Patent DE-3025837-A1 (DE)
Inventor: CHABORSKI HOIKO DIPL ING
IPC: G01M3/00
Filed: 1980-07-08
Abstract: A measuring cable with spaced measuring stations is laid. The measuring stations each have a sensor whose electrical conductivity depends on an ambient variable such as temperatures light etc., each sensor is provided with a control arrangement which, due to a transmitted signal from a control center, connects its sensor to a constant current source and returns a signal indicative of any voltage change dependent on the variable ambient which signal is measured by the control center. The measuring cable is divided into sections each having a selectable circuit which can be selected individually by the control center. A clock pulse signal is transmitted to all measuring stations but is only active for the cable section which has been selected. In this manner, the cable section can be chosen as desired, the time required for the control center to have access to certain measuring stations is shortened and semiconductor switches can be used because measurements are only made in the steady state.

Title: Supporting element for supporting workpieces
Inventor: HALDER WERNER
IPC: B23Q3/10
Filed: 1981-03-05
Abstract: A supporting body (2), which is supported in a supporting housing (1) such that it can be pivoted in on all sides around a pivoting centre (12), has in its part which projects beyond the supporting housing a supporting base surface (14) from which three supporting studs (15) project into a supporting surface (19) which is parallel to the supporting base surface (14) and is defined by the end surfaces (18) of the supporting studs. These supporting studs may be of cylindrical or truncated-conical (frustrum) shape. Their end surfaces are flat as a rule, but can also be slightly domed in a spherical shape. A rotationally symmetrical supporting surface, preferably a spherical-section surface (11), is used to support the supporting body (2). In order to limit the pivoting angle of the supporting body, a surface which deviates from the spherical surface, for example a flat (21), is integrally formed on the supporting body opposing the supporting base surface (14), in the pivoting path of which surface a stop surface is located which is formed, for example, by the hemispherical end surface (8) of a stop pin (3). The supporting studs (15) can be fitted at a uniform angular separation on a circular segment (16) around a centre axis (17) which leads from the pivoting centre (13) at right angles to the supporting plane (19). The alignment on three individual surface elements results in greater alignment accuracy with less clamping of the workpiece. <IMAGE>

Patent DE-3142664-A1 (DE)
Title: Device for generating images by means of electronically driven liquid-crystal arrays
Inventor: OTTEN ANDREAS
IPC: G03B21/00
Filed: 1981-10-28
Abstract: The invention relates to a device for generating images by means of electronically driven liquid-crystal arrays. Liquid-crystal array points are caused to respond by means of control voltages that are to be applied. The control voltage has to be very high in the case of long conducting paths to the array point that is to respond. A high voltage has the disadvantage in this regard that along the conducting path to the array point that is to be driven, other array points along this conductor track are caused to respond as well. In order to prevent this so-called cross-talk, liquid-crystal arrays have relatively small dimensions, in order to enable short conducting paths for which the application of low voltages is possible without cross-talk. The result is that large-format images cannot be generated. Consequently, according to the invention it is provided for the purpose of generating a large-format image by means of an electronically driven liquid-crystal array that a liquid-crystal array is inserted in the imaging plane of a projecting optical system, known per se, of a projector. This produces the advantage that a small-format liquid-crystal array can be driven with low voltages that prevent cross-talk, because an enlarging projection takes place as in the case of a conventional projector.

Patent DE-3204995-A1 (DE)
Inventor: MARTINI HELMUT DIPL ING
IPC: B23K20/08
Filed: 1982-02-12
Abstract: To separate combustion within a combustion chamber for deburring or high-temperature, high-pressure article treatment from gas supply valves, the combustion chamber is formed of a dual wall structure, having an outer wall (21) which is telescopically slidable with respect to an inner wall (12). The articles are introduced into the chamber (11) by placing a support plate (14) against the outer wall structure, with the inner wall (12) slightly raised, leaving a gap (23) between the lower edge of the inner wall and the support plate. Gas introduced within the outer wall structure than can pass into the chamber (11) within the inner wall, through said gap. When the requisite volume and pressure of fill gas-typically oxygen and a combustion gas such as hydrogen, methane or the like-is within the chamber, the inner wall (12) is lowered into sealing engagement with the support plate (14), for ignition of the combustible mixture. The inner wall, thus, totally isolates supply ducts and valves from being affected by the explosive pressure.
