Patent CA-1325315-C (CA)
Inventor: BLIXT TONY
IPC: D21H23/04
Filed: 1989-06-21
Granted: 1993-12-21
Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates to a novel sizing composition in the form of an aqueous emulsion comprising a hydrophobic cellulose reactive sizing agent and a cationic polymer comprising a starch, the novel features of said composition being that the starch possesses a combination of (A) a branched, high molecular weight structure as reflected by an amylopectin content of at least 85% and (B) a degree of substitution of about 0.045 to 0.40.     Such sizing compositions can be prepared by dissolving the aforementioned starch in water, adjusting the temperature to above the melting point of the sizing agent and adding the sizing agent to the solution so as to form a coarse emulsion, which is subsequently subjected to shear forces to reduce the particle size of the emulsion.     The invention also relates to a method of preparing sized paper or paperboard by using the above-mentioned sizing composition.  Also, the invention relates to the sized paper for paperboard prepared by said method.  Such paper products show reduction in liquid absorbency as compared to products using conventional sizing agents, reduced consumption of optical highteners, and enhanced development of sizing.

Title: Turbine blade tip clearance control system
Inventor: CANG JOHN N
IPC: F01D5/20
Filed: 1989-07-18
Granted: 1992-02-25
Abstract: Abstract of the Disclosure Turbine Blade Tip Clearance Control System The turbine blade tip clearance control system presently used with existing turbine blade uses an abradable seal material with a conventional squealer tip. Others use a thin, coating added to the tip of the blade.  The present turbine blade tip control system minimizes the problem of controlling the clearance between the blade and the shroud and overcomes the problem of wearing away of the thin coating added to the tip by using a rub tolerant, high-temperature seal material coating on a turbine shroud and a turbine blade made of at least two materials.  The combination of the coating and an outer tip being of a different material than the metallic body also minimizes the problems associated with the burning of dirty fuels.  The blade has a metallic body of high strength and the outer tip has a strength less than the strength of the body and made of a material resistant to oxidation, sulfidation and thermal fatigue at operating temperatures.  The outer tip has a radial length "L" at least lmm in length.     81661130.doc

Title: Ceramic fiber refractory moldable compositions
Inventor: CHI FRANK K
IPC: C04B35/66
Filed: 1989-09-01
Granted: 1997-07-29
Abstract: A moldable refractory composition containing from about 42 to about 83% by weight of a liquid vehicle,  such as water;  from about 13 to 50% by weight of ceramic fiber; from about 0.5 to 7% by weight of an inorganic binder derived  from an inorganic  colloidal  dispersion having active hydroxyl groups capable of reacting with hydroxyl groups of the ceramic fiber; and from about 0.5 to 5% by weight of a high molecular weight organic resin which serves multiple functions including tackifier of the wet composition,  cohesiveness  of  the  wet  composition, appropriate rheology of the wet composition to provide shelf life and a wide range of applications and in dry composition to provide green strength.  Also described is the  method of  manufacture  for the  subject  refractory moldable  composition.    Upon  drying,  the  moldable composition  adheres  well  to  surfaces  such  as  those encountered in furnacing applications  and construction applications to metals and other ceramic materials and dries to give an essentially crack-free refractory shape which exhibits greater resilience than heretofore known moldable  refractory compositions.    The dried moldable composition  is  useful  as  thermal  insulation  at temperatures  up to  1650°C  (3000°F)  dependent upon the type of ceramic fibers and inorganic binders contained as ingredients in the composition.

Abstract: The invention relates to a method for processing the parameters of a speech coder according to the quality of the transmission connection. The quality of the transmission connection is determined in a quality monitoring member (409) on the basis of erroneous/error-free classifications of single received frames so that for determining the quality of the transmission connection the classifications of single frames performed during several subsequent speech frames are scanned. On the basis of the quality of the transmission connection both the replacement procedure of erroneous speech frames carried out in the replacement member (402) and the processing of the frames detected as error-free carried out in the processing member (406) of error-free frames are controlled so that the effect of the transmission errors on the quality of the decoded speech signal remains insignificant. <IMAGE>

Abstract: ABSTRACT            A method and apparatus for synchronizing two inde-pendent rasters, such that a standard TV video and a high resolution computer generated graphics video may each be displayed on a high resolution graphics monitor.  This is accomplished utilizing dual frame buffers. A TV frame buffer, comprises a dual port VRAM, with the serial and random ports operating asynchronously.  The primary port receives incoming TV video synchronously as it comes in, and the secondary port reads the TV video out synchronously with the high resolution graphics monitor.  A high resolution frame buffer in a computer is utilized to store high resolution graphics which is read out synchronously with the high resolution graphics monitor.  A switching mechanism selects which of the TV video and the high resolution graphics video is to be displayed at a given time.  The TV frame buffer includes an on screen and off screen portion.          The computer provides computer data, including high resolution graphics data and audio data to the TV frame buffer, with the graphics data being stored in the on screen portion and the audio data being stored in the off screen portion.  The audio data is read out to an audio circuit for replay.  The graphics data is combined with the TV video for purposes of windowing.
