Title: Method for the production of castings from metallic material with an embedded lining for cavities, ducts and hollows
Inventor: MAUS WOLFGANG
IPC: C23C4/06
Filed: 1987-02-24
Abstract: In this method, by means of which it is possible, for example, to produce internal combustion engine port liners with a smooth internal surface, the lining is first applied to a lost core by flame or plasma spraying, the individual layers of the lining having different porosities and a compostion that changes from the inside towards the outside, this being achieved by replacing an increasing proportion of the ceramic in the spray powder by metal to give a graduated structure. Layers of sprayed-on or wound fibres can furthermore be provided for the purpose of reinforcement. There is then no difficulty in joining the last sprayed-on layer, which consists of pure metal, to the components produced by casting around it. The graduated structure reduces the differential thermal expansion of the metal and the ceramic without giving rise to impermissibly high stresses. <IMAGE>

Title: Mechanical device for protecting cars against theft by blocking the gear lever and the handbrake lever
Inventor: SECKINGER HERMANN
IPC: B60R25/00
Filed: 1987-12-11
Abstract: The divisible articulation on the appliance shaft of the device for protecting cars against theft is intended to make it possible to remove the generally fixedly installed appliance in exceptional cases in a quick and uncomplicated manner, while at the same time retaining easy access to the said appliance. The design must, however, be such that it is impossible to remove the system in the operating position. This requirement is fulfilled, in that removal can only be achieved if the appliance is bent through about 30@. The bending and therefore the removal of the system is not possible in the operating position when the antitheft device is locked. The divisible articulation makes it possible to use the antitheft device even when there are complicated plastic coatings in the region of the gear lever.

Patent DE-3808599-A1 (DE)
Title: Torsional vibration damper, in particular for cutting machines
Inventor: SEEFELDT JOACHIM
IPC: F16D3/56
Filed: 1988-03-15
Abstract: In the case of a torsional vibration damper (1), commercially available pins located in a ring axially parallel to the axis of rotation (20) are arranged, as vibration-damping transmission elements (23), in such a way that they form, in addition to their longitudinal portions (25, 26) fixed in the associated rotary bodies (12, 13), intermediate longitudinal portions (27) which have freedom of movement in the direction of rotation and are resilient. As a result, any alternating torsional oscillation coming from a drive can be suppressed in an extremely simple manner and over a very large frequency range. To secure the transmission elements (23), subjected substantially exclusively to bending, against shearing off, a stop device (22) is additionally provided as overload safety device in the same ring. Furthermore, the two rotary bodies (12, 13) are mounted directly against one another in a manner free from play by means of prestressed rotary bearings (19). <IMAGE>

Title: Weaving machine with a weft-thread changing system
Inventor: FREI OSKAR DIPL ING
IPC: D03D47/38
Filed: 1988-08-19
Abstract: In a weaving machine, a weft-thread changer is controlled by a piston (4) of a pneumatic cylinder. The piston can be loaded on both sides by compressed air which is controlled in such a way that, in order to brake the piston before it reaches an end position, overpressure prevails in that part of the cylinder towards which the piston moves, in relation to the other part of the cylinder. The cylinder spaces (40a, 40c) in front of and behind the piston (41) can be closed off relative to the environment during the piston stroke, so that the drive force on the piston is generated purely as a result of the expansion of the compressed-air volume (40c) enclosed on one side of the piston and the braking force occurs on the other side as a result of the compression of the pressure volume (40a) enclosed there. A jolt-free movement of the weft-thread changer (32) as far as the end position is thereby possible. <IMAGE>
