Filed: 1965-11-10
Abstract: <PICT:1108010/C2/1> A method of continuously transesterifying an ester of a dicarboxylic acid with an alcohol is performed in at least one open indirectly heated trough into and/or across which methanol vapour is passed which may be conducted in countercurrent or cross-current to the product.

Title: Improvements in or relating to shoe upper conforming machines
Inventor: QUARMBY ROBERT CHARLES
IPC: A43D23/02
Filed: 1964-11-25
Abstract: 1,126,051. Boots &c. BRITISH UNITED SHOE MACHINERY CO. Ltd. 24 Nov., 1965 [25 Nov., 1964], No. 47864/64. Heading A3B. In a lasting machine of the type in which the upper is tensioned about the last by grippers and is laid over the edge of the insole by wipers, the grippers release the upper when the wipers engage the grippers during their inwiping action to complete an electrical circuit which causes the gripper jaws to open. As described a lasting machine of the type described in Specification 1,010,149 includes two joint gripper units 32, 34, one at each side of the shoe, a pair of joint wipers 2 and an electrical control circuit (not shown) which causes the gripper jaws 32, 34 to open only when both wipers 2 are in contact with their associated gripper jaws 34. The gripper jaws 32, 34 are pivoted at 30 to an end portion of a cylinder 20 and are closed by the action of a wedge on the piston rod 42 which engages rolls 44 on the gripper jaws 32, 34. The gripper unit and cylinder 20 are carried on a piston rod 16 and are insulated therefrom by a collar 26 and bushes 24 of insulating material. A wire 82 connects the gripper unit to the electrical control circuit. The piston rod 16 has a piston 14 movable in a cylinder 12 which forms part 10 of a ball and socket joint 9. Actuation of cylinder 12 causes the grippers to lay the lasting margin of the upper U inwardly across the insole O. The grippers are lowered to tension the upper by the action of piston 52 and cylinder 50, the cylinder 50 being pivoted to the piston rod 16 and the piston rod 70 being pivoted to the bracket 6. The machine has an automatic control circuit and operates as follows:-when the lasting margin has been placed in the gripper jaws 32, 34 the jaws 32, 34 close and move downwardly under the action of piston and cylinder 50 to tension the upper. The jaws 32, 34 then move inwardly under the action of piston and cylinder 12 to lay the lasting margin against the insole I and the wipers 2 perform their inwiping . action. When both wipers 2 have contacted the jaws 34 to complete an electrical circuit a transistor (not shown) in the circuit becomes conductive and energizes a relay which in turn operates a solenoid operated valve to cause the jaws 32, 34 to open. The grippers then move to their inoperative position and the wipers complete their inwiping operation.

The table is then stepped a further 90 degrees where another gauge (not shown) measures the diameter 14 and moves the plunger 20 if the diameter 14 is incorrect and if the plunger has not already been moved. A further rotation of the table takes the article to a position where the plunger 20 may move a roller 26 to operate the switch 28 of a reject mechanism If the article is acceptable however then the plunger is not moved, the reject mechanism is not operated and the article is carried further where it is pushed off the table into a chute 30 by a ramp 29. A re-set ramp 31 restores any operated plunger 20. In a modification the table is replaced by a drum or straight conveyer and the mechanism may be arranged to grade the articles into different dimensional groups.

Abstract: 1307507 Fuel elements WESTINGHOUSE ELECTRIC CORP 20 Oct 1971 [8 Dec 1970] 48788/71 Heading G6C [Also in Division B3] A nuclear fuel element is provided with an axial bore 9 in an end plug 7 and is introduced into a chamber containing an inert gas under pressure prior to the sealing of the bore 9 by welding. By this means, a fuel element containing gas under a pressure of 500 to 1900 p.s.i. may be obtained. The pressurizing gas should provide a good atmosphere for welding, helium being preferred while other suitable gases include argon, and helium-argon and heliumxenon mixtures. The fuel element cladding 3 and end plug 7 may be formed of a Zr-alloy or stainless steel. The welding electrode 47 is preferably of a material similar to that utilized for the plug 7 and has a tapered or conical end extending into the bore 9 of the plug 7, with which it makes line contact. On passing electric current through the electrode 47 and the plug 7, the high contact resistance between the electrode and the plug causes rapid heating and subsequent melting of the electrode point. As the electrode melts breaking the metallic welding circuit, an instantaneous high-current arc is formed between the remaining solid electrode and the plug which further melts the electrode tip. Molten electrode material drops into and closes the bore 9. Electrode melt back creates a large gap which extinguishes the arc. Because of the very short duration of the arc it is referred to as "instantaneous". After solidification of the fused material, the completed fuel element is removed from the pressurized gas chamber.

An electrophotographic material has an electrically conductive support bearing a photoconductive layer which contains a photoconductor having the structural formula in which A represents a divalent aromatic radical, mono- or polynuclear, substituted or unsubstituted; A<SP>1</SP> represents a monovalent aromatic radical, mono- or poly-nuclear, substituted or unsubstituted; Q represents a hydrogen atom, a halogen atom, or an aromatic group A<SP>1</SP>NH-; G represents a hydrogen atom, a poly-(4-vinyl)-phenyl group, or an aromatic radical, mono- or polynuclear, substituted or unsubstituted; and n is an integer 1 to 12 such that the photoconductor always contains at least two amino nitrogen atoms. Such a photoconductor may be made by reacting a diaryl secondary amine with an aryl halide. Links of suitable halides and amines are given. Aryl halides, aryl polyhalides, and aryl polyhalides in which the haloaryl group is an appendage to a linear polymeric backbone (e.g. a polyhalostyrene) are useful. Chlorides, bromides, and iodides are the preferred halides. When chlorides are used the reactants may be simply heated together under pressure, but with bromides and iodides the condensation is best carried out in an alkaline medium, such as a nitrobenzene solution of potassium carbonate, and with a powdered copper catalyst. Whether the products are polymeric or non-polymeric depends on the functionality of the reactants and on whether or not one of them is itself a polymer. The preparations of some specific compounds are described. The photoconductors may be used with or without an organic binder. A list of suitable binders is given. A list of optional sensitizing compounds is given which includes both dyestuffs and non-dyestuffs. The preferred sensitizers are fluorenes, carboxylic acids, triphenylmethane dyes, and pyrylium and their pyrylium salts. The results of exposure tests are given for six materials each having an aluminium foil supported layer containing a specified polyester binder, a specified thiapyrylium perchlorate, and a respective one of six photoconductors. Specification 998,642 is referred to.
