Abstract: The present invention sets forth an hydraulically operated boat lift for lifting small boats upwardly out of a body of water by simultaneously supplying water pressure to four support posts connected to four corner portions of a lifting frame. Each of the corner posts comprises an hydraulic cylinder with the cylinder body connected to the lifting frame and moveable vertically on its downwardly extending piston rod which forms support legs for the lift.

Abstract: An offset printing process is utilized for printing an acid resist ink onto both sides of a TV aperture mask. Printing is accomplished after the mask has been formed into an approximate spherical or cylindrical shape, and after a peripheral frame has been attached thereto. The resist ink employed is a pressure-sensitive hot-melt composition which forms an acid resistant film when deposited on the mask.

Abstract: A TV bulb and method of manufacture are disclosed. A collector printing process is utilized for applying TV phosphor compounds with associated black background to the inner face of the TV panel. Also, an offset printing process is utilized for printing an acid resist ink on both sides of a TV aperture mask after it has been formed into an approximate spherical or cylindrical shape. Masks and panels produced in accordance with the present invention are interchangeable during bulb manufacture.

Abstract: A collector printing process is utilized for applying thermoplastic pressure-sensitive inks, corresponding to the color TV phosphors and the black matrix, onto the inner face of the TV panel. Separate inks, formed of inorganic pigments and a thermoplastic pressure-sensitive medium, are each separately patterned. The separate inks are then printed in registration onto a collector to form a composite pattern. Upon completion, the composite pattern is completely transferred to the TV panel by contact of the collector against the inner panel face to form the target.

Abstract: A television bulb is set forth which defines various structural relationships within the bulb construction to enable the manufacture of thin, lightweight TV tubes. The bulb is formed from strengthened glass systems such as laminated sheet glass or chemically strengthened glass, and includes a panel and a funnel having mating outwardly-extending peripheral flange portions which are sealed together. In addition to the peripheral flange portion, the panel includes a central viewing section and sloping sidewall portions which are all tangentially connected together.

Abstract: In a flat panel display system including a polyhedral enclosing housing structure having opposed front and back panels, which structure requires a subatmospheric or evacuated environment for the performance of the electronic components contained therein, a plurality of substantially parallel transversely spaced apart and longitudinally extending supporting vanes are fixtured within said housing between said front and back panels for limited movement within said housing prior to evacuating the interior thereof and for engagably supporting said front and back panels against the forces generated by atmospheric pressure when said interior is evacuated.

Abstract: Plastically formable material, which may be formed under pressure into desired shapes, is fed while in a fluid or plastically formable condition to a pair of cooperating surfaces which are relatively movable into compressive relationship with material disposed therebetween. The face of at least one of such surfaces is patterned with a plurality of juxtapositioned geometrical impressions of desired size and shape so as to form a ribbon or sheet of uniformly sized and shaped particles from the plastically formable material supplied to the cooperating surfaces. The uniform particles are initially joined together by thin web or edge portions which maintain the continuity of the newly formed particles within a sheet form.

Abstract: An extrusion die for forming a honeycomb structure having a plurality of interconnected discharge slots provided with a plurality of relatively small sized feed holes directly communicating with intersecting portions of said discharge slots, and a plurality of relatively larger feed passageways each communicating with a plurality of said relatively small sized feed holes, with said feed holes and feed passageways extending longitudinally of said die and the flow through said die such that a portion of such flow may pass directly through such die in a linear path.

Abstract: A television picture tube face plate or viewing panel including a viewing area having a reduced thickness for weight reduction of the face plate or viewing panel and resultant savings in the quantity of glass required in the manufacture of such a face plate. A thickened annular area of the face plate, adjacent and surrounding the outer perimeter thereof, is preferably provided with a selected maximum thickness at or adjacent the ends of the minor axis of the face plate, a selected minimum thickness at or adjacent the diagonal axis of the face plate and an intermediate thickness at or adjacent the ends of the major axis of the face plate, the regions of the face plate at or adjacent such ends of said axes being the regions of the face plate having the greatest, least and intermediate stresses, respectively, when the face plate is part of an exhausted television picture tube.
