Title: Railway safety equipment monitoring position of end of train end by detecting transmitter - checks position using static rail-free report unit and, after leaving rail section, train end transmitter signal is located for comparison with theoretical data.
Inventor: KLAHN VOLKER
IPC: B61L1/14
Filed: 1992-10-20
Abstract: Transmitters (S1,S2) are arranged at the end and at the beginning of the train which send signals to section-side receiver equipment (E) as they are passed which, together with signals of section-side rail free report units, are transmitted to an evaluation installation (AE) which has memories for receipt and comparators for comparison of predetermined parts of the data. Elements (A1,A2) of the free report units are arranged suited to the receiver equipment (E), and the signals of the train end transmitter can only be evaluated in a short time period after free report from the rail. A validity criterion is issued when, in the short time period after rail free report, signals are received from the train end transmitter.

Title: Electronic changeover device for DC-excited AC solenoids (coils) with a pick-up winding and a holding winding
Inventor: QUERFURTH ANDREAS DIPL ING
IPC: H01F7/18
Filed: 1993-03-12
Abstract: The invention relates to an electronic changeover device for DC-excited AC solenoids with a pick-up winding and a holding winding. According to the invention, when the solenoid control voltage is present, a sensor (V10) detects the marginal field of the solenoid and, when the marginal field strength falls below a predetermined threshold value, initiates the changeover from pick-up to holding magnetomotive force. The specified circuit manages without an auxiliary contact and is configured in a very simple manner due to the digital changeover from pick-up to holding operation. In addition, the functions of overvoltage limitation, time-dependent protective disconnection, undervoltage protection, polarity reversal protection and temperature protection can be implemented with little expenditure. By switching the changeover device into the standby mode, the interference immunity is increased and the current consumption after completion of the switch-on operation is reduced. The entire control circuit including the sensor can be accommodated in a plastic cup, which is fixed on the outside of the apparatus, the sensor coming into the region of the solenoid marginal field which forms (Fig. 1). <IMAGE>

Patent DE-4332521-A1 (DE)
Title: Device for determining the incidence direction of optical radiation
Inventor: WENZEL WOLFGANG DR RER NAT
IPC: G01J1/04
Filed: 1993-09-24
Abstract: A device which consists of a light-proof housing is used for detection and direction determination of optical radiation, for example of laser radiation. The housing has a slotted shutter on the front through which the optical radiation enters and strikes photodiode arrays which are fitted on the wall opposite the front. Specific angular ranges are assigned to the closely adjacent photodiodes, which are arranged in the form of rows. If, in the case of such a device, the optical radiation is incident at an angle which becomes increasingly acute with respect to the plane of the shutter, the width of projection of the slotted shutter becomes greater and, in the case of closely adjacent photodiodes, a plurality of photodiodes are unintentionally illuminated at the same time. Unambiguous angle assignment is therefore possible only by means of additional signal processing. In the case of the device according to the invention, the optical radiation enters through an opening (3) onto a concave-domed surface on whose inside a plurality of opto-electrical transducers (D) are arranged which are each assigned to one incidence angle range. If the device is designed such that a plurality of opto-electrical transducers (D) which are located alongside one another are always illuminated at the same time, then suitable signal processing drastically reduces the false alarm rate. <IMAGE>

Title: Pipe connection with length compensation
Inventor: DEMBINSKI NORBERT
IPC: F16L39/00
Filed: 1993-10-11
Abstract: In order to achieve length compensation in the case of pipe connections, it is known to plug pipes one into the other and to make provision for a frictionally locking connection. According to the invention, this frictionally locking connection is, however, replaced by a positively locking connection, in that provision is made, on the outer circumference of the pipe to be connected, for a profiling into which a supporting ring is pressed via clamping elements. This produces a play-free positively locking connection.
