Title: Hybrid transmission for vehicle - with variable epicyclic gearing between primary engine and wheels with intermediate electric motor
Inventor: KOERNER HELMUT
IPC: B60L50/16
Filed: 1974-07-16
Abstract: The primary engine (1) drives the wheels (10) via a variable epicyclic gearing (3) which enables the engine to run at its optimum speed for most efficient torque transfer. An electric motor (2) is connected into the transmission chain in such a way that the motor can be used to drive the system, with suitable reduction gearing to eliminate the need for massive electric motors, and to act as a transmission brake for regenerative braking. A hydrostatic drive can be used to replace the gearing, whilst the electric motor is provided with an accumulator (11) to store the power.

Title: Artificial tooth recessed in base - for firm anchoring into base material without danger of snapping
Inventor: MOENKMEYER ULRICH
IPC: A61C13/093
Filed: 1974-10-12
Abstract: Two individual recesses (17, 18, 19) are formed in the base of the tooth (11, 12, 13) and separated by a strip (14, 15, 16) which connects the front surface to the back of the base. The base material anchors firmly into these recesses rather than with the usual peg method which can snap off very easily. Pref. the recesses are of oval cross section and open towards the side edges of (21, 22, 23) the teeth. The surface area of the mass of base material enclosing the tooth and its anchoring is greater than the surface area of the raised section at the back edge of the tooth thus providing large surface area contact for good adhesion.

Title: Force measurement transducer producing alternating voltage signal - has force dependent frequency by use of balance mechanism
Inventor: NUERNBERGER WILHELM DIPL ING
IPC: G01L1/16
Filed: 1975-07-30
Abstract: The force measurement transducer uses a force tube and a balance mechanism associated with a resonant circuit, which produces an electronic signal with a frequency dependent on the force concerned. The mechanism consists of a rod (5) mounted inside a torque or force tube (2) one end of which is attached to a rigid wall (1). The rod extends through the wall to a sprung balance mechanism (7, 8, 9) which is in turn connected to a wire (10). The tension in this affects the resonant frequency of an oscillator which feeds a coil (12, 13) associated with the wire (10). An alternative form may use a piezoelectric crystal (14), instead of the tension wire.

Title: Semi-automatic design procedure for logic networks - uses computerised final design stage in which formalised code is adopted to produce final logic diagram
Inventor: KOTTER KARL-HEINZ DIPL ING
IPC: G06F17/50
Filed: 1975-07-31
Abstract: The semi-automated design procedure is for certain types of electronic network, particularly logic networks, in which the final specification of the network including its component parts, is done by a computer program. The design procedure consists of three distinct stages. The first entails a flow diagram which describes informally what the network is required to do. A second, formal flow diagram is then constructed using a number of standard symbols to describe timing or clocking points, registers, feedback loops and so on. This is listed in a formalized code and fed to the computer which produces a final logic diagram complete with element specification and interconnections.

Title: Spooling machine with threading aid - has spool arranged on arm to provide axial movement during rotation
Inventor: BURKHARDT KLAUS
IPC: B65H65/00
Filed: 1975-08-04
Abstract: The spooling machine is for the winding of one or more threads, with a spooling spindle to take spool covers with either the spindle or the cover fitted with thread pick-up devices. The machine also includes a thread changer to facilitate the thread build up during the winding process. The spool spindle with empty spool covers lies within the space circumscribed by the swivel movement of the thread placing arm. The turning axis for the thread placing arm is positioned in relation to the spool spindle axis so that it crosses the extension of the spool spindle axis. This produces an axial movement component for the threads to be wound in relation to the spool spindle.

Title: Oil scraper piston ring - has valve assembly along cylinder wall diverting oil into piston space
Inventor: CHARZINSKI HANS-PETER DIPL ING
IPC: F16J9/06
Filed: 1975-08-12
Abstract: The oil scraper piston ring design is for use on internal combustion engine pistons. The piston ring (4) is fitted in a groove (3) of the piston wall and has circular rims (6, 7) for the oil wiping function. The contact between the cylinder wall and ring is maintained by spiral spring (5) pressing the ring radially outwards towards the cylinder wall (8). The piston wall has a number of holes (20) located at the top part of the piston groove (3) and leading inside the piston. Inside the piston the holes are closed-up by spring loaded ball valves, which allow oil pressure relief into the piston hollow but not in the opposite direction. Alternatively, the valve can be arranged within the thickness of the piston ring. The valve can be a non-return flap on the inner surface of the hollow part of the piston.

The insert is pref. located directly below the surface of the tile and may consist of metal sheet, perforated plate, mesh, metal fabric, loose pieces of metal, or powder. The surface of the tile may possess a profile near the insert. In the pref. mfg. process, the metal insert is coated with a material which burns at the baking temp. of the tile and is inserted in the mould used to mfr. the tile. It is no longer necessary to drill holes in the tiles or to use adhesives in attaching fittings. The fittings, e.g. hooks, are provided with a magnet which adheres to the tile due to the metal insert.
Patent DE-2545798-A1 (DE)
Title: Idling control for automatic transmission - with drive disconnected at idling speed and with vehicle stopped
Inventor: KUGLER ARTUR
IPC: F16H61/20
Filed: 1975-10-13
Abstract: Sensors (6, 7) on the engine output shaft, and on the propeller shaft (5) monitor the engine speed and road speed. A simple control circuit (8) disconnects the transmission if the road speed and engine speed both fall below set minima. This relieves the transmission of drag, when the vehicle is temporarily stopped, and increases the life of the torque converter. The engine speed sensor can be replaced by a simple throttle position sensor. For transmissions in which the first gear is set, with the vehicle stopped, the control circuit provides an inhibit signal to prevent the gear from being set until the engine speed picks up, irrespective of the setting of the gear selector. The system reduces fuel consumption and exhaust emission.
Patent DE-2545920-A1 (DE)
Title: Computer data error correction circuit - uses parallel connected XOR, OR and AND gates to process data strings from two operands
Inventor: TSUI FRANK DR
IPC: G06F11/10
Filed: 1975-10-14
Abstract: The error correction circuit for a computer installation utilises a comparison system for two strings of data-bits (aj, bj, 5=0, 1, .....J-1) for tin operands (A, B). The data strngs pass through a gate control section and split into sections passing through XOR, OR and AND gates. Each group of data on passing through the second set of gates is attached to a parity bit to form an FCC (ERROR corrected code) group. A second parity bit is generated for each corrected string to transmit the corrected data to the next stage of the system. The sequence of checks is carried out in conformity with a decision table.

Title: Fixture for hydraulic piston on rod - has step to allow simple valve plate to be mounted on piston
Inventor: OLBERTZ WILFRIED
IPC: B23P11/00
Filed: 1975-10-27
Abstract: The piston for a vehicle hydraulic telescopic damper is mounted with its central bore over a turned down section (39) of a piston rod (40), until it sits firmly against a shoulder (41) on the piston rod. The turned down section of the piston rod is provided with a collar which can be forced round to form a rim (44) by a press tool. This secures the piston on the rod. In pistons as used in hydraulic telescopic dampers, the piston is provided with valve openings. This method of attaching the piston to the rod takes up little room and makes it possible to use a valve plate (48) of simple shape.

Title: Variable curved surface projection screen - has flexible membrane curved by gas pressure to maintain symmetry at different radii of curvature
Inventor: HOLZEL THOMAS M
IPC: G03B21/56
