Abstract: HILTON FOOTE                    "COMBINATION CONNECTOR"     ABSTRACT     This combination connector and plug is for use in a sap collecting system in which plastic tubing is connected to a spout inserted in a borehole in the trunk of a tree.  A member has an axial passageway for transporting sap between a first fitting for connecting a first plastic tube to the member and a second fitting for connecting a second plastic tube to the member.  A projection extends from the member and is dimensioned to fit in sealing engagement in the end of the spout when the spout is removed from the borehole.  With the projection placed in the end of the spout, the plastic tubing connector and spout can be stored by hanging them in a sealed condition on one of the trees from which the sap is collected.

Abstract: ABSTRACT OF THE DISCLOSURE      A process is disclosed for treating a fluid-permeable hydrocarbonaceous solid, such as coal, containing an admixture of hydrocarbonaceous components and mineral and sulfur com-ponents,  to  separate  the  solid  into  a  hydrocarbonaceous enriched fraction and a mineral and sulfur enriched fraction.          The process involves comminuting the solid in the presence of a low molecular weight alcohol under conditions sufficient to substantially scission the hydrocarbonaceous components from the mineral and sulfur components and to selectively comminute the hydrocarbonaceous components.   The resultant product is thereafter  separated  into  the  enriched  hydrocarbonaceous fraction and the enriched mineral and sulfur fraction.    In a preferred embodiment of the process, the hydrocar-bonaceous solid is mixed with a low molecular weight alcohol, such as methanol, to form a slurry.  The slurry is then heated and  pressurized  to  a  temperature  and  pressure  above  the critical  temperature  and  pressure  of  the  alcohol.    In particularly  preferred  form,  the  slurry  is  heated  for  a sufficient length of time to form: (1) a dissolved portion of the  hydrocarbonaceous  components  in  alcohol;  (2)  an  un-dissolved  suspended  portion  of  hydrocarbonaceous material saturated with the alcohol; and  (3)  a discrete undissolved suspended portion of the mineral components.  The superheated slurry is thereafter expanded, preferably by a substantially instantaneous  adiabatic  expansion,  most preferably  in  the presence of a sulfur scavenger compound.   The result is a selective  precipitation,  comminution  and  production  of substantially  mineral  and  sulfur  free,  ultra-fine  hydro-carbonaceous particles in admixture with discrete relatively larger mineral particles.     The hydrocarbonaceous particles of the resultant product are separable into an enriched hydrocarbonaceous fraction in which between about 70 and about 95 percent by weight of the mineral components and about 80 to 100 percent of the organic sulfur components have been removed.   The hydrocarbonaceous particles of the enriched hydrocarbonaceous fraction have a mean  volumetric  diameter  of  less  than  about  5  microns, preferably  less than about  3  microns  and most preferably between about 1 and 0.1 microns. The product stream is further  separable into a fluid stream comprising alcohol and other light hydrocarbons with small particles of combustible coal derivatives and substan-tially without mineral or sulfur compounds.  This fluid stream can be condensed or converted into a clean fuel suitable for use in transportation vehicles.

Abstract: CERAMIC STOVE              ABSTRACT OF DISCLOSURE      A ceramic stove that may be supplied in kit form includes a base frame, a cast iron firebox secured on the base frame, a top frame attached to and surrounding the top of the firebox, and ceramic panels extending between and held by the frames in spaced relation from the firebox.  The ceramic panels are "ship-lapped" relative to each other and are not cemented or otherwise positively attached to each other.  Logs may be fed as fuel into the fire box door from one side of the stove allowing longer logs to be burned.  The logs rest on a grate which includes a "shakable" portion for shaking ashes onto an ash pan located below the grate.  A separate, small door into the firebox is provided for starting the fire and that door is covered by another, safety door which also closes the space through which the ash pan is removed for emptying.  An outer screen gate is provided to overlie the firebox doors and the entire side of the firebox.  Products of combustion rise in the firebox and are guided by a baffle in a desired serpentine path prolonging their containment, until they reach an outlet at the top of the fire box where they are then carried downwardly by a flue formed in part by a portion of the back wall of the firebox.  A heat shield covers the back wall of the firebox including the flue whose outlet extends through the heat shield at mid elevation.          Other features and advantages are also disclosed.

Abstract: ABSTRACT             PROTECTION AGAINST DENTAL CARIES         An antigenic protein, termed antigen C, present on the cell wall and in cultures of Streptococcus mutans, espe-cially genetic group I (serotypes c, e and f) is separated from other antigenic proteins, notably those which cross react with heart tissue, to give an antigen preparation which may be used as a vaccine or to raise antibodies for use in protec-ting against dental caries.  Antigen C is destroyed or extracted from the cell walls by treatment with boiling aqueous sodium dodecyl sulphate (10 gm per litre) for 10 minutes.  It has a molecular weight of 70,000 ? 5,000 and an isoelectric point of 4.45 ? 0.24.  It is destroyed by proteolytic enzyme and does not cross react with heart tissue.  The antigen also occurs in the culture filtrate and/or cell extract and may readily be separated from these sources by affinity chromatography on immobilised antibody.
