Patent DE-2345844-A1 (DE)
Title: Hazard warning system for car - with selectively fired coloured flares, visible for greater distances than flashing lights
Inventor: PETROV PANAJOT
IPC: B60Q1/52
Filed: 1973-09-12
Abstract: The rear of the car is fitted with a compact tubular warning cylinder which holds a number of different coloured flares. These are selectively fired from dashboard selectors and project the flares rearwards into the air before they ignite. They provide a warning system, with different colours signifying different degrees of hazard, with the flares instantly visible to following traffic, over a greater distance and even in poor visibility. The system is particularly useful to prevent multiple collisions on motorways.

Title: Petrol pump with counter mounted on filler nozzle - wires incorporated in outer layer of delivery pipe
Inventor: VIESSMANN FERDINAND
IPC: B67D7/42
Filed: 1973-12-19
Abstract: A fuel dispensing machine for a garage or petrol pump also makes use of a counting and indicating instrument incorporated in the nozzle held by the user so that the contents of a tank being filled are more readily determined. The connecting wires between the instrument and the petrol pump or central calculating position are moulded into the outer wall of the filler pipe or in an alternative design, are incorporated in a layer which is afterwards applied to the outside of the filler pipe. Since the amount measurement and the actual filling of the vehicle tank can be simultaneously observed the risk of overflowing is avpoded.

Title: Endless belt tree trunk debarker
Inventor: HAERDTLE WILHELM
IPC: B23Q7/03
Filed: 1974-02-06
Abstract: Tree trunk debarker has a tool assembly that is displaceable lengthwise of the trunk relative to a machine bed, with roller elements driven in the same sense and perpendicular to the trunk, located on both sides of the trunk and carrying it between them, to rotate it during processing. The roller elements consist of endless revolving bands, belts, cables or chains conducted over both sides of the trunk and also centrally beneath it, on deflecting or drive wheels so that the sections carrying the trunk are directed obliquely outward on the sides of the trunk. These form between them a receptacle lengthwise of the trunk, tapering downward in a V tape, for the trunk. The roller spacing needs no adjustment for a wide range of trunk sizes.

Title: Hooked removable clothing button - has button hooked into base plate on garment and held by removable central pin
IPC: A44B1/34
Filed: 1974-11-14
Abstract: A button plate is on a base cone which is split into two parts. Through the plate and cone a bore to take a shaped pin. Fixed to the base of the pin is a collar so that when the pin is not fully in position the top of the collar is held behind a shoulder at the top of the bore so that the pin cannot be removed from the button. When the pin is in position the base of the collar has its angled edge pushing against an angled shoulder at the bottom of the bore so that the two halves of the base cone are forced outwards, ensuring that the collar round the outside of the base of the base cone halves hooks into the base plate which is fixed to the garment. The pin is locked in place in the button by a beading which is held behind the shoulder at the top of the bore.

Title: Twin cylinder two stroke IC engine - has segmental pistons reciprocating in circular arcs in circular cylinder
Inventor: TWACHTMANN FRIEDRICH
IPC: F02B53/10
Filed: 1975-01-29
Abstract: The engine has a cylindrical casing with inlet ports and discharge ports. An internal projection fits against an oscillating output shaft and divides the cylinder interior into two working spaces. The shaft has transverse curved passages through it and carries extended curved arms which form the pistons. Each piston divides each working space into two parts which vary in volume as the piston oscillates with the shaft and are connected at the correct parts of the cycle by the transfer ports formed by the passages in the shaft. Each cylinder contains a sparking plug. The oscillating shaft projects through one one face and the oscillating movement is converted into a continuous rotation by a rotary crank mechanism.

Title: Variable length data block transmission system - has transmission nodes each with selection of next transmission path of data block
Inventor: BUERGE HELMUT
IPC: H04L12/54
Filed: 1975-06-07
Abstract: The variable length data blocks, with a head part containing a destination marking are transmitted through a communication network with several exchange nodal points, containing buffer storage devices. The transmission is carried out without previous switching of a connection between the transmission and destination points. Each nodal point provides a selection of the next path section for the transmission of a data block and engages the same as soon as the head part has been received. The further transmission of the data block starts, when the next path section is available without regard of the data block being received entirely. Further transmission takes place until the block end characteristic with elastic buffering appears.
Patent DE-2527978-A1 (DE)
Title: Storm sewer basin - with central conical deflector and base gutter for solids collection and discharge without clogging
Inventor: POERSCH RUDOLF DIPL ING
IPC: E03F5/10
Filed: 1975-06-24
Abstract: A storm sewer basin to retain rainfall run-off has in the centre of the basin bottom a conical flow deflector. An annular gutter around the base of the deflector collects the solids entrained by the flushing action of the circulation and discharges them through a tangential outlet pipe. This utilises the water flow to improve the flushing action and prevents clogging of the outlet pipe by sludge deposits. To create a flushing action even in the dry season, a sickle-shaped guide channel directs the flow into the gutter.

Title: Strip waveguide with FET amplifier - with source drain and gate in SC chip and functioning in consequence of differential saturation wave velocity
Inventor: DOSSE JOACHIM PROF DR ING
IPC: H03F3/55

Patent DE-2543548-A1 (DE)
Title: Moving belt guided by two inclined pairs of rolls - exerting outward pull which varies to make belt self centering
Inventor: CRANDALL NELSON B EDENTON
IPC: B65H23/02
Filed: 1975-09-30
Abstract: A device for guiding a moving strip, band or belt of material comprises a pair of rolls which grips one edge of the band between them, the axes of these rolls being parallel to the strip but inclined relative to its centre line; the rolls are set at a predetermined angle to the centre line of the band and at a predetermined distance from the intended centreline position; both of these parameters are adjustable; one of the rolls is fixed while the other roll is pivotally mounted and biased by a spring towards the other roll so that they tend to pinch the band between them; the outer end of each roll, i.e. that furthest from the centre line of the band, has a facing of relatively hard, low-friction material, while the remaining extent of each roll has a facing of relatively soft, high friction material providing a good grip to the band. A pref. material for the outer region is hard synthetic fluorinated hydrocarbon, and for the softer facing an elastomeric, rubber-like material, pref. polyurethane. In the pref. embodiment, there are two such pairs of rolls gripping opposite edges of the band and both inclined to the centre line, thus constituting an arrowhead formation so that the two edges of the band tend continuously to be pulled outwards. The appts. is self-centering when two such pairs of rolls are used; as soon as the band moves, for example, towards the right in the figure, its edge comes between the two hard facings, thus immediately forcing the rolls slightly apart and relieving the pressure which their soft facing apply to the band; the pull of the opposite pair of rolls on the other side of the band immediately restores it by pulling it back between the soft facings of the rolls. Thus the centre line of the band is kept along the desired position.
