Title: Apparatus for WC flushing
Inventor: MANDL PETER DIPL ING
IPC: E03D1/14
Filed: 1983-11-04
Abstract: The apparatus and control device according to the invention for WC flushing allow, above all, a considerable saving of water in addition to improved convenience, whilst at the same time ensuring or increasing the cleaning effect. The advantages listed are achieved by a total of 3 different stages of the quantity of flushing water which may selectively also be metered automatically. In this case, the pre-flushing, measured to be about one 1/4  litre, brings about the desired bowl soaking which increases the effect of the following flushing. The main flushing then takes place with the full quantity of water or a quantity reduced to about 30% to 50%, as required (faeces or urine flushing). The alternative control for this purpose can be effected both by means of separate keys by hand and automatically by means of mechanical switches or electronic sensor devices. The long-term saving of water which can be achieved is in the order of magnitude of 35% to 50%.

Patent DE-3416122-A1 (DE)
Inventor: WEIK GUENTER
IPC: H01H11/04
Filed: 1984-04-30
Abstract: Contact materials having a contact layer of silver or a silver alloy, or a palladium alloy, have very good electrical properties. A disadvantage, however, is that a corrosion layer which forms even after a short time and which markedly increases the transfer resistance of the contact makes itself noticeable. In order to avoid this corrosion layer in an economical way, the invention provides that the contact face is gold-plated by electroplating, cathodic sputtering or chemical vapour coating and the contact material is then exposed for a short time to a temperature between 350 DEG C and 650 DEG C so that the gold can diffuse into the contact layer.

Title: Pressure-relief valve arrangement for the cooling circuit of a liquid-cooled internal combustion engine
Inventor: WEHRBERGER KURT
IPC: F01P11/02
Filed: 1984-06-19
Abstract: The invention proposes a pressure-relief valve arrangement for the cooling circuit of a liquid-cooled internal combustion engine for limiting the pressure during operation of the internal combustion engine and for limiting a comparatively higher pressure after the internal combustion engine has been switched off. This arrangement has a multi-stage pressure-relief valve which, in one stage, opens to the environment at operating pressure and, in a subsequent stage, opens to the environment at the comparatively higher pressure, in each case automatically. This multi-stage pressure-relief valve is integrated directly into a screw-on sealing cover and can be screwed on and off as part of the latter. It simultaneously contains a vacuum relief valve for automatically compensating the vacuum when the coolant cools down. The valve is simple, has only small dimensions and, in a single element that can be screwed directly onto the filler neck of the expansion tank, combines, on the one hand, a pressure-relief valve for limiting the operating pressure and, on the other hand, a pressure-relief valve for limiting the maximum pressure, in order to prevent damage in the cooling system and loss of coolant.

Patent DE-3427974-A1 (DE)
Title: Stabilisation of sand washed forward and sand washed up in coastal and island regions
Inventor: KUHLEMANN PETER
IPC: E02B3/04
Filed: 1984-05-25
Abstract: In order to keep and secure, i.e. "stabilise", amounts of sand that have been washed forward and washed up in particularly sandy coastal areas and islands, a method is proposed which incorporates the advantages of the so-called "petrifaction" (attended by its much-discussed disadvantages), but prevents its disadvantages. It is known that the sand washed forward in quantities of millions of cbm at coastal level and likewise in quantities of many millions of Deutschmarks in front of the dunes (e.g. Sylt) is washed back once again into the sea during storm tides and the like. It is therefore aimed to "stabilise" the same. Breakwaters, tetrapods or the protection of dunes by boulders are all unsuitable for this purpose and are more or less static, fixed and untransportable. By contrast, the proposed method of holding the sand by means of commercially available concrete rings is exceptionally cost-effective, versatile and also can be employed or modified in a pinpointed fashion, since it is transportable. The concrete rings can be laid vertically - in the shape of a pyramid (resembling dunes), or else horizontally - in honeycomb fashion over areas - and in multiple layers one above another. It is easily - in addition - possible to fasten them together as also in the subsoil. The sand is filled into these rings, so that the latter also disappear optically in and under the sand, and can even be planted (beach grass). In the case of multilayer application, the rings are stacked "offset", so that there is a natural resemblance to dunes, for example, (staircase shape). The ... Original abstract incomplete.

Title: Eddy-current clutch
Inventor: BOEHM HEINZ-DIETER DR ING
IPC: F01P7/08
Filed: 1984-11-29
Abstract: An eddy-current clutch is described which is provided with pole bodies which are arranged in a homopolar manner and lie with their ends at least partially axially in front of one another. A coil is allocated to the pole bodies. One of the two pole bodies is used as an armature ring, said pole body being arranged such that it can be displaced axially with respect to the other pole body and it being possible to place said pole body with its end surface forming a frictional lock on the end surface which faces it of the other pole body. The axially displaceable pole body is attracted against the force of a spring by a magnetic force which is produced by the coil and is matched to the spring force such that the clutch acts as a friction clutch above a specific switching point, but as an eddy-current clutch below this point. This switching point is selected such that the clutch acts as a controllable eddy-current clutch over virtually the entire range of operation, in that the maximum fan rotation speed is virtually never required. The clutch acts as a friction clutch only in the event of an increased cooling-air requirement. It is particularly suitable for fan drives for motor-vehicle engines.

Title: Type body for typewriters or similar machines
Inventor: THEILEN ROLF
IPC: B41J1/16
Filed: 1985-05-24
Abstract: The subject-matter of the invention is a type body for typewriters or similar machines having characters which are arranged in a matrix and can be adjusted by moving the matrix in the X and Y directions relative to a platen and constitute only a small mass. The type bodies are moulded onto spring-mounted fingers of a strip and each bear a plurality of characters which are combined to form groups. According to another exemplary embodiment, the type heads of the one group are moulded onto one strip and the type heads of the other group are moulded onto another strip, the spring-mounted fingers each having the same length. This thus results in identical bending lines during the impression between the two groups of type heads.
