Title: Processes for the isomerisation of waxy hydrocarbons
IPC: C10G45/62
Filed: 1955-03-28
Abstract: A hydrocarbon mixture containing at least 20 per cent by weight of waxy hydrocarbons is catalytically isomerized by subjecting a solid catalyst which is capable of effecting isomerization of the hydrocarbon mixture to a conditioning treatment which consists in heating the catalyst to a temperature of at least 250 DEG  C. in the presence of hydrogen under increased pressure, and then contacting the hydrocarbon mixture in the presence of hydrogen at 300-550 DEG C. and under increased pressure with the catalyst.  The hydrocarbon may be paraffin wax, or natural or synthetic hydrocarbon fractions which contain at least 20 per cent and preferably 50 per cent of waxy hydrocarbons.  The catalyst is preferably one having not more than 1 per cent by weight of platinum supported on a carrier such as alumina containing a small percentage of chlorine or fluorine.  Other catalysts such as those described in Specification 750,205 may also be used.  The conditioning treatment may be effected by heating up slowly to 250 DEG  C. and then maintaining the pressure at 25-100 atmospheres, up to 10 hours.  Isomerization is preferably effected at 400-440 DEG C. at 20-40 atmospheres, a contact time of 0.5-10 minutes, and a throughput rate of 1-5 Kgs. of starting material per litre of catalyst.  Specifications 713,910, [Group III], and 755,105 also are referred to.

Abstract: 567,805. Feeding molten thermoplastic material into moulds. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., and RICHARDSON, A. B. F. G. June 11, 1943, No. 9442. [Class 87 (ii)] Apparatus for feeding thermoplastic material in a heated viscous-liquid state under high or low pressure into moulds comprises a steamheated reservoir 1 and a hydraulic press 9, both the reservoir and the press communicating with a pipe-line 14 which leads to the moulds. In operation, the valve 17 being closed, the material is introduced into the reservoir, the interior of which is under super-atmospheric nitrogen pressure, through an aperture normally closed by a plug 2, the plug is replaced, the reservoir is evacuated of gas through a valve 41, and vacuum is maintained during the melting period. The valve 41 is then closed, nitrogen under pressure is admitted to the reservoir from container 10, valve 17 is opened, and the material is thus forced through pipe 14 into a chamber 18, where it raises a hydraulic ram 24. The material passes on through the pipe 14 to nozzles 31, whence it may be admitted as required through valves 32 into moulds clamped to the nozzles by screw spindles 35. To exert a high pressure, the valve 17 is closed and the ram 24 is depressed to force material into the moulds. The ram may be raised, for cleaning the chamber 18, by a chain 45. A steam supply 5 heats the reservoir 1, the pipe 14, the ram 24, the chamber 18 and the nozzles 31. In a modification, the reservoir includes a screw conveyer, which may be used instead of or in conjunction with either the ram or the gas pressure.

Title: Balling apparatus for slivers of textile material
IPC: B65H61/00
Filed: 1961-03-15
Abstract: 921,914. Sliver balling apparatus. WARNER & SWASEY CO. March 15, 1961 [April 28, 1960], No. 9465/61. Classes 120 (1) and 120 (2). Balling apparatus for slivers has an arbor mounted on arms rotatably carried on a support member to permit pivoting of the arms during build-up of the ball and in which the support member is rotatably mounted to move the arbor between balling and doffing positions. The arbor 17 is carried on arms 20 pivoted at 23 to a support member 22 mounted on a rotatable splined shaft 65. Rotation of the arbor 17 or of a sliver ball upon it is derived from a driven drum 18. Sliver delivered by a gill box passes between rollers of a yardage counter that are arranged to actuate a switch to stop the gill box drive motor and start a reversible doffing motor when a predetermined amount of sliver has passed. Doffing begins with the lowering of arbor 17 by rotation of splined shaft 65 and the two portions into which the arbor 17 is equally divided axially are then caused to separate to release the ball. Consequential on the separation of the arbor halves, a second switch is actuated that reverses the doffing motor but the gearing driven from the motor is arranged to provide a dwell during which the released sliver ball after rolling down a shoot 103 passes into a drum 101 that, simultaneously with the lowering of the arbor 17, was turned a half revolution so as to receive the ball through an opening in its periphery. After the dwell, the halves of the arbor 17 are raised and brought together and the drum 101 makes a half revolution. As the drum 101 turns, the length of sliver extending between the ball and the gill box is raised by the leading edge of the periphery of the drum and is also gripped between the inner ends of the arbor halves resulting in severance of the sliver between the arbor and the drum. The return movement of the splined shaft 65 and member 22 is such as to lay the arbor 17 upon the driving drum 18 in readiness for the formation of a new roll. A safety switch 133 adjacent the drum 101 and operated by the weight of a ball in the drum prevents a further doffing cycle until the ball has been removed from the drum. Sliver is traversed on to the arbor by mechanism such as is described in Specification 917,072 and it is desirable that the traverse guide be located opposite the position at which the sliver is gripped by the half-arbors at the beginning of ball formation. To this end means are provided for sensing the position of the sliver guide and locating it at the desired position as doffing proceeds, such means form the subject of Specification 921,915.

The solvent is preferably a reactive solvent, i.e. one which under the setting conditions increases its molecular size either by self-condensation or by reaction with the partially etherified methylol phenols. Suitable reactive solvents are phenol, a cresol, benzaldehyde, benzyl alcohol, epichlorohydrin, a glycerol chlorohydrin or dichlorohydrin or a furan derivative, e.g. furfuryl alcohol or furfural. Suitable acid catalysts are H 2 SO 4 , HCl, H 3 PO 4 , a sulphonic acid, an acid ester of sulphuric acid, a sulphonic acid ester and/or a sulphonyl chloride. The weight ratio of the solution of the partially etherified methylol phenols to cement powder is preferably from 1:1 to 1:7 and the solution of partially etherified methylol phenols preferably has a solids content of 50-90% wt. The alkylphenol is preferably an o- or p-alkylphenol, the alkyl group of which has 1-20 carbon atoms and is linear, branched or cyclic, and optionally substituted by an aryl group; e.g. it may be an aralkyl phenol which is an addition product of a vinyl aromatic hydrocarbon to phenol. Suitable etherifying agents are dialkyl sulphates, diazomethane, halogen-containing alkanes, alkenes or ketones, an epoxide, a halohydrin or other halogen-containing alcohol or mixtures thereof. The cement composition may be applied between or on the materials to be cemented together and hardens at temperatures of 15-35 C. The compositions can also be used in the manufacture of acid-resistant flag-stones and masonry. In the examples cement compositions are prepared by dissolving in furfural a resol resin mixture prepared either (1) by first reacting phenol with styrene in the presence of concentrated H 2 SO 4  and then with aqueous HCHO in the presence of NaOH and then with propylene oxide, followed by neutralization of the catalyst with H 2 SO 4 ; or (2) by first reacting p-tert-butylphenol with aqueous HCHO in the presence of NaOH using toluene as solvent and then adding phenol, aqueous HCHO and more NaOH, and further reacting, and then reacting the resultant mixture with propylene oxide, followed by neutralization as in (1) above, and mixing the resultant resin solution with a cement powder containing powdered coke and benzenesulphonyl chloride. The compositions are moulded into test articles.
