Title: Gage control method including consideration of plate width effect on roll opening
IPC: B21B37/60
Filed: 1970-04-01
Abstract: 1,263,227. Rolling. GENERAL ELECTRIC CO. 1 April, 1970 [28 April, 1969], No. 15367/70. Heading B3M. A method of controlling the gauge in a plate rolling mill comprises establishing a base figure for the roll opening at the mill centre line in accordance with the desired edge gauge of a plate and the predicted stretch of the mill at the plate edges at the expected force levels, establishing an offset in accordance with the unloaded configuration of the rolls and the width of the plate to be rolled, the offset being substantially equal to the total space existing between adjacent roll surfaces in an unloaded condition at a location corresponding to the edge of the plate to be rolled, combining the base figure and offset to establish the proper centre line roll opening, positioning the rolls according to the proper centre line opening, and passing the plate between the positioned rolls. The offset Gw is calculated from the equation C(W/R)<SP>2</SP> where C is the effective crown on the rolls, W is the width of plate being rolled and R is the length of the mill rolls. An approximate offset can be calculated from the equation KC[(W - M )/(R - M)] where K is a constant determined by the unstressed configurations of the faces of the rolls, M is the minimum plate width to be rolled at the mill stand and C, W and R are as defined above.

Title: Improvements in apparatus for the delivery of tickets or other vouchers connected together in the form of strips
IPC: G07B5/02
Filed: 1934-05-23
Abstract: 443,544. Ticket - issuing machines. LANDIS & GYR AKT.-GES., 1, Hofstrasse, Zug, Switzerland. May 23, 1934, No. 15421. Application for addition to 403,835. Void [Abridged as open to inspection under Sect. 91 of the Acts, Nov. 27, 1934]. [Class 106 (iii)] The apparatus described in Specification 403,835 is modified so as to prevent rebounding of the voucher drum when it is stopped by the first abutment formed by one of the levers. The strip feeding drum 22 is in this case locked and unlocked by the lever 13, the end of which carries a roller 65 adapted to press on the cam tracks 69 on a feed and detent wheel 66 rigid with the feeding drum 22 and finally to engage slots 67 in the wheel. When the operating sector 7 is moved from the rest position shown in chain dotted lines through an angle which depends upon the number of tickets to be issued, the shaft 6 and lever 12 are turned through the same angle, whereby the knife 33 is withdrawn, the pawl 56 is moved clear of the stop 57 so that it may click over the ratchet wheel 16, and the lever 13 is rotated in the same direction but with a varying velocity ratio. The roller 65 thus unlocks the feeding drum. The lever 13 is operated from the lever 12 by mechanism consisting of a toothed segment 59 meshing with a segment 58 on the end of the lever 12, a pin on the segment 59 engaging a slot in the lever 13. A circular segment 62 movable with the segment 59 engages a corresponding segment 64 on the end of the lever 13 so as to lock the lever when a pin on segment 64 leaves its slot. During the return movement of the operating sector 7 with its shaft 6 and lever 12, the pawl 56 rotates the ratchet wheel 16 and, through gearing rotates the feeding drum 22 and detent wheel 66, thereby feeding out all but the last stamp. The pawl 55 is then disengaged by the stop 57, but the drum 22 is still fed forward by the roller 65 on the end of lever 13 engaging one of the cam surfaces 69 until it enters a slot 67 and locks the drum. The knife 33 is then operated by the end of the lever 12.

Abstract: 1,039,608. Moulding tyres. E.I. DU PONT DE NEMOURS & CO. April 23, 1963 [May 11, 1962], No. 15901/63. Heading B5A. Tyres are produced by bonding a first member comprising a tread element 10 stitched to a cincture belt 9, or the like, to a carcass member, comprising sidewalls 3, 4 and a layer containing reinforcing panels 2, in a vulcanizing press. The carcass member is placed over the expansible diaphragm 14 of a vulcanizing press and the first member held firmly, without buckling, around it, by several arcuate tread mould pieces 15. Hot fluid at 4-50 lb. per sq. inch is then introduced into the diaphragm to expand the carcass into contact with the first member, whilst the side mould wall members 12, 13 are partially closed to ensure alignment of the carcass member with the first member. The mould is then completely closed (see Fig. 3, not shown) whilst the pressure of the fluid is increased, to counteract the inward movement of mould parts 15, and the tread portion is moulded with no substantial change in radius of the first member, thus effectively eliminating any residual stresses or buckling in the crown of the tyre. When the mould is fully closed both the temperature and the pressure of the fluid within diaphragm 14 is raised and the tyre cured. The tyre may be removed when partially cured, reinflated, and the cure completed outside the mould.
