Abstract: 329,381. Dunlop Rubber Co., Ltd., Hayes, C., Madge, E. W., and Jennings, F. C. Feb. 19, 1929. Latex, treating.-Rubber goods are made by spreading, dipping, extruding while still mobile, aqueous dispersions of rubber with which has been admixed a small quantity of phenol &c. with or without a tanning agent and subsequently adding or contacting with a substance capable of reducing the alkalinity of the dispersion but free from local coagulative action to promote gelling. In an example a 60 per cent latex with an alkalinity of 0.4 per cent is compounded as follows in parts by weight. Rubber 100, sulphur 3, accelerator 0.5, zinc oxide 1, phenol 0.65, tannic acid 0.35. Formaldehyde is added to make the mixture neutral when gelling occurs within five minutes. Specifications 219,635 and 290,313 are referred to.

Abstract: 525,107. Aircraft landing gear. HEYLAND, A. H. Feb. 21, 1939, No. 5776. [Class 4] To stabilize an aircraft having a tricycle undercarriage with a forward wheel when alighting, a retractable wheel or skid is mounted beneath the tail and is lowered when alighting to offer lateral resistance to movements of the tail through its pressure on the ground. Similar results may be obtained on a seaplane by the use of a retractable tail float. The device is raised for starting the aircraft. As shown a skid 1, of which there are two side by side on a common axle 2, is retained in its lowered or raised positions respectively by pawls 3, 4. The pressure on the skid can be increased by raising the elevator.

A wheeled launching carriage upon which an aircraft is releasably mounted during a take-off run under the power of the aircraft or of propulsion means on the carriage, or both, has wheels (at least at one end of the carriage) mounted upon an axle pivotable about an axis so arranged that the application of a rolling moment by the aircraft to the carriage results in the axle being turned about its pivot axis to steer the carriage in an appropriate direction. An aircraft 15 is mounted by a pillar 14 (with freedom to align itself with the relative wind) on a carriage 10 provided at each end with bearings 16 for shafts 17, 18 inclined to the ground surface 19 as shown in Fig. 1 and fast with the axles 11, 12 of the wheels 13. If it is necessary to steer the aircraft and carriage a rolling moment is applied by the normal flying controls on the aircraft to incline the carriage laterally as shown in Fig. 4, and since the axles can move only in a plane parallel to the ground surface 19 they are inclined to the longitudinal axis of the carriage to cause a steering movement. Specification 595,464 is referred to.

Abstract: 617,173. Gas turbines for jet propulsion. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., JOHNSTONE, A. P., and WALKER, D. N. Feb. 27, 1946, Nos. 6121 and 11922. Drawings to Specification. [Classes 110 (i) and 110 (iii)] In a gas turbine jet-propulsion plant part of the exhaust is evacuated up-stream of the propulsion jet during starting and low load running. This may be done by axially moving the final portion of the jet tube so as to leave a gap between it and the up-stream portion, or, by opening valves in auxiliary exhaust outlets. The control for this action may be coupled with the fuel control. With two turbines in series the auxiliary exhaust outlets may be between the turbines. With a long jet tube, the tube is fixed at its outlet end and the gap, which occurs at low temperatures, is closed by thermal expansion of the tube. The gap may be between plain ends, or telescoping ends with perforations as ports, or between flanges having interpenetrating annular rings which provide for thermal expansion after the gap is closed. According to the second Provisional Specification, the gap may be shut by means of the thermal expansion of the support. Also a similar gap in the delivery of an axial flow compressor may be used to prevent stalling at low-speeds. Reference has been directed by the Comptroller to Specification 623,108.

Title: Fluorescent material
IPC: C09K11/68
Filed: 1936-03-02
Abstract: Fluorescent screen material comprises zinc tungstate in an exceptionally pure state, i.e. with impurities less than 1 in 10<6>. Chemically pure zinc is redistilled several times, dissolved in nitric acid, the solution neutralized with ammonia, and then made slightly alkaline to precipitate zinc hydroxide. This is filtered and washed.  Chemically pure tungstic acid is neutralized with ammonia and the ammonium paratungstate crystallized therefrom.  After washing the crystalline precipitate with water, aqua regia is added, the mixture is boiled for about four hours and the tungstic acid filtered.  The process is repeated until the impurities do not exceed one part in a million. The tungstic acid and zinc hydroxide are slowly heated together in an unglazed crucible to form pure zinc tungstate.  This is finely ground and a water suspension formed to yield a fine suspension which is allowed to settle out.
