Title: Improvements relating to route setting apparatus for railways
Inventor: BROWN ANDREW
IPC: B61L19/06
Filed: 1949-08-05
Abstract: 695,542. Railway route-setting apparatus. STANDARD TELEPHONES & CABLES Ltd. July 28 1950. [Aug. 5 1949] No. 20405/49. Class 105. In a route setting apparatus the detector means for track-section occupation control a relay whereby all the movable elements of the route e.g. the various points are simultaneously released as soon as the section containing the last of the movable elements (points) is vacated. Fig. 1 shows a track layout and Fig. 3 illustrates the control arrangements, for certain of the possible routes, whereby the release is effected. The routes are set up in known manner by sequence switch apparatus. Thus to set up the route, denoted by 4B3, from signal 4 on track A over crossover 6 at reverse to track B, points 12 at normal, fixed crossing C17, points 18 at normal, catch points 21, to signal 29, the signalman operates a push 4B3 whereby in known manner a sequence switch 5 to which this route is allocated, is driven to a position 4B3 to set up the route and clear the signal. The route is released and the various points freed when a. relay 5ZNR becomes energized and thereby causes the sequence switches 5 to be driven to the home position. The circuit to the relay 5 ZNR is from a positive source B, Fig. 3, over a back contact of a relay 5ZLR which is energized whenever the sequence switch 5 is moving, over unoperated (released, by the signalman on entry of the train) push button contacts such as 4B3, over the sequence switch 5 in its route setting position such as 4B3 and making at the J symbol contact 4B3, then over track relay front contacts 17T, 12T, 13T, a front contact of an approach locking relay 4 NPS, and a back contact of a relay 5ZCPR which is energized only when a route on the sequence switch 5 is available. When the relay 5ZNR is picked up it sticks up over its own front contact until the sequence switch reaches its home position and there opens the spearhead-symbol contact 5H ; the relay 5ZNR in known manner causes the sequence switch to be driven to its home position. It will be seen that the relay 5ZNR is energized as soon as the train directed to the route 4B3 from signal 4 on track A to signal 29 on track B and including the track sections 13T, 12T, 17T, 21T, 5T, has vacated section 17T the latest of the sections 13T, 12T, L7T which include points in the route namely the crossover 6-6, the points 12, and the points 18 ; the catch points 21 are held closed by track occupation until the train leaves their section 21T. Track, stick-relay contacts such as 13TS permit shunting-movement routes to be set up and broken down provided the shunting route does not conflict with an occupied section.

Abstract: 942,975. Melt-spinning artificial filaments. BRITISH NYLON SPINNERS Ltd. May 30, 1962, No. 20837/62. Addition to 901,398. Heading B5B. The process of the parent Specification (wherein in the melt-spinning of a synthetic linear polymer a homogeneous and laterally unconfined shallow layer of an inert gas such as steam, which may be superheated, is continuously and uniformly provided in contact with the entire surface of at least that portion of the face of the spinneret plate which contains the extrusion orifice or orifices) is modified in that the steam below the spinneret plate is provided substantially at atmospheric pressure and at a velocity just sufficient to maintain the required flow for blanketing the face of the spinneret plate. The steam may be metered from a single pressure supply thereof to a number of spinneret plates, and may be allowed to expand to substantially atmospheric pressure before it reaches the vicinity of the spinneret plates. A metering orifice within the steam supply pipe may be fitted at a position outside of the melt-spinning apparatus itself. The steam may be metered from a single pressure supply thereof to a number of spinning plates, and may be allowed to expand to atmospheric pressure before it reaches the vicinity of the plates. The metering orifice may be located at the inlet of a main steam header pipe supplying a number of melt-spinning apparatuses. The advantage of the modification of the invention of the parent Specification are the complete absence of any interference with filament flow owing to the low velocity of the steam at the spinneret face and that the gauze diffusor ring may be dispensed with and poor filament flows due to any partial blockage of the ring thereby avoided. " Wiping " of the spinneret face when " drip " occurs is also thereby facilitated.
