Abstract: Abstract of the Disclosure A continuous process for the production of alcohol, preferably  ethanol,  from cellulosic materials.  The cellulosic materials are delignified such that the hemi-cellulose and the cellulose can be subsequently acid hydrolyzed  into  simple  sugars.   These  sugars  are fermented in the presence of yeast to yield ethanol and carbon dioxide.  The alcohol vapor is removed from the fermentation solution under a  reduced pressure and subsequently distilled.  Carbon dioxide gas may be sparged throughout the fermenting solution in order to aid in the removal of the alcohol from the fermenting solution.  The gaseous carbon dioxide is captured and utilized in the manufacture of additional quantities of ethanol or other basic chemicals.

Abstract: Abstract of the Disclosure A method for the heat treatment of metal strips which comprises heating and cooling a metal strip while allowing the strip to pass through a heat treatment apparatus in a floating manner.  When passing through the apparatus in such a manner, the strip is curved in the wave forms in the direction of feed thereof.  Such curvatures given to the strip increase the resistance of the strip against buckling stress.  The increased resistance of the strip against buckling stress is stronger than the thermal stress produced therein during the heating and cooling treatment so that the strip can be heated and cooled without any wrinkles produced therein.

Abstract: ABSTRACT OF THE DISCLOSURE             A feed of lipid and solvent is concentrated in a chamber by establishing and maintaining within a chamber a net major flow and a separate and distinct net minor flow.  A net transfer of solid phase lipid is effected from the major internal flow to the minor internal flow thereby concentrating the minor flow.  However, the minor flow is preferably essen-tially all in liquid phase when it is withdrawn from the chamber.  The mixture flow process is of the fractional crystallization separation type but involves less expensive equipment and energy requirements.

Abstract: ABSTRACT OF THE DISCLOSURE:           For a production of hot gases, solid carbonaceous fuel is fed into the charging end of the rotary kiln.  Oxygen-containing gases are blown through nozzle blocks into the charge disposed over nozzle blocks in the heating-up zone at and behind the point where ignitable particles of the solid fuel first appear.  To decrease the heat requirement for the production of a highly reactive quicklime, oxygen-containing gases are blown through nozzle blocks into the charge disposed over nozzle blocks in that region of the heating-up zone which begins with the appearance of ignitable particles of the solid fuel and which ends where the tempera-ture in the charge does not rise further.  In the succeeding calcining zone, oxygen-containing gases are blown through nozzle blocks into the charge disposed over nozzle blocks and at such rates that the temperature in the charge remains constant.  Oxygen-containing gases are blown into the free kiln space where the kiln atmosphere contains combustible gaseous constituents.  The rates of oxygen-containing gases blown into the free kiln space are so controlled that the exhaust gas is virtually free from combustible gaseous constituents.

The blade has a main convex edge which is doubly beveled.  Spaced along the edge are two pair of transverse projections.  The transverse projections each have a tapered leading edge and a tapered trailing edge on either side of a peak.  The peal< extends from the edge of the blade inwardly to at least the depth of the channel of the came used in stained glass panel construction.  The blade has a trailing edge which is also doubly beveled and which extends from a substan-tially normal intersection with the main blade edge to form a con-cave curve with the handle.  On the opposite side of the handle is a concave upper edge which intersects with the main blade edge to form a point.  A second blade is transversely mounted on the oppo-site end of the handle.  It has a thin edge which extends trans-versely to the handle terminating in a substantially rectangular corner at one side and a smoothly radius corner at the opposite side.  The handle and the blade are concavely curved along the edge joining the trailing edge of the first blade and of a length such that a portion of the handle and the second blade rests in the palm of the user's hand and the user's index finger tip rests on the upper edge of the blade when the hand is placed along the handle.

Abstract: ABSTRACT      A scanning beam display system is used as a projection display and as a reflective flying-spot scanner using a plurality of photoreceptors to sense depth.  Used as a display, the projection of a document-size image from overhead onto a work surface such as a printed form provides a naturally oriented, non-invasive display.  Beam modulation and contextual subtraction permit the flying-spot function in ambient light.  Used as a combination display and scanner, inherent registration of the display and data input functions permit interaction with an operator by displaying on and sensing from any document or work object.  A plurality of non-overlapping sensors operate with the flying-spot function to receive images alike in perspective but differing in shadow placement, from which relative distances and object boundaries are easily derived.  Used without the display function, a visualization of a work area is obtained that is much more interpretable by a computer than with standard visual parallax for improved robotic visual perception. Acting in concert, the methods of this invention form a touch sensitive image on a work surface devoid of display or sensing hardware.

Abstract: ABSTRACT OF THE DISCLOSURE         The turbine blades of a high pressure turbine in a gas turbine jet engine are cooled by cooling air injected into cooling channels in the blade using angled nozzles supplied with high pressure air from the engine compressor.  The nozzles project the high pressure air across a lower-pressure gap into slots which lead to internal channels in the turbine disk without requiring the use of seals to produce a pressure differential to encourage the flow of cooling air.  Maximum air transfer into the internal channels in the turbine blades occurs when the air impacting slots in the turbine wheel is travelling at an angle with respect to the slots which is approximately parallel to the axes of the internal channels.          A relatively narrow range of angular misalignment for aiming the nozzles is permitted.  The pressure of the air from the plenum may be reduced by employing two or more flow channels in series before projecting the air across the gap to the turbine wheel.

Granted: 1986-02-25
Abstract: ABSTRACT         This invention relates to a system for attaching a plastic liner to a substrate such as a hopper, railway car or truck body.  A plastic liner is attached to a substrate using a bolt with a plastic capped head that is received in an enlarged recess at the exposed liner surface to be flush with said sur-face and that has an attachment shank that extends through a shank opening in the liner at the bottom of the recess and into the substrate.  Means are pro-vided for engaging the shank and securing the shank to the substrate.  The recess is straight sided.  The cap is straight-sided and includes a peripheral portion that extends around the periphery of the bolt head and is peripherally smaller than the recess.  The peripheral portion includes a radially outwardly ex-tending flexible sealing skirt that is peripherally larger than the recess in an unconfined state and in its confined state is rolled upwardly into sealing engagement with the sides of the recess.  In a pre-ferred embodiment, a squared portion on the bolt shank deforms a liner opening to provide a nonrotatable engagement, and there is a plastic wear washer to accommodate lateral movement allowed by an oversized substrate opening.  The system is readily adapted for field installation using conventional tools.
