Title: Improvements relating to the moulding of articles of microcellular rubber and other elastomeric substances
Inventor: WEBB CHARLES ERNEST
IPC: B29D35/06
Filed: 1958-12-08
Abstract: 940,970. Moulding microcellular rubber soles on to footwear uppers. ENGINEERING Ltd. Dec. 8, 1959 [Dec. 8, 1958], No. 39491/58. Heading B5A. A microcellular rubber sole is moulded and simultaneously vulcanized directly on to the underside of a shoe upper by subjecting a suitable rubber mix while enclosed in a sole moulding cavity to externally applied pressure and to unidirectional effective or differential heating (as defined below), and while maintaining said pressure and heating, increasing unidirectionally the volumetric capacity of the moulding cavity by a predetermined regulated amount, the rate of increase being correlated to the penetration of the effective or differential heating and to the desired cell structure. " Effective heating " means heating applied from one side of the mould by means of which vulcanization is effected and the blowing agent employed is activated; it does not preclude, however, heating applied from another side of the mould (for example, from a heated last) which is insufficient to initiate vulcanizing and blowing, and hence the expression " differential heating." By way of example, using a machine as is described in Specification 897,587 with appropriate contouring of the cam 80, a sole is provided on a shoe upper having dense skins of fine pores at the wearing surface and on the face which is attached to the insole and having an intermediate layer with larger pores. Full fluid pressure (approx. 900 p.s.i. hydraulic pressure equal to approx. 450 p.s.i. mould pressure) was applied for the first and last minutes of a 10 minute working cycle and the sole mould was dropped a total of 0.132 inch, commencing with 0.006 inch in the second minute, which drop was increased uniformly by 0.003 inch/min. until the ninth minute. The heating in this case was differential, a last heated to 100‹ to 105‹ C. being used, the sole mould temperature being 150‹ C. and the side mould temperature 148‹ C. The correlation of the varying factors involved, such as effective or differential heating temperature, full pressure applied (and duration of application), nature of rubber mix used, and the rate and uniformity or variableness of the increase in mould cavity capacity are in general readily determined by preliminary tests. In order to obtain microcells of uniform size, it is found that the rate of increase of mould cavity capacity (usually governed by sole mould withdrawal) must be equal to the heat front travel resulting from unidirectional heating, and on the basis of this correlation variable density microcellular masses are readily obtained.

Abstract: 829,745. Automatic temperature control systems. KELVIN & HUGHES Ltd. March 31, 1958 [Dec. 31, 1956], No. 39602/56. Class 38 (4). [Also in Group XII] In a furnace, the temperature in a flue 12 or of a back-wall 19 is maintained at an optimum value for a given fuel supply rate by adjustment of a damper 37 in a smoke-stack 14. The e.m.f. of a thermocouple 18 in the flue or of a thermocouple 17 contacting the back-wall is fed to a temperature controller 21 with a pointer 23 indicating temperature and a control pointer 22 positioned by gearing 28-30 driven by a device 26 responding to the rate of fuel supply by a mechanical stoker 25 to a grate 10. The output signal from the temperature controller is dependent on the position of the pointer 23 relative to the control pointer 22 and controls a damper-driving motor 36 through an interlock unit 33. The operation of a smoke-density warning device 40 through the interlock device opens the damper. With forced air supply to the furnace through a duct 46, an additional or alternative temperature controlled damper may be fitted. The controller is adjusted for change in the burning properties of the fuel by a manual device 43.

Abstract: 1,146,727. Incinerators. ALLIED METALS Ltd. 13 Nov., 1967 [7 Sept., 1966], No. 40068/66. Heading F4W. An incinerator comprises a refractory outer casing 1, an aluminium coated steel sheet inner casing 2, an electrically heated combustion basket suspended in the inner casing 2, an outwardly opening hopper 10, a safety shield (22, Fig. 2) co-operating with the hopper, and mechanism for opening and closing the hopper and automatically actuating the safety shield. The mechanism 11 includes a foot pedal 12 carried by a first arm 13 pivotably connected by a link 16 to one limb of a cranked arm 18, the other limb of which is pivotably connected to the hopper 10. A finger 20 located at the end of the one limb co-operates with an arm 21 for actuating the shield, which finger 20 can pivot in one direction but not in the reverse direction about the longitudinal axis of the one limb that carries it. When the incinerator is not in use the shield is in the vertical closed position, and to open the hopper it is necessary to depress the pedal 12 which causes the finger 20 to move and pivot past the arm 21 leaving the shield in the closed position with pins (23) on the hopper preventing the shield being moved. Upon release of the pedal, the hopper closes and since the finger 20 is not free to pivot in the direction necessary to clear the arm 21 it causes the said arm to pivot clockwise so that the safety shield swings inwardly and the materials placed in the hopper can thus fall into the combustion basket. Towards the end of the closing movement of the loading hopper 10 the finger 20 moves clear of the arm 21 so that as the hopper 10 finally closes, the shield returns to the position in which it closes the aperture. Operation of the mechanism 11 is also arranged to operate a trip lever 25 of a clock switching mechanism of the incinerator to cause the heating elements in the combustion chamber to be energized for a predetermined time.
