Abstract: The swimming pool cover system is used for removably covering any type of swimming pool and for preventing objects or persons from falling into the pool. It comprises a flexible cover sheet having an outer edge removably connectable to locations along the swimming pool periphery. For covering the pool, the outer edge of the sheet is connected to the pool periphery and a central portion of the sheet is connected to a tautening cable mounted on a boom member extending over the pool. The sheet is then suspended and tautened above the water surface. The cover system comprises a sheet bundle cable mounted on the boom member for bundling up the sheet above the water surface when the cover system is in an uncovering position. The swimming pool cover system is very advantageous over other swimming pool covers because it is very simple and rapidly installed or removed. It may be very easily bundled up and stored away when not in use.

Filed: 1995-10-12
Abstract: A parallel shear apparatus (10) for sequentially shearing each of a plurality of streams of molten glass (A,B,C,D) from a glass feeder into gobs for processing into glass containers by a glass forming machine. The apparatus (10) has first and second opposed carriages (12, 14) which are reciprocable along parallel slides (16, 18, 20) toward and away from one another, each of the carriages carrying one or more opposed knife elements (32a, etc., 34a, etc.), corresponding to the number of streams of molten glass, and the opposed knife elements (32a, 34a, etc.) overlap at the innermost limits of their travel to perform the shearing action.

Abstract: A novel packaging of semiconductor elements, such as MCM tiles, with a variety of printed circuit or wired boards (PWB), the packages occupying a small size, at least in the vertical direction, relative to prior art OMPAC devices. The MCM tile includes an interconnection substrate with peripheral metallizations and at least one chip or integrated circuit (IC) mounted on the substrate by solder reflow or conductive adhesive technology. The PWB which may be a single level or a multilevel, is provided with an aperture for accommodation of at least one chip therein. Depending on the type of interconnection between the substrate and the PWB, the aperture may be larger than the substrate of the MCM tile for wire bonding interconnection or smaller than the substrate for solder reflow or conductive adhesive interconnection. In the wire bonding case, the MCM tile is positioned within the aperture resting on the surface of the PWB or of a structural member or of a heat sink which encloses one end of the aperture. The other end of the aperture may be open or enclosed by a structural member, a heat sink, another PWB or a mother board. For solder reflow or conductive adhesive interconnection, the substrate which is larger than the aperture is positioned so that its ends overlap areas of the PWB adjacent the aperture and the chips and/or substrate are positioned within the aperture. The interconnections are enclosed in a compliable encapsulating material, such as silica gel.
