Filed: 1942-01-07
Abstract: 568,660. Making heat exchangers. COLTMAN, J. L., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Jan. 7, 1942, No. 240. [Classes 83 (ii) and 83 (iv)] Brazing.-The elements of heat exchangers comprising a matrix of thin-walled tubular or plate-like elements of copper or copper alloy, nickel or nickel alloy, or of a base metal such as steel or ferrous alloy coated with the abovenamed metals or alloys, are brazed together by interposing between the surfaces a thin film of an alloy of copper with tin comprising 60-95 per cent of copper and 40-50 per cent of tin, with or without up to 5 per cent of zinc, the alloy having a melting point below that of the elements or surfaces thereof, and heating in an inert atmosphere to a temperature between 700‹ C. and the melting point of the surface parts of the elements, which is sufficient to form a brazed joint. Heating may be effected so as either to melt the alloy film or to promote interdiffusion thereof. Where the surface preponderates in copper, the film may contain any proportion of copper within the above limits, but if the surfaces are of nickel or nickel alloy the film should contain a high proportion of copper. The alloy film may be applied by electrodeposition, hot-dipping, spraying, or as a dispersion in a liquid medium, or as a separate foil, and may be of thickness of the order of 0.0001-0.0003" for an element of the order of 0.005" in thickness. The atmosphere may comprise burnt coal gas or like hydrogen gases, hydrogen or cracked ammonia, a proportion of hydrogen being preferable. A plate-like type heat exchanger formed from steel strip 0.005" thick coated with 0.00025" of copper and then with a similar thickness of alloy of 60 per cent copper and 40 per cent tin, has the parts assembled in a jig and heated at 900-1000‹ C. for 10-20 minutes in a furnace with an atmosphere of burnt coal gas. The copper coating on the steel may be applied by rolling to prevent pin-holing. For a similar heat exchanger made from strips consisting of 80 per cent copper and 20 per cent nickel, a layer of 80/20 bronze powder formed into a paste with nitrocellulose solution is applied to the surfaces to give a film 0.00025" thick when molten and the elements are heated at 1000‹ C. under conditions as in the previous example. Specification 5232/10, [Class 83 (iv)], is referred to. According to the Provisional Specification, heating may be effected between 650‹ C. and the melting point of the surfaces.
Patent GB-228134-A (GB)
Title: Improvements in or relating to variable speed transmission mechanism
IPC: F16H9/24
Filed: 1925-01-05
Abstract: 228,134. Prentiss, J. W., (Assignee of Fannen, P. L.). Jan. 21, 1924, [Convention date]. Variable-speed and reversing gearing comprises an epicyclic pair consisting of expansible sprockets controllable in unison carried by a drum in turn controlled by a brake. A vehicle Hywheel 1, Fig. 2, is internally toothed so as to drive for forward speeds a pinion 42 fast upon a planetary spindle 10 which is longitudinally movable in a revoluble drum 8. Expansible planet and sun sprockets 9, 23 are mounted respectively about the spindle 10 and about a central driven shaft 3, which is movable longitudinally with respect to a tail shaft 5. The shafts 10, 3 are connected bv a lever 45 and are moved in unison to control the chain epicyclic pair through a link 50 from a pedal lever 46. A brake 51 which controls the speed at which the drum 8 may turn is controlled through a screw 52, Fig. 3, and linkage 54, 55, 56, 59 from a jointed foot-rest 48. As the link 59 is carried bodily with the pedal lever, it has a sliding connecton 61. A spring 62 tends to hold the parts as shown in Fig. 2 with the brake applied and the drum 8 stationary. Complete depression of the pedal 46 brings the pinion 42 into mesh with a central driving wheel 44, which effecfs reversed driving. Partial release of the pedal 46 causes a snug 63 on the link 59 to ride up a fixed cam 65 and rest in a notch 64. This is "neutral" configuration, the brake and pinion 42 being both disengaged. Further raising of the pedal allows the brake to grip, and thrusts the pinion 42 into mesh with the wheel 1 for forward driving. The chain gearing then functions. Further raising of the pedal moves the shafts 10, 3 to operate tne sprockets to raise the speed of the driven shaft. Finally, a snug 69 is carried over a fixed cam 70, which tilts the lever 56 and releases the drum 8, upon which' a spring-pressed clutch head 67 on the end of the shaft 3 engages a female clutch member 68 upon the wheel 1, yielding a top-speed solid drive. To prevent too sudden clutch engagement, the teeth of the members 67, 68 are inclined so as to tend to disengage. The brake is independently manipulated at any time by tilting the foot-rest 48. The sprockets 9, 23 are alike. Each comprises a pair of outer discs 13, 14 with radial slots 16, and a pair of inner sleeve-connected discs 20 with inclined slots 21, each set of crossed slots 16, 21 being threaded by one of the movable tread bars 11 upon which the transmission chain 35 rides. Each bar 11 has a pinion end meshing with a rack edge 17 upon one of the radial slots 16. Central helical connections 36, 38 and 39, 41 translate, the axial displacements of the shafts 10, 3 into relative rotary displacements of the crossed-slotted discs, and so vary the diameters. of the sprockets, in inverse ratio. A modification is described adapted for a bevel-gear transmission.

Title: Improvements in or relating to the manufacture of cellulosic films, filaments or the like
IPC: D01F2/10
Filed: 1939-01-05
Abstract: 523,566. Artificial filaments etc.; cellulose derivatives. BRITISH CELLOPHANE, Ltd. Jan. 5, 1939, No. 422. Convention date, Jan. 8, 1938. [Class 2 (ii)] Films, filaments, or like materials are obtained from a solution comprising in homogeneous admixture a normal viscose and an alkali soluble cellulose ether, the proportion of ether being not in excess of 25 per cent of the regeneratable cellulosic material. Normal viscose is defined as that prepared by a process in which the proportion of carbon bisulphide used for xanthation corresponds to from 27 to 40 per cent. of the cellulose and which contains about 7 per cent. of regeneratable cellulose material. Preferably the proportion of cellulose ether is not in excess of 5 per cent and it may be not in excess of 1 per cent of the regeneratable cellulosic material. The cellulose ether may be one which is directly soluble in dilute caustic alkali or which is soluble in such solution after subjecting the mixture to chilling. Methyl, ethyl, glycol, propylene glycol, isobutylene glycol. cyclohexene glycol, glyceryl glycolic acid, and hydroxy propionic acid, cellulose ethers may be used. The cellulose ether may be added to the cellulose xanthate and the mixture is then dissolved, or the xanthate may be dissolved in a solution of the cellulose ether in caustic alkali, or a solution of the ether may be added to viscose. Regeneration of the cellulose from the mixture may be effected by sulphuric acid baths containing sulphates. The sulphuric acid may be of plasticizing strength. The products have increased affinity for substantive or direct dyes as compared with products from viscose without the addition of cellulose ether. Films may be provided with moistureproof coatings, e.g., those having a nitrocellulose or ethyl cellulose basis. Films may be treated with salts such as potassium aluminium sulphate so as to obtain water-repellent effects. Products made from viscose containing cellulose glycollate have an increased affinity for basic dyes. Products containing cellulose oxy-acid ethers such as cellulose glycollic acid ether may be treated with copper, lead, aluminium, silver, or iron salts which react with the cellulose ether to form insoluble salts. Preparation of the cellulose ethers is described. Glycol cellulose is obtained by steeping sulphite cellulose in caustic soda solution, pressing, shredding, and treating with ethylene oxide vapour, until a water-soluble product is obtained. Cellulose glycollic acid is obtained by treating alkali cellulose with sodium chloroacetate. Cyclohexene glycol cellulose is obtained by treating alkali cellulose with cyclohexene oxide. Cellulose hydroxy propionic acid ether is obtained by treating alkali cellulose with sodium α-chloropropionate. The reaction product is allowed to age, then washed with hydrochloric acid, and with water. Specifications 283,109, [Class 2 (ii)], 389,534, 392,206, 469,007 and 470,747 are referred to.
