Patent EP-0052221-A1 (EP)
Title: Signal-processing circuit
Inventor: GOERNE JAN DIPL-ING
IPC: G01R19/165
Filed: 1981-10-07
Abstract: A circuit for evaluating signals has an operational amplifier and a comparator, both of which are supplied by a voltage source connected to ground at one side. The reference inputs of the amplifier and comparator are respectively connected to different taps of a voltage divider also connected across the voltage source, the taps being separated by a low-resistance resistor, thus attaining a stable zero signal level at the signal input of the comparator in the quiescent state through the non-inverting input of the operational amplifier and the output thereof, the stable zero signal level exhibiting a constant voltage difference in comparison to the reference potential at the reference input of the comparator.

Abstract: In order to prevent a false signal being given in a circuit arrangement for detecting the presence of rolling stock on a track section, when a rail is grounded or fractured, a detecting circuit (31) is provided for detecting unbalance of the traction current. The unbalance detecting circuit is for association with a transmitter (20) for transmitting a track circuit current and an associated receiver (21). The unbalance detecting circuit has two current sensors (TA) which are connected to the ends of the rails (1, 2) adjacent to the receiver (21) for transmitting respective signals to the unbalance detecting circuit (31), and the unbalance detecting circuit transmits the track circuit signal to the receiver only when the signals detected by the current sensors are equal or when their difference is such as not to cause undue excitation of the receiver, and a pole change switch (30) for connection between the track circuit current transmitter and the ends of the rails associated therewith.

Abstract: The condensate of closed cycle power plantthat uses an organic working fluid for lubricating the bearings (25) of the turbine (13) is cooled to a temperature below the condenser temperature by an auxiliary cooler (42) before being supplied to the bearings. This subcooling of the lubricating liquid increases its viscosity to a value which causes the minimum thickness of the lubricating film in the bearings to be increased significantly. By increasing the minimum film thickness, the filtering demands on the lubricating condensate are reduced and the surface finish of the journals and bearings is less critical permitting the journals and bearing to be finished by standard precision grinding techniques. In a specific embodiment of the invention, a canister (19) housing the turbine/generator (31) is provided with a sump (39) for collecting liquid working fluid which is delivered to the bearings through a cooler (32) Where the prime mover (13) is coupled to a generator (31) through a gearbox (27, 28) all of which are contained in the sealed canister (19), the viscosity of the condensate may be increased to such a level that the cooled working fluid is adequate to lubricate the gearbox (27, 28) itself.

Abstract: A reel-to-reel magnetic tape drive includes a motor (14) for a tape supply reel (16) in a cartridge (16A). The free end of the tape (28) wound on the reel (16) has a leader block (29) to prevent its entry into the cartridge. For transducing purposes, the leader block is drawn along a tape path (27) and secured to a take-up reel (24) driven by a motor (22). The motors have tachometers (12 and 20) providing signals to a controller (10). 
     Reels of magnetic tape for use in the reel-to-reel drive may suffer from inter-layer slip, if the reel has gone through environmental changes. This slip will cause errors to occur in the reading of the tape, because a constant tension and velocity and an accurate position is required in the reel-to-reel drive. To check whether the tension of the tape needs to be refreshed, the end of the tape is firmly held while the reel is driven in a reverse direction against the firmly held end of the tape. A detected reverse rotation indicates an interlayer slip condition. The tape tension is then refreshed by unreeling the tape and rereeling with the correct tension applied. The reel of tape is then ready for operation.
