Title: Vertical lathe for the turning of parts of non-circular section more particularly ofingots of pyramidal shape
IPC: B23Q35/08
Filed: 1936-01-30
Abstract: 469,674. Lathes. SOC. ANON. DES ANCIENS ETABLISSEMENTS C. BERTHIEZ Jan. 30, 1936, No. 2871. Convention date, Aug. 28, 1935. [Class 83 (iii)] Ingots a or other work pieces of non-circular section are turned on a vertical lathe provided with tool holders which have a vertical feed motion in addition to a transverse reciprocating motion in unison with the work rotation. The columns d of the machine are connected by a member dl containing the tail centre. Each column carries a slide rest e, fed by a vertical screw el and nut e5 and fitted with a tool carrying cross slide f. The cross slide movements are controlled by a cam g shaped in accordance with the cross section of the work splined on a vertical shaft g<1> and moving vertically with the rest e. The work table b and the feed mechanism are operated from a motor h, this mechanism including a change speed gear box e<4>. Each column d carries an angularly adjustable slotted guide rail i set according to the taper of the work a and engaged by a slide i<2> connected by a ball-ended sliding rod to a double-armed lever k, k<1> pivoted on the shaft g. A rod m<2> fixed in the rest e carries a slidable member m to which is pivoted at l<2> a lever l actuating the cross slide f. The lever l is slotted at l<3> to receive a roller o on the trunnion o<1> of a member o<2> which slides along the rod p and carries a second roller q engaging a slot k<3> in the lever arm k<1>. The roller n engages the driven cam g so that as the cam rotates the lever l is rocked about the trunnion o<1> to impart the peripheral profile to the work. Also during the vertical movement of the rest e, the guide i operates the lever k, k<1> to alter the position of the trunnion and impart the necessary tapering movement to the cross slide f. Movement of the trunnion o also alters the relative lengths of the arms of lever l so that the transverse stroke of the cross slide is constantly altered. If the tapering movement is not required the guide rail i is adjusted to a vertical position.

Abstract: 1496330 Coating apparatus UNIVERSITY OF STRATHCLYDE 27 Dec 1974 [23 Jan 1974] 03068/74 Heading B2L Charcoal or other particles are coated electrostatically with a liquid coating composition in an insulated vessel 1 which is rotatable by a motor 7 about an inclined axis. The particles are charged by an electrode 12 or by rolling friction in the rotating vessel and a film forming solution, is brought into contact with the particles. The apparatus in Fig. 1 includes tubes 10 in a fixed cover 9 for charging and discharging particles and for passing drying gas, tubes 11 for charging and removing coating solution and a brush 13 with a switch 14 for discharging the electrostatic charge. In use, after charging the particles, solution is introduced to coat the particles and then excess removed before drying gas is circulated in the vessel 1. The vessel is tilted to discharge the coated particles. In the modified apparatus in Fig. 3 gas entering by pipe 22 is heated by a heater 27 to evaporate solvent from the coating solution after coating and is vented through a pipe 21, solvent vapour condensing on condenser 23 and flowing into a trap 24.

A process for the production of mixtures containing bis - (2 - hydroxyethyl)-terephthalate and its oligomers, comprises heating diammonium terephthalate in a stream of an inert gas with an excess of ethylene glycol at a temperature in the range 160 to 260 C. in the presence of an esterification catalyst selected from a compound or mixture of compounds of metals of the IIB, IVA, IVB and VA groups of the Periodic Table according to "The Chemical Dictionary", 7th edition, published by the Reinhold Publishing Co., soluble in the reaction mixture, the reaction being performed with a 3 to 20 fold molar excess of ethylene glycol until 10 to 60% of oligomers of the bis-(2-hydroxyethyl)-terephthalate are formed. The monomer and oligomers are purified by fractional crystallization from ethylene glycol or by removing the ethylene glycol by vacuum distillation, dissolving the solid residue in a suitable solvent, e.g. water, and separating the monomer and oligomers by fractional crystallization. The distillation residue or the purified and recombined monomer and oligomers may be worked up to yield polyethylene terephthalate by processes described in the literature.

An injection moulding machine for thermosetting plastics materials, which may be mixed with glass or textile fibres, comprises a piston 3 working in a cylinder 1 from which it displaces material through a nozzle 2 into a mould 10, the piston having a smaller outer diameter than that of the bore of the cylinder, and having a collar 5 of flexible material e.g. uncured rubber or a synthetic plastics material, attached to it to provide a seal with the cylinder wall, the collar being of such material that the heat generated by friction between it and the cylinder is less than that which would cause setting of the thermosetting plastics material in the cylinder 1. The machine is preferably operated hydraulically, a series of moulds being mounted on a rotating table (not shown). The cylinder may be fitted with a flexible metal e.g. steel sleeve 12 which can be filled before insertion in the cylinder 1. A plurality of cylinders 1 may be mounted round a rotatable shaft so that each cylinder in turn can be brought into alignment with the piston 3, a piston 16 pressing the cylinder against the nozzle 2 to prevent leakage of material during the forward stroke of the piston 3. After filling of each mould the piston is withdrawn momentarily to sever the material at the nozzle 2 prior to withdrawing the cylinder and piston unit.

Title: Manufacture of acetyl chloride
IPC: C07C51/58
Filed: 1953-02-10
Abstract: Acetyl chloride is prepared by passing methyl chloride and carbon monoxide at a temperature above 600 DEG  C. and under atmospheric or superatmospheric pressure through a reaction vessel which has a smooth and heat-resistive internal surface which is non-metallic and in the walls or interior of which vessel no catalyst for the reaction is present.  The reactor may be an empty ceramic tube, the inner surface of which is preferably glazed.  Desirably, the reaction mixture is preheated to about 700-800 DEG  C. and the reactor is heated to about 800-900 DEG  C.  If the reaction is incomplete, the gaseous mixture may be recycled. The acetyl chloride may be recovered by extracting the gaseous products with an inert solvent, e.g. acetic anhydride, and then distilling the solvent to recover the acetyl chloride.  An improved conversion is obtained if the reaction product is immediately cooled by contact with a cold surface which may be an internally cooled metal tube placed in the outlet of the tubular reactor.  An example is given.
