Title: Improvements in joints for high tension electric cables
IPC: H02G15/10
Filed: 1933-06-01
Abstract: 416,695. Cable joints; cable end constructions. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., BRAZIER, L. G., and STIENON, M., Hamilton House, Victoria Embankment, London, and ALLCOCK, H. J., c/o Callender's Cable & Construction Co., Belvedere, Kent. June 1, 1933, No. 15847. [Classes 36 and 38 (i).] The ends of high-tension cables are formed or fitted with a series of conducting layers G embedded in insulation F, the inner layers lying nearer to the end of the cable core B, so that as the insulation is tapered off in making a joint a layer of conducting material is exposed at each step and is secured by a wrapping of tape R. The joint C, which may be of the spring plug type, and a substantial portion of the tapered ends of the cables are surrounded by a sleeve N of rigid dielectric material secured between rings O in a conducting tube M connected with the cable sheaths H. If the layers G are formed in the cable end during manufacture the diameter of the cable is increased at that part. The joint C is positioned by a disc D held between rings E of tape and the tube M has an end piece L connected to the tube M and sheath H by plumbed joints. According to the Provisional Specification, the sleeve N can be tapered to fit closely to the pencilled ends of the cables, and the tube M can then be of about the same diameter as the cable sheaths.

Title: Process for the manufacture of technically valuable compounds from oxidation products of drying oils
IPC: C11C3/00
Filed: 1932-06-06
Abstract: Sulphite compounds of oxidized drying oils are made by treating blown oils or oxyns with sulphurous acids or its salts.  The oxyns prepared from linseed, perilla, soya bean or tung oil by the process described in Specification 238,200, [Class 91, Oils &c.], are suspended in water and agitated with sulphurous acid.  The resulting foaming mass is heated to remove excess sulphurous acid, whereupon the sulphite compound is precipitated and is rendered water-soluble by treating with an alkali base or ammonia. Water-soluble compounds may be made directly by replacing sulphurous acid with an aqueous solution of sodium bisulphite. The resulting solution is freed from salts by dialysis.  The reaction may be effected at 100 DEG  C. under pressure of 10 to 15 atmospheres, and in the presense of solvents such as toluene, xylene, ethyl or butyl acetate or methylene chloride. Aqueous solutions of such compounds may be used in the manufacture of adhesives or paints, and on evaporation yield films which may be hardened and rendered insoluble by heating to 100 DEG  C. or by treating with oxygen or hydrogen peroxide.  The water soluble compounds may be treated with alkaline earth or heavy metal salts, e.g. barium, calcium or ferric chloride or lead acetate to form resinous substances which may be used as varnish ingredients.ALSO:Sulphite compounds of oxidized drying-oils are made by treating brown oils or oxyns with sulphurous acids or its salts.

Title: Improvements in Thermally Controlled Releasing Apparatus for Fire Doors and the like.
Inventor: WOOSNAM ARTHUR
IPC: E05B65/10
Filed: 1916-11-22
Abstract: 107,522. Woosnam, A., (Lowe, E. A.). Nov. 22, 1916. Fires, preventing and minimizing in connexion w i t h doors, windows, ventilators, and the like. - Fireproof doors, windows, or shutters are automatically closed, or ventilators automatically opened, either when the temperature exceeds a certain amount or when the rise of temperature exceeds a certain rate. The door 41, Fig. 8, is arranged to slide down the rail 42 by gravity, but normally is prevented from doing so by means of a weight 44 attached to a pulley 47 suspended on the cord 45 attached at one end to the door by means of a fusible link 58 and at the other end to a detent arrangement 1<1> released by apparatus actuated by a thermal device, which operates when the rate of rise of temperature becomes excessive. One or more air chambers 22, Fig. 3, have connected therewith a restricted vent 23, containing air-filtering material so arranged that normal change of temperature does not appreciably affect the pressure while an abnormal rise of temperature causes a rise of pressure. The air chamber 22 is connected by a pipe 21 to a chamber containing a diaphragm 20, Fig. 2, movement of which releases a train of detents, by which a forked arm 2, Fig. 1, supporting the end of the cord 45 is allowed to turn and thus close the door. The arm 2 carries on its shaft a detent arm 3, Fig. 7, which, in the normal position, engages under a shoulder on the spring- actuated arm 6, the upper end of which engages a stop 7 mounted on the pivot of a rock-lever 9 provided with a latch 12 interlocking with the spring latch 13. Attached to the latch 13 is a lever 15 engaged by a hook 18 of a spring-actuated catch 17, which is held by the lever 19. On a rapid rise of temperature, the diaphragm 20 buckles, moving the lever 19 and thus unlocking the arm 17 and releasing a catch 18 from the lever 15. The shaft 13 then rotates under the action of the spring 18 and releases the lever 9, which, under the action of a weight 10, turns and releases the arms 3, 6, thus releasing the door. The apparatus is re-set by means of a handle 5', Fig. 1, operating an arm 30, Fig. 7, to which is pivoted a slotted arm 25, in which slides a pin attached to the extension 26 of the arm 9. The arm 6 is re-set by means of a pin 31 with which the arm 30 engages and the lever 17 by the hook 27 on the arm 30. The lever 3 automatically falls into its normal position by means of the counterweight 2<1>, Fig. 1. Instead of the fusible link being mounted in the cord 45, the lever 2 may be made in two parts pivoted together and united by a fusible link.

Title: Improvements in or relating to receivers for receiving modulated carrier waves
IPC: H04B1/12
Filed: 1942-11-25
Abstract: 562,553. Wireless receiving circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Nov. 25, 1942, No. 16754. Convention date, Nov. 25, 1941. [Class 40 (v)] A receiver for receiving a modulated carrier wave in the presence of an interfering wave which sets up heterodyne interference comprises means for detecting the amplitude and frequency modulation components of the combined modulated and interfering waves and for combining the detected components so as to cause the heterodyne components therein substantially to cancel one another to leave the modulated wave free from heterodyne interference. As shown in Fig. 1, as applied to an amplitude modulation receiver, the intermediate frequency is fed to circuits 1<1>, 1<11> tuned to frequencies lying on either side of the intermediate frequency. Circuit 1<1> is connected in series with resistances 12, 13 between the anode and cathode of a diode 2, and circuit 1<11> is similarly connected with resistances 15, 16 and diode 3, byepass condensers 14, 17 being provided. The cathode of 3 is earthed. The frequency modulation component of the heterodyne interference is fed via condenser 5<1> and potentiometer 5 to the grid 9 of a double triode 6, while grid 8 receives from potentiometer 4 and condenser 4<1> an amplitude modulation voltage which includes the desired signal and the interference. The outputs from the two triode sections are combined in the primary of output transformer 7 either in phase addition or opposition depending on the position of switch A, according as the interference is on one side or the other of the desired carrier frequency. By this means the F.M. and A.M. components of the heterodyne interference cancel one another leaving the pure signal. The relative amplitudes of the two components are governed by the settings of potentiometers 4 and 5. In the modification shown in Fig. 2, load resistor 30 of diode 2 is connected to the junction of load resistors 31, 32 of diode 3 so that only half the output from diode 3 is applied to the grid of amplifier 34 via tapping point 2<1> and resistance 33. Thus with tapping point 2<1> in the middle of 30, the circuit is a balanced F.M. detector. By moving the tapping point to one side or another, the A.M. component of the interference appears in correct sign to cancel the F.M. component and leave the signal for transmission to the output transformer 35. The arrangement may also be used to remove heterodyne interference in an F.M. receiver. In this case the limiter is dispensed with, so as to pass the A.M. component of the interference.
