Title: Pressure booster for compressed air line - has double acting piston driven by supply air with reversing valves
Inventor: GALI MALLOFRE SALVADOR
IPC: F04B9/133
Filed: 1976-12-10
Abstract: Compressed air entering from the line is directed by a changeover valve to one of two inlet valves each of which leads to a driving chamber. From this the air goes to a compression chamber. A double acting piston has a wider section with one face in each of the driving chambers. Air admitted to a driving chamber forces the piston down and its narrow end compresses the air in the opposite compression chamber. The driving air then flows into its compression chamber, the piston reverses the valve at the end of its stroke and the process is repeated in the other pair of chambers. The booster can raise the pressure at the end of a line without external means.

Title: Wheel rim for pneumatic tyre - has separate flange rings firmly held by prestressed sealing ring when tyre is not pressurised
Inventor: SCHUERMANN HEINRICH
IPC: B60B25/22
Filed: 1977-08-18
Abstract: A vehicle wheel with a pneumatic tyre has a ring at each side of the true trim, the flange being part of the ring. The rim and ring are sealed together by a rubber ring located in a groove of the rim and a groove of the ring. This rubber ring is prestressed before the tyre is inflated and prevents any axial displacement between the ring and the rim. Pref. the ring is initially offset towards the centre of the wheel, the rubber ring lying with virtually no prestress in a groove of the rim. By pushing the ring axially outwards, the rubber ring is rolled up a slope causing its dia. to increase and thus prestressing it, until it comes to rest in a groove of the rim, a corresp. groove of the ring simultaneously coming to rest over the rubber ring. Even when the tyre is not pressurised, the ring is firmly located relative to the wheel rim.
