Filed: 1946-11-04
Abstract: 617,756. Batteries. BURGESS BATTERY CO. Nov. 4, 1946, No. 32741. Convention date, Nov. 14, 1945. [Class 53] A dry cell has an insulating sheath 32 surrounding the zinc cup electrode 10 against which it is pressed firmly by metal rings 34, 35, surrounding the upper and lower ends of the sheath. The lower end 37 of ring 35 grips a pad 38 which is provided to absorb any electrolyte exuding between the lower end of the sheath 32 and the bottom of the cup 10. The upper end of the cell is made liquidtight by washers 27, 30 made of paraffin impregnated paper enclosing an absorbent washer 29 of blotting paper. Above the washer 30 is a layer 31 of soft sealing composition. The flange 41 of the upper ring 34 is gripped between washers 42, 43, which also press the upper end of the sheath 32 into contact with the sealing composition 31. The carbon rod 19 is fitted with a metal cap 21 which is shaped to form a groove to receive the washers 42, 43. Liquid formed during the operation of the cell is accommodated in the space 28 and may be forced past the edge of the washer 27 and be absorbed in the washer 29. Excess liquid and gas may pass from the washer 29 through an aperture 47 in the cup 10 and into a groove 48 between the cup and the sheath 32. Liquid leaking by the washer 30 and seal 31 is received in the space 46. The sheath 32 may consist of one or several layers of chlorinated rubber, cellulose nitrate, polyvinyl chloride or other insulating extensible material which may be shrunk by heat on to the cup 10. The depolarizer 25 of manganese dioxide and graphite moistened with electrolyte is surrounded by blotting paper, gelatinized starch, &c. 26 moistened with a solution of ammonium and zinc chlorides. Fig. 5 shows a modification in which the cell is closed by a washer 59, sealing composition 61, and an insulating cover 68 which carries a metal contact plate 73 riveted to the metal cap 71 on the carbon electrode. To relieve excessive internal pressure the zinc cup is provided with a thin spot in its side wall which becomes perforated and allows liquid to flow into the space between the cup and the outer sheath which may be made in two layers the inner one of which is absorbent. A groove may be provided in the outer surface of the top flange 86 of the zinc cup to lead any liquid or gas escaping by the seal 61 into the space between the cup and sheath.

Abstract: 1,249,103. Sampling and dispensing apparatus. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 7 Oct., 1968 [19 July, 1967], No. 33179/67. Heading B1X. In a sampling and dispensing apparatus manipulation of piston 5 causes diluent or reagent liquid to be withdrawn through non- return valve 8 and dispensed through non- return valve 10 until the liquid just fills tubes 1 to the horizontal orifices 28. By raising piston 15 a volume of liquid is withdrawn from tubes 1 and simultaneously a volume of sample solution is drawn by suction into tubes 2, the orifices 27 of which are immersed in the sample solution, from where these sample volumes may be dispensed by lowering piston 15 until tubes 1 are again refilled with diluent liquid. During the lowering of piston 15, piston 5 is also lowered so as to cause liquid to overflow each of tubes 1 and be dispensed through tubes 2, although sample solution is always dispensed prior to this overspill of liquid from tubes 1. From the volumes swept out by the pistons in cylinders 13 and 16 the volume of liquid diluent used to wash out tubes 2 can be calculated and calibration marks 30 on tubes 2 enable the volume of sample dispensed to be known. On completion of the dispensing operation, a valve 26 of inlet 29 is opened to admit air under pressure and flush out any residual liquid remaining in tubes 2 or on the surfaces of tubes 1 or vessel 3. The flow rate of liquid in the system is controlled by capillaries 14.

A lap winding machine in which laps are wound on a tubular core containing a lap rod is provided with a lap rod magazine located above the position into which a completed lap is withdrawn from the core and so arranged that the motions involved in the extraction of the core cause one of the rods to drop into a position from which it can enter the core during the build-up of the next lap. During doffing, the lap 3 enters a trough 5 that is then moved to the left in the figure to remove the lap from the core 4. An abutment 7 connected to the trough enters a slot in a ledge 8 of the rod magazine as the trough 5 nears the end of its movement. The lowest rod 1 in the magazine is thereby moved until its disc 9 and shaft are over slots through which it falls to the broken line position. Meanwhile a fresh lap begins to be wound and, as the core 4 reaches a predetermined height during the winding, a lever 14 is tripped to actuate a switch 15 resulting in the return of the trough 5 to its original position and the insertion of the rod 1 in the core 4.
