Abstract: 628,772. Ammunition hoists. VICKERS-ARMSTRONGS, Ltd., and BRERETON, C. F. Oct. 1, 1947, No. 26520. [Class 92 (i)] [Also in Group XXX] A load-conveying hoist comprises a guide connected between a lower loading point and an elevated unloading structure such as a gun platform, the structure being displaceable to vary the distance between the two points, and the guide being free to change its effective length automatically according to the change in distance between the two points. Furthermore the invention provides means to feed loads in succession along the guide and automatic means to adjust the effective range or length of operation of the feeding means according to the changes in effective length of the guide. The guide comprises telescopic parts la, 1b, connected between a gun turret 4 and a deck plate 7. The guide carries pivoted pawls 10 and pawls 11 operated by rams 15, 16. The pawls 11 move in slots in the guide and are carried by a vertical rod 12 connected by a cross-piece 13 to the rod 14 of the ram 15. The second ram 16 parallel to the first has a rod passing through a cross-piece 18 connected to the upper end of the ram 15 and having a cross-head 19 carrying the uppermost pawl and also a lug 20 attached to a shaft 21 guided through a lug 22 at the upper end of the ram 16 and in driving engagement with a crank 23 and operating a cut-off valve 24 of the shuttle type. The valve has relative motion to its rod 24<SP>1</SP> between stops 24a, 24b, for giving a quick reverse motion to the rams. Opposite ends of the valve are connected by leads 25, 26, to the rams. The valve moves between seatings 28, 29, the seatings 29 having a bleed opening 29<SP>1</SP> to control the speed. The upper section 1a of the guide has an abutment 31 which is struck by a lever 32 on the cross-head 19, the lever being linked to a crank on the shaft 21, whereby a partial rotation of the shaft drives the rod 24<SP>1</SP> against a spring allowing the valve to seat in the seating 29. The connection of the rams to the source of pressure is by means of a control valve 34 between valve 24 and cut-off valve 35. The fluid is admitted until the lever 32 strikes the abutment 31. On movement of the valve 34, the rams are retracted. To position with the gun breech, the guide may have an upper part 1c swivelling about an upper pivot.

Patent GB-917966-A (GB)
Title: A method of producing an iron-nickel and/or-cobalt alloy from nickel-and/or cobalt-bearing iron ores
IPC: C22B23/02
Filed: 1959-08-06
Abstract: A process for the production of enriched iron alloys from iron ores containing nickel and/or cobalt comprises first heating the ore with carbonaceous material to reduce it to a substantially solid mass containing elemental iron, which is subsequently smelted under conditions whereby the iron serves as substantially the sole reducing agent for producing the nickel and/or cobalt.  A part only of the iron content may be reduced in the first heating step.  The iron should be obtained by reducing one portion of ore at from 900 DEG  to 1100 DEG C., the mass being then mixed with a second portion before carrying out the smelting.  The first heating 2step may be carried out in a rotary kiln in which the temperature is such that the oxides of chromium, phosphorus and manganese are not reduced.  An additional portion of ore, with or without added fluxes, may be heated by placing it on the outer shell of the kiln prior to mixing the said portion with the initial mass for addition to the smelting furnace. The mass when incandescent may be covered with a layer of dried and preheated ore, with or without added fluxes, during conveyance from the kiln to the furnace.

Patent GB-269982-A (GB)
Abstract: 269,982. Theobalds, R. O. P. Jan. 28, 1926. Grates of open fireplaces, particularly for burning coke and anthracite, are formed of deep bars spaced widely apart and much narrower than the spacing; e.g. for a spacing of #" or more the bars may be #" to ¢" in width. In the grate shown in Figs. 1 and 2, the bars b are inclined and attached at their front ends to a plate a having a vertical front portion a<1>, by means of flanges c, which serve also to space the bars. Flanges d at the rear ends of the bars are received in a channelsection member e. The end flanges may be formed by twisting the ends of the bars. In a modification, the bars are inclined upwardly from the plate a, which may be inclined, as shown, or horizontal. In a further modification, the plate a is dispensed with, the bars being inclined downwardly from the rear and then extending upwardly at the front of the grate. Fig. 5 shows a construction comprising bars b extending below a raised plate a, and from side to side of the grate, by which means ashes are prevented from coming to the front of the hearth: in a modification of this form, the rear part of the fuel-supporting surface may be solid. The fireplace may be provided with a blower to facilitate lighting. Specifications 248,101, 256,839, and 268,083 are referred to.

Title: Improvements in or relating to electrostatic precipitators
IPC: B03C3/76
Filed: 1954-09-20
Abstract: 764,894. Electrostatic precipitators. HOLMES & CO., Ltd., W. C., SYKES, W., and ARMITAGE, F. Sept. 20, 1954, No. 27109/54. Class 39(1). A tripping device for the rapping mechanism of an electrostatic precipitator comprises three cooperating claw-like bell crank levers 3, pivoted at 6 and engaging with rollers 9 on pin 17 .between the limbs of a connecting rod 5 threadedly engaged with shaft 18 connected to hammers, which levers 3, after a predetermined upward movement through the links 4 and insulator 19, separate by means of a toggle action, caused by the spring connected rods 14 to which the upper ends of the levers 3 are connected, and allow the hammers to fall under their own weight against action of spring 16 to effect rapping. During the upward motion a roller 11 on the pin 6 moves in slot 2b and rollers 12 on rods 14 move in slots 2a to ultimately contact pins 17 at upper ends of the slots and effect the toggle action. The upward movement of the pin 17 connected to the hammers can be adjusted by adjusting its position in spaced bores 21 in the limbs of the rod 5. A stop pin 3c carried between the levers 3 is arranged to abut against the under side of the upper arm of the inner lever 3 to limit the opening movement of the claw members. The upward and downward movement of the mechanism is effected by upward and downward movement of the insulator 19. One pair of side pieces 2 is detachable by removal of nuts on bolts 23 and pins 7.
