Title: Terminal clamp for insulated wires - has centre arm sliding into hollow part formed by two outer clamping arms
Inventor: BERKMUELLER CHRISTOPH
IPC: H01R4/24
Filed: 1975-07-15

Title: Microfilm camera modifiable as microfilm projector - realised by making film locating plate interchangeable with condenser lens
Inventor: SCHAUT JOSEF
IPC: G03B27/58
Filed: 1975-08-30
Abstract: When the instrument is used as a camera, a locating plate holds down the film or slide coming from the cassette while the photographic exposure is made through the.

Title: Isocyanurate modified polyesterimide insulating lacquer - contg. glycol ethers or diacetone alcohol as solvent
Inventor: OHM KLAUS DIPL CHEM DR
IPC: C09D5/25
Filed: 1975-09-19
Abstract: Electro-insulating lacquer for the prodn. of heat resistant coatings for metal wires is based on polyesterimide, dissolved in solvents. The resins are modified by condensation (by cooling) of tris-(2-hydroxyethyl)-isocyanurate or tris-(2-carboxyethyl)-isocyanurate and have an OH no. 150-600. The solvent is based on (di)ethyleneglycol monoalkyl ethers and their esters and/or diacetone alcohol. Use of objectionable solvents (e.g. DMF, diacetamide, phenols etc.) to dissolve the resin is avoided. Solns. based on solvents of the invention also have lower viscosity than obtd. with other solvents so that more resin can be dissolved. They also have improved storage stability.

Title: Power generator with piston cylinder unit - has compressed air line with regulator valve and pressure release aperture in cylinder wall
Inventor: ZADA WAGUIH
IPC: G01M17/04
Filed: 1975-11-08
Abstract: The power generator has a pneumatic piston-cylinder unit with a compressed air line opening into the cylinder between the piston and cylinder ends. At the start of the working stroke, the piston is brought into a definite start position and is displaced axially under the action of compressed air in the cylinder. The compressed air line (4) is connected directly to a compressed air supply which is switched on by operation of the power generator without the intermediate connection of a cut-off valve. A regulation valve (5) is arranged within the compressed air line (4) to regulate the compressed air flow. In the end region of the cylinder (2) away from the air line, there is an opening (6) in the cylinder wall (2, 3). This is cleared by the piston (3) after a stroke (a) which is longer than the required working stroke, so that the compressed air is the cylinder can escape.

Title: Fabric edge finishing - having a band carrier for the fabric to allow seaming round narrow radius curves without fabric distortion
Inventor: AHNERT PETER
IPC: D05B33/02
Filed: 1976-06-12
Abstract: In seaming or finishing fabric sections, with a sewing machine, the fabric workpiece is manipulated and moved through the sewing station according to the fabric contours. A band carrier moves parallel to the sewing machine carrier at a gap of 5-50mm from the sewing machine carrier, moving at a speed of 3-15% slower than the sewing machine carrier. The band carrier starts to move on the fabric workpiece near the sewing machine foot, at right angles to the stitching direction, for a short stretch of 30-70mm on the workpiece. The mechanism allows edges to be seamed round curves of a very narrow radius, without stretching or distorting the material.

Title: Laser beam apparatus for ballistic measurements - uses array of parallel laser beams to measure projectile velocity travelling across beams
Inventor: MICHEL DIETER
IPC: G02B27/09
Filed: 1976-03-13
Abstract: An apparatus is for measuring the velocity of a projectile such as a bullet, using an array of laser beams reflected back along their own course. A laser (L) produces a beam which is split by a prism array (T), typically a Wollaston prism, into a number of parallel accurately defined laser beams. The beams pass through two convex cylindrical lenses (Z1, Z2) and are then reflected back into another set of parallel paths by two inclined plain mirrors (U1, U2) after which they are focussed by a further lens (Z3e on to a photodetector (P). This feeds a signal to an amplifier (V), a triggering circuit (R) and a counter (Z). When a projectile (G) passes through the laser beams at right angles to them, two pulses are produced at the photocell output.

Title: Football boots with increased friction kicking surfaces - has fine rubber projections on sides of upper either integrally moulded or on attached strip
Inventor: DASSLER ADOLF
IPC: A43B5/02
Filed: 1976-11-15
Abstract: The sides (6) of the upper of a football boot are covered with a large number of small projections (7, 8). The projections are supported by a thin layer of woven material which is impregnated with rubber in which the projections are integrally moulded. The woven layer is either sewn or glued to the upper which is made of leather or woven polyamide. The projections (8) in the region of the heel are in the form of fine parallel ridges. The projections (7) over the remainder of the upper (6) are in the form of ver fine spikes projecting from small circular bosses. These projections give more control over the ball by increasing friction between boot and ball. In addition, by using rubber the surface is unaffected by wet weather.

Title: Filter protecting a ball valve sensitive to particles of grit - which interfere with its two supplementary control valves
IPC: F16K31/34
Filed: 1976-11-26
Abstract: The valve, which fits a WC cistern, is opened and closed by a diaphragm moving away from, and towards, a seating: the movements of this diaphragm are dependent on the pressure in the chamber behind it, which pressure is determined by two small supplementary valves, one in the rear wall of the chamber and the other in the diaphragm itself. The rear wall valve is operated by the float in the cistern. When it closes, pressure builds up in the chamber, and the diaphragm moves forward, closing first the mian valve and then the valve at its own centre. A filter is installed in the supply, upstream of the diaphragm, to protect the supplementary valves. The filter is in the shape of a thimble, with mesh panels let into the sides, and a flange at the bottom to hold it in place.
