Abstract: 1358073 Minimising fires in fuel tanks C CHITI 9 June 1971 [6 Aug 1970 17 Feb 1971] 19623/71 Heading A5A [Also in Division B7] A fuel tank for a vehicle to reduce fire risk on collision comprises first and second sets of chambers, the chambers of each set communicating with one another but being sealed from the chambers of the other set. One set of chambers is provided with means enabling it to be filled with fuel and the other set is provided with means enabling it to be filled with a fluid which, when mixed with the fuel, makes the fuel non-flammable. In one embodiment (Fig. 1) an outer vessel 11 contains a stack of corrugated sheets with the corrugations running alternately cross-wise and separated by sheets 13. The spaces 14 thus formed contain, in use, fuel and the spaces 15 contain the other fluid e.g. a halogen. Duct 18 communicates with fuel spaces 14 and the duct 20 communicates with the other spaces 15, both ducts having pumps 19, 21 to remove the respective contents in a constant ratio. Tubes 23 and 22 are for venting, while 16 and 17 are inlets for fuel and for the other fluid respectively. In a modification the fuel and fluid chambers are formed by a spaced array of generally square-section ducts each containing a concentrically placed pipe. (Fig. 3, not shown). The tank may comprise an array of pairs of preformed sheets which together define two sets of spaces, connected together respectively, for containing fuel and the other fluid.

Abstract: 735,493. Snap-action spring mechanisms. ROBERTSHAW-FULTON CONTROLS CO. July 17, 1953, No. 19908/53. Class 108 (3). [Also in Group XXXVII] A snap-action device comprises a dished circular disc A having a pair of parallel slots 10, 10 positioned one on either side of the centre of the disc, and a transverse slot 14 connecting the slots 10, 10. The slots 10, 10 and 14 define a pair of oppositely disposed spring arms 16, 16 which extend in planes tangential to the surface of the disc A. The angle between the slot 14 and the slots 10, 10 is preferably between 30-45 degrees. The disc A is formed from dies of uniform spherical radius, but the slots 10, 10 and the slot 14, tend to produce distortion in the disc. This results in the formation of opposed sectors (shown shaded) in which given points (e.g. X, X) are of greater disc height than points of equal radii (e.g. Y, Y) in the remaining (unshaded) sectors. As applied to a valve mechanism, one side of the disc A is contacted by a peripherally-disposed knife edge 20 of a thrust element 18. The other side of the disc A engages a ring 26. A valve stem 28 seats on the arms 16. The device may also be used for operating switches.

Abstract: 275,240. Soc. P. Genestin et Cie. July 30, 1926, [Convention date]. No Patent granted (Sealing fee not paid). Blocks and shoes acting on drums; force-transmitting mechanism.-In operating mechanism for the brakes of steering wheels of motor vehicles a head on the operating lever which is pivoted upon the steering pivot is given a longitudinal movement along the pivot axis by means of helical surfaces and engages a brake shoe separating lever between the pivot and the operative end of this lever. The fixed steering pivot 4 is provided with a collar 5 on which is formed a helical surface engaged by a correspondng surface on a head 7 having an operating arm 6. The head 7 is provided with a rod 3 slidable in the pivot 4 and engages an adjusting screw on a lever 8 pivoted at 11 on an anchor plate 12 secured to the stub axle 2. A pair of brake shoes pivoted at 14 to the plate 12 carry at their free ends rollers between which engages a wedge-shaped head 10 on the lever 8. When the head 7 is turned by the arm 6 to apply the brake it moves along the pivot 4 and operates the lever 8 the bead 10 of which applies the shoes to the drum 17. The Specification as open to inspection under Sect. 91 (3) (a) states that a screw thread or other device may be employed instead of the helical surfaces for operating the head 7.

Abstract: 1283961 Impact pulverisers BARDON HILL QUARRIES (LONDON) Ltd 14 July 1970 [19 April 1969] 20094/69 Heading B2A An impact pulverizer, particularly for comminuting minerals or nut shells, comprises a rotor 14, Fig. 1, and a stator casing 10. Fig. 2, including fragmentation chambers F. Each chamber F includes a sweeper wall 26 mounted in the rotor, and is bounded by inclined side walls 16 curved impact members 15, top wall segments 18, releasable covers 18 and a releasable bottom 12. The rotor compirses upper and lower discs 22, 23 bolted at 24 Fig. 3 and circumferentially-spaced impeller blades 25. The sweeper walls 26 are secured between the discs 22, 23 by bolts 27, Fig. 1, and may be resiliently mounted, e.g. on rubber. The casing has a central opening closed by a cover 28. The parts 16, 18, 26 may have ribbed or toothed surfaces. In operation, material enters the rotor from a box 29 via openings 30, is hurled by the blades 25 against the walls 15 and falls out via openings 31. The size of the product is determined by the speed of rotation of the rotor. Fan blades 32 draw in air via slots 33 and thus balance the internal pressures and prevent passage of excess dust across the parts. Entry of tramp metal causing an undesired out-of-balance effect may be used to operate an inertia switch stopping the apparatus and/or giving an alarm signal. The frame of the machine may be protected by hardened-steel toothed or ribbed elements. The working faces of the apparatus which are subject to extreme wear may be protected by tungsten carbide inserts dovetailed to the main components.

Title: Process and apparatus for fractional distillation of mixtures of substances
IPC: B01D1/00
Filed: 1934-07-09
Abstract: In a stillhead for fractional distillation comprising a number of superposed planes connected in series or in parallel and completely filling the horizontal cross-section of the column, the liquid is in the form of a thin film beneath a vapour stream of low <PICT:0444014/III/1> <PICT:0444014/III/2> <PICT:0444014/III/3> height and relative movement between liquid and vapour takes place.  The path of the channels may take the form of intermittently ascending planes connected by short vertical or inclined steps, substantially horizontal planes only, or slightly continuously ascending planes. Eight units each constructed in this manner are laterally assembled in a column above a kettle 5, the sides of which incorporate steam, hot water, gas or electric heaters 8.  Receivers 6 for each unit may be arranged for collecting the fractions and in this distillation of substances of high boiling point the cover 11 may be heated.  The channels may be formed between plates arranged as a continually ascending helix, as shown in Fig. 7, the liquid reflux descending beneath the ascending film of vapour.  The stillhead may be shut off from the kettle by a tight checkvalve, the liquid in the stillhead being then fractionated under pressure or vacuum.  In a modification, Fig. 4, in which the channels take the form of horizontal planes or continuously ascending planes, the planes have a common inlet and outlet, the latter leading to an adjoining air, oil, water or brine cooler 28.  The planes may be roughened, corrugated or covered with a thin layer of a fibrous material such as cotton, silk, glass or asbestos or slag wool or coated with a layer of colloidal material such as absorption carbon or silica gel.  The reflux is enhanced by allowing such covering material to overhang from one plate to a lower one.  In examples, light oil is fractionated to give carbon disulphide, benzol, toluol and xylol and crude anthracene to give dimethyl naphthalene, acenaphthene, fluorene, pure anthracene, phenanthrene, carbazol and fluoranthene.  In each example, the stillhead is shut off from the kettle when filled with a suitable mixture of fractions, and the latter then separated by decreasing the pressure.  The stillhead is kept at suitable temperature such as by a hot inert gas.

The loop in the wire is formed between pulleys 15a, 15b by a pulley 15 driven downwardly by a pneumatic cylinder (14), Fig. 4 (not shown). Hooks 8 of gripping means 7, 7a are then raised by pneumatic cylinders 10 to hold the wire 6 and cranks 11 are rotated to wind it around the lugs. As the hooks 8 are withdrawn after winding, the wire 6 is broken. The supports are rotated by a motor in engagement with gears 16, 17, to dip the wound lugs into a tin bath (18) after immersion in activating agent, e.g. colophony, Figs, 5a, 5b (not shown). The lugs may then be bent by a punch (20), Fig. 6 (not shown), to slacken the coil ends, which may have tightened during soldering. In alternative embodiments, a single gripping means may be used to wind the wire around the lugs and the spools may have more than two lugs where the coils are formed of more than one winding or have intermediate taps.
