Title: Copolymers of styrene and allyl fumarates and impregnating compositions containing such copolymers
IPC: C08F22/28
Filed: 1958-03-25
Abstract: Copolymers of 1 mol of styrene with 0,5-10 mols diallyl or dimethallyl fumarate are prepared in the presence of a peroxide catalyst and at least 10% by weight of the monomers of carbon tetrachloride.  The catalyst may be acetyl peroxide benzoyl peroxide or cumene hydroperoxide and polymerization is effected at 50-120 DEG C. for 3-100 hours.  The carbon tetrachloride acts as a solvent and modifier and in part as a comonomer, the product containing bound chlorine.  Impregnating compositions can be prepared from the above copolymer, if desired in solution as obtained from the process together with a polymerizable unsaturated polyester resin, a monomer containing polymerizable CH2 = C< groups and a polymerization catalyst.  The copolymer can also be isolated and dissolved in acetone.  The polyester resin may be formed from unsaturated acids such as maleic, fumaric or itaconic acids mixed if desired with phthalic, malonic, succinic, glutaric, sebacic, adipic, tetrachlorophthalic, endomethylene- and hexaochlorendomethylenetetrahydrophthalic acids esterified with ethylene, diethylene, propylene and dipropylene glycols to give an acid number of 35-40. Suitable commonomers are styrene, a -methyl-styrene, dichloro-styrene, diallyl phthalate carbonate, adipate or fumarate or triallyl cyanurate and are used in amounts of 25-35 parts with 75-65 parts of polyester.  The ratio of copolymer to polyester may be from 95:5 to 5:95 but is preferably about 80-20.  Conventional peroxidic catalysts are added in amounts of 0,1-10% by weight of the composition, e.g. benzoyl, acetyl, lauryl peroxides and cumene hydroperoxide; inhibitors such as hydroquinone, pyrogallol or p-tert-butyl catechol can also be added.  The compositions can be used to impregnate fibrous materials or to form laminates from paper (see Group VIII). Solvent is removed by drying at 25-75 DEG C. under vacuum or not.  The preimpregnated materials can be stored before lamination or moulding operations.

Title: An improved cigarette-making machine
IPC: A24C5/42
Filed: 1925-04-09
Abstract: 253,652. Price, W. J. April 9, 1925. Cigarette-making machines.-A hand lever 13 first actuates a compressing-device 1 for forming the tobacco into shape, and then moves a plunger 11 for forcing the tobacco into the paper tube, afterwards ejecting the cigarette. The hand lever 13, when moved from right to left, first actuates the movable side 7 of the compressing-device by means of a pin 16 engaging a slot 17 in a lever 14, which is pivoted at 15 and connected by a link 21b to toggles 21<a> working in fixed slots 20. After the tobacco is compressed, the pin 16 escapes from the slot 17, and a pin 25 working in a slot 24 in the hand lever moves a block 26 along a spindle 27 so as to take up lost motion between the block 26 and a U-shaped member 30 connected to the plunger 11. The plunger is then moved to the left to force the compressed tobacco into a paper tube held by a finger 12 upon a spigot tube 10. At the end of the plunger stroke, the finger 12 is moved aside to release the cigarette, which is then ejected. The upper edge of the compressor 7 co-operates with a fixed edge 9 to cut off projecting tobacco. In modifications, the lever 14 may be dispensed with and the link 21b coupled directly to the hand lever, which then becomes disengaged therefrom by means of a spring latch; or the link 21b may be connected to the common joint of a pair of toggle links, the free ends of which are pivoted to the frame and compressor 7 respectively.

Abstract: 622,879. Vehicle suspensions. KOLLER, E. April 10, 1947, No. 9596. Convention date, Aug. 1, 1946. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 11, 1947.] [Class 108 (ii)] In a vehicle suspension of the kind in which the axle of each wheel is connected to the frame by a link, the axle end of each link is connected to the frame by two rubber tension springs which act as supporting springs and extend in opposed relationship to one another with respect to the vertical to which, also, they are differently inclined. The axle is supported by a bracket 8 which is pivotally connected by a link 7 to a bracket 6 on a frame-member 5. A pin 9 passing transversely through the bracket 8 carries a number of superimposed rubber bands 16, which, at their other ends, are carried by a bracket 12 adjustably secured to a, frame-member 4. A second pin 10 in the bracket 8 carries a similar, but weaker, spring 17 which is supported at its other end by an adjustable carrier 13. The lines of action of the two springs are so inclined to one another that the ratio of the vertical component of the face of spring 16 to the horizontal component thereof is greater than the corresponding ratio for the spring 17. Further, at least at the position of maximum deflection, the component of the force of the spring 16 in the direction of deflection is greater than the component at right-angles thereto, while for the spring 17 the component in the direction of deflection is smaller than that at right-angles thereto.

Title: Electrical capacitor manufacture
IPC: H01G13/00
Filed: 1963-03-12
Abstract: 1,014,520. Capacitors. CORNING GLASS WORKS. March 12, 1963 [March 19, 1962], No. 9778/63. Heading H1M. A method of manufacturing capacitors consists of forming a capacitor stack from a plurality of thin glass strips 10, 14, 18 separated by thin metallic foils 12, 16 having leads 20 attached thereto disposed within glass covers 22, heating the stack to a temperature of about the softening point of the glass components so that adjacent components adhere, applying fluid pressure to the stack and maintaining the pressure until the stack is hermetically sealed and any air entrapped within the stack is compressed into small spherical bubbles reducing the temperature to below the softening point of the glass components and thereafter removing the pressure. The operation may be carried out by enclosing the capacitor assembly in a pallet designed to compress the capacitor to its required dimensions as soon as it has been heated to softening point, and containing this arrangement inside a pressure furnace into which gas at pressures between 750 p.s.i.g. and 1500 p.s.i.g. is pumped as soon as softening occurs. The effect of this manufacturing process is to reduce the size of air bubbles contained in the finished capacitor structure, thereby minimizing their effect on the capacitor performance.

Patent GB-358033-A (GB)
Title: Improvements in dyeing
IPC: C09B1/56
Filed: 1930-03-28
Abstract: Green or blueish-green shades are produced on cellulose ester or ether materials by the application to such materials of dihydroxydimercaptoanthraquinones in which the hydroxy and mercapto groups all occupy a -positions.  Thus there may be employed products obtained either by alkaline hydrosulphite reduction of Solway Emerald (prepared by the action of sodium sulphide on 1,5-dihydroxy - 4,8 - dinitroanthraquinone - 2,6 - disulphonic acid admixed with some 1,8-dihydroxy-4,5 - dinitroanthraquinone - 2,7 - disulphonic acid according to the process of Specification 20359/05, [Class 2, Acids and salts, Organic &c.]), or by the interaction of alkaline polysulphide and a dihydroxydihalogenanthraquinone (the hydroxy and halogen substituents all being in a -positions); the reduction of Solway Emerald appears to result in the elimination of sulphonic acid groups, while the polysulphide treatment in the second process results in replacement of halogen atoms by mercapto residues. The products may be applied by dyeing from aqueous suspension or solution with or without the addition of dispersing or solubilizing agents, as for example soluble oil or sulphite cellulose liquor, and they may also be used in printing or other processes.  In examples (1) Solway Emerald is treated in boiling aqueous solution with sodium hydrosulphite.  A 10 per cent aqueous paste of the product, which appears to contain one sulphuric acid group, is dispersed with soluble oil and used for dyeing green shades on cellulose acetate: (2) the alkaline hydrosulphite treatment of (1) is repeated to give a product free from sulphonic acid groups and which dyes cellulose acetate more readily: (3) 1,4-dichloro-5,8-dihydroxyanthraquinone is treated in aqueous methylated spirit with sodium polysulphide; the product dyes blueish-green shades.  The treatment with polysulphide of 1,5-dihydroxy-4,8-dichloro-(or dibromo)-anthraquinone and of the isomeric 1,8 : 4,5-compound and of 1,5-dihydroxy-2,4 : 6,8-tetrachloro-(or tetrabromo-)-anthraquinone to give similar products for the process is also referred to.

Abstract: 375,859. Escalators. BENNIE, Ltd., J. and BENNIE, J., 39, Victoria Street, London. April 2, 1931, No. 9974. [Class 78 (i).] In an escalator of the type in which a series of steps connected to driving chains are guided in an endless path by inner and outer rails engaged by pairs of inner and outer rollers on the steps, a driving motor 20 is connected by reduction gearing to a countershaft 16 which is connected by chain-and-sprocket gearing 14 to a main shaft 12 on which are secured two large driving sprocket wheels 11 engaging the step driving chains 10, the arrangement being such that the chain parts engaged by the sprockets are the parts through which extend the axles 42 carrying the outer rollers 31. The gearing 14 is provided in duplicate. Each step S is built up of plating and comprises a top plate composed of a metal bar 35, Fig. 7, and a wooden board 35a to which tread bars 36 are nailed, a curved riser, and two side webs 38. Bearings 39, 41 for the axles 40, 42 of the rollers 30, 31 are mounted in the side webs. Each step is strengthened by a cross-stay 43. The escalator works in unison with two flexible handrails 50 passing around pulleys 51 .. 56. The pulleys 51, 53 are driven by the shaft 12 through chain-and-sprocket gearing. The tension of each handrail is varied by adjusting the position of the pulley 56. Two independent brakes may be provided to bring the escalator and motor 20 to rest whenever an auxiliary control circuit, associated with the current supply to the motor, is interrupted. The brake 70, Fig. 1, is of the spring-actuated double block class and is applied to a drum on the shaft 12. The blocks have an operative connection with an auxiliary motor 72 which is operatively connected to the controller of the motor 20, the arrangement being such that when the motor 72 is switched on, the brake is released when the motor 20 is started. The brake 71 acts on a pulley constituting a coupling element in the shaft 19. The control circuit is interrupted when any driving chain breaks by the descent of pivoted arms 73, and on the attainment of excessive speed by a governor 76. A motor cut-out switch 78 becomes operative if the motor is subjected to excessive overload or is entered by moisture. This switch is releasable by an instantaneously acting electromagnetic device or a thermally retarded device.
