Abstract: 1436768 Moulding fibre reinforced articles UNION CARBIDE CORP 9 July 1973 [10 July 1972 4 May 1973] 32659/73 Heading B5A [Also in Division E1] A wear-resistant surface comprises of a composite material (a) a matrix material, (b) not less than 50-90% area fraction of a hard fibrous monocarbide of a metal selected from tantalum, titanium or tungsten, the monocarbide being in the form of filaments of 2-15 microns in diameter, and being present at the composite surface as portions of filaments lying at varying orientation within the surface, the remainder of the surface being comprised of the matrix material. The wear-resistant surface material may be produced by contacting while in its liquid form a normally solid matrix material with filaments composed of the monocarbide such that the filaments are wetted by the matrix material and allowing the matrix material to return to its solid form. The filaments may be initially coated with a thin metal layer which is wettable by the liquid matrix material. Alternatively powdered matrix material may be contacted with the filaments of the monocarbide and hot pressed. The filaments may be in the form of woven fabrics, tapes, felts, chopped fibres. The matrix material may be epoxy and phenolic resin, aluminium, silver, copper, alloys thereof such as aluminium-silicon alloy, a silvercontaining brazing alloy, a copper-containing brazing alloy. In Example 2 a tape of satin weave woven fabric comprising tantalum carbide was positioned in the bottom of a mould into which epoxy resin was cast to produce upon curing an epoxy block having one surface with an epoxy matrix and tantalum carbide fibres.

Abstract: 1,215,289. Hydrostatic transmission. D. W. EVANS and E. LARGE. 30 June, 1969, No. 32861/69. Headings F2C and F2D. An hydrostatic or pneumatic transmission for a motor vehicle comprises an accumulator E supplying pressure fluid through a line H to variable displacement swash plate wheel motors J. The accumulator E is continuously charged by a pump B driven by an electric motor or other prime mover A. The pump B draws liquid from a reservoir C through a filter and cooling unit D. A high pressure relief valve F and valves G which close when the pressure supply fails are provided in the high pressure line H. The displacement of the motors J is controlled by pedals O, P which acts through liquid columns K, L on a follow-up servomotor 11. Valves M, N in the lines K, L are manually operated to selectively supply control pressure to the front and/or the rear wheel motors J. Each wheel motor comprises a cylinder block 5 rotatable on the wheel axle 4 integral with a port plate 1. Pistons 8 axially slidable in cylinders 6 in the block 5 carry shoes 9 which bear against the swash plate 10. The angle of the swash plate 10 is adjusted by toothed engagement of the swash plate with a cylinder block 25 of the follow-up servomotor 11. A control piston 27 of the servomotor 11 is moved axially within a cylinder 31 of the cylinder block 25 by the pressure in the liquid columns K, L. The piston 27 controls the flow of high pressure liquid to the cylinder block main cylinders which slide on fixed pistons 24 to follow-up the movement of the piston 27. Wheel-spin is prevented by a valve 29 which opens on excessive angular acceleration or deceleration of the wheel to reduce the pressure in the liquid column K or L and thus the swash-plate angle.

Title: Improvements in or relating to metal backed sintered material
IPC: F16D69/02
Filed: 1962-08-27
Abstract: In a process of forming a metal backed sintered friction material in which the backing contains holes, slots or recesses, the powdered friction material is compacted in a die shaped to form recesses corresponding to those in the backing so that after assembling the compact on the backing and sintering the composite, gaps overlapping the holes, slots or recesses are produced thus forming an interference layer. alternatively, the friction material may be compacted on to strips of refractory material such as asbestos, magnesia, alumina or clays, the shape and position of the strips corresponding to the holes, slots or recesses in the backing. In another method Al or Mg may be sprayed on to the friction material to correspond with the holes &c. in the backing and during sintering the Al or Mg is oxidized to alumina or magnesia. Alternatively, a layer of paper may be placed over the holes &c. of the backing so that on sintering the paper is burnt leaving a gap between the backing and the sintered friction material.  The backing is preferably a steel and the friction material may be a powder mixture of Fe and graphite which may also contain Pb and Sn.

Title: Improvements in circuit arrangements for telephone installations
IPC: H04M3/40
Filed: 1931-11-27
Abstract: 392,243. Automatic exchange systems. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Siemens & Halske Akt.-Ges. ; Siemensstadt, Berlin.) Nov. 27, 1931, No. 32979. [Class 40 (iv).] In a system comprising a central exchange H, intermediate exchanges K1, K2, and outlying sub-exchanges, for calls between distant sub-exchanges an amplifier Vst is automatically brought into circuit at the exchange H, the connecting-up of this amplifier and of associated balancing networks and resistance pads being controlled by step-by-step switches M1, M2, the first of which is set by a preliminary series of impulses in accordance with the origin of the call whilst the second is set in accordance with the destination of the call as determined by the setting of the selector GW2 in the exchange K2. The preliminary series of (A.C.) impulses is received by relay I1 which operates relays Cl, Bl, and repeats the impulses to magnet D1. If the impulses denote a call from a sub-exchange, wiper 10 prepares the circuit of a relay A2 controlling the connection of a balancing network LN2 and a resistance pad LV2. The first series of dialled impulses operates selector GW1 and the next series is repeated by relay 12 to magnet D2 of switch M2 and as impulses of A.C. from source WQ2 over the junction VL2 to selector GW2. If this digit, corresponds to a call to a sub-exchange beyond exchange K2, wiper 58 selects a relay A<1>4 and when selector GW2 has selected an idle outlet, relay P2 operating over a third wire of the junction VL2 energizes relay A<1>4 which in turn completes a circuit for relays A2, E, F, over a wiper of selector GW1. Relays A2, A<1>4 connect up the networks LN2, LN4, and the resistance pads LV2, LV4 and relay F starts a hunting switch VW which connects up an idle amplifier Vst. Relay U then operates to complete the talking connection through the amplifier. Specification 381,597 is referred to.
