Abstract: 1,158,892. Transformers. YORKSHIRE ELECTRICITY BOARD. 7 Feb., 1967 [30 March, 1966],No. 14005/66. Heading HIT. The fuses 4 and output connections 5 associated with a transformer 1 are mounted on the outside of the transformer tank 2 on a fuseboard combined with the tank, while the bus-bars 8 are mounted on the inside of the tank. The bus-bar connections pass through the wall of the tank via bushings 7 to link with the fuses which may be under a waterproof cover 12 with access doors. Distribution cables 9 pass through cable glands supported by bracket 11. The fuse board includes a row of isolating switches 3 and neutral links 5. In an alternative arrangement (Fig. 3, not shown) the fuses are mounted in a composite plate (13) separate from the tank wall. In this case similar composite plates are used for mounting the neutral links and isolating switches.

Title: Improvements in anti-leprotic drugs
IPC: A61K36/185
Filed: 1931-05-13
Abstract: The fatty acids, mainly chaulmoogric and hydnocarpic acids, obtained by saponification of the oils of flacourtiaceous seeds are purified by crystallization from alcohol and esterified with aliphatic, hydroaromatic or aromaticaliphatic alcohols to form the corresponding esters.  Reduction of these esters gives the corresponding mixed alcohols, which may then be treated with acylating agents to produce their acyl esters.  Flacourtiaceous plants mentioned are Taraktogenos kurzii, Hydnocarpus wightiana, Hydnocarpus anthelmintica, Carpotroche brasiliensis and Caloncoba echinata.  The products are useful therapeutically.  According to the examples, (1) the total fatty acids derived from the said oils are dissolved in hot alcohol and the crystalline acids which separate out on cooling are filtered off, washed with alcohol and dried; the mixed acids are then converted into their ethyl, cyclohexanyl, benzyl, thymyl, methyl and cinnamyl esters; (2) the ethyl esters of the mixed crystalline acids are reduced with sodium and alcohol; (3) the mixed alcohols prepared according to (2) are heated with benzoyl and cinnamoyl chlorides to give the corresponding esters.  Specifications 1984/09 and 311,236, [both in Class 2 (iii), Dyes &c.], are referred to.

Title: Improvements in or relating to isopropylamino-methyl-3.4-dihydroxyphenyl carbinol
Filed: 1953-05-20
Abstract: The invention comprises (1) the resolution of 1 - (3 : 4 - dihydroxyphenyl) - 2 - (isopropylamino)-ethanol by means of its salt with D-tartaric acid formed in the presence of an aliphatic alcohol, and liberation of the optically active free base from the salt, and (2) the active L-form of the base and its acid salt with D-tartaric acid.  The aliphatic alcohol used as solvent preferably has 1-5 carbon atoms, e.g. anhydrous or aqueous methanol or ethanol.  In the examples, (1) the racemic base is added to methanolic D-tartaric acid when the acid salt of the D-base crystallizes out, the free D-base being obtained by treatment with ammonia; the mother liquid yields with ammonia the free L-base which is converted into a salt by adding aqueous ethanolic D-tartaric acid; (2) the racemic base added to D-tartaric acid in absolute methanol gives the acid salt of the D-base; (3) the racemic base and D-tartaric acid in 90 per cent ethanol produce the acid salt of the L-base.

Abstract: 241,251. Fiepmeyer & Co. Kommanditges, and Gella, N. June 12, 1924. Locating conductors.-Subterranean portions of different conductivity are located by sending an alternating current into the ground and determining at various points the strength and direction in a vertical and horizontal plane of the resulting magnetic field. The receiver, Fig. 1, consists of a coil wound on a ring 1, which is mounted on a stand 2 so as to be adjustable about a vertical and an horizontal axis, either of which can be clamped. The ring 1 is provided with a compass 9 to determine its horizontal direction and a clinometer 8 to determine its inclination to the vertical. The coil is connected through an amplifier 3 to a telephone 5 and a vibration galvanometer 6. The transmitter 17, Fig. 4, is adapted to be connected to either of two pairs of rods 18, 18<1> or 19, 19<1> driven into the ground. The ground to be investigated is divided into squares, the transmitter being in the centre with the pairs of electrodes 18, 18<1> and 19, 19<1> at right-angles. The receiving-coil is placed in turn at each intersection and is rotated with its plane vertical until the minimum sound is obtained in the telephone 5, thus determining the direction of the magnetic field in an horizontal plane. The coil is then rotated through a right-angle, about the vertical axis, and is turned about its horizontal axis until the maximum reception is obtained, determining the inclination of the magnetic field to the horizontal. The strength of the field is determined from the reading of the galvanometer 6. These observations are repeated with each pair of electrodes 18, 18<1> and 19, 19<1> in operation.

Abstract: 720,094. Automatic control circuits. P.A.M., Ltd. June 19, 1952 [June 21, 1951], No. 14750/51. Class 38 (4). [Also in Group XL (c)] A thermionic-valve relay circuit for use with temperature-controlling apparatus as described in Specifications 631,595,631,808, [Group XL(c)], and 710,417, [Group XXXVII], comprises a pair of control contacts 1 which when closed cause the contacts of a relay 3 to open. A potential divider 6 applies a portion of the heater voltage desired from mains transformer T to the grid of valve V1 so long as contacts 1 are open and the resultant amplified voltage is applied to the control grid of valve V2 in opposition to a voltage applied thereto from the transformer T. The potential divider 6 is so adjusted that no resultant alternating voltage occurs at the grid of V2 so that current flows through the relay coil 7 and the contacts of the relay 3 close. When, however, contacts 1 are closed, the control grid of valve V1 is earthed by connection to the sheath of the twin-core metal-sheathed cable 8 so that an alternating voltage is applied to the grid of the valve V2 in antiphase with that which is applied to its anode whereby no current flows through the valve V2 and the relay contacts remain open. It can be seen that this arrangement fails " safe," i.e. should the main supply fail or should any of the leads in the cable 8 break or become earthed the contacts 3 will open. Further, the component resistances and condensers may be contained in a single plug-in element as described in Specification 631,808 which if removed from its socket will cause contacts 3 to open. Unidirectional anode voltage for the valve V1 is derived by means of the rectifier 2 and smoothing condenser C1.

Abstract: Silver is deposited within the pores of a porous carbon or graphite body for use as an electrical contact element by impregnating the body with molten silver nitrate, e.g. at a temperature of 212-220 DEG C., and decomposing the silver nitrate by heating the impregnated body in the presence of a gaseous reducing agent, e.g. hydrogen or gaseous formaldehyde, at a temperature below the melting-point of silver nitrate. Impregnation may be effected by floating the body in a bath of molten silver nitrate.  Impregnation is preferably continued until the body is substantially completely saturated.  The porous carbon or graphite body treated may have been incompletely impregnated with polytetrafluorethylene or the mono-, chloro-, bromo-, or iodo-derivative thereof.  In the example, a block of carbon was floated on molten silver nitrate at a temperature of 220 DEG  C. for a period of 90 mins., and then heated in a sealed container in an atmosphere of hydrogen, at a temperature of 190-210 DEG  C. for a period of 1 hour, whereafter the temperature was slowly raised to 300 DEG  C. to produce a product containing 15 per cent of silver.
