Title: Improvements in or relating to the production of isoprene
IPC: C07C4/10
Filed: 1958-11-21
Abstract: Isoprene is prepared by isomerizing an n-hexene to an isoprene precursor and pyrolysing; an isoprene precursor is a branched chain hexene which cracks to give isoprene as the major product, e.g. 2-methylpentene-2; 3-methylpentene - 2; 2 - ethylbutene - 1; 2,3-dimethylbutene - 1; and 3,3 - dimethylbutene-1. Isomerization is effected over acidified alumina, acidified clay, alumina-hydrofluoric acid or phosphoric acid on alumina or silica at 150-700 DEG  C. at an LHSU of 0.5-20 and a pressure of 1 mm.-1 atmosphere or higher. Further isomerization of branched chain hexenes which are not isoprene precursors but are obtained by the isomerization of n-hexenes with or without intermediate separation by treatment with alumina, silica-alumina, nickel, acidified alumina, acidified clays, alumina-hydrofluoric acid, alkyl sulphonic acids, aryl sulphonic acids, aralkyl sulphonic acids, perchloric acid, phosphoric acid or sulphuric acid at - 50 DEG  to 700 DEG  C. and 1 mm.-3 atmospheres pressure and a LHSV of 0.5-20.  Pyrolysis is effected by heating the isoprene precursor or mixture of precursors to 550-1000 DEG  C. for 2.0-0.001 seconds. Specification 832,475 is referred to.

Patent GB-385958-A (GB)
Abstract: 385,958. Copying-telegraphy. DUBILIER CONDENSER CO. (1925), Ltd., Ducon Works, Victoria Road, North Acton, London.-(Assignees of Nyman, A. ; 10, East 40th Street, New York, U.S.A.) April 2, 1931, No. 10103. Convention date, April 3, 1930. Void [Published under Sect. 91 of the Acts]. [Classes 40 (iii) and 40 (v).] Picture signals of varying amplitude are converted into impulses of constant frequency and amplitude but varying duration. Light from a source 3, Fig. 1, is interrupted at 6 and falls on a picture drum 1, where it is reflected to a photo-electric cell 9. The resulting impulses of constant frequency but varying amplitude are fed to a valve 10 whose grid is biased so that no current passes through it when the cell is not illuminated. A condenser 15 in the output of the valve 10 is in parallel with a galvanometer 14 which allows either all or none of the light from a source 17 to pass through apertures 16 in the magnet system to a cell 30. It is shown that the cell 30 generates impulses of constant amplitude and frequency, but of varying duration in accordance with the light falling on the cell 9. By shunting the condenser 15 by a resistance 41, Fig. 5 (not shown), the cell 30 may be illuminated when the cell 9 receives no light from the drum 1, or the valve 10 may be biased so that for zero light intensity from the drum 1 the valve is conducting and the condenser 15 is charged, Fig. 3 (not shown). In this latter system, the dark periods produced by the interrupting disc 6 may be made very small. In the arrangement of Fig. 6, two valves 55, 56 are negatively and positively biased by batteries 57, 58 respectively. A battery 63 and a resistance 64 are connected in the output circuits of both valves, and a condenser 15, in series with the galvanometer 14, is in parallel with the resistance 64. During the period of charging the condenser, the valve 56 is ineffective because of its negative grid bias and the charging period is lengthened. The discharging period is similarly shortened since the current through the valve 6 is then large, this valve acting as a resistance in parallel with the condenser 15. The frequency of the impulses of constant amplitide but varying duration may be used for synchronizing.

Title: Improvements in or relating to multi-spindle automatic lathes
IPC: B23Q16/06
Filed: 1956-12-20
Abstract: 808,889. Automatic multi-spindle lathes. WERKZEUGMASCHINENFABRIK GILDEMEISTER & CO. A.G. Dec. 20, 1956 [Dec. 24, 1955], No. 38831/56. Class 83 (3). A device for stopping the spindles of an automatic multi-spindle lathe in a predetermined position comprises magnetic-clutch means which first imparts a " creeping " movement to the spindle on operation of switch means by a control drum, the selected spindle being subsequently stopped by the automatic displacement of a locking member which, upon engagement, de-energizes the magneticcoupling of the " creeping " drive. The spindles 1a, 1b of a six-spindle automatic work-turret lathe are driven for normal operations by a central gear driving spindle gears 2; the drive to the central gear is not described. The gears 2, Fig. 1, rotate freely about the spindles until clutches 3 are closed by a sliding ring 4 operating clutch levers through a cone-shaped recess in its end. The sleeves 4 rotate with the spindles and are provided with grooves engaged, in the positions while the spindles are to be stopped, by members 8 secured inside a ring 7 surrounding all the spindles. The ring is moved to operate the clutches by levers 9, 10, and a cam drum 14 carried on an auxiliary timing shaft 13 of the machine. When the ring 7 is moved to the left to release the clutches 3, the near faces 41 of the sleeves 4 are brought into close proximity to covers 22, rotatably arranged over stationary electromagnetic devices 27 aligned with the machine spindles. The covers 22 are rotated at a very slow speed from an electric motor 23, driving through epicyclic gearing 24. Dogs 33, 33a on a switch drum 21 secured to the auxiliary timing shaft 13 operate switches so that, on disengagement of the spindle drive clutches 3, one or a pair of workspindles (as described in the example) may be stopped. The work-spindles to be stopped are brought to the positions 1a, 1b shown in Fig. 2 and the electromagnetic devices 27 brake the spindles concerned until they are finally rotating at the speed of the covers 22. Locking plungers 15, 16, hydraulically operated from solenoidcontrolled valves, are moved forward to engage recesses 6 in the spindle sleeves 4 to halt the latter. The plungers, as they move forward, operate switches 30, 31 to interrupt the current to the electromagnetic devices 27.

Abstract: 952,714. Flexible conduits. ACME-HAMILTON MANUFACTURING CORPORATION. Oct. 16, 1962 [Oct. 18, 1961], No. 39171/62. Heading F2P. A flexible conduit comprises a helical reinforcement having longitudinally-spaced convolutions and an enclosing cover therefore consisting of braided, contractile, plastic monofilaments, the cover being shrunk in situ to provide helical wall portions extending radially inward between successive convolutions of the reinforcement, the latter being in unbonded relation to the cover and non-displaceable relative to the cover upon flexure and twisting of the conduit. As shown, the precoiled reinforcement is of aluminium, steel or coppercoated steel wire, or a plastic such as polypropylene, and the cover monofilaments are of linear polyethylene, polypropylene, nylon or other tough plastic material having a high modulus. There may be an inner and/or outer sheath, of vinyl copolymer or polyvinyl chloride pigmented to a selected colour, or colourless and transparent; a helical space 32, Fig. 5, is provided between the braided cover and the sheath. The braided cover 13 may be rendered impervious to fluids by applying to the inner surface thereof a plastic coating in the form of a plastisol or organosol of vinyl copolyer, polyvinyl chlorides or polyvinyledene chloride or the monofilaments may be close braided and fused together. The reinforcement may comprise a pair of electrical conductors coiled helically in side-by-side relation and retained in insulated relation by the corrugation of the cover; alternatively, the wires are coated with polyvinyl chloride. The spacing between the braided monofilaments may be increased so that upon heating of the conduit assembly the sheaths 36, 37, Fig. 8, may be adhered together. In making the conduit, the helix 11 is moved upwardly from a coiler 15 to a braider 17 to pass through a nipple 19 on which the monofilaments are braided, the resultant braided covering passing through a stabilizing ring 19A. The assembly of helix and cover is passed through a hot-air-circulating oven to produce contraction of the braided covering and the helical wall portion 25.

A circuit-closer for rapidly short-circuiting two connection points, e.g. of a converter, and operable by a mechanism which can be released from a point at earth potential, includes a container 1 at high potential filled with compressed gas (air or electro-negative gas) and containing two stationary electrodes 5, 6 having well-rounded surfaces facing each other and being connectible by a movable contact 7 which is axially displaceable through electrode 6 into a recess 8 forming a socket contact in electrode 5. Two such movable contacts 7 have a link system 12 operated by upwards movement of an insulating rod 13 under the force of compressed gas in the mounting insulator 2 acting on a driving piston 17 of rod 13 to close the contacts 7, 8, upon a release impulse being sent to the coil of a retaining magnet 15 acting on an armature 14 attached to rod 13. The circuit closer is opened by momentarily placing a return piston 18 in earthed base 3 under pressure by supplying compressed gas through an opening 19 to the space above piston 18. The release impulse is alternatively supplied and transmitted from earth to high potential via an insulating transformer 20, Fig. 2, magnet 15 then being at the high potential and armature 14 being connected directly to the link system without the rod 13. Compressed gas container 21 supplies gas via a heating element 24 and the mounting insulator 2 to the container 1. Contacts opening is by momentarily connecting the space below the return piston 18 to the open air through insulator 23 and three-way valve 22. An indicator 25 is provided to show the position of the contacts. In a further embodiment, Fig. 3, the release impulse is supplied via insulating transformer 20 to an explosive charge 28 built into the hook of a mechanical latch 27. The contacts 7 are then moved by driving pistons 29 and retarded by damping piston 30 when they reach closed position. Flexible conductors 32 connect the hemi-spherical electrodes 31 and the metal container 1. For contacts closing one side of the driving piston 29 is connected with the open air through insulator 23 and valve 22, and to re-open the contacts this space is placed in communication with the compressed air container 21 such that contacts 7 are moved to open position and held there. Multiple circuit-closers have several such switching devices in series connection with the voltage distributed evenly by means of parallel impedances. Adaption as circuit-openers is referred to.
