Inventor: UTO YOSHIMITSU
IPC: B23K9/00
Filed: 1967-02-14
Abstract: 1,182,142. Pressure vessel. MITSUBISHI JUKOGYO K.K. 14 Feb., 1967, No. 7119/67. Heading B1X. [Also in Division B3] In a laminated pressure vessel in which each lamination consists of one or more plates joined by seam welds, the inner or outer lamination is formed of hydrogen resistant steel and the weld(s) of the adjacent lamination is maintained out of contact with the hydrogen resistant steel by interposition of a backing strip. The weld 3 is backed by a steel strip 20 contacting the inner hydrogen resistant lamination 1. The other laminations are not hydrogen resistant. A gas passage 16 extends through the wall of the vessel to the inner lamination 1. The strip 20 and the passage 16 minimise hydrogen contamination of the laminations 12 ... 16.

Title: [poly]en[poly]ynic carboxylic acids and a process for the manufacture and conversion thereof
Inventor: OSBOND JOHN MERVYN
IPC: C07D303/38
Filed: 1960-03-01
Abstract: The invention comprises (poly)en(poly)ynic acids of the general formula <FORM:0909354/IV (b)/1> wherein x and y each represent a whole number from 1 to 3, z represents a whole number of from 1 to 9, and wherein the olefinic bonds are in cis configuration, specifically octadecaen-(12;cis)-yn-(9)-oic, nonadecaen-(13; cis)-yn-(10)-oic, and octadecadien-(9,12; cis)-yn-(6)-oic acids and a process for the preparation thereof by condensing an all-cis halide, CH3(CH2)4(CH=CH-CH2)xX, in which X is a chlorine or bromine atom, with a diGrignard derivative of an acid <FORM:0909354/IV (b)/2> in the presence of cuprous ions or of copper metal, and decomposing the metal complex formed.  The process may be carried out in an inert solvent such as tetrahydrofuran and cuprous cyanide is preferred as catalyst.  The metal complex may be hydrolysed by the use of ice and sulphuric acid and an ammonia extract, acidified to give the desired acids.  The acids may in addition, be partially reduced to the corresponding polyenic acids by catalytic hydrogenation, for example in the presence of a lead-inhibited palladium catalyst in the presence of quinoline, or alternatively epoxidised at the olefinic bonds by for example peracetic, perbenzoic, perphthalic and performic acids, followed by partial hydrogenation using a lead-inhibited palladium catalyst to give the corresponding cis[poly]epoxy[poly]enic acids.  Examples describe the preparation of the above specified acids and their hydrogenation to octadecadien-(9,12; cis)oic acid and epoxidation to 12,13-cisepoxy-octadecayn-(9)-oic acid followed by reduction to 12,13 - cisepoxy - octadecaen - (9; cis)oic acid, (vernolic acid); hydrogenation to p  nonadecadien-(10,13; cis)-oic acid and epoxidation to 13,14-cisepoxy-nonadecayn-(10)-oic acid followed by reduction to 13,14-cisepoxy-nonadecaen-(10; cis)-oic acid; and partial reduction to gammalinolenic acid respectively. Specification 859,897 is referred to.

Abstract: 652,052. Automatic temperature control systems. BRITISH THOMSON-HOUSTON CO., Ltd. March 16, 1948, No. 7877. Convention date, March 20, 1947. [Class 38 (iv)] A temperature control system for an electric furnace 1 comprises two grid controlled thyratrons 7, 8 supplying the saturating winding of a saturable core reactor 5 connected in series with an electric heater 2, and a bridge circuit including a temperature variable resistance 9 for varying the bias applied to the thyratrons in order to control the temperature of the furnace 1. The grids of the thyratrons are supplied with an alternating voltage from a transformer 18 which lags substantially 120 degrees behind the plate voltage and is of a magnitude equal to the critical starting voltage of the thyratrons. The output of the bridge circuit is also applied to the grids of the thyratrons via transformers 14, 15 and is arranged when the furnace is at the predetermined temperature to be 180 degrees out of phase with the plate voltage and of a magnitude such that the thyratrons pass current over one half of the plate voltage wave. The combined grid voltage of the thyratrons are such that they pass current for a time depending on the phase and magnitude of the output voltage from the bridge circuit, and then on the temperature of the heater. The thyratrons control the current applied to the D.C. winding 6 after rectification at 33 of the saturable reactor 5 so as to vary the imput to the heater in a sense to maintain the furnace at the predetermined temperatures. If desired, one thyratron only may be employed.
