Abstract: 963,216. Voltage modifying arrangements. MICAFIT A.G. Nov. 10, 1960 [Dec. 7, 1959], No. 38625/60. Heading H2H. The capacitance on the earthed side of a capacitive voltage divider C 1 , C 2 , C 3 , which is connected to an inductive medium-voltage circuit to provide a capacitive voltage transformer, is made up of two condensers C 2 , C 3  in series, with a self-quenching spark gap F in parallel with one of them. The medium voltage circuit comprises a transformer T, with or without a choke L 1  in series therewith. R 1  represents the loss resistance of choke and transformer. The arrangement prevents the development of an undesirable state of oscillation associated with high voltages and leading capacitive currents. Resistances or chokes may be connected in series with the spark gap. The advantages of an arrangement in which the capacitor stack is mounted on a casing carrying the medium voltage circuit and the spark gap are discussed, and a mathematical analysis is included.

Abstract: 1,209,941. Alkylating isoparaffins; dehydrogenation; isomerization. SUN OIL CO. 22 Aug., 1967 [25 Aug., 1966], No. 38631/67. Heading C5E. C 4 -C 6  isoparaffins having a tertiary carbon atom are alkylated with a C 3 -C 6  mono-olefin at a temperature below the critical temperature of the lower boiling hydrocarbon and at a pressure such that the reactants are in the liquid phase in the presence of a substantially anhydrous crystalline alumino-silicate zeolite, and the reaction is stopped before the weight rate of production of unsaturated hydrocarbon becomes greater than the weight rate of production of saturated hydrocarbon. Preferably the rate of olefin addition is controlled so that the amount of unreacted olefin in the reaction mixture is less than 12 mole per cent based on the unreacted C 4 -C 6  isoparaffin. A halide promoter having a molecular cross-section of less than 9 €, selected from HF, HCl, HBr and saturated halohydrocarbons may be present in the reaction mixture in amount 10-<SP>5</SP> to 10-1 moles per mole of isoparaffin reactant. Examples describe the alkylation of isobutane with isobutene, butane- 2, butane-1 and 2,3-dimethylbutene. Liquid mixtures of hydrocarbons are claimed per se which contain less than 1 % by wt.of unsaturates and which comprise at least 60 mole per cent of C 8  paraffin, the paraffin consisting of less than 1À5 mole per cent methylheptanes, 5-20 mole per cent dimethylhexanes and 80-95 mole per cent trimethylpentanes, the said trimethylpentanes comprising less than 30 mole per cent 2,2,4-trimethylpentane. Under the conditions of the alkylation it is found that butene-1, in the presence of n-butane, isomerizes to cis and trans butene-2. Lower paraffins such as C 5  and C 6  paraffins can be separated from the higher paraffins in the alkylate product and dehydrogenated using a fixed bed catalyst of Pt-Al 2 O 3 , Ni-SiO 2 , Ni- MgO, Ni-A1 2 O 3 , Cu-A1 2 O 3  or Cr 2 O 3 -A1 2 O 3  to give mono-olefins mixed with unreacted paraffins which may be used as a feed in the alkylation. The zeolite may have an atomic ratio Al/Si of 0À65 to 0À35 and contain at least one cation comprising a rare earth metal, preferably cerium.

Title: Improvements in and relating to gramophones and the like
IPC: G11B17/02
Filed: 1929-12-18
Abstract: 344,561. Gramophones. BILANTZ, D. S., 58, City Road, and WATTS, P. T., 10, Queen Adelaide Road, Penge, both in London. Dec. 18, 1929, No. 38822. [Class 40 (ii).] An automatic stop for gramophones and the like comprises lever members 9, 10 actuated by the traversing movement of the tone arm, and a member 16 which is adapted d intermittently to cause separation of the levers during the playing of a record and also to effect a greater separation of such levers, resulting in the application of brake mechanism, upon an increase taking place in the rate of movement of the tone arm. The levers 9, 10 are pivoted together at 12<1>, and are capable of movement about a fixed pivot 13, the lever 9 having only a loose connection at such pivot. A spring 12 acts to maintain the levers in engagement with a depending pin 11 on the tone arm so that the levers move with the tone arm about the pivot 13. The lower end of the lever 10 is provided with a serrated surface 17 engaged by a projection 18 on a spring-controlled detent lever 16. A cam member 20 rotating with the turntable spindle engages a projection 21 on the detent lever 16 so as to cause the latter to reciprocate about its pivot and intermittently disengage the projection 18 from the surface 17. The lever 10 will be separated from the lever 9 during each period of engagement of the lever 16 and surface 17, and will follow up the lever 9 under the action of the spring 12 during the disengaged periods. At the end of playing a record, the lever 9 receives an increased movement from the tone arm and, since the lever 10 is restrained by the lever 16 from movement, the lever 9 moves about the pivot 121 so that a projection 14 on such lever engages an arcuate surface 15 on a brake-releasing lever 3 which thereupon allows a spring-controlled brake lever 2 to move to stopping position. Normally the brake lever 2 is held in the " off " position by the engagement in a notch 4 in the lever 3 of a projection 5 on the brake lever 2. An arcuate surface 23 on the 'lever 16 terminates in a cam 24 which is engaged by the end of the brake lever 2 when the brake is applied so as to release the lever 10 from engagement with the lever 16. During resetting of the brake, a surface 25 on the lever 10 engages the lower end of the brake lever 2 until the projection 5 engages the notch 4 in the lever 3, Instead of a serrated surface 17 on the lever 10, there may be provided a wedge-shaped contacting surface on the detent lever and a groove on the lever 10, or a pad of rubber &c. may be provided on one member and a roughened or serrated surface on the other. The projection 14 on the lever 10 may be adjustable.

Title: Graphite coating of fuel particles
IPC: G21C3/62
Filed: 1962-10-19
Abstract: Nuclear fuel particles, e.g. U or Th oxides or carbides, are coated with pyrolytic graphite by the thermal decomposition of a hydrocarbon gas in the presence of the particles to be coated at a temperature between 1500 DEG  and 3000 DEG C. and a pressure of between 1 mm. and 200 mm. of mercury.  For example, 30 gm. of uranium dicarbide in the shape of spherical particles of diameters between 177 and 250 microns are charged into a hollow graphite cylinder which is filled with argon at a pressure of 20 mm. of mercury and rotated about its longitudinal axis at a speed of 30 r.p.m. while its temperature is raised to 1700 DEG  C. by means of a surrounding induction coil, methane being introduced into the cylinder at a rate of 0.2 litre/min.  After 4 hours of processing, the methane supply is shut off and the cylinder allowed to cool to room temperature, the particles then having a graphite coating of average thickness about 80 microns. The nuclear fuel particles are kept in constant motion, e.g. by one or more rotating blades or wipers, or by suitably vibrating the container holding the particle charge. Alternatively, fluid bed or moving bed techniques may be employed.

Title: Process for the separation of krypton and xenon from mixture with oxygen
Inventor: ARMOND JOHN WALTER
IPC: F25J3/04
Filed: 1959-11-23
Abstract: Krypton and xenon are separated from oxygen by contacting the mixture with a downwardly moving bed of granula adsorbent at -90 DEG C. to the liquefication temperature and allowing the bed to enter a subjacent rectification zone where, optionally aided by an oxygen purge, the krypton and xenon are preferentially desorbed. The bulk of the oxygen is not adsorbed and a portion thereof may be recycled to the foot of the rectification zone to lift the adsorbent externally to the top of the adsorber, a minor amount of oxygen being bled into the rectification zone as purge.  According to an example, oxygen containing 620 p.p.m. krypton and 46 p.p.m. xenon was fed to an adsorption zone maintained at -183 DEG C. down which granular silica gel gravitated to a rectification zone below.  The latter operated at 100 DEG C. and the apparatus pressure was atmospheric.  If desired the initial oxygen mixture may be fed to the adsorber as a liquid and evaporate therein.  Other adsorbents specified are active charcoal, alumina, silica-alumina, sepiolite and natural zeolites or synthetic zeolites described in Specifications 777,232 and 777,233.

Abstract: 974,341. Wood pulp treating apparatus. DEFIBRATOR A.B. Nov. 18, 1960 [Nov. 20, 1959], No. 39672/60. Heading D2W. An apparatus for obtaining cellulose pulp from, for example, a ligno-cellulose containing or a fibrous vegetable material, comprises a vertical tower up which the material dispersed in a liquid is caused to travel by a helical screw conveyer which is coaxial with the tower has a length which is a small fraction of the height of the tower and is mounted in the lower portion of the tower so that the material can be caused to travel up the tower during the major part of its travel without direct contact with the conveyer. As shown in Fig. 1, wood chips preheated by steam in the pipe 10 are conveyed by a screw feeder 28 from the bottom 7 the pipe 10 to the bottom of a tower 30 and highly compressed in a known manner in a plug forming tube 31 en route to the tower 30. The bottom if the tower is provided with a helical screw 42 (Figs. 1 and 3) mounted on a shaft 40 driven by a motor 38 through a level gear 39. The tower 30 is of circular cross-section which increases slightly in the upward direction. The length of the screw 42 is not greater than the inside diameter of the surrounding part of the tower and the pitch of the screw is equal to half this diameter and is preferably about twice the diameter of the inlet 44 at the bottom of the tower. A solution of a chemical treating agent is fed into the bottom of the tower 30 through a tube 46 and reaches a level in the tower controlled by the level regulators 48 adjustable vertically on guides 50. The treated chips are conveyed from the top of the tower 30 to the top of a cooker 56 by a screw conveyer 56. When the chips which have been strongly compressed in the tube 31 enter the bottom of the tower 30, which is at a lower pressure, the chips expand and the treating liquor 5 sucked into their pores. In a modified form of the apparatus tannins may be extracted from the wood chips at the same time that cellulose pulp is produced.
