Abstract: 1455317 Rolling tubes NIPPON KOKAN KK 2 May 1974 [19 June 1973] 19212/74 Heading B3M A method of rolling a tube from a hollow shell in a continuous rolling mill comprises reducing the speeds of successive stands as the trailing end of the shell passes through the mill, in order to prevent wall thickening of the final part of the tube. The shell may be rolled in eight stands while supported on a mandrel, the roll speeds initially being as shown in curve 1. If the speed of the shell corresponds to that of the rolls in stand 3, for example, the speed control starts when the trailing end of the shell has just left stand 2. At this moment the speeds of the following two stands are reduced, as seen in curve 2. Similarly, when the trailing end has passed any given stand, the speeds of the next two or three stands are reduced until the position shown in curve 5 obtains.

Title: Improvements in or relating to time switch devices for automatically making and breaking electrical circuits
IPC: G04C23/34
Filed: 1960-06-02
Abstract: 904,727. Time switches. HELIOWATT WERKE ELEKIZITATS-A.G. June 2, 1960 [June 12, 1959], No. 19593/60. Class 38 (5). In order to make circuit-closing of short duration practical in a time switch of the type in which timing is adjusted by moving sliders on a rotary timing disc, two switches 3 and 4 operated by sliders adjustable in known manner on respective 24-hour synchronously rotatable discs 1 and 2 are connected in series and the arrangement is such that during each revolution of the discs 1 and 2 the periods in which the switches are closed overlap. Thus, for example, each switch may be closed for one hour or more, but if one is set to re-open five minutes after the other has closed, the time for which the series circuit is closed is only five minutes. Preferably, the switches are double throw with the first and second contacts of one connected to the corresponding contacts of the other. Thus, the change-over of one switch closes the series circuit while change-over of the other switch opens the circuit, the switches being immediately ready for another cycle without need of restoration; this renders it sufficient to provide only one adjustable slider on each disc. A third disc 5 performs one revolution in 7 days and is employed in known manner to cancel out the action of discs 1 and 2 on particular days, for example, Sundays. The three discs 1, 2 and 5 are staggered as shown to reduce overall size.

Filed: 1931-07-10
Abstract: 381,607. Tea-rolling machines. CRAIG, W. G., Sentinel Rock Estate, Vallaramalla, Meppadi, Madras, India. July 10, 1931, No. 19935. Addition to 331,784, [Class 129, Tea &c.] [Class 129.] The indicator for tearolling machines described in the parent Specification is modified by adapting the spur wheel to move laterally so that it can rotate the indicator at different speeds. The device is driven by a shaft 1 geared to a crank of the roller table. A worm wheel 2 on the shaft 1 meshes with a gear wheel 3 and rotates a shaft 4 on which is mounted the spur wheel 5 which engages and actuates a gear wheel 6 fixed to a shaft 7 carrying the indicator arrow 8. The shaft 7 is movable laterally by a cam 9 fixed to one face of the gear wheel 6. The rotation of the shaft 7 brings the cam 9 against a lug 12 mounted on the work frame 11 and constrains the gear wheel 6 and shaft 7 to move laterally so that the gear 6 is not of engagement with the narrow edge of the spur 5<B> on the spur wheel 5, but is still in engagement with the fish-tail or broad edge of the spur 5<A>. In this position, the shaft 7 and arms 8 is rotated a distance of one tooth of the wheel 6 for each revolution of the shaft 4. When both spurs 5<A>, 5<B> engage, the arm is moved two teeth for each revolution of the shaft 4. The indicator can thus be adjusted to operate for leaf requiring differing periods of pressure.

Abstract: 643,311. Resilient drives. STONE & CO., Ltd., J., and NIXON, L. R. July 26, 1948; No. 19942. [Crass 80(ii)] In gearing for driving auxiliary equipment such as generators or compressors from the running axle of a rail or other vehicle and which is resiliently supported from the axle, an annular member or members, serving to transmit the drive from the axle to the gearing and/or to support the gearing from the axle, is centred relative to the axle by mounting screws disposed substantially radially thereof. As shown, a worm wheel 2<SP>1</SP>, Fig. 4, resiliently supported through segmental rubber pads 26 on an axle 1, is driven through interengaging dogs 30 from annular members 28 centred upon and driven from the axle 1 by pads 15<SP>1</SP>, Fig. 5, lined with friction material 16<SP>1</SP> and coupled to the members 28 through adjustable screws 22<SP>1</SP> engaging recesses in the pads. The axle 1 has a double taper, and to support the wheel 2' asymmetrically on one taper, a further annular member 32 similar to the members 28 may be provided on the opposite taper, distance pieces 33, 36 serving to locate the parts. In Fig: 6 the pads 26 are dispensed with, the members 28 being clamped directly on a flange 3' of the wheel 2<SP>1</SP> by cotter bolts 35 and supporting the wheel resiliently through rubber linings 16<SP>1</SP> of the pads 15<SP>1</SP>. In Fig. 2 (not shown) a quill drive like that described in Specification 627,653 has each flanged member 14 thereof connected to the axle 1 by eight segmental metal pads co-acting with the axle through friction linings, which may be sheet rubber bonded to the inner surfaces of the pads or rubber blocks inset therein. The pads are connected to the member 14 by lockable adjusting bolts. The coupling elements of Specification 627,653 may be replaced by rubber bushes force fitted into cylindrical cavities in the member 14 and mounted on pins connected to the other coupling member. The pads may extend axially outwards beyond the members 14, and may be engaged axially by the members to prevent rotation of the pads about the axes of their adjusting bolts. The pads may be used merely for initial centering by being mounted on a ring, which takes the place of the member 14 and can, when adjusted, be clamped to a flange on the axle by bolts passing with considerable clearance through the flange and drawing the ring and flange together into contact with interposed friction material. The quill may be held centred, while the rings are removed for maintenance purposes, by additional mounting screws which are removed before operating the gearing.

Class 135 A pressure relief valve comprises a body 10. Figs. 1, 2. with an inlet passage 13, terminating in a seat 14, with which coacts a flexible sealing diaphragm 18 secured by a ring 22 to a weight 16, and a restricted outlet 28 to atmosphere. Normal operating pressure in the inlet supports the weight and acts through a hole 24 in the diaphragm to separate the weight and the diaphragm and causes the latter to seal against the seat as in Fig. 2. If the pressure exceeds a predetermined value, the seal breaks and pressure builds up in a chamber 27 surrounding the seat, due to the restricted outlet 28, and rapidly moves the diaphragm to open the valve fully. Due to the additional area acted on by the pressure, the valve will not close until the pressure drops to a value below opening pressure. and the closure is cushioned by the fluid in space 26 between the weight and member. The diaphragm may be made of one piece of flexible material, e.g. fabric-reinforced, synthetic rubber. The space above the diaphragm is vented to atmosphere.
