Title: Fixture and system for treating test pieces on a rapid cycle leak detection apparatus
IPC: G01M3/20
Filed: 1972-06-21
Abstract: 1397464 Leak testing VARIAN ASSOCIATES 21 June 1972 [2 July 1971] 29067/72 Heading G1S A beer can top 10 is tested for leakage by applying a tracer gas such as helium and then compressed air to one side 41 of it, and connecting a mass spectrometer to the other 42. In use, a top 10 is placed on a supporting structure which includes a support ring 32, a sealing ring 37, and support members 30 and 31, the supporting structure being mounted on the housing of a valve 13 which connects the underside of the top 10 to the mass spectrometer when plunger 85 moves into the housing. A lever 8 is then moved downwardly by the operator to clamp a cover plate 24 over the top 10 and to move the spool 57 of spool valve 50 from a position in which chamber 41 above the top 10 is connected to vent 56 to a position in which it is connected to line 62 and filled with helium from source 65 via shuttle valve 63. The lever 92 is then actuated by the operator which causes timer 92 to operate a valve 89 so that compressed air is applied to the right and then the left of piston 84 for first and second periods respectively. In the first period, piston 84 moves to the left to operate valve 13 to connect the underside of the top 10 to the mass spectrometer. In the initial part of the stroke of piston 84, the spool 73 of a spool valve 67 is held in the open position by disc 86 and lever 79 so that compressed air may pass through spool valve 67 to shuttle valve 63, and from there to the chamber 41 via line 62 and spool valve 50. The high pressure of the compressed air moves the ball 68 of the shuttle valve from the position shown to one in which it blocks the port 69 so that compressed air does not enter supply 65. After a short initial movement of piston 84, before opening of valve 13 has been effected, spool valve 67 closes so that in the event of rupture of the top 10, there is no connection between the compressed air supply and the mass spectrometer. In the second period, the piston 84 is moved to the right. The operator then operates lever 8 to free the top 10. As shown in Fig. 1, two test fixtures may be provided so that while the test is being carried out in one fixture, the other may be unloaded and reloaded with the tops 10. The lever 92 serves to initiate the test on either fixture.

Abstract: 654,133. Agglomerating finely divided materials. BRASSERT & CO., H. A. Nov. 15, 1948, No. 29654. [Class 82(i)] A method of forming nodules of finelydivided materials, such as metal ores, consists in mixing the material with a liquid, such as water, to form a plastic mass, allowing the mass to extrude through one or more openings in a substantially horizontal supporting plate or screen, and agitating the supporting plate or screen to break into predetermined lengths the material protruding from the underside of the plate or screen. Fig. 1 shows a screen 18 to the edges of which are welded angle lugs 15. The lugs rest on angle irons 12 and are retained thereon by bolts 13 passing through elongated slots 14 in such a manner as to allow the screen to be vibrated horizontally or substantially horizontally by electric or pneumatic vibrator 21. Fig. 4 shows the screen box 17<SP>1</SP> mounted in the upper end of an inclined rotary drum 24. Nodules from the screen fall on to cone 23' which discharges them on to the drum in which by rolling they assume a substantially spherical form. The drum is heated by burners 28 and 29 to dry its interior and to prevent adhesion of nodules to its walls. The nodules may then be heated, for example, to between about 900‹C and 1250‹C to drive off the plasticizing liquid and leave them in a strong porous form.
