Title: Device for measuring and machining workpieces
Inventor: KRIEG WERNER
IPC: G01B11/00
Filed: 1987-06-27
Abstract: The device for measuring and machining workpieces for coordinate measuring instruments and machine tools comprises optical deflecting elements which are arranged on an X, Y, and Z carriage and which are assigned beam-position sensitive photoelectric receivers (detectors). By means of these deflecting elements, a Cartesian coordinate system which is independent of the coordinates which are formed by the guides of the carriages is constructed by optical pilot beams which are emitted by a laser. Control devices which are controlled by the signals of the receivers via a computer, for a base and intermediate base carrying the deflecting elements, make it possible to determine precisely the position, for example of a measurement head or a tool, in the work space of the machine in six degrees of freedom.

Title: Method for locating noises from leaks, and device for carrying out the method
Inventor: IANN HERBERT DR
IPC: G01M3/24
Filed: 1987-08-10
Abstract: The invention relates to a system for locating leaks, which senses the emission noises from a leak in a pipe either directly from the line or at the surface of the ground, and amplifies, filters and digitises them. The digitised noise from the leak is subjected to spectral analysis, and the leak spectrum thereby obtained is compared in terms of the distribution of frequency and intensity with reference spectra of known tube leaks which are stored in the unit. The unit can indicate as the result of the comparison the type of leak which has the greatest similarity to the actual noise from the leak, and can establish whether the spectral components of a leak are contained in a current noise from a leak disturbed by environmental noise.

Title: Method and device for lapping bevel gears
Inventor: BUMM KARLHEINZ
IPC: B23F19/02
Filed: 1987-09-09
Abstract: A method of lapping bevel gears is proposed, based on the known fundamental principle of lapping, according to which only stock is removed where two surfaces move relative to one another under pressure. In the lapping principle used up to now, the tooth flanks distorted to a varying extent during hardening are acted upon uniformly by the peripheral force. The stock removal is uniform. The proposed lapping method is intended to lap the tooth flanks affected by hardness distortion with increased pressure and thus permit partial stock removal. <IMAGE>

Title: Optically integrated polarisation junction for monomode transmission systems and its use
Inventor: NEYER ANDREAS DR
IPC: G02F1/313
Filed: 1988-01-19
Abstract: In order to split the light of any desired polarisation which is guided in a monomode strip waveguide into its two orthogonal linearly polarised components and to guide these off in monomode strip waveguides, an optically integrated polarisation junction is specified. As shown in Figure 1, it consists of two monomode input and output waveguides which are combined to form a twin-mode strip waveguide. As a result of birefringent effects the twin-mode interference in twin-mode waveguides is influenced in a different way for the two polarisation directions so that a splitting up of the polarisation components can be achieved. Also after the production of the waveguide structure the splitting ratio of the polarisation components can be altered with the aid of numerous devices. The optically monomode polarisation junction can be used, for example, as a passive or electrically tunable polarisation-selective branching point or else as a polarisation-independent switch. <IMAGE>

Title: Method for the production of monolithic metallic blanks by controlled solidification
Inventor: MOVCAN BORIS ALEKSEEVIC
IPC: B22D11/00
Filed: 1988-11-04
Abstract: The method for the production of monolithic metallic workpieces by controlled solidification consists in that a liquid metal melt 4 is produced and the surface of the melt 4 is heated to give a temperature change pattern. The temperature change pattern of the melt 4 is determined by a temperature gradient between heating zones and cooling zones. The lines of equal temperature form isotherms 11, 12. The heating zones 9 are ordered in such a way that the isotherms 12 representing a temperature approaching the crystallisation temperature Tk reproduce the cross-sectional shape of the blank to be produced. An innoculator 8 is inserted equidistantly from the isotherm 12 at the crystallisation temperature Tk. By subsequently withdrawing the innoculator 8 from the melt 4 at a linear speed which is determined by the crystallisation rate, the formation of the blank is brought about. The invention can be employed in the construction of tools and equipment, in the energy industry and in other branches of industry. <IMAGE>
