Title: Improvements in or relating to coke oven batteries
Inventor: TAYLOR ALAN
IPC: C10B5/04
Filed: 1949-04-22
Abstract: 666,279. Coke ovens. WOODALL-DUCKHAM VERTICAL RETORT & OVEN CONSTRUCTION CO. (1920), Ltd. April 20, 1950 [April 22, 1949], No. 10699/49. Class 51 (ii). In a coke-oven battery of the cross-over regenerative type, such as is described in Specification 171,117, [Class 51 (ii)], the battery is divided by an unventilated division wall 2 into two sections 3 and 4, each containing an even number of ovens, and, in order to avoid lack of heat balance in the heating walls and associated regenerators on either side of such a wall and to economise in space, the heating flues 6a, 6b immediately adjacent the division wall 2 are connected by one or more cross-over flues 9 extending through or across the division wall. In an arrangement where each section of the battery has an odd number of ovens, Fig. 4, the cross-over flues 10 connecting the heating walls 6 serving the two ovens 5 on opposite sides of the division wall 2 are themselves inter, connected by one or more cross-over flues 13 extending through or across the division wall 2. With this arrangement, the gas and waste gases reversing valves are so arranged that when one of the heating walls next to the division wall is burning gas the other similar wall on the other side of the division wall has waste gases flowing therein. Dampers (not shown) are disposed in the cross-over flues in the division walls and the invention may also be applied to ventilated division walls. The division walls may also be used to carry charging cars when adjacent ovens are being repaired. When rebuilding or repairing existing coke ovens, one divisional wall may replace three ovens or two divisional walls may each replace two ovens preserving the cross-over pattern.

Abstract: 543,962. Shuttle-changing mechanism for looms. SOC. ANON. A. SAURER. Aug. 22, 1941, No. 10749. Convention date, Feb. 24, 1940. [Class 142 (iii)] On the engagement of a feeler 61 with the empty shuttle, a full shuttle 24 is drawn from a magazine 22 located above the shuttle box 4 by the box itself in the movement of the slay 1 and the empty shuttle falls from the shuttle box. The box 4 has two compartments 18, 19, and is movable vertically so that during transfer of a shuttle, the upper compartment 18 is brought into engagement with the lowest full shuttle in the magazine and the lower compartment is brought into line with the usual stationary shuttle box at the opposite side of the slay so that the empty shuttle can be picked into it. In operation, a metal sleeve 62 upon the empty shuttle 21 engages feelers 61 so that a magnet 59 is energised and a lever 54 is moved out of the path of a second lever 50. The lever 50 is mounted upon a cam disc 45 loosely mounted upon a shaft 46 and has a projection 57 arranged so that when the lever 50 is released by the lever 54, the projection, engages in a notch 48 in a collar 47 fixed to the shaft and the cam disc 45 is driven. Rotation of the disc causes, through levers 41, 39 vertical movement of the shuttle box 4. Braking means 11, 12 mounted upon holders 9, 10 pivoted upon a stud 8 within the box 4 are provided for engaging the full shuttle and the empty shuttle, and are moved into and out of holding position by slots 15, 16 in plates secured to the slay and magazine. A member 13 on the brake holder 9 also serves to cause a lever 27, lined with brake material, to hold the second lowest full shuttle 24 more firmly when the box 4 is in its highest position and transfer of the bottom shuttle from the magazine is occurring. The empty shuttle falls down a shute 69 when the box 4 is lowered and the braking means 12 is moved from engagement with it during this movement of the box.

The operating mechanism of a circuit breaker comprises two links 8, 12 pivoted together at 11, their other ends respectively carrying a pin 6 sliding in a slide 1, which is itself pivotally mounted, and pivoting about a fixed pivot 13 and an operating member 19 one end of which carries a pin 9 sliding in a fixed slide 10 and coupled to pin 6 by a link 7, the slide 10 having a right-angle portion 10a. The pivot 11 is coupled through a link 16 to a bridging contact 17 and is biased to the contacts open position by a torsion spring 14. To close the contacts member 19 is moved downwards by a pushbutton assembly 30, Fig. 5, to bring pin 9 to portion 10a of the slide, a leaf spring 22 driving it into the portion. During this operation, pin 6 moves down slide 1, which is held stationary by a latch 4, to bring links 8, 12, 16 to contacts closed position. Upon excess current flowing either in the circuit of contacts 17, 18 or, alternatively, in a separate circuit, a bi-metal 47 mounted upon an ambient temperature compensating bi-metal 49 moves a tripping member 36 to release the latch 4, thus allowing slide 1 to move clockwise and link 16 upwards to open the contacts, in its extreme position pin 6 strikes member 19 thus dislodging pin 9 from slide portion 10a and member 19 is moved upwards under a spring 41 drawing all the links back to the positions of Fig. 1. The parts of the circuit breaker are assembled between a number of moulded insulating casing parts 25, 26, 27, 28 clamped together by bolts. The tripping member 36 may be manually actuated by a second push-button 31.
