Abstract: 1,200,934. High pressure apparatus. N. KAWAI. 11 Aug., 1967 [13 Aug., 1966; 14 March, 1967 (5)], No. 37038/67. Heading B1X. [Also in Divisions H1; C1] High pressure apparatus comprises a first stage multiple piston assembly 11 in the form of a solid body of regular geometrical shape subdivided by planes passing through its centre, the inner end of each piston 12 so formed being truncated so that a pressurisable space 15 5 is formed at the centre of the piston assembly; at least one further stage multiple piston assembly 17 enclosing the first stage assembly and similarly formed by subdividing a solid body of regular geometrical shape to form pistons, these being truncated at their inner ends to define a space conforming in shape to the outer surface of the first stage assembly; the gaps between neighbouring pistons of each assembly being at least partly covered by the pistons of the immediatly surrounding piston assembly and spacer elements 19 between adjacent faces of the pistons in each stage and between adjacent stages. The assembly may be enclosed in rubber or synthetic resin covers 21 through which pass leads for electrically heating the sample., Pressure may be applied by immersing the assembly in pressurised fluid (Fig. 12 not shown), or by detonating explosive in an annular space between concentric layers of rubber surrounding the outermost piston asembly (Fig. 13 not shown). In the embodiment of Fig. 14, the first stage piston assembly derives from a sphere, the second from a pair of truncated terahedrons mounted base to base and the third form a pair of truncated cones similarly mounted, and presure is applied mechanically through rams 49 and 50. Adjacent pairs of pistons may have interfitting projections and recesses respectively in opposing faces (Fig. 7 not shown or at least one of each pair of opposing faces may have a concave recess (Fig. 4 not shown). There are references to use of the apparatus in obtaining polycrystalline aggregates of diamond, Group 2-6 compounds such as ZnO, ZnTe, Group 3-5 compounds such as Ga Ar, BN.

Title: Improvements in or relating to liquid spray systems for use in conjunction with coalcutting and winning apparatus
Inventor: BEST GEORGE JACKSON
IPC: E21C35/22
Filed: 1960-10-28
Abstract: 965,233. Mines &c. GUILLICK Ltd. Sept. 12, 1961 [Oct. 28, 1960], No. 37041/60. Heading E1F. A spray system for a coal cutter comprises a series of spaced sprays 16 and means 18 for turning the sprays on and off in sequence so that only the spray or sprays adjacent the cutting member 10 of the cutter is or are operative as the member moves along the coal face. As the plough 10 moves it is supported by hydraulic rams 11 fastened to a conveyer 12 and connected to feed and return pipes 13, 14. Each spray is connected to a supply pipe 17 by pipes 21, 23 and the means 18 which is also connected to the pressure side of a ram by a pipe 13b. As the plough passes a ram the back pressure on the ram causes a build-up of pressure in the pipe 13b depending on the setting of a restrictor 32 in the means. The increased pressure moves a plunger 27 to open a valve 24 in the means to permit liquid from the pipe 17 to pass to the spray. In modifications an arm on the plough operates the valves controlling the sprays, and a timing mechanism operated by the plough drive means controls the sprays.

Title: Phosphonium salts and a process for the preparation thereof
IPC: C07D303/40
Filed: 1972-08-09
Abstract: 1391806 Quaternary phosphonium salts. ROCHE PRODUCTS Ltd and BCL WEEDON 9 Aug 1973 [9 Aug 1972] 37165/72 Headings C2P and C2C [Also in Division C3] The invention comprises phosphonium salts of the general formula wherein R<SP>1</SP>, R<SP>2</SP> and R<SP>3</SP> are each an aryl group, especially phenyl, and X- is a halogen anion, e.g. Br or Cl. They may be obtained by reacting a triol of the formula with an appropriate triaryl phosphonium halide. Both the cis and trans forms of the triol can be used in the process. The reaction is suitably effected in an inert organic solvent, e.g. methanol. The phosphonium salt products can be reacted with polyene aldehydes to give a wide range of carotenoid compounds. Suitable aldehydes include the aldehyde of the formula which reacts to give azaprin methyl ester of the formula The latter reaction can be carried out by heating in a closed vessel in the presence of butylene oxide or in the presence of isopropanol, KOH and water, at - 30‹ to - 10‹ C. Other aldehydes which may be used include which by heating with a phosphonium salt (I) in the presence of butylene oxide yields When 2 moles of phosphonium salt are reacted with (XV) in the presence of isopropanol, KOH and water, the product is a carotenoid compound of the formula The carotenoid compound 5,6-dihydroxy-5,6- dihydro-#-carotene may also be prepared by using the phosphonium salts (I). The triol starting materials of Formula (II) may be obtained by three different routes A, B and C. In route A, 6-hydroxy-2,2,6- trimethylcyclohexanone is converted to the corresponding 6-trimethylsilyl ether which is then reacted with 3-methyl-2-cis-en-4-yn-l-ol to yield which is then reduced with an alkali metal aluminium hydride to form a cis-trio (II). In route B, #-ionone is first converted to its epoxide which is then reacted with carbomethoxymethyl triphenyl phosphoran or with diethyl carboethoxymethyl phosphonate to form a mixture of cis and trans epoxy esters, viz the mixture of esters is separated, each ester is independently hydrated to form the corresponding 1,2 dihydroxy . compound and the latter reduced with an alkali metal aluminium hydride to form the corresponding cis and trans trihydroxy compounds of Formula II. In the third route (C) #-ionone is first converted to #-ionylidene acetic acid which is then epoxidized to form the epoxide of formula the latter is then treated with acid to form the 1<SP>1</SP>;2<SP>1</SP>-dihydroxy compound which is then esterified to convert the -COOH group to -COOCH 3  and the resulting ester then reduced as above to form a 2-trans triol of Formula II.

Title: Motor vehicle transm9ssion
IPC: F16H47/08
Filed: 1972-08-10
Abstract: 1347185 Change-speed gearing; friction clutches GENERAL MOTORS CORP 10 Aug 1972 [16 Aug 1971] 37295/72 Headings F2D and F2C In a transmission for a motor vehicle having an engine-driven input shaft 10 drivingly connected to a torque converter 14 and a fluid pump 36, mechanical self-engaging mechanisms 80, 82 on the input clutches 18, 20 provide a back-up drive from the output shaft 12 to the torque converter 14 during engine-off coast drive conditions in all of the transmission drives including neutral to maintain the pump 36 operable. As shown, clutches 18, 20 are normally engaged by means of pressure fluid in the cylinders 94a, 94 to couple the input shaft 38 with the ring 50 and the suns 56, 58, respectively, of the planetary gearing 16. When the cylinders 94, 94a are not pressurized, springs 100, 100a act to disengage the clutches. The pistons 88, 88a of the clutches 18, 20 are formed with ramps 86, 86a, Fig. 3 (not shown), and balls 90, 90a are engaged between the ramps and floating discs 92, 91a which normally rotate with the pistons. When the pistons are driven by the output shaft, when the vehicle is coasting with the engine stalled or when being push-started the balls cause the discs 96, 96a and 98, 98a to be engaged thereby engaging the clutches 18, 20. If the transmission selector is in neutral and the vehicle moves in a forward direction, the suns 56, 58 and the ring 50 will be driven in a forward direction, causing the mechanisms 80, 82 to engage the clutches 18, 20 and thereby driving the pump 36 through a one-way device 34. The pump 36 will be driven similarly if the vehicle moves in reverse or if the vehicle coasts in a direction corresponding to that for which the transmission control is conditioned. The pump 36 supplies additionally the power steering system and the power brake system.

Title: Improvements in and relating to the production of plastics articles having printed deigns on the surface thereof
IPC: B44C1/17
Filed: 1963-09-23
Abstract: 1,107,401. Printing processes. R. E. CHAPMAN. 17 Sept., 1964 [23 Sept., 1963], No. 37323/63. Heading B6C. Printed matter is reproduced on the surface of an article made of a homo- or co-polymer of vinyl chloride by transfer from a temporary support member. Preferably, the vinyl chloride is sprayed with a plasticizer, e.g., diiso-octylphthalate, before applying the transfer. The latter may be paper printed with pigments such as carbon based pigments including Carbon Black, a mixture of Benzedene and Chrome Yellows, Phthalocyamine (Blue), a mixture of Carbon Black and Bronze Blue and Calcium Toner (Red). In a preferred embodiment of the invention the printed surface of the support member is contacted with the surface of an article composed of transparent plasticized vinyl polymer and after removing the support member a coating of a pigmented plasticized vinyl polymer is supplied to the printed surface of the transparent article and is then fully gelled e.g. through immersion in a glycerol bath. By selecting the appropriate pigments the background of the design reproduced can be varied over a wide range of colours to produce, for example, abrasion and corrosion resistant labels, particularly ring labels, bearing a title or name. The support member could be contacted with a pigmented plasticized vinyl polymer or copolymer and a transparent coating of plasticized vinyl polymers or copolymers applied thereto, but in that case the design on the support member is in mirror image of that required on the finished product. In the manufacture of a moulded plastic article such as a cloth preprinted transparent thin sections resulting from the application of the method of the present invention may be incorporated in the mould before introducing a curable resinous composition (or plastisol or rigisol in the case of plasticized resin dispersions) so that after curing of the resin (or gellation of plastisol) the transparent sections are bonded to the cured resin (or gelled plastisol). In this way all necessary legends or colours (e.g. lips or eyes on a doll) can be embodied in a shaped article in one operation and, further, be protected from abrasion by a transparent layer.

Title: Improvements relating to fluid control valves
IPC: F15B21/10
Filed: 1963-09-23
Abstract: 995,979. Fluid-pressure apparatus. R. R. GORDON. Sept. 23, 1963, No. 37335/63. Heading F1P. Rapid advance of an hydraulic or pneumatic operated piston 4 Fig. 1 towards a machine tool followed by slow controlled advance is effected by allowing exhaust from cylinder space 7 to pass along a conduit 14<SP>1</SP> to the upper side of a control valve piston 21 Fig. 2 the underside of which exhausts through a conduit 14<SP>11</SP> leading to a conduit 12 and to a combined inlet and outlet distributing valve which in the position shown supplies pressure fluid through a conduit 11 to the cylinder space 6, the piston 21 on reaching the end of its stroke closes conduit 14<SP>11</SP> and opens a check valve 16 in a conduit 13 in parallel with conduit 14 and including a metering valve 18 through which fluid is exhausted from cylinder space 7 is exhausted during the slow speed portion of the stroke of piston 4. During the rapid advance period fluid gains access to cylinder space 28 through a groove 50 in the cylinder wall 22, an annular space 49 between said wall and an outer casing 23, and cylinder ports 48. Opening of check valve 16 is effected by a hollow pin 41 carried by piston 21 and having lateral ports 61, through which at the start of the return stroke of piston 21 and hence of piston 4, pressure fluid passes to unseat a ball 62 and traverse ports 53 to gain access to substantially the full underside area of piston 21 thereby effecting rapid return thereof. A second check valve 17 in conduit 13 remains closed. On reaching the end of the return stroke which may be varied by an adjustable stop 46 a ball 35 is unseated thus allowing access of pressure fluid from valve 10 to the cylinder space 7 to complete the return stroke of piston 4.

Title: Improvements in or relating to bobbin changing mechanisms
IPC: B65H54/553
Filed: 1968-08-06
Abstract: 1,240,492. Bobbin changing mechanism. HEBERLEIN & CO. A.G. 6 Aug., 1968 [11 Aug., 1967], No. 37492/68. Heading D1J. A pair of spaced apart frames 11, 12 carry between them a plurality of bobbins 15, 16, 55. The frames 11, 12 are braced by a flanged body 10 keyed to a shaft 9-rotatable in a stirrup-shaped member 1 swingable about a shaft 3. As shown in Fig. 2 the working bobbin 55 is driven by a driving roller 18 and when the bobbin is full the operator pulls on the handle 32 to cause the frames 11, 12 to rotate about the axis 9 in a manner causing the next empty bobbin 16 to roll along a support device 17 terminating in the vicinity of the upper peripheral point 56 of the bobbin driving roller 18. The support device 17 ensures that when the operator has pulled the handle 32 sufficiently to cause the next empty bobbin 16 to pass vertically underneath the shaft 9 there will be no tendancy for the bobbin 16 to reverse back to its waiting position illustrated in Fig. 2. The handle 32 is used to rotate a control hub 33 carrying a spring biassed plunger 35 co-operating with a toothed control member 36. The control member 36 is coupled to the shaft 9 via outer clutch discs 47 associated with the stirrup 1 and inner clutch discs 48 associated with the shaft 9 to provide a damping and sliding coupling between the control member 36 and the shaft 9. The pressure exerted by the discs 47 and 48 is adjustable by means of an adjusting ring . threaded in the hub 33. The bobbins are mounted on rotatable receiving plates 13, 14 carried by the support frames 11, 12. Plate 13 is rotatably mounted in bearings carried in a recess in an axially movable spring box 26, a shift lever 30 movably mounted in a slotted guide in the housing 28 of the spring box serving to control axial movement of the spring box and its associated receiving plate.

Title: Improvements in and relating to the vacuum degassing of metal melts
IPC: C21C7/10
Filed: 1965-09-03
Abstract: In the vacuum degassing of molten metal an auxiliary gas is used which contains at least such a proportion of the gaseous impurities as a pure auxiliary gas would take up in one passage through the melt. The auxiliary gas may be recirculated through the melt until it reaches the maximum degree of contamination consistent with the degassing required; a part of the gas may be bled off and replaced with pure gas. The level of the metal above the auxiliary gas entrance may be so adjusted that the pressure of the gas introduced corresponds to the equilibrium pressure of the gas to be removed.

Title: Improvements in or relating to the heating of aircraft
IPC: B64D13/08
Filed: 1938-12-28
Abstract: 523,206. Heating aircraft. LAGABBE, E. DE Dec. 28, 1938, No. 37654. Convention date, Dec. 28, 1937. [Class 64 (ii) and 64 (iii)] In apparatus for heating aircraft by means of the exhaust gases, fresh air entering a pipe 1 is heated in a jacket surrounding a silencer having radially projecting hollow fins 3 formed of closely spaced pairs of parallel plates. The heated air passes through pipes 6, 7, 8 leading to various parts of the aircraft. Control valves 9 leading to the interior, and 10 leading to the exterior, may be interconnected so that as one opens the other closes. The pipes conveying the heated air terminate at the exterior of the aircraft at points of low pressure and the air inlets are at points of relatively higher pressure. Circulation in the aircraft is maintained by ensuring that the pressure within is lower than at the air inlet. Flow of air over the silencers is thus always maintained. Specification 343,662, [Group XXVII], and French Specification 680,595 and additions 38518 and 48902 are referred to.

Title: Improvements in and relating to automatic indicators for electrical bridge networks
Inventor: COPPARD ANTHONY HERBERT
IPC: H03M1/00
Filed: 1958-11-26
Abstract: 878,921. Electric selective signalling systems. SOUTHERN UNITED TELEPHONE CABLES Ltd. Nov. 26, 1959 [Nov. 26, 1958], No. 38126/58. Class 40 (1). [Also in Group XXXVI] Automatic indication of the value of an angularly variable component, as shown, Fig. 6, of a variable capacitor VC forming one arm of a bridge A, B, C, D, Fig. 1, is provided in a coded form by a circular digitizer DG, Fig. 6, coupled to the capacitor shaft and synchronously variable with the capacitance, so that the output of the digitizer, which is subsequently decoded and printed, gives an indication of the value of the capacitance VC, which is continuously varied, when it is of a value so that the bridge is in a " slightly off balance " condition. The latter is defined as that condition of the bridge which is so close to the balanced condition that, within the degree of accuracy of the digitizer the value of capacitance VC at that moment is effectively that corresponding to the balance condition. In Fig. 1, the potentials across arms AB, BC of the bridge are derived by subtracting transformers T1, T2, T3 and applied to a detector comprising differential amplifiers DA2, DA3 and signal generators SG1, SG2, the latter being triggered to give an output at said " slightly off balance " condition of the bridge, the outputs of the generators then being applied to a multivibrator MV which in turn produces an output pulse. In Fig. 6 a circuit as in Fig. 1 is used in the testing of quad telephone cables successively connected in circuit through terminals SC and a selector SS to form one arm of the bridge BR also including as another arm the variable capacitor VC. The detector and signal generators are shown at DE and, at the " slightly off balance " condition of the bridge the output pulse therefrom prepares gates amplifiers GA to allow the signal from the digitizer DG to pass to storage relays SR, decoder D and printer P. The capacity testing of the cables is not initiated until a signal from an insulation tester IT is received at the selector SS indicating that there is no insulation fault. The decoder consists of a relay system fully described in the Specification (Figs. 4 and 5, not shown). Digitizer (Figs 2 and 3).-The digitizer comprises at least one circular track which may be of electricity conductive portions separated by insulation and relatively rotatable with respect to at least one conductive brush, or alternatively as shown, the " conductive " portions may be transparent and separated by opaque spaces, the brushes being replaced by photovoltaic cells. The coding used is the Watts reflected decimal scale using the cyclic permuting binary code for digits 0-9 and similar additional scales for the decades 10-90 and for higher orders. Only 180 degrees of the digitizer scale is used representing 0-499. Three groups V, T, H of four tracks of contacts each, A-D, E-H and I-L are carried by the digitizer disc.
