Title: Compression ignition engine combined fuel pump-injector - has electromagnetically operated piston in pump cylinder with injector valve opening in flow direction
Inventor: THOMA FRANK DIPL ING
IPC: F02M51/04
Filed: 1974-04-23
Abstract: The injection mechanism is of the type used in combustion engines running on fuel mixture, to maintain accurate repeatability when very small amounts of fuel are injected. The mechanism combines an injector valve with a pump in one unit. The pump comprises a piston which is moved in the direction of injection by electromagnetic means. The injector valve is arranged at the end face of the pump cylinder and preferably opens in the direction of injection. The piston stroke may be limited by a fixed stop. There may be an adjustable stop to limit the piston stroke in the direction against the flow due to spring force or fuel pressure.

Title: Controlling movement of adjustment piece moving element - with position and traverse required-value indicator per co-ordinate axis
Inventor: TIETZE ECKART DIPL ING
IPC: G05B19/40
Filed: 1974-04-26
Abstract: The process tool is controlled by a programme on a data medium and is designed to facilitate fast traverse from point to point along a predetermined course without inhibiting precision. For each co-ordinate axis, a position required value indicator and a traverse required value indicator are provided, the traverse required value being converted in a sieve multiplier into a series of impulses. These are fed to a regulating circuit whose time constants are adjustable to a desired value. The output signal of the regulating circuit is fed to a counter which compares with the contents of the position required-value register and to a phase counter which delivers to the stator windings of a step motor.

Title: Non-deformable composite weatherproof tabletennis table - comprises chipboard blocks stuck in staggers on aluminium plates
Inventor: NEUMANN RUDOLF
IPC: A47B25/00
Filed: 1974-06-05
Abstract: The weatherproof table tennis table comprises blocks of chipboard stuck onto one or between two aluminium plates. These blocks are preferably cut into squares or rectangles and then stuck on the plate in a staggered pattern so that the plate cannot warp since there must be some air between the blocks. However if the blocks are stuck on both sides of the aluminium plate then they need not necessarily be arranged in staggers.
Patent DE-2428958-A1 (DE)
Title: Bullet proof speech transmission channel in cashier desk window - has inclined edge walls and channel profile for catching bullets
Inventor: STROBL GUSTAV LORENZ
IPC: E06B7/30
Filed: 1974-06-15
Abstract: The speech transmitter is used in a wall made from bulletproof glass and it is used for box office and bank cashier windows. The speech opening is also protected against bullets. The speech channel is formed by deflecting members arranged at an angle. This arrangement is used also to ensure that fragments of bullets which are formed when a conventional bullet impinges against a deflecting wall cannot pass through the protection arrangement. The deflector plates (6, 7) enclose the edges of the bulletproof galss panel (2). Into the channels formed by the projecting deflector ribs is placed an additional profile which forms an enclosed channel (13) between the deflector plates. This enclosed channel (13) acts as bullet stopping and catching chamber. The fragments of the bullets with lead cores are deflected by this additional profile so that the fragments are slowed down and they are not able to penetrate to the other side of the window.
Patent DE-2431901-A1 (DE)
Title: Transfer system for glass plates - individual plates lifted via two suction points in arc or angled
Inventor: HEGERFELD KARL
IPC: B65G49/06
Filed: 1974-07-03
Abstract: The glass plates stand in a stack, and are moved onto a horizontal table, using a suction force, applied to the outer plate surface. The upper plate on the stack is seized at a point on its upper and a point on its lower half, and by lifting via an upper suction point, is moved in a concave arc, resp. angled relative to the stack. The plate is moved to above the horizontal table, and, by being swivelled through an angle of 90 deg., brought into a position parallel to the table. The plate is then deposited on the table, the contact surface being uppermost. An outwardly directed force is applied to a suction point near an upper corner. The force is sufficient to raise the plate, and overcome the adherence to adjacent plates in the stack.

Title: Temperature sensitive switch - has piston moved by expanding material to operate snap action switch
Inventor: SAUR ROLAND
IPC: H01H5/06
Filed: 1974-09-20
Abstract: This switch unit consists of a gas-tight housing with contact pins in its base. A temperature sensitive element is sealed within the case and has a container for either gas or liquid that moves a piston as it changes volume. The piston (10) causes a lever (6) to operate a mobile contact of a changeover switch which has a snap action due to a spring (7). The switch parts are connected to the base contact pins. The spring causes the piston to return as the temperature falls and the liquid volume decreases. This improves existing design by having simple piston return mechanism and by having the facility of achieving temperature control by deforming the liquid container externally.
Patent DE-2455123-A1 (DE)
Title: Safety seal for gas side of gas and liquid pressure vessel - sealing plug is located in depression in vessel convex wall
Inventor: SUGIMURA KAZUO
IPC: F15B1/08
Filed: 1974-11-21
Abstract: The vessel is divided by an elastic membrane (2) into a section (3) in which liquid collects under pressure and a section (4) filled with compressible gas and sealed by a tapering plug. The plug, is located in its soft-metal sheath (8) in a depression (5) in the wall of the vessel. Under increasing pressure the depression will flatten, causing the wall of the vessel to hold the sheath (8) more tightly on the inside but less tightly on the surface. Eventual failure will take the form of a slow leak round the sheath, rather than a forcible explusion of the plug.
Patent DE-2459279-A1 (DE)
Title: Coupling link for snow chain - with flat oval link to slide through side strands and secure cross chains
Inventor: MUELLER ANTON
IPC: B60C27/06
Filed: 1974-12-14
Abstract: The snow chain is manufactured in a simple, economic manner by using side chains (1) made from thin, flat, oval links (3) of welded construction. Such chains are available in any lengths. The cross chains are made from similar links (5) of a thicker design, but with the same link length. These are stronger to provide good wear resistance. The cross chains are linked to the side chains simply by including special coupling links (6) which are slid through the links of the side chain, and which are secured by having short links (8) on the other side of the side chain. The thickness of the coupling links is such that can slide through the side links but cannot twist in them.

Title: Water vapour admixture to combustion engine fuel mixture - uses exhaust heat to evaporate water, admits vapour downstream of carburettor
Inventor: LOOS SEN JOSEF
IPC: F02M25/022
Filed: 1975-08-06
Abstract: Systems for combustion engines utilises the heat contained in the exhaust gas to evaporate water or an aqueous mixture and feeds the water vapour so formed to the fuel/air mixture, thereby making it possible to use lead-free or low-lead fuel in a high compression ratio engine. The system can be applied to already existing engines without major modification. The vapour may be drawn into the inlet manifold by the vacuum present therein. The water may contain chemicals which promote combustion and assist in purifying the exhaust gas. The exhaust manifold may have evaporation ducts, and may be designed so that it can replace an existing manifold.
