Abstract: ABSTRACT OF THE DISCLOSURE           A sign has a rigid peripheral frame extending around an opening lying in a plane, and a sheet of flexible sign material extends across the opening.  The frame has an edge surrounding the opening, and the flexible sign material has a peripheral edge portion extending over the edge and rearwardly from the plane of the opening.  A series of separate sheet tensioning devices is spaced around the frame rearwardly of the plane of the opening, each tensioning device comprising means for retaining the peripheral edge portion of the flexible sign material and means for adjust-ing the position of the retaining means relatively to the frame to cause the peripheral edge portion of the flexible sign material to be pulled rearwardly across the frame edge to tension the flexible sign material across the opening.          Each retaining means includes a first member having a recess extending longitudinally of and facing the frame edge, the recess being open at at least one end of the first member, and a second member having a first part engageable by the adjusting means and a second part insertable into the recess in the first member by relative longitudinal movement into an open end thereof.  The recess of the first member and the second part of the second member are shaped to cause the first member to prevent movement of the second part of the second member out of the recess in a forward direction, and the peripheral edge portion of the flexible sign material is wrapped around the second part of the second member in the recess and thereby retained by the tensioning device.

Abstract: A B S T R A C T      A pipe coupling having an annular gasket deformed and compressed within a closed gasket chamber to form a seal for a pressurized hydraulic line, for example, one wall of the gasket chamber being formed by the outer surface of a pipe end portion which is to be connected either to a second pipe end portion or to a wall port.  The axial width of the gasket chamber is determined by an abutment of the end face of the pipe end portion which transmits the abutment force to a threaded clamping sleeve or, as the case may be, to a coup-ling nut with the aid of a snap ring which engages a periph-eral groove of the pipe end portion and a thrust shoulder of the threaded clamping sleeve.  The pipe-to-pipe version of the coupling has two annular gaskets inside identical gasket chambers on opposite axial sides of a centering sleeve which surrounds both pipe end portions.

Abstract: ABSTRACT.            A  method for growing an oxide layer on a silicon surface.     In an improved method for thermally growing an oxide layer on a silicon surface of a semiconductor body a first oxide layer portion is grown over the silicon surface in a first thermal oxidation process at a temperature of less than about 1000°C. The semiconductor device is then annealed in a nonoxidizing ambient at a temperature above about 1000°C, and finally a second oxide layer portion is then grown over the first oxide layer portion in a second thermal oxidation process to complete the growth of the oxide layer. The silicon surface may be of either polycrystalline or monocrystalline material. This method avoids both the dopant outdiffusion problems associated with present High-tem-perature oxidation processes and the stress-related irregularities associated with known low-temperature oxidation processes.
