Abstract: 1,004,308. Wells, &c. CONTINENTAL OIL CO. Nov. 8, 1963 [Dec. 7, 1962], No. 44238/63. Heading El F. A fluid for fracturing wells comprises a carrier liquid and a bactericide comprising 100-100,000 p.p.m. by weight of carrier liquid. The carrier liquid is water or other low-cost liquid stable at well pressure. The bactericide is effective against Desulfavibrio bacteria and may comprise quaternary ammonium compounds, amine silico-fluorides, mercuric compounds, amines and amine salts, halogenated aryl compounds, and antibiotics. The bactericides protect the well metal from corrosion, the quaternary ammonium compounds and the amines also acting as foamers. A water soluble quaternary ammonium compound when used between 200-3,000 p.p.m. lowers the surface tension of the water. The fluid may contain 0À1 to 25 % by weight of a fluid loss agent such as siliceous or vegetable material, or substances which form gels. Particulate fluid loss agents have sizes ranging from À01 to 50 microns so that partially soluble bactericide particles may also act as agents. Fracturing fluids contain a propping agent the weight ratio of agent to liquid lying between 1:100 and 5:1. The propping agent which may be of aluminium, ceramic, porous concrete, or diatomaceous earth may be filled or coated with the bactericide. Prior to fracturing a well was treated with 20 % hydrochloric acid followed by water containing gelling and fluid loss agents. The fracturing fluid as injected at 1,100 p.s.i. and comprised local water, a propping agent (sand), a gelling agent (partially hydrolized starch), a fluid loss agent (silica flour) and a bactericide (a mixture of alkyl substituted benzl trimethyl ammonium chlorides).

Abstract: 1,176,037. Rolling. USINOR. 29 Sept., 1967 [30 Sept., 1966], No. 44438/67. Heading B3M. [Also in Division B8] Bars fed in a direction F from a rolling mill (not shown) are conveyed across a cooling bed to a roller conveyer 8 which enables the heads of the bars to be aligned. A driven roller 10 comprises two steel members 10a, 10b separated by a brass disc grooved at 12. One of the members 10a or 10b houses an electromagnet which may be de-energized by actuation of a plate 23. A bar received in the groove 12 completes the field between the members 10a, 10b. Additional support for the bar is provided by idler wheels 18 and by guides (21), Figs. 3, 4 (not shown). Bars 7a, 7b, 7m, having their heads non-aligned are conveyed transversely of their length by mobile racks 2 of the cooling bed which also includes fixed members 1. When a bar reaches the conveyer 8, it is moved longitudinally until drive to the roller 10 and current to the electromagnet are disconnected by engagement of the head of the bar with the plate 23. The bar is then deposited on a plate 3 where, with other bars, a group is formed and is fed on to driven rollers 6 which discharge in direction G towarsd shears. By operation of the plate 23 the heads of all bars are substantially aligned.

Filed: 1971-09-23
Abstract: 1343345 Valves SLOAN VALVE CO 23 Sept 1971 [23 Sept 1970] 44491/71 Heading F2V A water flushing assembly, comprises a manually-operated push-button actuator 13, a flush valve 7 and a valve actuating unit 14, the actuator, the valve and the unit being interconnected by two flexible conduits 15, 16 so allowing the actuator 13 to be remotely disposed relative to the remainder of the assembly. Conduit 15 communicates with the supply line 9 to the flush valve 7. When the push-button 12 is depressed and hence the ball valve 35 of the actuator 13 is unseated, conduit 15 feeds the second conduit 16 in consequence of which a piston 75 of unit 14 is displaced towards the right, as seen in Fig. 3. Such displacement causes, by way of a piston stem 77 and a valve stem 90, tilting of the flush valve member 84 and hence opening of the flush valve 7. On subsequent release of the push-button 12, the assembly returns to the state shown. Should the push-button 12 not be released, the flush valve member 84 is still allowed to return to its seated state by virtue of the fact that the valve stem 90 is of telescopic nature and so can rest on the piston stem 77 when valve member 84 is seated. Piston 75 is formed with a bleed 81 by way of which the actuating fluid can discharge from behind the piston to the flush valve outlet 10, such discharge taking place through a passage 80 inclined toward the outlet 10.
