Title: Improvements relating to Topping-Up Electric Storage Batteries.
Inventor: KIRKPATRICK JOHN
IPC: H01M50/609
Filed: 1966-04-05
Abstract: 1,151,844. Topping-up device. ELECTRIC POWER STORAGE Ltd. 4 July, 1967 [5 April, 1966; 10 June, 1966], Nos. 15139/66 and 25984/66. Heading H1B. The invention comprises a device for topping- up a battery to a predetermined level in which the upper part of each cell above the desired liquid level is divided by a depending partition into a vented compartment from which air can escape and an air-locked compartment connected through a filling tube including an airlock to a filling duct common to all cells so that when the liquid surface rises above the bottom of the partition further rise in the air-locked compartment is prevented and pressure heads build up in the vented compartment and filling duct, characterized in that the liquid in the duct when filling is complete may flow through a constricted passage into one of the cells referred to as "the drain cell" Fig. 1. illustrates a 3 cell lead-acid battery having 3 covers each extending over all 3 cells. Cover 11 is moulded to form trough 14 surrounded by wall 19 and sloping at the bottom to drain 15 constricted by float indicator 32 and leading to the central drain cell. Filling openings 16 for each cell project upward into the trough, the opening of the drain cell projecting above the other two. Each cell is also provided with a vent 22, the lower end of which opens into the cell and the upper end of which (not shown) opens into the upper part of trough 14. A second cover 12 fits over trough 14 and from it depend annular partitions 17 which with projections 16 form air-locks to each cell and clips 20 which hold the cover in position. A third cover 13 covers the whole of top of the battery except terminals 28 and filler cap 25 which holds it in position. When filling is required, as indicated by float indicator 30 visible through window 34 in the cap, the cap is unscrewed and water poured into trough 14. From here it will flow into the outer two cells until the lower ends of the two vents are covered when the level will rise in the trough until it begins to fill the centre cell. When filling is complete as indicated by a rise in indicator 30 the cap is replaced and the liquid in the trough slowly drains through constricted passage 15 into the central cell. Further drain constrictions are shown in Figs. 2 and 3. In the former the valve 42 is normally depressed by cap 25 so that water can drain into the central cell. However during filling cap 25 is removed and the valve is raised by spring 44 to close the drain. In Fig. 3 the valve 52 is raised and lowered by the indicator float to which it is connected by a lost motion joint.

Abstract: 440,945. Discharge lamps. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. Sept. 20, 1935, No. 26113. Convention date, Sept. 20, 1934. [Class 39 (i)] In a positive column discharge device, a series of thermionic electrodes 11, 12a, 12 are arranged along the tube to facilitate the starting of the discharge ; the heating resistances of the electrodes are in series and this combined heating circuit is in parallel with the discharge gap. As shown, with equipotential electrodes, the oxide-coated emitting surfaces have connections 20 to the molybdenum connecting leads for the heating resistances, the leads being encased in alumina tubes 25. The four electrodes 11, 12a have sharp-edged, starting - anode pieces 24 of tungsten, which start a local discharge at the commencement of running. With the connections as shown, the potential drop will be greater between the top electrole 12 and the right-hand electrode 12a than between any other pair of adjacent electrodes, and an intermediate discharge will be first obtained across this gap to be followed by other intermediate discharges and finally by a discharge across the main gap between the electrodes 11 ; when this takes place the electrodes 12, 12a go out of action. In a modification, with three electrodes in a U-tube, the upper electrode is arranged across the tube, and the leads are taken outside the tube ; in another arrangement some of the electrodes may be directly heated. The filling may be of sodium with an addition of neon or argon whose partial pressure is between 1 to 7 mm. The lamp may be enclosed in an outer envelope.

Abstract: 1434711 Linear motors; cooling stator windings MITSUBISHI DENKI KK 12 June 1974 [12 June 1973 14 June 1973 3 Dec 1973 18 Feb 1974] 26125/74 Heading H2A A cooling arrangement in a linear motor having a stator winding around a tubular member, comprises a chamber holding a coolant liquid in which the stator winding is immersed and a condenser which condenses the coolant vapour and returns the condensate to the liquid body. In an accelerator for a shuttleless loom, the three-phase winding 22 is wound around an insulated steel tube 16 of rectangular crosssection through which the carrier passes while being accelerated by the moving field established by the winding. The coil groups are separated by plastics spacers 26 along the tube which passes through a cooling chamber 12 containing the coolant, "Freon" (Registered Trade Mark), which completely covers the winding 22. A bellows 18 seals the tube 16 at one end to the chamber 12 to allow for differential expansion. Above the cooling chamber 12 is a condenser 102 connected by conduits 36, 38 thereto through which vapourized coolant passes, is condensed by the action of cooling water passing through a coil 106 mounted by supports 108 on a central bore 104 and is returned to the coolant liquid body. The stator winding is manufactured by insulating the steel tube 16 with tape and winding over it insulated copper wire to form each coil group. Each coil group is separated from the next group by a "Bakelite" (Registered Trade Mark) spacer 26 which may have horizontal or vertical grooves and/or notches in its central aperture to aid the release of vapourized coolant from the winding interior (Fig. 4, not shown). In cases where thin spacers are used to increase the winding efficiency, grooves are not feasible and a spacer may be provided around which the coil is wound providing gaps under the winding (Fig. 6, not shown). The windings may be formed as radially layered coils of one conductor width axially spaced along the tube (Figs. 7, 8, not shown) or radially spaced, concentric single layer coils (Fig. 13, not shown) both arrangements providing ample spacing for the escape of vapourized coolant. When magnetic cores are provided for the windings (Figs. 15- 17, not shown) the upper portion may be pierced to allow vapour to escape or the two halves may be mounted laterally of the tube with upwardly slanting ducts from the winding surface (Fig. 18, not shown). In modified arrangements of the condenser (Figs. 19-20; 21-22, not shown) the condensing coil is arranged either vertically or horizontally with the bends in the coil arranged outside the condensing chamber to improve cooling. In these arrangements, the stator winding lies at the bottom of a single chamber also holding the condenser, and vapourized coolant rises to be condensed and caught in alternately sloping troughs which return the condensate to the coolant body or the rising vapour is constrained to follow a serpentine path around the cooling coil by means of appropriately placed baffles.

Title: Improvements in or relating to telephone dials and to telephone subscribers apparatus incorporating telephone dials
Inventor: PUCKETTE CHARLES CLARKE
IPC: H04M1/677
Filed: 1959-07-30
Abstract: 889,542. Impulse transmitters. GENERAL ELECTRIC CO. Ltd. July 20, 1960 [July 30, 1959], No. 26215/59. Class 40 (4). In an impulse transmitter of the dial type, an auxiliary spring set is provided whose contacts are actuated only when the return motion of the finger-plate is from a predetermined digit; the said contacts short-circuiting the impulsing contacts except when the predetermined digit is dialled. The impulse transmitter and its normal operation is exactly the same as that described in Specification 518,721. When the predetermined digit, i.e. 9, is dialled a member 11 engages a pin 9 projecting from one face of an auxiliary cam 8, which is free to rotate at one end of shaft 1, and so causes cam 8 to rotate. In so doing, cam follower 14 which is attached to contact spring 12 of the auxiliary springset 6, falls into the depression 15 on cam 8 and contacts 7 are separated so removing the short-circuit across the impulse contacts 4. During the return motion of the dial, nine impulses are sent to line, the member 11 then engaging pin 10 so that cam 8 is returned to its normal position. If the digit 0 is dialled, cam follower 14 rides over a projection 16 on the auxiliary cam 8 so that impulse contacts 4 are again shortcircuited. Spring 17 does not of itself store sufficient energy to return cam 8 to normal from one of its two off-normal positions but it does ensure that the return to normal is rapid once it has been initiated by the engagement of member 11 with pin 10. A keyoperated contact (Fig. 3, not shown), may be placed in series with the auxiliary contacts to allow unrestricted use of the telephone to privileged subscribers.
