Title: Process for the preparation of rubber hydrohalide dispersions
IPC: C08C19/16
Filed: 1947-10-23
Abstract: Acid-stable aqueous dispersions of polyisoprene, polydimethylbutadiene, polymethylpentadiene or a copolymer of isoprene and isobutylene, are reacted with a hydrohalide.  The product may be evaporated, or coagulated with alcohol, acetone or dioxane and then vulcanized, or modified by addition of butyl stearate, diphenyl guanidine, hexamethylenetetramine, magnesium oxide, calcium oxide or lead oxide.  Specification 594,938, [Group V], is referred to.ALSO:Rubber hydrohalide dispersions are obtained by reacting an aqueous rubber dispersion of a type which is not coagulated with an acid, with a hydrohalide.  The product may be evaporated, or coagulated with alcohol, acetone, or dioxane and then vulcanized. The latex is stabilised by adsorption displacement; or by pretreating either by pouring into an excess of acid of a certain strength and then stabilising with casein, saponin, or haemoglobin or by adding a cationic soap such as the bromide or chloride of N-cetylpyridinium, the alkali salt of methyl oleylamide ethyl sulphate, or the acetate, hydrochloride or methosulphate of a (diallylaminoethyl) fatty acid amide; or by the use of a non ionogenic emulsifying agent such as an dodecylphenol polyglycol ether; or that known under the registered Trade Mark "Emulphor." Ammonia is preferably removed by blowing with air or nitrogen or adding formaldehyde, and deproteinized latex may be used.  The latex may be a natural or artificial dispersion of natural rubber, polyisoprene, polydimethylbutadiene, polymethylpentadiene or a copolymer of isoprene and isobutylene.  The product may be modified by means of butyl stearate, diphenyl guanidine, hexamethylenetetramine, magnesium oxide, calcium oxide and lead oxide.  Specification 594,938 is referred to.

Controllers, actuating and interlocking; seriesparallel systems.-Co'mpouQd.-woimd motors for driving trolly omnibuses are controlled at lower or starting speeds by varying series resistance in the armature circuit, and at higher or accelerating speeds bv varying resistance in the shunt field circuit first with the motors in series and afterwards with the motors in parallel. In the case of a single motor, series windings are changed from series to parallel connection. The series and shunt resistance controllers are operated by separate interlocked pedals disposed in a similar manner to the clutch and accelerator pedals of a petrol motor vehicle. A reversing switch is operated by an interlocked hand lever. A brake pedal may be interlocked with the starting resistance pedal.

Filed: 1938-10-01
Abstract: 519,710. Condensation products. POLLAK, F. Oct. 1, 1938, No. 28607. [Classes 2 (iii) and 15 (ii)] Condensation products possessing wetting and frothing properties are prepared by reacting 1 molecular proportion of 2:4-diaminotoluene with at least 1 molecular proportion of formaldehyde in the presence of sufficient acid to form the di-acid salt of the anine, 'evaporating the solution down, and heating the dry residue to at least 70C. In a modification the condensation is carried out in neutral or alkaline solution and the separated condensation product is heated to at least 70C., either in the absence of acid or after having been dissolved in acid. In Examples, (1) 225 volumes of 40 per cent. by volume formaldehyde are added to 122 parts by weight of 2:4- diaminotoluene dissolved in 2 litres of normal sulphuric acid and after standing, the mixture is evaporated to dryness and then heated dry for some hours at 70-80C., to give a powder possessing wetting capabilities. with alkalies and acids ; (2) 75 volumes of 40 per cent. formaldehyde are added to 122 parts of 2:4- diaminotoluene dissolved in 2 litres of normal hydrochloric acid, the mixture is evaporated to drvness and heated in an.oven for 2-3 hours at 130C. ; (3) 61 parts of 2:4-diaminotoluene dissolved in 1200 parts of water are added to 37.5 volumes of 40 percent. formaldehyde at 33C. and the resulting precipitate is dried at low temperatures. Increased wetting properties are obtained if this product is heated to 70-80C., and if, further, it is heated to above its melting point, e.g. to 130-140C. ; better wetting properties are obtained by evaporating the acid solution of the product of example (3) and heating the residue to at least 70C., e.g. 100C.

Title: Improvements in or connected with controls of aircraft
IPC: B64C13/30
Filed: 1939-10-25
Abstract: 533,607. Linkwork. SHORT BROS. (ROCHESTER & BEDFORD), Ltd.. and HART, S. G. Oct. 25, 1939, No. 28649. [Class 80 (iii)] [Also in Groups XXXIII, XXIX and XXX] In order to compensate for changes of temperature a control cable for an aircraft is passed over two fixed guides between which is located a movable guide adapted to be displaced transversely of the cable to take up slack or to relieve increased tension. The movable guide may be actuated manually or automatically in accordance with changes of temperature, or it may be urged transversely of the cable by a spring in conjunction with a dashpot which resists movement due to momentary changes of tension in the cables. Fig. 2 shows a device, for several cables of similar length, comprising a frame 10 with two sets of guide pulleys 11 a fixed distance apart. Jockey pulleys 12 are carried by arms 13 on a shaft 14 from which depend arms 15 connected by a cross-bar 16 movable by a screw 17. The control cables are shown as lengths of chain 28 passing over the pulleys and connected by links 29. The screw 17 is turned by a shaft 18 actuated from the pilot's cockpit by a hand-wheel with which is associated an indicator drum which may be calibrated in temperatures so that the device may be adjusted in accordance with the readings of a thermometer. The jockey pulleys may be mounted and actuated individually when the cables are of different lengths. Fig. 4 shows a modification in which the jockey pulley 12 is moved by a servo-motor 31, the pilot valve of which is controlled by a bi-metallic strip 30. A locking device not shown, immobilizes the pulleys 12 should the fluid pressure fail. Alternatively the bi-metallic strip may move the brushes of a reversible electro-motor for rotating a shaft similar to the shaft 18.

Current is fed to solenoid 8 from source 10, when START switch 11 is closed and closes pinch-roller 1 up to the capstan 2, Figs. 1-2. The current is maintained while the PAUSE control 19, Fig. 1, is pulled as far as the stop 22a, Figs. 2-3. The first part of the movement dabs a brake pad 14 against the feed-spool carrier 15 (intermediate to Figs. 2 and 3) and further movement by the hook-member 20 rocks the lever 13 against the pivotal action of the engaged pad 14 to partly retract the armature 7 from the solenoid 8 and sufficiently retract the pinch-roller 1 from the capstan to provide the PAUSE facility, Fig. 3. On release of the PAUSE control, the solenoid restores the feed and retracts the pad 14 (Fig. 2 state) with minimal delay. Alternative linkage achieving equivalent PAUSE facilities are described (Figs. 4, 5, not shown) using pause brakes on the feed-spool and (Fig. 6, not shown) using the main spool brakes.

Abstract: 375,655. Automatic guns. RHEINISCHE METALLWAAREN-UND MASCHINENFABRIK, 195, Ulmenstrasse, Derendorf, D³sseldorf, Germany. Oct. 16, 1931, No. 28800. Convention date, Oct. 20, 1930. [Classes 92 (ii) and 119.] Relates to automatic guns having a single spring g for effecting both the forward movement of the breech-bolt d and the ignition movement of the firing-pin f and having also a cocking-member h which is inserted between the firing-pin and the bolt during the movements of the bolt. According to the invention, the cocking-member h serves also as a manually actuated sear and is prevented from movement to release the firing-pin until the breech bolt is closed and locked. The invention is shown applied to a gun in which the barrel recoils a short distance to rotate a locking ring e and permit the breech-bolt to perform its opening movement. During the return movement of the bolt the lever h pivoted to the firing-pin strikes with its arm h<2> against the rear end of a projection a<2> on the casing and its arm h<1> becomes wedged between the bolt and the firing-pin to cock the latter. Release of the lever is prevented by the surface a<2> until the breech is closed when the arm h<2> rests on a member a3 the removal of which by the trigger permits the lever to be rotated by the pressure of the spring g to fire the gun.
