Abstract: ABSTRACT OF THE DISCLOSURE     Two-way advantages are obtained by the invention in which valuable lightweight building materials with high mechanical strengths are obtained by the utilization of otherwise noxious and hardly-disposable sludge of gel-like aluminum hydroxide produced in large quantities in the process of the anodization treatment of aluminum shaped articles to cause a problem of environmental pollution.  According to the inventive method, the aluminum hydroxide sludge is first admixed with a calciferous material which is preferably a combination of calcium oxide and a gypsum so that a reaction takes place between them to form ettringite and the thus obtained ettringite-containing mixture is blended with a fibrous reinforcing material such as a cellu-losic pulp or asbestos and, optionally, a Portland cement to form a blend which is shaped into a desired form of, for example, wall or ceiling board followed by curing and drying.

Abstract: Abstract A process for modifying the surface characteristics of a pre-formed polymeric substrate to impart hydrophilicity, hydrophobicity, or other desired properties thereto, by peroxidizing the surface of the substrate and then allowing the active sites along the polymer chains to generate free radicals which induce graft polymerization of a suitable ethylenic monomer (or other ethylenically-unsaturated compound) onto the surface of the substrate is described.  Such graft copolymerization is undertaken in the presence of variable valence metal ions in a reduced state under acidic conditions and at selected reaction times and relatively low temperatures, and in the presence of squarate ions (diketocyclobutenediol) to control tbe physical characteristics of the surface graft and to restore the metal ions to their lower valence state without at the same time producing deleterious by-products.

Abstract: ABSTRACT OF THE INVENTION      The invention lies in the field of fluid valves and discharge nozzles and more particularly pertains to fluid discharge nozzles wherein a particular discharge pattern, having an automatic continuously changing direction, is desired.  The fluid discharge nozzles have particular application in hydrotherapy and are adapted to discharge a turbulent air-water admixture for this purpose.  The valves disclosed herein are constructed so as to produce a discharge jet of an intimate water-air admixture, the discharge pattern being generated covering a conical or annular surface of revolution or variations thereof.  The valves disclosed herein also produce a discharge jet which is readily variable in its rate of discharge of the inti-mate admixture of air and water.  The fluid valve of this invention is therefore capable of therapeutic massaging action over a continuously changing surface area.

Abstract: ABSTRACT OF THE DISCLOSURE          The present invention relates to a method for checking flat transparent surfaces permitting the discrimination between the flaw in the matter and dirt which has been deposited on the surface but does not affect the flatness or the transparency of the sheet. The apparatus includes a photosensitive captor located above the sheet to be checked. The captor is arranged at the limits of a fuzzy real image which an optical system gives in the plane of this captor of a light source located below the sheet. In this way, a flaw causes the excitation of the captor at a level higher than the normal light threshold of the fuzzy image because of refraction caused by the flaw in the matter. In contrast, the presence of dirt will cause, through occultation, an excitation lower than the normal light threshold thereby enabling differentiation between the flaw and the dirt. The apparatus further includes an electronic assembly for analyzing the signals provided by the captor for driving a device for marking the surface bearing a flaw at the exact spot where the flaw is located. The present invention may be used for checking glass sheets during their manufacturing in continuous or cut out glass sheets for example.

Abstract: ABSTRACT OF THE DISCLOSURE     An   improved   method   for   recovery   of   metal, particularly  aluminum,  from  metal  bearing  dross  (14) utilizes  a  trough  (13)  for  collection  of  the  dross (14).  A wedge member  (28) compresses the dross (14)  in the trough (43).  In this manner, metal is decanted from the  compressed  dross  and  flows  through  slots  in  the bottom or passages  (25)  in the walls of the trough (43) for collection in a pan (26), or becomes concentrated at the edges or walls of the volume of dross. The trough (43) and wedge members (28) also serve to cool the dross material thereby diminishing metal loss due to thermite reaction.    The   compressed   dross   coalesces   and solidifies,  is  broken  and  is  mechanically  separated. The larger dross components from the separation process are substantially metallic and may be recycled through the furnace (10).  The remaining components are charged in a vortex melting furnace (36) for the lowest possible melt  loss.   This  also  effects  segregation  of  the remaining metal from the dross by melting the metal and allowing the dross to rise to the top of the bath.  The improved method  of  the  present  invention  provides  for recovery of  about  95%  of aluminum metal  from a dross which  contains  about  70%  aluminum as  compared with  a recovery rate of  about  50%  aluminum metal utilizing  a generally known prior art technique.

Abstract: Abstract of the Disclosure In order to keep the opening for inserting a catheter into a blood vessel as small as possible, a catheter insertion tube is used which coaxially surrounds the puncturing canula and consists, at least in a circumferential area and/or at least along a portion of its length, of one or several dilatable or expandable areas permitting enlargement of its internal diameter.  The diameter of the catheter insertion tube, at the front end where it is inserted into the blood vessel, is approximately equal or smaller than the outer diameter of the catheter.  The catheter insertion tube is expandable at least over the front or forward portion of its length by the catheter.  The catheter insertion tube is removable from the puncture over the catheter while the catheter is advanced into the puncture and is tightly sealed by the catheter because the catheter has an external diameter equal to or larger than the puncture previously occupied by the insertion tube.

Abstract: ABSTRACT OF THE DISCLOSURE           A method of stitching a pattern on fabric employs a piece of interwoven netting having rows of square holes and the desired pattern printed thereon.  The netting is attached to the fabric so that the pattern on the netting directly overlies the area on the fabric where the pattern is to be reproduced.  The pattern is then stitched onto the fabric using a needle and embroidery threads.  The stitch that is used is a cross-stitch wherein the thread is pushed up from the inside surface of the fabric and through the center of a hole in one row of the netting and then crossed over an intersection of the netting on a 45° angle to the threads forming the netting.  The thread is then pulled down through a hole in an adjacent row and through the fabric.  Upon completion of the stitched pattern, the netting is removed by drawing out the threads thereof one strand at a time.  A kit is also provided to enable one to carry out this method.
