Patent GB-623147-A (GB)
Title: Recovery of precious metal values by cyanidation
IPC: C22B11/08
Filed: 1947-04-21
Abstract: A process for recovering precious metals such as gold from ores, for example slimy ores, comprises subjecting the ore to cyanidation, precipitating precious metals by means of activated carbon containing sufficient magnetic material to render the carbon particles magnetic, separating the magnetic precious metal-bearing carbon magnetically and recovering the precious metal values therefrom.  When the original ore is associated with magnetic gangue the ore is subjected first to a magnetic separation, the tailings from this operation being treated in accordance with the invention.  Magnetic activated carbon may be prepared by treating activated carbon with finely divided magnetite and an alkali metal silicate adhesive, drying and reactivating.

Title: Heterocyclic derivatives of guanidine
IPC: C07C279/18
Filed: 1977-03-15
Abstract: Heterocyclic guanidine derivatives of the formula I <IMAGE> in which the symbols are defined in Claim 1, and their pharmaceutically acceptable acid addition salts, are obtained by reacting a corresponding compound, possessing an alkylthio radical instead of the group -NR4R5, with an amine HNR4R5 in a lower aliphatic alcohol at reflux temperature and converting the resulting salt of the compound of the formula I into the free base and, where appropriate, preparing pharmaceutically acceptable acid addition salts from compounds obtained. The quaternary products can also be prepared. The compounds of the formula I, their salts and the quaternisation products, inhibit, for example, gastric juice secretion and lower blood sugar level. They can be used as medicaments.

Abstract: 961,450. Roller conveyers. FOUNDRY MANAGEMENT & DESIGN CO. Ltd. March 22, 1963 [March 23, 1962], No. 11166/62. Heading B8A. In filling foundry core boxes with sand, a roller conveyer enables the boxes to be moved to a filling position and the conveyer is lowered to permit the filled box to rest on a vibrating table. Vibration is then stopped, the conveyer is raised and the filled box removed. As shown, the conveyer comprises a top frame 1 including tie plates 1C which are welded to side members 1A and which support a plate 2 for mounting an out-of-balance motor (not shown) whereby the frame is vibrated. Each roller 7A is supported on a pair of brackets 6B mounted on longitudinal covers 4 which enclose inflatable cushions 5. To prevent transmission of vibrations from the top frame to a base frame 3, the top frame is supported on a plurality of bush assemblies 8. When the cushions 5 are inflated, Fig. 2, the peripheries of the rollers are raised slightly above the top of the frame for engagement with a box. In a modification, Figs. 4, 5, a base frame 9 supports a top frame 10C on resilient buffers 10B and, by means of arms 9E pivoted on brackets 9D, also supports rollers 9F. The lower ends of the arms 9E are pivotally connected to longitudinal members 9G of a frame 9H which is reciprocated in a horizontal plane by an hydraulic cylinder 10 having a ram 10A. On retracting the ram the rollers are caused to lie below the plane of the top frame 10C. As before, the top frame is vibrated by a motor (not shown). A pair of rollers 11 at each end of the base frame 9 assists the movement of boxes on to and away from the top frame by means of conveyers (not shown).

Each pump 6 may be driven from the axle of the carrying vehicle. The pump 10 may be engine driven. The tanks 6 may each contain a different weedkiller and each pump 5 may draw from any or all of the tanks 6. When a slurry of weedkiller is to be sprayed water or liquid, depending on whether the slurry is to contain one or a mixture of weedkillers, may be drawn from tanks (not shown) by the pump 7 into a mixing tank 8, where powdered weedkiller can be added as required, and the resultant slurry fed to the tanks 6. The tanks 6 and mixing tank 8 may be mechanically agitated. By regulation of pump 10 the proportion of water to weedkiller in the solution fed to the outlets can be varied. The pump 10 may have a pressure relief valve 11 to maintain constant water pressure by releasing excess water displaced by the weedkiller as the amount of weedkiller fed by pumps 5 is increased when the train speed increases. The water fed by pump 10 is mixed with weedkiller in the mixing vessel 3, Fig. 1, detailed in Fig. 3 (not shown).

April 16, 1931, No. 11246. [Classes 142 (i) and 142 (iii).] In a device for stopping a loom for weaving jute fabrics &c. when the weft is depleted to a predetermined degree, a feeler member 1 pivoted at 6 to a hollow member 7 secured by a screw 7<1> in the tail end of the shuttle is pressed by a spring 16 and adjustable spring 16<1> into contact with the yarn on the coreless cop 5. Normally, this moves the member 1 to a position wherein its toe 15 is clear of a notch 14 in a spring-controlled plunger 9 having a crosshead 10 movable in a cavity 10<1> in the member 7 and engaging, at the beat-up, with a bent rod 19 adjustably carried by a lever 20 engaging the loom stopping and starting lever 22. The plunger being free to reciprocate, the lever 20 is unaffected, but when the yarn is depleted, the toe 15 engages the notch 14 and blocks the plunger 9 which thereupon, at the beat up operates the rod 19 and rocks the lever 20 thus stopping the loom. In a modification described, the feeler device is attached to the usual hinged cover of the shuttle. The feeler device may operate an electric stop motion.

Abstract: 660,931. Wrapping - machines. ROSE BROS. (GAINSBOROUGH), Ltd. April 13, 1950 [April 29, 1949], No. 11382/49. Class 94(i) In a machine for forming block-ended packages, of the type described in Specification 252,216, wherein transfer members operate on wrapping material extending from the rear end face of a partiallywrapped article to form side tucks, the folding of the portion of the first-folded end flap adjacent one of the side tucks is delayed to allow that tuck to spring out to its unfolded position so that, upon folding over of the end flaps, a side flap is left projecting from the end face. As shown, the partially wrapped articles 11 are transferred from a conveyer 14 into the base of a magazine 19 by tucking members 20 and 21 which simultaneously tuck in the rearwardly-extending portions 32 of the wrapper leaving upper and lower end flaps 33, the member 21 being constituted by a rod of a diameter considerably less than the depth of the article so that the wrapper is not creased at the side where the side flap is to be formed. During the withdrawal of the members 20, 21 the lower end flap is folded upwardly by camoperated blades 34, 36, the blade 34 operating while the side tuck formed by the member 20 is still held by the tip of that member, but the operation of the blade 36 being delayed so that the rod 21 completes its withdrawal and the inwardly tucked material springs outwardly before the folding of the end flap is completed. The article is then elevated into the magazine by a cam-operated support 22 to cause the upper end flap to be folded downwardly, thus forming a triangular side flap 37, see Fig. 7 (not shown), which is folded through 180 degrees against the side face of the article by inclined portions 42 and 43 of a folding member 39.

Abstract: 138,785. Maaskamp, J. J. May 7,1919. Boat raising and lowering gear; davits; chocks. -Relates to gear in which the davits are luffed by sliding bars operated by the winch for the boat-supporting cable and consists in providing the davits with a clamp which grips the gunwale of the boat when on the chocks under the influence of the tension in the cable. The davits are pivoted in the plane of the boarding and are additionally supported in the outboard position by pivoted bars. The boat 1, Fig. 1, rests on cleats 2 between davits 3 which are pivoted at 4 and slotted at 7 so that the part 6 may slide in the slot and support the davit in the outboard position. Driven by the winch gear is a pinion 23 which gears with a rack 24 on a slide-rod 25, the latter when moved outward pushes the davit past its dead centre, the boat being lifted off its chocks. At the same time, the winch pays out the cable until the davit is full out, and finally the boat is lowered. The top of each davit carries a journal 9, Fig. 3, from which depend two lugs 10 carrying a pulley 11, and on which also is a cramp or brake 12 in proximity to or contact with the gunwale 13. The cable attached to a ring 14 on the boat passes over the pulley 11, thence over guide-pulleys 16, 17 to the winch or winches. When the boat is on the chocks, the tension on the cable pulls the cramp 12 into contact with the gunwale 13 and holds the boat firmly. The boarding is recessed to take the davit when slung inboard.
