Title: Improvements in electric protective systems
IPC: H02H7/22
Filed: 1934-03-26
Abstract: 433,887. Protective cut-out arrangements. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and GARRARD, C. C., c/o General Electric Co., Witton, Birmingham. March 26, 1934, No. 9427. [Class 38 (v)] An arrangement for giving protection in the event of damage to a cable in a mine or other place subject to explosive atmosphere, of the kind in which an auxiliary lead is incorporated in the cable and adapted to carry control current, has the cable provided with two insulated screens disposed around the conductors and located in the go and return paths for the control current. The screens are associated with control gear for disconnecting the main conductors on the occurrence of a direct electrical connection between the screens. The gate-end switch box 1 is connected to the machine-end box 2 by a threecore trailing cable having an earthing conductor 5 and screens 6, 7 carrying the current for controlling the main switch 13 from the reverser and control switch 10 at the machine end. The screens 6, 7 are interconnected over resistances 11, 37 and contacts 12 which are closed in operative positions of the reverser. One side of a rectifier 33 is connected to screen 7, whereas the other side is connected to 6 over contacts 29 of a relay 30, relay coils 26, 21, and contacts 27 of an overload relay and " stop press-button 36. With contacts 12 closed, insufficient current flows to energize 21, but by operation of 10 the resistance 11 is momentarily shorted, and 21 closes its contacts 19 to energize relay 17 which closes at 15 the circuit of contactor coil 14. If the cable gets damaged so that 6, 7 come in contact and short the resistances 11, 37, coil 26 closes contacts 25 to energize 24, which opens at 22 the circuit of 17, so causing 13 to disconnect the cable from the supply. Leakage from the main conductors causes coil 30 to open the control circuit and closure of test switch 44 simulates this faulty condition. A test switch 43 is provided for effecting a leakage test by connecting the screens and operating relay 26, and a " start " switch 40 and link 41 are provided for closing the main circuit at the gate-end. The relays in the control circuit are arranged to have low inductance, and the short-circuit current of transformer 18 is also small, so that the spark-energy at a point of short-circuit is too low to ignite combustible gas. The Provisional Specification refers also to two pilot conductors in the cable connected in parallel with the respective screens, and to auxiliary plugs and sockets which do not engage until the couplings are locked in position.

The reel bar has a surrounding cardboard sleeve T, while one end of the reel bar R is welded to a flange 11a integral with an extension 11 which receives the tapered end 13a of the spindle A in a bore 11c. A flange 11b has three bores 11e spaced apart 120 degrees which receive pins 14a projecting from a flanged sleeve 14 mounted on the spindle A. A similar arrangement is provided at the opposite end of the reel bar R. The spindle A carries the inner races of spaced apart roller bearings 16 and 17, the outer races of which are housed in a sleeve 18 axially slidable in a liner 19 secured by a pin 20 in a bearing shell B, the pin 20 engaging in a slot in the sleeve 18. The spindle A is extended by a piston rod 15 carrying a doubleaoting piston 22 slidable in a hydraulic cylinder H supplied alternatively with hydraulic fluid under pressure through a connection 23 or open to exhaust through a connection 24 to move the piston to the right or left. Thus, the spindle A may be released from or engage the extension 11 of the reel bar R. The hydraulic system includes a valve, not shown, which maintains the piston 22 in a required position after displacement, such valve being automatically unlocked by application of pressure in the reverse direction to that previously applied. Alternatively or additionally, the sleeve 18 may be locked frictionally to the liner 19 by a bolt 25 engaging slots in the liner 19, and a tapped bore in the sleeve 18. According to the Provisional Specification, one end of the reel bar has a coarse thread engaging a nut holding a collar non- rotatable relative to the reel bar, the collar carrying a longitudinally projecting 'key for engagement in the cardboard sleeve. A similar arrangement, provided with a finer thread, at the opposite end of the reel bar provides means for tightening the sleeve after positioning by the coarse thread.

Title: Manufacture of acids of the trisnorlanostane series and their derivatives
IPC: C07C51/36
Filed: 1952-04-18
Abstract: The invention comprises trisnorlanostanic acids (and esters thereof) nuclearly substituted as in the formula <FORM:0779188/IV(b)/1> where R is a substituted hydroxyl group and R1 is a free or esterified carboxylic group.  These are made by oxidizing "isocholesterol" or an ester or ether thereof directly or in stages with temporary protection of the reactive double bond (e.g. with halogen or hydrogen halide) and at any stage reducing the nuclear double bond with nascent hydrogen.  In the examples, isocholesterol acetate is oxidized with chromic acid to trisnor-acetoxylanostendionic acid and the latter (or its 3-hydroxy hydrolysis product) esterified with diazomethane.  The acetoxyester is reduced with zinc and glacial acelic acid to acetoxy-trisnor-lanostandionic acid methyl ester.  The action of alkali on the latter hydrolyses the acetoxy and carboxylic ester groups, the latter being subsequently re-esterified with diazo-methane.  In a further example, the double bond in the side chain of isocholesterol acetate is saturated with bromine and the 7 : 11-keto groups introduced with chromic acid as before. Treatment of the product with zinc and glacial acetic acid reduces the nuclear double bond and removes the bromine to give a product oxidized by chromic acid to acetoxy - trisnor - lano - standionic acid, esterified with diazomethane to the same product as before.

Abstract: 990,726. Telegraphy. SIEMENS & HALSKE A.G. March 10, 1964 [March 26, 1963], No. 9955/64. Heading H4P. A control unit in a teleprinter link causes both call-charging equipment operation and initiation of the through-connection. Prior to the setting up of the through-connection the dialled code of the called subscriber and the code of the calling subscriber are recorded, and subsequent to it the chargeable time is recorded until the link is cleared. The dialled code of the called subscriber is received over line a and punched in tape at EM. At the end of the dialling, contact u1 reverses and a current flows to switch on the calling teleprinter, whereafter w1 reverses and unit MT requests the code of the calling subscriber. This is recorded at EM, which is then scanned by WS so that the connection required is set up by unit SU. WS now requests the called station to identify itself, the response being recorded at EM and also passed to the calling teleprinter; relay L reverses its contacts l and the through-connection is made. Unit ZIG produces timing pulses which are punched in tape at EM until L releases, which it will not do until the locking circuit, which includes c1, is opened when seizing relay C releases when the line is cleared. While L is energized the record can be scanned by monitor KE. A plurality of these control units will be provided in an exchange, and they are additional to the normal accumulative charge registers. A control unit is called into operation by prefixing the dialled code by a special code.
