Title: Process for the preparation of cyclic polyolefinic hydrocarbons
IPC: C07C5/05
Filed: 1965-05-24
Abstract: The partial hydrogenation of cyclic polyolefins to mono-olefins is effected in the presence of water and a palladium or palladium compound catalyst.  The catalyst may be a divalent salt of palladium or a p -bonded olefin complex in solution or on a support in an amount of 0.1-5% based on hydrocarbon and calculated as metal.  The amount of water may be 50-150% by weight of hydrocarbon and there may also be present up to 40% by weight of the water of a polar water-miscible solvent, e.g. dimethylformamide, dimethyl sulphoxide or piperidine. Inert solvents may also be present. Reaction is effected at 25-150 DEG  C. and 1-100 atmospheres for a time until the hydrogen consumption is the theoretical requirement.  The reduction of cyclododecatriene and cyclooctadiene are exemplified.

Abstract: 935,464. Nuclear fuel elements. GENERAL ELECTRIC CO. Ltd. June 4, 1962 [June 19, 1961], No. 22043/61. Class 39 (4). [Also in Group XIII] A protective can for a nuclear fuel element has longitudinal fins or splitters 6 radiating from its surface to define separate flow passages A, B, C and D for the throughflow of cooling fluid, heat-exchange fins 5 also radiating from the surface of the can but to a distance less than that of the splitters 6 and being inclined to the general direction of coolant flow through the passages, partition plates 7 extending longitudinally of the passages and lying in a cylindrical surface defined by the tips of the fins 5, the plates 7 being spaced from the splitters 6 to provide openings 8 through which cooling fluid can pass to and from the fins 5, and baffle members 9 extending transversely between and radially as far as the splitters 6, the members 9 being inclined to the general direction of coolant flow through the passages at an angle equal, but of opposite sign, to the angle of inclination of the fins 5. The fins 5 may be formed integrally with the can and extend as helical members longitudinally of the can or be of herring-bone formation so that the fins in adjacent passages are inclined in opposite directions. The cooling fluid is caused to follow a plurality of paths in which it flows alternately between the fins 5 on one side of a partition plate 7 and between the baffle members 9 on the other side, undergoing a change in direction as it impinges upon the splitters 6. In order to minimize the overall impedance to coolant flow, the areas of the openings 8 should preferably equal the crosssectional areas of flow on both sides of the partition plates 7. The splitters 6 referred to above are straight but in certain arrangements it may be advantageous for them to be helical, in which ease the fins 5 may be straight, annular or helical and positioned so that they are inclined to the general direction of coolant flow through the resulting helically extending passages.

Title: Improvements in or relating to desiccation, more particularly to desiccation of substances of organic origin
IPC: A23C1/08
Filed: 1924-09-22
Abstract: 222,154. Tival, H. L. P., and Descombes, F. A. Sept. 22, 1923, [Convention date]. Drying at particular temperatures and pressures.-Solid and liquid substances to be desiccated are frozen, ground to a powder, and fed into a vacuous chamber which is maintained at a low temperature, the powder being deposited, as a film, upon an electrified endless band which asses into a second vacuous chamber wherein the moisture in the powder is evaporated and caused to deposit upon a sphere which is maintained at a low temperature. The powdered material is fed bv an air-tight rotatable valve into a shoot f from which it is discharged, in the form of a mist, into the vacuum chamber c by a rotary brush g, oppositely rotating brushes h in the lower part of the chamber assisting the deposition of the powder upon the electrified endless band m which is connected with a source of high potential, a wire j stretched across the chamber being connected with a source of low potential. The endless band with its deposit of powder passes over rollers b in a second vacuum chamber, and the dried product is removed from the band by rotary brushes n and falls into a shoot l from which it is discharged by a rotatable valve w. The moisture evaporated from the powder condenses upon the metal sphere o, which is supplied with liquid oxygen to maintain a low temperature in the apparatus, becomes frozen thereon, and is removed by a rotary scraper r, the ice falling into the tube t from which it is discharged by a rotatable valve. A vacuum is maintained in the apparatus by means connected with the pipe x. Electric heating elements a<3> may be arranged between the rollers b, and the electrification of the band may be maintained by substituting for the rollers b electric condensers of a rotary type or by arranging plate condensers between the rollers. In a modification, the brushes h are replaced by a pair of cylinders which assist in the pulverization of the material.

Abstract: 626,654. Radio navigation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 26, 1946, No. 22378. Convention date, Nov. 29. 1941. [Class 40 (vii)l In a radio-navigation arrangement wherein pulses of energy are radiated in a predetermined time relation from a plurality of known locations and the receiver includes a cathode-ray tube timing device means are provided for blanking the ray from the screen except during a selectable interval which may be set to include the deflection indication of a received signal. The position indicating system may be similar to that described in Specification 626,647 and include a decade timing indicator comprising cathode-ray tubes 11, 13 and 15 with circular time-base traces controlled by 50 kc. oscillator 17 which is synchronized with the incoming pulses from one of the transmitters. The output of the frequency division chain 27, 35, 43, 45 at the received pulse recurrence frequency is applied to an unblanking circuit 65 which may be adjusted to unblank the indicators only during the interval containing a desired received pulse. This is particularly important with the high angular velocity indicator 11 on which a given deflection only occurs once during severalthousand scanning revolutions and the relative intensity of the deflection would therefore be extremely weak under normal circumstances. Circuit 65 includes switches 67, 69, 71 for connecting adjustable resistors 73 or 75 or short circuit 74 across circuit elements to vary the timing of the unblanking pulse. The switch 69 is first closed and if the unblanking circuit is correctly adjusted the zero of the traces will be visible including the deflections caused by the incoming pulses controlling the master oscillator. On substituting switch 67 the resistors 73 may be adjusted to cause the pulses from one of the other transmitters to be displayed and similarly with switch 71 and resistors 75 for the third transmitter pulses. Resistor 77 controls the width of the unblanking pulses applied to the fine scale display tubes and a wider unblanking pulse is applied over line 81 to the coarse scale tube .15. The circuit of a suitable blanking device 65 is described with reference to Fig. 2 (not shown).
