IPC: C08J5/02
Filed: 1928-05-19
Abstract: 321,913. Dunlop Rubber Co., Ltd., and Trobridge, G. W. May 19, 1928. Moulding by dipping.-Articles of rubber or similar material are manufactured by dipping a heated non-porous former into a concentrated or concentrated compounded aqueous dispersion of or containing rubber &c. only long enough for a substantially fluid layer to adhere to the former. The former is revolved to ensure even distribution and is then dried. The article may be partly dried and then stripped from the former to be finished in any known manner. Vulcanising agents, accelerators or filling agents may be incorporated with the dispersion; sulphur transformer oil and an accelerator being mentioned in the example given. Specification 285,844 is referred to.

IPC: B65G39/00
Filed: 1961-04-24
Abstract: 931,123. Conveying in heat treatment furnaces. C. MACGREGOR, and J. MACGREGOR, [trading as MACGREGOR BROS]. April 24, 1961, No. 14780/61. Class 51 (2). [Also in Group XXX] Elongated bars, Fig. 1, are progressed along rolls 14 driven from motor 31 and enter furnace 13 through aperture 15 and are hauled into position inside the furnace by rolls 16. The bars then pass on to walking beams 19, 20 and are then positioned on rolls 21 driven by motors 24. The rolls 21 then feed the bars out of the furnace at 22 for further treatment. Rolls 14 or 16, Fig. 3.-Roll 14 or 16 is formed with eccentrics 27 of which contiguous eccentrics are spaced radially by 180 degrees. The effect is that a bar W is moved sideways as it is fed forwards so as to give the bar a longitudinal translation and also a rotation, until finally it is fed on to the working beams 19, 20. In this way each bar is given a uniform treatment.

Patent GB-1502117-A (GB)
Title: Cabinet with temperature control device
IPC: H05B1/02
Filed: 1976-07-09
Abstract: 1502117 Temperature control apparatus C N HILLIER 9 July 1976 [11 April 1975] 14933/75 Heading H2H Apparatus for controlling the temperature of a heated or refrigerated cabinet comprises a switching device to control the ON-OFF periods of the current supply to the heater in the cabinet in dependence upon the temperature in the cabinet together with means for biasing the operation of the switching device in dependence upon the temperature of the ambient surroundings. A cabinet 11 of a heating or refrigerating device comprises a heating element 49 in series with two normally closed micro-switches 28, 29, the switches being carried on a member 17 rockable about a pin 9 by the opeating rods 19, 37 of temperature sensing elements 20, 38 respectively, the element 20 being responsive to the temperature in the cabinet 11 and the element 38 responsive to the ambient temperature, the member 17 being biased in a clockwise direction by a spring 18. Furthermore the element 38 is surrounded by a heating coil 41 which is connected in series with the switches 28, 29 and the heating element 49. As the cabinet 11 heats up the sensing element 20 operates, at a given temperature, to open the switch 28 thereby de-energizing the heating element 49 by virture of the rocking movement of the member 17. The cabinet 19 cools down and the action of the element 20 causes the switch 28 to reclose to cause further heating of the cabinet 11 and the cycle repeats with a decreasing ON-OFF ratio of the operation of the switch 20 until the temperature of the cabinet 11 stabilizes at a desired temperature. Variation of the ambient temperature causes the sensing element 38 to bias the position of the member 17 thereby varying the operational ratio of the switch 28. The switch 29 forms a safety precaution in the case of overheating of the cabinet 11. In a second embodiment the action of the switch 29 is assisted by means of an electromagnetically operated relay. The sensing elements operate by the differential expansion of the respective rods and the surrounding tubes.

Abstract: 845,209. Diaphragm pumps. PLENTY & SON Ltd. May 5, 1958 [May 13, 1957], No. 15132/57. Class 102(1). A metal diaphragm 18 is welded at 42 to the casing forming a pump chamber 24 provided with inlet and outlet valves 30, 32. The diaphragm is actuated hydraulically by a ram 14 operating in a labyrinth gland 34 and is supported by grids 46, 48 which prevent reverse bending, the diaphragm operating between two degrees of convexity. Several pumps are arranged in a common block 10 and the rams 14 are driven by a motor 20. The pump is intended for circulating in a nuclear power plant pure water which may become radio-active.

Title: Improvements in the stabilization of polyester fibres to ultra-violet light
IPC: D06P1/651
Filed: 1959-05-04
Abstract: Polyester fibres, which may be in the form of filament yarns, staple fibres or cloth made from such fibres, are stabilized against degradation by ultra-violet light by treating them with diethylene glycol having dissolved therein an ultra-violet light absorbing amount of a compound having the formula:-  <FORM:0867262/IV(c)/1> in which R represents hydrogen or an alkyl group of 1-5 carbon atoms and R1 represents an alkyl group of 1-5 carbon atoms, at a temperature of 340 DEG -365 DEG F., and then removing excess diethylene glycol solution from the fibres and rinsing them in water.  The solution may contain 0,5-3% by weight of the ultra-violet light absorbing compound and the fibres may be immersed therein for 5-15 seconds.  After rinsing and, if desired, soaping, the fibres may be dyed, the treatment protecting not only the fibre itself but also the dyes against ultra-violet degradation.  Example IV describes the treatment of polyethylene terephthalate fibres with 2, 21, 4-trihydroxy-41-methoxy benzophenone dissolved in diethylene glycol, followed by dyeing with 1-amino-4 anilinoanthraquinone. Specifications 706,151 and 786,762 are referred to.

The transfer layer may be in the form of stripes to record in 1 out of 10 or other code when a mark is made on a numeral or letter printed on a top sheet, or it may be in the form of different dot matrices delineating different characters. The transfer layer may be supported on a separate sheet between top and copy sheets or it may be directly attached to the back of the top sheet or attached to the top surface of a backing sheet so that recording is effected on the rear surface of the top sheet. The transfer layer may be a carbon, pressure-sensitive capsules containing a marking substance or a mixture of such capsules and capsules containing a solvent which releases the marking substance over the complete marking area. Alternatively, solvent capsules may be located between the top sheet and copy-producing areas to release the latter from the top sheet and render them adhesive so that they become attached to a copy sheet. The marking substance may be magnetic, conductive or differently coloured dyes. One or more clock tracks may be printed on the copy sheet.
