Title: Respirable gas supply - by automatically controlled pure oxygen admission to pure nitrogen
Inventor: WINKLER DIETMAR ING GRAD
IPC: A62B7/06
Filed: 1978-08-25
Abstract: Respirable gas with a variable oxygen concn. esp. for the cockpits of fighter planes, is supplied by mixing pure oxygen and pure nitrogen in the proportions required. The two gases are evaporated separately from the liquid phase and mixed in their vapour state. This saves having to instal special purification apparatus for air extracted from the gas turbine compressors. It adjusts the gas composition depending on the varying flight altitude.

Title: Insulation of measurement transformer coil - has protective metal sheathing, connecting and protective tubes with insulating tape wound around it
Inventor: ALLMENDINGER KARL
IPC: H01F41/12
Filed: 1978-09-15
Abstract: The coil has a protective metal sheathing, a connecting tube and a protective tube on it for the coil connections, on which an insulating tape is wound. To produce a tapering insulating layer on the protective tube, the tape width is reduced by a cutter movable along the tube. The tube other end is brought to the connecting piece, and the protective tube insulating layer is connected to an insulating strip on the coil protective sheathing. The width of the insulating tape (4) is reduced at its other end also by a movable cutter, so that an insulating layer tapering at both ends is produced. Space between the insulating strip (5) and the tube (3) insulating layer is filled by a further insulating tape (7).

Title: Automatic contactless adjustment of precision contact springs - uses regulated distortion by heating with controlled energy laser beam
Inventor: MARTIN ROLF DIPL ING
IPC: B23K26/351
Filed: 1979-05-04
Abstract: The method of automatic contactors of precision engineering equipment is esp. applicable to contact springs and is realised simply and economically. A defined distortion of the part being adjusted is achieved without the application of force by using localised regulated heating. The thermal energy source is a laser whose light beam is directed to points of difficult access via deflection elements. These may take the form of mirrors or optical fibres. This method is applicable for contacts of all metals and organic materials. The thermal energy applied can be exactly controlled, thus facilitating accurate automatic adjustment. Because the heating and cooling times are short the distortion can be rapidly and continuously measured.

Title: Device for fitting to sail-boats to influence heel - is membrane either side of keel, selectively pushed out to predetermined extent
Inventor: PINZGER MANFRED
IPC: B63B41/00
Filed: 1979-09-19
Abstract: The sailboat fitting to influence their heel is a flexible membrane (13) fixed to the keel (12) on both sides between hull (11) and ballast weight (14). Gas or liquid selectively injected under pressure through passages (10) within the keel into the space (15) between it and the membranes pushes one of these outwards, altering the keep cross-sectional profile on that side. Alternatively, mechanical means can be used to achieve this. Horizontal webs (16), pref. flexible, fixed to both keel and membrane limit membrane movement to produce a predetermined outline. Holes in the webs permit fluid flow through.

Title: Finish polishing of recess machined by spark erosion - employing cast resin pad loaded with abrasive particles
Inventor: LOHSE SIEGFRIED
IPC: B24B35/00
Filed: 1979-10-20
Abstract: In giving a polished surface to a cavity or recess machined by spark erosion, the electrode is usually also used for the polishing process. A lapping or grinding medium is applied between the copper electrode and the work piece. It is proposed to employ a cast resin block for this purpose. The block is cast into the machined recess (2) in the workpiece (1). Shrinkage of the resin during the curing process gives sufficient clearance to enable the eccentric drive (8) to operate. This drive may be combined with a vertical drive (20) to enable both bottom and sides of the recess to be polished. The abrasive material may be loaded into the resin or placed between the resin block and the workpiece. The arrangement requires less driving power and reduces electrode wear.
Patent DE-2942892-A1 (DE)
Title: Combined IC engine and steam engine - uses steam produced by waste heat from IC engine to feed steam engine in same casing
Inventor: WUNDERLE GEORG
IPC: F02G5/04
Filed: 1979-10-24
Abstract: The engine is arranged so that the waste heat is used for generating steam which is used to produce further mechanical energy by increasing the heat-exchanger surface of the engine and by guiding the steam into a steam stage coupled to the engine. The steam stage is located in the same casing as the engine and is designed as a conventional steam engine. A reduction gear is located on the crankshaft and between the combustion engine and steam engine and matches the different expansion rates of the fuel/air mix and the steam. The entire system is thermally controlled, i.e. fuel feed, steam pressure and engine temp., such that the fuel supply can be increased or reduced or the steam engine utilised depending upon the power required and the ambient temp.
