Title: Underwater anchor apparatus and methods of installation
IPC: E21B17/02
Filed: 1972-01-13
Abstract: 1359961 Anchoring of marine structures BAKER OIL TOOLS Inc 13 Jan 1972 1614/72 Heading B7S [Also in Division E1] A cable 17 is anchored to a sub-aqueous formation F penetrated by a borehole 10 by releasably securing a body 13, 23 to a tubing string 11, lowering the string and body from a floating vessel (not shown) to locate the body in the borehole, lowering the cable along the string to the body, securing the cable to the body, and releasing the string from the body and withdrawing the string to the vessel. The member 13 is an anchor which also cuts a shoulder 10a into the formation and the member 23 is a torque sub which transfers torque from the string to the body by means of flats 28 engaging flats 27 in a coupling 24 at the lower end of the string. On the vessel a bit 12 is secured to the anchor 13, and the sub 23 is fixed to the anchor which is releasably fixed to the coupling 24 by dogs 31 held projected by a holding sleeve 36, the members 14, 15 of the anchor being held retracted. The apparatus is lowered on the string and the hole is drilled in the formation, drilling mud being circulated. After the hole is drilled a trip ball 84 is dropped to rest on a seat 85 of a piston structure 61, 77 which is then moved downwardly by the mud pressure. The surfaces 62 on the expander 61 move the cutter members 14 outwardly so that as the string is rotated the shoulder 10a is cut. As cutting proceeds the expander surfaces 63 engage the anchor members 15 to expand them outwardly, the expansion trailing the expansion of the cutter members. Finally the parts reach the positions shown in Fig. 7c, and the mud passes through holes 88 to the bit and annulus. The cable and coupling members 91, 92, 93, 95 are lowered through the string to latch members 93, 95 to the holding sleeve 36. A pull on the cable shifts the sleeve 36 to release the dogs 31 to free the coupling 24 from the torque sub so that the string and coupling may be stripped along the cable to the vessel. The cable connector 108 may be attached to a buoy. In a modification (Figs. 11a, 11b, not shown) a string of drill collars which extend above the formation is interposed between the anchor and the torque sub 23, the latch members for the cable latch to an external shoulder on the top of the string of collars and the holding sleeve is moved by a trip ball. In a further modification (Figs. 13, 15, not shown) the anchor is dispensed with, a string of collars extending above the surface of the formation is cemented to the formation, and a ring at the end of the cable is fixed on the string by a band latched to the top of the string.

Abstract: 778,160. Electric indicator systems. MINISTER OF SUPPLY. Jan. 15, 1953 [Jan.21,. 1952], No. 1712/52. Class 40 (1). The transmitter of a remote reading compass carried in a vehicle consists of two coils mounted perpendicular to each other with mu-metal cores, and rotated continuously in azimuth in the Earth's magnetic field. The resultant periodic fluctuation of the inductance of the coils is employed to indicate the vehicle heading with respect to magnetic north on a cathoderay tube. As shown, Fig. 2, the coils C1 C2 are mounted on the plate 1 which is rotated continuously by the motor M. The oscillators O1, 02 transmit two different frequencies, frequency modulated, one by a function sin # and the other by a function cos #, where # is the angle of one coil with respect to magnetic north. At the receiver, two unidirectional voltages are developed which correspond respectively to sin # and cos #, and which are applied to two sets of perpendicularly arranged plates of a cathode-ray tube. The tube spot has a circular trace on which its positive corresponds to the angular position of plate 1 with respect to magnetic north. The switch 3, fixed with respect to the craft is closed once per revolution of plot 1 and causes extinction of the trace at a position corresponding to the craft heading.

Filed: 1921-01-10
Abstract: 157,974. Rialland, A. J. M. April 30, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Strainer separators.-A centrifugal separator for continuously clarifying liquids has two rotating surfaces a, b with a number of spiral passages e between them extending from the axis to the periphery and being open at each end. The wall d<2> of each passage is perforated and liquid is supplied through the centre pipe c and the separator is rotated. The liquid passes through the perforated walls d<2> and strikes the inclined unperforated walls d<1> ; it is thus deflected through the lower plate b and passes out by the pipe g. Any solid particles remain in the passages until they reach the periphery and then pass into the container h. A pipe p may introduce a liquid in the form of a jet or spray into the passages. In a modification the matter may travel from the circumference to the centre, and the container may rotate with the liquid while the separator remains stationary. In another modification the rotating surfaces may be conical; and in another modification the passages, instead of being spiral, may be straight and may project tangentially from a central tubular shaft.

Title: Preparation of platinum metal catalysts
Inventor: SPRAUER JEROME WILLIAM
IPC: B01J23/40
Filed: 1956-01-20
Abstract: In the manufacture of a platinum metal-on-alumina catalyst by impregnating activated alumina with a solution of a compound of a platinum metal and reducing the compound to metal, the activated alumina before impregnation is treated with an aqueous solution having a pH in the range 4 to 10 and containing at least one of the following oxidizing agents: water-soluble permanganates, pervanadates, permolybdates, monopersulphates, and perphosphates, hydrogen peroxide, ozone, sodium or other alkali metal peroxide, perhydrates, e.g. sodium perborate or sodium carbonate perhydrate, halogens (especially chlorine and bromine) and oxygen-containing halogen compounds having oxidizing properties, e.g. alkali metal and alkaline earth metal hypochlorites and hypobromites, hypochlorous acid, chlorine dioxide, and the alkali metal chlorites; after treatment of the alumina, the oxidizing agent is substantially completely removed.  The aqueous solution preferably contains 0.5-4 per cent by weight of the oxidizing agent and may be applied at a temperature above 50 DEG  C. for 0.2 to 2 hours.  The pH of the aqueous solution may be adjusted by addition of sodium bicarbonate or carbon dioxide.  When the oxidizing agent contains halogen, washing with dilute hydrogen peroxide is desirable before impregnation and reduction. Reduction may be effected with formaldehyde, formates, hydrazine, or hydrogen.  The activated alumina may constitute at least 50 per cent by weight of the catalyst support or may itself be supported on kieselguhr.  In Example I activated alumina is treated with an aqueous solution of sodium hypochlorite and sodium bicarbonate, washed successively with water and aqueous hydrogen peroxide to remove soluble salts, suspended in water saturated with carbon dioxide, and an aqueous solution containing palladous chloride and hydrochloric acid is added; the slurry is heated, mixed with aqueous formaldehyde to reduce the palladium salt, sodium bicarbonate to adjust the pH, and aqueous hydrogen peroxide to destroy any catalyst poison; the catalyst is then filtered, washed, and dried. In Example III hydrogen peroxide is used as the oxidizing agent in place of sodium hypochlorite.  In Examples V and VI the carrier is impregnated with platinum-palladium and palladium-ruthenium, respectively, using aqueous solutions containing chloroplatinic akcid and ruthenium chloride.  The catalysts are tested by use in the hydrogenation of 2-t-butylanthraquinone to 2-t-butylanthrahydroquinone.  The catalysts are useful in the production of hydrogen peroxide by alternately hydrogenating and oxidizing an alkylanthraquinone.ALSO:2-t-Butylanthrahydroquinone is formed by passing hydrogen into a solution of 2-t-butyl-anthraquinone in a mixture of methylnaphthalene and di-iso-butyl carbinol in the presence of a platinum metal on alumina catlyst, the alumina before impregnation with the platinum metal having been treated with an aqueous solution of an oxidizing agent (see Group III).
