Title: Improvements in or relating to the Manufacture of Articles of High Density Polycrystalline Refractory Oxide Material
Inventor: BATES CARL HOBART
IPC: C04B35/111
Filed: 1967-05-31
Abstract: 1,175,887. Refractory oxide materials. GENERAL ELECTRIC & ENGLISH ELECTRIC COMPANIES Ltd. 14 May, 1968 [31 May, 1967], No. 25026/67. Heading C1A. High density, light-transmissive polycrystalline material is produced by shaping one or more finely-divided hydrated refractory oxides into a coherent form, heating to dehydrate the oxide or oxides and form a porous body, which is then impregnated with a fluid containing cations of Mg, Zn or Li in an amount such that the weight of cations is less than 1% of the weight of the oxide(s), and heating the impregnated body in a reducing atmosphere at more than 1000‹ C. so as to sinter the material. The refractory oxide may be alumina, magnesium oxide, thorium oxide, yttrium oxide or one or more rare earth metal oxides. In the described case of alumina, gamma-Al2O3.H2O, alpha- Al2O3.H2O, alpha-Al2O3.3H2O or gamma-Al2O3.3H2O (British nomenclature) may be formed into a desired shape and heated at less than 1000‹ C. to a transitional form of anhydrous alumina (preferably 800-1000‹ C. when alpha-Al2O3 is used), which is then impregnated with cations of Mg, Zn or Li in the form of a water-soluble salt which decomposes on heating to give the oxide, and sintered at above 1550‹ C, upon which alpha-Al2O3 is obtained. The reducing atmosphere may be of moist hydrogen. The hydrated refractory oxides may be formed into a coherent shaped body by hydrostatic pressing in a suitably shaped deformable mould. For forming a tube, the oxide may be packed round a mandrel within the mould. In the case of alumina, the shaped body may be dehydrated by heating at 400-500‹ C. for 2-5 hours and sintered at 1650-1900‹ C. The hydrated oxide may be formed into a shaped body by converting the oxide to a viscous colloidal sol, possibly by dispersal in a dilute acid, and extruding the sol to form a rod or tube and drying in air to cause gelling of the sol. Such a rod of alumina may be dehydrated by heating at 100‹ C., and sintered at 1550-1800‹ C. An electric discharge envelope for a discharge lamp may be formed from alumina by the process of the invention.

IPC: H03F3/02
Filed: 1929-08-22
Abstract: 317,800. Siemens & Halske Akt.- Ges. Aug. 22, 1928, [Convention date]. Thermionic amplifiers.-To prevent saturation of the core of the coupling-transformer U, the plate supply of the valve VI is fed through a resistance Ra separated by a blocking-condenser Ca from the primary winding of the transformer. The secondary winding of the transformer is similarly shielded from pre-magnetization by the grid current of the amplifier V2 by interposing another blocking-condenser Cg between that winding and the grid-leak Rg. The resistance Ra is of the same order as the internal resistance of the valve V1, and being considerably larger than the resistance of the common high-tension battery prevents undesirable back-coupling. The grid resistance Rg also serves to damp out peak voltages tending to destroy the initial magnetization of the core.
Patent GB-637130-A (GB)
Title: Process for the manufacture of pyridine compounds
Filed: 1947-09-20
Abstract: 3-Pyridinethiol hydrochloride is prepared from 3-pyridinesulphochloride by reduction with stannous chloride, and treatment of the resultant stannic chloride double salt of 3-pyridinethiol hydrochloride with a reagent capable of precipitating the tin as its sulphide, e.g. sodium sulphide.  The stannous chloride is preferably used with hydrochloric acid. 3-Pyridinethiol is prepared from the hydrochloride by treatment with alkali.  The hydrochloride may be treated with metal halide to form double salts, or with metal salts, e.g. zinc chloride, in the presence of a binding agent, e.g. sodium acetate, to form the metal (e.g. zinc) mercaptide of 3-pyridinethiol.  Zinc may be replaced in the reaction by, for example, mercury, gold, cadmium, bismuth, iron, lead, copper, or alkali metals, e.g. calcium or sodium.  The zinc mercaptide treated with hydrochloric acid gives the corresponding zinc chloride-thiolhydrochloride double salt. In the examples: (1) 3-pyridinesulphochloride hydrochloride is reduced with stannous chloride to give the stannic tetrachloride double salt of 3-pyridinethiol hydrochloride; (2) this double salt is treated with sodium sulphide to give a solution of the hydrochloride, reaction of which with zinc chloride and sodium acetate gives the zinc mercaptide of 3-pyridinethiol; (3), (4), (5) the mercury, cupric, and bismuth mercaptides are similarly prepared; (5) and (6) the bismuth chloride and zinc chloride double salts of 3-pyridinethiol hydrochloride are prepared.  The Specification as open to inspection under Sect. 91 discloses the preparation of 3-pyridylthioglycollic acid by addition of the tin tetrachloride double salt of 3-pyridylthiol hydrochloride to aqueous sodium monochloroacetate containing caustic soda, followed by acidification to pH 4.5; an example is given.  This subject-matter does not appear in the Specification as accepted.ALSO:3-Pyridinethiol, and its salts, e.g., hydrochloride, its double salts with metal halides, e.g., with stannic chloride, and its metal mercaptides, e.g., <FORM:0637130/VI/1> are used as fungicides and bactericides for application to the skin, preferably when incorporated with carriers such as talc, magnesium silicate, lanoline, petroleum jelly, or a high molecular weight hydroxy animal fat.

Abstract: 802,805. Nuclear reactors. BABCOCK & WILCOX, Ltd. Aug. 23, 1956 [Aug. 26, 1955], No. 25740/56. Class 39(4). A fuel element for a nuclear reactor comprises a bar of fissile or fertile material enclosed in a sheath, the cross-sections of the bar and sheath being such that the sheath is only partly filled by the bar, and spacing means such as bosses, ribs or distance rings are arranged to prevent contact between the bar and the wall of the sheath or to limit the contact to that occurring at spacing means provided on the bar. In Fig. 3 a bar 1 of uranium, plutonium or thorium is supported within an aluminium sheath 2 by longitudinally spaced groups of circumferentially distributed radial pins 5 provided either on the bar or on the sheath. In another arrangement, Fig. 4, distance rings 6 are provided on the bar and annular recesses 8 are formed on the bar in the vicinity of the rings 6 to prevent any increase of neutron flux near the rings. The spacing means are preferably formed of non-fissile or fertile material having a melting point higher than that of the bar or of the sheath. In a further arrangement, Fig. 5 (not shown), the spacing means are of moderating material, e.g., graphite, in the form of semi-circular parts which fit into annular grooves formed in the bar. By spacing the bar from the sheath the danger of a high pressure within the sheath due to the generation of gaseous fission products is reduced.
