Title: Improvements in or relating to means for converting reciprocating motion into rotarymotion and vice versa
IPC: F16H21/32
Filed: 1926-05-05
Abstract: 272,660. Lewis, T. H. May 5, 1926. Driving - gear. - In means for converting reciprocating into rotary motion and vice versa in which a bell-crank lever pivoted to a radius rod is interposed between a rotary crank and a connecting-rod coupled to an offset reciprocatory member such as an engine piston in a cylinder, the elements are so arranged that the crank rotates through more than 180 degrees during the stroke in one direction of the reciprocating member. The stroke may exceed the crank throw. The piston 3 is connected through a rod 4 to one arm 12 of a bellcrank pivoted at 11 to a rocker arm 9 mounted on a pivot 8 in the crank case 1, the other arm 13 of the bell-crank being connected to the crank pin 7. From the lower limit position shown, the piston reaches the top of its stroke before the crank 6, rotating clockwise, reaches the top centre A-B, the crank being carried over this position by the motion of the bell-crank which, during the early part of the downward stroke, is mainly a rocking movement about the pivot 11 with the rocker arm 9 substantially stationary.

Title: Improvements in or relating to the production of heteropolymeric resin compositions
IPC: C08G75/22
Filed: 1952-05-12
Abstract: <PICT:0717722/IV (a)/1> A resin of sulphur dioxide and an unsaturated organic compound is plasticized with an organic carbonyl compound wherein one of the bonds of the >C = O group is attached to carbon or hydrogen and the other bond is attached to oxygen, carbon or hydrogen.  The carbonyl compound must have a molecular weight between 135 and 1,000, a B.P. above 250 DEG F., must not have an aliphatic hydrocarbon group of more than five carbon atoms and is present in a ratio of 1 to 150 parts of the resin.  Organic carbonyl compounds specified are dimethyl and diethyl phthalates, methyl and ethyl phthalyl ethyl glycollates, butyl phthalyl butyl glycollate, ethyl-o-benzyl benzoate, diethyleneglycol dihydro abietate, camphor and others listed in example 1.  The heteropolymer may be derived from butene, dodecene, cycloolefins, styrene, butadiene, isoprene, cyclohexadiene, acetylenes, allyl alcohol, vinyl acetate, allyl ethyl ether, o-allylanisole, o-allylphenol, p-bromoallylbenzene, methyl undecylenate, undecylenyl alcohol, undecylenyl acid and mixtures of the above.  The compositions may be prepared by mixing in any suitable way but preferably by mixing an aqueous emulsion of the resin, of pH desirably 3 to 8, with an aqueous dispersion of the plasticizer.  In a preferred method the process is continuous and resin from a reactor 11 is purified in a stripper chamber 13, the pH is adjusted in chamber 17 and the latex is mixed with the plasticizer dispersion in chamber 21.  The emulsifier for the plasticizer dispersion may be selected from long chain alkyl sulphates and sulphonates, aryl and alkaryl sulphonates, fatty acid soaps, rosin acid soaps, condensation products of an alkyl phenol and ethylene oxide, dodecylamine hydrochloride and heptadecylamine-epichlorhydrin. The examples illustrate 1-butene-sulphur dioxide resin compositions prepared by various methods and example XV describes the coagulation of a plasticized latex by means of sodium chloride solution.

Title: Temperature control of air supply systems
IPC: F24F11/08
Filed: 1951-05-23
Abstract: 696,712. Ventilating aircraft and other enclosures. SHAW, G. E. May 23. 1951 [June 22, 1950], No. 12055/51. Class 137 In a ventilating system, especially for an aircraft, a compressor feeds air to a choke valve which can be positioned to throttle the compressor outlet duct and cause the air to become heated by the additional compression, the valve also serving to apportion the flow of air between two ducts, one of which contains a cooler whilst the other forms a bypass which joins the outlet duct from the cooler to form a single duct leading to the space to be ventilated. In the apparatus shown, a compressor 10 is connected by a duct 12 to a combined selector and choke valve 11, which has two outlet ducts 13 and 14, the former containing a refrigerator unit 17, the ducts combining at 15 into a duct 16 leading to the aircraft cabin &c. The valve 11, Fig. 2, comprises a cylinder 19 in which pivots a shutter 22 which can be moved from a position wherein it nearly covers the inlet port 24 to one wherein it covers the outlet 26 into the duct 14. In operation, with the shutter 22 in the " neutral" position shown, air from the compressor passes to the carbin almost wholly via duct 14 since the unit 17 in duct 13 presents a comparatively large resistance to the flow of air therethrough. If the air temperature rises above the level set on a thermostat 27 mounted in the duct 16, a reversible motor 28 moves the shutter to close the duct 14 thus diverting more air through the cooler 17. If the temperature falls below the required level, the shutter is moved to close off the inlet duct 12 and so produce more heating of the air by additional compression.

Abstract: 910,719. Shock absorbers. WOODHEADMONROE Ltd. Feb. 8, 1961 [April 8. 1960], No. 12564/60. Class 108(3). An hydraulic, lever-type, shock absorber of the kind comprising a casing 10 accommodating two pistons 13, 14 slidable, in opposing senses, one in each of two parallel cylinders 11, 12 which, in the normal operative position of the shock absorber are disposed one above the other with their longitudinal axes substantially horizontal, is characterised in that the uppermost rebound cylinder 11 is larger than the compression cylinder 12 so that the former is capable of developing a greater resistance than the latter while still working at the same unit pressure. As shown in Figs. 1, 2, the pistons 13, 14 are coupled respectively by connecting rods 15, 16 to a common rocker plate assembly 17 splined to a horizontal spindle 18 which projects outwardly from the casing 10 for connection to the two ends of a wishbone suspension arm 19. Each piston 13, 14 incorporates a resistance valve mechanism comprising a transfer valve 22, which is urged by a disc-type spring 25 on to a seating in an annular recess 21 provided in the outer face of the respective piston, and which has a stem 23 which extends rearwardly through a bore 20 communicating, at one end, with the recess 21 and, at the other end, with the cylinder space on the interior side of the respective piston.

Abstract: 660,265. Electromagnetic switches. MAGNETON, SPOLECNOST SR.o. April 25, 1946. No. 12568/46. [A Specification was laid open to inspection under Sec. 91 of the Acts, April 25, 1946.] Class 38 (v). [Also in Group XXXV] In a voltage regulator of the Tirrell type, for a D.C. generator, an auxiliary magnetic circuit, excited by the generator load current causes a falling output - voltage - load current characteristic beyond a specific value of load current and an early opening of an incorporated reverse current cut-out. As shown, the shunt field M of D.C. generator D, which charges battery B, is in series, across the generator, with the resistor R. Voltage regulation is achieved through the contact assembly 6 by which the field M or the resistor R is shortcircuited. The armature 1, which operates the centre moving contact of the assembly 6 connected to the common point of R and M, is supported by the insulated leaf spring 2 and caused to vibrate by the varying magnetisation of the core 4 and the yoke 3 under the influence of coil 5 subjected to the generator output voltage. The normally closed cut-out contacts 7 are in series with current winding 9 associated with core 8 forming an auxiliary magnetic circuit with air-gap 10 and the part 3a of the yoke 3. Beyond a given value of load current, saturation is effected of the part 3a by the flux generated by coil 9 thereby causing a part of this flux to flow through the armature 1 together with and in the same sense as that generated by coil 5, thus decreasing the regulated voltage progressively with rising load current. At low generator speeds, the battery B sends a reverse current through coil 9, the fluxes due to the coils 5, 9 in the part 3a are mutually resisting and saturation of 3a again takes place causing a rise of reluctance which reduces the main flux between core 4 and the armature 1. The mutual attraction between these members is lowered to a point at which the spring 2 causes armature 1 to open contacts 7.
