Title: Method of operating a gas cooled nuclear reactor
IPC: G21C15/12
Filed: 1967-07-05
Abstract: 1,126,397. Nuclear power plant. GUTEHOFFNUNGSHUTTE STERKRADE A.G. 5 July, 1967 [9 Sept., 1966], No. 30912/67. Heading G6C. In a gas-cooled nuclear reactor, the gas flow is divided into two streams, one'of which flows directly through the core while the second passes over, and cools, the inner surface of the pressure vessel prior to entering the core. The two streams may enter and leave the pressure vessel through concentric ducts and the pressure vessel cooling gas may either enter the core after mixing with the first stream or enter the core separately. The heated gas passes from the reactor into a turbine, the exhaust from which heats the gas going to the core directly in a heat exchanger.

Abstract: 1,255,725. Altering physical structure; making silicon steel strip. GENERAL ELECTRIC CO. 19 June, 1969 [11 July, 1968], No. 31017/69. Headings B3A and B3V. Silicon steel strip having a substantially constant magnetic permeability is made by cold reducing below its recrystallization temperature a 2-3¢% Si steel strip having a preferred orientation. The grain oriented strip having a (110)[001] texture is formed by hot and cold rolling a strip, decarburizing it at 800‹ C. and annealing it in dry hydrogen at 900-1250‹ C. to effect secondary recrystallization. Alternatively, the strip is annealed by heating it in a reducing or neutral atmosphere at 950- 1050‹ C. for 5-60 mins. and then at 1175- 1250‹ C. for 1-30 mins. The grain oriented strip is finally cold-rolled 25-70% reduction in thickness to produce the desired magnetic properties.

Title: A method of measuring the bore of tubing
Inventor: MORTON GEOFFREY FISHER
IPC: G01B13/22
Filed: 1952-12-09
Abstract: 742,653. Electric measuring systems. DUNLOP RUBBER CO., Ltd. Nov. 11, 1953 [Dec. 9, 1952], No. 31138/52. Class 40(1) [Also in Group XIX] The bore of a length of tubing is measured by supplying air at constant pressure through a constriction to one end of the tubing, inserting a, magnetic ball in the other end of the tubing to form a second constriction, and continuously measuring the air pressure in the tubing between the two constrictions as the tubing is moved relative to the ball which is held stationary by a magnetic field. The pressure is a measure of the bore at the position of the ball and may be recorded against tube position, the record being graduated if desired to read the bore directly. A water manometer may measure the air pressure when the bore of rigid lengths of non ferrous or glass tubing is under test, but for flexible rubber or like tubing an electrical method is essential. As shown a magnet 20 maintains the ball 21 stationary in flexible tubing T as the tubing is wound on to a turntable 17 from a turntable 10. The turntable 10 rotates with a tube 14 dipping into a trough 15 of mercury. Air from a constant pressure source is fed by a tube 16 past a constriction 22 through the tube 14 to the corresponding end of the tubing T, and the pressure variations between the two constrictions are translated by a bellows 24 into corresponding variations of a capacitor 24a, 25 which are measured and recorded at 26 relative to tubing position.

The spacer means need not be bonded to the outer cover, the flexibility of the cable thus being improved. The insulation is provided by layer 5 while the dust-free air prevents corona discharge at the surface of layer 5.

Title: A process for improving the properties of natural waxes
IPC: C11C3/12
Filed: 1931-11-11
Abstract: Vegetable or animal ester waxes are improved in colour, iodine value, melting-point content of unsaponifiable matter, and solubility in turpentine or other solvent, by reacting the warm liquefied or dissolved wax in presence of a hydrogenating catalyst with hydrogen under at least 50 atmospheres pressure so as to reduce the saponification value at most by 15 per cent.  Waxes specified are carnauba, candelilla, bees, and shellac waxes. Catalysts are copper, zinc, silver, and nickel or/and cobalt, usually on carriers such as kieselguhr, pumice, silica gel or active carbon, and may be activated as by tungsten, molybdenum, vanadium, chromium and/or potassium. Solvents specified are hexahydro-benzene, hexahydro-toluene, decahydro-naphthalene, petroleum fractions such as ligroin, and aromatic hydrocarbons, e.g. benzene or toluene.  Temperatures of 120-250 DEG  C., and pressures of 100-300 atmospheres are usually employed.  In one example, 600 kg. of beeswax is mixed with 50 kg. of a catalyst consisting of 80 parts of kieselguhr and 20 parts of nickel obtained by reducing nickel carbonate at 400 DEG  C. with hydrogen; the mixture is treated with hydrogen for 2 hrs. at 200 DEG C. and 150 atmospheres in a stirring autoclave.  A shoe cream or floor polish is obtained by mixing 5 kg. of the treated beeswax with 5 kg. of ozokerite, 10 kg. of paraffin wax, and 70 kg. of oil of turpentine.
