Title: Ion exchange method
IPC: B01J47/10
Filed: 1968-07-22
Abstract: 1,212,727. Phosphoric acid. MULTI MINERALS Ltd. 22 July, 1968 [13 Sept., 1967], No. 34769/68. Heading C1A. [Also in Division B1] Phosphoric acid is produced by contacting a phosphate, preferably monocalcium orthophosphate, with sufficient strong acid ion exchange resin in the hydrogen cycle to dissolve the phosphate and contacting the resultant mass with a further quantity of the ion exchange resin. The phosphate may contain up to 14% by weight of free phosphoric acid or in a preferred embodiment monocalcium orthophosphate in a dry undissolved state may be contacted with the ion exchange resin in at least partially dehydrated state.
Patent GB-838147-A (GB)
Title: Improvements relating to methods of reducing iron ores
IPC: C21C7/10
Filed: 1957-11-07
Abstract: 838,147. Extracting and refining iron. DORTMUND - HORDER - HUTTENUNION A.G. Nov. 7, 1957 [Nov. 8, 1956], No. 34779/57. Class 72 Iron ore is reduced by continuously delivering ore and slag forming materials to a highly carburized iron melt and replacing the carbon as it is consumed in the reduction of the ore, in which the iron melt which effects the reduction is sucked up in portions into an evacuated vessel, carburized there and returned to the melt. Vacuum vessel 4, which is filled with metal from bath 3 either by being raised and lowered or by variation of the vacuum within it, has a charging device 7, 8 for the addition of carburizing agents as well as deoxidizing and denitriding agents and fluxes. Ore is added through pipe 9 above burner 10 and waste gases may be drawn off through said pipe to preheat the ore. When a desired quantity of iron has been reduced, the process of sucking in and returning portions to the melt is continued without further carburization and the melt refined to steel by further addition of ore. The process can be carried out other than in the open hearth furnace such as in shaft furnaces with deep baths. Specification 801,518 is referred to.
Patent GB-472733-A (GB)
Title: Improvements in or relating to radio systems for directionindicating and position-finding
IPC: G01S1/44
Filed: 1936-12-18
Abstract: 472,733. Directive wireless signalling ; valve circuits. LORENZ AKT.-GES., C. Dec. 18, 1936, No. 34854. Convention date, Dec. 20, 1935. Addition to 447,707. [Class 40 (v)] Relates to circuits of the type described in the parent Specification, for counting the number of signals of two different kinds received from a rotating radio beacon. The signals applied to the counting circuit each consist of a positive and a negative impulse, the sign of the first impulse of the pair determining which kind of signal is being received, and are applied in push-pull to a pair of discharge tubes R1, R2. The first impulse of the pair triggers one or other of the tubes R1, R2 to discharge the condenser C in the common anode circuit through a counter Z1 or Z2, the second impulse being ineffective owing to the resulting lack of anode voltage on the other tube. According to the present invention the condenser C is recharged through a valve S from the source A and the counting impulse through valve R1 or R2 acts through a transformer T to disable valve S for a time dependent upon the values of the condenser C1 and resistance W1 in its grid circuit. The condenser C is thus charged rapidly and only a short time before the receipt of the following signal, so that interfering impulses in the intervening period are ineffective to actuate the counters Z1, Z2. The potential to which the condenser C is charged is limited by a glow discharge tube G connected in shunt.

Title: Improvements in and relating to echo-sounding apparatus for use on noisy aircraft
IPC: G01S1/72

Abstract: 404,594. Echo - sounding apparatus. FLORISSON, C. L., 11, Rue de Cronstadt, Courbevoie, Seine, and SOC. DE CONDENSATION ET D'APPLICATIONS MECANIQUES, 42, Rue de Clichy, Paris, both in France. July 29, 1932, No. 34880 /33. Convention date, July 30, 1931. Divided on 404,383 and addition to 389,646. [Class 118 (ii).] In echo-sounding apparatus for use on aircraft as claimed in the parent Specification, the depth is directly indicated by the position of a pointer at the instant the echo is heard. As shown in the Figure, a clockwork driven cam 13 closes contacts 16 controlling the emitter 17 once in each revolution, the contacts being closed when a pointer 49 secured to the cam-shaft 52 is at the zero of a scale 50. The operator notes the position of the pointer 49 when the echo is heard and sets a marking pointer 51, actuated by a handle 53, to this position, the dial being marked to indicate depths directly. The position of the marking pointer 51 may be transmitted to a distant pointer 58 by any known means such as the wire 59, the distant pointer being illuminated by a lamp 64 which is lit by the operator closing a switch 63 when he has correctly positioned the marking pointer 51. The dial and pointer are translucent so that the pointer and graduations cannot be seen unless the lamp is lit. Specification 404,383 is referred to.

[Class 135] A governor mechanism for steam turbines, Diesel engines and the like of the kind comprising a spring loaded servomotor piston subject to a variable control pressure produced by an element arranged to move in accordance with some governed quantity such as the speed of the power unit or the discharge pressure of a pump driven by the said power unit, is fitted with means wherein the control pressure acts to increase the movement of the said element after an appreciable time interval. In the form shown the main valve is actuated by a spring-loaded piston g<1> under the control of a piston valve having a beat b<1> narrower than the port:.d with which it co-operates. The valve is actuated by a centrifugal governor a loaded by a spring i tensioned by a variable fluid pressure acting on a piston k, and controlled by a hand operated valve l and a leak through an adjustable throttle m from the conduit connecting the control valve to the power cylinder. The invention may be applied to the pressure governed pass-through valve gear of a pass out turbine. In the case of a Diesel engine the relay is adapted to operate means for regulating the amount of fuel injected into the engine cylinders.

[Class 103 (v)] [See also Groups XXXI and XXV] Ball - and - socket coupling means for road and rail vehicles comprises a ballended shank 2 and a socket member comprising a pair of hingedly connected jaws 4, 4<a> on a shank 5 carrying a locking ring or sleeve 9 which is slidable over the hinged connection to hold the jaws closed, the surfaces being tapered, if desired, to take up wear &c. The sleeve may be pressed into action by a spring 10 or may be retained in position by a detent adapted to engage recesses in the shank. The ball and socket shanks 2, 5 may be respectively anchored, rigidly or resiliently, to the vehicle ends 3, 8, or each vehicle may carry a socket member for co-operation with a loose rod or link having a ball at each end. The ball 1 and jaws 4, 4<a> may be shaped as shown in figure 4 to allow endplay and to accommodate the head 16 of a spring-pressed rod 17 adapted ordinarily to apply the trailer brakes in the event of over-running ; when however it is desired to back the vehicles, such endplay may be prevented by swinging a forked arm 28 or dropping a saddle member into position, as shown, behind a loose collar 24 causing this to bear against the open end of the socket member. An automatic coupling is shown in figure 5 wherein, when the parts are uncoupled, a rod 31, slidable in an axial bore in the socket shank, is pressed forward by a spring 32, thereby lifting a loose or pivoted stop member 36, (previously seated in a recess 37), to hold the slidable collar 9 retracted. On re-coupling, the ball presses back the rod 31 whereon the stop member 36 drops or is pressed back into the recess 37 releasing the collar 9 which, under the pressure of the spring 10, lifts the jaw 4<a> and re-establishes the coupling. A pin 33 passing through a slot in the rod 31 limits the protrusion thereof.
