Title: Improvements in or relating to overload devices for the protection of polyphase electric circuits and apparatus
Inventor: DAVIES JOHN STANLEY
IPC: H01H71/10
Filed: 1958-11-19
Abstract: 892,887. Electrically - released switches. BROOKHIRST SWITCHGEAR Ltd. Nov. 6, 1959 [Nov. 19, 1958], No. 37164/58. Class 38 (5).  A polyphase protective device comprises a laminated bar in which relative movement between the laminations 10 ... 12 is normally prevented by detents 15 ... 17 under the control of electromagnets 22 ... 24, failure of the current in any of the electromagnets causing the release of the associated detent and movement of the associated lamination to actuate or cause the actuation of contacts 25. The laminations are supported on pivoted arms 13 and biased by springs (not shown). When current is switched on to the protected apparatus, the electromagnets, under normal conditions, are all energized and the detents and laminated bar are rocked collectively about the axis 18 without relative movement between the laminations. Should there be a failure in one of the phases, the electromagnet associated with that phase will not be energized and the associated detent will not be rocked with the others when the current is switched on, or will be released by gravity or a spring (not shown) if the failure occurs during operation of the apparatus. In either case the detent 15, 16 or 17 is released from a lug 10a, 11 a or 12a on the associated lamination so that the lamination moves longitudinally under the bias of its spring to trip the contacts 25. The device is reset by the operation of a push-button 26. Specification 892,888 is referred to.

Title: New diphenylether derivatives and process for the preparation thereof
Inventor: WILKINSON JOHN HENRY
IPC: C07C59/70
Filed: 1955-12-29
Abstract: The invention comprises diphenylether derivatives of the general formula <FORM:0805761/IV (b)/1> (wherein R2 is a hydroxyl group, or a group readily convertible thereto, for example an acyloxy or alkoxy group, and R3 is a group readily convertible to an acetic acid sidechain as defined below) and a process for the preparation thereof by reacting a quaternary salt of the general formula <FORM:0805761/IV (b)/2> (wherein R4N is a tertiary base which is aliphatic, partly aromatic, or in which the nitrogen is part of a heterocyclic ring and X is the anionic portion of an aromatic sulphonic acid, hydrochloric acid, hydrobromic acid or hydriodic acid) with a phenol of the general formula <FORM:0805761/IV (b)/3> Groups readily convertible to an acetic acid side-chain are -CH2COOR (R is alkyl), -CH2Cl, -CH2Br, -CH2CN, -CH2OH, -COCH3, -CHOHCH3, -CH = CH2, -CH2CH = CH2, -CH2CHOHCH3 and -CH2COCH3.  The reaction is preferably carried out in the presence of a solvent, those having a dielectric constant less than 25 being particularly suitable, or an excess of the base R4N; the anion X is preferably the anion of p-toluenesulphonic acid.  The invention also comprises a process for the preparation of 3 : 5-di - iodo - 4 - (31 - iodo - 41 - hydroxyphenoxy) - phenylacetic acid (triac) and 3 : 5-di-iodo-4-(31:51 - di - iodo - 41 - hydroxyphenoxy)phenyl-acetic acid (tetrac) by reducing a dinitrodiphenylether of the above general formula to the corresponding diamino compound, tetrazotizing, treating the product with an alkali-metal iodide, and mono- or di-iodinating the compound so obtained, followed or preceded by conversion of R2 (when not hydroxyl) to a hydroxy group and R3 to an acetic acid side chain.  In examples ethyl 3 : 5-dinitro-4-(41-methoxy-phenoxy) phenylacetate (prepared by reacting ethyl 4-hydroxy-3 : 5-dinitrophenyl-acetate with p-toluenesulphonyl chloride and p-methoxyphenol in pyridine without isolating the intermediate quaternary salt) is hydrogenated in ethanol over a palladium calcium carbonate catalyst to the corresponding diamino compound (characterized as its diacetyl derivative) which is tetrazotized and treated with a mixture of sodium iodide, iodine and urea.  The resulting ethyl 3 : 5-di-iodo-4-(41-methoxyphenoxy)-phenylacetate, with phosphorus and hydiodic acid in acetic acid, yields 3 : 5-di-iodo-4-(41-hydroxyphenoxy)phenylacetic acid which is converted into triac or tetrac by mono- or diiodination respectively, with iodine in methanolic ammonia.

Abstract: 847,145. Making electrical components; force fits; soldering. COLE Ltd., E. K., and SMITH, L. A. J. Dec. 2, 1958 [Dec. 4, 1957], No. 37715/57. Classes 83 (2) and 83 (4). [Also in Groups VIII and XXV] Terminal stakes are secured in a rigid synthetic plastic supporting member of insulating material by pushing the stakes through the supporting member so piercing holes in which the stakes are a force fit. The stakes K, Fig. 1, are positioned in holes D in a lower die plate B resiliently supported on a base H carrying rods E which enter the lower ends of the holes D. A printed circuit board A with circuits on the lower face is located on the die B by pins engaging the sides of or apertures in the board A. The upper tool has a die J1 axially above each hole D and a spring-loaded stripper C. On actuation of the press ram to which the upper tool is attached, the board A is forced down on to the stakes K which punch holes in the board and remain secured in these holes. The punched-out portions of the board A are pushed by the stakes K into tapered apertures in the dies J1 and accumulations are ultimately deflected by members L. The apertures in the dies J1 may be smaller than the stakes to upset the ends of the stakes. The stakes K which may be subsequently dip-soldered may be square-sectioned hard-drawn brass wire, silver-plated if desired, or tin-plated steel wire. A modified apparatus, Fig. 3, drives stakes into a tubular synthetic plastic support to form a coil former, Fig. 5. The tube is supported on a pin T and held by a pair of clamping jaws V1, V2 closed by a cam U. The stakes are fed through holes W3 in a fixed plate Q into holes W2 in a slide X which is traversed to bring the stakes over grooves in the ends of the jaws V1, V2. Rods Y attached to a ram are moved downwaids through apertures in the plate Q to engage and drive the stakes through the tube. All the movements are performed by compressed-air cylinders two of which S2, S3 are shown.
