Patent DE-2106851-A1 (DE)
Title: Fabric winding - using arm to direct material to vertically rotating hooked roller
IPC: B65H75/02
Filed: 1971-02-13
Abstract: The pivoted motor-driven arm, together with needle belts and roller brushes, carries the fabric to the required location for the hooks in their spiral formation to take up the fabric for winding, with an air space between layers. The roller rotation and arm movements are synchronised to allow for the increasing spiral as the fabric builds up. The reverse process is used to detach the fabric from roller hooks. The purpose is to automatic the fabric winding process when preparing the rollers to carry the material through a treatment process.

Title: Compression ignition engine fuel injection arrangement - has continuous delivery from pump metered into induction manifold
Inventor: MAYR THEODOR
IPC: F02M69/00
Filed: 1973-05-30
Abstract: The pump draws fuel from reservoir and conveys to pressure regulator which has diaphragm and spring operated by-pass to control pressure output. Under conditions of system demand the by-pass to reservoir is closed, but as pressure builds up due to fall off in demand, the spring is compressed lifting the valve from seating. Fuel from pressure regulator then supplies a metering and distribution valve operated by slider which simultaneously uncovers outlet ports to allow pre-determined quantity to flow into injection valves. The latter are made in two parts separated by a combined flat sealing disc and control diaphragm which is spring supported. The spring is housed in the lower component and is capped at top by diaphragm reinforcing plate and injector valve actuator.
Patent DE-2332125-A1 (DE)
Title: Pneumatic servo motor, using return springs - with piston-operated valve units moving in opposite directions
Inventor: TUGWELL JOHN
IPC: F15B11/06
Filed: 1973-06-25
Abstract: The motor contains a double-acting piston, separating two pressure chambers. A spring unit presses the piston in one direction. A valve unit supplies compressed air to one chamber, and thereby tensions the spring unit. In a pre-selected phase relationship of the piston, the valve unit transmits some of this air into the other chamber, and opens the first chamber to the atmosphere. The combined forces of the spring unit, and the compressed air acting onto the piston in the other chamber, complete the working cycle of the drive. Preferably, the motor contains double-acting twin pistons, moving in opposite directions. The pistons separate a common pressure chamber from two additional chambers.

Title: Shoe sole adhesive applicator contg - employs photoelectric sensor for adhesive applied to instep or combined sole
Inventor: SCHINDLER HERBERT
IPC: A43D25/18
Filed: 1973-09-07
Abstract: The application of the adhesive for joining the shoe sole depends on the size and shape of the shoe uppers and the folded over edges. A sensor is provided which establishes the limits for the application of the adhesive. This sensor is arranged in a certain spatial relationship with the toe of the shoe. The position of the adjustment of the sensor in relation to the shoe toe can be adjusted in advance. The adhesive is applied by a dispenser which moves along the shoe sole edge. The movement of the dispenser is determined by the setting of the photoelectric adjustable barrier. When the dispenser interrupts the light beam then it is stopped and returned to the starting point.
Patent DE-2346284-A1 (DE)
Title: Strip covering gaps between plates in corners and on walls - is made from elastomer and has longitudinal groove along which it folds
Inventor: DEHLEN BENGT LARS ARNE
IPC: E04F19/06
Filed: 1973-09-14
Abstract: For covering the gap between two flat plates a strip of approximately triangular section is used, with a deep groove along the centre of the strip. T-bolts are placed in this groove, to connect the strip to the wall. The faces of the strip which engage with the plates are at a slope so that the groove along the strip closes up when the strip is pressed into position. If the strip is use in corners, it is again of approximately triangular section. The angle which fits into the corner is larger than 90 deg. so that, when the strip is pulled into the corner by the fixing bolts, the groove which runs along the length of the strip again closes up.

Title: Multi-stage piston I.C. engine - has piston compressor stages operated by engine common crankshaft
IPC: F02B43/06
Filed: 1974-03-07
Abstract: The multi-stage compressor has a cooler between low and high stages. The second engine unit has a heat exchange unit where the exhaust gases are used to heat the compressed air from the first unit. The pre-heated compressed air is then fed via a three way valve where part of the hot compressed air is fed to a fuel metering unit proportional to engine requirements. The remainder of the combustion air is passed through a feed in the cylinder head to a sliding injector valve which opens to admit the fuel air mixture and the combustion air simultaneously into the combustion chamber. The piston head has a heat proof layer to prevent heat transfer to the lower piston parts.

Title: Brightness control for CRT with electrostatic deflection - has electro-optical coupler controlling transistor switch supplying brightness electrode
Inventor: SCHENK ERWIN ING GRAD
IPC: G01R13/26
Filed: 1974-05-27
Abstract: The brightness control, for a c.r.T. with electrostatic deflection, has the c.r.t.'s electrode (b) that determines the spot's brightness connected over a transistor switch (T) to a voltage divider's (R1, R5, R2) tapping (P4). An electro-optical coupler (OK) is connected to the transistor switch's base circuit and controls its conduction. The transistor's operating point is chosen so that two control voltages turn it on and off and thereby alter the spot's brightness from dark to light respectively. The voltage divider is connected between two reference voltages. The advantage of the circuit lies in its simplicity.

Title: Non-slip lead weighting cord for pleated curtains - has lead beads on cord encased in flocked textile covering
Inventor: BUENGER PAUL MAX
IPC: A47H23/01
Filed: 1974-07-06
Abstract: The curtain lead weighting comprises a row of lead beads (2) threaded onto a support cord (1) or the like with a small spacing between each bead, which is maintained by the slightly constructed shaped edge (3') of each bead. To ensure that the beads do not move about unduly when applied to the hem of a curtain the beading is provided with a flocked textile covering which is achieved by first coating the beading with an adhesive and then applying natural or synthetic fibres. This can be undertaken in a suitable flocking machine, possibly by means of static charging. The spacer sections (1') between each bead can also be suitably flocked which helps to keep the beads in position.

Title: Gyrator capacitive filter with large signal to noise ratio - has dependent voltage increased across gyrator to less than corresponding independent voltage increase
Inventor: GOECKLER HEINZ DIPL ING
IPC: H03H11/08
Filed: 1975-02-04
Abstract: The filter branch-off circuit has a capacitive gyrator replacing each coil. The gyration constants are so chosen that the dependent voltage increases across each gyrator are equal to or less than the corresponding independent voltage increases. The number of LC series resonant circuits designed into the filter, using equivalent conditions, is kept as small as possible. In designing a high pass filter, the elements forming one attenuation pole are coupled in a chain in such manner that the frequencies of the appropriate pole from filter input to output rapidly decrease in monotone manner, while increasing in case of a low pass filter design.
