the base-emitter resistance falls and unbalances the bridge giving an output from the comparator which is used to turn off the transistor. Typically the comparator controls a multivibrator (15) which, after acting to turn off the power transistor, switches it on again after an interval. If the junction temp. has normalised then it stays on, if not the switch off cycle is repeated.
Patent DE-2657949-A1 (DE)
Title: Temp.-compensated thin film circuit mfr. - by sputtering aluminium-tantalum resistors and capacitors and nickel-iron contacts and counter electrodes
Inventor: KAUSCHE HELMOLD DIPL PHYS
IPC: H01L21/70
Filed: 1976-12-21
Abstract: Prodn. of thin film circuits with temp. -compensated RC-members from an AlTa alloy layer with ca. 3-17 atom-% Ta in Al, contg. N2 or pref. O2 or CO2, involves sputtering onto a nonconductive substrate in a reactive gas mixt. contg. O2, CO2 and/or N2 and adjusting the TCR value by the Ta content and the partial pressure of the gas and the TCC value of the capacitors by tempering so that it is (practically) the opposite of the TCR value, as in DT 2546675. The sputtered NiFe layers are used as contacts for the resistors and counter electrodes of the capacitors. These NiFe layers pref. are sputtered simultaneously, esp. by cathodic sputtering with a ring discharge plasma. Increased junction resistance is avoided (edge resistance ca. 1 ohm.mm), whilst the dielectric of the capacitors is not damaged. Since the resistor layers can be tempered before contacting, sputtered Ni or Cu films can be used as conductor tracks, counter-electrodes and contact layers, instead of the dearer vapour-deposited or Au layers. The yield of resistors and capacitors with an insulation current of 2 A/F is >90%.

Title: Domestic water saving system with collector tank - utilises waste water from appliances and baths for toilet flushing
Inventor: KLAWE HEIKE
IPC: E03C1/122
Filed: 1977-06-11
Abstract: The arrangement for saving drinking water is used preferably as a domestic arrangement. Waste water from baths, washing machines and dishwashers is fully utilised. This reduces the load on the waste water system and in sewage works as well as in water purification plants. In a house, waste water is pumped or fed into a tank in a cellar. This water is returned into the system for flushing toilets. The water from baths, hand basins and domestic appliances is collected by a common dow pipe and passed through a replaceable filter and collected into a tank. This tank has an overflow connected to the public waste water mains.

Title: Mixed acid orthophosphate ester prodn. - from phosphorus pent-oxide and excess of alkanol and poly-ol, useful e.g. in cleaning compsns.
Inventor: KLOSE WERNER DIPL CHEM DR
IPC: C07F9/09
Filed: 1977-09-05
Abstract: The parent patent describes prepn. of a mixt. of acid orthophosphate esters by reacting P2O5 with a mixt of a monovalent alcohol (I) and a 2-12C alkanepolyol (II) with 2-6 OH while keeping a P2O5:(I):(II) mole ratio 1:2:4/n (n = no. of OH gps. in (II)). The reactant are mixed or kneaded at 0-120 degrees C with exclusion of moisture and under an inert gas for 1-6 hrs., then the mixt. cooled. In this addn. (I) and/or (II) is used in molar excess relative to P2O5. The mixts. are useful as components of acid cleaning compsns. because of their relatively low corrosivity. They can also be used, opt. after neutralising, as emulsifiers, wetting agents, lubricants, foam-suppressants, antistatics, and (if they contain halogen) as intermediates for flame-proofing agents. By using an excess of alcohol the viscosity of the mixt. is reduced to side reactions leading tocoloured impurities are suppressed.

Title: Identification system for objects with markers - uses components with different threshold magnetic field strengths and localised permeability
Inventor: BECKER KARL
IPC: B07C3/12
Filed: 1977-12-09
Abstract: A system of identifying objects provided with marker bodies uses electromagnetic transmitters and non-linearities of the magnetisation curves as evaluated by a receiver. The system enables unequivocal recognition of the marker bodies. The identification criterion employed is the initial region of marker body permeability. A threshold field strength (H3) is used in which the differential permeability has an essentially constant value. Marker bodies with different threshold field strengths are used for identification of different objects. The system is suitable for personal identity cards, bank cards etc.

Title: Wall cladding panels in grid pattern - are laid by pressing them between stems of insulating carpet initially cemented to wall
Inventor: PRAEKELT WERNER
IPC: E04F13/14
Filed: 1978-07-03
Abstract: Fixing elements made of resilient material are fixed to the wall at an interval from panel corners, and wall panels are locked in position between them as in the main patent. Here a carpet, bearing a grid pattern of grid stem pieces for snapping panels in position, and made of insulating lengths of material, is cemented onto the wall being covered.

Title: Cable connection for press pilot valve - has insulating layer and washer between screw connection and valve chamber below
Inventor: HIRN HELMUT
IPC: F16K31/40
Filed: 1978-09-22
Abstract: The top plate for a hydraulic or pneumatic press has an insulation system for a connection cable for a valve block with a control valve. The cable is secured by a screw which fits into a tapped hole in a cylindrical piston above the valve block. The top surface and upper part of this piston carry an insulating layer and a sealing ring is fitted around the top. This insulates the valve chamber below from the contact screw connection zone, where the screw also passes through an insulating bush which receives the pressure when the screw is inserted. The bottom of the piston is shouldered down to a smaller diameter, forming a space communicating with a control channel to pilot valve above.

Title: Blind or roller shutter belt winding mechanism - effects clamping between swivelling return lever and clamp lever with stop
IPC: E06B9/78
Filed: 1978-09-23
Abstract: A spring socket, belt-clamping lever swivelling about an axis, and clamping stop below the end of the lever facing the socket, are incorporated in the winding mechanism for the belt operating roller shutters or venetian blinds, the belt being led between stop and lever. The lever (12) is fitted with a fixed limiting stop (22) and a swivelling return lever (23). The belt (16) is clampable between these two levers, in face of the action of the spring in the spring socket. It may be held between a protrusion on the return lever and the clamping lever, while the limiting stop is a bolt above the end of the clamping lever facing the socket. Without wear on the belt, this automatically prevents max. belt tension from being transferred to lowered blinds, with resultant admission of light.
