142 Product method of synthetic silica glass and thermal treatment apparatus US09806236 2001-03-28 US06732546B1 2004-05-11 Shouji Yajima; Hiroyuki Hiraiwa; Yasuji Ishida
A production method of synthetic silica glass according to the present invention comprises a first step of ejecting a silicon compound and a combustion gas containing oxygen and hydrogen from a burner to effect hydrolysis of the silicon compound in oxyhydrogen flame to produce fine particles of silica glass, and thereafter depositing and vitrifying the fine particles of silica glass on a target opposed to the burner to obtain a synthetic silica glass ingot; a second step of heating the synthetic silica glass ingot or the like obtained in the first step up to a first retention temperature of not less than 900° C., retaining the ingot or the like at the first retention temperature, and cooling the ingot or the like at a temperature decrease rate of not more than 10° C./h down to a temperature of not more than 500° C.; and a third step of heating the synthetic silica glass ingot or the like obtained in the second step up to a second retention temperature of not less than 500° C. nor more than 1100° C., retaining the ingot or the like thereat, and thereafter cooling the ingot or the like at a temperature decrease rate of not less than 50° C./h down to a temperature 100° C. lower than the second retention temperature.
143 Device and method for relaxing stress in glass, especially at the base of the neck of a television funnel US10381147 2003-03-20 US20030182965A1 2003-10-02 Ulrich Fotheringham; Hauke Esemann; Bernd Hoppe; Eva Hnullzel; Michael Kluge; Norbert Baumbach
The invention relates to a method for relaxing stress in glass, especially at the base of the neck of a television funnel, comprising at least the following steps: the glass which is to be relaxed is heated from an initial temperature T1 to a holding temperature T2; said glass is maintained at the holding temperature T2 for a period of time t2 until the glass has relaxed; the glass is cooled to a temperature T3 which is always less than T1; the temperature T2 is maintained, and the heating and cooling processes are carried out by means of a regulating circuit comprising at least one temperature sensor for detecting the temperature and one heating unit as a control element. The invention is characterised in that the heating unit comprises infrared beam emitters for heating the glass which is to be relaxed, said beams having a thermal delay time of less than 10 s, especially less than 5 s.
144 Method for fabricating gradient-index rods and rod arrays US09716570 2000-11-17 US06598429B1 2003-07-29 Shibin Jiang; Philip Lam
A method for fabricating gradient-index rods and rod arrays. A central rod of optical glass having predetermined properties and predetermined outside dimensions is placed inside a tube of optical glass having predetermined properties and predetermined outside dimensions, to form an assembly. The inside dimensions of the tube are substantially equal to the outside dimensions of the rod. The tube is formed of a plurality of coaxial sleeves, the outside dimensions of each interior sleeve being substantially equal to the inside dimensions of the next adjacent sleeve, each sleeve having a selected refractive index so that, together with the tube, the refractive indices from the central rod through the outermost sleeve approximate the refractive index profile of the gradient-index rod to be fabricated. The central rod and sleeve material is selected so that their respective thermal indices of expansion are substantially equal. The central rod and tube assembly is placed in a mold having inside dimensions substantially equal to the outside dimensions of the tube. The mold is oriented vertically so as to ensure that there is no net lateral gravitational force on the assembly. The mold is then heated with the central rod and the tube therein at a predetermined temperature for a predetermined time so as to cause a selected amount of diffusion of material between the central rod and the sleeves and thereby produce a radial refractive index gradient. The temperature is then gradually reduced to anneal the glass. The cooled glass comprises a preform which is then drawn into a gradient-index rod. Gradient-index elements fabricated in accordance with the invention may be placed into a substrate and drawn into elements that have a desired external shape while retaining the optical properties of a radially symmetric, cylindrical gradient-index rod. Arrays of gradient-index rods fabricated using the invention may also be bonded together or imbedded in a substrate.
145 Kiln formed glass headed golf club putter US09955213 2001-09-17 US20030054899A1 2003-03-20 Michael Dupille
A strengthened triangular shaped glass putter head made by a specific shape dependent fusing and annealing process using 90 COE or 96 COE soda lime glass. The putter head has smooth surfaces or is patterned with individually colored bas-relief design decorations. The putter head may be colorless, single colored, multi-colored, or semitransparent to opaque in appearance. The putter head is sufficiently strong to play a more rigorous putting-based golf game.

147 Method for fabricating a glass CRT panel US657085 1984-10-03 US4566893A 1986-01-28 Maxwell M. Hopkins; Arthur Miller
A method for fabricating a glass CRT panel that exhibits high compressive surface stress and low compaction comprising thermally processing the panel during the initial annealing stage for a prescribed period of time at about those temperatures that produce minimum compaction, which processing temperatures are substantially lower than the processing temperatures that produce minimum surface stresses in the panel, and then cooling the panel to room temperature.
148 Method of heat treating glass in a fluidized bed and apparatus therefore US805568 1977-06-10 US4120680A 1978-10-17 Raymond Peter Cross
A fluidized bed for the thermal treatment of glass articles is maintained in a quiescent uniformly expanded state of particulate fluidization by establishing a high pressure drop across a porous membrane through which fluidizing gas is supplied to the bed, of at least 60% of the pressure at which the fluidizing gas is supplied to a plenum chamber beneath the membrane.
149 Perforate glass structures and method of making the same US128598 1970-12-21 US4101303A 1978-07-18 John Treagus Balkwill
A channel-type electron multiplier made in the shape of a glass wafer having holes through a central portion thereof, and an imperforate glass border fused to the periphery of the wafer, the wafer glass having a thermal coefficient of expansion less than that of the border glass. In manufacture, a brief fast cooling step aids in the production of a strong, permanent bond between wafer and border.
150 Method for reducing thermally induced fracture of cathode ray tube bulbs during salvage US568954 1975-04-17 US3988136A 1976-10-26 Melvin F. Rogers
Method for reducing the likelihood of cathode ray tube glass bulb and bulb component fracture caused by temperature cycling during tube salvage. The depicted salvage method includes heating and then cooling the exterior surfaces of a glass front panel and glass funnel to be separated, thus producing a temperature gradient between the front panel extreme border and more remote inner portions of the front panel extreme border. This temperature gradient causes circumferential tension at the front panel extreme border. The circumferential tension is reduced to thus lessen, the likelihood of front panel fracture by applying, prior to or during, said cooling, a thermal insulator over the front panel extreme border and vicinity so as to locally reduce the rate of glass surface cooling.
