Patent GB-652744-A (GB)
Title: Production of artificial fibers
IPC: D01D5/00
Filed: 1947-12-31
Abstract: An organic polymeric fibre-forming material capable of being formed into fibres which exhibit crystallinity, is extruded into a liquid setting medium to form initially highly plastic fibres which are subjected, as such, or in the form of threads or yarns, but before final <PICT:0652744/IV (a)/1> setting, to a pulsating field of focused high-frequency sound waves, i.e. waves having a frequency of 1000 to several times 107 cycles per second.  The sound waves may be generated by a transducer of the piezo-electric crystal, magneto-strictive, or electromagnetic type.  The fibres may be treated at all stages in their manufacture while still in a plastic state from the time of their formation to before, during or after a stretching treatment. The process may particularly be applied to partly regenerated cellulose fibres, but fibres of regenerated proteins such as casein or of cellulose esters such as cellulose acetate may also be treated.  The fibres or yarns may be subjected to the sound waves simultaneously with stretching.  As shown in Fig. 1, a trough 13 comprises two compartments 14 and 15 separated by a liquid-tight diaphragm 21, a portion of which comprises a plano-concave compressional wave lens 22, the curved face of which is a spherical surface.  Compartment 14 is supplied through pipe 16 with a plasticizing liquid such as hot water or hot dilute acid and compartment 15 contains oil in which is supported a piezo-electric crystal transducer 19, the crystal being energized by a pulsed generator 20.  The reflector 23 concentrates the beam of waves from the crystal at the focal point 24, through which the fibres pass on their passage through the bath via rollers 11 and 12, stretching being effected between rollers 11a and 12a. Another similar example is given, in which fibres are subjected to the sound waves in the spinning bath, and in a further example the plano-concave compressional wave lens has a concave face of cylindrical shape which itself constitutes the liquid-tight partition between the two compartments of a spinning cell. Specification 648,830 is referred to.  The Specification as open to inspection under Sect. 91 refers to the manufacture of fibres by dry spinning.  Also, it is not limited to the use of focused sound waves and includes examples in which air is the medium through which the fibres are subjected to the sound waves.  This subject-matter does not appear in the Specification as accepted.

Title: High vacuum pumps
IPC: F04D19/04
Filed: 1936-12-21
Abstract: 475,840. High-vacuum pumps. GAEDE, W. Dec. 21, 1936, No. 35042. Convention date, Dec. 21, 1935. [Classes 8 (i) and 71] [Also in Group XXVI] A high - vacuum pump has a working chamber separated from the suction passage, to which additional air or gas is supplied so that the vapour drawn from the space being evacuated is prevented from or hindered in its condensation. Fig. 1 shows a piston pump drawing from a source 8 through a chamber 6 in which a slide valve 7 controls communication with the ends of the pump cylinder. The pump delivers to a chamber 71 formed in the slide valve, to which extra gas is supplied through a regulable valved passage 11, the mixed gases passing off by an outlet 9. Fig. 2 shows a rotary sliding-vane pump in which the gas inlet 26 is automatically controlled by a diaphragm 23 subject to the vacuum in the inlet so that gas is admitted increasingly during the later stages of evacuation. Fig. 8 shows a rotary hinged-abutment pump with manually controlled gas inlet 123, immersed in an oil bath. Sufficient gas is admitted to prevent condensation of the vapour in the bubbles formed by the discharged gas. The surface of the liquid may be kept free of water vapour by a draught of air blown across it. Two-stage pumps may be employed, one stage being a diffusion pump. Fig. 10 shows a molecular pump in which a cylinder 56 rotates in a cylindrical casing formed with helical grooves through which the rotation draws the gas from an inlet passage 58 ; extra gas is supplied to the ends of the casing through a throttled passage 64 ; the mixed gases and vapour, including oil vapours from the bearings, are drawn off through a delivery passage 63 by a second vacuum pump. Specification 385,192, [Group XXVI], is referred to.

The cutter 21, which may be a blade or saw, is vertically movable and is mounted on the carriage. A similar cutter can be fixed on the outlet side of the former 3 (Fig. 3). In another embodiment, Fig. 4, the measurement of the length of the residual arm R53 is transmitted to a given line 36 at the tube feed point 37 before the next tube is introduced into the bending machine. The bending programme for the next tube is then transmitted as an intermediate programme from the line 36 to a device 45 on which positions 39<SP>1</SP>-44<SP>1</SP> represent the places which are required for the next bending operations. Pipes having ends 46-51 are aligned with their other ends on the line 36 so that when the pipes are fed into the bending machine the ends 46-51 are compared with positions 39<SP>1</SP>-44<SP>1</SP>. In the example shown in Fig. 4, the pipe with the end 51 is unsuitable because its end falls within the bending zone 44. In both embodiments the tubes are joined by welding.

Title: Improvements in and relating to closures for bottles
IPC: B65D51/16
Filed: 1936-12-28
Abstract: 486,673. Stoppers &c. PAROZONE CO., Ltd., and BARR, S. W. Dec. 28, 1936, No. 35521. [Class 125 (iii)] A closure for bottles comprises a washer pervious to gas, and a cover for the washer having one or more passages therein, the cover and washer being maintained in such position that a space always exists between them. The closure may be formed by a cap adapted to screw or to be otherwise secured to the neck of the bottle, and a gas pervious washer with means whereby it may be clamped on the rim of the bottle neck and by which a space is maintained between the perforated top of the cap and the washer. The clamping device for the washer may extend over it to a considerable extent so as to prevent the washer from being blown into the cap by the pressure within the bottle. The perforations in the cap may be at the ends of downwardly extending nipples so that if the bottle is held in inverted position and a small quantity of liquid should leak through the washer, it will be trapped within the space formed by the head of the cap. As shown in Fig. 4, the cap a has a central downwardly extending projection c at the foot of which is a narrow passage d. The cap is screwthreaded at e so that it may be screwed on to a bottle neck. It is also screw-threaded at f to receive the cylindrical member g the base h of which has an opening i. The opening is of such shape that it may receive a key for screwing member g into the cap. A washer j of gas pervious material such as sponge rubber is clamped between the rim of the bottle neck, and the base h. The washer should not permit passage of liquid or should only permit liquid to pass at such very slow speed as will be of no practical importance. Vapours given off by the liquid are allowed to pass through to chamber k and thence through passage d to the atmosphere. As shown in Fig. 9, the cap is formed by two portions l, n which when screwed together form a space u between the washer t and the top of the cover. The washer is clamped between the top of the bottle and the diaphragm r which has an opening s. As shown in Fig. 12, the cap has an internal shoulder v against which rests a rigid disc w having an opening x. The sponge rubber washer is clamped between the top of the bottle and the disc.
