Patent GB-1123263-A (GB)
Title: Preparation of ª-(1-acylated-3-indolyl) aliphatic acids
IPC: C07D209/18
Filed: 1966-07-11
Abstract: Esters of a -(1-acylated-3-indolyl) aliphatic acids are hydrolysed to the free acids, the hydrolysis being any acidolysis if C1- 5 primary or secondary alkyl esters are used and a hydrogen halide acidolysis if C4- 5 tert.-alkyl or phthalimidomethyl esters are used.  The esters may contain substituents in the indole nucleus or the 3-side chain.  A preferred method of acidolysis involves the use of a sulphonic acid and an alkanoic acid.  Phthalimidomethyl (2 - methyl - 5 - methoxy - 3 -indolyl)-acetate is prepared by reacting N-chloromethylphthalimide with levulinic acid to give phthalimidomethyl levulinate, and reacting this with p-methoxyphenylhydrazine hydro-chloride. Other similar phthalimidomethyl esters with different substituents in the 2- and 5-positions, with substituents and the 4- and 6-positions of the indole nucleus and with alkyl substituents on the carbon atom a  to the ester group are prepared similarly.  Phthalimidomethyl (2-methyl-5-nitro-3-indolyl)-acetate is prepared by reacting levulinic acid with p-nitrophenylhydrazine hydrochloride to give, after cyclization, 2-methyl-5-nitro-3-indolyl acetic acid, and esterifying this.  Other phthalimidomethyl esters are prepared similarly, as are alkyl esters from the free indolylacetic acid and alkanols; an example is ethyl (2-methyl-5-methoxy-3-indolyl)-acetate. All the foregoing esters are converted to their N-acyl derivatives by reaction with acyl chlorides e.g. p-chlorobenzoyl chloride.

Title: Process for the hydrogenation of unsaturated hydrocarbons
IPC: C07C5/02
Filed: 1938-10-27
Abstract: 520,115. Catalytic hydrogenation. MOND, A. L. (Universal Oil Products Co.). Oct. 27, 1938, No. 31128. Drawings to Specification. [Class 1 (i)] [Also in Group IV] Unsaturated hydrocarbons, in particular dimers obtained by polymerizing butenes, are catalytically hydrogenated in two stages by first treating with a limited quantity of hydrogen so as to effect only a partial saturation, then completely saturating in a second stage into which fresh hydrogen-containing gas is introduced, separating the saturated material from residual hydrogen-containing gas, supplying such an amount of said gas to the first stage as will provide said limited quantity of hydrogen therein, and recirculating a sufficient quantity to the second stage to maintain a substantial excess over that required for complete saturation of the partially saturated material and to secure a total supply of fresh and recycled gas to the second stage which is about 1.8-3.5 times as large as the quantity of residual gas supplied from the second to the first stage. Preferably 35-65 per cent. of the residual gas from the second stage is supplied to the first stage. Gas mixtures of fairly high hydrogen content, e.g. hydrogen obtained by cracking hydrocarbons or gas mixtures obtained by the action of steam on methane, may be used as the hydrogenating gas. The preheated mixture of olefines and hydrogen, generally at about 150-315‹C. and 1-35 atmos., is passed downwards through a catalyser comprising multiple parallel tubes containing granular catalyst and surrounded by circulating cooling medium. The partially hydrogenated product is separated by condensing, mixed with the primary hydrogen supply and recirculated hydrogen from the receiver of the second stage. preheated, and passed through a second catalyser. A somewhat higher pressure is preferably used in this stage than in the first. The completely hydrogenated product is condensed, and an amount of gas recirculated so that there is a considerable excess over that necessary for saturation. The remainder of the gas is supplied to the first stage. It is desirable to maintain in the second stage a molar ratio of hydrogen to partially hydrogenated hydrocarbons of at least 1.3:1, and often 2:1 or higher. Specification 490,768 is referred to.

Patent GB-1115874-A (GB)
Title: Improvements relating to the production of electrolytic condensers
IPC: C25D11/04
Filed: 1966-07-12
Abstract: In anodizing a metal foil strip, as of roughened aluminium, for subsequent use as electrolytic capacitor electrodes, the strip is moved continuously through an anodizing bath or baths with a fixed applied voltage which effects oxidation (forming) and the anodizing process is then interrupted by reducing the applied voltage to a value less than half the initial voltage for a short period, the voltage thereafter being gradually raised until oxidation starts again, forming being continued until a desired residual current is obtained.  The voltage may be cut off temporarily but preferably it is merely reduced to a suitable value below that at which oxidation restarts, and is then gradually increased either steadily up to the maximum originally applied or steadily to just above the value at which oxidation restarts and then raised directly to the maximum value.  The foil which typically passes between or through the counter-electrodes which are earthed may remain in the bath or be removed from the bath between the two oxidation stages, or two separate baths may be employed.  Devices for ensuring the increasing applied voltage of the second stage may comprise funnel shaped electrodes extending downwardly through the bath surface; electrodes covered with insulation arranged to extend downwardly in V formation through the bath surface and to which voltage pulses are applied, bath liquid being fed downwardly through them; insulating barriers immersed in the bath or extending through the bath surface to restrict access of electrolyzing current to the foil which thereafter passes between immersed parallel electrodes, electrolyte being flowed downwardly between them; or slit orifices for directing electrolyte in counter-flow to the direction of foil movement as it passes to the entry of a pair of electrodes.

Title: Improvements in self-contained rural transformer substations
IPC: H02B7/06
Filed: 1928-11-01
Abstract: 305,525. Condit Electrical Manufacturing Corporation, (Assignees of Burnham, G. A.). Feb. 6, 1928, [Convention date]. Transformers.-A transformer is structurally combined with a circuit breaker and disconnecting switches in order that it may readily be installed on a prepared base 122 and connected to overhead transmission and distribution lines 126, 130 for use as a rural substation. The disconnecting switches 36, 46 for the high tension and low tension windings are mounted on a supporting structure 30 on the cover 12 of the transformer casing 10, and are operated through rocking levers 110, 112 and rods 102, 104. The rods are connected to opposite ends of a lever 100 rocked by a shaft 96 operated by a removable handle adapted to be inserted in a radially-projecting socket 98. The shaft 96 is carried by the cover 80 of a casing 50 forming an extension of the transformer casing 10 and in oil communication therewith. Within the casing 50 are located the contacts 58 of the circuit breaker which are adapted to be closed in opposition to a spring through link-work 66, 68, 74, 76 by rocking a shaft 78 by means of a removable handle 84. The shaft 78 carries an arm that interlocks with an arm 118 on the shaft 96 so that the disconnecting switches can only be operated when the circuit breaker contacts are open. These are normally maintained closed by a latch 86 engaging a projection 88. The latch can be tripped by movement of the armature 92 of an overload coil 90, or by manual operation of a trigger 93 operating through a rod 94. The transformer shown is of the three-phase type, and the circuit breaker is arranged to complete the primary circuit by connecting together the three ends of the primary windings as shown in Fig. 8. The three insulating bushings 54 required for supporting the fixed contacts of the circuit breaker are located under the oil, and by extending the base 52 on which they are mounted downwardly, sludge formed by arcing is prevented from passing into the transformed casing.
