Abstract: 960,349. Heat exchanger tubes. COMMISSARIAT A L'ENERGIE ATOMIQUE. Jan. 21, 1963 [Jan. 26, 1962], No. 2534/63. Heading F4S. [Also in Division G6.] A tubular heat exchange element includes fins which are plane and of constant height either over their whole length or with the exception of short portions at their ends set perpendicularly or at an oblique angle on the external wall thereof and arranged parallel to each other in an even number of identical sectors around the element, the fins being inclined in opposite directions in adjacent sectors to form a herring-bone series. In Fig. 1, a tubular element 1, the central portion 2 of which is reserved for the flow of the primary heat exchange fluid, includes six identical sectors 3a, 3b, 3c ... &c., each sector being delimited by two generator lines 4 parallel with the element axis, and comprising a series of plane and parallel fins 5 on a plane surface. Alternatively, the fins may be disposed on concave sector surfaces. The fins in adjacent sectors are alternately inclined to form a herring-bone pattern, whilst the angle of inclination to the element axis may be within the limits of 10 degrees to 70 degrees, with an optimum between 15 degrees and 45 degrees. The fins may be rectangular or trapezoidal, and may be machined at their extremities to form recessed portions 7 of substantially triangular or dovetailed shapes. Their extremities may also be deflected slightly causing a changed angle of inclination. The inclined fins induce vortical movements of the secondary fluid which flows through the container housing the element. The number of sectors of the element can be varied. Lateral extensions with hollowed out portions may be formed in one piece with the element on alternate generator lines to effect the centering of the element in its container.

Title: Method of and apparatus for the production of filter rods
IPC: A24D3/02
Filed: 1953-01-29
Abstract: 729,678. Filter paper. PAPIERFABRIK FLEISCHER GES. Jan. 29, 1953 [Aug. 6, 1952], No. 2600/53. Class 96. [Also in Group VI] Filter rods such as used for tobacco smoke filters are formed by continuously cutting material in sheet form, for example tissue paper, into narrow longitudinal strips and passing it through two successive pairs of rollers, the first pair of which may effect the cutting, the rates of rotation of the said pairs of rollers being such that the rate of travel of the material through the second pair of rollers is less than that through the first pair to cause the narrow strips to buckle up and form a fleece which, in the same operational sequence, is formed into rod shape. Two sheets of paper from webs 1, 3 are formed into a doublelayer sheet 8 which is cut into narrow strips by rotary disc cutters 11, 12 and a third sheet 9 from a web 5 is cut by cutters 15, 16. The cut sheets from the two pairs of cutters pass through pairs of rollers 19, 20 and 21, 22 which run more slowly than the cutters and cause the narrow paper strips to curl up and form continuous fleeces 23, 25 of paper wool, which fleeces combine at 26 to form a single fleece which is passed through a trough 27 and shaped into a continuous rod 32 by rollers 30, 31. The rod passes through further shaping rollers 35, 36 to a wrapping mechanism in which it is wrapped in paper, the wrapped rod being later cut into filter tips suitable for cigarettes. The cutting rollers 11, 12, 15, 16 each comprises a number of parallel rotary cutting discs, the discs of one cutter e.g. 11 being situated between the discs of its associated cutter 12, and stripping devices 13, 14, 17, 18 are associated with each pair of cutters to prevent paper being carried around with the cutters. Either the fleece or the completed filter rod may be sprayed with chemicals which have the effect of absorbing the substances which it is desired to remove from tobacco smoke. Alternatively the sheet material or the fleece can be dyed, charged with perfume, or flavoured.

Abstract: 844,528. Re-ignition devices for continuous combustion internal combustion engines. BRISTOL SIDDELEY ENGINES Ltd. Jan. 22, 1958 [Jan. 30, 1957], No. 3332/57. Class 75(3). [Also in Group XXVI] A re-ignition device for a continuous combustion internal combustion engine comprises a carrier member adapted for attachment to the wall of the combustion chamber and a re-ignition member having a part of refractory material which in its inoperative position is wholly or partly withdrawn from the combustion chamber. In the form shown, the device comprises a carrier in two parts 1, 2, the part 1 being secured to the wall 8 of the combustion chamber. The re-ignition member comprises an openended tube 16 slidable in a bore in the part 1 by means of a hollow root part 17 enlarged at 18 to form a piston fitting the bore, the inner end of the tube being closed by a plug 60. The part 17 is further enlarged at the rear end to form a second piston 20 moving in a bore 21 in the part 2. Air is bled from the engine under control of a valve through a port 24 in the part 1 and a pipe 25 to the space above the piston 20. The tube 16 can be retracted from the combustion chamber by gas pressure or moved into operative position by compressed air acting on the piston 20. The control valve for this purpose is operated by a solenoid by means of a switch. Where it is desired that the ignition should not take place if the speed of rotation of the engine is below a certain value, the switch may be arranged in series with the second switch controlled by, for example, centrifugal pressure in the piston block chamber of the engine fuel pump. Specification 819,141 is referred to.
