Patent DE-2413822-A1 (DE)
Title: Building-structure horizontal expansion joint covering strip - with downward drip arm on upper edge profile overlapping sealing profile
Inventor: KALDENBERG KURT
IPC: E04B1/68
Filed: 1974-03-22
Abstract: The purpose is to provide a shaped-section strip to cover expansion gaps, esp. horizontal ones, in structures, achieving perfect sealing and preventing any water penetration. The strip comprises edge shaped-sections with T-shaped insertion grooves to accommodate T-shaped junction flanges on an expanding elastic shaped-section fitted between them. The upper edge shaped-section has a drip arm pointing vertically downwards, and this partially overlaps the sealing shaped-section, which may have a cutout for its accommodation. The lower edge shaped-section may have a horizontal seating arm for a vertical drip arm on the sealing shaped-section.

Title: Trawl winch hydraulic system - uses common control equipment to keep constant rope tension and regulate depth
Inventor: DRAGSUND INGE
IPC: B66D1/50
Filed: 1974-11-26
Abstract: The system maintains a desired trawl net speed in the sea and sets this so as to regulate the net depth. The common control equipment is used to keep the trawl rope tension constant, thus setting net depth by means of speed regulation. The common control equipment (50, 23A, 23B, 40) can be made adjustable so as to keep equal tension in the ropes and regulate net depth independently of or in addition to automatic operation of both winches with the same tension, and automatic parallel control of the trawl ropes. The common control valve (40) can be adjusted so as to set the opening pressures of the pressure relief valves (23A, 23B) simultaneously.

Title: Thermostatically controlled temp. regulator, without auxiliary energy - safety device has at least two independent thermostats
Inventor: KLEE GERHARD
IPC: G05D23/12
Filed: 1974-12-02
Abstract: The thermostatically controlled regulator is particularly designed as a temperature regulator requiring no auxiliary energy. A safety device is included to bring the setting component to a safe position when certain upper and lower temperature limits are not maintained. The safety device comprises at least two, mutually independent thermostats which are also independent from the main thermostat that normally controls the setting component. The safety devices operative member can release either or both of its associated thermostats in emergency conditions. The safety arrangement can be so constructed that when the pressure of the thermostatic system falls below a certain value e.g. towards zero the safety thermostats respond and the safety device is released.

Title: Production of sleeve pattern from fleecy material - with aid for rapid precise production by unskilled person
Inventor: HUENSELER GEB JUELICHER ELISAB
IPC: A41H3/04
Filed: 1975-02-14
Abstract: Sleeve pattern is produced from fleecy material by placing a tubular shape of tin foil which is obliquely cut at one end over the arm of the person for whom the pattern is intended, pinning the lowest and highest points of the tubular shape to the lowest and highest points of the armhole of a pattern which is already pinned into a person, and pressing the edge of the shape onto the armhole and the remainder onto the arm. The tubular shape is then removed, split longitudinally at armhole level, and laid on the fleecy material to which the outlines are transferred. The tubular shape is obtained from a rectangular piece in which the corners of one long edge are folded in towards the centre, then the remaining short edges are rolled inwards and adhered to each other.

The heat tone measurement is obtd. from the temp. difference observed in the gas flow before and after the catalytic reaction.
Patent DE-2513937-A1 (DE)
Title: Determining several optically active components in a single sample - using a series of polarimetric determinations
Inventor: HAUMERSEN ALEXANDER
IPC: G01J4/04
Filed: 1975-03-26
Abstract: The concentration of several optically active substances, occurring together in a single sample, is determined by measuring the optical rotation by multiple polimetry at different wave lengths. The number of polimeter measurements should at least be equal to the number of optically active substances present in the sample and by this means the values of the concns. of the various components are determined. The measurements may be made consecutively or simultaneously. An automatic polarimeter which measures at several wavelengths is used. the angular measuring system of which is connected directly, or indirectly vian an electronic stone, to a computer. It has an automatically adjustable revolving filter. The computer is linked to a data logger and can have an optical signal also. Method is used for determining the composition of multi-component mixtures when these are optically active and of known properties. The use of polarimetry has been limited because only one component could be measured at one time. The system described allows the break down of such a mixture to give the conc. of the various components.

Title: Carburettor float chamber vent system - uses fuel pressure to change between internal and external venting
Inventor: BLOHM HANS-JOCHEN
IPC: F02M5/08
Filed: 1975-08-02
Abstract: The carburetto float chamber vent system has a vent valve with connections for internal and external venting of the chamber. This is actuated by a servo depending on an engine operating parameter. When the engine is running under load, the internal venting connection is used, and when stopped the external one. The servo (29) is operated by the fuel pressure. The vent ensures that vapours and liquids are not released to atmosphere when running, as required by some regulations. The vent prevents flooding of the engine when stopped.

Abstract: Screw press, as in DT 514470, for continuous processing of granular, agglomerate or powdered raw material, to form films, profiles etc. is improved in that (a) the mixing element is formed from individual balls, or needle rollers of the same or different dia. arranged in >=1 plane situated one behind the other; (b) the ball or rollers are supported on surface machined in the conveyor screw or its pointed tip and in the housing surrounding this. Advantageously, the dia. of the balls or roller corresponds to the inner dia. i.e. shaft dia. of the conveyor screw in the plane of the ball or roller centres. Appts. prevents the overstressing and resultant overheating and possible burning of the material e.g. p.v.c. being extracted, in extruders of the original design.

Title: Detection method for leakage current - uses total current transformer whose primary winding consists of mains phase conductors
Inventor: EBEL HERBERT ING GRAD
IPC: H02H3/33
Filed: 1975-12-09
Abstract: The transformer secondary winding is connected to an evaluation unit whose output pulses control a cut-out. The transformer has an auxiliary winding connected to a generator for a.c. magnetic bias of the transformer. Leakage current is detected by the evaluation unit as a change of the shape or keying ratio of test signal at the secondary winding (11). The evaluation unit is balanced in a leakage-free state, so that the cut-out is not affected by a tripping pulse. The time displacement of the voltage peaks is measured to enable a leak rate quantity to be evaluated.

The slot (3) in the contact spring strip (2) is narrowing in the board insertion direction, until it reaches at a point (4) the dimension corresponding to the thickness of the board (5) to be inserted. Beyond this point it is either constant or widens again. When the circuit board is inserted and lowered, contact springs (7) on one side of the slot are pressed down and make contact with contacts at the board edge. The circuit board is held in this position by a fastening device.

Patent DE-2614774-A1 (DE)
Title: Stator for eccentric screw pump vulcanised inside a thin tube - which is no thicker than needed to withstand the pumping stresses
Inventor: ZEITVOGEL JOSEF
IPC: B29C70/68
Filed: 1976-04-06
Abstract: Usually the stator has been made with a tube thick enough to serve as mould during the vulcanising; this is heavier than the pumping requires and, moreover, it needs trimming to size after the moulding. By the invention the elastomer is supported on only a thin-walled tube enclosed inside a separate support mould during the vulcanising process. The thin-walled tube is pref. made undersize in dia. and expanded during the vulcanising until it fills the support mould, which thus defines the finished size and removes the need for trimming. In expanding, the tube presses against dies that mark it with mfg. data.
