Patent GB-791391-A (GB)
Title: Coloured cellulose acetate textile materials
IPC: D06P3/48
Filed: 1955-01-25
Abstract: The wash-fastness and other characteristics of textile materials of cellulose acetate having an acetyl value of at least 59 per cent, calculated as combined acetic acid, which have been dyed with, for example, a cellulose acetate disperse dyestuff, preferably of the "high temperature, slow dyeing" type, are improved by subjecting the dyed materials to a heat treatment. The heat treatment may be effected with the textile in the relaxed condition or under tension, and suitable heating media are hot air, saturated or superheated steam, hot oil, molten metal, infrared radiation, a high-frequency electric field and heated rolls or platens.  The heat treatment may also be effected at atmospheric, superatmospheric or subatmospheric pressures.  Dyeing is effected in a heated aqueous medium, preferably in the presence of a dyeing assistant or mixture of dyeing assistants as described in Specification 791,392, these assistants, if desired, being applied to the textile prior to its entry into the dyebath. Any stiffness of the treated textile may be removed by mechanical working or a finely divided solid, e.g. silica, may be applied to the textile before the heat treatment.  Numerous suitable "high-temperature, slow-dyeing" disperse dyestuffs and some "low or medium temperature" disperse dyestuffs are specified. To reduce the tendency towards acid-fading the usual nitrogenous inhibitors employed for the treatment of acetone-soluble cellulose acetate, several of which are specified, may be applied to the textile before, during or after dyeing, as also may antioxidants such as tertiary butyl hydroquinone and alkylated phenols.  The usual finishing agents, e.g. silicones, waxy polyethylene, waxy sulphonated fatty materials, waxy cationic long-chain amines, finely-divided silica or titanium dioxide and various resinous or resin-forming condensates, may be applied to the textile before or after heating and, in the case of silicones, before dyeing. The process is also applicable to textiles containing a mixture of highly acetylated cellulose fibres with fibres of wool, cotton, rayon, glass and asbestos.  Examples are given.  Specification 758,442, [Group IV (a)], also is referred to.
Patent GB-498364-A (GB)
Title: Process for the manufacture of vessels adapted for hermetic closure
IPC: H01J5/24
Filed: 1938-01-24
Abstract: 498,364. Uniting metal to vitreous material by heat. EGYESULT IZZOLAMPA ES VILLAMOSSAGI, R. T. Jan. 24, 1938, No. 2255. Convention date, Jan. 22, 1937. [Class 36] [Also in Groups XI Mid XXIII] In the manufacture of vessels adapted for hermetic closure, such as electric discharge tubes which may have either glass or metal bulbs, or electric incandescent lamps, wherein a base which is composed, at least in part, of glass or glass-like material and which is of disc shape at least in its peripheral region where it is subjected to fusion when being fused to the bulb, the whole or a preponderant part of the heat which is necessary in the production of the base or in its fusion to the bulb or vessel, is supplied in the form of radiant heat. The radiant heat is preferably produced in an electrically heated furnace. The base may be made from a glass tube 1, Fig. 1, which is placed upon a support 2 coaxially with an exhausting tube 3 which rests upon a support 4, these supports being movably vertically by means not shown. A series of holes 2b are provided through the support 2 for the passage of current supply wires 5 which rest upon a support 6; alternatively the holes 2b may be closed at the bottom. Radiant heat is supplied to this assembly by a furnace comprising a tube 7 of porous ceramic material around which is wound a chrome-nickel resistance strip or band 8 connected to current supply leads 8a, 8b. The tube 7 and resistance 8 are encased in a gas-tight jacket 9 with a pipe-connection 9a through which a current of hydrogen can be introduced. Loose heatinsulating material is packed within the jacket 9. Hydrogen diffuses through the pores of the ceramic tube 7 and, igniting on contact with air, burns in the interior of the furnace. The tube 1 is thus softened by the radiated heat, the upper end of the exhausting tube 3 also being softened either by raising the support 4 to bring the tube 3 into the dotted line position, or by lowering the tube 1 relatively to the exhausting tube. The softened glass is then pressed by a tool admitted through the furnace cover 10 to form a discshaped glass base with the wires 5 sealed therein. This glass base, or a disc-shaped glass base produced by other methods, may be sealed to the bottom end of a bulb 14, Fig. 4, by supporting them on a member 15 within the furnace shown in Fig. 1, and heating them until they are softened, whereupon bi-partite or mult-bi-partite tools 16, 17 are pressed radially inward while, at the same time, the vessel is subjected to internal pressure by means of an inert gas, e.g. nitrogen admitted through the tube 3. Specifications 487,197 and 490,632 are referred to.

Abstract: 620,817. Two-part couplings. TURNER ELECTRICAL INSTRUMENTS, Ltd., E., and PECK, G. T. Jan. 27, 1947, No. 2523. [Class 38 (i)] Access to the live blade contacts 17 of a socket is prevented by a hinged gate 22 which locks the socket entry when the plug 11 is withdrawn. The socket comprises a sheet-metal rectangular channel member 10 having a flange 12 welded to its mouth and braced at its rear end by a bridge piece 13, and carrying an insulating block 16 carrying the blade contacts 17 and a locating pin 18. The flange 12 has a tongue 26 pivotally supporting the gate 22, which is closed by a tension spring 27 attached to the bridge 13. Pairs of detent levers 30A ... 30F, pivoted on, and extruding through slots in, the three sides of the channel 10, have notches 35 which engage the periphery of the gate to lock it closed under the action of bifurcated leafsprings 37 bearing on pins 38 on the levers. To ensure automatic locking action and non- overshooting of the gate, the engaging corners of the detent levers are rounded, the front sides of the notches are higher than the rear, and a stop 46 is provided on the gate. Further, the slots are slightly wider than the gate thickness and inclined to engage the correspondingly-bent edges of the gate with a hooking action. The plug 11, comprising a sheet metal shell, is a sliding fit in the socket and has a key 21 engaging a keyway 19, 20 in the channel 10, and a bore 43 receiving the locating pin 18. Insertion of the plug depresses the detent levers and opens the gate, Figs. 3, 5. Alternatively, the leaf-springs 37 may have their free ends bent and notched and extending through slots in the channel to take the place of the detent levers. Further, more than one gate may be provided and the plug and socket may be of trapezoidal section.

[Class 108 (iii)] A shock-absorbing suspension device, particularly for the wheel-carrying leg of an aircraft undercarriage, comprises two annular chambers 34 and 35, 36 of different crosssectional area formed between a cylinder 19 and a two-diameter plunger 13, 22, a piston 20 which separates the chambers and is moved on relative movement of the plunger and cylinder to increase the length of one chamber and simultaneously reduce the length of the other, a floating partition 29 in the chamber 35, 36 confining compressed gas in the portion 36, and damping liquid filling the chamber 34 and the chamber portion 35, means being provided to permit controlled flow of liquid past the piston as the plunger slides along the cylinder. As shown, the upper and lower parts 22, 13 of the plunger are secured to the piston 20 and are slidable respectively in cylinder bushes 23, 27, the downward movement of the part 13 being limited by the engagement of a stop collar 25 thereon with the bush 23. In known manner, a valve 33 controls flow of liquid through passages 32 in the piston, permitting relatively free flow on compression of the shock absorber, when liquid is forced from the chamber 34 to the chamber portion 35 compressing the gas in the chamber portion 36, but restricting the flow on extension when the gas expands to force liquid back to the chamber 34. The plunger part 22 may be secured to the bush 23 and slidable relatively to the piston. In another modification, the gas in the chamber portion 36 is contained in a flexible bladder of enless tube form. As applied to an aircraft leg, the plunger part 13 carries the wheel axle and, to prevent turning, is connected by a V-linkage in known manner to the cylinder.
