IPC: B60H1/24
Filed: 1975-03-01
Abstract: The profiled console (10) is fitted to the floor of the vehicle between the front seats and contains two concentric air ducts. Stale air is drawn into the ducts behind the front seats, via perforated intakes in the rear and sides of the front seat. The air is drawn towards the front of the console where it passes a simple non-return valve formed by a pivoted flap. The airstream is deflected backwards into the outer concentric duct via sound-deadening material (15) in the end of the duct. The air is finally drawn out of the vehicle by exit slots under the vehicle in a line across the width of the vehicle under the front seats. Smaller, lateral ducts (21, 22) under the front seats serve for this. The lateral ducts double as front seat supports. The exit slots are in a position of low pressure under the vehicle, in a setting where exhaust fumes are no problem. The design of console prevents ingress of water and fumes as well as providing a quiet system.

Title: Energy-saving appliance for central heating systems - surplus boiler energy is transferred to hot water tank
Inventor: WIESS HANS
IPC: F24D19/10
Filed: 1975-03-06
Abstract: The appliance is for central heating systems with hot water tank and charging pump. When the system is on 'summer' operation, e.g. only water is heated, the energy of the over heated boiler is fed into the hot-water tank. When the programme has switched over to night-time operation, the heat energy stored in the boiler may still be fed into the tank. Alternately, the hot water circuit may be automatically interrupted during night-time operation. When the programme has switched over to day time, the heating water tank is rapidly charged and then when the minimum temperature is reached, the boiler is supplied with energy. When the boiler temperature has been reached, the heating is switched off, although surplus boiler energy is still transferred to the hot water tank.

Title: Economical silicon solar cells prodn. - useful for electricity generation in large arrays at terrestrial sites
Inventor: FANG PAO HSIEN
IPC: H01L31/068
Filed: 1975-05-20
Abstract: A solar cell having Si diodes supported by an electrically conductive Al substrate is formed by depositing and growing a thin layer of crystalline Si of specific impurity type and concn. on the Al, using the Al as a nucleation site for Si crystal growth and for auto doping of the Si, to form pn junctions performing photovoltaic energy conversions. Front electrodes and connection leads are secured to the device. The cells are about 10 mu thick (compared with 300 mu for a conventional cell) so although they are about 20% less efficient, they contain 30 times less Si. As efficiency is independent of minority carrier lifetime, crystal imperfections, mechanical damage and impurity contamination are less critical than in conventional cells. The cells can be economically mass produced.
Patent DE-2522916-A1 (DE)
Title: Illumination for colour negatives in copier or enlarger - uses distributed filters supplying low absorbent diffusors for stronger light
Inventor: HERRMANN ANSELM
IPC: G03B27/73
Filed: 1975-05-23
Abstract: The basic apparatus uses a single, broad filter for each colour tilted into the path of a eam of white light. Each colour component normally forms its own connected region of the filtered beam, and strong, ligh-absorbing diffusors are usually needed to blend the rays together to provide an even illuminated for the negative. Illumination is increased with the colour filters divided into narrow strips, with spaces between through which white light will pass when the strips are only partially tilted. The filtered beam is more broken, its colours more scattered, and milder, less absorbent diffusors will suffice, and narrow scratches on the negative will not show upon the print.
Patent DE-2525721-A1 (DE)
Title: Milking machine with vacuum in gap between teat and sheath - pressure difference on each side of sheath causes necessary adhesion in proportion to milk flow
IPC: A01J5/007
Filed: 1975-06-10
Abstract: The milking machine incorporated a vacuum unit, vacuum pipe, milk-container, milk pipe, collector, milk tube and a sheath enclosing each teat. The gap between the sheath and the teat is formed by a shaft-piece head with air-inlet and lip. The vacuum produced enables the pressure to be kept constant in order to keep the sheath on the teat. The difference in pressure each side of the sheath wall is regulated by the milk flow. The sheath may have elastic or rigid sides. An indicator on the inner wall of the sheath gives readings for controlling the pressure difference. A meter inside the sheath meters the air-flow. A vacuum indicator inside the sheath helps to regulate the pressure exerted on the sheath wall.

Patent DE-2546179-A1 (DE)
Title: Timing circuit for electromechanical switch - is used to minimise surce current when switching on transformer
Inventor: SCHACHER ROGER
IPC: H01H9/56
Filed: 1975-10-15
Abstract: The application is to circuits where the protection setting has to be near the full load value, as for example in train heating, and the surge current when switching on the transformer must therefore be limited. This is achieved by relating the switching instant to the charge on a capacitor. The closing relay coil of the switch is in series with an electronic switch and a contact. A small voltage is constantly applied to the coil via resistors and gives a measuring signal voltage comprising the drop across a coil and a ballast resistor. On closing the contact a capacitor is charged through resistors and the charge voltage measured on a divider.
Patent DE-2557395-A1 (DE)
Inventor: GLEISSNER GERHARD DIPL ING
IPC: G05F1/70
Filed: 1975-12-19
Abstract: In installations having high-power DC loads which are supplied via converters, for example DC drives in rolling mills, high reactive powers occur which cause an additional stress on the supplying three-phase network. Until now, static reactive converters (B) have been used in conjunction with capacitors (K), for example, in order to compensate for the reactive power. On the basis of this, it is proposed to use the converters (A, B; E, F), which are used for DC loads (M) anyway, to improve the reactive power consumption from the network. For this purpose, the required value of the converter which is operating as a reactive power converter (B), or the circulating current in converter circuits (E, F) in which there is a circulating current is controlled in such a manner that the primary of the transformer (T1; T2) which supplies the converters (A, B; E, F) absorbs an essentially constant reactive power. <IMAGE>
