Inventor: HEIDELBERG GOETZ
Filed: 1988-05-02
Abstract: In an electromotive actuator having a plurality of groups of in each case n coils S1 - Sn, to which in each case one invertor U1 - Un is allocated, in order to be able to form both individual load circuits and group load circuits of different size, group switches 12, 23, 34 ... (n - 1)n are located between the coils S1 - Sn, while isolating switches 11, 11', 22, 22' ... are located between the invertors U1 - Un and the coils S1 - Sn. The individual invertors are each divided into two half bridges 131, 132; 231, 232 .. on the basis of the said switches. If a plurality of coils are connected in series, they form, for example, coil pairs S1, S2; S3, S4 ..., the half-bridge pair which is located on the input side or output side of the coil series circuit being used to drive the coil series circuit. <IMAGE>

Title: Method for monitoring the thickness of brake linings of a disc brake
Inventor: HORVATH HELMUTH ING
IPC: F16D66/02
Filed: 1988-05-18
Abstract: In order to be able to check the wear of the brake linings with an electrical signal even in the case of a potential-free brake disc (BS), inductive sensors in the form of displacement sensors (WA) are mounted on the brake caliper (BZ) of the disc brake. They emit a measurement signal proportional to the wear at least towards the end of the useful life of the brake linings. When this test interval is reached, the expected life of the brake linings in kilometres is calculated from the kilometres travelled. This extrapolation is repeated at regular intervals. If two displacement sensors (WA) are used for each jaw of the brake caliper (BZ), uneven wear of the brake linings can be detected by comparison of the measurement signals. The use of the method according to the invention is particularly advantageous on rail vehicles and heavy vehicles. <IMAGE>

IPC: G01V15/00
Filed: 1988-08-24
Abstract: An interrogator creates a magnetic field at a selected frequency in a monitor zone. It includes a receiver establishing disturbances in the field of the zone to give out a characteristic signal. The receiver has a channel for giving out a signal content characteristic for the energy levels in one resp. band of a number of bands of the signal. An evaluator responds to the signal contents to compare the energy levels which are characterised by the signal content, with the object of evaluating whether there is an article present in the zone. There are pref. at least three bands, and the first signal content for a resp. band of the number of bands, has signal levels which are characteristic for the energy in that band. The evaluator, in the course of evaluation compares these levels.

Patent DE-3910028-A1 (DE)
Title: Method and device for controlling the mass flow of a conveyed material
Inventor: KALATA PAUL R
IPC: G05B13/02
Filed: 1989-03-28
Abstract: A device for controlling the mass flow of a conveyed material uses a stochastic control process. The weight of the conveyed material is detected and a statement about the mass flow of the material is made with the aid of a Kalman filter process. Plant disturbance processes and measurement disturbance processes which influence the measured weight are modelled as stochastic processes and are used together with the detected weight for estimating the mass flow. The disturbance model is also able to detect severe disturbances. With the aid of the estimated mass flow, by comparing with a desired value, a manipulated variable is calculated for a conveyor motor. In this way, in spite of unavoidable disturbances, the mass flow is controlled to a desired value with minimal error variance. A self-adjusting process is used in order to determine parameters for plant disturbance processes and measuring disturbance processes exactly. By means of the good determination of the parameters, a good response behaviour results, whilst maintaining the desired value with only small fluctuations.
