Patent GB-561402-A (GB)
Title: Improvements in imparting shrinkage qualities to textile materials of regenerated cellulose
IPC: D06M11/38
Filed: 1942-11-13
Abstract: Textile materials consisting of regenerated cellulose yarns in associated or unassociated form, produced by saponifying stretched artificial yarns having a basis of an organic acid ester of cellulose, are impregnated with a solution containing between 30 and 75 per cent by weight of a mercerising agent which is a base, this solution having a shrinking action on the yarns; the base is neutralised immediately after impregnation by treating the yarns with an acid, and the acid is then washed out of the yarns.  The treated yarns or fabrics undergo considerable shrinking when they are dried from the wet state.  The wet fabrics may thus be fixed over a framework of an aeroplane wing, fuselage, tail, or other part, or of a lamp-shade or screen, and when dried they become taught owing to the shrinkage which takes place.  The treatment with the base improves the extensibility of the yarns, and the immediate neutralisation of the base by acid gives products of improved tenacity.  The cellulose ester yarns may have been stretched in presence of dioxane or other organic swelling agent or in presence of steam or hot water.  The mercerising agent used for treating the regenerated cellulose yarns may be sodium hydroxide, or potassium hydroxide in aqueous or alcoholic solution.  Dilute mineral acid such as hydrochloric or sulphuric acid or an organic acid such as acetic acid may be used for neutralising the base.  After washing, the materials may be dried in a hot drying chamber.  The dried fabrics may be coated with cellulose ester or other dopes.  Specification 501,768 is referred to.

Abstract: 946,745. Engine mountings on vertical take-of aircraft. ROLLS-ROYCE Ltd. May 12, 1960 [May 12, 1959], No. 16333/59. Heading B7G. [Also in Division F1] A jet propulsion gas-turbine engine is mounted for rotation about an axis at right angles to its longitudinal axis in which means are provided for retaining the engine in a horizontal position relative to the longitudinal axis of an aircraft, the said means comprising interengaging looking members on the aircraft and engine which are spaced from the axis of rotation of the engine whereby aerodynamic loads produced during forward flight of the aircraft are transmitted through said locking members to the aircraft structure. The engine 10, housed in a nacelle 20, is mounted at the tip of a wing 22 for rotation between horizontal and vertical positions by a shaft 24. The outer end of the shaft carries a bell-crank lever 26 having arms 30, 36 respectively attached to the engine by means of a roller 34 and to one end of an extensible link 38, the other end of which is attached to the wing at 40.

Abstract: 974,112. Perforating plastic &c. materials. J. V. ABOM. May 5, 1961 [May 9, 1960], No. 16373/61. Heading B4B. A method of perforating thin sheets of synthetic plastics and like material comprises placing the sheet material 1 on to a smooth backing 2 and forcing a punch 3 through the sheets in such a way that the punched-out material is pressed into a recess formed in the backing by the punching operation. The backing or die 2 can be formed of wood, layers of paper over wood, rubber, plastic material, cork, leather or some soft metal such as tin and lead. In the embodiment shown in Fig. 3, plastic sheeting 1 to be perforated is wrapped several turns around a roll 7, and a plurality of punches 3 are radially mounted on a wheel 8 which is adopted to perform the punching operation by co-operation with the roll 7 as the latter is rotated. The wheel and roll may be moved axially relative to each other at a predetermined rate, such movement being intermittent and only when the punches are clear of the sheeting. The punches are preferably of involute gear tooth profile.

Patent GB-790759-A (GB)
Title: Trimethylolethane
Filed: 1955-06-08
Abstract: Trimethylolethane is produced by a process comprising continuously forming an aqueous alkaline solution of formaldehyde and propionaldehyde, passing it first through a region in which its components react to form trimethylolethane, then through a region in which the pH of the solution is reduced to no more than 7, and next through a region in which unreacted formaldehyde is distilled off, and recovering trimethylolethane in crystal form from the solution. The preferred alkali is sodium hydroxide. Preferably an excess of formaldehyde is used, e.g. about 5 to 15 mols. of formaldehyde for each mol. of propionaldehyde. Advantageously the reaction vessel is operated adiabatically.  The solution leaving the reaction vessel is alkaline, generally having a pH of 9.8 to 10.5.  The pH is reduced to not more than 7 by the addition of acid materials, e.g. formic acid, acetic acid, sulphuric acid or phosphoric acid.  The mixture is then distilled under pressure and advantageously the formaldehyde distilled off is recycled to the mixing zone.  After the distillation the aqueous reaction mixture containing trimethylolethane and sodium formate is treated for the recovery of crystalline trimethylolethane. In one procedure it is separated by adding an organic solvent for the trimethylolethane, e.g. an alcohol such as n-propyl alcohol or isopropyl alcohol, and separating the organic phase from the aqueous phase.  The trimethylolethane may be recovered from the organic phase by heating it in the presence of added water to remove the organic solvent and crystallizing out trimethylolethane from the aqueous solution so produced. Alternatively the trimethylolethane may be separated from the reaction mixture by heating the mixture and evaporating water therefrom until the water content is about 30 to 40 per cent by weight and then cooling so that the trimethylolethane crystallizes out.  The crude crystals so obtained may be freed from sodium formate by treatment with a solvent for trimethylolethane such as methanol, ethanol, propanol or isopropanol.  These two methods of separating trimethylolethane from the reaction mixture may be combined together.  Specification 790,760 is referred to.

Filed: 1929-05-28
Abstract: 313,125. Lift-A-Kar Corporation, (Assignees of Hard, M. W.). June 7, 1928, [Convention date]. Stands or supports comprise removable ramps, a movable stand C for the front. axle and a collapsable stand D for the differential in the back axle. The front wheels of the vehicle are driven up the ramps 9, B, and then descend the ramp 22. During the descent the axle d comes to rest on the stand C which is fitted with wheels running on rails 13 located between the ramps. The stand therefore moves forward. At a certain point a cross bar 42 engages a catch at the end of a rod 69 to which the links 76, 79 of the stand D are pivoted. The saddle 75 is loosely supported on a linkage connected by a link 82 to a fixed part of the frame. When the rod 69 is pulled forward the saddle 75 is raised to take the weight of the back axle. The catch on the rod 69 presently falls and secures the stand D in position, the stand C continuing its travel. When the differential rests on the saddle 75 the latter is slightly depressed whereby the members 15, which have hitherto been locked bv a bolt 32, are released, and thrown backward out of the way by the action of the rotating wheels.

[Class 118 (ii)] [Also in Group XL] Relates to the use of navigation lights on night-flying guiding aircraft to assist accompanying aircraft to keep relative adjacent station. According to the invention, the guiding aircraft has combined therewith a lamp so mounted as to flood light a surface on the aircraft specially treated to emit radiant light visible in predetermined directions from an accompanying aircraft without the lamp being directly visible. As shown, ultra-violet-ray lamps 237, 239 have. optical systems to produce beams for flood lighting narrow strips 233, on the wings and tail plane of the guiding aircraft. The strips 233 are roughened and treated with fluorescent paint containing material activated by the ultra-violet rays from a mercury-vapour lamp having means for varying the intensity of floodlight. The surfaces may be illuminated with different colours to provide a code of signals. Specifications 574,970, [Group XI], and 575,093, [Group XL], are referred to. The Provisional Specification also describes the use of lamps having narrow divergent beams spaced apart on the guiding aircraft so that the beams overlap at predetermined distances from the aircraft in a vertical, lateral or longitudinal direction with respect thereto. The lights visible to port and starboard and fore and aft of the guiding craft are of different colours and serve as station signals for the accompanying aircraft. A single light source with an optical system to produce a number of beams of different character may be provided.
