Abstract: 990,648. Capacitors. C.C.L. Ltd. March 28, 1963 [March 28, 1962], No. 11927/62. Heading H1M. In a spirally wound type of capacitor an insulating spacer is inserted between the capacitor unit and the terminal deck in the space defined by the leads so that when the capacitor leads are deformed during assembly they are prevented from contacting one another. In one example five foils such as 2, Fig. 1, with interleaved paper strips 3 and 4 are wound round a spindle which is then withdrawn to leave an axial bore 10. Four of the foils are of aluminium oxidized on the surface whilst the fifth (negative electrode) is of unoxidized aluminium, and each foil is provided with a connecting strip, such as 6-9. After winding the unit is impregnated with electrolyte and the connecting strips are riveted at 12-16 to an insulating disc 17 forming the terminal deck. The insulating spacer 19 is provided with a boss adapted to engage the axial bore 10, and after it has been inserted the effective length of each lead is reduced by rolling it. An insulating tape 21 is wound outside the deformed leads to insulate them from the tubular metal casing into which the unit is inserted. The spacer element may be provided with radial projections adapted to project between adjacent leads, and the tape 21 may be replaced by a split collar or by a continuous band of resilient material.

Title: An improved fuel supply system for a liquid fuel burner
IPC: F23D11/28
Filed: 1952-01-07
Abstract: 744,782. Supplying fuel to liquid-fuel burners. ORR & SEMBOWER, Inc. Jan. 7, 1952 [Feb. 28, 1951], No. 12274/53. Divided out of 744,747. Class 75(1). A fuel recirculating fitting for use in a liquid fuel burner system contains valves which normally close a fuel conduit supplying a burner nozzle and directs fuel to a return connection and a pressure responsive device is built into said fitting and is adapted to shift the valves to open the fuel conduit to the burner and prevent circulation of fuel through the return connection. The recirculating valve illustrated comprises two valves 130, 132 adapted to seat, respectively, against opposite ends of a passage 128, the valve 132 being held seated by a spring 144 when the burner is inoperative, so that preheated fuel passes from the supply line through inlet 29, passage 128, chamber 124, and outlet 33 to the fuel return line. When the fuel in the fitting is sufficiently heated it is supplied to the burner by introducing compressed air through an inlet 158 to operate a piston 154 to move the valve assembly to seat and unseat the valves 130, 132, respectively. Fuel is then prevented from passing to the return line and is directed past the member 132 into a conduit 31 leading to the burner nozzle (not shown). The fuel in the conduit 31 is heated by the passage through a surrounding tube 151 of steam or heated compressed air for atomizing the fuel at the burner nozzle. An alternative construction is described in which the two valve members are rigidly connected together. Specification 744,747 is referred to.

Title: A process for the halo-substitution of unsaturated organic compounds
IPC: C07C17/156
Filed: 1940-07-31
Abstract: 542,086. Halogenated hydrocarbons. SHELL DEVELOPMENT CO. July 31, 1940, No. 12415. Convention date, Sept. 5, 1939. [Class 2 (iii)] The halogenation by substitution of unsaturated compounds is effected in the presence of small quantities of oxygen not exceeding 5 per cent. by volume at a temperature above that at which halogenation by addition is favoured but below that at which substitution occurs in the absence of a catalyst. Many initial compounds are mentioned, including olefines, cyclo-olefines and chlorinated and brominated olefines and cyclo-olefines. The temperatures required are usually above 250‹ C. Examples describe the chlorination of ethylene and propylene, with or without a diluent gas such as nitrogen. Preferably the olefine is employed in excess, for instance in volume ratios of 2 : 1 to 7 : 1 or more. Instead of using free chlorine or bromine, a substance yielding them may be used. The re-actants or one of them should be pre-heated separately as halogenation by addition occurs at low temperatures. The oxygen may be added before or after mixing the re-actants. The reaction chamber may be made of or lined with resistant material such as hard carbon.

Title: Rotary sealing mechanism
IPC: F04D29/14
Filed: 1961-04-06
Abstract: 938,820. Stuffing-box substitutes. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. April 6, 1961 [April 7, 1960], No. 12449/61. Class 122 (5). A sealing arrangement for the rotary shaft 34 of a compressor or other machine comprises means to supply sealing gas at subatmospheric pressure to a space 49 intermediate inner and outer spaces 42 and 48 respectively and suction means, for example vacuum pumps 58 and 56, connected to the spaces 42 and 48 to maintain pressures in each of those spaces less than that in the space 49. A compressor wheel 31 secured to the shaft 34 has a sleeve 35 coaxial with the shaft and mounted on bearings 36 in the machine casing 33. Helical grooves 38 and 38a of opposite hand in the sleeve 35 extending from a land 39 oppose leakage along the sleeve of compressor gas, which may be uranium hexafluoride, from space 62 and of sealing gas from space 42. The sealing gas, which may be nitrogen, is supplied to the space 49 through duct 52. Compressed air is supplied through a duct 50 to a space 47 and bearings 36 are lubricated by a mixture of oil and air fed from a mixer 57 through a duct 54. The spaces 47, 48, 49 and 42 are separated by serrated sections L1, L2 and L3. In operation, nitrogen supplied to the space 49 flows partly to space 42 where it is drawn off by pump 58 and partly to space 48 where it is drawn off by pump 56 together with compressed air flowing from space 47 through section L1. The remainder of the compressed air in space 47 escapes outwardly past the bearings 36. When the compressor is at rest or rotating at a speed below a certain value a sealing member 41 operated through rods 44 is automatically moved to sealingly engage seats on the sleeve 35 and the casing 33. Specification 820,348 is referred to.
Patent GB-584973-A (GB)
Title: Improvements in or relating to delivery mechanism for newspapers and like articles
IPC: B65H29/66
Filed: 1944-07-01
Abstract: 584,973. Delivery apparatus for printing machines. IGRANIC ELECTRIC CO., Ltd., and RAPLEY, H. H. July 1, 1944, Nos. 12564 and 16013. [Class 100 (i)] [Also in Group XXX] In a delivery mechanism for newspaper and other articles which have to be delivered by a shoot on to a conveyer in overlapping relation, means are provided to ensure that each article entering the shoot overlaps the preceding one on the correct side. The papers pass from the folding cylinder between folding-off rollers 1, Fig. 1, into a shoot 5, 6a, 6b which directs them on to a belt 2. From this belt they pass on to a fly belt 3, and are spaced thereon by a rotary device 4 provided with teeth 4a. The disposition of the parts is such that each copy is forced downwards by the rollers 1 until its lower end is on the belt 2 and is nearly in engagement with the teeth 4a. When the copy leaves the rollers 1, its upper part is blown against the set-back portion 6a of the shoot by a current of air from a number of nozzles 7, thus leaving a space for the next copy to overlap it. The jets of air may be replaced by a pusher which is reciprocated by an eccentric. The parts 5, 6a of the shoot are fixed, but the part 6b is pivoted at 24 to a member 20 which is adjustable along a structure 19. This structure is pivoted on a fixed axis 21 and also is pivoted at 22 to the upper end of a strut 23. The structure carries pulleys for supporting the belts 2, 3, the latter of which is in two sections. If jamming occurs in the shoot, the part 6b is forced towards the left, and this movement, through an arm 36 and Bowden wire mechanism 37, releases the strut 23, which moves downwards with the structure 19 to relieve the congestion. Downward movement of the strut is prevented normally by the engagement of a pawl 32, Fig. 3, with a ratchet wheel 31 on a shaft 30. This ratchet is geared to a pinion 26 which meshes with teeth 25 on the lower end of the strut. The pawl 32 is released by the action of a cam block attached to the cable 37 on a ball 40 which is mounted in an arm 41. As the strut moves downwards a projection 43 thereon engages the arm 44 of a switch control element and cuts off the current from the press motor. This control is locked in the " off " position by the engagement of a latch 47 with the arm 46. This latch can be withdrawn only by the operation of a pass key. The strut can be raised by turning a handwheel 48, Fig. 1, which is rigid with the ratchet. Specifications 560,366 and 584,998 are referred to.
