Title: Method of, and apparatus for, pressing a sheet of metal to non-planar form
Inventor: MCNALLY PERCY WILLIAM
IPC: B21D22/02
Filed: 1956-02-23
Abstract: 804,575. Stamping. CARBODIES, Ltd. Jan. 29, 1957 [Feb. 23, 1956], No. 5591/56. Class 83 (4). A method of pressing sheet-metal to non- planar form, e.g. cupping, involves using a pair of press tools 10, 11 having respectively a peripheral ridge 12 and a coacting recess 14 for forming a peripheral channel in the sheet 18 to hold it in stretched condition while the coacting dies of the tools carry out the pressing operation, the outer wall 21 of the ridge coacting with a resiliently-supported, e.g. spring-loaded, annular member 19 to grip a marginal portion of the sheet prior to the pressing operation. The side walls 16 of the ridge and the side walls 17 of the recess are spaced apart by an amount less than the thickness of the sheet. The annular member 19 may be adapted to lift the pressing out of the lower tool 10 after the pressing operation. Alternatively, the member 19 is supported by a pneumatic piston and cylinder. In a modification, the annular member 19a (Fig. 3) is supported by bolts 26a attached to marquettes 31 and the tool 11a has a downwardly-depending portion 32, the lower surface 33 of which cooperates with the member 19a to grip an outer portion 35 of the sheet. Thus the sheet is gripped between three different sets of surfaces. Specification 804,574 is referred to.

Title: Improvements in and relating to stockings and a method and machine for the manufacture of stocking blanks
IPC: D04B11/28
Filed: 1945-03-13
Abstract: 616,529. Knitting. DOWLAIS HOSIERY MILLS, Ltd., HOOPER, H. and EDWARDS, A. G. March 13,1945, No 6215. [Class 74(ii)] In the manufacture of a blank for a round heel stocking on a straight - bar machine, a number of carriers are provided for the instep and at least one carrier is provided for each heel part so that the heel parts and instep are knitted of separate weft yarns with an overlap as in split work, and spaced courses are knitted in the heel parts which are omitted from the instep part. The instep carriers are operated one at a time in the same direction as the heel carriers. As described there are two instep carriers 7, 8, which initially are positioned one at each margin b, b<1>, of the instep, and a carrier 5, 6, for each heel part H, H<1>, of which carrier 5 is initially positioned at the selvedge of the heel part H and the other at the margin b<1> of the opposite part H<1>. Upon operation of the carriers, the heel carriers 5, 6 move to feed their needles and one instep carrier 7 moves across to feed the instep needles. On reversing this motion the heel carriers return to their original position but the second instep carrier 8 now feeds the instep needles, the first 7 being retained out of operation in the second carrier's initial position. On the third draw the instep carriers 7, 8 remain out of operation allowing an additional heel course to be knitted in excess of the instep courses. This operation is repeated at every third draw of the carriers so that for every three heel courses knitted two corresponding courses are knitted in the instep. The heel carriers, in addition, feed yarn to at least one needle of the instep at each margin b, b<1>, so that an overlap, as in split work occurs. To prevent the instep needles 14 from pressing off during the course when the instep cariers are inoperative, instruments 11 are fitted between the knocking-over bits 12 and the knocking- over bar 10 is given an additional forward motion so that the instruments bend the needles 14 and prevent them from engaging the pressing edge 15. Alternatively a ledge on the knocking-over bar, a divided presser, or a divided needle bar may be employed for this purpose.

Abstract: 525,669. Centrifugal separators. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 25, 1939, No. 6278. Convention date, Feb. 25, 1938. [Class 23] [Also in Group XXVI] Liquid particles are separated from a stream of gas or vapour, as for instance a stream passing from the high pressure turbine 10 to the low pressure turbine 14. by means of a deflecting wall 24 the rim of which penetrates a channel 27 arranged in the connecting conduit 16 between the two machines. The wall 24 is substantially conical and its surface is formed by the revolution of a curved line about an axis. An edge 29 of the channel 27 is secured to the rear surface of the wall, and the parts are supported by brackets 31. Liquid particles in the gas stream impinge on the wall 24 and pass to the channel 27 from which they fall through the conduit 30 to the vessel 21. This vessel has a discharge pipe 22 controlled by a valve 23 which may be operated manually, or automatically, by a float. In a modification a number of deflecting walls 24 may be employed and may be arranged in series or in parallel. Specification 488,055, [Group XXVI], is referred to.

Title: A new or improved fluid drive
IPC: F16D35/00
Filed: 1957-02-26
Abstract: 806,044. Hydraulic couplings. YULE, I. M. Feb. 26, 1957, No. 6367/57. Class 69 (2). An hydraulic coupling comprises a toothed disc 54 driven by an input shaft 17 and a rotor 56 driving an output shaft and having radial slots housing vanes 58. Each vane is relieved slightly to allow passage of oil to its outer end. Rotation of disc 54 causes circulation of oil and the increased pressure at the outer end of each vane moves them inwards, the oil then impinging on the faces of the vanes to drive the rotor. As the speed of the rotor increases, the vanes are moved outwardly by centrifugal force until finally they are completely housed within their slots and the rotor is driven solely by the viscous drag on the inner surface. There is thus obtained a flexible drive with a relatively high initial torque. The rotor 56 drives the output shaft through epicyclic reduction gearing. Specification 806,043, [Group XXIII], is referred to.

Title: Improvements in or relating to coking retort oven batteries with regenerators
IPC: C10B5/10
Filed: 1923-03-06
Abstract: 209,380. Becker, J. Jan. 2, 1923, [Convention date]. Coke ovens. - Relates to regenerative coke ovens of the kind described in Specification 171,117, in which the heating- flues 17 on opposite sides of alternate ovens are connected by cross-over flues 26, and consists mainly in applying these flue arrangements to a battery having longitudinal regenerator tunnels. As shown in connection with an oven having provision for heating either by a rich or a lean gas the heating- flues in each wall are arranged in two half-wall groups, M, N having independent connections to their corresponding subjacent regenerators so that the firing of the ram side of the bench can be controlled independently of that of the. coke side. Each of the four regenerator tunnels is divided by transverse partitions 22 into compartments 18 each corresponding with a pair of similarly-functioning heating-walls, each of the outer compartments A of a transverse row being connected with its associated heating-flues through a half-sole flue 62 and ports 63, and each of the inner compartments through a pair of flues 72 and ports 73. In operating with lean gas, air and gas are heated respectively in the outer and inner compartments A, P of alternate transverse rows. and the waste gases are exhausted through all the compartments of the intermediate rows. When using rich gas, the. air is heated either in all the. compartments of alternate transverse rows, or in the outer compartments only, the inner ones then being used for the supply of diluent gas. Alternate ovens of the battery are heated on both sides by flame heat or waste gases according to the phase of operation, while the remainder are heated in both phases by flame on one, side and waste gases on the other. In a modification, the regenerator connections are so made that the two outer tunnels and the two inner ones function similarly, i.e. all the outer compartments of the transverse rows are on air or gas at the same time, while the waste gases are exhausted through all the inner compartments, and vice versa. This regenerator arrangement is also used in ovens fired bv rich gas only, each regenerator compartment being then connected with one heating-wall.
