Abstract: 708,191. Actuation of switches. REYROLLE & Co., Ltd., A. April 23, 1952 [April 23, 1951], No. 9390/51. Class 38(5) A spring-closed circuit-breaker has a movable contact A pivoted at A<SP>1</SP> and connected to an arm D<SP>1</SP> of a bell-crank D, the main closing spring E being connected to the arm D<SP>2</SP> thereof, a further arm D<SP>3</SP> having an auxiliary spring F connected thereto. In the open position shown, the spring F opposes the spring E but as the bell-crank D is moved counter-clockwise by the spring E, the spring F moves across a dead-centre position in line with the arm D<SP>3</SP> and then acts in.the opposite sense to assist the spring E. The arrangement is preferably such that the energy of spring F is the same in the open position as it is in the position at which the contacts just begin to engage, Fig. 3 (not shown), so that the contact speed is determined by the spring E which may be adjustable. Each spring may be replaced by a battery of springs. In a modification (not shown) the arm D' carries a roller acting on a cam surface carried by the contact arm so as to modify the characteristics of the combined springs.

Filed: 1975-03-06
Abstract: 1500791 Continuous casting FIVES-CAIL BABCOCK 6 March 1975 [8 March 1974] 9414/75 Heading B3F A structure for supporting and cooling a continuously cast strand comprises one or more panels and each panel comprises parallel bars 12, Fig. 5, 30, Fig. 11, or 46, Fig. 16, which are transverse to the direction of strand movement with elongate spray distributers 16 or 40 between and parallel to the bars, each bar supporting the strand 32 or 50 by a portion (the upstanding web in Fig. 5, or one of several transverse ribs 38, Fig. 11, spaced along a corresponding upstanding web 36 which does not extend as far as the ribs 38 towards the strand 32, or a transverse rib 48, Fig. 16) which portion has a support surface to contact the strand, the width of the surface being small in relation to the distance between adjacent portions, and also has parallel lateral surfaces larger than the support surface. There may be stress-relieving grooves (26) in the support surfaces. Edge faces of cast slab may be similarly supported, the panels being applied by jacks or springs.  Each bar, Fig. 16, may have two, angled, longitudinal main portions 46 between which vapour from coolant from the distributers 40 may discharge. The ribs 48 join and brace the lengths 46 and provide the faces for contacting the strand 50. The bars may be formed in separate longitudinal halves, each half-bar having one main length 46 and half-ribs 48, Fig. 18 (not shown). As shown in Figs. 5 and 11, however, the bars 12 and 30 are of general T form in section and the distributers 16 and 40 seat in flanges formed by the cross bar of the T. Vanes 22 for flanking the jets and creating discharge passages for vapour are integral with or fixed to the bars or fitted to the distributers. Notches 18 in the flanges provide vapour outlets. The distributers are fed with water and possibly air. Small tubes (24) Fig. 7 (not shown) may provide jets of air for driving excess water off from the area near the face contacting the cast strand. The tubes may be connected to air chambers extending the length of an atomizing distributer. The bars may be releasably secured, e.g. bolted, on frames or end girders (10) to form the panels which may be associated with guide rollers, plates or grids. Alternatively, a unit may be formed by assembling a number of bars side-by-side by tierods (54, Figs. 19, 20, not shown) extending through oversize holes in their ends to allow for adjustment. Such a panel has eyes (58) at each end whereby the unit may be pivoted on a support, a roller assembly frame or mould base. The frame or side members (10) may be shaped to accommodate a curved strand and/or the bar positions adjusted by wedges (20). For the same reason, the strand-contacting faces may be convex, e.g. part-cylindrical as indicated in Fig. 16. The bars need not be perpendicular to the direction of strand movement, but can be relatively skew or of chevron form, Fig. 10 (not shown).

Filed: 1947-04-14
Abstract: 632,859. Controlling change-speed gear. HAMILL, W. W. April 14, 1947, No. 9833. [Class 80 (ii) In an engine control means for a reversing gear in which an operator-controlled member regulates the speed of the engine and operates a fluid pressure servo-motor for engaging the drive, the control of the servo-motor is effected through a geneva gear mechanism. A cam 17, rotated manually through a spindle 18, effects control of the engine speed through a spring-loaded follower lever 19 which acts through a telescopic link 30 on the engine throttle, ignition or fuel pump, the cam being notched at mid-position 26, 27 to co-operate with a spring detent 25 to give a positive neutral position at the lowest engine speed. Rigid with the cam 17 is the wheel 31 and pin 23 of a geneva mechanism 21 which rotates a spindle 11 having a pinion portion 11 (Fig. 1) meshing with a rack 10 in the outer wall of an axially slidable cylinder 2 carried in a stationary cylinder 1. Axial movement of the cylinder 2 caused by substantially half-travel of the cam 17 and geneva mechanism opens inlet and exhaust ports 8, or 9 and 8a or 9a respectively to allow pressure fluid in the passage 6 to move a piston 3 axially to change gear from forward to reverse or vice versa through the rod 29 coupled to the gear lever 35, the exhaust fluid, which may be engine oil being returned to the system through the passage 7. Thus rotation of the spindle 18 slows the engine, changes gear and increases engine speed for each direction of rotation. To relieve the gear shift mechanism of thrust loading the rod 29 is connected to the gear lever 35 through a pin 34 in a kidney-shaped slot 32, the pin riding up the centre slope 37 during change and falling, under the weight of the mechanism, on the other side of the slope when movement ceases, thus reversing the motion of the lever 35 slightly. Other forms of this mechanism are shown in which the central projection of the slot is adjustable.
