Title: Method of providing a clamping band around the bulb of a television picture tube and implosion-free tube manufactured by means of this method
IPC: H01J29/87
Filed: 1967-09-12
Abstract: A method of assembling an implosion inhibiting clamping band 7 around the glass bulb of a TV display tube so that the faceplate of the bulb between the front surface and the mould-match line 4 remains uncovered comprises arranging the clamping band over an intermediate band 6 around the bulb adjacent the mould match line and securing the intermediate band to the bulb and to the clamping band. A steel strip 6 is wrapped around a substantially rectangular face-plate 1 and secured by polyvinyl acetate with polyester, polyurethane or epoxy resin adhesive which may extend to the mould match line. The strip 6 extends over the seal 3 between the faceplate and the cone 2 and carries fastening lugs 11. The space between the band and cone is filled with synthetic resin 12. Two Cr-Ni steel bands 7, 71 are tensioned around band 6 and a lubricant is provided to reduce friction, thereby achieving uniform tension. Alternatively a clamping band with several joints may be used or a steel strip, welded at one end to band 6, is wound round under tension and its other end welded to the first end. Preferably, band 6 is uninterrupted and positioned on the tube when hot. Spacing blocks may be inserted between bands 6 and 7 or between band 6 and the face-plate to increase pressure on the straight faces of the face-plate.

Title: Method of retreading tires
IPC: B29D30/56
Filed: 1972-08-31
Abstract: A tread strip is positioned in proximity to the outer periphery of a tire carcass. A bonding substance is provided intermediate the carcass and the strip and has adhesive characteristics sufficient to temporarily bond the strip to the carcass when the strip and carcass are pressed together. The bonding substance is also sufficiently plastic to result in intimate contact by the substance of the facing surfaces of the strip and the carcass when the strip and carcass are pressed together. The bonding substance, for example unvulcanized rubber, is capable of permanently bonding the strip to the carcass when the bonding substance is sufficiently heated. Initially, the strip and carcass are pressed together in such a manner as to expel gases from between the strip and carcass and in such a manner as to cause the bonding substance to temporarily bond the strip to the carcass. The bonding substance is heated to a temperature resulting in permanent bonding of the strip to the carcass, and during the heating step, escape of the bonding substance from between the strip and the carcass is prevented.

Title: Annealing of NiTi martensitic memory alloys and product produced thereby
IPC: C22F1/10
Filed: 1974-12-04
Abstract: A process for increasing the tensile strength of a martensitic alloy of titanium and nickel and for improving the alloy's ability to retain its original properties during use by stabilizing it against progressive elongation when cycled through successive martensitic transformations. The process comprises maintaining the alloy under a tensile stress of between about 30,000 and 100,000 psi while annealing the alloy at a temperature above a first diffusional phase transformation temperature. The first diffusional phase temperature is the first temperature above the martensitic transformation range at which there is a negative slope in the electrical resistivity versus temperature curve for the alloy. The product of this process has a tensile strength of at least about 175,000 psi and a martensitic elongation activity under stress of at least about 2% and will survive over one million martensitic transformation cycles when placed under sufficient stress that the elongation activity is about 2%.
