Abstract: ABSTRACT OF THE DISCLOSURE               A temperature responsive valve is disclosed including a pair of body members which are snapped together and when assembled define a valve chamber.  Located within the valve chamber is a bimetal snap disc which seats at its periphery against an O-ring type valve seat when in one position of stability and is spaced from the valve seat in its other position of stability.  A spider type spring extends between the cover member and the center of the disc to urge the disc in a direction toward the valve seat.  The spring is provided with depending tabs which are positioned adjacent to the side wall of the cavity and function to insure proper location of the spring during assembly of the cover member.  The tabs also function to insure proper position of the disc during the operation of the valve.

Abstract: ABSTRACT OF THE DISCLOSURE           A novel crystalline silica composition having uniform pore dimensions of approximately 6 Angstrom units is prepared by calcining a crystalline hydrated alkylonium silicate prepared hydrothermally from a reaction mixture containing as essential reagents, water, amorphous silica and a quaternary ammonium compound at a pH of at least 10.        The crystalline silica, because of its uniform pore structure, is capable of making size-selective separations of molecular species, but neither it nor its silicate precursor exhibit ion-exchange properties.           This absorbent has a very useful hydrophobic/ organophilic characteristic which permits its use in selectively adsorbing organic materials from water, either in liquid or vapor phase.

Abstract: Abstract of Disclosure An incinerator system and method wherein pieces of solid waste, such as fragments of wood, are disposed within a fluidized bed of an incinerator vessel, preferably the solid waste particles homogeneously.  The fluidized bed is situated above a high temperature air delivery chamber at the bottom of the vessel and supports combustion or gasification of the solid waste particles in the fine granular material, preferably olivine, comprising the fluidized bed.  Volatile matter given off by combustion is burned smokelessly in the vapor space immediately above the bed.  All air flow is vortical being caused at least in part by the heat of the bed.  Thus, fine particles comprising the bed and small pieces of solid waste are centrifuged back to the bed.  Any solid waste retained within the vapor space are ultimately consumed.          Special bed nozzles to which air is selectively channeled aids in improved combustion by defining a region in which tramp material is either trapped and stored, or trapped and removed.  A novel fluidizing air system comprising parallel, spaced air ducts, creating uniform air distribution and nozzle discharge, accommodates continuous recirculation and purification of bed material during normal burner operation is provided.

Abstract: CONDENSER HEADER CONSTRUCTION     Abstract of the Disclosure There is disclosed herein an improved multipass condenser construction having provisions therein which allow the condensate formed from each pass through the core portion thereof to by-pass substantially all of the remaining core portions thereby promoting maximum efficiency of the condenser. The condenser comprises a pair of vertically extending headers each having a plurality of baffles provided therein and an interconnecting core structure. The baffles are arranged so as to cause a gaseous fluid to flow through the core structure in alternating directions so as to be cooled and condensed to a liquid state. Each of the baffles is provided with a small aperture which allows condensate formed from each pass of the gaseous fluid through the core structure to by-pass the remaining portions of the core and flow directly to the lower end of the headers. Also, in that the volume of fluid to be passed through the core structure is constantly being reduced due to the separation of the condensate and the cooling of the gaseous fluid, successively fewer fluid conducting members are provided for successive flow paths while still maintaining the same overall flow capacity for the condenser unit.

Abstract: TITLE          AUTOMATIC RESAW SHAKE CUTTER AND METHOD      ABSTRACT OF THE DISCLOSURE           A plurality of rows of vertically spaced discs are located on opposite sides of the path of movement of a shake blank as it is pushed along a cutting plane into the path of a bandsaw blade.  The discs on each side of the cutting plane have respective radii either uniformly progressively increasing for a portion of their perimeters or uniformly progressively decreasing for a portion of their perimeters so that as the discs rotate they engage opposite side faces of the blank, advancing the blank in the cutting path and simultaneously skew the rearward end of the shake laterally of the cutting plane so that the shake blank is cut along a diagonal.  The framework supporting all of the discs can be moved to simultaneously shift all discs laterally to accommodate cutting characteristics of a particular saw blade.  Initial positioning of the forward end and final positioning of the rearward end of the blank for overly thick blanks is obtained by cam surfaces on the two rows of discs closest upstream of the blade.  The blank is positioned at its forward end so that its side surface is generally in alignment with the cutting plane and as the blade is nearing the rearward edge of the blank the opposite side face of the blank is moved positively into the cutting plane.

Abstract: ABSTRACT     The present invention relates to a viscoelastic gel particularly suitable for use in electrodes for medical purposes.          Thus it is desirable to provide a contact agent which exhibits a generally resistance free transfer of electric current even after an extended time of application and would leave no residues on the skin or give rise to other undesired reactions on the skin.  Moreover, the electrodes provided with such agent require only a simple manufacturing technology resulting in a low cost in order to make it possible to use the electrode as a single application article.  The specification discloses an electrically conductive, viscoelastic gel containing, relative to the total weight of the substance, 10-50 wt.% of a high molecular weight polysaccharide; 90-20 wt.% of one or more polyols containing 5-50 wt.%, preferably 10-20 wt.% of water, 0-30 wt.% of one or more non-volatile acids soluble in the polyol, 0-30 wt.% of one or more non-volatile bases, soluble in the polyol and, where desired, a small volume of suitable additives or agents.
