Title: Unipolar to bipolar converter for rectifier pulses - has single transistor with control volts applied to base to alter output amplitude
Inventor: PELTZ GUENTHER
IPC: H03K5/003
Filed: 1976-02-19
Abstract: The unipolar-to-bipolar converter is for rectangular pulses. It may be used in electronic organs. It produces bipolar output pulses whose amplitude can be altered by a control signal. The unipolar input pulses have constant amplitude. The input pulses (UE) are applied to the emitter of a transistor and the output pulses (UA) taken from the transistor collector. The transistor has both emitter and collector resistors. The control voltage (US) is applied via two separate resistors to the transistor base and its collector. The base has a single biasing resistor. All the resistors bear specified relationships to one another.

Title: Screw spanner with auxiliary mechanism - has movable wedge in jaw allowing spanner to be swung back after each working movement without releasing grip
Inventor: STEFFE MICHAEL
IPC: B25B13/46
Filed: 1976-03-05
Abstract: The screw spanner has an auxiliary mechanism allowing the spanner to be swung back after each tightening or loosening movement without releasing the grip on the bolt head or nut.

Title: Simple drive mechanism for vertically adjustable blackboards - comprises hydraulic motors connected in parallel and synchronised by pulley-cable guide
Inventor: WEIDMANN ULRICH DIPL ING
IPC: A47B97/06
Filed: 1976-03-11
Abstract: The drive mechanism for raising and lowering large blackboards and the like comprises two separate hydraulic motors (8) which both have the same torque and are hydraulically connected in parallel for moving the board up or down by means of drive cables or chains (5) which are suspended from the sides of the board. One parallel guide mechanism which is attached to the board and operates with pulley (10) and cables (11) ensures the synchronism of the motors thereby simplifying the structure of the mechanism. The counter weights (7) are suspended from the drive cables or chains (5) whereby it is preferable for a second blackboard to act as the counterweight for the first.

Title: Blow moulding thermoplastics bottles - using adjustable upper and lower stops for blow mould driven by threaded spindles
Inventor: NAUMANN WILLI
IPC: B29C49/34
Filed: 1976-05-18
Abstract: The half-moulds are moved continually downwards by the rotation of threaded spindles after they receive the blanks. These threaded spindles pass between the half-moulds. The bottom limit of travel of the blow moulds is provided by transverse beams, while the top limit of travel is provided by transverse beams, forming part of fixed frames. The instant at which the mould is closed, after the direction of movement of the tongues towards the blow head has been changed, must be accurately determined; the arrangement described with top and bottom cross-beams makes this possible. To change the appts. for the production of blow mouldings of a different height, it is only necessary to alter the distance between the cross-beams.

Title: Multi-lane road layout - has overtaking lanes narrower than other lanes, to discourage prolonged stay
Inventor: BRUEGEL GERHARD DIPL ING
IPC: E01C1/00
Filed: 1976-09-28
Abstract: The road, with at least one overtaking lane, is of the motorway type, with four or more traffic lanes and a centre stirp between the two directions of travel. It is designed to make driving on the normal lane relatively more pleasant, so that the driver is encouraged to leave the overtaking lane as soon as the overtaking process is completed. For this purpose the overtaking lane is narrower than the normal lane, or lanes. Where there are four lanes, the inner ones are narrower than the outer ones. The respective widths of the overtaking and normal travel lanes are 3.50 m and 3.75 m. Where there are six or more lanes, they may grow progressively narrower towards the centre.
Patent DE-2643987-A1 (DE)
Title: N-Channel storage FET with one or more gates - has semiconductor region insulated by charge reversing region from both main path connecting regions
Inventor: ROESSLER BERNWARD DIPL ING
IPC: H01L21/265
Filed: 1976-09-29
Abstract: The storage field-effect transistor is intended for programme memory of a telephone exchange system. It has a floating storage gate surrounded completely by an insulator. For the charge reversal of the storage gate are utilised highly accelerated and heated electrons in the transistor conductive channel. Due to the heating the electrons overcome the energy threshold, owing to an electric field effective in the source-drain direction. The acceleration is initiated by a channel injection which is used for programming, i.e. charging, of the storage gate. After charting, the gate affects by its negative charge in a current restricting manner the source-drain path, as in 2445137. The semiconductor region (BX) is formed by a charge reversal region, insulated from both main connecting regions (SD). A capacitor strip (L) is separated from the charge reversal region by an insulating film, thinner than that separating the storage gate (G1).

Title: Detachable picture frame stand with fold-away rest position - is held against rear-wall of frame by retaining plate and lug
Inventor: REIM PAUL
IPC: A47G1/14
Filed: 1976-09-30
Abstract: The detachable picture frame stand can be used with various picture frames where it is held in position by a flat rectangular retaining plate at any point along a groove in the rear wall of the frame by means of a resilient holding lug. When the stand is in the operative position the lower peripheral part of the retaining plate sits in the groove at the back of the frame whilst the opposite peripheral part sits beneath the resilient lug where it is braced against the back wall of the frame. When not required, e.g. when the picture frame is mounted on a wall the stand can be easily folded left or right into its rest position where it then engages with the lateral peripheral strip of its retaining plate and lies flat against the rear wall of the frame where it is clamped as in its position of use.

Title: Mono-ski with pivoted steering board - can be controlled by skier placing his weight in correct position
Inventor: STUMM FRIEDRICH VON
IPC: A63C5/03
Filed: 1976-10-19
Abstract: The mono-ski has the undersurface divided into separate zones. The central zone (6) is flat with the side zones (13) inclined at an angle of 8 deg. The cross-section through the side zones has the form of a saw tooth and metal strips (12) are attached to the steep side of the tooth. In addition the mono-ski is steered by a steering board which is pivoted to the main board and controlled by the manner in which the skier places his weight on the ski. This method of steering obviates the need for control cords or for swaying of the body from side to side.

Title: Spinning unit having suction units in drums - with permeable mantles to collect fibres and form a yarn with low consumption
Inventor: TURK HERBERT
IPC: D01H4/16
Filed: 1977-03-30
Abstract: In a yarn spinning process, the fibres are collected on the permeable mantle of a rotary drum near the opening of an internal suction unit paralle to the drum ends forming a defined zone of underpressure against the inner surface of the mantle. The air pressure pattern is adjusted to give a cascade-type decrease in pressure from the zone where the sliver is broken into loose fibres to the point where they reach the suction unit, so that: P1>P2>P3>Po. In the inequality, P1 is the air pressure in the flow channel, P2 is the air pressure in the zone where the fibres pass freely between the opening of the flow channel and the yarn formation line, P3 is the air pressure in the suction unit. Po is the atmospheric air pressure. The air consumption is reduced without impairing the stability of the spinning process.

Title: PTC thermistor fuel supply monitor - has extra temp. sensor to eliminate temperature dependence
Inventor: BONNET KARL FRIEDRICH DIPL ING
IPC: G01F1/696
Filed: 1977-04-26
Abstract: The unit is for continuously evaluating the instantaneous fuel demand of IC engines, esp. vehicle engines, and depends on a heated PTC thermistor(2) fed from a voltage supply(10) and mounted in the fuel pipe(3). The cooling effect depends on the rate of flow, and hence the latter is measured by the power supplied to the thermistor. A temp. sensor(6) is also mounted in the fuel pipe and is coupled to a differential amplifier(7) which gives an output signal dependent on the difference between the measured temp. and a standard temp. for the PTC thermistor. The two signals are fed to a divider circuit(5) which gives an output dependent only on the fuel demand and not on the fuel temp.
