Title: Method and apparatus for the manufacture of pneumatic tyres
Inventor: MOUNTFORD DAVID
IPC: B29D30/20
Filed: 1969-04-19
Abstract: 1284735 Making pneumatic tyres DUNLOP HOLDINGS Ltd 15 April 1970 [19 April 1969] 20084/69 Heading B7C In an apparatus for making pneumatic tyres a cylindrical tube of reinforced elastomeric material having a circumference approximately equal to the circumference of the bead regions of a finished tyre is stretched to a circumference approximaately equal to circumference of the crown region of the finished tyre and successive strips of unstretched material are adhesively applied circumferentially to the external periphery of the tube, spaced apart from each other, the tube is severed in the spaces between successive strips and the regions of the tube not in contact with a strip are allowed to contract and return to their unstretched diameter. A sheet of porous elastomer 1 (e.g. reticulated flexible polyurethane foam) is unwound from a roller 2 and sprayed with adhesive from a gun 4 and brought into contact with parallel cord fabric 6 to form a laminated sheet which is passed through nip rollers 5 into driven rollers 8 which form the sheet into a tube, foam side innermost. The sheet 1 is a half-inch wider than the fabric 6 and the resultant unlaminated edge is coated with adhesive by a roller 9 and joined to the other edge to complete and seam the tube. Driven rollers 11 stretch the tube and further rollers 17 maintain it in the stretched condition while four superimposed breaker plies 12 are applied to it. The tube is then cut midway between two adjacent breakers to form a portion 13, the ends 14 of which are allowed to relax but that part in the vicinity of the breaker remains stretched. The portion is then placed on a collapsible tyre building machine, beads are positioned and turn-up effected, as at 15. The portion is subsequently placed in an inflatable mould 16 mounted on a centrifuge, polyurethane is applied and allowed to set. Non-porous elastomeric material may be used for the sheet 1 and if two or more plies are required in the carcass the breaker plies 12 are positioned further apart and the ends of the tube are turned up as far as the breaker layer or to the opposite bead wire; in this case foam sheet is applied to both sides of the cord fabric.

Abstract: 793,637. Coking heavy oils. ESSO RESEARCH & ENGINEERING CO. July 14, 1955 [July 23, 1954], No. 20410/55. Class 55 (1). In a process for coking a heavy oil containing sulphur the oil is contacted in a coking zone 1 with a fluidized bed of inert particles at a temperature between 850-1200‹ F., preferably between 900-1000‹ F., coke-covered particles are transferred by line 8 to a fluidized combustion zone 10 where they are heated to a temperature between 1050-1600‹ F., preferably 1100-1200‹ F., and the heated coke-covered particles are passed to a fluidized treating zone 21 where they are treated with a hot gas capable of removing sulphur from the coke on the inert particles, the thus treated particles being in part recycled by line 20 to the zone 1 and in part withdrawn through line 17. Hydrogen, e.g. in the form of hydroformer tail gas, is the preferred sulphur removing agent but steam, air, CO 2 , Co, Cl 2 , coke oven gas, producer gas, NH 3  and normally gaseous hydrocarbons such as methane can also be used. The residence time in the treating zone may be between 5 minutes and 10 hours, preferably between 10 and 120 minutes. In a modification the combustion and treating zones are contained in a single vessel, the combustion zone being superimposed on the treating zone. In a further modification the coking zone, the combustion zone and the treating zone are of the transfer line type, the coke-covered particles in the treating zone being contacted with C 2 , C 3  or C 4  hydrocarbon gas or mixtures thereof, e.g. ethane, to reduce the sulphur content of the coke. Temperatures of 1500‹ F. and 1300‹ F. are maintained at the inlet and outlet to the coking zone and the residence time in the zone is 0.5 second.

Abstract: 658,020. Water supplies. NEWTON, R. W. Aug. 5, 1949, No. 20455. [Class 68 (i)] When a water supply is obtained from a dirty source so that the filter 2 is likely to be choked, spray under pressure is directed on to the interior of the screened water-inlet 4 from a rotary spray device 10 in order to flush away the matter which is blocking the screened inlet of the filter. The supply of water under pressure is obtained from a pipe 9 connected to the water delivery pipe 8 on the outlet side of the pump 7 connected to the filter. A float operated control valve 11 is incorporated in the pipe which automatically brings the spray device into action when the entrance of water into the casing through the screened inlet is impeded to such an extent that the water in the casing falls below a predetermined level.

Abstract: 1370256 Door hinge ED SCHARWACHTER KG 3 May 1972 [10 May 1971] 20624/72 Heading E2F A door hinge comprising a first hinge part 7 with an eye 6 and a second hinge part having arms 1, 2 with eyes 5 at either side of and coaxial with the eye 6, has a hinge pin 4 with at least two radially extending protruberances which on insertion of the pin into the hinge cause distortion of the internal surface of the eyes. Thus the pin is prevented from radial displacement. The pin has radially extending corners 26 formed between an end surface 14 and an elongated slot 27, and, on the side of the pin diametrically opposite to the corners, radial hump-shaped parts 21, 23, the part 21 which is further forward in the direction of insertion of the pin being of less radial extent than the part 23. On insertion the part 21 produces a groove 25 in the softer material of the eyes 5, and is finally supported by outside surface 12 of the arm 2. The part 23 deepens the groove and the corners penetrate the material of the eye 5 in the arm 1. In a modification, Fig. 5, (not shown), the end surface 14 is provided with a number of radial protruberances (29) formed by the corners of elongated slots (30) one only of which extends the entire length of the pin. The hinge pin 4 may be provided with a coating of plastics material, at least in the region of the eye 6.

In a liquid fuel oil supply system for a plurality of burners 1 fed through branch lines 2 from a common supply line 4 via a distribution header 3, each line 2 has therein a balancing device 5 in the form of a positive displacement hydraulic motor unit, the motor units being mechanically coupled one to the other, e.g. by chain and sprocket gearing 6 so that each device is controlled by the remainder of the devices to ensure that the oil supply to each burner 1 is the same. Alternatively, by varying the ratio of the gearing 6 or using devices 5 of different capacities the liquid may be distributed through the lines 2 in unequal but specifically controlled quantities. The rate of flow through line 4 is controlled by a unit 7 which includes an orifice plate 8, a differential pressure cell 9 acting on a flow controller 10 and a flow controlled valve 11. Each unit 5 has on its discharge side a three-way valve 12 communicating with a by-pass line 13 so that if the flow of one burner is cut off, fuel still circulates through the unit 5 to allow operation of the remaining burners.
