Title: Submarine power supply - with catalytic high-pressure hydrogen peroxide/fuel reactors, diffusion cell and gas/water turbine
Inventor: GULDEN PETER
IPC: H01M8/0612
Filed: 1974-05-31
Abstract: A new propulsion system for submarines is based on a high-pressure gas reactor. A catalytic gas reactor serves for the reaction between fuel and H2O2 at high pressure. A diffusion cell separates H2 from the resulting products of reaction. A fuel cell feeds a steam generator for a turbine alternator. The waste gases of the reactor are passed to a propulsion turbine of the gas/water type which can be swivelled relative to the submarine. This power generating system is much smaller than that required by nuclear power systems. It does not require the extensive protective screens which are necessary for nuclear power reactors.

Patent DE-2519541-A1 (DE)
Title: Oil impregnated component cast into insulating resin - using resin-forming liquid of inter. density as barrier
Inventor: BALLMER WILLI
IPC: H01B17/60
Filed: 1975-05-02
Abstract: The Parent Patent describes a method of casting-in-oil-impregnated electrical components in a casting resin, in which the impregnated components are mounted in a surrounding mould, this mould is filled with a liq. completely surrounding the impregnated component and then a liquid casting resin is introduced into the mould so that as it rises, it displaces the liquid and finally completely expels it from the mould, the rate of introduction of this casting resin being suitably regulated. After the resin has set, the finished cast product is removed. In the Patent of Addition, the non-setting liquid (Fl), of relatively low density, and also the heavier resin-forming liq. (F2) are both displaced upwards by a third, still heavier casting liq. (F3), the last two component is introduced until the boundary surfaces liq. both possessing the same resin-forming functional gps. the third component is introduced until the boundary surfaces (F2/F1) and/or the boundary layers (GF2F1) between the non-setting liq. and the resin-forming liq. have been expelled from the region affecting the impregnated electrical component (2). The critical layers between the non-settling liq. and the resin-forming liq. have been completely removed from the mould and thus possible sources of weakness in the final casting are eliminated. By contrast, the boundary between the two resin-forming liqs. possessing the same functional gps. i.e. the layer (GF2F1), which itself possesses full resin strength, is the only type left in mould. In the final state, the casting liq. (F3) completely surrounds the electrical component (2) except for the small layer above it, which is of this non critical type. The resin-forming liq. (F2) may contain a contrast colour, so that the progress of casting can be observed. The density of the liq. (F2) is approximately halfway between the densities of the other two liqs.

Patent DE-2526499-A1 (DE)
Inventor: STREICH MARTIN
IPC: F25B30/00
Filed: 1975-06-13
Abstract: In order to transmit heat from ambient air to a working medium, a brine is heated in direct thermal exchange with air in a spray zone cooler (2), fed via a line (7) to a heat exchanger (9) in which the brine is cooled against an evaporating working medium of a heat pump circuit, and resupplied via line (1) to the spray zone cooler (2). In order to compensate the thinning of the brine by water absorbed from the air, a proportion of the brine is supplied through the heat exchanger (15) via line (13) to the evaporator (16) and subjected there to phase separation. The brine collecting in the sump is fed via line (17) to the brine circuit, while the water vapour/air mixture collecting at the upper end of the evaporator (16) is led via the compressor (19) to the condenser (20), separated in the eliminator (21) and removed from the system via lines (22 and 23). It is possible by means of this method for heat to be extracted from the ambient air even at low temperatures without the heat exchanger surfaces becoming iced. <IMAGE>

Title: Photometer attachment for diffused light measurements - of cultures in capillaries with two mirrors, one unilaterally blackened
Inventor: NEUHOFF VOLKER PROF DR
IPC: G01N21/51
Filed: 1975-07-08
Abstract: A diffused light attachment for a photometer consists of two mirrors. One, at 45 degrees to the photometer axis, has a blackened upper face. Its lower mirror face reflects the light, diffused by the sample to a second mirror, at a lesser angle to the axis. A photomultiplier is used to register the incident light. This makes standard photometers of spectrophotometers suitable for research into cultures grown in glass capillaries rather than in Petri dishes. Specialized instruments for diffused light measurements with such cultures are not required and merely require this simple and inexpensive attachment.
