Abstract: METHOD AND APPARATUS FOR GENERATING HIGHLY LUMINOUS FLAME                     ABSTRACT         Disclosed is a method of combusting combustible material and a burner therefore to generate a high temperature, high luminosity flame with low NOx emission.  There is a combustion tunnel having an outlet opening and combustible material and two different oxygen-based oxidizing gases are separately supplied to a combustion tunnel.  The first oxidi-zing gas having a given oxygen concentration and a first portion of the combustible material is separately directed into a combustion tunnel  toward the outlet opening such that the portion of combustible material and the first oxidi-zing gas mix within the combustion tunnel to create a flame core.  The remainder of the combustible material and the second oxidizing gas  is separately directed into the combustion tunnel toward the outlet opening such that the remainder of combustible material and the second oxidizing gas mix together prior to mixing with the flame core.  The mixture of combustible material and the second oxidizing gas is caused to subsequently mix with the flame core to create the final flame pattern.

Title: Use of seawater in flue gas desulfurization
Inventor: ABRAMS JACK Z
IPC: B01D53/50
Filed: 1988-06-16
Granted: 1992-06-23
Abstract: USE OF SEA WATER IN FLUE GAS DESULFURIZATION            ABSTRACT OF THE INVENTION Efficient removal of sulfur dioxide from a flue gas stream is achieved in a scrubber using a recirculating aqueous stream containing magnesium hydroxide and magnesium sulfite which together act as a SO2 absorbent.  Magnesium sulfite is derived from magnesium hydroxide, which is the product of a reaction between soluble magnesium from the seawater and calcium hydroxide added to the scrubbing system.  Magnesium sulfite and bisulfite are oxidized to magnesium sulfate by the introduction of air.  Magnesium sulfate is converted back to magnesium hydroxide by reaction with additional calcium hydroxide, with gypsum as a by-product.  Gypsum is soluble in large amounts of seawater and may be returned to the ocean without adverse environmental impact.

Title: Shaped articles made from pre-processed starch
Inventor: STEPTO ROBERT F T
IPC: C08J5/00
Filed: 1988-08-10
Granted: 1994-04-26
Abstract: ABSTRACT       The invention refers to a process of forming shaped articles from starch and to such articles.  The process comprises: (a) heating a composition comprising a pre-processed and essentially destructurised starch/water material, at a water content in the range of from 10 to 20% by weight based on the weight of the composition to a temperature sufficient to essentially destructure the starch;          (b) transferring the melt to a mold while maintaining said water content; and (c) cooling the melt in the mold to a temperature below its glass transition temperature to form a solid shaped article.  Thus according to the present disclosure, the starch is destructurised initially and then solidified before being re-melted prior to its shaping into articles.  This separation of the shaping step from the initial destructurising step yields articles having improved physical properties.

Abstract: Methods of and Apparatus For Coating Optical Fiber and Products Produced Thereby Abstract An optical fiber (21) which has been drawn from a preform (22) is moved into and through a chamber (38) of a housing. A source of vacuum is connected to the chamber to prevent the attachment of air pockets to the optical fiber as it is being moved through the chamber and through an opening of a die. The die includes a flow path (55) which is substantially normal to the path of travel of the optical fiber and the die opening is substantially larger than the diameter of the optical fiber. The thickness of the flow path in a direction along the path of travel is sufficiently small so as to prevent the recirculation of the coating material inthe vicinity of the point of application to the optical fiber. Also, the fiber draw rate, the pressure of the coating material the direction of the flow path relative to the longitudinal axis of the optical fiber and the diameter of the die opening are such that a gap forms between the coating material and the die. That gap is allowed to be maintained because of the pressure differential between ambient atmosphere and the chamber. As a result, the coating material as it leaves the disc-like flow path and is directed toward the optical fiber is bounded by free surfaces instead of by solid surfaces in the immediate vicinity of where it is applied to the optical fiber. This prevents the development of shear fields and allows the diameter of the coated optical fiber to be varied.
