Title: Improvements in wagon speed control assemblies
Inventor: WALLBANK GEORGE
IPC: B61K7/02
Filed: 1966-08-23
Abstract: 1,202,694. Retarder control system. STRACHAN & HENSHAW Ltd. 23 Aug., 1967 [23 Aug., 1966: 9 Dec., 1966], Nos. 37807/66 and 55262/66. Heading B7N. [Also in Division F2] In an arrangement for controlling the speed of a railway wagon and hence the spacing of wagons in, e.g., a hump yard, a plurality of speed control devices are provided spaced along the track and these devices are controlled in a timed sequence which is a function of the required speed. The speed control devices may be hydrodynamic retarders or they may be hydrodynamic accelerator elements. The speed control devices A-1 are disposed along the track as shown and are controlled when a wagon operates treadle 42. The control comprises a stepping switch 68 which is driven by motor 44 at a speed set by variable resistor 75 which is a function of the required wagon speed. The switch actuates solenoids 40 &c., in turn which control devices A-1 in sequence. A further control circuit operated by logic elements is illustrated in Fig. 6 (not shown). Where the devices are hydrodynamic retarders, these are normally set to their braking condition until actuated via the switch when they offer no resistance so that only wagons travelling above the set speed are braked. Where the devices are hydrodynamic accelerators these are only energized after actuation via the switch so that only wagons travelling below the set speed are accelerated. The devices may be a combination of hydrodynamic retarders and accelerators. The hydrodynamic retarders may be of the type described in Specification 784,543, with the addition.of a solenoid 40 for opening the valve controlling fluid flow between the ends of the cylinder. The hydrodynamic accelerators are described in Specification 1,185,639 and are controlled by solenoid operation of a valve in the high pressure fluid input.

A vacuum regulating valve comprises a diaphragm 17 adjustably loaded by spring 65 acting in opposition to spring 58. When the system is idle, spring 58 forces the diaphragm away from seat 24 whereby, when line 25 is connected to a vacuum source 26, the latter evacuates chamber 18 until the pressure difference thereacross aided by spring 65 seats the diaphragm.
