Title: Improvements relating to earth leakage protective systems
Inventor: BALDWIN HAROLD TOWNLEY
IPC: H02H3/347
Filed: 1962-02-23
Abstract: 980,415. Protective arrangements. BALDWIN & FRANCIS Ltd. May 20, 1963 [Feb. 23, 1962], No. 7188/62. Heading H2K. [Also in Division H3] An earth-leakage protective system for a polyphase apparatus M comprises a corebalance transformer CBT having an auxiliary primary winding 11 connected to an A.C. source 13 having a frequency which is relatively high with respect to the mains frequency, the secondary winding 12 of the transformer CBT controlling a transistor T which controls the current in the primary winding of an auxiliary transformer 21 having a secondary winding 22 connected to a relay R controlling a main contactor 4, 5. In the absence of an earth fault, the coupling between the windings 11, 12 provides a high frequency control current to the transistor T which provides a high frequency output. This output is amplified at 20, transformed at 21, rectified at 23 and energizes the relay R so that the contactor energizing circuit is closed by the contacts 6 of the relay R. When an earth fault occurs, a current of main frequency is induced in the secondary winding 12 of the transformer CBT and this current causes the transistor to be alternatively cut-off and overdriven so suppressing the high frequency component from the output of the transistor T. The auxiliary transformer 21 presents a much lower impedance to the mains frequency current and its output voltage comes insufficient to maintain the relay R fully energized so that contacts 6 open to open the contactor. The Provisional Specification refers to the provision of lock-out protection when the contactor is open, by injecting a small A.C. current through the fault path, the injection circuit including a further auxiliary winding on the core-balance transformer.

The reaction annulus 2 of an epicyclic sun - planets - annulus gear train is located with respect to an outer fixed casing 1 by two or more links 3 which are substantially tangential to a circle concentric with the pitch circle of the annulus and are resiliently connected to ears on the annulus and casing through rubber-bushed pins 7 so that the axis of the annulus has limited freedom for radial and tilting movements to centre the annulus on the planets and to maintain uniform pressure over the face width of the teeth, while a high resistance to rotation of the annulus is maintained. Each rubber bush, Fig. 2 (not shown), is mounted between two metal sleeves to which it may be bonded, and if natural rubber is employed, oil-resistant synthetic rubber seals may be provided at each end of the bush. In a modification of the four-link arrangement shown in Fig. 1 one of the casing-ears is dispensed with and two of the four links are turned through 180 degrees so that two links share a common ear on the casing. In a further modification the four links shown in Fig. 1 are duplicated so that each of four ears on the annulus has two links disposed in opposite tangential directions and each of four ears on the casing receives two substantially perpendicular links. According to Fig. 5, three ears are provided on both the annulus and the casing and are coupled by two end-connected links 18 and a single link 17 having a resilient connection at its mid-point. In a modification of this arrangement the annulus is supported by only two single links whose mid-points are resiliently connected to diametrically opposite ears on the annulus. Specifications 581,464 and 732,436, -[both in Group XXXII], are referred to.

Patent GB-846847-A (GB)
Title: An improved method of producing conjugated diolefines
IPC: C07C11/12
Filed: 1959-03-03
Abstract: Conjugated diolefines are prepared from monoolefines having at least four carbon atoms by reaction, in the liquid phase, with oxygen or an oxygen-containing gas at less than 150 DEG C to form a hydroperoxide, converting the hydroperoxide into the corresponding alcohol at less than 150 DEG C. and dehydrating the alcohol catalytically at 100-375 DEG C.  If the olefine is such as would vaporise under the reaction conditions in the first stage, increased pressure may be used or an inert solvent added, e.g., benzene, to which may be added nitrobenzene, or chlorobenzenes. Some hydroperoxide is preferably present in the feed as an initiator and the effluent preferably contains 2-20% hydroperoxides based on olefines, the solution being concentrated if desired.  Where atmospheric pressure is used the temperature preferably 50-125 DEG C., should be 15 DEG C. below the boiling point of the olefine.  Conversion to the alcohol may be effected at 30-80 DEG C. using a reducing agent, e.g., potassium or sodium iodide, potassium or sodium hydrosulphide, ferrous thiocyanate and titanium sulphate, stannous and titanium chlorides, arsenites and lower valence state salts of lead, iron, copper, mercury, manganese or cobalt, or at 0-40 DEG C. with a catalyst such as powdered cadmium, lead, tin, bismuth, silver or copper, salts of cobalt, manganese, lead, copper, iron or mercury, hydroxides of sodium, potassium, calcium or barium, organic bases such as amines or ethanolamine, or activated carbon, or simply heating at 60-150 DEG C. Dehydration may be effected in the vapour phase at 200-375 DEG C. over alumina, thoria, chromia, tungsten oxide, clays, kaolin, alum or sodium phosphate on alumina at atmospheric pressure or in the liquid phase using mineral acids such as phosphoric or sulphuric, hydracids such as hydrochloric, hydrobromic or hydroiodic, salts such as zinc chloride, potassium and sodium sulphates or phosphates, iodine, alumina or clays.  The examples describe the following conversions:- (1) heptene-3 to heptadiene-1,3 and -2,4; (2) dodecene-2 to dodecadiene-2,4 and -3,5; (3) 2-methylpentene-2 to 2-methylpentadiene -1,3 and-2,4; (4) 4-methylheptene-3 to 4-methyl-heptadiene-2,4 and -3,5; (5) 3-methylbutene-1 to isoprene; (6) cyclohexene to cyclohexadiene -1,3 ; and (7) 1-methylcyclohexene-2 to methyl-cyclohexadienes.

Title: Device for the electro-magnetic release of camera-shutter and ignition of flash light lamp
IPC: G03B15/04
Filed: 1946-03-11
Abstract: 613,868. Photographic cameras combined with flashlights. OSCHWALD & CO., A. March 11, 1946, No. 7570. Convention date, March 26, 1945. [Class 98 (i)] An electromagnetically-operated flashlight and camera shutter synchronizer of the kind in which the shutter-release actuating member is held set against the action of a driving spring and is released by energizing an electromagnet which attracts the holding means, comprises (1) an actuating member which passes through the core of the magnet and its associated armature and carries an annular protuberance in which the driving spring is seated, and (2) a locking pawl disposed laterally of the actuating member engaging a shoulder on the exterior of the protuberant spring seating and a flange on the armature, so that, upon energizing the magnet, the attracted armature releases the foot of the pawl which rotates to allow the spring seating to be driven downwards and thus cause the actuating member to operate the shutter release, energization of the magnet causing firing of the flash lamp at the appropriate instant. As shown, the magnet 3 is carried in the lower part of the housing of the device, and one end of the driving spring abuts against the top of the upper part 2, the parts 1, 2 being screwed on to an annulus 11 on which the locking pawl 14 is pivoted at 13 in a slot 11s, the armature 12 being slidably disposed in the bore of the annulus, while the shutter-release actuating member comprises a pin 7 having a thickened screw-threaded stem 7a adjustable in a member 6, which carries the seating 9 for the other end of the spring 10. When the device is used with between-lens shutters the lamp L is shunted across the magnet coil so that on closing the switch S the lamp is fired and simultaneously the magnet is energized so that the pin 7 strikes the shutter pin C. In an alternative embodiment intended for use with focal plane shutters or shutters of reflex cameras, whose release is delayed by movement of the pivoting mirror, which shutters have greater inertia than between-lens shutters, the flash lamp circuit is closed by a disc on the end of the member 6 which engages a contact adjustable axially of the device, the disc and the cylinder in which it moves acting as a dash-pot to control the interval between shutter-release actuation and firing of the flash lamp. Specification 508,074 is referred to.
