Title: Device for aerating water such as waste water
IPC: C02F3/20
Filed: 1965-07-13
Abstract: A device for aerating, e.g. waste water, comprises one or more blocks of soft cellular porous plastics having one or more cylindrical recesses there within into which compressed air is fed.  When the air supply is interrupted, the block contracts and subsequently expands when air is supplied again, this action preventing clogging of the pores.  The block or blocks are clamped between end plates interconnected by tie-rods and the air supply is fed into one endplate.

IPC: H01G13/00
Filed: 1960-08-31
Abstract: 893,310. Capacitors. TELEGRAPH CONDENSER CO. Ltd. (Sprague Electric Co.). Aug. 31, 1960, No. 29999/60. Class 37. A capacitor element 12 (Fig. 1) is housed in a metal, e.g. aluminium can 10 lined with, e.g., paper 14 (which may be omitted) and a resilient tab 20 connected to one foil is welded to the inner surface of the can end to whose outer end surface is also welded an external lead 24; the capacitor element being wound on a metal, e.g. aluminium, riser 16 connected to the other foil and extending outwardly of the can through a rubber bush 30 over which the open end of the can is rolled to effect a seal; a further external lead 38 being welded to the riser. The capacitor element may be electrolytic. In manufacture the riser of the capacitor element is clamped in a spot-welding electrode 41 (Fig. 2) and an opposed electrode 42 supports in block 44 the lead 38 having (Fig. 4, not shown) a ball end surrounded by an annular conical collar to assist in welding the opposed lead and riser. Thereafter the grummet 30 is placed over the lead and riser, and tab 20 is inserted into can 10 inverted over upstanding tungsten tipped anvil 64 of welding electrode 62 (Fig. 3), while electrode 61 carries lead 24 whose end has similar configuration to lead 38. The lead and the tab are simultaneously welded internally and externally of the can and element 12 may then be inserted therein with folding of the tab; the can being rolled and crimped over the bush 30 for sealing. The capacitor element may be impregnated before insertion in the can; or the whole assembly may be vacuum-impregnated thereafter. The tab and riser may be crimped, staked, or spot-welded to the capacitor foils, lead 38 may be omitted using the riser as a terminal connection, and lead 24 may be crimped into a socket formed within the closed end of the can, which may be of steel or brass for non-electrolytic capacitors, or aluminium, tantalum, or silver for electrolytic capacitors. It may also be formed of plural inter-fitting metal laminations welded together simultaneously with the welding of the tab and external lead.

Abstract: 191,536. Dine, J., and Rigby, J. W. Nov. 11, 1921. Fermenting.-Air and gas escaping from a fermenting vat are led into a perforated pipe extending along the bottom of a vessel containing liquid to trap any entrained spirit. A number of vats a may be connected by conical collectors to a pipe c terminating in an inverted U-tube f which passes down to the bottom of a closed vessel e and is continued as a perforated pipe h. The gas escapes from the vessel e by a vent m the orifice of which is enclosed by a baffle n dipping into the liquid. If open vats are employed, the gases are drawn off and forced into the vessel e by a pump, non-return flap-valves being interposed between the vats and collectors.

Abstract: 385,064. Magnetically-actuated valves. BARRALET, J. H. and NEW GEYSERS (1931), Ltd., 25, Addington Square, London. July 29, 1932, No. 30161/31. [Class 135.] The gas valve of a geyser is opened by the flow of water to the geyser acting through a pair of co-operating permanent magnets moving in unison. The gas and water chambers 1, 4 are separated by a thin partition 7 of stainless steel reinforced by a brass plate 8 having segmental slots 9. The plate 8 has central projections in each chamber on which are pivoted permanent magnets 15, 16 ; the poles of the magnet 15 working in the slots 9. One limb of the magnet 16 is fitted with a weight 17 causing it to tilt into close proximity with the end of a spindle 26. This spindle which is fitted with a weight 29 is guided in the water inlet chamber by spiders 27, 28 and is fitted with a flexible washer 24 held between plates 25. The washer nearly fits the chamber so that when water is flowing the spindle is lifted to tilt the permanent magnet 16. As the magnet 16 is tilted, the magnet 15 follows it to bring one limb into contact with the lower end of the gas valve and open the valve. The gas valve has a spherical face and is guided by the spindle working in spiders 21, 23.

Abstract: 713,869. Electric cooker. EAST MIDLANDS ELECTRICITY BOARD, and CARTER, F. T. Dec. 22, 1952 [Dec. 27, 1951], No. 30205/51. Class 39 (3) In an electric cooker comprising an outer case and an inner oven case removable as a whole or in sections, a unitary structure carrying the heating elements 8 and their associated connections is readily movable as a whole in and out of the oven door opening to stand in position in the outer case in heating position without the use of bolts or the like, the inner oven case being then replaced. The unitary structure comprises two vertical sides E each carrying wire heating elements 8 and hinged at their lower ends 12, 15 to a base frame A of slightly longer length than the width of the inner oven, the base frame also carrying a heating resistance. The hinges 15 of one side frame E are at points offset with respect to the median lines of the bars of the sides of that frame so that it may be folded down on the base frame A; and the lower end of the other side frame is secured to arms 13 pivoted at 12 to the base frame so that it can be folded down on the first side frame. Each side frame may carry arms 13, which are longer on one side frame than on the other. Each side frame and the base frame comprises two parallel steel bars 1 spaced by cross rods on which are threaded small ceramic formers 3 supporting coiled resistance wire 8 connected to terminals 7. Collars 9 on the cross rods insulate the terminals 7 from a bar 6 on which they are mounted. Each bank of formers is covered at the rear by an asbestos sheet 10 with an outer sheet metal cover 11. The hinge bolts 15 pass through holes in the top of the base frame 1 and at the inner edge of the vertical side frame bar 16, so that the side frame can fold flat on the base frame. The resistances may be connected directly to the cooker switch through cleats, or leads therefrom may pass through holes in the outer case to terminals in the side of the outer case. When the inner oven case is loose, it may rest when replaced on a pair of detachable angular runner arms adjacent the lower corners of the outer case, and when these runner arms are inserted they may clamp down the base of the inserted cradle. The resistances may be connected in series or parallel and the connections help to hold the cradle in position. The hinge may comprise slots 17 in the bars 1, in which slide bolts 12 attached to the links 13, to make the space between the side frames adjustable. Each frame may carry two banks of resistances each on a single piece ceramic former.
