Title: Improvements in method of adhering butyl rubber to highly unsaturated rubbers
IPC: C08J5/12
Filed: 1958-02-26
Abstract: Butyl rubber is adhered to a highly unsaturated diolefine rubber by means of two interposed layers: a layer of brominated butyl rubber in contact with the butyl rubber and a layer of a vinylpyridine copolymer rubber in contact with the unsaturated rubber, the whole assembly being then vulcanized together.  The butyl rubber is a rubbery copolymer of an iso-olefine having from 4 to 8 carbon atoms, e.g. isobutylene, with from 0,5 to 10% of a polyolefine having from 4 to 18 carbon atoms, e.g. isoprene.  The unsaturated rubber is a polymer of not less than 25% of a diolefine, e.g. butadiene, with or without a copolymerisable monomer, e.g. styrene, and may be a natural rubber.  The brominated butyl rubber is a butyl rubber as above containing 0,5 to 10% of combined bromine.  The vinylpyridine rubber is a copolymer of from 55 to 15% of a vinylpyridine, e.g. 2-methyl-5-vinylpyridine or 4-vinylpyridine with 45 to 85% of a 1 : 3-diene having from 4-18 carbon atoms, e.g. butadiene.  Numerous other examples of monomers from which the several layers may be prepared are listed in the Specification.  All these layers are compounded for vulcanisation in known manner.  The layers may be fabricated and assembled in any conventional fashion, e.g. by calendering each layer separately and then superimposing or by skimcoating one layer on to another by multiple calendering.  The invention may be used to bond the layers of a pneumatic tyre. Specifications 718,768 and 733,138 are referred to.

Title: Improvements in or relating to Zinc-lead Pigments and the Method of Manufacturing the same.
IPC: C09C1/04
Filed: 1918-04-12
Abstract: 120,194. New Jersey Zinc Co., (Assignees of Singmaster, J. A., and Breyer, F. G.). Oct. 26, 1917, [Convention date]. Pigments.-Zinc-lead pigments are obtained by roasting oxidized ores of zinc and lead so as to volatilize the zinc and lead under oxidizing and sulphatizing conditions in order to sulphatize the lead without materially sulpbatizing the zinc oxide. In the production of pigment by a furnace of the known kind shown in Fig. 1, the desired sulphatizing and oxidizing effect is obtained by employing the requisite proportions of roasted and unroasted sulphide ores in the charge and forcing air through the charge by means of a blower 9 and pipes 10, 11. The fumes are quickly cooled by withdrawing them rapidly from the heated area by exhausting means connected to metal pipes 7 and drums 8, and conveyed to a bag-house. The required sulphatizing atmosphere may also be obtained by introducing sulphur trioxide or sulphur oxide and oxygen into the fumes from the furnace. Reference has been directed by the Comptroller to Specifications 7119/93 and 2789/07.

Title: Nuclear substituted dimethyl styrenes and their production
IPC: B01J21/20
Filed: 1945-03-15
Abstract: Mononuclear aromatic compounds including dimethyl styrene are produced by heating an asymmetric dixylyl ethane to at least 350 DEG C. in the presence of a finely - divided siliceous catalyst. 2,5-Dimethyl styrene, 2,4-, 2,6- or mixtures thereof, 2,3-, 3,4- or mixtures may be obtained by choice of the particular dixylyl ethane. Thus, 3,4- or 2,4-dimethyl styrene is obtained from the product of condensing acetaldehyde with o- or m-xylene respectively, using hydrogen fluoride as catalyst, as described in Specification 598,068. The preferred catalysts and reaction conditions are as described in Specification 592,867.  In examples: (1) di-(o-xylyl)-ethane and water vapour are passed over kaolin at 520 DEG  C., a pure dimethyl styrene being recovered from the product and shown to be the 3,4-isomer; (2) and (3) di-(m- or p - xylyl) - ethane with water vapour over hydrated aluminium silicate similarly yields 2,4- or 2,5-dimethyl styrene.  Reference has been directed by the Comptroller to Specifications 569,465 and 592,867.

Title: Improvements in or relating to apparatus suitable for use in operating on shoe uppers
IPC: A43D11/00
Filed: 1952-03-14
Abstract: 727,737. Shaping shoe uppers. BRITISH UNITED SHOE MACHINERY CO., Ltd., and JAMES, C. H. March 13, 1953 [March 14, 1952], No. 6631/52. Class 17 (1). Apparatus for shaping shoe uppers over forms therein comprises a two-part work support 35, 45 to support the upper and form bottom downwards, an end wiping device 13, means for causing the work support to rise relatively to the wiping device to cause the latter to wipe the upper toward the plane of the bottom of the form, and means to move a first part 45 of the work support relatively to the second part 35, after the upper has been shaped to the form and after the bottom of the form has reached a position more or less level with the underface of the wiping device, to cause the form and upper to rise further relatively to the wiping device. The first part 45 of the work support underlies a portion of the form, while the second part 35 underlies a marginal portion of the upper. The wiper plate 13 which is engaged in a guideway and located by a pin 21 is reversed for left- and right-handed shoes and changeable for shoes of other size or shape. A post 27 slidable in a sleeve 23 has a flange 29 to determine its lowermost position, is urged downwardly by a spring 67, and is movable upwardly by means of a pivoted lever 59 connected through 65 to an actuating treadle. A bore 31 in the post receives the stem 33 of member 35, the reduced lower end of the stem being surrounded by a compression spring 39 which abuts the shoulder 41 on the stem and the face 43 of the bore. The upper face of member 35 is recessed to receive the subsantially triangular plate member 45, so that the upper faces are substantially flush. A stem 49 on member 45 slides in a bearing 51 in parts 35, 33 of slightly greater length. A hole 53 in stem 49 is threaded to carry an adjusting screw 55 having a stem 57 which passes through a hole in stem 37 and protrudes therefrom but does not rest on face 43. In operation a shoe with upper and sock lining sewn together except at the toe, and the toe portions of upper and sock preferably cemented, is placed on the support and the treadle depressed to raise post 27 so that the wiper shapes the upper. When the upper margin is pressed against the underface of the wiper further movement of the treadle compresses spring 39 to apply clamping pressure, then as the post continues to rise face 43 engages stem 57 to raise member 45 an amount determined by the setting of screw 55, the upper being tensioned, and stretches if resilient, or otherwise slips between member 35 and the wiper. This pulls the upper tightly round the last and forms a crease in the upper margin which provides a guide for the stitching of the upper to the sock lining. Plate 45 may be tapered so as to incline upwardly toward the toe relatively to plate 35, so as to tilt the last so that a greater pull is exerted on the upper at the toe end than at the sides of the toe.

Title: Method of forging
IPC: B21K1/44
Filed: 1956-03-02
Abstract: 826,927. Forging screws and the like working at specified temperatures. HOLO-KROME SCREW CORPORATION. March 2, 1956 [June 15, 1955], No. 6682/56. Class 83 (4). Headed steel articles, such as screws, bolts, rivets, pins, are made by forging in a single machine steel blanks initially warmed to a temperature of 150-450‹ F. and not permitting the temperature to rise beyond 650‹ F. during forging. Steel wire stock 18 coated with a lubricant such as aluminium stearate or molybdenum disulphide suspended in oil, is fed in steps by rollers 12 through a high-frequency inductive heater 30 comprising a coil of copper tubing 36, Fig. 3 (not shown), supplied with high-frequency current through conductors 50, 52 from a transformer 64 or a converter or generator. A cooling liquid is circulated through the tubing and its housing 30. The warm stock then passes through a quill 72, of low heat conductive material such as polished stainless steel, to a cut-off knife 22 which severs it into blanks. These are transferred successively into a die 90, Fig. 8, where the end is extruded to a reduced diameter 96 and a preliminary head 98, Fig. 7 (not shown) is formed by a punch. A second punch 26 then completes the head 98 and forms a socket therein and the blank is then discharged by an ejector 94. Another embodiment is described, Figs. 10, 11 (not shown), for producing shorter socket-head screws without extruded shanks. The heading operation may alternatively be performed in three or more stages. Short blanks are preferably heated throughout their length but long blanks need only be headed in the region of the head portion and in this case specific examples of temperature gradients throughout the blank are given, Fig. 5 (not shown). The steel may be alloy steel, medium or high carbon steel and specific examples are given of the various temperatures and the time lag between heating, cut-off and heading. Specification 826,928, [Group XI], is referred to.

Abstract: 485,227. Strain gauges. UNITED ENGINEERING & FOUNDRY CO. March 6. 1937. No. 6696. Convention date. March 12, 1936. [Class 106 (ii)] A bar is connected at one end to the machine frame under test and the relative movement between the other end of the bar and the adjacent portion of the frame due to stress is measured by means provided, the bar being maintained at the same temperature as the frame. A bar 1 is connected at the ends to the structure, e.g. a mill housing by screws 7, 8 at points above and below the roll pass - line. A lateral notch 2 is provided at one end to accommodate an L- shaped lever 3 slit into two branches 5, 6 by the slot 4b each branch being incised at 4, 4a to reduce the cross section and to facilitate bending. The bolt 7 is inserted through an opening with plenty of clearance for the head in the limb 5. Upon the arm 3 rests the feeler 13 of a dial gauge 14. When the frame A stretches owing to work passing through the rolls, the bar 1 which is of the same material or of material with the same coefficient of expansion, exerts a force as it were at 4c causing the arm 3 to tilt as it were about a fulcrum 4d and this movement is transmitted to the gauge 14. The bar is placed in a slot 9 machined in the housing and enclosed by a cover plate 10. An oil bath 15 is provided as shown and a guard 16 fitted for the gauge 14. The indications of the dial gauge may be transmitted to a distance by providing the dial gauge with a circular rheostat over which works a light contact arm on the gauge spindle. By connecting these up in a Wheatstone bridge an indication is given on the electrical instrument.

Title: Process for the manufacture of sulphonic acid amide compounds
Filed: 1937-03-09
Abstract: 1 - Amino - 2 - alkoxy or aralkoxy - 5-alkylbenzene-4-sulphonamides are prepared by saponifying the corresponding 1-acylamino compounds, reducing the 1-azo compounds, or reacting the corresponding 1-halogen compounds with ammonia. The products possess therapeutic properties. The starting materials are prepared as follows: (a) in the case of acylamino compounds, by treating 1-acylamino-2-alkoxy or aralkoxy-5-alkylbenzenes with chlorsulphonic acid or its esters and reacting the resulting 4-sulphonic acid chlorides or esters with ammonia or primary or secondary amines; tertiary sulphonamides may also be obtained by treating the same initial materials with chlorsulphonic acid dialkylamides in the presence of aluminium chloride; (b) the azo compounds by diazotizing 1-amino-2-alkoxy or aralkoxy-5-alkylbenzenes, coupling with any suitable component, and treating the product first with chlorsulphonic acid and then with ammonia, a primary or secondary amine; (c) the halogen comopunds by reacting upon 1-halogen-2-alkoxy or aralkoxy-5-alkylbenzenes with chlorsulphonic acid and treating the resulting sulphochlorides with ammonia, a primary or secondary amine.  According to the examples, (1) 1-acetylamino-2-methoxy-5-methylbenzene is heated with chlorsulphonic acid to give the 4-sulphonic acid chloride which is then heated with aqueous ammonia and the product saponified with dilute hydrochloric acid to give 1-amino - 2 - methoxy - 5 - methylbenzene - 4-sulphonamide; the ammonia may be replaced by methylamine, dimethylamine, diethylamine, monobutylamine or hydroxyethylamine, whereby the corresponding substituted amides are formed; in a similar way, 1-amino-2-ethoxy-5-methylbenzene-4-sulphonamide and its monomethylamide, diethylamide and hydroxyethylamide are obtained; (2) 1-amino-2-ethoxy-5-methylbenzene is diazotized and coupled with 3-toluidine and the resulting 21 : 5-dimethyl-2-ethoxy-41-aminoazobenzene, after acetylation with acetic anhydride, heated first with chlorsulphonic acid and then with aqueous ammonia to introduce the 4-sulphonamide group; the product is then reduced with sodium hydrosulphite, whereby 1-amino-2-ethoxy-5-methylbenzene-4-sulphonamide is obtained; (3) 1-amino - 2 - methoxy - 5 - methylbenzene is diazotized and run into a solution of cuprous bromide in hydrobromic acid; the resulting 1 - bromo - 2 - methoxy - 5 - methylbenzene is heated first with chlorsulphonic acid and then with aqueous ammonia to give 1-bromo-2-methoxy - 5 - methylbenzene - 4 - sulphonamide which is finally heated for some hours with aqueous ammonia in an autoclave to replace the bromo group by amino; (4) 1-acetylamino - 2 - hydroxy - 5 - methylbenzene is warmed with 4-nitrobenzyl chloride and the 2-(41-nitrobenzyloxy)-compound so obtained then reacted in succession with chlorsulphonic acid and aqueous ammonia, yielding 1-amino-2 - (41 - nitrobenzyloxy) - 5 - methylbenzene-4-sulphonamide.

Title: Improvements in or relating to the production of water-sensitive non-fibrous sheet-like or film-like materials
IPC: C08J7/04
Filed: 1944-04-14
Abstract: The permanent shrinkage characteristic of water-sensitive, non-fibrous, sheet-like or film-like material containing not more than 10 per cent of moisture is reduced by applying thereto a surface coating comprising a water-insensitive film-forming substance, subjecting the coated material to the action of water to raise the moisture content of the base to an amount sufficient to release internal strains therein, removing the absorbed water while maintaining the material under little or no tension, and then removing the surface coating.  Permanent shrinkage is defined as non-recoverable shrinkage which occurs when the material is subjected to relatively low humidity conditions.  The coating substance, dissolved in a volatile solvent, may be applied to both sides of the sheets by a method such as dipping or spraying, solvent is evaporated by heat and the coated sheet is subjected to the action of liquid water or water vapour until it attains a moisture content such as 35 per cent and this moisture is removed, as by heated rolls, the material being at first allowed to shrink freely and it may then be subjected to slight tension until the moisture is reduced to 6 per cent.  The non-fibrous sheet-like material so treated may be lowly substituted cellulose ether such as methyl or ethyl cellulose or cellulose glycollic acid; lowly substituted cellulose ester such as the acetate, butyrate or aceto-butyrate; polyvinyl alcohol, or regenerated cellulose which may contain a softener such as glycerin. The coating material as described in several examples may include nitrocellulose, ethyl cellulose, chlorinated rubber, paraffin wax, dammar resin, modified rosin, dibutyl phthalate, zinc stearate, urea-formaldehyde isobutanol resin, paratoluene sulphonic acid, polyisobutylene, chlorinated paraffin, cyclised rubber and ester gum modified with maleic anhydride; solvents for this coating material comprise toluol, ethyl acetate, butyl acetate, ethyl alcohol, isobutyl alcohol and acetone.  Specifications 483,399, 522,643, 522,644, 535,378 and 538,280 and U.S.A.  Specification 2,017,866 are referred to.
