Abstract: A thermally insulative buoyant swimming pool cover floats on the surface of the pool for covering the pool and for retaining the heat within the pool. Sinking means, such as weights or a mechanical pull-down structure, is secured to the pool cover along certain predetermined action lines such as fold lines. In one embodiment, an inflatable and deflatable bladder is coupled to the weights. The bladder is dimensioned relative to the weights such that when inflated it overcomes the negative buoyancy of the weights to retain the pool cover in the fully covered position. However, when the bladder is deflated, the weights overcome the positive buoyancy of the cover along the certain fold lines causing the cover to be at least partially pulled below the surface of the pool and folded while at the same time being retracted against one of the side walls of the pool. Pool water is circulated over or through channels of the pool cover to provide solar heating.

Abstract: An attachment for the spout of a sink fixture permits the stream of mixed hot and cold water to be readily turned all the way on and off, by simple flipping of a snap-action lever control, without it being necessary to adjust the hot or cold faucets. The flipping is non-critical and does not require any fiddling. The desired temperature and rate of flow are maintained, after having been initially achieved, during subsequent turnings on and off of the stream. The attachment is designed to be screwed into place between the spout and its matching non-splash aereator, normally screwed directly to the spout.

Abstract: A solar collector panel consists of a metal sheet and a number of straight metal tubes intimately connected to the sheet in order to obtain maximum thermal conductivity. One tube each is connected to a sheet by slotting the latter along a straight line by equidistant parallel short cuts and pressing the areas between two consecutive cuts into semi-cylindrical bulges alternately in opposite direction from the sheet surface. These bulges have a concave semi-circular cross section of a diameter slightly larger than the outer diameter of the tube, and all bulges along the straight line form a continuous passage into which the tube is inserted. After insertion the tube is expanded by mechanical means or by hydraulic pressure and pressed onto the semi-cylindrical portions of the sheet, satisfactory contact being obtained by dimensioning the expanding pressure to a magnitude that the tube material is stressed beyond its yield point, while the sheet metal is stressed below its elastic limit.

Abstract: Disclosed is a piston ring including a spacer-expander spring member. In a preferred embodiment the ring is of cast iron and includes two axially spaced cylinder wall contacting lands. At least one generally rectangular inwardly facing spring receiving recess is formed in the interior wall of the ring to receive the spring member which is formed from a flat strip of metal in a "U" configuration with the legs thereof facing outwardly, preferably aligned with the lands on the ring. A plurality of slots are provided in the spring member dividing the periphery into a plurality of feet. In a preferred embodiment the feet are radiused as seen in plan view to a radius less than the radius of the pocket in which they fit. This has been found to reduce wear in the spring receiving groove and to reduce the tendency of the ring and spring to become united which is detrimental to performance and is a common problem in rings of this general type.
