Title: Release of shunting track routes
IPC: B61L21/06
Filed: 1953-02-27
Abstract: 760,800. Railway route section releasing. STANDARD TELEPHONES & CABLES, Ltd. Feb. 27, 1953 [March 7, 1952], No. 5570/53. Class 105. In a railway signalling and points control system for releasing interlocked marshalling routes in which a marshalling route consists of a plurality of track sections, some of which include points, the release is effected when a " cut of cars " reaches the last section of the route, the release being effected whether or not that " cut of cars " has vacated all the track section of the route other than the last, whereby each of the route track sections including points is available for use in establishing other routes as soon as the " cut of cars " has reached the last section. The setting of the marshalling route is effected by a route setting key which closes a normally open contact FT in the circuit of a latch relay FF which is the route locking relay for that route. If the route is properly set the latch relay FF has its operating winding energized from contact FT and the marshalling signal can now be cleared. When a " cut of cars " occupies track sections TS1, TS2 and the track relays for these sections are released, a relay FA1, Fig. 2, is operated over contacts W1, W2 of track relays for track sections TS1, TS2, which contacts are now closed, and the closed contact W3-1 of the track section TS3. When relay FA1 is operated a stick circuit is completed via its own front contact fa1-2 and contact ff of the latch relay FF. The contact fa1-4 on the operating circuit of the operating winding of the latch relay FF is opened. When the " cut of cars " is in section TS3 and commences to enter section TS4, position a, Fig. 1, the track relays of section TS3 and TS4 are released so relay FA2 operates through a front contact fa1-4, which was closed when relay FA1 operated, contacts W3-2 and W4 of the track relays for section TS3, TS4 which close on release of their relays due to track occupation. When relays FA1, FA2 have been operated a circuit is completed over front contacts fa1-3, fa2-2 for the releasing winding of relay FF, the armature of relay FF returns to normal and the route locking is released. The release of relay FF breaks the relay FA1 stick circuit at contact ff which relay releases to break the-operating circuit for relay FA2 at fa1-1. In an alternative arrangement the operating circuit of relay FA1 can be completed when sections TS2, TS3 are occupied, but section TS4 is not. In a further modification, a normally closed contact of the track relay of the section TS1 can be included in the operating circuit of relay FA2 which cannot operate until the " cut of cars " has reached position b, Fig. 1. Thus, when sections TS3, TS4 are occupied and TS1 is vacated, Fig. 3, relay FA2 operates via contacts W3, W4-2, W1 and fa1-2 of the track relays of sections TS3, TS4, TS1 and of relay FA1.

Title: Improvements in weighing machines with taring devices
IPC: G01G23/16
Filed: 1944-04-04
Abstract: 606,104. Weighing-apparatus. BERKEL AUTO SCALE CO., Ltd., and SALTERS, J. B. M. April 4, 1944, No. 6249. [Class 143] A weighing-machine for weighing the contents of containers has an adjustable taring device comprising load means movable to and fro to vary the tare load, and an adjustment member connected to the load means and movable to and fro to adjust the load means and counterbalance the container, said member being supported by the goods side and movable by the operator by or in the act of moving to and fro the container placed on the goods side. The machine comprises a beam 1 with indicating means of the pendulum type including pointer 2 and scale 3, and a dropweight 6 applied to platform 5 when filling a container on goods platform 4. A handle 7 simultaneously effects addition of the weight 6, through an eccentric on the spindle of the valve 8 rocking the lever 19, and opening of the said valve controlling the flow of filling liquid to the container. A subsidiary weight 11 is pivoted on the support 5a and attached to a steel ribbon 16 engaging a cam surface thereof and connected at its other end to an arm 12 on the platform support 4a frictionally slidable on a base 4b. A container is placed between angle abutments 14, 15 on platform 4 and moved longitudinally of the beam to slide the arm 12, swinging weight 11 until the pointer 2 is at zero. Lever 7 is then operated to lower the dropweight and open valve 8. Greatest relative variation in tare load is obtained with displacement of the weight 11 between vertical suspension and suspension at about 45 degrees to the support 5a. Automatic closure of valve 8 when zero is reached, after filling, is effected by an abutment 21 closing a switch 22 in the circuit of an electromagnet 24 which raises an armature carrying a projection engaging a recess in the eccentric on the valve spindle to hold the valve open. Dropweight 6 is at the same time returned to its raised position. In a modification; a V-shaped cradle, one side formed by a middle link and the other by a pair of outer links of about half the length, carries the subsidiary weight at its apex, on a hinge pin. The three links are mounted on knife-edges, the side links on a member carried by the weights platform support and the other on the end of arm 12. This arm may be forked so that a container registers between the prongs of the fork. The middle link may be replaced by a cord passing over a pulley on an extension of the goods platform. Instead of a subsidiary weight, a suspended chain may be used which may also pass over a pulley. The adjustable arm and the suspension means may be on the goods side of the machine. The adjustment member may be movable to and fro laterally to effect the tare adjustment or, for use with containers having small orifices, may take the form of a turntable.
