Title: Position sensing apparatus
IPC: F16L3/205
Filed: 1965-10-12
Abstract: 1,056,504. Pipe Supports. L. S. SUOZZO. Oct. 12, 1965, No. 43315/65. Heading F2P. [Also in Division G3] Apparatus for use in supporting a load subject to angular movement in service, such as a pipe P, Fig. 3 (not shown), comprises first and second blocks 41 and 42 respectively independently slidably mounted for rectilinear movement between guide rails 27, 28 and 29 which are secured to a fixed housing H attached to a rigid support structure 15. The blocks are resiliently anchored at one end by springs 50 and 57 to the housing and are connected at their other ends by cables 76 and 70 to axially-spaced pipe straps 79 and 72, Fig. 3. The first block carries a cam plate 43 which is arranged to actuate either a switch S1 or a switch S2 mounted on the second block when differential movement between the blocks exceeds a predetermined amount, said movement being induced by tilting of the pipe in service. For example, if the right-hand end of the pipe tilts down, the first block will move further to the right than the second block due to the unequal axial spacing of the respective cable connections to a pipe support strap 68. When this differential exceeds a predetermined amount, the cam plate moves a roller 63 and its associated contact arm 62 of switch S2 down to close said switch. A reversible electric motor unit M, driving a screw jack as described in Specification 971,791 is then energized to angularly re-position the pipe. Tilting of the left-hand end of the pipe will cause actuation of the switch S1 and reverse operation of the motor unit. A pointer 55 in conjunction with graduations on a housing window 23 provides a visual indication of the pipe adjustment. In a modification, Fig. 4 (not shown), each block is coupled to the respective pipe strap by cables through an intermediate lever whose ratio can be changed. In a further modification, Figs. 5 to 8 (not shown), the blocks are coupled to cables connected to the pipe straps by pivoted linkages; the blocks in this case being slidably mounted relative to the housing for rectilinear movement in the vertical direction.

Title: A circuit arrangement for controlling a set of points in a railway installation

Abstract: 962,799. Route setting system. SIEMENS & HALSKE A.G. Dec. 21, 1960, No. 43952/60. Heading B7N. A circuit arrangement for controlling a set of points in a route setting system comprises two route setting relays each associated with one of the two settings of the points, a locking relay and two release relays each with two windings which act to prevent the unlocking of the points when a train enters a section preceding that which includes the points and until a section succeeding that which includes the points is vacated. Assuming a route from track section G1 via points section W1 and points section W3, having associated track relays GF1, WF1 and WF3, respectively, to track section G2, operation of route setting relays WSP1 and WSP3 (not shown) switch points W1 and W3 to normal and open the circuit of the resetting winding of a locking relay WVR1, Fig. 4, associated with points W1. When a train enters section G1, a first X winding of a first release relay WA1a is energized via contact GF11 of the associated track relay and a contact WSP15 of the route setting relay and contact WA1a5 disposed in the resetting circuit of locking relay WVR1 is opened. On entering points section W1 the Y winding of the relay WA1a, Fig. 2, is energized via contact WF12 of the associated track relay and this winding holds relay WA1a energized when the train leaves track section G1. When the train enters track section W3, the X winding of release relay WA1& is energized via contact WF31 of the track relay and its Y winding, Fig. 2, via contact WA1b1. Pick up of this relay opens contact WA1b5 in the locking relay reset circuit. As the points section W1 is cleared relay contact WF13 opens the circuit of route setting relay WSP1, Fig. 3, associated with points W1 (normal) and contact WSP13 of this relay opens the circuits to the Y windings of the release relays whereby relay WA1a releases. When section W3 is cleared relay WF3 releases and opens the circuit to the X winding of release relay WA1b. The release of the route setting relay and both release relays completes the circuit to the resetting winding of locking relays WVR1 and the points W1 are released.

Abstract: 1326647 Vulcanizing rubber STAUFFER CHEMICAL CO 28 Sept 1971 [28 Sept 1970] 45103/71 Heading C3E [Also in Division C1] The dispersibility in rubber of insoluble sulphur is improved by mixing the sulphur with 0À3 to 5% by weight based on the total weight of sulphur of a dispersing aid of formula wherein R 1  is an alkyl group containing from 4 to 20 carbon atoms, R 2  is a hydrogen atom, or an alkyl group of from 4-20 carbon atoms and n is an integer from 4-100. Insoluble sulphur is defined as a sulphur containing at least 30% by weight of a sulphur which is a metastable linear polymer having more than 8 sulphur atoms/ polymer chain or such a sulphur which has been treated with an oil to prevent dusting during rubber processing. The mixture may be formed by merely agitating the two ingredients at or near room termperature, or by adding the sulphur to a solution of the dispersing aid in a solvent which does not affect the stability of the sulphur e.g. CS 2  and then evaporating the solvent. The above modified sulphur is used to vulcanize rubber wherever sulphur or insoluble sulphur can be used. The rubber used is defined as an unsaturated hydrocarbon elastomer requiring a sulphur cure and natural rubber, SBR, butadiene, acrylonitrile and EPDM are mentioned, natural rubber being exemplified. Other ingredients found in rubber blends viz antioxidants, processing aids, buffers, fillers, pigments and accelerators may be present.
