A lug 30 on the plate 10 engages a recess in the plate 12 to secure alignment.
Patent GB-481892-A (GB)
Title: Improvements in and relating to the production of titanium dioxide pigments
IPC: C01G23/053
Filed: 1936-09-18
Abstract: In the production of titanium dioxide pigments an aqueous solution of titanium tetrachloride is hydrolysed in the presence of divalent negative ions derived from a substance added to the solution in a proportion not exceeding 0,1 mol to each mol TiO2 present, hydrolysis being effected in the absence of suspended insoluble material.  By this means readily filterable titanic hydroxide is precipitated.  The product has the rutile crystalline structure and is calcined to yield a pigment. Hydrolysis may be carried out by adding the titanium tetrachloride solution to hot water containing sulphuric, tartaric, or oxalic acid or one of their alkali metal salts and heating the mixed solutions.  Specifications 274,072, [Class 95], 308,725, and 309,051, [both in Class 1 (iii)], are referred to.

Title: Improvements in or relating to liquid dispensing installations
IPC: F16K31/48
Filed: 1962-07-03
Abstract: 1,017,511. Mixing fluids in flow in proportionate quantities. TAKHEIM CORPORATION. July 3, 1962 [July 3, 1961], No. 25540/62. Heading B1C. [Also in Divisions A4 and F2] High octane fuel is pumped at 29 through meter 33, proportioning valve 35, limit valve 37 and inner concentric hose 53 and low octane fuel is similarly pumped at 13 through 17, 19, 21 and external concentric hose 51, the two fuels mixing in a small chamber adjacent the outlet nozzle. The operator turns knob 369 so that when a pointer overlies a mark I pilot valve 195 in series with pilot valve 123 is cam actuated to close the limit valve 37 so that only low octane fuel is delivered. When the pointer overlies a mark 10 pilot valves 189, 121 close limit valve 21 so that only high octane fuel is delivered. When the pointer overlies a number between 1 and 10 the pilot valves remain unactuated and the limit valves stay open to deliver a mixture of the fuels in a proportion determined by the amount of rotation of the knob. This rotation actuates a stepping mechanism whereby when the nozzle is permitted to be lifted off its holder 841 by turning switch arm 710 horizontally, electric motor 145 acts through differential 147 to drive the transfer mechanism 155 of a cost variator 131 and the percentage setting gear 335<SP>1</SP> driving the blend variators 97, 99 determining the proportion of the two fuels and also drives gears in stop mechanisms 159, 167 actuating stepping pinions 555, 557 and a follower mechanism 547 for stopping motor 145 when the blend variators have been set to deliver the selected blend and the corresponding price per unit has been set on the indicator 141 via cost variator 131. The blend stop gear 489 also drives through gear shaft 615 a positioning mechanism 171 which acts through differential 111 to position a lever 113 adjusting valves 19, 35 to deliver the blend set on the blend variators. After the blend and price setting the follower mechanism 547 switches in motor 187 to reset the cost and gallons registers 139, 95 to zero after which a circuit is completed to start the pumps 13, 29. On operating the dispensing nozzle the flows through meters 33, 17 drives the differentials of the blend variators to operate the cost and gallons registers and through output gear 109 and differential 111 maintain or adjust the positions of the proportionating valves 19, 35 should variations occur in the flows. Should a flow variation become too great a cam 119 operates the pilot valves 121, 123 to close the limit valves 21, 37. Switch lever 710 locks the blend knob 369 before starting motor 145 and indicator 173 shows the blend.

Title: Improvements in or relating to electric supply systems
Inventor: FRIEDLANDER ERICH SIEGFRIED
Filed: 1957-08-15
Abstract: 845,223. Rectifying. GENERAL ELECTRIC CO. Ltd. July 31, 1958 [Aug. 15, 1957], No. 25786/57. Class 38 (2). A three-phase rectifying system comprises a grid-controlled mercury arc rectifier 1 whose six anodes are connected to secondary windings 5 the centre points of which are connected to a three-phase interphase transformer 11 having a saturable core. Two equal opposing control windings 12, 13 are provided on the core and are included in a circuit with a rectifier 15, D.C. sources 14 and 17, a resistor 16 and a signal source 8 which supplies a grid control network winding 7. With small values of signal voltage 8 the values of the voltages 14, 17 and 8 are such that the rectifier 15 is non-conducting and current flows through the two windings 12, 13 in series so providing no saturation of the core. Beyond a predetermined value of signal voltage the rectifier 15 becomes conductive whereupon different currents flow in the windings 12, 13 and saturation of the core arises which varies the alternating voltage supplied to the rectifier. The D.C. source 17 is connected with current transformers 19 whose primary winding carries the load current so that the current through winding 13 is proportional to the load. This compensates for the lowering of voltage which would arise with increasing load current. At signal voltages below the predetermined value the voltage is solely determined by grid control, and the voltage drop in the resistor 16 is compensated by a winding 20.

A sealing ring assembly of the kind comprising two co-operating members 21, 29, Fig. 1, with coacting faces to form an annular recess to take a resilient 0-ring 34, has at least one of the members parted radially and the 0-ring also parted at the same point, the ends of the 0-ring being formed with lateral extensions lying transversely of the circumferential direction of the 0-ring and arranged for mutual abutment within the radial division of the member. The assembly seals the space between an outer member 22 and the floating sealing ring 21 of a turbine, the ring 21 having an annular sealing face 23 which is supplied with lubricant from a groove 50 in the sealing ring 29 by passages 24, 26. The annular oil channels 25, 50 are sealed by the 0-rings 34 which lie in grooves formed on the inner, outer, or both cylindrical surfaces of the ring 29, which itself may be built up of two ring sections arranged side by side. The sealing ring assembly is capable of being introduced transversely into position around the turbine shaft 11 by dividing the ring 29 into two or more parts as shown in Figs. 2, 7, 8. In an embodiment having an internal 0-ring 34, Fig. 7, side extensions 40 are formed on the 0-ring which carries further extensions in a circumferential direction to engage with recesses formed in the opposed radial faces of the ring 29. Figs. 2 and 8 show alternative methods of securing the 0-ring ends by forming hook-like extensions 38 which engage holes 36 in the radial faces of the ring 29. In a further modification, Fig. 6, not shown, the 0-ring has only one radial joint.

An installation for the manufacture of panels, walls, floors &c. of prefabricated constructions incorporates mixers 1, 2 and 3 which work the material, usually asbestos, cement, and water, and feed reservoirs 12, 13 and 14. A receptacle 24, which may be displaced vertically as the mixture is introduced and spread thereon, is disposed in a truck 19 which undertakes excursions 20, 21, 22 to collect the mixture from the respective reservoirs and excursion 23 to dispatch the formed panel. The receptacle 24, which has a perforated absorbing platform 25 to carry the panel, is connected to a vacuum chamber 29 and surplus mixture solution thus removed is returned to mixers 1 and 2 via auxiliary container 32, reservoir 40 and two of the three dosing devices 6, 7, 8 using a compressor 38 and a system of valves. The formed panel is removed from the platform 25, which rises automatically on excursion 23, by a suction plant 54 attached by arms 55-56 to a stand 57-58. Said plant, which is of the helicoidalcentrifugal type comprising aspirators 66 (not shown) and fan may rise and swing round on its stand and stack the plain panel or said panel may be released onto a cloth 72, Fig. 6 (not shown), supported by spaced members 74. In the latter case the members 74 are then brought together on screw axle 75 and a corrugated panel is thus produced and removed by a corrugated suction plant 76, Fig. 7 (not shown). A compressed air system including air feed pipe 4 and air exhaust pipe 5, Fig. 1, may supply the said mixers and the said reservoirs are cyclically closed by pads 17. The mixture is distributed, pressed, and smoothed upon platform 25 by slides 18 of suitable shape situated below the feeders and the fluid recovery section may be washed out using discharge pipe 42.
