Title: Improvements in the art of shaping metal sheets
IPC: B21D5/14
Filed: 1929-06-07
Abstract: 333,675. Carns, E. B. June 7, 1929. Aircraft; boats. - In curving metal sheets in the longitudinal and transverse directions, for use in aircraft and boat construction, &c. the sheet is pulled through a die or rolls for imparting the transverse curvature, the rolls &c. being at the same time moved in a direction obtuse to the direction of pull so as to pull against the sheet and thus effect the longitudinal curvature. A rigid and stiff sheet with inherent tension is thus obtained with the arcs of the longitudinal and transverse curves intersecting at all points. The rolls 10, 11, the pass of which is adjustable by screws 15 through springs 16, are mounted in housings 12, which are pivoted at 19 to the base 18. To the housings are pivoted on the shaft 28 a track member 23, which rests on a roller bearing 25 so as to allow it to rock. The sheet, which may have flanged longitudinal edges, after passing through the rolls is clamped to a wheeled carriage 26, which has links 42 engaging a pair of chains 30 so that it may be traversed on the track. The chains are driven by spur gear 33-36 from a hand-driven shaft. The rolls may be idle or may be rotated in either direction at a greater or less speed than 'that of the carriage by a chain 38 through a clutch 41. The roll 11 may be given a greater speed than that imparted by the shaft 28 by using a ratchet clutch and driving the sprocket 37 on the roll shaft. During traverse of the carriage the roll housings are moved on the pivots 19 by a cam 22 which is rotated from the gear train or independently. A scale and indicator 47 show the tilt of the housings.

Abstract: 650,410. Automatic selectivity control. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. June 30, 1948, No. 17623. Convention date, Sept. 24, 1947. [Class 40 (v)] In an amplifier having the band-width varied by positive feed-back from a succeeding stage, negative feed-back is introduced for correcting the frequency response of the circuit. Two I.F. stages T1, T2 are coupled by a tuned transformer L1, C1, L2, C2, and positive reaction is supplied from the cathode of T2 through condenser Ca. To correct for the consequent distortion of the frequency characteristic, negative feed-back is supplied by tertiary winding L3. The degree of feed-back is varied by an A.G.C. voltage applied to the control grid of T2, and thus the selectivity varies inversely with signal strength.

Title: Improvements in or relating to cylinder liners
IPC: B23P11/00
Filed: 1934-06-15
Abstract: 434,298. Making engine cylinder liners. STOKES, F. W., and SHEEPBRIDGE STOKES CENTRIFUGAL CASTINGS CO., Ltd., Chesterfield, Derbyshire. June 15, 1934, No. 17799. [Classes 83 (ii), 83 (iii), and 83 (iv)] In a method of lining the cylinders of internalcombustion or steam engines, pumps, air compressers, &c. with liners which are a force fit within the cylinders, the liners are prefinished in a jig which imposes upon them compressive stresses similar to those produced by the cylinder whereby the liners, after insertion in the cylinders, will be finished accurately to size. In order to produce the required stresses, the wall thickness of the jig may approximate to that of the cylinders. A cast liner is rough turned and bored, then finish turned, pressed into the jig and finish bored, pressed out of the jig and finally pressed into the cylinder. In order to compensate for permanent compression produced in the liners by insertion in the jig, the jig and liners may be made oversize, but with the same force fit allowance between them, in order to pre-stress the liners before finishing. The pre-stressed liners are then turned to size on the outside, pressed into the jig for interior finishing and finally removed and pressed into the cylinders. The liners may be retained within the cylinders solely by the force fit or may be provided with retaining flanges or a stepped exterior to assist the force fit. The method may be used with wet or dry liners, or with liners which are heat treated or surface hardened, in which case the pre-finishing operation in the jig is performed at a suitable stage of the heat treatment.

Title: Cyclic desorption refrigerator
IPC: F25B17/08
Filed: 1968-04-16
Abstract: 1,215,731. Refrigerating; thermal valves., RESEARCH CORP. 16 April, 1968 [29 May, 1967], No. 17807/68. Headings F4H and F4U. A load is cooled by negative heat of desorption of a gas from an adsorbent. As illustrated, a cold gas refrigerator 10 cools a thermally conducting block 13 which is connected by thermal conductors 15 and 17 and a thermal valve 16 to a chamber 18 containing a helium adsorbent 19 which may be activated charcoal, silica gel or a zeolite. The adsorption chamber 18 is connected by thermal conductors 28 and 30 and a thermal valve 29 to a thermally conducting block 31 on which is mounted a load 32 to be cooled. A gas duct 20, 21, 22, having a part 14 in heat exchange relationship with the block 13, is connected to valves 25 and 26 for the supply of helium 20 and its withdrawal from, the adsorption chamber 18. The thermal valve may be of the type operated by the supply of gas to, and its evacuation from, a space between two thermally conducting plates, Fig. 2 (not shown), or may be of the type operating by a magnetoresistive effect, Fig 3 (not shown). The system operates as follows. Helium is admitted to the chamber 18 until the required amount has been adsorbed. During this step, the valve 16 is open and the valve 29 is closed so that heat of adsorption is taken up by the block 13. The valve 16 is then closed, and helium is withdrawn from the chamber 18 which is therefore cooled by the negative heat of desorption. When the chamber 18 has reached the required temperature of the load, the valve 29 is opened and helium withdrawal is continued until desorption is substantially completed or until a predetermined low pressure is reached in the chamber 18. At this point, the valve 29 is closed and the admission of helium to the chamber 18 is resumed. When the temperature of the chamber 18 has risen to that of the block 13, the valve 16 is opened, thereby commencing the next cycle of the system. In alternative embodiments, Figs. 4 and 5 (not shown), the conductors 15, 17, 28 and 30 are omitted, as are the thermal valves. Transfer of heat between the components of the system is accomplished by oppropriately controlling the flow of heat exchange gas in pipes which are arranged in heat exchange relationship with the components.
