Abstract: 220,672. Bullock, H. W. Feb. 28, 1923. Two-stroke-cycle engines; driving-gear.-The pistons of two coaxial cylinders are rigidly connected to move together the drive to two cranks on the crank-shaft S being through outside connecting rods R working on a gudgeon G projecting through slots in the lower cylinder. The pistons are connected by a central rod R<1> passing through a partition separating the two pistons, or by outside coupling rods, the upper piston having a gudgeon similar to the lower. The lower cylinder projects into the crank case, which has side extensions to enclose the coupling and connecting rods. The adjacent ends of the cylinders act as pump chambers, the piston controlling the inlet and transfer ports; in one form the piston has a port cut in its length to control the transfer passage.
Patent GB-119667-A (GB)
Title: Improvements in and relating to Machine Guns.
Inventor: PIERCE VINTON ULRIC DAHLGREN
IPC: F41F1/08
Filed: 1917-04-26
Abstract: 119,667. Pierce, V. U. D. April 26, 1917. Machine guns.-Relates to multi-barrel machine guns fitted with mechanism for converging or diverging the barrels, and consists in providing flexible means connected with the triggers of all the barrels for operating them simultaneously in all positions. The invention also includes means for rotating the group of barrels round a central longitudinal axis, and for operating the converging and diverging mechanism whilst the barrels are rotating. Fig. 1 shows in plan four Lewis guns 25 mounted on trunnions 26 in a support 23 keyed to a shaft 22 which can be rotated in bearings on a frame 10 by spring motors 27 through chain-and-sprocket gearing 31. The frame 10 can be elevated by a shoulder piece 21, Fig. 9, on trunnions 14 in a pedestal 16 revoluble on ball bearings for training with respect to a fixed support 18. The spring motors are wound by handles 32, and the speed of each motor is controlled by a centrifugal governor 54 acting on a friction sleeve 55, the speed of rotation of the shaft 22 being controlled by a band brake 51 operated by a lever 53. The guns are arranged normally to diverge .so as to provide a zone of fire around the target, which zone may be contracted by moving the barrels until the projectiles are directed on to the target by moving the barrels into parallelism. A bell or other signal notifies the gunner when the barrels are parallel. By a further movement, the barrels may be made to converge so as to provide beyond their'point of intersection, a divergent zone. To effect these adjustments the barrels are, during rotation, rocked on the trunnions 26 by a forward movement of a handle 43 attached to a sleeve 33 sliding on the shaft 22 and connected to the stock of each gun by links 36. A short arm 45 forming an adjustable bell-crank lever with the link 36 is connected through a spring 46 to the trigger 47 of each gun so that, during forward movement of the sleeve 33, the gun triggers are held back to permit of continuous firing. In a modification, Fig. 9, the triggers are actuated independently of the sleeve 33 by a trigger 67 arranged on the handle block 65. This trigger, Fig. 11, operates to release a spring 68 which acts through links 73, 70 on a spring-controlled sleeve 60 which slides on the shaft 22 and actuates the gun triggers by cables 62 passing along each of the arms 36. The barrels may be supported, as shown in Fig. 19, in order to dispense with the front bar 12 of the frame 10 which obstructs the firing.

Title: Pressure-sensitive adhesive sheets and tapes
IPC: C09J7/50
Filed: 1961-02-17
Abstract: A method of rendering a flexible hydrophobic backing film of cellulose acetate-propionate or cellulose acetate-butyrate, to which pressure-sensitive film adhesives ordinarily adhere poorly, capable of forming firmly adherent bonds with a subsequently applied pressure-sensitive adhesive, includes the steps of preparing an aqueous emulsion of a polymeric alkyl acrylate, which is capable of forming a substantially tackfree film, and a rubbery material which is compatible with the pressure-sensitive adhesive which it is desired to employ, uniformly applying the emulsion on a major surface of the backing film, and heating the thus coated film, e.g. to a temperature of 170 DEG  F. (77 DEG  C.), for a time sufficient to evaporate the water and anchor the primer coating to the film.  A pressure-sensitive adhesive is applied over the primed film.  The alkyl acrylate polymer (which term includes alkyl methacrylate polymers) may be non-tacky and derived from an alcohol containing not more than four carbon atoms.  The aqueous emulsion may comprise polymers of alkyl acrylates or alkyl methacrylates, or copolymers thereof with vinyl acetate or chloride, acrylic or methacrylic acid, itaconic acid or maleic anhydride, and a soft, readily deformable rubber of the same type as that contained in the pressure-sensitive adhesive, the weight ratio of alkyl acrylate polymer to rubber in the primer layer being in the range of from 0,5 : 1 to 2 : 1.  The primer layer may comprise from at least 0,02, e.g. 0,2-10, parts by weight of an alkyl acrylate polymer derived from an alcohol containing not more than four carbon atoms and one part by weight of a soft readily deformable rubber, e.g. a normally tacky acrylate polymer which is compatible with the pressure-sensitive adhesive.  The pressure-sensitive adhesive sheet material is capable of being wound in roll form and unwound therefrom in normal use.  The rubbery material may be natural rubber, butadiene-styrene copolymer, polyisobutylene or butyl rubber.  The adhesive specified contains natural rubber and terpene resin.

Filed: 1937-03-03
Abstract: 493,348. Automatic control systems. LUCAS, Ltd., J., and LAIRD, J. A. March 3, 1937, Nos. 6292, 7282, and 30817. [Class 38 (iv)] Current strength; electromotive force.-A dynamo regulator of the constant voltage type comprises a carbon pile d in series with the field winding b, an electromagnet c acting on the pile through an armature e, which electromagnet is in series with the pile d and in series or in parallel with the field winding b, a further electromagnet g, h responsive to the current or voltage or both of the dynamo a being arranged to act on the pile d or its electromagnet c or both by means separate from the armature e. In Fig. 1, this means may comprise contacts j which introduce the resistance d into the field circuit to reduce field current when the dynamo voltage or current rises above a predetermined value. Alternatively contacts k may short circuit the coil c so as to increase the resistance of the pile or again, a combination of the two methods may be provided by contacts o, p, q. In a modification the coil c is shunted by a resistance and is controlled by series contacts operated by the electromagnet g, h. In a further modification the coil c is connected across the field winding in series with a resistance and the electromagnet g, h acts to close or open contacts in shunt with the coil or its series resistance respectively. In Fig. 4, the coil c is shunted by a subsidiary carbon pile i, having an intermediate armature controlled by the electromagnet g, h and connected to the field winding b, so as to byepass more or less of the current around the coil c to effect control of field current in response to the dynamo output. In a further arrangement, Fig. 5 (not shown), the coil c is connected in series in the field circuit on the side of the pile remote from the field coil and is controlled as in Fig. 1, an additional fixed resistance in series with the coil and in shunt with the pile and the field winding being provided to ensure the passage of a fixed basic current and the effective action of the electromagnet c over the whole of the working range. The contacts j, k &c., may be carbon contacts or elements which are always in contact, but have their resistance varied by pressure variations to effect the desired control. Alternatively the contacts j, k &c. may be replaced by subsidiary carbon piles. The first Provisional Specification discloses an arrangement in which the pile is short circuited by auxiliary contacts which are closed when the dynamo is at rest or the magnet insufficiently excited whereby a rapid building up of the generator voltage is effected. Specifications 3703/11, 133,724, 213,278, 278,846, and 292,521, [all in Class 38 (iv)], are referred to.

Title: Manufacture of unsaturated ethers of aminotriazine formaldehyde condensation products and oxidative drying compositions containing such ethers
IPC: C08G12/42
Filed: 1958-02-26
Abstract: 863,275. Unsaturated ethers of aminotriazineformaldehyde condensates. CIBA Ltd. Feb. 26, 1958 [March 1, 1957; Jan. 27, 1958], No. 6298/58. Class 2(5). 2-butene-1-ol ethers of aminotriazine-formaldehyde condensates contain at least one butenyl ether group per amino group are prepared by reacting a methylol-containing aminotriazineformaldehyde condensate or an ether thereof with a saturated alcohol having 1-4 carbon atoms with 2-butene-1-ol in presence of acid. Suitable aminotriazines are melamine, N-phenyl melamine, benzoguanamine, adipoguanamine, acetoguanamine, formoguanamine, ammeline, 2, 4-diamino-6-chloro-1-3-5-triazine. The products have air-drying properties when mixed with driers, e.g. cobalt naphthenate or cobalt-2- ethyl hexanate. At higher temperatures, iron, nickel, chromium, aluminium, calcium or zinc driers are also effective. Pre-polymerization, e.g. by blowing with air shortens the drying time. Addition of peroxides, e.g. benzoyl-, di-tertbutyl-, lauryl, or hydroxycyclohexylhydro-peroxide accelerates drying, or, used in conjunction with a metal drier causes polymerization. The products are useful additives to conventional compositions based on other binding agents, e.g. drying oils, styrenated oils, alkyd resins, cellulose derivatives, thermoplastic materials, e.g. polyvinyl acetate, polyvinyl acetal or polystyrene. The unsaturated ethers may also be used in conjunction with monomers polymerizable with peroxides, e.g. styrene, vinyl esters, acrylic acid esters, acrylonitrile or α, #-unsaturated polyesters. The butenyl ethers may be modified by reaction with alcohols, e.g. ethylene glycol, stearyl alcohol, myricyl alcohol, linoleyl alcohol, or partial ethers or esters of glycerol. In Examples (1) hexamethylol melamine was reacted with 2-butene-1-ol in presence of HCl. The product dissolved in toluene and mixed with cobalt naphthenate, and if desired with benzoyl peroxide gave an air-drying composition; (2) Tetramethylol benzoguanamine was etherified with 2-butene-1-ol. After-treatment at 130- 150‹C. in vacuo increased its viscosity; (3) The butenyl ether of Example 1 was esterified with soya fatty acid; (4) The product of Example 1 or 3 was mixed with a linseed oil, glycerol, phthalic acid alkyd resin, lead and cobalt naphthenates and solvents to give a lacquer; (5) A methylol melamine methyl ether was re-etherified with 2- butene-1-ol in presence of hypophosphorus acid; (6) The product of Example 5 was reacted with linseed oil fatty alcohol; (7) The ether product of Example 1 was reacted with linseed oil diglyceride and hypophosphorus acid; (8) The methylol compound of adipoguanamine is prepared and reacted with butenol and hydrochloric acid.
