Patent DE-3334839-A1 (DE)
Inventor: LUDOLF WILHELM
IPC: H04B10/00
Filed: 1983-09-27
Abstract: In a duplex optical transmission system in which the optical transmitter (3) and the optical receiver (2) of each terminal (1) of the transmission section are supplied from the same voltage source, the optical transmitter (3) and the optical receiver (2) of at least one terminal are connected in series with regard to the power supply, and the optical receiver (2) is combined with a booster circuit to form a receiver unit (13) whose power consumption is independent of the output voltage of the optical receiver (2). As a result, the optical transmission system is also suitable in a simple and cost-effective way for small feed currents and powers, and the transmitter output signal is not affected by fluctuations in the receiver output signal. A particularly expedient embodiment of the booster circuit consists in a current source (T2, R3), which is connected in parallel to the optical receiver (2) and is controlled correspondingly by the output voltage of the receiver (2).

Title: Turbine pump
Inventor: WIESER RUDOLF DR
IPC: F03B3/10
Filed: 1983-10-25
Abstract: The invention relates to a turbine pump, preferably for field irrigation and drinking water supply in tropical and sub-tropical developing countries. The novel unit is characterised by the simplicity and robustness of its construction. Some of its components (for example the housing parts) can also be manufactured in the developing countries. An essential advantage of the turbine pump lies in the fact that it can also be submerged in the event of flooding. As a result it is possible to install it also on dams of primitive construction (for example, earth construction), which can be constructed by the inhabitants themselves. The novel turbine pump can be used both as a small appliance on streams for supplying village communities and as a large appliance for pumping water in extensive tropical irrigation projects. <IMAGE>

Patent DE-3414973-A1 (DE)
Title: Ventilation system for a house
Inventor: KOMUSIN JOACHIM
IPC: F24F5/00
Filed: 1984-04-19
Abstract: In contrast to conventional ventilation systems, in which the outside air is supplied as fresh air directly to the incoming-air shafts, a new ventilation system is characterised in that the fresh outside air is conducted through an air chamber embedded in the earth before entry into an incoming-air shaft of the house. The air chamber makes the temperature of the air supplied to it the same as that of the earth surrounding it. In this manner, it is possible during insolation in summer to reduce the associated undesirable heating up of the house and in winter to raise the basic temperature without a cost-generating energy supply.
Patent DE-3418439-A1 (DE)
Title: Ribbed tapered sealing ring for flange joints
Inventor: BARTOS VLASTIMIL J DIPL ING
IPC: F16L23/18
Filed: 1984-05-18
Abstract: In order to exploit the bending of the flange plates as the bolts situated at the outside are tightened to produce more uniform distribution of the sealing pressure over the entire width of the seal, this ring was designed with a taper with the greatest thickness at the inside diameter and the smallest at the outside diameter. In another embodiment, the surfaces are parallel and the groove depths touch a tapered surface, with the highest point at the inside diameter. This gives rise to ribs of different height, the lowest at the inner and the highest at the outer periphery of the active sealing surface.

Patent DE-3533131-A1 (DE)
Title: Cover for the outer surfaces of motor vehicles with pressure-applying closure
Inventor: MAISENHAELDER SIEGFRIED
IPC: B60J11/00
Filed: 1985-09-17
Abstract: Window covers of vehicles parked outside have the tendency in the winter of allowing the car windows to ice up despite their being covered. These window covers must be attached, by means of fastening elements, to the body of the respective vehicle, the outer edges of the covers not being sufficiently sealed and water being able to enter between window and cover. Subsequently, on frosty nights the window can ice up. The invention eliminates these disadvantages in that a sealing closure Fig. 3, P. 8, 12 which is detachably arranged on the window cover presses the elastic cover in a sealing fashion against the car window in order to prevent water entering between window and cover. Icing up of the car window in the event of frost is thus excluded. <IMAGE>

Title: Anti-corrosive coating for metallic workpieces, especially for fine mechanical precision parts
Inventor: HELLWIG GUENTER DR RER NAT
IPC: B05D7/24
Filed: 1985-12-12
Abstract: In order to obtain anti-corrosive coatings functioning reliably over prolonged periods in the form of extremely thin protective coatings which do not affect the geometry of the workpiece, a conventional vapour deposition process is employed to apply a coating of low-molecular weight trifluorinated silicon compounds to the workpiece. The coating preferably has a thickness of approximately 2-10 nm and after the vapour deposition process is crosslinked by means of UV irradiation. The coating, which does not incorporate any water, largely prevents demixing and enrichment processes on the workpiece surface.
Patent DE-3545849-A1 (DE)
Title: Sealable screw connection
Inventor: BRIEM GERHARD
IPC: F16B35/04
Filed: 1985-12-23
Abstract: For a sealable screw connection comprising essentially a screw bolt and a nut, the invention proposes that the bolt 1 and/or the nut 8 have channels which are arranged such that a flowable composition, sealing composition, can be pressed, after the connection has been screwed tight, into cavities located within the connection. In this arrangement, the bearing surface of the screw head and/or of the nut may have radial grooves. This opens up the possibility of carrying out the sealing process of screw connections in an automated production sequence. <IMAGE>
Patent DE-3603482-A1 (DE)
Title: Adjustable semi-digital voltage control circuit
Inventor: ROELLGEN BERND
IPC: G05F1/46
Filed: 1986-02-05
Abstract: The previously exclusively fully analog voltage control circuits can be adjusted only inaccurately without a voltmeter. In addition, ergonomics and technical data require improvements. Digital methods are used for achieving a more accurate adjustment of the output voltage. This is provided by a 4-bit binary counter which is followed by a D/A converter and a potentiometer. The output voltage in each case increases by 1 V when the binary counter is incremented. 15 voltages (maximum deviation: 0.03 V) are available; intermediate values are set with the potentiometer. Because it is independent of the coarse adjustment, the fine adjustment becomes more accurate. The constant voltage which should be as stable as possible and is needed in the case of voltage control circuits is provided by a battery instead of the usual Z diodes. Since the battery is independent of input voltage fluctuations, it has ideal characteristics. The battery remains almost free of load by connecting to it a voltage follower. The output voltage of the voltage follower, which has a high load-carrying capability, is always identical with the battery voltage. In general, the use of voltage followers throughout contributes to an improvement of the technical data and the use of light-emitting displays contributes to improved ergonomics for reading the set output voltage. The circuit is suitable for installation in power supplies and for correcting the output voltage of power supplies.

Title: Tension-resistant clamping of a flat element into a mounting formed by two parallel abutment surfaces spaced apart
Inventor: KELLERMANN DIETER
IPC: F16B5/06
Filed: 1986-02-25
Abstract: The proposal is for a particularly simple means for the tension-resistant clamping of a flat element (21) into a mounting (112, 113) formed by two parallel, torsionally rigid abutment surfaces (112 and 113) spaced apart. This is achieved with the aid of clamping means which are supported, at one end, directly against one (112) of the surfaces (112 and 113) forming the mounting and, at the other end, against the other surface (113) forming the mounting via the flat element (21) to be clamped. The clamping means is formed by a dimensionally stable strip (16) which has two parallel longitudinal edges (161, 162), which has a width greater than the internal width of the mounting (112, 113), to which is added the thickness of the flat element (21) clamped, and, with one (161) of its longitudinal edges (161, 162) further forward in the direction of tension, is supported against one (112) of the surfaces (112, 113) forming the mounting and, with its other longitudinal edge (162) further towards the rear in the direction of tension, is supported indirectly on the other (113) of the surfaces (112, 113) forming the mounting via the flat element (21) to be clamped, which rests against this surface (113). <IMAGE>
