    摘要： Portable apparatus for delineating a playing area including a plurality of elongate members of appropriate length for defining sides of the area. One pair of the members are channels which have ends cut to the form of blunted arrowheads. Another pair of the members, referred to as side members, have apertures extending therethrough adjacent their ends adapted to receive the arrowhead ends of the channels therethrough with the diverging lugs on the ends of the channels releasably locking the channels to the side members in desired angular relationship. One of the side members has an enlarged coupling head extending therealong and the other side member has a coupling groove extending therealong adapted frictionally to receive and hold a coupling head therein. Adjacent frames formed by the interconnection of the members may be releasably connected to each other by insertion of a coupling head on a side member of one frame into the coupling groove of a side member on another frame. The members are initially formed as an extrusion with the members interconnected in the extrusion through bendable connectors whereby they may be folded over each other, with the coupling head of one of the side members received in the coupling groove on another of the side members, to provide a compact package for storing and transport.

    摘要： A portable projection screen including a sheet of flexible material and a collapsible support for the sheet. The support includes a central hub member having a plurality of sockets therein. Multiple extensible-contractible rods fit at one set of their ends in the hub member and radiate outwardly therefrom. The outer ends of the rods are received in connectors secured to edge margins of the sheet, and when the rods are extended they tense the sheet into a substantially planar surface. A collapsible mast is provided for supporting the screen above a horizontal surface, or for hanging it on a wall.

    摘要： Superalloy articles are made more oxidation resistant by a process which includes heating the article in an environment having a reduced pressure of inert gas and a low partial pressure of oxygen to a temperature at which the sulfur in the article diffuses out. The heat treatment is best carried out at a temperature within the range defined by the incipient melting temperature of the article and about 150.degree. C. below the incipient melting temperature of the article. Alternatively, the heat treatment may be carried out at a temperature above the gamma prime solvus temperature of the article and below the incipient melting temperature of the article. At such temperatures, sulfur readily diffuses out of the article, and a more oxidation resistant component is produced.
