Title: Composite photocatalyst for refractory waste degradation
Inventor: LANGFORD COOPER H
IPC: B01J31/06
Filed: 1986-10-02
Granted: 1991-08-20
Abstract: Abstract of the Disclosure The  invention  is  concerned with  a  composite photocatalyst for refractory waste treatment,  comprising particles  of  a  wide  band  gap  semiconductor  material selected  from  the  group  consisting  of  titanium  oxide, cadmium sulfide and cadmium selenide,  the particles being coated with a polymer film capable of absorbing a refrac-tory  waste  substrate  to  be  treated  and  comprising  a pyridine-containing polymer and a divalent metal porphyrin or metal phthalocyanine-based dye.  The dye is molecularly dispersed throughout the film and chemically bonded to the pyridine-containing polymer.    Upon mixing of the photo-catalyst with the refractory waste substrate and irradi-ation with light having a wavelength of about 300 to about 400 nm,  the photocalyst of the invention generates in the polymer film thereof reactive species which are sufficient-ly oxidizing  to  degrade  the  refractory  waste  substrate absorbed in the polymer film.

Abstract: Abstract of the Disclosure Disclosed is a screening paste  for covering a selected  portion  of  a  metallurgical  pattern  on  a substrate while  leaving other metallurgy uncovered. The paste is free of polymers and consists,  in one example, of 75-80% of a ceramic particulate (such as alumina),  2-8% amorphous fumed silica and 15-20% of linear  alcohol.   The  linear  alcohol  serves  as  a vehicle to deliver the solid particles in the paste. In use,  after covering the selected portion of the metallurgical  pattern  with  the paste,  the  alcohol content therein is expelled by subjecting to vacuum treatment at room temperature or  heating to a  low temperature below about  275°C  thereby obtaining an inert,  dry and crack-free protective coating.   Upon evaporation of a new metal layer onto the substrate and removal of the protective coating and new metal layer from everywhere except the uncovered metallurgy, the metallurgical pattern is selectively coated with the new metal.

Abstract: ABSTRACT OF THE DISCLOSURE     A split ring spring for snap fasteners has a burr extending from each end of the ring spring in a direction parallel to the imaginary central axis of the ring spring.          When a stud member is snapped with a socket member in which the split ring spring is incorporated, the burrs do not damage or scar a body of the stud member.  The ring spring having such unobjectionable burrs is produced by feeding a length of a strip of resilient material transversely across a mandrel, then severing the length off the strip in a direction parallel to the longitudinal axis of the mandrel while holding the length on the mandrel, and thereafter bending the severed length of strip around the mandrel.

These parts are connected with one another on one side by means of a hinge, and on the opposite side by means of a snap clasp.   It can thus be opened and closed easily.  In order to ensure that the jewelry clasp is not lost, two cams directed inwardly toward the central opening are attached to the upper part.          Eyelets  are attached to the ends of the chain, which  are  50 dimensioned  that  their  internal diameters  are  larger than  the thickness  of the jewelry clasp ring and smaller than the thickness of the ring plus the height of the cam.  With such dimensioning,  the chain and eyelets can only be attached  to  a  position  differing  from  the supporting direction on the upper clasp part, and the danger of loss is avoided, even if the jewelry clasp is opened involuntarily.

Abstract: ABSTRACT        An apparatus for winding a web of material comprises a driven supporting roller a winding reel is supported during the winding operation and pressure rollers that can be pressed against the periphery of a winding reel, the pressure rollers being mounted in pairs parallel to the axis of the supporting roller at the end of an upwardly pivotable lever fastened at the side of the supporting roller.  The axes of rotation of the pairs of rollers are movably mounted on the associated pivoted lever about an axis approximately parallel to the longitudinal direction of the pivoted lever.  This is achieved by making the pivoted lever of two mutually movable parts interconnected by a spring so that the length of the lever decreases automatically under the weight of the lever against the spring as the lever pivots to a more vertical position.  The invention provides a uniform line pressure even when the winding reels are not wound exactly cylindrically.

Title: Process for the separation of amines
Inventor: FLORK MICHEL
IPC: B01J47/02
Filed: 1988-06-13
Granted: 1995-02-14
Abstract: In a process for separating aminoacids from a mixture containing them using non-exchange resins, the mixture is passed successively over several columns arranged in series and filled respectively with an absorptive material, a first ion-exchange resin, and a second resin which exchanges oppositely-charged ions. Preferably the mixture is passed at least once succesively over the same two columns of anion and cation-exchange resins. Each column can be previously oxidized by an oxidizing agent. This process permits a high degree of separation of a complex mixture of amino acids derived, in particular, from the hydrolysis of proteins without the addition of external agents.
