Title: Tool for machining the surfaces of cast iron which contains carbon and has been subjected beforehand to electrochemical surface erosion
Inventor: HECK KLAUS DIPL ING
IPC: B24B33/08
Filed: 1981-12-11
Abstract: The invention relates to a tool for machining surfaces of cast iron which contains carbon and has been subjected beforehand to electrochemical surface erosion, in particular for machining the cylinder bores of internal combustion engines, with at least one strip which can be pressed with a friction surface against the surface to be machined and can be moved relative to this surface. To obtain tribulogically improved surfaces, the strip is designed as a friction-cladding strip, the friction surface of which is provided with sharp-edged grooves (38) and/or pores (36) at an angle to the direction of movement. To machine cylindrical bores, the friction-cladding strips can be fastened to strip carriers which are guided in a radially adjustable manner via several guide bolts in corresponding bores of a tool head, in which arrangement the guide bolts can be acted upon by hydraulic fluid under pressure. The hydraulic fluid can at the same time serve as flushing fluid through the provision of appropriate passages.

Title: Composite component
Inventor: QUANTE HEINRICH
IPC: E02D5/00
Filed: 1982-06-09
Abstract: A composite component which absorbs tensile and compressive forces and can be used for a wide variety of purposes comprises an alpha-hemihydrate core, which is enveloped on all sides by the reinforcement comprising flat metal sheets and designed as a shell. The alpha hemihydrate has compressive strengths of 120 N/mm<2> and is consequently suitable for absorbing correspondingly high forces, whereas tensile forces occurring are absorbed by the enveloping reinforcement. The hollow body of the metal sheets is expediently joined together during the curing operation to form a closed profile, so that the curing of the core is not hindered. A corresponding composite component can be used above ground and under ground as a beam, composite beam, frame corner or similar component. Fig. 3 is intended for publication. <IMAGE>

Title: Magnetic train-influencing device
Inventor: SCHWARZBACH WALTER
IPC: B61L3/12
Filed: 1983-05-06
Abstract: A magnetic train-influencing device consists of a track magnet arranged on a section of track, the force flux of which magnet is received by the pole shoes of a vehicle magnet when a rail vehicle passes. The vehicle magnet (FT) has a polarised relay (PR) whose switching-over contact (UT) changes from a first switching position into the second stable switching position when subjected to magnetic influence. In this process a previously switched-on travel-inhibit relay (FS) is switched off. In the vehicle magnet (FT), an auxiliary winding (HG) which can be switched on by a control operation is also provided, with the aid of which winding (HG) the polarised relay (PR) can be switched back into the first switching position. In order to increase the operational safety, it is essential that in each case a supplementary relay (ZS1, ZS2) which can be switched on in each of the two switching positions of the polarised relay (PR) and whose working and idle contacts form an anti-valence test circuit is provided. During correct operation, a test relay (P), one working contact (P1) of which is located in the switching-on circuit of the auxiliary winding (HG) is switched on by the anti-valence test circuit. Further contacts (ZS11, ZS21) of the supplementary relays (ZS1, ZS2) which are connected in series are located in the switching-on circuit of the travel-inhibit relay (FS). <IMAGE>

Patent DE-3333830-A1 (DE)
Inventor: HINKEL RALF
IPC: G01C3/00
Filed: 1983-09-20
Abstract: The distance measurement is accomplished by measurement of a blur disk (4) produced on the object by a laser point (1) viewed through a ''blur''-adjusted objective (2). If, in doing so, the image is measured on a reception plane (3) outside the image distance b, then the diameter D of the blur disk (4) being produced is inversely proportional to the light point distances and it can be determined by means of a light-sensitive line receiver according to the number of the reacting reception cells. The accuracy of the measurement is only influenced by the dimensioning of the optics being used and by the resolution of the line receiver, the measurement time being essentially dependent only on the reaction time of the reception cells.
