Patent DE-4329238-A1 (DE)
Title: Circuit for activating and deactivating intermittent train control devices for railways
Inventor: THURM WOLFGANG DIPL ING
IPC: B61L7/10
Filed: 1993-08-24
Abstract: In order to control intermittent train control devices (PZB), monitoring relays (Ugn1, Uge1) which are near to the signals are used in a known manner. These monitors are constructed as bistable relays, the adjustment windings (1) of which are respectively connected into the feed circuit of the signal lamps (Lgn, Lge1) for the travel indications and the restoring windings of which, connected in cascades, are arranged in the circuit of a signal lamp for the stop signal indication. After a reversing order has been triggered, the setting windings (1), respectively bringing about the reversing, of the bistable relays (Ugn1, Uge1) are switched off, the feed circuits for the respectively connected-up signal lamps being kept closed by means of a contact (Ugn1/3, Uge1/3) of the respective relays. As a result of the relay windings being switched off and bridged after they are activated, the feed current subsequently flowing across the signal lamps is completely independent of the dimensioning of the relay windings and thus does not influence the maximum distance which can be set between the light signal and signal box in any way. As a result of the switching contact position respectively assumed at the last reversing process having been stored, the signal lamps assigned to the travel indications can also be switched to flashing voltage without this affecting the actuation of the intermittent train control devices. <IMAGE>

Title: Hydrostatic variable ratio drive
Inventor: ERLACH RICHARD DIPL ING
IPC: F16H39/14
Filed: 1993-12-10
Abstract: The speed adjustment of the driven shaft (8) is produced by a change in the differential speed between the driven pump housing (3) and the axial piston/constant pump (7,9,10) connected to the output shaft. An increase in the output speed is achieved by a reduction in the delivery of the variable displacement pump (4,6,10), by changing the angle of its inclined disc (6). Disc perpendicular to the shaft (1) with the delivery zero produces the gearbox translation ratio 1 : 1. The inclined discs (6,9) and the common control disc (2) of the displacement pump and constant pump rotate with the drive speed. The drum (4) of the displacement pump is fixedly connected to the gearbox housing and the drum (7) of the constant pump is mounted rotatable in the pump housing.
