Patent DE-4309999-A1 (DE)
Title: Profiled pipe of crosslinked polyolefin for the renewal of pipelines
Inventor: IMGRAM FRIEDRICH
IPC: F16L55/165
Filed: 1993-03-27
Abstract: For the renewal of predetermined lengths of leaking or damaged pipelines, use is made of a pipe of thermoelastic crosslinked polyolefin which has been thermoelastically deformed at temperatures above the crystalline melting point in comparison with the pipeline to be renewed and with its original dimensions, to be precise (a) to a smaller diameter, and (b) increased wall thickness and (c) to form a profile of reduced cross-sectional area. After introduction into the pipeline to be renewed and heating to a temperature above the crystalline melting point, the profiled pipe tries to revert to its original shape and, as a result, comes into sealing contact with the pipeline to be renewed, without this being accompanied by any significant change in length.
Patent DE-4311337-A1 (DE)
Title: Transportable unitised unit

Patent DE-4312554-A1 (DE)
Title: Non-powered and keyless quick-locking clamping system for fastening parts to all machinable materials
Inventor: LEEB FELIX
IPC: B23B51/05
Filed: 1993-04-17
Abstract: An annular bore is produced with the use of a type of router in combination with a tool which is designed in a hollow form. Here, it is possible to produce such an annular bore in all machinable materials with appropriate tipping of the tool edges. A mounting ring, for example, can then be braced via this annular bore, which then results in automatic centrality of the recess to be produced if the annular recess is made accordingly. Since the bracing takes place with a hand-lever movement in combination with an eccentric, no power at all is required. Essential features are likely to lie in the fact that, apart from bracing in the recess, at the same time an axial pressure is achieved on the standing legs through the sloping arrangement of the clamping-jaw carriers in combination with a wedge-shaped bearing surface. In particular, no lever actions at all occur, since the expanding action is uniformly distributed over the intended recess (provided the annular bore is produced via the intended recess), in which case torsional forces in particular, which are certainly not inconsiderable during the drilling and milling, are absorbed in a torsionproof manner mainly via the standing legs. But the most important advantage is likely to be that only a quite small clamping surface is necessary.

Patent DE-4410872-A1 (DE)
Title: Shaping press
Inventor: HOEGGER CORNEL
IPC: A22C7/00
Filed: 1994-03-29
Abstract: The adjustment of the pressing pistons for shaping meat pieces takes place 2-dimensionally or 3-dimensionally, it being known that the rams have fixed heights. It is likewise known that, with such arrangements, either the meat structure can be damaged or the meat piece is undulated in the case of thicker or thinner meat pieces. For this reason, a pressing piston is modified in height either for the length or the width. The thickness ram (2) is in this case moved at a given pressure and the thickness or height of the meat piece is adjusted automatically. With the proposed self-adjusting ram (1) for the length or the width, the ram (1) which adjusts to the different thicknesses of the meat piece can end the respective difference in height of the individual pieces in the pressing mould in the case of differing thickness and the structure of the meat is not changed. <IMAGE>

Title: Magnetic-resonance (nuclear-spin) tomography instrument and method with noise attenuation
Inventor: YOSHINO HITOSHI
IPC: F16F15/00
Filed: 1994-09-14
Abstract: Amongst other things, a gradient magnetic field production device (109) for producing a gradient magnetic field in a space in which an object to be examined is to be arranged is described, which has at least one gradient magnetic field coil (190) and a retention part (191) for the coil, which is deformed by an electromagnetic force as is produced when a current is passed through the coil. Such a device conventionally produces noise and oscillations whenever a pulsed current is sent through the coil, since the said electromagnetic force then results and the coil, as well as the retention part for the latter, are deformed. According to the invention, a force for preventing this deformation is applied to the retention part. In the case of a preferred exemplary embodiment, a piezoelectric component (130) is fastened undamped to the retention part, and the force for preventing the deformation of the retention part is applied by controlling the voltage applied to the piezoelectric component. <IMAGE>
