Title: Computer tomograph
Inventor: LIEBETRUTH REINER DIPL ING
IPC: A61B6/06
Filed: 1993-02-09
Abstract: A computer tomograph is to be provided in which image artefacts are to be avoided when passing radiation through objects with a highly elliptical cross-section. The primary radiation shutter (6) is controlled during the rotation of the X-ray bundle (7) in such a way that its density is increased in a prescribed angular range in which a particularly large degree of weakening of the radiation occurs.

Patent DE-4305891-A1 (DE)
Title: Seal for parts moving in a translatory manner
Inventor: KECK MATTHIAS
IPC: F16J15/324
Filed: 1993-02-26
Abstract: The invention relates to a seal for sealing off from a medium parts which move in a translatory reciprocating manner. The seal consists of an annular basic body which is roughly rectangular in cross-section and has a sealing zone in the area of the end face facing the medium. The radial cross-section of the sealing zone is greater than an installation space accommodating the seal. In the installed state, the sealing edge of the sealing zone bears under prestress against the dynamic sealing face of the moving part, in which arrangement a supporting zone facing the dynamic sealing face and consisting of a row of bearing bodies lying at a distance from one another in the peripheral direction is formed in the area between the sealing edge and the end face facing the medium. In order to obtain sound sealing at a low leakage volume, provision is made to form the boundary edges, remote from the medium, of the bearing bodies essentially at an angle to the translatory direction of movement of the moving part, the boundary edges, opposite one another, of adjacent bearing bodies defining a return funnel for the medium. The return funnel narrows in the direction of a passage formed by the gap.

Title: Device for the electrolytic inactivation of sperm for use in men
Inventor: KOSSACK CHRISTIAN
IPC: A61F6/20
Filed: 1993-04-13
Abstract: The present invention concerns a device for the electrolytic inactivation of sperm for the purpose of contraception for use in men </H0> Said device is applied in the vas deferens (seminal duct) located in the scrotum and prevents the fertilising ability of the sperm by electrolytic decomposition. The electrical energy required for the purpose is produced by a voltaic cell which utilises the spermatic fluid as electrolyte. Electrolytic decomposition and the fertilising ability can be switched on and off, as desired, via a switching element from the outside without the need for any further surgical intervention. The invention avoids the shortcomings of earlier developments which manifest themselves, in particular, by damming up of spermatic fluid and its consequences (sterility due to adhesion blockage of the convuluted seminiferous tubules or formation of antibodies).

Title: Monitoring and protection device for optical-fibre cables (fibre-optic cables)
Inventor: ONKELS ECKEHARD DIPL PHYS
IPC: G02B6/42
Filed: 1993-04-29
Abstract: The subject-matter of the invention is a monitoring and protection device for optical-fibre cables which detects energy leakage from an optical-fibre cable or from an optical fibre as a result of an interference. Damage to the optical-fibre cable occurs by uncontrolled coupling-out (detection) of the laser beams at interference points of the optical fibres, for example due to the bending radius dropping slightly below the permissible value. In the device according to the invention, the optical-fibre cable is designed in such a manner that it has one or more optical fibres with in each case one or more fibre coatings (layers), in the case of which device at least one fibre coating is provided for transmitting radiation power (radiant power), and that the lost radiation leaking from the fibre coating or coatings transmitting the radiation power is coupled into a second fibre coating by means of elastic or inelastic diffusion (conversion) and is guided to a detector. The conversion of the lost radiation is in this case performed by a suitable preparation of the secondary coatings, for example by enriching it with diffusers, dyes or scintillators. In the simplest case the optical-fibre cable is surrounded by a protective sheath which is filled with a liquid or a gel-like dye or scintillator carrier. The device according to the invention has the advantage that an interference of the optical-fibre cable is recognised at an early stage, so that severe damage or total destruction of the optical waveguides by power reduction or switching off of ...

Title: Locking adjustment for vehicle seat
Inventor: KLIESE ANJA
IPC: A47C1/026
Filed: 1994-01-22
Abstract: The seat hinge has a shaped toothed segment (2) with the teeth concentric to a pivot point (10) of the locking segment (1). The respective contact points between the flanges of the teeth are on curves of different radii and provide a self locking effect in either direction. The two segments are brought into mesh, or released via release mechanism. The shapes of the interlocking teeth and the grip contacts on both sides of the tooth profiles provides a self locking effect which is increased by the elasticity of the gear segment material. The shaping of the tops of the teeth and the bottom sections of the slots between the teeth eases the meshing and eliminates torque peaks.
