Abstract: PROCESS FOR PREPARING POLYGLYCEROL          Paul Seiden and James B. Martin Abstract of the Disclosure A process for preparing polyglycerol by heating glycerol under reduced pressure in the presence of a catalytic quantity of sulfuric acid and a low molecular weight glyceride until from about 25% to about 75% of the glycerol is polymerized.  The condensation is terminated by inactivat-ing the catalyst by adding a substantially stoichiometric amount of a suitable neutralizing agent.  Unreacted glycerol and cyclic diglycerol are removed by distillation.  The poly-glycerol so prepared can advantageously be employed in the preparation of polyglycerol fatty acid esters which are excellent food emulsifiers.

Abstract: ABSTRACT A process for protecting, preserving, and renewing surfaces, especially rubber and other natural and synthetic polymers, leather, wood, painted surfaces and metal, employs an aqueous emulsion of an unsubstituted or substituted dimethylpolysiloxane fluid, or mixtures thereof, to thoroughly wet the surfaces to be protected.  After a period of penetration, preferably about twenty four hours, the surface is rewetted and allowed to penetrate as in the first application.  At least one additional application and penetration gives optimum protection.  A preservative composition preferred for use in the above process is also provided.  In addition to a dimethylpoly-siloxane fluid aqueous emulsion as above described, this preservative also includes, based on the weight of the polysiloxane fluid, of from about 15% to about 65% by weight of one or more polyol compounds, preferably diethylene glycol and glycerin.

Granted: 1979-02-13
Abstract: ABSTRACT OF THE DISCLOSURE       A tool for testing the leak tightness of tube junctures is provided with an outer annular seal to seal the tool to a tube assembly.  The tool has a groove of variable width to permit significant radial expansion of the sealing gasket so as to extend radially beyond the tool outer surface in sealing engagement with an inner surface of the tube assembly being tested.  The extent of seal radial expansion permits passage of the tool in a contracted condition through a necked-down portion, for subsequent radial expansion of the tool into sealing engagement within a larger diameter portion of the tube assembly.  The construction of the tool permits insertion and removal of the tool as component parts, to facilitate operation and minimize likelihood of damage.

Abstract: ABSTRACT         An electrostatically actuated character generating display panel is disclosed.  The display panel embodies one or  more flexible membrane sections disposed in a predetermined pattern in an electric field generated between a transparent window and a closely spaced parallel support substrate.  By electrically charging the individual membrane sections, electrostatic forces are generated which displace the charged sections either ?? or away from the window.  The space between the window and the substrate is filled with a contrasting colored, high dielectric opaque fluid which normally occludes the membrane sections when they are displaced towards the substrate.  When the electrostatic forces displace the membrane sections against the window, the membrane displaces the opaque fluid and the contacting portion of the membrane section becomes visible through the window.  Selectively charging individual membrane sections in the pattern, indicative of the character to be formed, selectively displaces the charged membrane sections against the window and the desired character is visually formed. Alternatively, a message imprinted upon a single segment can similarly be made to appear or disappear.

Abstract: Abstract of the Disclosure A folding apparatus for laundry items such as sheets or the like employs a feed conveyor of continuous tapes or ribbons arranged at an incline.  The leading edge of the fed sheet drops by gravity from the upper conveyor end.  A blast from an adjacent air bar forces the longitudinal mid-point of the sheet to move onto a second conveyor substantially parallel to the feed conveyor and proceed toward the initial feed station whereat the once-folded sheet drops in front of a second air bar which forces the mid-point of such sheet onto a lower, third conveyor leading away from the feed station. The twice-folded sheet is then driven into the bite of pinch rolls disposed beneath the third conveyor and is folded twice more by buckle folders in the course of proceeding to a stacking means of simplified design.  The air bars instrumental in effecting the first two folds axe actuated by measuring means employed in combination with sheet-sensing means as will hereinafter be explained in greater detail.
