Inventor: BIEBRICHER FRIEDHELM
IPC: F16K1/22
Filed: 1974-06-14
Abstract: The actuator cylinder (10) is mounted on one side of the valve body with its axis at right angles to the axis of the valve spindle. the cylinder (10) houses two pistons (15) joined by the connecting rod (16) which carries a bolt (29) which pivots in a transverse hole. The bolt head is provided with a slot which forms a guide for a pin (28) which is rigidly fixed by a screw (30) to the hollow shaft (22) which is mounted on the valve spindle with a key which fits the keyway (23).

Title: Rail wheel system for track bound vehicles - has wheel and rail with corresponding angles instead of flange
Inventor: MAIER EMIL
IPC: B60B17/00
Filed: 1974-06-22
Abstract: The outer flank of the wheel (2) is trapeze shaped (6) to correspond with the side contact surface (4) of the rail (1). The rail (1) has a horizontal running surface (3) leading to the outer flank (4) incline which acts as a safety surface so that the wheels and the rail are continually in contact with each other. The patent claims that derailment is impossible. The vertical load of the rail vehicle is supported by the horizontal mating surfaces (5, 3) of the wheel and rail, which is always greater than the component acting on the inclined surface.

Title: Oil retaining ring for winches - has flexible support section pressure plate annnd spring reinforced rubber clamp
Inventor: HOMOLA GERD
IPC: F16J15/3224
Filed: 1974-06-28

Title: Polyurethane tube is cooled and flattened without sticking - by using internal ribbed structure to prevent area contact
Inventor: MOSES RICHARD
IPC: B29C48/13
Filed: 1974-07-05
Abstract: A method of making thin thermoplastics (pref. polyurethane elastomer) tubing, e.g. by extrusion, where the tube is subsequently flattened, cooled and wound onto a reel, is carried out by initially forming the tube so that it has internal longitudinal ribs which, when the tube is flattened, produce lines of internal contact between the opposite sides of the tube, with out-of contact bands between them. The longitudinal ribs and the bands between them amy be of a helical or oscillating pattern. Method is esp. suitable for making the internal tubular lining for fire hoses. At the same time, high production rates are possible, without risk of the opposite sides of the tube sticking together. Powder or oily type parting agents are not reqd.
Patent DE-2434006-A1 (DE)
Title: Thermostat for heating system - has varistor in parallel with PTC resistor and ignition capacitor
Inventor: KLEINSCHMIDT PETER DIPL PHYS
IPC: G05D23/24
Filed: 1974-07-15
Abstract: The thermostat comprises a thyristor which closes or breaks the heating circuit, a PTC resistro and an ignition capacitor. The thyristor (2) gate is connected through a triggering diode (6) to the junction point between the PTC resistor (4) and ignition capacitor. The varistor (7) is a ZnO varistor. The latter has, for example, a threshold voltage of 60 i.e. below this value it has a very high resistance but above this value a very low resistance. As soon as the a.c. at the terminals (20, 21) exceeds 60 V the varistor (7) short circuits the PTC resistor (4) and ignition capacitor. The high capacitance of the varistor quickly restores the charging loss of the ignition capacitor.

Title: Miniature DC motor - speed is adjustable and remains constant irrespective of load
Inventor: SANDER HORST
IPC: H02P7/29
Filed: 1974-11-22
Abstract: The miniature d.c. motor comprises means to continuously supply an electric signal proportional to the motor's actual speed. A pulse shaper continuously converts this signal into rectangular pulses and a pulse generator delivers a pulse train with constant pulse repetition frequency corresponding to the motor's nominal speed. Pulse generator and pulse shaper outputs are connected to a phase comparator which delivers control rectangular pulses corresponding to the phase shift between two pulse trains. They control a power stage. The pulse generating stage is essentially a bistable scanning circuit or Schmitt trigger regulated from the output voltage of the a.c. tacho generator.

Title: Leather prodn. from pelts contg. water - pickled, tanned and dubbed in organic water immiscible non-polar solvents
Inventor: GRAF HANS-DIETER ING GRAD
IPC: C14C3/00
Filed: 1975-07-19
Abstract: Leather is produced by pickling, tanning, neturalising, after-tanning and dubbing in non-polar, water-immiscible organic solvents, e.g. chlorohydrocarbons and fluorochlorohydrocarbons. The unhaired pelts contain 50-80 wt.% water. Appearance and hand of leather is equal to that of leather tanned by standard processes. formation of polluting waste waters is avoided. Consumption of chemicals is reduced. Low water content of leather shortens drying time. Power consumption is saved. Pickling, tanning and other chemicals may be added directly or preliminarily dissolved or dispersed in organic solvents, but not in aq. solns. Specifically, the unhaired pelts are treated with aq. solns., by standard process, up to and including pickling, followed by centrifuging, squeezing or draining before tanning, neutralising, after-tanning and boiling.

Filed: 1975-08-01
Abstract: The saw-tooth surface of the lens consists of optical and non-optical surfaces which alternate in the form of concentric circles, whereby the non-optical surfaces are rough. In the case of a lens assembly for an overhead projector two Fresnel lenses have their saw-tooth surfaces attached to each other. The rough surfaces can be produced, e.g. on plastics lenses made in a metal mould, by rolling the plastics material against non-optical surfaces of the mould, which may be previously sand-blasted.

Title: Separator to remove inflammable liquids from water - having vessel with conical top and vertical dip pipe for water overflow
Inventor: MEIER GEB KOSS ALWINE
IPC: B01D17/02
Filed: 1975-08-16
Abstract: Device for continuous separation of liquids of differring specific gravities and/or viscosities consists of a vessel in with a conical gas tight cover rising to a point. At this point is an overflow pipe. also through the cover enters the inlet line on one side and on the other the outlet line with approx. twice the cross sectional area of the inlet tube. This has an L shaped outlet branch outside the vessel with a lower level than that of the inlet branch. On the upper edge of the vessel is a top section of the same geometrical form whose inner wall and cover has a frost protecting layer. The run off tube has an open top for venting and deaeration. The base is inclined at an angle to the walls, the deepest point being below the inlet. Esp. for separating oil, petrol or other light inflammable liqs. from water. Common separators use float operated valves to control the liquid interface. Waxy encrustations can appear on the valve seat and sometimes light inflammable liquids escape. This a fire and explosion hazard. Additionally if there is a vapour spare above the light liq. this a containing explosion hazard. The device claimed avoids these problems and also gives frost protection.

Title: Automatic colour film colour correction - uses grey wedges recorded in film sound track for TV reproduction
Inventor: APPELDORN WERNER VAN
IPC: H04N9/11
Filed: 1975-12-09
Abstract: A colour correction system for colour film shown on TV employs an optical system built into the camera. To derive a colour correction criterion from the light at the scene. This optical system generates a sharply focussed, rectangular beam of light whose intensity is kept constant. A grey filter (19) is inserted into this beam at the colour camera stepping frequency. A series of grey wedges synchronous with the colour picture series is recorded. During picture reproduction, light pulses scanned from these wedges are converted by narrow band filters (R,G,B) for primary colours red, green, and blue and by a photocell into consecutive and recurring chronimance signals red, green and blue. They are used for automatic colour control of the t.v. colour film pick-up.
