Patent DE-3132383-A1 (DE)
Title: Standard of length for checking the accuracy of measurement of coordinate measuring devices
Inventor: SCHUESSLER HANS-H DIPL-ING DR
IPC: G01B5/00
Filed: 1981-08-17
Abstract: The invention relates to a standard of length for checking the accuracy of measurement of coordinate measuring devices, in which there are provided two scannable balls which are held at a known separation (spacing, distance) from one another and have a precisely machined surface. The position of at least one of the two balls can be varied inside the measurement volume of the coordinate measuring device. In order to exclude temperature-induced changes in length such as occur with spherical end-measuring gauges (spherical gauge blocks), and in order to be able to use the standard of length universally and for comprehensive checking, the balls are held on a carrier such that the separation can be varied. The separation of the balls is monitored continuously interferometrically. For this purpose, the balls are hollow-bored at least partially along the course of the measurement beam of the interferometer arrangement and arranged to have the same axis relative to the measurement beam. The optically active parts of the interferometer arrangement - interferometer divider with active layer and triple reflector with a centrally symmetrical point - are arranged in the interior of the calibrated balls in such a way that their critical geometric location is at the centre of the ball. As a result, only the centre separation is determined irrespective of any possible swinging of the balls. So as to permit different positions of the balls inside the measurement volume and to avoid collisions with components of the coordinate measuring device, the carrier can itself be inherently capable of changing length as well as pivoting and inclining. <IMAGE>

Patent DE-3202789-A1 (DE)
Title: Digital/analog converter circuit
Inventor: MORIYAMA MASARU
IPC: H03M1/00
Filed: 1982-01-28
Abstract: A D/A converter circuit is described with two data selectors (DS1, DS2) and two D/A converters (DAC1, DAC2), each having an external reference input terminal (3, 4). A decoder (DC) receives several bit stages including the most significant bit (MSB) and converts these into an analog signal which indicates whether or not the digital signal present represents an analog signal quantity which is greater than a predefined fraction of the full-scale value of the analog signal, and in this way the expansion or non-expansion mode of the D/A converter circuit is controlled so that an m-bit-processing converter can be used as a first D/A converter in the processing of a signal containing n bits, where n > m. The first D/A converter receives information comprising m bits including the MSB in expansion mode and receives information comprising m bits including the least significant bit (LSB) in non-expansion mode. The second D/A converter receives information comprising K bits including the LSB from the present digital signal (K = n-m) in expansion mode and receives a pre-defined digital data signal from a permanent data circuit (SD) in non-expansion mode. The second D/A converter performs a D/A conversion using a fixed voltage, and the emitted analog voltage of the second converter is superimposed on the fixed voltage and then fed to the first D/A converter as a reference voltage as soon as expansion is required. <IMAGE>

Patent DE-3218379-A1 (DE)
Title: Vehicle seat with a rail guide which can be adjusted and locked in the direction of travel
Inventor: SEITEL HEINZ
IPC: B60N2/08
Filed: 1982-05-15
Abstract: The invention relates to a vehicle seat with a rail guide which can be adjusted and locked in the direction of travel, a trigger handle for the rail locking bolt and a shock absorber which is assigned to the rail guide and absorbs longitudinal impacts to the front and to the rear and can be switched on and off as desired in that the free passage of the shock absorber is obstructed by a locking bolt or released. Switching off occurs if excessively large horizontal impacts and deflections occur. The mechanisms for locking the rails and the switching on and off of the longitudinal shock absorber have previously been too costly, too complicated and too user-unfriendly. In accordance with the object upon which the invention is based, a remedy is provided for this in that the handle which serves to release the rail locking bolt and the switching handle for switching on and off the longitudinal shock absorber are combined to form a common actuation handle, and in that this handle is in a driving connection both with the rail bolt and the locking bolt which is assigned to the free passage for the shock absorber, the adjustment range of the common actuation handle extending over three defined switching positions, the 1st position of which being assigned to the rigid locking position of the rail guide when the free passage of the shock absorber is switched off, the 2nd position being assigned to the locking position when the free passage of the shock absorber is switched on and the 3rd position being assigned to the released lock of the rail guide. This results in a more simple arrangement and design of the rail lock and of the switching device for the longitudinal shock absorber, a reduced space for arranging these and a simplified synchronous controllability of these mechanisms.
