Title: Process and apparatus for making pulp
IPC: D21C3/20
Filed: 1925-12-16
Abstract: 244,789. Fish, F. K. Dec. 22, 1924, [Convention date]. Pulp, preparation of.-The fibrous material is subjected to two conse.cutive boilings, one with dilute alkali containing solvent extractives such as terpenes &c., and the other at a higher temperature with a liquor which may be soda, sulphate, or other cooking liquor, air being excluded throughout the operation. The fibrous material is introduced into a digester 1 which is then exhausted. The vapours arising from the alkali liquor charged with solvent extractives and contained in a tank 2 heated to 274‹ F. are then admitted through a pipe 3. After about 15 minutes, during which time the heating of the tank 2 is continued, the alkali liquor is admitted to the digester 1 through the pipe 7 and steam is admitted through the pipe 13 for about 45 minutes to maintain the digester 1 at about 240‹ F. During this operation the solvent extractives rising to the top of the digester are blown off into the tank 2 to enrich the liquor for a subsequent operation. After digestion, the liquor is blown back by steam into the tank 2 and after draining with the aid of a suction pump 31, liquor from a tank 40 which, has been heated to the desired higher temperature is admitted to the digester 1 and the temperature raised to about 337‹ F. and maintained for 4-7 hours. After this treatment the used liquor therefrom is returned to the tank 40. The material then receives a washing by treatment with liquor from the tank 2 at about 285‹ F. for about 30 minutes, and is then drained and removed from the digestier. Part of the used liquor in the tank 40 is drawn off to a centrifugal machine 49a to separate lighter and heavier portions. The separated matter there obtained is incinerated to recover chemicals.

Patent GB-990692-A (GB)
Title: Foil production
Inventor: SMITH HUGH ROSCOE
IPC: C23C14/00
Filed: 1962-08-24
Abstract: A method of continuously producing foil comprises vapour depositing a material such as Ti, Ta, W, Cu, Al, a metal oxide or a dielectric on to a moving substrate and then peeling off the deposit in the vacuum chamber and removing the foil from the chamber by passing it through differential vacuum stages.  The substrate may be treated with a wetting agent or oil prior to the deposition of the foil material in order to limit the adhesion of the foil material.  In some cases e.g. stainless steel as the substrate this treatment is not necessary. Glass may also be used as a substrate and multi layers may be deposited to form laminated foils e.g. Cu on stainless steel followed by a dielectric material on the copper.  In the formation <PICT:0990692/C6-C7/1> of metal oxide foil a supply of oxygen is allowed into the vacuum furnace to avoid dissociation of the oxide. The foil thickness is generally between 0.002 inch and 0.005 inch but may be <0.001 inch.  Apparatus for producing the foil comprises a vacuum chamber 51, a vapour source 61 heated by resistance, induction or electron beam bombardment, a substrate 63 in the form of an endless belt which moves above source 61 at a controlled rate, a source of wetting agent 73, a stripping device 67 to peel the foil off the substrate and a coiler 71 for the finished foil.  The material to be evaporated may be fed continuously to the source 61 from a coil 62.

Patent GB-371903-A (GB)
Title: Improvements in or relating to gun mountings
IPC: F41A27/22
Filed: 1930-10-29
Abstract: 371,903. Gun mountings. VICKERS - ARMSTRONGS, Ltd. and LEE, H. W., Vickers House, Broadway, Westminster, London. Oct. 29, 1930, No. 32514. [Class 92 (i).] The correction to be applied to the angle of deflection or training to compensate for inclined trunnion axis is superposed on the normal training movement imparted to the gun mounting by the training handwheel or motor. The correction, which is a product of two functions, one depending on the angle of inclination of the trunnions and the other on the angle of gun elevation is determined by mechanism, as described in Specification 154,944, [Class 92 (ii), Ordnance &c.], which is shown to the right of the Figure turned into the plane of the paper for clearness. The correction is applied to a link F moving about a pivot Fl by a pin G<x> engaging a slot in the link, the pin being adjusted on a sector E by a screw G<1> to suit the gun elevation, and the sector being maintained vertical by turning it on a pivot on a bracket B<1x> with the aid of a hand-wheel E<1> and spirit level e. By turning a hand-gear D<4> until the movement of a dial mark d<5> registers with a pointer F4 moved by gearing on the link F, the correction is applied to planetary member D of a differential-gear one side wheel of which is driven by the training handwheel b<4x> whilst the other side-wheel trains the gun through a worm-gear b<3>, pinion b<1>, and rack b. The Figure shows a similar differentialgear for combining with the normal elevation imparted by a hand-wheel a the correction for the inclination of the training axis in the vertical plane of the gun applied by a handwheel C<1> with the aid of a level (c<5>. The corrected elevation thus obtained is conveyed to the screw G<1> by a shaft g<2>, which drives a pinion g<9> on the screw through a differentialgear (not shown). An alternative arrangement is described in which the hand-wheels E<1>, b<4x>, C<1>, a, are replaced by hydraulic motors controlled by slide valves.

Abstract: 446,299. Automatic regulation of wire tension or of temperature. KINGSWAY RADIO, Ltd., 3, Dane Street, High Holborn, and OMBERAIN, G. L. D', 27, Gledhow Gardens, South Kensington, both in London. Nov. 13, 1934, Nos. 32698 and 33757. [Class 38 (iv)] [See also Group XXXVII] Windings 4, 5 in the respective conductors normally produce balanced, opposing fluxes in the core 6, but with a predetermined unbalance, a secondary 7 impresses on the grid 12g of a gas discharge valve a voltage which causes the valve to strike and energize a control device 13, 14. For regulating the tension exerted on a wire in wire-drawing apparatus, the wire supports a pulley in such a way that the vertical position of the pulley depends on the tension. The pulley supports a pair of plungers so arranged that one is normally suspended in the top of a solenoid and the other is normally suspended in the bottom of another solenoid, the solenoids being connected across windings such as 4, 5. A change in wire-tension causes the plungers to rise or fall and upset the balance so as to energize one or other of two coils such as 7 and operate one of two valves. According as to which valve is operated, a resistance is inserted in, or removed from, the shunt field of the motor controlling the wire-drawing, operation of the valve being repeated until the condition is corrected. A like arrangement may be employed for regulating furnacetemperature, the solenoids being replaced by a pyrometer and balancing resistance. The coil as 7 and valve control the amount of resistance in the furnace supply.

Title: Improvements in or relating to the treatment of textile materials
IPC: D06M15/17
Filed: 1932-11-21
Abstract: Filaments, threads, fabrics, films and like materials consisting of or comprising cellulose acetate or other cellulose ester or ether are subjected to the action of hot aqueous media or moist steam in the presence of a terpene.  The treatment reduces the lustre of the materials.  Pine oil, turpentine oil, limonene, sylvestrene, pinene, camphene, dipentene, camphor, menthol, borneol, terpineol, terpin, or bornyl acetate, may be used.  The terpene may be dispersed in the hot aqueous media by virtue of the soap content thereof or by dispersing agents such as turkey red oil or other sulphonated soaps or oils. The delustring bath may contain soda ash or caustic soda, Treatment may be effected in a winch machine, or by dipping, or on a jig, the material passing repeatedly through a bath in open width, or by impregnation with concentrated aqueous dispersions of the terpene followed by immersion of the materials in a bath of hot water or other aqueous medium.  Local impregnation may be effected by means of engraved or embossed rollers.  If desired, the material may be printed with resists, and the nonresisted portions may then be delustred.  The materials may also be treated to improve the feel, and reduce the tendency in fabrics towards slipping or laddering of the threads.  In an example, cellulose acetate woven fabric is scoured and then suspended in hot soap solution containing pine oil. It is then rinsed and dried.  In another example, cellulose acetate fabric is treated on a jigger containing a boiling solution of soap, soda, and pine oil.  Specification 165,164, [Class 2 (ii)], is referred to.
