Title: Method and apparatus for shaping the ends of composite and other candles
IPC: C11C5/02
Filed: 1949-10-03
Abstract: <PICT:0670133/III/1> <PICT:0670133/III/2> In the shaping of the ends of candles wherein the end of the candle is pressed into a heated mould and the excess of candle material is melted off and drained, a reduced pressure is provided in the heated mould to ensure the discharge of melted material. Preferably the vacuum is automatically created between the bottom of the mould and the end of the candle by providing tightness at the bottom of the mould at the beginning of the removal of the candle therefrom.  The mould is desirably conical and grooved so that the shaped foot of the candle acquires the shape of a truncated cone with roof-shaped ribs 23.  A suitable apparatus comprises a mould 3 surrounded by electrical heating elements 4 within a casing 5 and centrally apertured bottom plate 1.  A superimposed cooling jacket 6 with a central opening 7 registering with the opening in the mould for the reception of the candle is provided, so that the heating of the end of the candle is limited to a pre-determined height.  The mould is tapered downwardly and has grooves 10 increasing in width towards the bottom where the grooves meet.  This bottom is closed by a loose closure preferably of the form of a piston head 14, the rod 15 of which, guided by a bushing 17, is pressed by a spring 16 so that the closure 14 abuts against an inside edge 13 of the mould.  The piston and bushing are arranged within a recess 12 where melted material from the candle collects on the pressing down of the piston head 14 by the candle, the melted material flowing through apertures 18 in the bushing 17.  The upper edge of the mould is provided with jags 19 and scallops 19' therebetween, the material removed by the jags when the candle is inserted flowing down outside bevel edges 20, 21 to a number of vertical channels 22 extending to the bottom of the mould.  On removal of the candle the piston head 14 closes the bottom of the mould and on continued withdrawal of the candle a partial vacuum is created to which melted material is sucked down.  Using the above apparatus the shaped foot of the candle is conical with roof-shaped ribs 23 increasing in width to the end of the foot where the ribs meet; scallops 24 appear at the transition between cylindrical and conical parts of the candle.  A number of such moulds may be used for shaping the ends of a number of candles removed from a battery of moulds in a candle moulding machine.

Abstract: 848,082. Positive clutches; clutch control. MEINELT, A. Aug. 22, 1956, No. 25687/56. Class 80 (2). [Also in Groups XXVIII and XXXIV] In a lubricating pump of the kind having pistons of lubricant delivery devices 44 driven by cam discs 14 for supplying a plurality of lubricating- points, a device 22 for controlling the delivery of lubricant to a two-line system is fitted to the pump casing and the pistons 25, 26 of said device are also driven from the cam discs 14. A lubricant tank is mounted on top of the pump casing 1 and lubricant is fed from the tank to the casing 1 by a feed-screw (not shown). The cam discs 14 are secured to a shaft 10 which is driven by a worm 15 and worm-wheel 16. The feed-screw is driven from the shaft 10 through bevel gears 17, 18 and a vertical shaft 19. A gearwheel 20, keyed to the shaft 19, drives, by way of an intermediate gear-wheel, the pinion 30 of the control device 22 comprising a change-over piston 28 which, in its left-hand position, allows lubricant from the conduit 38 to flow into the main feed-line II and, in its right-hand position, causes the lubricant to flow into the right-hand line I. The pinion 30 is mounted rotatably on a shaft 29 which carries an eccentric pin 31 engaging a slider 32 for effecting rectilinear movement of the piston 28. A'clutch between the pinion 30 and shaft 29 comprises a wedgemember 33, located in a groove in the shaft 29, the nose 62 of the member 33 being biased in the anti-clockwise direction by a spring 55. Engagement of the nose 62 with a recess in a bush 42 carrying the pinion 30 is normally prevented by a detent member 43. On rise of pressure in the main lubricant line II, the detent is lifted clear of the clutch member by a piston 37 lifting a yoke 35 from which the member 43 is suspended and the clutch becomes engaged for half a revolution of the shaft 29 whereby the change-over piston 28 is moved to the right-hand end of its cylinder. Disengagement of the clutch is effected by subsequent rise of the yoke member 35 which actuates a pressure-release valve 36. The change-over piston 28 is coupled rigidly to an auxiliary piston which facilitates pressure release in the system.

Patent GB-906743-A (GB)
Title: Trialkyl aluminium complexes and production of alpha-olefins
IPC: C07F5/06
Filed: 1960-07-26
Abstract: Alpha olefins are obtained by reacting a C2-C4 aliphatic mono-1-olefin with AlR3 or AlR2OR1 + AlR3 or AlR2SR1 + AlR3, in which R is a C1-C4 alkyl group and R1 is a hydrocarbon group, to form a growth product, reacting the growth product with a further amount of the olefin in the presence of a metallic reducing agent and adding to the resultant displacement product a complexing agent for trialkyl aluminium which is an alkali metal cyanide, a complex of an alkali metal cyanide with a trialkyl aluminium, or an aromatic ether, thioether or tertiary amine in sufficient amount to form a complex with all the trialkyl aluminium present.  Optionally when an aromatic ether, thioether or amine is used as the complexing agent there may also be added an isomerisation and reverse displacement inhibiting amount of an alkali metal cyanide or complex thereof with a trialkyl aluminium in an amount of 5-200 parts per part by weight of catalyst. When a cyanide complexing agent is added the complex is formed by heating to 50-150 DEG C. for 1-30 minutes, the mol ratio of trialkyl aluminium to cyanide being adjusted to between 1.5 and 2:1. Alternative complexing agents are diphenyl ether, dibenzyl ether alkoxynaphthalenes, anisole, substituted anisoles or phenetoles, or dimethyl aniline.  The growth reaction is effected conventionally employing a C2-C4 olefin and triethyl aluminium, tripropyl aluminium, tributyl aluminium or triisobutyl aluminium at 65-150 DEG C. and 200-5,000 p.s.i.g.  Displacement is effected at 50-150 DEG C. for 1-30 minutes with an additional amount of olefin in the presence of cobalt or nickel added as finely divided nickel, Raney nickel, nickel acetylacetonate or nickel naphthanate.  The complexing agent preferably causes two phases to separate, olefins and complex, and these are separated; olefins are recovered and the complex is decomposed to recover trialkyl aluminium which is reused.  If growth is effected on AlR2OR1 or AlR2SR1 in the presence of AlR3, these compounds remain with the olefins and are separated by distillation. Complexes of trialkyl aluminiums and alkali metal cyanides have the formulae Me(1.5AlR3)CN and Me(2AlR3)CN where Me is an alkali metal, e.g. lithium, sodium or potassium and complexes with mixed alkali metals have the formula Me1xMe2y(1.5AlR3)CN and Me1xMe2y(2AlR3)CN where Me1 and Me2 are different alkali metals and x + y = 1, e.g. Na0.5K0.5(1.5Al(C2H5)3)CN and Na0.5K0.5(2Al(C2H5)3)CN.  The complexes are prepared by heating the ingredients in the necessary proportions at up to 150 DEG C. for 1-30 minutes.  Addition of trialkyl aluminium to the 1.5:1 complex also produces the 2:1 complex and addition of cyanide to the 2:1 complex yields the 1.5:1 complex.  The complexes are decomposed by heating at 100-200 DEG C. and 1-500 mm. mercury pressure.  Complexes of trialkyl aluminiums with ethers, thioethers, and tertiary amines as referred to above are also described and the separation of trialkyl aluminums from olefins by forming complexes is described. Specification 906,744 is referred to.
