Abstract: 858,294. Nuclear fuel elements. GENERAL ELECTRIC CO. Ltd. July 16, 1958 [July 16, 1957], No. 22576/57. Class 39(4). [Also in Group XXII] A protective can for a nuclear reactor fuel element is made by forming a tubular body portion with a plurality of integral fins along its length, slotting the fins axially and deforming the tip portions of the fin segments so formed. The can body 1 and two groups of fins 2 for heat transfer and 3 for stiffening are made of magnesium alloy extruded through a straight die, and the fins 2 are then slotted and twisted to a helical shape. The can is completed by closure of the ends after insertion of the fuel element. In a modification the body is extruded with helical fins 5, 6 or is twisted as a whole after extrusion. The fins 5 are slotted and then twisted so that their outer edges are parallel to the longitudinal axis of the body as shown in Fig. 8 (not shown). If the thickness or the nature of the material of the fins is such that they are difficult to twist they may instead be slotted at an angle normal to the surface of the fin. Specifications 791,011 and 828,351 are referred to.

Abstract: 888,223. Conveyers. HAMMOND MACHINERY BUILDERS Inc. July 2, 1959 [July 17, 1958], No. 22821/59. Class 78 (1). [Also in Group XXIII] Articles are fed beneath an abrasive belt 6 by an endless conveyer band 12 of perforated construction on which the articles are held by a current of air passed downwardly through the band, the area of the perforations being substantially larger than the area occupied by the articles and so large in relation to the total area of the band that the articles are held on the band by the air flowing past the edges of the articles. The current of air is produced by a fan incorporated in a dust collector 21 connected to a chamber 16 below the belt, the collector 21 having a cyclone 23 to collect abrasive dust. The band comprises either a wire mesh belt or, as shown, a series of slats each having staggered rows of slots 14 which align with slots 25 in a plate 20 covering the chamber 16.

Title: Improvements in or relating to a triple valve for air brakes, more particularly for railway vehicles
IPC: B60T15/18
Filed: 1954-08-05
Abstract: 751,070. Fluid-pressure brakes. KNORRBREMSE GES. Aug. 5, 1954 [Aug. 5, 1953], No. 22824/54. Class 103 (1). In order that the triple valve for air brakes, more particularly for railway vehicles, may be returned to the inoperative brake release position as soon as possible after the pressure in the main air pressure line has been returned to normal to enable a rapid re-application of the brakes to be effected if desired, control means having a sensitivity aperture are provided between the constant pressure control chamber and the main air supply line so that when the constant pressure control chamber and the main air supply line are in communication, a piston system of the triple valve has yet to reach a fully released position and wherein the control means are adapted to reduce the cross-section of the sensitivity aperture to the normal size at the latest movement when the piston system of the triple valve reaches the fully released position. In the released state of the brake illustrated in Fig. 1, in which an accelerator incorporated in the circuit is not shown, the main air line 15 supplies pressure to the auxiliary reservoir 39 and to the triple valve chamber 7 of the triple valve 1 via pipe lines 11 and 9 and to the constant pressure control chamber 5 via open valve 55 of a control device 47 and pipe line 63. The brake cylinder 29 is un-pressurized, being open to atmosphere via-pipe line 31, open tubular member 17 and aperture 35 of the triple valve 1 and is cut off from the auxiliary reservoir 39 by closed valve 25. The triple valve operates in the normal manner when the operator initiates a brake application by reducing the pressure in the main air line 15; the increased pressure in the brake cylinder 29 forcing piston 49 of the control device 47 to the left to close valve 55 and open the sensitivity port 62 fully by moving the sensitivity port throttling member 59 to the dotted position illustrated. On release of the brakes, when the operation has progressed so far that the triple valve piston system has not yet reached its end position and the residual pressure still effective in the brake cylinder 29 can no longer keep the valve 55 closed, the latter is opened by the force of spring 53. The large flow cross-section between chambers 45 and 61 of the control device 47 is open for a short time, upon the valve 55 rising from its seat 57, before being decreased by the throttling member 59. This short time during which there exists a substantial unrestricted communication between the control chamber 5 and the chamber 7 of the triple valve and the main air line 15 enables the pressures in chambers 5 and 7 to be equalized to permit the triple valve to reach its bottom end position to enable a rapid re-application of the brakes to be carried out if desired. An alternative arrangement is described in the Specification wherein a modified form of triple valve works in conjunction with an accelerator and a modified form of control device to achieve the same object.

[Also in Division F1] Exhaust gases from a gas turbine engine 12 (Fig. 1, not shown) are guided through a conduit 16, Fig. 2, enveloped by a casing 24, to turbine blades 18 situated at the radially outer extremities of blades 20 of a lift fan (22). Casing 24 forms with conduit 16 induction nozzles 28, 30, and air passing through inlet 34 forms a low pressure area adjacent nozzle 28, so that ambient air at atmospheric pressure is induced to flow through apertures 17 in the casing 24 and along the annular space 26 defined thereby to fill the low pressure area, where it is entrained in the airflow through inlet 34, thus providing a constant cooling flow around the conduit 16. Also, the hot gases passing out of fan turbine duct 32 create a low pressure area adjacent nozzle 30, and some of the ambient air is induced to flow through nozzle 30. The sizes of apertures 17 may be varied relative to each other, and baffle-shaped members may be placed in the annular space 26 as an air flow control.

Title: Apparatus for the preliminary separation of crude benzols
IPC: C07C7/04
Filed: 1928-08-13
Abstract: 295,591. Soc., des Etablissements Barbet. Aug. 12, 1927, [Convention date]. Mineral oils and tars, distilling. - Crude benzol is roughly separated into four products : benzol, toluol, xylol and solvent naphtha, the first three by continuous rectification under atmospheric pressure and the last by a discontinuous rectification under a vacuum. Crude benzol, from which water has been removed by decanting is pumped into a reservoir A, whence it is delivered hourly by a coil 2 through a pipe 1 to a heater E thence to the exhausting plates of a column B<11>, heated from a coil C, the less volatile elements from the column B<11> condensing in the heater E, so that vapours issuing by a pipe 5, 6 to a column B from the upper plates B<1> of the column B<11> contain only a small proportion of the heavy products xylol and solvent naphtha. The column B is surmounted by a cooling condenser G, from the top of the outlet of which impure products such as sulphide of carbon pass out through a test safe H. At the point 8 90-95 per cent benzol is led to a cooler M and a test safe J. The residual liquid consisting of toluol passes through the heater D of the column R through a cooler M to a test safe K. Xylol is separated from the crude benzol issuing from the column B<11> through the heater C between the plate O, O<1> of a second column, the xylol being extracted at 16 while a small fraction descends from a condenser G<1> which provides the reflux to a test safe L. Heavy products are drawn off at 17 and, with the xylol, are cooled in a cooler T and pass out through test safes N, Q. The crude heavy products drawn off at 18, pass through crystallizers R in which naphthalene is extracted, the decanted liquids being put into a reservoir S. This liquid is rectified discontinuously under vacuum, in a boiler U heated by a coil u, and provided with rectifying plates V and a cooling coil X. A part of the distillate is led from the exit back to the column V while the main portion, the solvent naphtha, passes to a flask Y. The residue in the boiler U is a tar. In a modification, the column O O<1> is omitted, the liquid passing directly from the heater C to the crystallizers R. In this modification, if desired, more plates V may be provided and the distillate collected in two fractions, thus roughly separating the xylol and solvent naphtha. In a further modification the discoutinuous apparatus U, V is replaced by a continuous apparatus similar to the column O, O<1>, but working under a vacuum.
