Title: Method and circuit arrangement for determining the degree of filling of a reel
Inventor: KEGLER ERNST
IPC: G11B15/54
Filed: 1982-08-10
Abstract: For determining the degree of filling of a reel (S1), in particular a reel on which a magnetic tape (MB) is wound up, the number of revolutions of the reel (S1) during a period of time and the number of revolutions during this period of time of a roller (R1) in effective connection with the magnetic tape (MB) are measured. Subsequently, the quotient of the number of revolutions of the roller (R1) and the number of revolutions of the reel (S1) is determined, which represents a measure of the degree of filling. By using a read-only memory (FS), the required torque and the motor current of a drive motor driving the reel (S1) are determined from the quotient. <IMAGE>

Title: Method for automatic testing of a system section of a computer-controlled system, particularly for testing the multi-stage speech path switching network of a telephone switching system
Inventor: LINDEINER HANS-DIETRICH VON DI
IPC: H04Q1/24
Filed: 1982-09-28
Abstract: For testing functional sections representing, in particular, switching matrices of a multi-stage speech path switching network (KN) with the aid of computer-controlled test equipment (PE), it is provided that after a first error has been found in the respective functional section, the latter is immediately left and the next functional section provided in the test sequence is changed over to. In each case, a first error is simulated by the fact that the evaluating possibility (S2) for the test criteria is suppressed. The connection (S1) necessary for the data exchange between the test equipment and the system is effectively connected through. During this testing of the speech path switching network, errors with a wide range of effects which relate to the speech paths, the control and program level, can be detected with a short testing time.

Patent DE-3247001-A1 (DE)
Inventor: ROTZLER FRANK
IPC: B21F23/00
Filed: 1982-12-18
Abstract: This invention relates to a gripping feeder for an intermittent feeding of strip or wire stock in presses, stamping machines or similar machines. It is an object of the invention to provide such gripping feeder which permits a change of the stroke length to be effected from the outside while the machine is in operation and permits such change to be effected manually or by means of an adjusting motor and also permits an automatic adaptation of the feeding and retaining grippers to the thickness of the strip or wire stock to be fed. This is accomplished in that the carriage carrying the feeding gripper is adapted to be driven from the main drive of the machine via a feed rocker, which extends transversely to the direction of travel of the carriage and is fulcrumed on a slider, which is slidable along a rail that extends transversely to the direction of travel of the carriage so that an adjustment of the slider along said rail will result in a change of the stroke length of the carriage. The feed rocker fulcrumed on the slider is preferably adapted to have an oscillating angular motion about its fulcrum imparted to it by a pivoted finger, to which an angular oscillation is imparted from the main drive, and which is pivoted to one arm of the feed rocker, the other arm of which is connected to the carriage by a link for imparting a reciprocating linear movement to the carriage.

Patent DE-3318874-A1 (DE)
Title: Stimulating current device for treating atonically paralysed musculature
Inventor: EICHHORN KARL DR
IPC: A61N1/36
Filed: 1983-05-25
Abstract: Stimulating current device for treating atonically paralysed, i.e. enervated musculature, having outputs which are preferably multichannel and perfectly isolated from one another electrically, each of these outputs generating bidirectional stimulating-current curves suitable for stimulating atonic paralyses and temporally coordinated correspondingly with one another. The stimulating-current curves are fed to the patient via electrodes. They are produced by firstly producing a medium-frequency oscillation (square pulse sequence), which is not suitable for treating atonic paralyses and is connected, possibly after amplification, to the primary side of only one transformer, which contains a number of secondary sides which corresponds to the number of the channels, controlled rectifier circuits or polarity-reversal circuits being connected downstream of said secondary sides in each case. The polarity reversal circuits, which are preferably formed from thyristor bridges, are fed signal pulse shapes corresponding to the effective stimulating-current curve shapes to be built up on the secondary sides. Furthermore, it is possible to suppress the pain due to the current by directly feeding the medium-frequency signal generated.
