摘要： A method and apparatus are disclosed for degassing the pressure fluid of a hydraulic system, in which a vacuum is maintained in the free space above the pressure fluid in the fluid reservoir of the hydraulic system by a vacuum pump. The vacuum pump has a selective pumping action, by virtue of which permanent gases present in the free space are withdrawn but vapors of the pressure fluid present in the free space are not withdrawn. Pressure fluid entering the reservoir from the hydraulic system is passed over a degassing surface to promote separation of the permanent gases in the pressure fluid from the fluid. A compensating line is provided between the vacuum pump and the reservoir for returning to the reservoir the nominal amounts of pressure fluid withdrawn from the reservoir by the pump. Valves provided in all fluid lines leading to and from the reservoir maintain the vacuum in the reservoir during system shut-downs.

摘要： 1279592 Wheel trims H BUERGER 27 May 1970 25434/70 Heading B7C A wheel trim 12, Fig. 1, is mounted on a wheel rim 11 and has a grip ring 30 attached to a wheel trim member 31, the ring 30 having on one side axially and radially extending alternating longer and shorter spring lips 60 and 61 respectively which grip a shoulder 19 of the rim flange 16 and on the other side tabs 45a which grip a radially extending flange 33 of the trim member 31. The spring lips 60 are more flexible than the spring lips 61. The ring 30 is made from a flat die-cut blank 40, Fig. 3, which has a central elongated portion 41 having a purality of equally spaced holes 42. Along one longitudinal side, the blank 40 has equally spaced transverse slots 44 forming tabs 45 having edges 46 in longitudinal alignment, the edges of the tabs 45 being bent at right angles to the portion 41 to form tabs 45a. Along the opposite longitudinal side to the tabs 45, the blank 40 has alternating longer and shorter tabs 50, 51 respectively, spaced by notches 52 aligned with alternate slots 44. The blank is shaped to form the ring 30 by welding its ends together and tabs 50, 51 are bent to form the spring lips 60, 61 respectively.
