Abstract: 748,275. Rectifying. ENGLISH ELECTRIC CO., Ltd. May 5, 1954 (Feb. 6. 1953], No. 3409/53. Class 38 (2). A rectifying circuit which may comprise a mercury arc rectifier 10 supplied from a threephase supply 11 through transformer 13 and feeding load 12, includes a transformer 17 having windings carrying respectively the main rectified D.C. and D.C. proportional to the main A.C. derived through rectifier 22. This latter D.C. flows through the right half of the primary winding of transformer 24, but the flux produced by it is counterbalanced by the flux developed by D.C. flowing through the left half of the winding, a resistor 23 being in series to balance the resistance of the winding of transformer 17. Transformer 24 is normally saturated by a steady D.C. in winding 25 but when a backfire occurs in rectifier 10, the flux balance in the core of transformer 17 is upset, and this flux change drives current through the primary winding of transformer 24 in such direction that its core is desaturated and preferably saturated in the reverse direction. A voltage pulse is produced in winding 26 which fires thyratron 27 so that the normal bias supplied to the grids of rectifier 10 is driven to cut off value by the volt drop in resistor 19. A warning device may be operated by the pulse.

Title: Improved method of and apparatus for effecting contact between incompletely miscible liquids
IPC: B04B5/06
Filed: 1936-02-05
Abstract: <PICT:0454994/III/1> <PICT:0454994/III/2> Contact is effected between two incompletely miscible liquids in a rotating spiral passage; the heavier liquid travels outwards from the centre while the lighter liquid travels inwards towards the centre.  The apparatus may be used in the refining of oils with sulphuric acid, the extraction of oils with solvents such as liquid sulphur di-oxide, nitro-benzene, phenol and the like, or in the dehydration of organic substances and other purposes where action between immiscible liquids is desired.  A frame 10 supports a casing 11 which contains a rotor 12 attached to a hollow shaft 13 which passes through a stuffing box 14 on the casing 11.  The rear plate 18 of the rotor carries a spiral strip 19 forming a passage 20 which communicates with the space in the casing 11 by apertures 22 in a retaining cylinder 21.  The front plate 23 of the rotor is removable and has a groove to receive the strip 19; The passage-way may have irregularities to secure agitation of the heavier liquid.  The hollow shaft 13 of the rotor extends through the bearings and opens into a chamber 16, while a stationary pipe 38 passes through the hollow shaft from the centre of the spiral to the pipe 40.  An outlet 30 at the bottom of the casing 11 leads to a float chamber 31.  The acid or other heavy liquid is supplied through the pipes 40, 38 to the centre of the spiral and moves outwards as a layer on the strip 19.  The oil or other light liquid is supplied to the casing 11 by the inlet 29 and moves inwards under its applied pressure in contact with the acid.  The clean oil passes from the spiral to the hollow shaft and the chamber 16, while the acid and sludge pass to the float chamber 31.  When the level in this chamber is sufficiently high, the float 34 is lifted to operate the compressed air control valve 35, which in turn causes the valve 33 to open for the discharge of the heavy liquid.  The end 27 of the casing 11, and the outer wall 23 of the rotor may be made of transparent quartz or a suitable glass to permit acitinic rays to enter the passage-way to assist the action.

Title: Improvements in or relating to Ordnance Breech Mechanism.
Inventor: ASBURY DORSEY FROST
IPC: F41A3/08
Filed: 1917-03-12
Abstract: 105,067. Asbury, D. F. March 15, 1916, [Convention date]. Ordnance breech mechanism. - Relates to screw breech mechanism in which the breech-screw receives an angular, as well as a longitudinal, movement with respect to the swing- ing carrier, means being provided, operating between the breech-screw and the carrier, for converting one of the two movements of the breechscrew into the other. The invention consists in converting each of the two movements into the other, the ratio of the movements varying during the conversion. The invention is shown in Figs. 2 and 3 applied to mechanism as described in Specification 6739/12, in which the breech-screw B is rotated by a hand. lever 18 operating a crankshaft 16 and cross-head 17, the breech - screw being shown fitted with a de Bange obturator 12 having a mushroom head 11, the forward movement of which is prevented by means of a nut 13, cup 14, and rods 15 bearing against the breech-screw, as described in Specification 100,965. According to the present invention, the carrier is fitted with a radial extension 19 having variable-lead cam-surfaces 20, 21, with which en. gage rollers 27, 26 carried by a radial pin 25 fixed to the breech-screw. When the carrier is being closed, the cams, owing to the forward momentum of the breech-screw, convey a rotary and longitudinal movement to the breech-screw, and also retain the carrier against the breech A of the gun, in which position a spring catch 31, Fig. 3, is removed from the path of the roller 27. When the breech-screw is rotated for unlocking by the hand-lever 18, the cams cause the breech-screw to move rearwardly in the carrier and finally initiate its opening movement, the projection 22 preventing rotation of the screw when the carrier is open. When the breech is opened and closed slowly, the carrier is held against the gun by the engagement of a roller 28 with a cam 29 on the gun. The arrangement of parts shown facilitates disassembling, as the carrier may be disconnected from the breech-screw after removing the carrier hinge-pin, the nut 13, and the pin 25.
