Patent GB-1037984-A (GB)
Title: Halogenation of organic compounds
IPC: C07D233/82
Filed: 1963-08-19
Abstract: Halogenated organic compounds in which H attached to N or O is released by halogen, are made by electrolysing a mixture of the organic compound, water, and an inorganic halide which may be an acid, or a salt or a mixture thereof, at temperatures from -5 DEG  up to 80 DEG C.  Primary alcohols both aryl and alkyl, are thus converted to alkyl hypochlorites; primary and secondary amines to N-chloroalkyl amines and cyanuric acid to mono- or di-chlorocyanuric acid or salts thereof. The process may also be applied to form halogenated amides, imides, amines, imines, sulphonamides, ammeline, melamine, quanamine, and hydantoin. The mixture may be a solution or in the form of a slurry or dispersion using a diaphragm. The power applied is preferably a ripple or pulsed current whereby electrodes are depolarized.  Electrodes are mounted adjustably to control the area submerged in the electrolyte, and a range of suitable metals for the electrodes are specified e.g. graphite, Ti, Ta, and Pt.  A bipolar cell may be used, or a standard type cell containing up to 100 or more electrodes.  Conditions are, C.D. up to 2000 A.S.F., voltage 1.5 to 300, and pH preferably 4 to 10.  The electrolyte may be recycled outside the cell for cooling.  For examples, the inorganic halides used are preferably chlorides and bromides, but iodides and fluorides may be used e.g. KBr and HBr, CaCl2 and HCl, ZnCl2 and HCl, CsCl and HCl.  CuCl2 and MgCl2 may also be used. Conductivity may be increased when using a metal chloride alone by adding acetic or oxalic acid.

Filed: 1971-07-13
Abstract: 1363666 Expanded metal JURY & SPIERS PTY Ltd 13 July 1971 [16 July 1970] 32845/71 Heading E1K [Also in Division B3] A method of making expanded metal comprises at least partly perforating a ductile metal member 21 to form a plurality of rows 23 of identical slots 20 having curved ends, which are staggered with respect to the slots of adjacent rows, to form a series of stretchable portions between the rows, securing the member in jaws 28, 30 and forcing the jaws away from each other to strain the stretchable portions beyond their yield point and to indine them to the longitudinal axes of the rows of slots, Fig. 4 (not shown). The member 21, which may be of aluminium, is fed between rolls (11), (12), Fig. 1 (not shown) respectively provided with projections (13) and grooves (17) which co-operate to shear slugs 20 either partially or fully from the member 21. The partially sheared slugs are ejected as the metal is expanded. The rounded ends of the slots reduce stress concentrations during expansion and tearing of the metal is prevented if the end radius is not less than half the metal thickness. In an alternative embodiment, Fig. 6, an aluminium member 47 is formed with spaced longitudinally extending flanges 48 and projections 13 on rolls 41 completely shear the slugs 20. During expansion the members may tend to contract inwardly and this is prevented by inserting pins through some, at least, of the end slots, the pins engaging against restraining members in the stretching machine.

Abstract: 392,242. Mounting reflectors. MAINWARING, H., Inverleith, Oldfield Road, Bowdon, Cheshire. Nov. 27, 1931, Nos. 32860/31 and 6139/32. [Class 75 (ii).] Lamp reflectors are mounted so as to be angularly adjustable in two planes upon a support secured to a pipe or other fixed part, each reflector resting on an adjustable screwed abutment on a member which forms part of the support and being hinged to that member so as to be readily detachable without disturbing the setting. A bracket A is formed with a vertical part V having a curved central portion which fits around a vertical rod or tube, and a horizontal T-shaped part S, the leg of which extends outwardly and has a rounded end. An angle bracket B is pivoted by means of a screw F near the rounded end of the leg. Fixed at the corner of the bracket B is a rod G on which rotate rods T, T<2> which carry the reflector. The rod T is bent over to form an eye at its end, and the rod T<2> to form a hook, so that they, together with the reflector, can easily be engaged with or disengaged from the rod G. Adjustment in a vertical plane is obtained by means of a screw Z, which bears against the rear surface of the reflector and is locked in position by a nut J. A screw W passes through a hole in an upwardly projecting ear E<2> (not shown). The end of the screw is threaded to a smaller diameter and passes through a hole in a second ear E which is of a correspondingly smaller diameter, and a nut is threaded on the end, so that axial movement of the screw is prevented. A nut K threads on the main part of the screw, and has fixed to it a claw, the forked part P of which engages with a screw X in the bracket B. Rotation of the screw W causes axial movement of the nut K and claw, which rotates the bracket B. A nut may be provided on the screw W to lock it in position. A similar assembly is arranged so that the curved portions of the vertical parts V of the brackets A clasp the rod or tube which supports them. According to the first Provisional Specification, the reflectors are each hinged as described above to the outer edge of a flat metal member which is notched to enable angular adjustment in the horizontal plane about an angle bracket through the lower part of which passes a screw for adjusting the reflector at the required angle in the vertical plane. A pair of brackets, each with its associated flat metal member, are clamped to a supporting column.
