Title: Arrangement for controlling the electrolyte level in a battery or accumulator
IPC: G01F23/00
Filed: 1956-12-27
Abstract: 808,963. Storage batteries. YARDNEY INTERNATIONAL CORPORATION. Dec. 27, 1956 [Dec. 27, 1955], No. 39352/56. Class 53. A storage battery in which one or more restricted electrode compartments, e.g. those containing the positive electrodes 18, are isolated from a principal electrode compartment, e.g. that containing the negative electrodes 20, by an envelope 19 of semi-permeable separator material open at the top but projecting above the normal electrolyte level in the principal compartment incorporates an inflatable bladder 26 so that inflation of the bladder raises the liquid level in the principal compartment and causes some electrolyte to overflow into the restricted compartment. The positive plates 18 are of silver oxide and are each wrapped in semi-permeable material 19, and the negative electrodes are of zinc. Recesses 37 are formed along the top of the wrappings and a non-conductive corrugated member 33 on the top of each plate 18 keeps the top of each wrapping open. A partition 25, fitted loosely within grooves 30, 301 in the,walls of the battery, extends to the top of the wrappings 19 and defines a well B containing the bladder 26. When charging of the battery is started the bladder 26 is deflated as shown at 26<SP>1</SP> and the level of electrolyte in the well B is the same as that in the principal compartment, viz. H. During charging, electrolyte passes from the restricted compartments around the electrodes 18 into the principal compartment containing the electrodes 20 and thence around the edges of the partition 25 into the well B where the electrolyte level rises to H<SP>1</SP>. Charging is then stopped and the bladder inflated to force some electrolyte over the partition 25 into the principal compartment and thence over the tops of the wrappings 19 into the restricted compartments. The bladder is then collapsed and the charging continued. After charging the bladder may be partially inflated to seal the partition 25 in the grooves 30, 30<SP>1</SP> and during discharge may be completely deflated to allow electrolyte to pass from the well B into the principal compartment.

In one embodiment (Fig. 1, not shown) each heat exchanger comprises a bundle of tubes (13) supported in an annular chamber defined between inner (9) and outer (6) sleeves. Coolant inlets (6a) conduct hot sodium from the core (1) into the chamber so as to flow downwardly over the tubes (13) through which a secondary coolant is passed. From the base of the exchanger, the sodium passes up to inlets (7a) of a pump (7) which is surrounded by the exchanger. The cold sodium discharged from the pump is conveyed to an inlet plenum (2) below the core (1) through a closed pipe (8). The heat exchangers and pumps are distributed at equal angular intervals radially outwardly of the core (1). In another embodiment (Fig. 2, not shown) the heat-exchangers comprise bundles of tubes (13a) mounted in an annular chamber surrounding the core (1) and defined by annular walls (22, 23) of different radii. The exchangers alternate with the pumps (7) in a regular angular distribution about the core (1). The inlets (7a) to the pumps are separated by means of a hood (21) from the secondary coolant emerging from the heatexchangers into a chamber thereabove. The pumps discharge cold sodium to the core inlet plenum (2) via closed pipes (8). The inlets to the heat-exchangers are defined by apertures (6a) at the upper edge of the inner (23) of the two annular walls.

Abstract: 872,608. Winding thread. MACKIE & SONS Ltd., JAMES. Dec. 11, 1958 [Nov. 9, 1957], No. 40092/57. Class 120(2) In the winding of tapered cross-wound packages in machines of the surface winding type, the formation of ribbons is reduced or eliminated by arranging for the taper of the package and that of its driving roller to be oppositely directed and by rocking the package during the winding so as periodically to vary the driving ratio between the driving roller and the package. The machine shown has a driving shaft 10 having fixed thereon at spaced intervals tapered driving rollers 12. The package is formed on a tapered centre 21 which is frictionally held on a mandrel 22 mounted to rotate on a spindle 24 fixed to an arm 26. The arm 26 is supported in a bracket 32 free to turn on a pin 38 and counterweighted by a weight 40. The arm 26 also carries a quadrant 36 which is formed with a slot 42 through which projects a pin 44 fixed to a shaft 46 which is axially reciprocated by a cam 48. Reciprocation of shaft 46 causes rocking of the package so that it is driven by the driving roller first at one of its ends and then at the other. To wind packages of different taper angles the mandrel 22 is removed and replaced by another having the appropriate taper.
