Patent DE-2604816-A1 (DE)
Title: Multi lobe piston rotary IC engine - has curved piston sides and rotating disc instead of valves
Inventor: HORSCH TRAUGOTT
IPC: F01C1/10
Filed: 1976-02-07
Abstract: The piston (11) rotates eccentrically in a chamber (2) with an even number of corners, one more than has the piston. The surfaces between the corners are curved towards the centre in both cases. The eccentricity (r) of the piston is such that the sealing strips (13-17) let into its corners are in permanent contact with the chamber walls, creating a number of separate spaces whose vol. varies cyclically as the piston rotates. Halfway between the corners in the chamber wall there are alternately spark plug recesses (22) and radial slots (23). The latter each have an inlet (25) and an exhaust (24) port in one end. These line up with slots in a plate sealing the end of the chamber, each slot extending halfway around the periphery.

Title: Carpet sweeper machine collecting heavy particles of dirt - has interacting brush rollers driven in opposite directions and forming closed space
IPC: A47L11/24
Filed: 1976-04-21
Abstract: The carpet sweeper machine has brush rollers which are mounted one behind the other.

Title: Stabilised suspended linear induction railway - has inclined tracks with planes meeting in centre of air gap
Inventor: TIEDCHEN HANS DIPL ING
IPC: H02K41/025
Filed: 1976-05-20
Abstract: The tracked linear induction system has two running tracks (2, 3) set to straddle the suspension support (1) and with the tracks tilted outwards. The wheels (4, 5) are similarly tilted so that the lines of action of the wheels meet in the centre of the airgap system for improved lateral stability. The vehicles can oscillate about the centre of the airgap without affecting the drive. Loose tolerances can be used for the airgap components. Any wear on the wheel tyres just drops the centre of the airgap accordingly.

A second reservoir (54) for domestic hot water (30) is heated by solar panels (46) and by a secondary energy source (74) which is controlled by a control unit (70) with temperature sensors (66, 68) in the flow and return circuits.
Patent DE-2631488-A1 (DE)
Inventor: SCHUBERT OTTO
IPC: A47B88/493
Filed: 1976-07-13
Abstract: The chemist's chest contains drawers (2) which can be displaced along guides and have an inclined base (3). The base of the drawer slopes, transversely to the push-in direction, from one, upper side edge, over the entire draw width, down to the other, lower side edge. The drawers are guided only along their higher sides and the drawer projects freely downwards beyond this guide. As a result, the goods (5) lying on the inclined base can be easily viewed from the side and they can also be easily removed, the remaining goods then sliding automatically into place. <IMAGE>

Title: Vehicle wash for underside of chassis - has support grid above shallow pit which houses spray nozzles in array wider than vehicle
Inventor: DUERR BENEDIKT
IPC: B60S3/04
Filed: 1976-09-24
Abstract: The vehicle wash bay has a grid over a series of vertical washing jets which project water under the chassis. The grid is wider than the vehicle so that the wheels and wheel arches are sprayed from both sides. Extra jets are positioned at the edges to ensure efficient cleaning of the arches. The jets are arranged in a shallow pit under the grid, so that the spray distance is kept small, for effective loosening of the dirt. The jets are further enhanced by positioning them on a series of transverse distribution pipes.

Title: Billiard cue for playing miniature billiards - has spring loaded plunger in handle to control impact energy
Inventor: PEROVIC MOMCILO
IPC: A63D15/08
Filed: 1977-01-31
Abstract: A billiard cue is in the form of a tube with a sliding plunger (2) which projects from the tapered end and is provided with a tip (2c). The plunger has a collar (7) which abuts against the spring (5). A short rod (9) attached to the plunger (7) projects radially through a slot (8) in the wall of the tube.

Title: Type levers impact damping system on typewriter - operates using pneumatic piston and cylinder common to all levers
Inventor: HILGENDORF REINHOLD
IPC: B41J7/22
Filed: 1977-06-29
Abstract: In a power-driven typewriter having type levers swung against the platen, each type lever has an operating lever which, toward the end of its actuating movement, abuts a rail common to all the operating levers. The rail is connected to a pneumatic piston and cylinder damping device. The cylinder damping device reduces the momentum of the type lever before the moment of impact, and thus reduces noise and wear. The rail may act on the piston through a double-ended lever whose ratio is varied. This causes a variation of the stroke of the piston according to the impact requirements of particular letters.

Title: Accessing terminal for service information by telephone - involves dialling terminal number followed by own number which is stored for call-back by terminal
Inventor: STANKE JUERGEN DIPL ING
IPC: H04M11/06
Filed: 1977-07-07
Abstract: A telephone, which may be a conventional, unmodified telephone from a telephone network, serves as the terminal for transmission system for information, esp. information as to the use of services e.g. public transport. After the dialling code of the telephone has been selected by a subscriber, he dials his own number which is converted into a digital signal, in a decoder (2.1) for storage in a process computer (2.2). Subsequently, after storing the signals, the unit calls the subscriber back by means of an automatic dialler to verify the instructions. In addition the terminal may be provided with a tape recording unit to store the data transmitted by the subscriber who may use the dialling unit of his telephone as a data transmission device.
Patent DE-2736595-A1 (DE)
Inventor: BAUMGARTNER HANS ULRICH DIPL P
IPC: G01L1/14
Filed: 1977-08-13
Abstract: A force (6) is introduced via a force-introducing block (7) onto a dielectric (8) which is pressed against a stop (11). An AC voltage source (5) transmits a dielectric displacement current through the dielectric (8) by means of an electrode pair (1 and 2). The mechanical tension caused by the force (6) in the dielectric (8) produces an anisotropy of the dielectric properties of the dielectric (8). The symmetry of the distribution of the displacement current is disturbed, and a compensating current flows from the dielectric (8) via a second electrode pair (3, 4) and a measuring instrument (9). The current through the measuring instrument (9) is then a measure of the force (6). <IMAGE>

Title: Signalling lamp circuit with DC=DC converter - reducing 60 volt supply to few volts for high current incandescent lamps via transistor switches
Inventor: NEUMANN DIRK DIPL ING
IPC: H05B37/02
Filed: 1978-03-23
Abstract: The signalling lamp circuit controls the switching of lamps whose available supply is roughly 60V. The supply is reduced using a d.c. /d.c. converter (1) to a few volts. The signalling lamps are high-current incandescent lamps (2) and each is in series with a transistor switch (3). The bases of the transistor switches are connected via a resistor and a signalling switch to the 60V supply. The current supplied to the bases of the transistor switches is of the order of a few mA. The advantage lies in reducing the power consumed by each lamp and in the heat evolved.
