IPC: H01B11/14
Filed: 1930-04-11
Abstract: 351,622. Cables. SMITH, W. S., Benchams, Newton Poppleford, Devon, GARNETT, H. J., Lymne, Solefields, Sevenoaks, and DEAN, J. N., Kincraig, Keswick Road, Orpington, both in Kent. April 11, 1930, No. 11583. Drawings to Specification. [Class 36.] A continuously loaded submarine cable having a pressure-equalizing medium comprising a paraffin hydrocarbon such as petroleum jelly, and an outer layer of insulation such as rubber for which the equalizing medium has an affinity, is provided with a layer of insulation intermediate the medium and the outer insulation, the intermediate insulation being such that it does not react with the outer insulation. The intermediate insulation may consist of guttapercha or balata or a mixture of the two, preferably treated so as to remove the whole or part of the resins and dirt. Preferably the intermediate insulation consists of a mixture of dirt- and resin-free guttapercha and petroleum jelly as described in Specification 346,382, [Group V]. The pressure equalizing medium may be surrounded with a series of layers of insulation, which are saturated with the pressure equalizing medium to an extent which decreases progressively with the distance of each successive layer from the conductor. It is stated that, by this construction, a smooth potential gradient is obtained. Specifications 307,087 and 326,481, [both in Class 36, Electricity, Conducting &c.], are referred to.

Abstract: 566,966. Internal-combustion power plant. AKTIEBOLAGET GOTAVERKEN, and OLSSON, J. July 16, 1943, No. 11616. [Class 7 (ii)] [Also in Group XXXIII] A number of internal-combustion engines 1, or other prime movers, which are adapted to drive a common shaft 4, are controlled as to starting, stopping, reversing, &c. by rotation one way or the other of a common operating member 9 connected through gearing 12, 13, 14, 15 and clutches 16 to the control shafts 17, Fig. 2, of each engine. The control shaft of any engine may be disengaged from the member g by releasing its clutch 16 by moving a handle 30 from the dotted to the full line position, thereby causing the disengagement of clutch members 33, 34 and this action may also open a switch 43, causing the opening of a switch 37 controlling an electric slip coupling 2 so that the engine in question is now completely detached from the shaft 4 and may be operated and reversed &c. by movement of the handle 30, which is pivoted to the shaft 17, in a direction to turn the shaft one way or the other. In the complete arrangement shown, when the plant is to be started, the control handles 30 of those engines that are to be used are moved into the dotted position. When an order is received by the engine-room telegraph 8, a wheel 50 is moved in a corresponding manner and serves to complete circuits through all the switches 43 of the selected engines to cause the closure of their switches 37 and the consequent energization of their clutches 2. The wheel 9 is then moved in accordance with the order, causing all the selected motors to move in forward or reverse direction. Specification 547,543 is referred to.

IPC: C07J5/00
Filed: 1955-04-22
Abstract: D 1 : 4-3-Keto steroids containing no reactive carbonyl group other than the 3-keto group are separated from their mixtures with other 3 - keto -, D 1 - 3 - keto -, D 4 - 3 - keto - and/or D 4 : 6-3-keto-steroids by treatment of the mixtures with Girard reagent T or P in a solvent medium to form water-soluble Girard derivatives with the other steroids and then isolating the unattacked D 1 : 4-3-keto compounds.  The process is especially applicable for the production of compounds of the formula: <FORM:0788307/IV (b)/1> (R1 is a ketonic oxygen atom or a hydroxyl group, R2 is a hydrogen or halogen atom, R3 is an acyl group, and R4 is hydrogen or an acyl group).  The solvent may be water-miscible, e.g. ethanol-acetic acid, or water-immiscible, and on completion of the reaction the mixture is preferably treated with dilute aqueous alkali and the D 1 : 4-3-keto steroid isolated by extraction with a water-immiscible solvent, e.g. methylene chloride or an ester such as ethyl acetate.  The mixture of 3-keto steroids may result from dehydrobromination of the corresponding 2,4-dibromo-3-keto-5a -steroids.  In examples (1), (2), (4), (6) and (7) : mixtures of 3-keto steroids (obtained by bromination and dehydrobromination of cortisone acetate) are treated with Girard P or T in acetic acidethanol, the product poured into aqueous sodium bicarbonate and 1,2-dehydrocortisone acetate extracted with ethyl acetate or methylene chloride; (3) and (8) 1,2-dehydrocortisone 17,21-diacetate; and (5) D 1 : 4-cholestadien-3-one are similarly obtained from mixtures of 3-ketosteroids.

Abstract: 1,184,191. Mixing liquids. HILTI A.G. 14 March, 1967 [5 April, 1966], No. 11878/67. Heading B1C. [Also in Divisions B3, E2, F1 and F2] In a method of adhesively attaching a fastening element to a foundation by an adhesive comprising two or more components, the element has a recess for the adhesive into which the components are injected concurrently with mixing them in a mixirig zone in the fastening element. Fig. 4a shows a fastening element 45 having a screw thread 46, an adhesive recess 47 and inlet apertures 49 for the adhesive components; ribs 48 in the recess effect mixing when the element is rotated. In a modification, Fig. 1 (not shown) the element incorporates a labyrinthine mixing channel (22) between the inlets and the recess. In a further modification, Fig. 2 (not shown) the labyrinth (33) is incorporated in a part (28) which can be broken off when adhesion is complete, and the adhesive recess (36) has ribs (37) to increase the anchorage area. A cable clamp, Fig. 3a, has such a break-off mixing chamber 38 with a mixing screw 41 which is rotated by the tool which injects the adhesive components. An anchor fastener, Fig. 5, comprises a threaded dowel 51 located in a bore 52 in a foundation, the adhesive constituents being injected with the bore 52 by way of an axial bore 53 in the dowel containing a helical insert 54. The dowel has anchorage grooves 58. Another fastening element (67, Fig. 6a not shown) to be secured to a conical depression in a concrete foundation (66) is of complementary shape thereto and has a screwthreaded socket (70), and an injection channel (78) connecting with a recess (69) for adhesive. An injection tool for the adhesive components has pistons (89), Fig. 8 (not shown) which are simultaneously operated by a knob (91) and yoke (88). The components may be contained in cartridges (82, Fig. 7 not shown) made e.g. of polyethylene and having walls integral with bases recessed to accommodate the pistons (89). The tool has conveying discharge channels (95) obturated by spring- loaded plungers (97). These are retracted by feelers (100) when the tool is applied to the fastening or mixing chamber. The cartridges are proportioned to supply the components in the required ratio. In a modified tool, Fig. 9 (not shown) the entire tool is rotated within a grip (105) to drive a mixing element, by insertion of the push shaft (101) in the chuck of a portable drill, not depicted.

Abstract: 238,019. Bingham, G. C., and Bingham, A. G. S. May 14, 1924. Drinking-appliances for animals.-The watersupply to a drinking-trough for cattle &c. is controlled by the weight of the trough and its contents the trough being raised by a spring or counterweight when empty allowing ing water to enter, and descending when full, so cutting off the supply. The trough e, Fig. 1, pivoted at d<1> makes contact through an adjusting screw e<1> with a pivoted member f that carries an adjusting screw f<1> resting upon a spring g. The member f is pressed back when the trough is full and closes the valve in a casing a. The intermediate member f may be dispensed with or may take the form of an angle bracket f, Fig. 3, in which the trough or bowl e is pivoted so that it may be tilted for emptying. A double trough may be employed, the outer trough o, Fig. 7, having a central outlet closed by a valve l on the inner trough p. When the inner trough p is full the pressure of the springs g is overcome and the valve l is closed, but the valve c remains open since the outer trough o is supported by springs h. Water therefore overflows, flushing the inner trough, until the weight of water in the outer trough depresses it allowing the valve c to close. When the inner trough is partially emptied it rises opening the valve l. Pockets m containing disinfectant may be provided.
