Patent GB-630684-A (GB)
Title: Improvements in fluid heating systems
IPC: F24D17/02
Filed: 1946-08-14
Abstract: 630,684. Thermally - actuated valves. BARNES, N., WHITAKER, A., and JESSEL, R. Aug. 14, 1946, No. 24190. [Class 135] A water-heater has the heating means controlled by a device responsive to the pressure difference across a Venturi through which water to be heated flows, the Venturi being provided with a byepass controlled by a valve operated by a thermal device responsive to the outlet temperature of the water. As shown, water from a domestic hot water system or the mains enters a casing 8 at 9 and passes via the outlet 10 and Venturi 12 to the pipe 17 leading to the heatexchanger of the heater and back at 23 to the casing and outlet 24. When the water flow exceeds a certain minimum value, the pressure difference across the Venturi moves a diaphragm to open the gas valve so that the burners are ignited by a pilot light. If the outlet temperature of the water exceeds a predetermined value, the bellows thermostat 21 opens the valve 18 controlling the flow through a pipe 16 byepassing the Venturi, so that the flow is reduced through the Venturi but more water passes through the heater to maintain the predetermined outlet temperature. In a preferred form, when the valve 18 has been fully opened, the flow in the Venturi is insufficient to maintain the gas supply which is therefore cut off. In another modification, when the valve 18 approaches the fully-open position the gas supply is reduced. The water passing to the heater may be controlled by an auxiliary valve. Specification 436,773 is referred to.

Abstract: 606,903. Sliding-clasp fasteners. WINTERHALTER, M. Sept. 22, 1945, No. 24604. Convention date, Oct. 6, 1944. [Class 44] The end coupling of a sliding-clasp fastener is constituted by end members fixed to the two stringers and having disengageable mutually interlocking surface portions restraining the members against relative movement longitudinally of the stringers and perpendicularly to the plane thereof, but permitting ready separation by moving the members apart in the plane of the stringers, the members being secured together by a clamp having two branches each engaging one of the members to prevent separation of the interlocked edges. Thus, to fit a new slider, the clamp only has to be removed and refixed. As shown in Figs. 2 and 3, the end members 5, 6 are formed with surfaces which interengage to prevent longitudinal and lateral separation, the member 5 having a projection 20 engaging in a recess 22 in the member 6, while a projection 25 on the member 6 engages in a recess 26 on the member 5. The members are secured together by a U-shaped metal clamp 30, the branches of which engage in slots in the members, and pass through the stringer tapes, while the central portion 33 is partially sunk in recesses on one face of the members, and serves as a stop to limit the travel of .the slider. When the members are made of thermoplastic material cast on the tapes, the ends of the clamp may be pressed over into the material to secure the clamp; in the case of metal members, notches to receive the upset ends are provided. As shown in Fig. 9, the branches of the clamp may be passed through holes in the members 5, 6.

Abstract: 604,688. Purifying sugar solutions. TATE & LYLE, Ltd., and SIMMONS, C. E. G. Sept. 25, 1945, No. 24879. [Class 127] [Also in Group I] A process for treating sugar solutions with bone char or synthetic resins consists in causing the solid absorbent to flow in countercurrent with respect to the solution and to washing liquid, the travel of the absorbent being provided by an air lift. In the arrangement shown diagram matically, there are three absorption chambers 16, 17 and 18, a sweetening-off chamber 19, and three charwashing chambers 20, 21 and 22. The raw liquor is introduced into chamber 16 through pipe 23. The char absorbent 25 is supplied at the top of the chamber and after passing to the bottom is conveyed by a jet 27 of compressed air, up a tube 28 into a hopper 29 where it is separated from syrup by means of a rake conveyer 30. The char is delivered to the chamber 17 and the syrup is returned by way of pipe 24 to the chamber 16 where it flows with the raw liquor up through the char to a collector 26. Syrup introduced into chamber 17 through pipe 32 together with syrup coming from a hopper 34 associated with chamber 18, flows up through the char to a collector 31. The procedure in chamber 18 is similar to that in chamber 17. The chamber 19 is supplied with wash water from a collector 57 by means of a pump 59 and a pipe 58 and is also supplied through pipe 43 with liquid separated in a hopper 47 from char which is delivered to the chamber 20. The arrangement in chamber 20 is similar to that in chamber 19. Wash water is supplied to chambers 21, 22 through pipes 52, 63 respectively. The char, which has passed through all the chambersby means of air lifts, is delivered finally to a hopper 56 from which it is removed for regeneration. Specification 578,520 is referred to.

Title: Improvements in or relating to the control of vapour arc rectifiers
IPC: H02M7/15
Filed: 1933-09-08
Abstract: 407,619. Rectifying alternating current; transformers. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, CALVERLEY, J. E., 58, Crescent Road, Rowley Park, and EVANS, W. R., Parkfield, Cannock Road, both in Stafford. Sept. 8, 1933, No. 24950. [Class 38 (ii).] In a grid regulated vapour arc rectifier, the instant at which a positive potential is applied to the grids to render the corresponding anodes conductive is determined by adjusting the relative magnitudes of two A.C. voltages differing in phase the resultant of these two voltages whose phase position in relation to the anode voltage is thus determined being applied through glow discharge tubes to the grids. In the case of a 6-phase rectifier a, three grid transformers respectively excited by primaries 7, 8, 9 associated with the supply network b are employed. Secondaries 10 .. 15 arranged in pairs on the same limbs as the primaries provide voltage components of fixed amplitudes, and secondaries 16 .. 21 arranged in pairs on outer core limbs are adapted to provide voltage components of variable amplitude in dependence upon the current flowing in D.C.-excited coils 4, 5, 6 arranged on the third limbs and adapted to divert a variable proportion of the flux due to the primaries through the limbs carrying the secondaries 16 ... 21. Each grid circuit includes one of the secondaries of fixed voltage, e.g. 12, and one of the secondaries of variable voltage, e.g. 16, the two voltages being 60‹ phase displaced. Each grid circuit also includes a glow discharge tube 22 and an adjustable proportion of a potentiometer 25 associated with a battery 28. The potentiometer tappings are adjusted to take account of inequalities in the characteristics of the tubes 22 so that each tube breaks down at the same value of the resultant A.C. voltage due to the components derived from the two secondary windings. The instant at which this value is attained is varied by varying the current in the coils 4, 5, 6 either manually, or automatically by connecting the coils across a shunt 29 in the rectifier load circuit. The coils 4, 5, 6 are connected in series so that A.C. voltages induced therein by flux due to the primaries 7, 8, 9 balance out. Alternatively, the three cores may be arranged with their third limbs embraced by a single coil 4 as shown in Fig. 4. Where two or more rectifiers operate in parallel, the load is connected to the terminals + L, - L, and the terminal - T1 on the rectifier side of the shunt 29 is connected to corresponding terminals - T2, - T3 etc. of the parallel operating rectifiers as shown in Fig. 5.
