Abstract: 48,003 ABSTRACT OF THE DISCLOSURE         The  turbine  section of  a  gas  turbine  engine includes structure in the disc cavity for separating high pressure  air  into  cooling  air  for delivery  to  cooled blades and sealing air for preventing hot motive  fluid from entering the cavity.  A disc cavity seal is provided to minimize leakage of the sealing air into the motive gas path resulting in increased air pressure on the air separ-ator structure (which is integrally attached to the rotor) and  providing  a  balance  piston  for  counteracting  the normal thrust on the rotor and reducing the thrust bearing load.  The resultant decrease in leakage of high pressure air also improves the engine performance efficiency.

Abstract: Abstract of the Disclosure:         An apparatus for continuously producing a high strength dual-phase steel strip or sheet having a chemical composition which produces a dual-phase structure composed of ferrite grains and a low temperature transformed phase when rapidly cooled from the (.alpha. +.gamma.) temperature range or from the y temperature range.  The apparatus has a continuous heat treatment furnace in which the strip moves vertically and which is composed of a heating zone, a soaking zone and a cooling zone, and conventional equipment associated therewith.  The cooling zone has an upper hearth roll group, a lower hearth roll group and cooling equipment for cooling the strip at a rate in the range between 1 and 300°C/sec. for retaining the austenite in the steel of the strip.  The hearth rolls of each hearth roll group are arranged to guide the strip coming from the soaking zone up and down through the cooling zone from the inlet end to the outlet end, alternately passing around the upper hearth rolls and the lower hearth rolls.  The hearth roll at the position where the strip is subjected to straining and begins to work harden as a result of the bending, and the hearth rolls subsequent to such position, have diameters such that the strain induced phase transformation of the retained austenite and consequently the work hardening of the strip when it is turned around the hearth rolls is avoided.

Each strip connects upper and lower corner shielding plates on one side of the picture tube.  The shielding plates guide stray magnetic flux into the strips and away from the picture tube interior in order to provide magnetic shielding.  A degaussing winding is wound around the vertical axis of each strip and generates a degaussing flux which flows through the shielding plates and into the color picture tube shadow mask.

The valve member serves not merely to prevent leakage but to control the inflow and outflow of liquid from the measuring chamber.  Thus ports are not necessary and the disadvantages associated with ports are eliminated.

Abstract: ABSTRACT:-A process for washing fabrics includes the steps of contacting the fabrics with a liquor containing a detergent active compound and an orthophosphate and subsequently contacting the fabrics with a liquor containing a tripolyphosphate.   The tripolyphosphate may be added to the orthophosphate-containing liquor or may be present in a separate liquor.   In the former case the tripolyphosphate may be present from the start of the wash but in a form to delay its dissolution in the liquor, such as by being encapsulated, cogranulated or contained in a sachet.   Delay times of about 5 minutes are disclosed.   The method leads to reduced incrustation on fabrics.

Abstract: Abstract of the Disclosure Sulfur dioxide in the stack gas from an industrial process is converted to elemental sulfur in a Claus reactor at low temperature to produce sulfur fume.  The sulfur is condensed by direct heat transfer with a continuously flowing countercurrent recirculating catalyst and a substantially sulfur dioxide-free gas is discharged.  Catalyst and condensed sulfur are fed into the top of a sulfur recovery column and heated in the top of the column by direct heat transfer with a countercurrent stream of recycle gas.  The sulfur and catalyst descend into a vaporization zone of the column where sulfur is vaporized.   The vaporized sulfur is carried by the recycle gas back towards the top of the column and condensed to a fume by incoming sulfur bearing catalyst.  The sulfur fume is carried from the top of the column in cold recycle gas. Hot catalyst from the vaporization section of the column is cooled by recycle gas entering the bottome of the column. Sulfur fume is recovered conventionally.  Regenerated catalyst from the column is returned to the sulfur dioxide reactor.     Claus plant tail gas with air passes into the base of an incinerator and passes countercurrent to recycled heat transfer solids and is oxidized to convert sulfur and sulfur bearing compounds to sulfur dioxide.  The sulfur dioxide is then converted to sulfur in the process just described.

Abstract: ABSTRACT Method and apparatus are disclosed for making 35 mm color slides from a color image created on a color cathode ray tube (CRT) terminal. The color terminal transmits commands to a remote central processing unit (CPU) that in turn operates a 35 mm camera device to expose 35 mm color slide film. Prior to transmitting the commands, a black on white facsimile of the color image is created by a graphic printer located at the color terminal. The black and white facsimile uses different halftone dot patterns in a monochrome graphic image to simulate the different colors created at the color terminal. The halftone dot pattern density is related to the luminance of the color it represents and the scale of the dot pattern is large to enable ready detection by the human eye. Also, different dot patterns are used for different colors and on edge enhancement technique is used to distinguish one simulated color region from another in the monochrome image.

One or prefer-ably both pintle supports in each pair of bearing devices are formed with means permitting them to be secured to the respective beam in a finite number of different axial positions, whereby the rotor can readily be adjusted to receive bobbins of correspondingly dif-ferent nominal width. Additionally, at least one pintle in each pair of opposed bobbin bearing devices is axially displaceable relative to  its pintle support between an advanced position in which a bobbin is held securely between the opposed pintles for rotation therewith, and a retracted position utilized for load-ing and unloading the rotor.

Abstract: Method of forming a color image of a graphic object pattern directly on a support medium. A water-soluble photosensitive stencil material is coated on the support and exposed imagewise to actinic radiation. The exposed photosensitive stencil material is developed to remove the water-soluble, unexposed stencil material. A layer of water-permeable, water-insoluble color medium is applied. The color medium is treated with water or an aqueous solution to permeate the color medium and soften the stencil material which is removed by mechanical action. Alternatively, a water-insoluble photosensitive stencil material, which becomes water-soluble on exposure to actinic radiation, may be coated on the support.
