Title: Dual fuel diesel engine - has high pressure alcohol pump with indirect connection to increase pressure of diesel fuel
Inventor: DIETRICH WERNER DR
IPC: F02M43/00
Filed: 1980-01-26
Abstract: The engine has alcohol injected as the main fuel with a smaller quantity of diesel fuel injected to initiate ignition. The diesel fuel is delivered by a low pressure pump (25) into a distributor (21). It enters a buffer volume (31) within the distributor. There is a spring loaded piston (33) within the buffer volume. A high pressure pump (16) delivers alcohol into a space on the underside of the piston (33) in the distributor. The alcohol flows through to an outlet (14) to its own injector and simultaneously raises the piston (33) to increase the pressure of the diesel fuel and discharge it (26) to its separate injector.

Title: Eye and spray protection screen for arc welding appts. - where light from arc or sound waves from human breath automatically move coloured glass over window in screen
Inventor: PFANZELT JOSEF
IPC: A61F9/06
Filed: 1980-05-06
Abstract: The screen includes a chassis plate contg. an open window. On each side of the window is a horizontal pivot bearing for a frame contg. a coloured safety glass. The glass normally covers the window due to the force of tension springs, but its frame can be swivelled by an electric micromotor so the window is completely open. In the housing of the chassis plate is a photoelement triggered by light from the welding arc to move the safety glass over the open window, so no harmful light rays or welding spray can reach the human welder. The chassis plate pref. also contains a microphone receiving sound waves caused by human breathing and automatically closing the window via an electronic circuit. Complete protection for the human face and eyes from harmful radiation and weld spray.
Patent DE-3019440-A1 (DE)
Title: Mosaic panel having dummy and active modules - which interlock via slots, grooves, holes and hooks obviating support frame
Inventor: MAIER GEORG
IPC: H02B15/04
Filed: 1980-05-21
Abstract: The modules are rectangular with square fronts. There are two types of module. The first type has dove-tailed slots in its four sides and the second type has dove-tailed ridges that slide into the slots. The first type has holes (4E) into which snap-action hooks on the second type locate. The slots and ridges prevent the modules moving laterally w.r.t. one another and the holes and hooks prevent them moving backwards and forwards w.r.t. one another perpendicular to the front face of the resulting mosaic panel. Each module is hollow and is open at one of its six faces. The open face may be made to face forwards or backwards depending on the way the module is fitted into the mosaic. Closure pieces (3A) with hooked legs (3B) close the open faces at the front or rear and their legs locate in further holes (4D) in the sides of the modules. No conventional support frame is required. The modules may or may not contain active components. An outer frame is formed by border pieces that mate with the outer sides of the outermost modules of the panel to form a flange or lip.

Title: Moulding embossed or perforated thermoplastic film lids - in single operation in tool using compressed air
Inventor: MERKLINGHAUS HORST
IPC: B29C51/32
Filed: 1980-08-07
Abstract: Shallow thermoplastic mouldings, such as lids, are produced by drawing and stamping out from film. Drawing is performed by compressed air on a male forming tool inside a chamber and a punch then stamps out mechanically, the finished article being moved into a stacking holder by an ejector when the chamber is opened again. After drawing, the chamber is vented, the moulding is mechanically postformed by briefly pressing against the chamber wall, it is then moved off the wall, the chamber is opened, and the moulding is pressed out into the stacking holder. Process enables mouldings to be embossed perforated in one operation, using one fixed tool.

Title: Mercury-vapour propulsion system
Inventor: UEBELE ANDREAS
IPC: H02N11/00
Filed: 1981-01-23
Abstract: The invention relates to a mercury-vapour propulsion system, in the case of which the special physical and thermodynamic properties of the mercury are used to produce a simple, economical and universally applicable drive system. The mercury-vapour propulsion system is distinguished by the fact that mercury is vaporised, compressed and mixed with magnetic particles, and the mercury-vapour/magnetic particle mixture is subsequently passed through a spirally curved tube system in whose interior a drive system is arranged which is provided with electromagnets or permanent magnets, and follows the rotational movement of the mercury-vapour/magnetic particle mixture. In this case, the mercury vapour is changed into the liquid state at the end of the spirally curved tube system, is separated from the magnetic particles and is subsequently vaporised once again. <IMAGE>

Patent DE-3122352-A1 (DE)
Title: High-back-resistance planar semiconductor component with lacquer coating
Inventor: MEINDERS HORST DIPL PHYS
IPC: H01L29/40
Filed: 1981-06-05
Abstract: A planar high-back-resistance diode, or a semiconductor component containing at least one such diode is proposed. In addition to the usual terminal electrodes, the diode also contains narrow metal strips which are applied to the oxide on top of the high-resistance zone of the p-n junction. The metal strips have to be positioned in such a way that they do not affect the spread of the space-charge zone when a reverse voltage is applied. For this reason, they should be situated if possible outside the space-charge zone on the high-resistance part of the p-n junction. Coating planar high-back-resistance diodes with lacquer for the purpose of passivation has hitherto presented substantial difficulties. The charges impressed on the silicon dioxide/lacquer boundary surface by the lacquer migrate under the influence of temperature and electrical surface fields. This ion migration results in polarisation at the surface of the lacquer-coated p-n junction, as a result of which the breakdown characteristic is impaired or destruction even takes place. The proposed metal-ring system acts as a barrier to this ion migration. Diodes having such rings exhibit virtually no change in their blocking properties after a hot reverse test (150 DEG C, 400 V, 20 hours). As a result failures can be completely avoided.

Title: Device for visual inspection (examination) of radial shaft sealing rings
Inventor: ZUR NIEDEN ACHIM DIPL ING
IPC: G01M13/00

Abstract: By contrast with the previously customary visual inspection devices for radial shaft sealing rings, the device according to the invention also permits inspection of radial shaft sealing rings with dust lip, as they are generally used nowadays. By interposing a conical optically transmitting, constructed as a rotationally symmetrical prism, between the light source and opaque cylindrical test mandrel, it is achieved that the dust lip is raised out of the beam path and the light is incident on the sealing lip to be examined in a manner parallel to the cylindrical lateral surface of the opaque test mandrel (diagrammatic sketch). <IMAGE>
