Title: Improvements in and relating to storage batteries
IPC: H01M50/147
Filed: 1922-04-18
Abstract: 194,649. Safety Car Heating & Lighting Co., (Assignees of Cole, T. S.). March 11, 1922, [Convention date]. Cells; electrodes; separators.-A storage battery to be formed by the PlantÚ process is constructed to prevent separation of the active material from the metal of the electrode due. to the expansion and contraction on charging and discharging. This is effected by constructing the elements of each electrode with a predetermined ratio of perimeter to cross-sectional area whereby the stresses acting at the contacting surfaces of the active material and the lead forming the electrode do not exceed the tensile strength of lead. Calculations are given in the Specification to show that this ratio must not be less than 90, lengths being measured in inches and area in square inches. Each electrode consists of a number of lead sheets 22 contained in an insulating perforated envelope 19 formed with reinforcing ribs 21 inclined in opposite directions on the two sides. Each sheet 22 is divided by ribs 23<a> into sections, each section being divided into a number of rod-like elements 23 which are spaced centre to centre by a distance not greater than #/2 times the diameter of an element. This ensures that the exposed area of the elements is not Jess than the area of the sheet from which they are formed. A lead collar 25 surrounds the upper ends of the sheets 22 and is supported on ledges 24 formed on the envelope 19, the sheets being thus suspended within but not reaching to the bottom of the envelope. The elements 23 of one sheet are staggered with respect to those of the adjacent sheets. Rubber pins 30 may penetrate the electrode to secure the sheets in position. The cover 32 of the battery is secured to the container as shown in Fig. 4 by a lead strip 39 which is burned to the cover and to a collar 35 fixed to the container. A packing of asbestos 38 is placed below the strip 39. The openings in the cover through which the lugs 33 34 pass are sealed by a bush 42 which is screwed into a sleeve 43 containing packing material 45. A filling opening 47 is normally closed by a plug 48 having gas vents 50 and a chamber 51 for arresting electrolyte.

Filed: 1973-03-06
Abstract: 1418141 Sewing stocking toes; turning inside-out KATATORI MACHINERY WORKS LTD 6 March 1973 [5 Feb 1973] 10918/73 Headings DIG and D1X Toe-closing apparatus comprises a turntable 24 bearing several stocking holding members 55 arranged to spread the toes and carry them successively to a serving head 45. Apparatus. The turntable 24 is supported on a stationary disc 1, and is rotated by a motor 36 via a pinion 37 engaging on internal gear 25. Several e.g. eight holding members are arranged at regular intervals around the turntable. Each comprises a suction tube 56 having vertical portion fixed in a bracket 27, and extending through the table. At positions P 0  and P; the tubes communicate with slots 5 and 6 respectively in the disc and attached suction tubes 52, 53. Fixed to the suction tubes 56 of the holding members are bifurcated upper and lower spaced plates. The upper plate has diverging guides 70. Fingers 66, 67 are arranged between the plates and are guided by members 68, 69. The fingers are projected beyond the end of the holding member by a piston 31 at position P 2 , and further still to wider spread condition by a cam track 32 at position P 3 . Fingers are returned by a hook 34 attached to piston 33 at position P 4 . The sewing head 45 is carried by a bracket 15 depending from a ring 13. It includes a vertically movable locating device 49 which can clamp a stocking against a support member 51. The bracket is carried round through 45 with each holding member in turn, and returned by a piston 42 and spring 44. Also attached to the ring 13 are brackets carrying continuously rotating rollers 79 of stocking drawing-on, and -off, mechanisms 80, 82 and 81 respectively. The rollers can be urged against the stockings on the under sides of the holding members 55. Operation. At position P 0  an operator holds a stocking in front of a suction tube 56 so that the toe is sucked inwards. At P 1  the welt is folded over onto the outside of the holding member, and the material drawn-on by rollers 79; the stocking is thereby turned inside-out. Between P 2  and P 4  the stocking toe is projected and spread by projecting the fingers 66, 67. At P 4  the toe is clamped onto the support 51 by the device 49, and the fingers removed. The toe is closed by a seam while the sewing head travels to P 5 . The material is again drawn onto the outside of the holding member by rotating rollers 79 of mechanism 82. When the holding member reaches P 7  the mechanism 81 draws-off the stocking while suction is applied to tube 56 via tube 53. The stocking is thus turned outside-out and withdrawn. The motion of the turntable may be continuous, or alternatively it may pause with the holding members at each position P 0 -P 7 .

Abstract: 1303862 Valves VENAVCO Inc 9 March 1970 [13 March 1969] 11282/70 Heading F2V [Also in Divisions E1 and G3] A valve for controlling flow into a water closet has a chamber 52 mounted within the closet 12 and closed at the top by a diaphragm 48 which is adjustably connected to the stem 46 of a pilot valve 44. Opening of the hinged valve 18 by pivoted handle 20 through lever 21 and chain 24 allows water to flow from the closet into outlet 16. The water level drops in the closet and the pressure of the air trapped in chamber 52 decreases to allow the diaphragm to open pilot valve 44 and thus pressure from water inlet 30 is communicated to the other side of main valve member 34 via bore 40 to open the valve. Water flows from inlet 30 to outlet 68 into the closet through pipe 70 and to outlet 66 into a tube 74 connected to the closet outlet 16 through the pipe 72. Valve 18 which is held open by float action closes when the level of water in outlet 16 drops. On the rise of water to the required level in the closet the air trapped in the chamber 52 actuates the pilot and the main valves to shut-off supply of water to the closet. In a modification the pilot valve does not seat on the main valve which moves in a bore parallel to the stem 46.

Filed: 1973-03-09
Abstract: 1398056 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 9 March 1973 [17 March 1972] 11407/73 Heading H4K A safety device for controlling access from devices, in duplicate control chains each including a computer, to a common controlled or interrogated equipment characterized in that for each pair of duplicate items there is a pair of oscillators synchronized in phase opposition, each oscillator controlling a corresponding gate gating connection requests to corresponding bi-stable circuits, each bi-stable circuit when set inhibiting the other gate. The Figure shows a telephone system controlled by duplicate chains including processors 1a, 1b and peripheral devices only one duplicate pair 2a and 2b of which are shown. Each processor instructs its peripherals via interfaces such as 16a, 16b. When an interface receives an instruction to connect that peripheral to a common equipment it sets a seizure bi-stable 7a or 7b. If the common equipment is not in use operation bistables 8a and 8b are reset at this time and apply via inverters 21a and 21b enabling inputs to AND gates 11a and 11b. A pair of oscillators 10a and 10b synchronized in phase opposition alternately enable a third input to each AND gate so that if the corresponding siezure bistable 7a or 7b is set the operation bi-stable 8a or 8b is triggered to the 1 state. Setting of a bistable 8a or 8b seizes the common equipment via a timing circuit and inhibits via inverter 21b or 21a seizure by the other peripheral of the pair. After a predetermined time timer 9a or 9b resets the associated bi-stables 7a, 8a or 7b, 8b allowing the other peripheral to seize the common equipment. Relays 12a and 12b are slow to release, are normally maintained by a constant stream of pulses from the associated computer and have contacts 12a1, 12a2, 12b1, 12b2 in the inhibit paths between the peripherals. In the event of a failure of one processor or the detection of a fault in a peripheral, one relay is released preventing the associated peripheral from inhibiting operation of the other peripheral. In a second embodiment not detailed blocks identical to 5a and 5b are contained within the processors and control access between the processors and a switching network, path search or trunk selecting arrangement.

Abstract: 539,131. Rope drums. STURM, E. July 10, 1940, No. 11495. Convention date, Nov. 17, 1938. [Class 78 (v)] A regulable hydraulic variable power transmission gear for a rope drum 1 is mounted within the drum, the control means therefor being likewise arranged within the drum and being operable from outside. The rotary pump member is located at the left-hand side of an annular partition 10 dividing the drum into two internal chambers, and is mounted on a hollow shaft 11 adapted to be connected to an external power source. On the shaft 11 is a casing 14, 15, 16 adjustable eccentrically relative thereto by a pin 21 on a frame 19 carrying the casing 14, 15, 16 and mounted in guides, the pin 21 engaging a cam slot in a segment 25 fixed on a spindle 24 fitted with an external hand-wheel. The output of the pump is determined by the relative positions of the vanes 27 and their enclosing casing 14, 15, 16, as controlled by the hand-wheel. The hydraulic motor is similarly constructed and is disposed co-axially with the pump in the right-hand chamber, the control being by a cam sector on the spindle 24 for simultaneous actuation with the pump. The operating fluid is contained in a reservoir 34 in a lateral compartment which contains gear wheels, the reservoir 34 communicating with the pump and motor by ducts 36 leading through a stationary spindle 29 located in the pump and motor hollow shafts. A piston 42 pressed upon by a spring 45 carries a ball socket which adjusts the position of a pivoted lever 38, 39 bearing against a stop 40 on the motor casing, which limits the minimum admissible eccentricity of the motor. The increased pressure of the fluid at the start moves the piston 42 and with it the eccentricity of the motor casing beyond normal, thus giving a high starting torque. The spindle 24 may carry a pinion meshing with a toothed ring supported in the gear casing and acting on the frame through a cam and pin. The drum is enclosed by a shell 3 having a slot through which the cable emerges. The gear casing 7 slides in a collar 8 at one end to allow for heat expansion.
