Title: Thermally stable positive resist
Inventor: TOUKHY MEDHAT A
IPC: C08L61/06
Filed: 1984-10-18
Granted: 1990-02-20
Abstract: ABSTRACT           A thermally stable, positive resist is provided which is useful in ultra violet lithography.          The positive resist composition contains a polymer system, a sensitizer system, and a solvent for the polymer system and the sensitizer system.  The polymer system contains a phenolic resin, and pref-erably a novolak-type resin compatible with the phenolic resin.  The sensitizer system contains a photosensitive agent and a thermosensitive cross-linking agent for the phenolic resin.  The photosen-sitive agent is a diazoketone compound insoluble in aqueous alkaline solution that absorbs radiation in the near ultra violet region of the spectrum pro-viding decomposition products soluble in aqueous alkaline solution.  The thermosensitive cross-linking agent is a bisarylazide compound that absorbs radiation in the deep ultra violet region of the spectrum and that cross-links the phenolic compound when exposed to elevated temperatures.

Abstract: PROCESS AND INSTALLATION FOR THE BIOLOGICAL TREATMENT OF SEWAGE                  ABSTRACT OF THE DISCLOSURE          The present invention relates to a compact sewage treatment method and apparatus, especially for sewage that is highly biologically charged, in which a secondary settling basin is disposed within an activator basin.  A portion of the sludge separated within the settling basin is aerated, mixed with liquid separated within the activator basin, and also aerated and recycled to the activator basin.  This mixed flow is at least partially degasified before recycling into the activator basin, and again aerated, if required. Uniform loading and reaction is achieved with the present invention since volumes can be reduced while maintaining the same flow rates as compared with previous installations, due to the specific design and operation of the apparatus and process of the present invention.  A star-shaped arrangement of the respective aeration components, suction components, and mixing components about the activator basin is one embodiment of such a design and operation thereof.

Abstract: ABSTRACT          Potassium chloride and sulfuric acid are reacted in a recycled aqueous solution in the stoichiometric ratio required for potassium sulfate production.  Hydrogen chloride produced by the reaction of the potassium chloride and sulfuric acid is evaporated in admixture with water or in anhdrous form.  The resulting solution is cooled to crystallize a potassium sulfate salt, preferably potassium bisulfate. The potassium sulfate salt is separated from the mother liquor and the mother liquor is recycled to the reaction step.  The potassium sulfate salt is dissolved in an aqueous solution and sequentially decomposed to produce potassium sulfate and a mother liquor rich in sulfuric acid.  The mother liquor rich in sulfuric acid is concentrated and recycled to the reaction step.

Abstract: ABSTRACT OF THE DISCLOSURE            A  camshaft is prepared from separately formed cams and  a shaft.   The cams may for example be formed by  sintering.          The cams are provided with holes which are under-sized and are  provided  with  serrations.   They are located  on  a correspondingly    shaped  dummy shaft in  their  required relative orientations and angular  positions.   Next,  the cams  are  clamped in these positions and the dummy  shaft removed.   The  cams are then heated to red heat  and  the serrated holes in them   broached to bring them to   their final size and to concentricity.   Finally, a shaft having an exterior profile corresponding to the shape and size of the broached profile of the holes, at ambient temperature, is  introduced  into  the holes and the  cams    are  then cooled  so  that  they    shrink fit on to  the  shaft  so ensuring that they are accurately positioned on the shaft.   The cams are then released from the jig to give a finished camshaft.

Abstract: CONTROL OF BROWNING REACTIONS          IN BAKED GOODS BY ADDITION OF               SODA AND AN EMULSIFIER     Abstract A method for reducing excessive browning in a baked good containing reducing sugars is described. The method comprises adding to the dough of the baked good about 0.1596 to about 0.65% baking soda and about 0.10% to about 0.65% fatty acid monoglyceride esters of polycarboxylic acids and their derivatives. This combination of ingredients minimizes browning while avoiding off-flavor often associated with the addition of leavening agents to control browning. The invention is particularly useful with dual-textured cookies wherein a chewy region is made from a dough containing reducing sugars or crystallization-resistant sugars, and wherein a crisp region is made from a dough containing sucrose or readily crystallizable sugars. Browning is minimized in the reducing sugar-containing inner dough so that if the inner dough shows on the cookie surface it does not create an unattractive appearance.
