Abstract: 253,519. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Weber, H. C. P.). June 10, 1925, [Convention date]. Phenol-furfural condensation products; ester condensation products.- A liquid or a solid and fusible phenol-furfural condensation product is mixed, with or without the addition of solvents and fillers, with a liquid or a solid and fusible condensation product of a polyhydric-aliphatic alcohol and a polybasic carboxylic acid. The mixture may be rendered insoluble and infusible by the usual methods or may be used as a varnish, preferably with the addition of a solvent such as alcohol. In an example, 10-30 parts of a phenol-furfural condensation product dissolved in 10 parts of alcohol are mixed with 90-70 parts of a glycerol-phthalic anhydride condensation product, also dissolved in 10 parts of alcohol, and 20 parts of a filler are added. The solvent having been evaporated, the dried composition is ground and moulded under heat and pressure to produce an insoluble and infusible product.

Abstract: 904,493. Traversers. CEMENTATION CO. Ltd. April 14, 1961 [April 27, 1960], No. 14762/60. Class 104(2). A traverser for railway lines comprises a wheeled platform having rail ramp means at one end for leading rail cars up on to the platform from an " up rail pair and down from the platform to a " down " rail pair and incorporating a turntable which can swing from an intermediate loading position in one direction to register with the up rails and in the opposite direction to register with the down rails. The device is intended for use in mine tunnels in conjunction with a mechanical loader operating at the coal face and including an endless conveyer. Two pairs of rails 1, 2 support the platform by means of wheels 4 which run on the outermost rail of each pair. The platform has a fixed part 5 supporting pairs of converging rails 11, 12, registering with pairs of rails 13, 14 on ramps 15 hinged to the chassis, the pairs of rails 13, 14 registering with the rails 1, 2.

Abstract: 669,009. Undercarriages for aircraft. EST - ETABLISSEMENT SCIENCES TECHNIQUES. June 14, 1950 [May 9, 1950], No. 14828/50. Class 79 (i). An endless track landing gear for aircraft comprises a central supporting member which pivots on the undercarriage stub axle, two arms resiliently pivoted on said support to form a main frame, a sub-frame pivoted intermediate, its ends to each end of the main frame, wheels pivoted on each end of each sub-frame, and a flexible endless track embracing the wheels. Pivotal movement of the two arms forming the main frame about the central supporting member is resisted by spring means, or a rubber, hydraulic or pneumatic buffer As shown in Figs. 3 and 4, the track assembly is carried by a member 9 pivoted on the stub axle 17. Pivoted to the member 9 at 10 are the main frame arms 11, and pivoted to the ends of the arms 11 at 8 are sub-frames 3 which carry wheels 1 at their ends. The arms 11 and sub-frames 3 are preferably duplicated, the wheels being mounted between the two sets. One wheel 1 is preferably carried by a resilient telescopic mounting 7 to tension the endless track 5, which is flexible but inextensible, e.g. a pneumatic tyre. Fig. 4 shows an arrangement of elastic devices 14 to cushion the articulation of arms 11. Pivotal movement of the sub-frames 3 may be damped by a friction device in the bearings 8. Means are provided for resiliently maintaining the landing gear at the correct angle, as in Fig. 8, whereby when landing, the back of the endless track touches the ground first and prevents too sudden a speeding up of the track. Such means may comprise an elastic member 21 (Fig. 7), embracing a fixed pin 20 on the member 9 and a pin 19 attached to the undercarriage leg ; thus the landing gear is urged in an anticlockwise direction about the stub axle 17, such rotation being limited by the face 9<SP>11</SP> of member 9 abutting the pin 19.
