Title: Improved process for the treatment of regenerated cellulose textile materials and products resulting therefrom
IPC: D06M15/41
Filed: 1948-03-03
Abstract: Regenerated cellulose textile materials are impregnated with a polymethylol-phenol, obtained by condensation in an alkaline medium of p-tertiary amyl phenol and formaldehyde substantially in 1 : 2 molecular proportions, by adding the polymethylol-phenol to the spinning solution from which the textile materials are formed. The impregnated materials are then subjected to heat treatment. The polymethylol phenol solution, which is preferably first subjected to a slight condensation in the presence of lactic acid or acetic acid, may be added, as described in Specification 601,695, to the cellulosic solutions used for spinning the textile materials, which are then treated in the usual manner and subjected to thermal treatment, for example at about 110 DEG  to 120 DEG  C. for about 30 minutes.  Alternatively the polymethylol phenol solution may be applied to the yarn after spinning (see Group IV (c)).  In both cases the secondary swelling characteristics of the yarns are said to be improved and the tendency for the yarns to develop colour after bleaching, even with agents containing active chlorine, is said to be minimized.  Specifications 450,612, 456,552, 501,611, 601,694 and 601,696 also are referred to.ALSO:Regenerated cellulose textile materials are conditioned and their secondary swelling minimized by impregnating them with a polymethylphenol obtained by condensation in an alkaline medium p  of p-tertiaryamyl phenol and formaldehyde substantially in the molecular proportions of 1 mol. of the phenol to 2 mols. of the formaldehyde, and subjecting the impregnated materials to heat treatment.  The polymethylol phenol is preferably first subjected to a slight condensation in the presence of lactic or acetic acid. In an example, a thick bundle of filaments of regenerated cellulose, obtained in the usual way from viscose, is washed, desulphurized, bleached and impregnated with a solution containing 2 grams of laurylpyridinium sulphate and 1 gram of lactic acid per litre of water and also about 1.5 per cent by weight of the polymethylolphenol.  The bundle is then passed between rollers to squeeze out the excess liquid and thereafter passed over a series of drying rollers at 90 DEG  C. followed by a series of rollers at 130 DEG  C., giving a contact period of 10 minutes.  The bundle is then cut into sections 60 mm. in length and the staple is opened by beating, giving a woolly staple fibre having a secondary swelling of 50 per cent compared with about 100 per cent for a normal yarn.  The tendency for regenerated cellulose yarns to develop colour after bleaching, even with agents containing active chlorine, is said to be minimized by the treatment.  The impregnation of the textile materials with the polymethylol phenol may alternatively be effected by adding the latter to the spinning solution, (see Group IV (a)). Specifications 450,612, 456,552, 501,611, 601,694, 601,695 and 601,696 are referred to.

Title: Improvements in or relating to high pressure steam storage plant
IPC: F01K1/12
Filed: 1936-03-09
Abstract: 471,745. Power generating systems. GILLI, P. March 9, 1936, No. 6974. [Class , 122 (iii)] [Also in Group XIII] In plant for an electric power station comprising a steam boiler 101 supplying steam at 30 atmospheres to a high pressure turbine 104 the accumulator equipment consists of a charging and superheating accumulator 109 with an additional water space 110, and two groups of three accumulators in series 111-116. Charging is effected by water being withdrawn by a pump 126 into a jacket vaporizer 123 round the boiler steam pipe 103, the generated steam returning through pipe 129 to the first accumulator, and steam passing to the remainder through a valve pipe 119 when the pressure in accumulator 109 exceeds 110 atmospheres. Charging is regulated by a valve 27 which may open or close as the temperature in pipe 103 exceeds or falls below 400‹ C. Or the valve may increase or decrease the water supply to the vaporizer as the boiler pressure exceeds or drops below 30 atmospheres subject to the closure of the valve when the steam temperature falls below 380‹ C. In discharging, the storage steam is throttled down by a valve 135 to about the pressure of the main steam pipe which it enters after passage through superheater 121, valve 134 not being opened to discharge accumulator 109 until the storage pressure has dropped to 40 atmospheres. When the main steam pressure is reached the accumulators may discharge through a valve 138 into a low-pressure turbine 105 down to about two atmospheres. Charging is then effected up to 30 atmospheres by means of boiler steam admitted through valve 140. Replacement water is pumped from a condensate tank 107 either into the vaporizer 123 or directly into accumulator 109. An electric heater may be operated in parallel with vaporizer 123 to utilize cheap night current. A valve 142 may open to allow steam to blow off into the main steam pipe when the highest storage pressure is reached or the valve may be disposed in a pipe delivering water for vaporization in superheater 121 when water reaches maximum level in the accumulators 115, 116.

Title: Improved operating mechanism for combined airbreak power switch and earth switch
IPC: H01H31/00
Filed: 1943-05-10
Abstract: 565,553. Air-break switches ; actuation of switches ; indicators. ELECTRIC TRANSMISSION, Ltd., and GUMBRELL, E. C. May 10, 1943, No. 7383. [Class 38 (v)] A common handle is adapted to operate either, or in certain circumstances, both of two switches through the medium of a selector which is adapted to couple the handle to the selected switch only when both are in the " off " position. The selector is adjustable to enable both switches to be coupled to the handle for simultaneous operation, but normally the coupling means is such that only one switch can be engaged at a time, the other being locked against movement. The handle 20 is pivoted at 21 to the frame and at 19 to a pair of links 18 pivoted at 17 to spaced plates 13, 14 forming a clutch element 12. The latter is fast on a rotatable shaft 9 and carries spacers 15, the reduced ends 16 of which provide the dogs for selective engagement with holes 26 in a pair of plates 25 slidable and rotatable on shaft 9. The plates 25 are rigid with operating levers 27 connected to the switches proper, and project into slots in a selector bar 28, which is slidable in fixed brackets 29 by means of a handle 34 and cam 31, so as to engage the appropriate plate 25 with the clutch 12. This movement causes a hole or holes on the unselected lever 27, such as 40 on that of the power switch, to engage a fixed pin or pins, as 36, to lock the unselected switch. Further, since the dogs of the unselected switch move out of register with the holes 26 once the selected switch is moved from the " off " position, further operation of the selector bar 28 is prevented. The bar 28 is in two separate parts which can be reassembled with the slots 30 in such position that both plates 25 can be engaged by the clutch, a padlock and pin 51 preventing unauthorised adjustment. The handle itself can be locked in both positions behind a padlocked pin 42 passed through either of two upstanding brackets 44 on the frame. Plates 46 bearing appropriate legends and . carried on bar 28 uncover suitable markings on fixed plates 47 which are apertured at 48 to expose markings carried on shaft 9. Thus, in the position shown, the earth switch is locked " off," and the power switch is free and inthe " off " position.
Patent GB-646919-A (GB)
Title: Method for improving drying and semi-drying oils
Filed: 1947-03-18
Abstract: Drying and semi-drying oils are modified to increase the proportion of conjugated double bonds by heating them at a temperature below that at which polymerization occurs in the presence of a nickel or cobalt catalyst containing a small amount of chemically bound sulphur.  The temperature used varies from 170 DEG  to 220 DEG  C., preferably about 180 DEG  C., whereas the polymerizing or bodying temperature is generally higher than 270 DEG  C.  The modified oil may be subsequently bodied by further heating, for example to 285 DEG C., either after filtration or in presence of the catalyst.  In an example, refined linseed oil is heated with a catalyst consisting of 60 per cent nickel, 3 per cent sulphur, and 37 per cent kieselguhr, while carbon dioxide is conducted through it.  Alternatively, a cobalt catalyst containing 5 per cent sulphur without a carrier may be used.  Soya bean oil is similarly treated.  Catalytic agents.-A catalyst for the above process may be prepared by precipitating nickel carbonate in the presence of kieselguhr from a solution of the sulphate by sodium carbonate solution at 80 DEG  C.  The washed and filtered product is boiled with dilute soda solution, washed, boiled with nickel sulphate solution, filtered without washing, and the dried powder reduced in a hydrogen stream at about 500 DEG  C., whereby the nickel carbonate is reduced to nickel and the last-added nickel sulphate to nickel sulphide.  The catalyst is pyrophoric and must be kept in oil.  The preferred sulphur content is from 1-5 per cent, and other known carriers such as active carbon may be used.

Abstract: 453,480. Attaching heels to boots and shoes; adhesives. BRITISH UNITED SHOE MACHINERY CO., Ltd., Belgrave Road, Leicester. - (Assignees of Gordon, H. ; Columbus, Ohio, U.S.A.) March 9, 1935, No. 7404. Convention date, May 23,1934. [Class 17 (ii)] A wood or like one-piece heel for a shoe, which is shaped to enclose the shoe sole at its heelend, is permanently attached to the shoe by pyroxylin cement rather than by metallic fasteners. The seat of the shoe or the seat of the heel or, preferably both, is coated with cement which is activated immediately prior to the seating of the heel, and the parts are held in engagement under pressure until the cement has set. In one form, Fig. 4, the heel seat of an outsole 1 is formed with perforations 2 with lateral extensions 3 which become filled with cement to form pegs when the surface 4 is coated with adhesive. This cement is then activated and the heel is applied to the heel seat and held under pressure until the cement has set. Instead of coating the heel seat surfaces with cement, a blank 22, Fig. 20, of appropriate shape cut from a thin sheet of adhesive prepared by coating a sheet of glass with cement composition, in which bubbles of air have been entrapped by vigorous stirring, and removing it by a sharp-edged tool after it has set, may be activated, by dipping it into a solvent, and placed between the heel seat surfaces to be united. In a further form, Fig. 27, registering holes 41 may be formed in the inner and outer soles 35, 36 at the heel seat and these may be filled with adhesive to form pegs 42 which unite the soles together. Non- registering perforations 45 may be formed in the seat of the heel and become fitted with adhesive when the activated adhesive-coated heel seat surfaces are pressed together.
