Title: Improvements in or relating to machines for cutting shapes from sheet material
Inventor: COLLINSON FREDERICK BAKER
IPC: C14B5/00
Filed: 1950-03-02
Abstract: 702,324. Endless conveyers. COLLINSON'S PATENTS, Ltd. May 30, 1951 [March 2, 1950; July 26, 1950], Nos. 5262/50 and 18635/50. Class 78 (1) [Also in Groups VIII and XXIV] A machine for cutting shapes from sheet material, e.g. soles for boots and shoes from leather, comprises a movable multiple pattern of knives 10 on which the sheet material is placed so as to be traversed against a pressure roller 14, a device in each pattern for ejecting the cut shape therefrom, and a member 18 located over the path of movement of the pattern of knives for picking up the ejected shapes during movement of the knife pattern and conveying them away from the machine. The knives 10 are formed of longitudinal and transverse elements 11, 12 and positioned on a table 13 which is moved under the pressure roller 14. As the cut shapes are ejected from the patterns they are fed over the member 18, which is in the form of a ramp 18, to a wiper 19 consisting of flexible blades on a driven shaft; the shapes are thereby flung on to a conveyer 20 which feeds them to the centre of a rotary sorting table 21. The device for ejecting the cut shapes from the knife pattern consists of a pivoted lever 16 so arranged in each pattern section as shown in Fig. 6 that during passage through the machine its rear arm is depressed by the roller and the consequent rising of its forward arm ejects a shape. A bar 18a limits the upward movement of the ejected shape, and a guide 18b guides the shape to the ramp 18. Alternatively, each ejector may consist of a pivoted lever 30, Fig. 8 the effective end 31 of which is forked and urged upwardly by springs 29 ; the lower edge of the ramp 18 in this case is in the form of a comb, and a further spring- urged ejector 30a may be mounted between the fork.

Title: Improvements relating to starting switches for electric discharge devices
IPC: H05B41/06
Filed: 1943-04-02
Abstract: 565,302. Supply systems for discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd. April 2, 1943, No. 5284. Convention date, April 4, 1942. [Class 38 (iv)] [Also in Group XXXVII] A thermal switch for starting discharge lamps is constructed to cease to act after a certain number of unsuccessful attempts and to de-energize the circuit of the starting switch so that a manual operation is necessary before the switch can again function. The Figure shows the circuit including the discharge lamp 30 with electrodes 31. The thermal switch 6 and lock-out switch 20, 21 are shown apart, but are mounted on opposite sides of an insulating partition in the switch enclosure. Spaced contacts 11, 16 are alternatively engaged by a double contact 10 on the end of reversely mounted bimetallic strips 7, 8 welded together at 9. On switching on, a heating current through the electrodes 31 passes through the strips 7, 8, contacts 10, 11 and heater 14 near the lower strip 8 and also through another bimetal strip 21, the bent-over end of which retains contact with a spring 20, a high resistance heater 22 being in circuit as shown. On 7, 8 heating up contacts 10, 16 engage, a current surge passing through the electrodes and also through heater 22. Cooling of the strips 7, 8 then breaks the circuit and the lamp should start. If it fails to start, successive attempts result in the two-part bimetal floating between contact 11 and the mid-space, without making contact with 16. Moreover, sufficient heat by this time from heater 22 causes strip 21 to bend away and release spring 20, thereby opening the circuit of the starting switch. A push-button is provided to return spring 20 into engagement with strip 21 on cooling.

Abstract: 163,144. British Thomson - Houston Co., Ltd., (General Electric Co.). Feb. 23, 1920. Combined-flow type; oppositely-running rotor type; cooling parts; balancing moving parts.- 'Relates to turbines of the oppositely-running rotor type having a radial-flow blade system mounted on inner elements and an axial-flow blade system mounted on wheels attached to the inner elements, and consists in causing a flow of comparatively cool steam over the wheels to prevent un- .due heating and to maintain them at a substantially constant temperature. The Figure shows the left-hand side of a turbine of this type in which the inner rotating elements comprise a number of stages 5, 10, 13 connected toegther by expansion rings, the wheel 17 that carries the axial flow blading being secured to the intermediate stage by an expansion ring 16 provided with spaced openings 50. An annular wall 22 fixed to the casing directs the steam from the stage 13 to the axial-flow nozzles 21. The wheel 17 is provided with a large bore in which is situated an inner portion of a balancing and packing device comprising annular discs 35, 36 secured by expansion rings to the inner rotating element 5 and the wall of the steam chamber, and interleaving packing rings 39. Similar discs 40, 41 are situated at the side of the wheel 17, the disc 40 being connected to the disc 35 by a long expansion ring 43. Attached to the wheel is a ring 46 closely surrounding the peripheries of the discs 40, 41 so shaped that high-pressure steam leaking through the packing creates a suction in the annular space 47 and draws low-pressure steam from the space between the nozzles 21 and the axial-flow blades 18 down the inner surface of the wheel through the openings 50 in the ring 16 along the bore and up along the outer surface of the wheel to the ring 46. This steam is at the lowest temperature and thus cools the wheel, which is maintained at a substantially uniform temperature. Guards 48, 49 on the disc 40 and ring 43 shield the wheel from the high-temperature steam leaking through the packing.

Title: Improvements in and relating to the preparation of rubber derivatives or resins
IPC: C08C19/00
Filed: 1940-07-26
Abstract: 541,167. Cellulose and rubber compounds. BRITISH RUBBER PRODUCERS RESEARCH ASSOCIATION, and FARMER. E. H. July 26, 1940, Nos. 5611/41 (divided out of 535,889) and 9561/41. [Class 2 (ii)] Compounds of rubber with cellulose esters or ethers and maleic anhydride are obtained by heating the ingredients together, preferably in presence of a peroxide catalyst. If desired a rubber-maleic anhydride may be first obtained and this compound may then be heated with a cellulose ester or ether. Cellulose acetate, nitrate, or other ester, or ethyl or benzyl cellulose or other ether may be used. In an example, crepe rubber, maleic anhydride, ethyl cellulose, and benzoyl peroxide are dissolved in xylene, placed on a steam bath, and then heated under reflux at 150-160‹ C. A product is obtained which is completely soluble in ethyl alcohol, acetone, ether, and benzene, but insoluble in petroleum ether. The product may be plasticized, e.g. by milling with dibutyl phthalate or " Arochlor." Other examples describe the production of products from the same ingredients but in varying proportions. When the proportion of rubber is greater than that of the ethyl cellulose, the product is insoluble in ethyl alcohol. In another example, a solution of cellulose acetate, rubber, maleic anhydride, and benzoyl peroxide in tetrachlorethane is heated at 146‹ C. The solvent is removed and the residue is dissolved in acetone and reprecipitated with alcohol. In another example, a solution of cellulose nitrate, rubber, and maleic anhydride in amyl acetate is heated to 150‹ C. The product obtained is soluble in alcohol and acetone but not in petroleum ether. The rubber may be used in the form of crepe, smoked sheet, or natural, preserved, or synthetic latex. The products may be used for making transparent wrappings or bottle caps, or for other purposes. Specifications 507,996 and 535,889 are referred to.
Patent GB-803908-A (GB)
Title: Process for the production of aluminium powder
IPC: B22F1/145
Filed: 1957-02-19
Abstract: Aluminium powder is made by atomizing freely-falling molten aluminium in a closed chamber using an ultrasonic jet or jets of steam, at 3 to 15 atmospheres gauge pressure, as an atomizing medium.  The steam outlet is arranged concentrically with the stream of molten aluminium and is spaced from the point of atomization to prevent interference by metal particles.  Water is sprayed into the chamber to condense the steam and to reduce the temperature of the aluminium slurry to below 100 DEG C. prior to subsequent oxidation to produce a powder containing 6 per cent-12 per cent aluminium oxide, having a bulk density of between 0.7 and 0.8 gms./cc. and a lubricant content of less than 0.3 per cent. The oxidized powder may be used to make sintered bodies having a high tensile strength and hardness even at high temperatures. Physical properties of such bodies are given in the Specification
