Abstract: An improved method of forming a filamentary reinforced article includes forming a preform of metal and filament layers by winding material around an axis. The resulting layered preform is enclosed in a fluid tight housing. The housing has a rigid frame which bounds the periphery of the preform. The housing also has flexible panel sections which extend inwardly from the frame across the preform. To bond the layers of the preform together and increase the density of the preform, the housing is subjected to a hot isostatic pressing operation. During the hot isostatic pressing operation, fluid pressure forces against the housing plastically deform the panel sections of the housing inwardly in a direction parallel to the axis around which the layers of the preform were wound to apply axial deformation forces to opposite sides of the preform.

Since the bracket is installed near the crease of the stair, it should reduce any downward slipping of the carpet also.

Abstract: A reusable device for connecting hose or tubing to a hole in the panel of machines, vacuum motors, and the like, that can be installed and removed by hand. Installation requires no special skill, tools, or panel preparation, and does not alter the panel in any way. Once installed, hose or tubing can be clamped onto the device by a conventional way. The device consists of three interlocking parts assembled in the order in which they are presented in FIG. 1. Part A is a flexible tubular body with a flange (11) at one end and a slotted section (17) along its length. When the body is squeezed together the diameter of the flange (11) is reduced, allowing it to pass through the hole in the panel. Once inserted into the hole, and the pressure released, the diameter of the flange (11) expands. The flange, once again larger than the diameter of the hole, secures the tubular body in the panel. Part B is an insert that fits into the slotted section (17) of Part A and completes the tubular shape of Part A.
