Patent GB-176105-A (GB)
Abstract: 176,105. Guy Motors, Ltd., and Buckney, E. J. D. Nov. 26,1920. Fuel containers.-In liquid-fuel-supply systems for motor vehicles wherein a reserve supply of fuel is left in the tank for use in case of emergency and two tubes of different length extend from a valve-fitting into the tank, the valvefitting for determining which supply is in use consists of a single one-way cock of ordinary type. In the case where fuel is removed from the tank by suction or pressure, the single cock 16, Fig. 1, is placed between the upper ends of the usual long and short pipes 3, 4 of which 3 is always open to the fuel outlet pipe 8. The cock is supported by a fitting 6 cast with a cover plate 9 secured by bolts 13 and lugs 12 to a flanged ring 11 riveted to the tank. The cock is actuated by a handle 14 having a spring detent to retain it in position. Normally the cock is open and fuel is supplied through both pipes 3 and 4. When the main supply is exhausted by the level falling below the pipe 4, the cock is closed and reserve supply drawn through pipe 3 only. In this closed position the handle 14 comes over the filler cap so that the tank cannot be filled with the cock in its closed or reserve position. Where the fuel leaves the tank by gravity, the cock 16, Fig. 4, is normally closed and is open when the fuel level falls below the top of the pipe 3 for the main supply. The handle 14 works over a plate marked to indicate which supply is being drawn upon.

Title: Improvements in synthetic gem bodies and their manufacture
IPC: C30B11/10
Filed: 1944-09-20
Abstract: 581,619. Synthetic gems. LINDE AIR PRODUCTS CO. Sept. 20, 1944, No. 17914. Convention date, Sept. 21, 1943. [Class 43] Synthetic gem rods, from which jewel blanks may be made, are produced by melting the gem material and allowing it to crystallize on a seed gem (which may be part of a previously made rod) positioned so as to produce any desired crystallographic orientation in the gem rod which results as the process is continued. The powdered gem material, such as alumina powder or alumina powder with 8 to 28 per cent. magnesia, is sifted from the container 15 through a sieve 16 and carried into the central passage 21 by oxygen supplied through the pipe 11. Hydrogen passes into the burner 23 through the conduit 25, and burns in the oxygen. The material is melted and accumulates on a gem seed embedded in a ceramic pedestal 28 to form a rod 30 which is gradually moved down by the rack and pinion gear 31, 32. The orientation of the crystal may change gradually throughout the length of the rod, but the change is confined between upper and lower limits by stopping the growth of the rod when the desired limit of orientation is reached. When producing white sapphire (clear corundum) the change of orientation along the rod is small compared with the change when producing ruby (red corundum). Rods of synthetic spinel may also be grown by this method. A high degree of roundness and mechanical strength is present in spinel rods containing crystal twins.

Title: An improved method of forming an adherent layer on a ceramic material
Inventor: BARRETT PHILIP CECIL
IPC: C04B41/89
Filed: 1957-06-06
Abstract: An adherent layer is formed on a ceramic member by coating the ceramic with a powdered refractory material containing a minor proportion by weight of an active metal, selected from titanium, zirconium and hafnium and heating in a non-oxidising atmosphere to a temperature below the ceramic maturing temperature.  The active metal must be included in a form such that the specified heating causes it to secure the refractory material to the ceramic, e.g. it may be a hydride but not a carbide.  The refractory material may be e.g. molybdenum, a molybdenum-manganese, or an iron-tungsten mixture, or it may be a carbide or mixture of carbides, together with the active metal.  A preferred mixture comprises by weight 67% tungsten carbide, 23% titanium carbide and 10% titanium hydride.  Suitable ceramic compositions, and details of preparation, coating and heating are given.  A second refractory coating without an active metal additive may be applied and this may be of similar materials to the first or may be e.g. 95% molybdenum and 5% molybdenum oxide.  After the application of one or both coatings the ceramic member may be bonded to a metal member e.g. of nickel-iron alloy, by first sintering on to the coated ceramic a layer of powdered nickel or similar metal and then brazing the metal member to this with e.g. a silver-copper entectic solder.

Title: Manufacture of androstene-17-ol-ones and derivatives and substitution products thereof
IPC: C07J75/00
Filed: 1940-12-23
Abstract: 550,684. Androstene - 17 - ol - ones. SOC. OF CHEMICAL INDUSTRY IN BASLE. Dec. 23, 1940, Nos. 18026 and 18027. Convention dates, Dec. 23, 1939 and Nov. 1, 1940. [Class 2 (iii)] Androstene - 17 - ol - ones, their esters or ethers or derivatives thereof substituted in the 17 - position are prepared by treating an androstene - 17 - one containing in ring A or B a double linkage but no nuclear substituent with a mild reducing agent or metal hydrocarbon compound adapted to convert the 17 - CO - group into a - CR(OH)- group without attacking a nuclear double linkage and then oxidizing by treatment with chromic acid, selenium dioxide or a lead tetra-acylate to introduce oxygen or a group containing oxygen into an α-position to the double linkage. If necessary prior to the oxidation the hydroxyl group is protected by esterification or etherification. The final product may if desired be hydrolysed. As esterifying or etherifying agents suitable to protect the double bond there may be used aliphatic acids such as formic, acetic, propionic, nbutyric, isobutyric, n-valeric, iso-valeric, caproic, capric, palmitic, or stearic acids, or an aromatic, fatty-aromatic, or inorganic acid such as benzoic, cinnamic or a substituted carbonic acid. Etherification may be conducted with a phenol, or with an aliphatic or aliphaticaromatic alcohol, such as methyl, ethyl or benzyl alcohol or a tri-aryl-methyl carbinol. In examples (1) # <SP>4</SP>-androstene - 17 .- one is reduced by hydrogen in the presence of a nickel catalyst, the product esterified by propionic anhydride to give #<SP>4</SP>- androstene - 17 - ol - propropionate which is then oxidized with chromic acid in glacial acetic acid to give # 4- androstene 3 - one - 17 - ol - propionate in addition to the corresponding 6 - oxo and 3 : 6 - dioxo compounds which are also produced. The reduction step may if desired be carried out by means of an alkali metal and an alcohol, by an organometallic compound such as isopropyl magnesium iodide or by a bio-chemical or electrochemical method (2) #<SP>4</SP> - androstene - 17 - one is reduced by treatment with an ether solution of methyl magnesium iodide to give #<SP>4</SP>-17-methylandrostene - 17 - ol, which is then oxidized to 17 - methyltestosterone in a manner similar to that used in example (1), or it may be converted by the action of selenium dioxide or a lead tetra-acylate into #<SP>4</SP>-. 17- methylandrostene - 3 : 17 - diol which may then be converted by oxidizing or dehydrogenating agents into 17 - methyl - testosterone. Specification 550,478 is referred to. The Specification as open to inspection under Sect. 91 includes quite generally the use of any reducing agent which is adapted to convert - CO - group into a -CH(OH)-group, and also the use in the second stage of the process of any oxidizing agent. This subject-matter does not appear in the Specification as accepted.
