Title: Apparatus for reading monitoring of a first and a second optical record carriers in the first and second modes of operation
Inventor: JONGENELIS ADRIANUS PETRUS JOH
IPC: G11B7/08
Filed: 1992-07-29
Abstract: A device in which a radiation source generates a radiation beam of a first wavelength. The scanning spot 7 generated by this radiation beam follows the centerline 13 of a track 8 to be scanned on a first type of record carrier designed for this wavelength. When a second type of record carrier is being read, in which the information is stored in a phase structure designed for a wavelength which is longer than the first wavelength, the read spot 7 follows the edge of a track 38 to be read instead of the centerline 18. In this way it is possible to generate a satisfactory information signal not only from the first type of record carrier but also from the second type of record carrier.

Title: Device for adjusting a cutting horizon of a coal-getting machine, particularly of a coal-getting plough
Inventor: RASSMANN CHRISTOPH
IPC: E21C27/34
Filed: 1992-12-18
Abstract: A mineral mining installation has a plough guided for movement along a scraper-chain conveyor. Roof supports are connected to the conveyor with the aid of shifting mechanisms which employ boom-type guide linkages designed to co-operate with a compact controller to adjust the tilt of the conveyor and the cutting horizon of the plough. The controller employs a plate-like guide block guided for up and down motion at the goaf side of the conveyor. An hydraulic piston and cylinder unit is disposed alongside the goal side of the conveyor and pivots a cranked lever to raise or lower the guide block. The guide block is coupled to a headpiece of an associated one of the boom linkages so that the motion of the guide block is transferred to the headpiece.

Title: Method of laser drilling for producing textile material and apparatus for making a foil
Inventor: JAMES WILLIAM A
IPC: B29C59/16
Filed: 1996-02-22
Abstract: Support members and method of forming support members for use in producing nonwoven fabrics, especially tricot-like nonwoven fabrics, and films. A topographical support member includes a body having a top surface comprising a pattern of a plurality of peaks and valleys and a plurality of apertures. The apertures have a conical top portion that is surrounded by a cluster of the peaks and valleys. The center line to center line spacing of adjacent apertures is less than the major diameter of the conical top portion of the apertures. The topographical support member is formed in a defocused process by focusing a laser beam so that the focal point is below the top surface of a starting workpiece and drilling with the laser beam the predetermined pattern of tapered apertures. The pattern of tapered apertures forms the cluster of peaks and valleys surrounding each aperture on the top surface of the resulting support member. A smooth, flat surface support member is formed by focusing the laser beam at the top surface of the workpiece or by adjusting the center line to center line spacing of apertures formed by the defocused process so that no peaks or valleys result. A perforated film or nonwoven fabric can be formed using the smooth surface support member.

Patent CZ-9602002-A3 (CZ)
Title: Method of setting micro-steps of a stepping motor
Inventor: RAUCH HANS
IPC: G01R7/06
Filed: 1994-05-28
Abstract: A process is disclosed for correcting a non-linear relation between the electric phase angle and the mechanical output angle of step motors by using a low resolution encoder or the like. This process represents a compromise between the classical regulation of step motors, that requires a high resolution angle detection, and a purely statistical correction of the characteristic curve. The result is a substantial synchronism improvement, for example when conventional claw pole step motors are used for driving the pointer of a display in a motor vehicle. The micro-step control is carried out with a corrected sine wave form. Coefficients evaluated by simplified Fourier synthesis are essentially used to correct the sine wave form.
