    Abstract: A LEAK TESTING DEVICE, COMMONLY EMPLOYED IN TESTING AUTOMOTIVE ENGINE COMPONENTS AND THE LIKE, WHICH PRESSURIZES THE PART TO BE TESTED AND A STANDARD CHAMBER, SEPARATES THE TWO, AND THEN MEASURES THE DIFFERENCE IN PRESSURE OVER A GIVEN PERIOD OF TIME BETWEEN THE PART AND THE STANDARD CHAMBER. THE IMPROVEMENT IN SUCH A DEVICE REDUCING THE TIME REQUIRED FOR TAKING A REPRODUCEABLE USEFUL READING BY INCORPORATING BAFFLES IN THE STANDARD CHAMBER WHICH RESTRICT THE FLOW OF TESTING FLUID THEREBY REDUCING OSCILLATION AND HASTENING STANDARD CONDITIONS, THE BAFFLES ARE PREFERABLY IN THE FORM OF PLATES OR DISCS SPACED LONGITUDINALLY

    OF THE BALLAST CHAMBER WITH EACH HAVING A SPACE BETWEEN ITS OUTER PERIPHERY AND THE WALL OF THE CHAMBER, OR FORMED WITH PERFORATIONS THEREIN, OR A COMBINATION OF BOTH.

    Abstract: 1,109,251. Moving band filter. AJEM LABORATORIES INC. 13 April, 1965 [16 April, 1964], No. 15834/65. Heading B1D. A travelling band filter comprises a filter web 26 entrained round a rotary drum 20 in a tank of unfiltered liquid, the drum and web being carried by a frame 68, pivoted at 70 so that it may be lifted out of the liquid, the interior of the drum communicating witha filtrate suction pump 52 through a seal comprising flanges 72, which are urged together by the weight of the frame and drum alone. In Fig. 1, the web 26 is disposable, fed from roll 28 round roll 30, drum 20, roll 62 and up ramp 34. Scrapers 38 engage the medium and solids fall to the bottom of the tank and are removed by endless scraper conveyor 40. The two chains of conveyor 40 are driven by a motor 64 and engage peripheral teeth on drum 20. Rolls 30, 62 are driven off the drum and so are the chains 37 of a second endless conveyor which lifts the used web up ramp 34. The interior of drum 20 above the liquid level is closed by arcuate baffle 74. In Figs. 2 to 11 (not shown), an endless filter band is cleaned by reverse flow gas from fixed nozzle (112) and is held against the drum by the bars linking the two chains of an endless conveyor which rotates the drum. Filter cake breaks from the band where it passes over upper roll 120. movable to adjust tension. An external double ramp sealingly engages the upper part of the drum and guides the band on and off the drum. The filter web may be of nylon or glass fibre and may drive the drum directly, without any conveyor being used. A nylon cloth web may have pockets therein containing reinforcing cross members.

    Abstract: 1,153,433. Endless conveyers. AJEM LABORATORIES Inc. 24 June, 1966 [8 July, 1965], No. 28546/66. Heading B8A. [Also in Division B1] An endless conveyer belt 10 is formed with guide rails 13 which are adapted to engage guide pulleys 15b, 15c, 15d thereby constraining the belt to a pre-determined path. The rails 13 are mounted on edging strips 14. The pulleys may be adjusted in a direction normal to the plane of the belt by screws (19), (Fig. 2, not shown); they may also be resiliently mounted. The rails may be of triangular, square, trapezoidal or half-round cross-section, the crosssection of the pulley rim conforming to this shape in each case. As applied to a mesh screen belt for a filtration unit (Fig. 8, not shown), (see Division B1) one guide pulley (72) is located near a drive drum (71) which bears the reaction of the pulleys (72). Another pulley (74) bears on a bearing surface (76).

    Abstract: 1,047,705. Gas washers. AJEM LABORATORIES, Inc. June 4, 1963 [June 4, 1962], No. 22184/63. Heading B1R. A gas washer of the type having a rotating spray generator in the form of a cage 30 has a hollow frusto-conical pump body 34 secured to a ring 33 at the base of the cage, at least the lower end of the body 34 dipping into washing liquid in the base of the washer housing. The connection between the pump body and the cage may be substantially fluid-tight and the body may be cylindrical or bowl-shaped. Impeller vanes may be arranged on the internal surface of the pump body and in some modification (Figs. 4 and 5 not shown) stationary vanes are provided on a rod extending upwardly from the base of the washer housing into the mouth of the pump body.
