Title: Improvements in and relating to the wetting of solids
Inventor: MENZIES JAMES DONALD
IPC: G01G19/22
Filed: 1961-09-23
Abstract: 946,618. Weighing apparatus. SIMONACCO Ltd. Sept. 21,1962 [Sept. 23, 1961],No. 34148/61. Heading G1W. Relates to a means for automatically controlling the amount of liquid or liquid suspension fed on to a discrete material in proportion to the weight of the material. The application of the invention to the treatment of slurry in coal washing plants is mentioned. Liquid is fed through pressure operated normally closed valve 16a (Fig. 1) on to a dry discrete material 11 on a belt conveyer 13. A cranked lever 16 pivoted at 23 carries a roller 21 urged against the belt by a spring 22. The lower end of the lever bears on a valve rod 24 of a pressure regulator 25 (Specification 722,993 and Fig. 3 not shown) having a diaphragm 28 normally held in equilibrium by springs 30, 31. The lower chamber of regulater 25 is open to atmosphere or to a fluid reservoir. In a conduit 38 between a source of fluid under pressure (not shown) and the regulator 25 is a trickle valve 41 and a fluid control valve 39 (see Specification 815,624) which comprises a pump driven by a pulley 40 engaged by belt 13. The fluid pressure produced by the pump passes to the regulator 25 and when the belt is empty the lever 16 acting on valve rod 24 raises a valve head 29 to open a central aperture in the diaphragm 28 thus allowing the fluid to escape to the lower chamber of the regulator and out through the aperture 32 thereof. When the belt is loaded the aperture in the diaphragm is wholly or partially closed as the lever is deflected by the sag of the belt and the pressure in the upper chamber of the regulator 25 thus varies in proportion to the load on the belt. This pressure is communicated to a diaphragm 37 of the liquid supply valve 16c to control the opening of the valve and hence the flow of liquid to the material on the belt. A further control may be provided whereby, if it is a liquid suspension which is sprayed on to the material, the more solids in the suspension then the more liquid is fed on to the material 11.

Title: Refining of metal and alloys
IPC: C21C5/42
Filed: 1964-08-21
Abstract: <PICT:1064826/C6-C7/1> Metal or matte is refined by flowing it through a refining chamber and injecting oxygen-containing gas into or on to the flowing metal agitate it, inducing a counter-current flow of slag in at least part of the refining chamber and flowing the slag formed in the refining chamber into a slag settling chamber in which substantially quiescent conditions are maintained.  In the apparatus shown the crude metal or matte is fed into the refining chamber 10 through an inlet 34 and the refined metal is withdrawn at 15.  Oxygen-containing gas is injected into the metal through tuyeres (36), Fig.6 (not shown) and fluxes may be entrained in the gas or introduced through ports 38, 39.  The slag moves counter-currently to the metal, passes into the slag settling chamber 18 and is discharged at 25.  The chamber 18 has a sloping floor so that any entrained metal which settles from the slag is returned to the refining chamber.  In further forms described, the slag settling chamber is arranged at right angles to the refining chamber and communicates with it either midway between the inlet and outlet openings, Fig.2 (not shown) or adjacent the inlet opening, Fig.7 (not shown). Alternatively, the two chambers are arranged parallel to each other and are interconnected at one end, Fig.8 (not shown).

Title: Improvements in or relating to line protector relays
IPC: H02H7/30
Filed: 1929-11-13
Abstract: 343,507. Induction relays ; protective cut-out systems. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Nov. 13, 1929, No. 34707. Convention date, Nov. 29, 1928. [Class 38 (v).] Relates to an induction - type distance relay, for electric protective purposes, of the type in which a unif ormly-moving contact k moves towards a counter-contact e carried by the induction disc B which under the control of current and voltage windings c, d, assumes a position in accordance with the resistance of the line. The induction disc is influenced by an additional current torque assisting that of the first current winding and obtained from a solenoid v carrying a current winding acting on a sickleshaped iron armature n. This additional torque compensates for the saturation of the iron (on which the ordinary winding is wound) with very heavy currents. In the arrangement shown, on overload the relay A allows its contacts a to close, thereby energizing the solenoid of the relay C which attracts its armature and by putting a tension on the spring m rotates the travelling contact k through the gear-wheels shown. The solenoid also closes contacts which complete the circuit of the voltage winding d of the distance relay, the induction disc of which under the action of the voltage winding and of the main and compensating current windings takes up a position correctly representing the resistance of the line. When the contact k reaches the contact e on the disc, the circuit-breakers are tripped. A protective circuit in which the relays described are associated with an energy-direction relay to ensure tripping only with a particular direction of energy is described, Fig. 2 (not shown).

Filed: 1938-11-30
Abstract: 521,984. Television. GENERAL ELECTRIC CO., Ltd., and EDWARDS, G. W. Nov. 30, 1938, No. 34884. [Class 40 (iii)] Relate to receivers of television signals of the kind shown in Fig. 1, and consists in means for causing the frame time base to be actuated at one of the interruptions a, b, ... of the frame impulse, said means being adapted to superimpose on the synchronizing impulses during their passage to the frame time base a disturbance starting substantially simultaneously with the start of one frame impulse and ending before the next frame impulse, and such as to cause at least one pulse corresponding to an interruption to rise above a critical level above which no such pulse would rise if the said disturbance were not present. The synchronizing impulses may previously be converted into pairs of oppositely directed pulses by a resistance capacity circuit having a time constant much less than T, Fig. 1. In the apparatus shown in Fig. 6, the synchronizing impulses are separated from the picture signals in a known way by a biassed rectifier V1, the main load of which is indicated at 8. These impulses are transmitted through condensers C and resistances R to a line time-base L and a frame time-base F. Moreover, the primary 9 of a transformer is inserted between the valve VI and the point 0, and the secondary 10 between the condenser C and the valve F. The stray capacities C<SP>1</SP> of this transformer give it a time constant of the order of the duration of a frame pulse and this produces an impulse which is superimposed on the impulses transmitted by condenser C ; so that the impulses reaching the valve F are of the form shown in Fig. 5a or Fig. 5b. The frame timebase is biassed to operate at the peak a or b ... in these figures which first reaches a given level. Specifications 484,412 and 514,807 are referred to.
