Title: Improvements in or relating to well tools
IPC: E21B33/14
Filed: 1948-09-08
Abstract: 652,469. Well cementing &c. tools. McGAFFEYTAYLOR CORPORATION. Sept. 8, 1948, No. 23632. Convention date, Sept. 26 1947. [Class 85] Secured to a drill rod 3 by a collar 4 is a washing and cementing tool which comprises a tubular body 1 open at the lower end 12 and closed at the upper end 14 and having positioned thereon two packers 5, 6 which engage the casing 2 to seal off a chamber 7. The cups 8 of the lower packer 6 allow upward flow of fluid, but the cups 9, 10 of the packer 5 prevent flow in either direction. Ports 13 are provided in the body 1 above the packer 10, and a packer 15, which prevents downward flow, is positioned above the ports 13. A pipe 18 connects the drill rod 3 to the upper part of the chamber 7 and a pipe 21 connects the lower part of this chamber to the space between the tool and the casing above the packer 15. A valve 17 covers either ports 13 or ports 16 which also connect the interior of the body 1 with the space surrounding said body above the packer 15. During lowering, fluid below the tool passes freely upwards through the body 1 out through the ports 13 and past the packer 15, at the same time a portion flows past the cups 8 into the chamber 7 and thence through pipe 18 and drill rod 3 as well as through pipe 21 into the space between the body 1 and the casing, since the valve 17 is covering the ports 16 and not the port 23. To test for leakage, the top of the casing is closed down and pressure increased on the fluid in drill rod 3, pipes 18, chamber 7, pipe 21 and in the casing above the packer 15, a drop in pressure indicating that a leak has been passed by the tool. Prior to cementing, the tool is below the perforated zone of the well casing and fluid for cleaning purposes is pumped through the passages as enumerated when testing for leakage, the casing head now being open. For cementing, the tool is raised so that the chamber 7 straddles the perforated zone 2a, the valve 17 closes the port 23, and the cement travels down the drill rod 3, pipe 18, chamber 7 and out through the perforations. After this cementing process, the tool is washed out by pumping cleaning fluid down the casing, through the now open ports 16, body 1, up past packer 6 into chamber 7, and thence to drill rod 3 by pipe 18. Alternatively the tool may be lowered so that the valve 17 closes port 16 and opens port 23, the cleaning fluid then proceeding from pipe 3 through pipe 18 to chamber 7 to be returned by pipe 21 to port 21. The fluid may, however, flow in the reverse direction. During raising, well fluid above the packer 15 passes to below the tool through ports 16 and the bore of the tool. Specification 630,771 is referred to.

Title: Improvements in or relating to precipitating chemical compounds on an incandescent body and of isolating the said chemical compounds
IPC: F24H3/00
Filed: 1924-10-10
Abstract: 223,244. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. Oct. 11, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Enamelling.-Chemical compounds are formed as a coating upon incandescent bodies such as wires or rods to make filaments such as cathodes for thermionic valves, X-ray tubes and the like by heating the wire or rod in an atmosphere containing a volatile halogenide of the positive element of the compound to be formed and one or more gases containing the negative element of the compound required or a compound of such element with or without a reducing gas such as hydrogen, a hydrocarbon, or carbon monoxide. The compounds obtained may be removed from the wire or rod if desired. The compounds mentioned as being obtained by this process are nitrides, such as zirconium, titanium, niobium, vanadium, and boron nitrides, phosphides such as zirconium phosphide, carbides such as tantalum and molybdenum carbides, borides, silicides, selenides, carbo-nitrides, and oxides such as tin oxide. The process may be effected in an apparatus comprising a tube 8 containing the wire 12 which is to be coated, the wire which may be of nickel, tungsten, molybdenum or platinum, being heated to a suitable temperature such as 1000-2000‹ C. by means of an electric current supplied through leads 10, 11. A reducing gas such as hydrogen is led in through a pipe and is cooled to remove impurities in a tube 2 surrounded by liquid air in a vessel 3. The cooled hydrogen passes through a vessel 5 containing the volatile halogenide, which is heated if necessary, and the mixture then passes into the tube 8 through perforations in a tube 7. The exit gases pass out through a perforated tube 13 and are freed from excess of halogenide in a tube 14 cooled by liquid air. There may be more than one vessel 5 when more than one halogenide is used, and' the reducing gas may pass through them all in parallel. Examples describe the production of zirconium, titanium, niobium, vanadium and boron nitrides from nitrogen, hydrogen, and zirconium, titanium, or niobium chlorides, vanadium oxychloride, and boron bromide respectively; zirconium phosphide from hydrogen, zirconium chloride, and phosphorus trichloride or hydrogen and a compound of phosphorus pentachloride with zirconium chloride, 2 Zr Cl4PCl5, tantalum carbide from tantalum pentachloride and hexachlorethane or a mixture of carbon monoxide and hydrogen; molybdenum carbide from molybdenum pentachloride and carbon tetrachloride with or without a carrying gas such as hydrogen or argon; tin oxide from air and tin chloride; and carbonitrides or a mixture of carbides and nitrides from cyanogen and halogenides.

Title: Improvements in or relating to heating systems employing a circulating liquid heat carrier
IPC: F24D3/10
Filed: 1934-08-21
Abstract: 443,370. Heating by circulation of fluids. FARRER, J. O., 27, Chancery Lane, London, and KOCH, E. A. J., 64, Victoria Street, Westminster. Aug. 21, 1934, No. 24155. [Class 64 (ii)] A heating system, operating at a pressure above atmospheric and employing a liquid which fills the circulation pipes, includes a relatively small closed expansion vessel and means permitting the flow of liquid to or from the system when the volume of the liquid falls below or rises above predetermined values. In one arrangement, comprising a water heater 1, Fig. 1, of the drawings accompanying the Provisional Specification, constituting the expansion vessel, a circulating pump 22, and flow and return pipes 21, 12 respectively between which are connected a heat consumer 23 and a pipe 18<a> permitting water to pass from the return to the flow pipe, the water level in the heater effects through a float 2 and linkage the position of a piston valve 7 controlling the flow of water to or from an open tank 13. During the initial heating of the system, the water level rises and effects an upward movement of the valve thus permitting water to pass through the pipes 25, 26 from the system to the tank, while when the system is closed down the water cools and the level falls, thus effecting a downward movement of the valve and the supply of water by the pump 14 from the tank 13 to the system. A non-return valve 17 permits water to pass from the tank 13 into the system if the pump is inoperative during cooling and the pressure in the system falls below atmospheric. The small changes in volume occurring during the operation of the system are not sufficient to move the valve 7 to permit the flow of water either to or from the system. In another arrangement, the position of the pivot point 5, Fig. 2, of the linkage is controlled through links 5<a>, 11<a> by the pressure in the generator and the temperature may be maintained constant by admitting water from the return pipe to the flow pipe.
