Title: Valve
IPC: F15B13/04
Filed: 1966-11-29
Abstract: 1,120,698. Valves. NEW YORK AIR BRAKE CO. 29 Nov., 1966 [23 Feb., 1966], No. 53395/66. Heading F2V. [Also in Division F1] A valve plunger 11 which selectively connects the working chambers of a double-acting motor 22 with a supply pump 57 and a reservoir 21 is movable from the " neutral " position shown, in which motor chambers 14, 18 are isolated, to " raise " and " lower " positions, and is provided with a load drop check valve 48 and a coaxial valve 49 which serves to control the bias on valve 48. The plunger is also provided with a check valve 35 and a by-pass valve 38 which, when opened, directs return fluid from the exhausting lower chamber of the motor directly back into the working upper chamber to increase the rate of flow of fluid in the event of the load moving the piston 22a faster than the pump 57 can make up. With the plunger in the " raise " position (Fig. 2, not shown) the pump supplies fluid to the lower end of the cylinder via chamber 15, radial passages 45, valve 48, radial passages 46 and motor chamber 14 whilst the top of the cylinder is opened to exhaust via chamber 18, radial passages 33, bore portion 29, check valve 35, radial passages 34 and chamber 19. Movement of plunger 11 into the " lower " position (Fig. 3, not shown) delivers fluid to the top of the cylinder via chamber 17, radial passages 33, bore portion 29, check valve 35, radial passages 34 and chamber 18, whilst the lower end exhausts into axial bore 43 and bore portion 31 through chamber 14 and radial passages 45, 36, respectively. The pressure on nose 53 of valve 48 tends to unseat it but it remains closed until the pressure on nose 55 of valve 49 is sufficient to overcome spring 54. When valve 49 opens it allows valve 48 also to open whereby fluid entering bore 43 through passages 45 flows to reservoir 21 via check valve 48, valve 49, radial passage 47 and chamber 13, with by-pass valve 38 remaining closed under normal conditions. If, however, piston 22a is moved under load at too great a speed, the back pressure developed by valve 48 will cause valve 38 to open to increase the rate of flow of fluid to the top of the cylinder.

Abstract: 1,165,156. Rolling. HILLE ENG. CO. Ltd. 9 Dec., 1966 [16 Dec., 1965], No. 53434/65. Heading B3M. A reversing rolling mill includes two pairs of rolls 10, 12, 14 and 16 in tandem, which rolls are driven in opposite senses so that the pairs can be used alternately for rolling stock in opposite directions, one roll 14 of the second pair being retractable to allow rolled stock to pass freely between the second pair, when the first pair of rolls is operative. In a second pass, the roll 14 is moved downwardly to an operative position, and the stock passes to the left between the rolls 10 and 12 (the roll 12 having first been retracted to an inoperative position). The pass line 20 is slightly lower than the pass line 18. The rolls 10 and 12 are screw adjusted in a common housing 40, while the rolls 12 and 14 are movable by hydraulic rams 70 and 74 between operative and retracted positions. Shoulders 72 and 76 in the housing windows are abutted by supports 54 and 56 for the rolls 12 and 14 respectively to determine the operative positions of the rolls. Packing pieces may be inserted between the shoulders and supports, to adjust the operative positions. Similarly, packing pieces may be used for determining the position of the non-retractable rolls 10 and 16. The two pairs of rolls may be mounted in separate housings, and, if desired, a tilting table can be positioned between the rolls to guide the stock clear of the inoperative rolls when being rolled by the operative ones. The upper roll of the second pair may be non-retractable, in place of the lower roll.

Air under pressure is fed to the cylinder 65 via pressure reducing valves 74 or 75 and a solenoid valve 73. The press includes a vertical guide 84 for a loader carriage 83 supporting sets of linkages 85 attached to loader segments 86 operated by a cylinder 87 for engaging the upper bead of a tyre. A bladder locator 91 depends from the carriage and includes a part 82 urged downwardly by a spring 93 for engaging a central socket 72 of the bladder during the loading stage. On such engagement the relatively high pressure on the post 68 is changed to the lower pressure, and a vacuum prevailing in the bladder is interrupted whilst the loader is lowered to depress it. A pre-inflation pressure is then applied to the bladder followed by a relatively low hold pressure whilst the loader segments are released and the loader raised. A ring 57 has parts for the ingress and egress of curing medium to and from the bladder, the egress being assisted by a vacuum ejector. The press head 23 includes a tyre ejector 45 operated by a cylinder 42 and incorporating a toe ring 47 and bell cranks 53 pivoted to a chuck housing 46; the cranks are pivoted outwardly by downward movement of a cylinder 49 and engage under the top bead of a cured tyre. The lower end 51 of the cylinder 49 engages the central socket of the bladder. The cured tyre is raised from the lower mould section and detached from the upper mould section by the ejector and is moved laterally to beneath a stripper 96 which detaches the tyre from the ejector when the latter is raised whereby the tyre is received by a conveyer 97. The press is of the dual type comprising two sets of mould assemblies.
