IPC: B60C17/10
Filed: 1971-12-22
Abstract: 1419069 Pneumatic tyre and wheel assemblies DUNLOP Ltd 13 Dec 1972 [22 Dec 1971] 59776/71 Addition to 1359461 Heading B7C In a pneumatic tyre and wheel assembly comprising an enclosing means, e.g. 13, for a lubricant such that, in use, the lubricant is automatically released from the enclosing means upon deflation of the tyre to lubricate the interior surfaces of the tyre and facilitate continued running of the assembly, a balance weight 16 is provided whereby, in use, the mass of the enclosing means and lubricant is counterbalanced when the lubricant is in the enclosing means but on release of the lubricant the assembly becomes out of balance to indicate to the driver of the vehicle on which the assembly is mounted that the tyre is deflated. The enclosing means may have a frangible projection 14 or diaphragm rupturable by the deflated tyre to release the lubricant, or alternatively may be provided with a valve responsive to a decrease in pressure below a predetermined level within the inflation chamber of the assembly to release the lubricant. The rim of the wheel may have a well, and in this case the enclosing means may consist of one, as shown, or more arcuate containers 13 within the well occupying an arc of the well base less than <SP>1</SP>/ 3  of the total circumference of the well base. The arcuate container or containers may be formed integrally with the well and provided with replaceable lubricant release means, or may be detachably secured in the well. The or each arcuate container may project radially outwardly beyond the well to prevent tyre bead displacement into the well. Diametrically opposite the container 13 or containers there may be a tongue 20 fixed to a tyre inflation valve rotatably mounted in the well wall so that the tongue can be pivoted from the full line position in Fig. 1 where it prevents displacement of the outboard tyre bead into the well to the dotted line position in Fig. 1 in which mounting or removal of the tyre is permitted. Further such tongues 20 may be provided for the outboard and inboard beads, these tongues being fixed on bolts rotatable in the well wall. The wheel rim may alternatively be formed without a well. Specifications 1,359,462; 1,359,463; 1,359,464; 1,359,465; 1,359,467 and 26695/75 are referred to.

Abstract: 1,262,920. Detecting leaks in packages. NORTH AMERICAN ROCKWELL CORP. Dec.17, 1969 (Dec.23, 1968], No.61551/69. Heading G1S. A method of inspecting a sealed ionizing gascontaining package for a leak comprises placing the package 66 in a chamber 28, closing the chamber passing an inert gas through the chamber from an inlet 42 to an outlet 46 and analysing the gas leaving the outlet 46 after a predetermined time for the presence of the ionizing gas in the packet. As described apparatus 10 comprises inspection block 12 in two separable parts 14, 16, having an inner chamber 28 and a surrounding outer chamber 30 in which is a sealing gasket 32. A helium gas source 34 is connected via valve 36, lines 38, 52 to a gas chromatographic nitrogen detector 54, and via valve 37 and line 40 to inlets 42, 44 to the inner and outer chambers respectively of the inspection fixture 12. Outlet 46 from the inner chamber 28 is connected via lines 50, 51, 52 and valve 48 to the detector 54 and from valve 48 through line 58 to discharge line 60. Outer chamber 30 is connected via line 62 to discharge line 60. The mating faces of the separable parts 14, 16 of the inspection fixture 12 are in sealing engagement. In use, after the packet 66 is placed in the inner chamber 28 and the chambers closed, helium is passed through the detector to provide a steady baseline on chart 56. Helium is then passed through the inner and outer chambers 28, 30 to sweep out air. Valves 36, 48 are then altered to pass helium from the chamber 28 to the detector where nitrogen (from residual air) produces a large peak (70) Fig.2 (not shown) on chart 56. If nitrogen from leaks is present the peaks have different forms (74, 76).
