Patent DE-3221835-A1 (DE)
Title: Intramedullary bipolar spreading and compression splint
Inventor: DIEM WOLF-JUERGEN
IPC: A61B17/72
Filed: 1982-06-09
Abstract: For the extension of the operative indications and improvement of the rotational, compressive and bending stability of defined fractures of the long tubular bones of the extremities the invention proposes a bone marrow splint which permits triple, reversible bracing followed by axial compression of the bone fragments in each of the upper and lower thirds of the drilled-open medullary cavity. Two bipolar, partially flexible, conical sliding bodies (2, 5) cause trigonally elastic expansion of the longitudinal spring steel jaws, which rest directly against the outside and can be clamped conically at an angle of 120 DEG  relative to one another, independently of one another during axial movement of two concentric screw bolts (1, 4) in opposite directions on the two peripheral spreading units (3, 6). These jaws exert at any one time an appropriate contact pressure on the surrounding bone wall layer, of different thickness of the upper and lower medullary cavities (Fig. 3), which contact pressure can be both metered and controlled using a graduated special socket spanner (Fig. 2). The entire mechanics of the axial movement systems is enclosed in a metal sleeve (8) on whose upper and lower ends three slots are in each case provided in a manner such that they guarantee a spreading and compression operation which is as frictionless and sealing as possible. <IMAGE>

Title: Device for the contactless crushing of concrements in the body of living beings
Inventor: EISENMENGER WOLFGANG PROF DR
IPC: A61B17/22
Filed: 1983-04-02
Abstract: There is described a device for the contactless crushing of concrements in the body of living beings, especially for crushing renal calculi with the aid of shock waves focussed on the concrement. A metallic diaphragm adjoining a transfer medium which exerts a counter-force is provided for generation of the shock waves. The metallic diaphragm is separated from a flat, spiral conductor arrangement, which is attached to the front side of a carrier and can be exposed to an electrical pulse of specific intensity and time duration, by a thin insulating layer. By this embodiment, the shock waves are generated electromagnetically. It is therefore no longer dependent on a liquid as the transfer medium. In addition, the intensity and duration of the shock waves generated can be changed independently in a simple manner.

Title: Process for a safety system for reducing the risk of accident due to excess speeds in motor vehicles and motor cycles
Inventor: OVERSOHL WILHELM DIPL CHEM DR
IPC: B60K31/04
Filed: 1983-08-18
Abstract: The process consists of predetermining speed ranges in motor vehicles by way of governors, with different maximum speeds such as 50kph for urban traffic, 100kph for trunk roads and unlimited speeds for motorways and by way of the governor preventing the maximum speed for the respective speed range from being exceeded and displaying the speed range selected by the driver by means of a conspicuous sign perceptible from the outside to all road users. Such a sign might take the form of different coloured lights which might be combined with the number plate illumination or a coloured light on the vehicle roof. The process is safeguarded by way of a suitably encapsulated governor against tampering, switching off or bypassing of the computer-controlled process sequences. The process does not involve any interference in the technical performance or development of motor vehicles but prevents the dangerous exceeding of permissible maximum speeds, in particular by the fact that driving in unadmissible speed ranges is visible and thereby easily monitorable. As a result an effective inhibition from exceeding the speed limit is instilled in the driver. Technical implementation of the process is compatible with the capabilities of the relevant control engineering, for example by way of mini computers. The process is applicable to all ...

Patent DE-3343553-A1 (DE)
Title: Cooking and heating vessel
Inventor: SCHALLENBERG KARL-HEINZ
IPC: A47J27/00
Filed: 1983-12-01
Abstract: The vessel according to the invention has a dual-walled jacket and a dual-walled lid. Their interiors are connected to the atmosphere via pressure-relief valves. When the vessel is placed on a hotplate, not only is the product situated therein heated but also the air contained in the jacket and the lid interior. The air expands with an increase in pressure. The pressure is released into the atmosphere via the pressure-relief valves. As a result, the number of air molecules present in the interiors is reduced. The air which now becomes thinner is a poor heat conductor. As a result, a space of thinner air is produced which forms a thermal insulation. This means that the vessel radiates no heat or only very little heat into the surroundings via its jacket and its lid. As a result, this leads to an energy saving of up to 80% during cooking or heating up food.

Title: Compressible flat packing material
Inventor: ZERFASS HANS-RAINER DR
IPC: F16J15/10
Filed: 1984-08-17
Abstract: A compressible flat packing material, in particular for producing flat gaskets of internal-combustion engines, such as oil-sump seals, cooling-water pump flange seals or valve-bonnet seals, preferably comprising a fibre nonwoven of mineral fibres, natural fibres and/or synthetic fibres, without incorporated steel sheet, with a binder and a powdery to fine-grained filler, contains as filler a magnetisable material in quantities of preferably between 5 and 50 per cent by weight of preferably bariumferrite and/or ferrite, which if appropriate is magnetised in the fibre nonwoven. The fibre nonwoven material can thus be fixed using magnetic forces, lying flat on underlying surfaces, so that in particular a porous bearing under pressure of sealing overlays is possible. Similarly, the seals produced can be fixed with good adhesive strength as an assembly aid at sealing points where access is difficult, such as for example some flange faces on seals.
