摘要： The shutter is designed to have a favourable dynamic shape by the use of a plane parallel plate with a pear shaped edge, the geometry of the surface being of pure shape. The plate can be shaped to have a convex profile either upwards or downwards, or alternatively in both directions. It is placed in the optimum position by a rotary or a swivelling motion. Typically when a graph is drawn up in which the lift (in mm) is plotted against the ratio of vol/time, at all values of lift up to approx. 250 mm the vol/time ratio for the aerodynamic design in increasingly greater than for that of a conventional design.

摘要： The leak sealing-pad for sealing off the damaged wall of containers and pipes is constructed from reinforced rubber material which is vulcanized under heat. It has a pad-surface (20) which is faced towards the leak and a pad-surface, equally as large, which faces away from the leak (22), both these surfaces being joined at their edges to form an air-tight inner-chamber (24) which can be accessed externally via a nipple (26). Attachment components (30), loops 54, and bridges 64 are attached to two edge zones which lie opposite each other, the narrow sides 28. These attachments are intended for a tension device which spans the container or pipe. Both the surfaces of the pad (20, 22) have internal reinforcing with bisecting, flexible reinforcing threads (34, 36; 40, 42). The pad-surface which faces toward the leak (20) is reinforced solely with reinforcing threads (34, 36) applied diagonally to the rectangular sides (28, 38) of the pad, while the pad-surface which faces away from the leak (22) has reinforcing threads (40, 42) which run parallel to the rectangular sides (28, 38).

摘要： A rectangular pneumatic lifting pad of the type made from hot-vulcanized, web-like and not previously vulcanized rubber material and having an inside airtight bladder comprised of a first reinforced layer of flat rubber material and a similar second reinforced layer, said first and second reinforced layers having their respective reinforcing strands running parallel to a first edge of the rectangle and to the second edge perpendicular thereto, respectively, CHARACTERIZED IN THAT the first reinforced layer comprises first and second blanks, the first blank being folded transversely to the direction of reinforcing strands to have both edges of its folded sides preferably just touching, and the second blank being disposed underneath and being substantially coextensive with the two folded sides of the first blank without extending fully between said first edge of the rectangle and its parallel, opposite edge; and the second reinforced layer comprises third and fourth blanks that are similarly constructed, configured and disposed as said first and second blanks but in relation to said second edge of the rectangle.

摘要： A pneumatic flat pad is provided herein. It includes two opposed covers of flexible material which are spaced apart from each other and which are joined at their margins by a marginal joint so that the two covers and lateral marginal joint cooperate to form between them a hermetically sealed hollow space. A plurality of cord inserts æ e embedded within the covers, each of said covers being reinforced by at least one embedded cord insert. An attachment is provided for connecting the hollow space to a source of compressed air. At least one of the cord inserts of one of the covers is embedded within, and extends through the lateral marginal joint of the pad to the other cover is which it is also embedded and within which it overlaps a portion but less than all of that cord insert of the other cover. In this way, the lateral marginal interconnecting edges are reinforced so that the lifting cushion so provided is much stronger and safer in use.
