Abstract: ABSTRACT OF THE DISCLOSURE         An automatic wrapping machine includes a turntable for holding a load positioned adjacent a film support which dispenses a roll of stretchable film, a brake for tensioning and stretch-ing the film, a clamp on the turntable adjacent the load to hold the film while the turntable and load rotate, allowing the film to wrap the load.  The clamp releases the film after completion of at least one revolution and withdraws from the film.  A film cutter adjacent the turntable cuts the film after the load is wrapped, clamps the free end of the film in a secured position and positions the film web for engagement by the turntable clamp to hold it for the wrapping of the next load.  The cutter has a pair of cooperating aligned jaws pivotally mounted for hori-zontal travel which allow the load to freely rotate when they are in a first position and engage the film in a second position to cut and clamp it near one side of the load after the load is wrapped.  One of the jaws has a film cutting blade mounted next to a film clamping pad member.  The other jaw has a substan-tially "U" shaped cross-section made up of two operative edges so that when the jaws close, one operative edge draws the film web into a cutting position and the other operative edge en-gages the pad member to clamp the film, the two operative edges providing a captive space between which the film cutting blade can sever the film.

Title: Mold for the casting of resin ophthalmic  lenses having a prismatic segment
Inventor: CAMPBELL CHARLES D
Filed: 1979-07-27
Granted: 1981-12-01
Abstract: ABSTRACT     A mold for casting a resin ophthalmic lens is comprised of a glass disc defining a principal casting surface on one face thereof.  The casting surface is a portion of a surface of revolution which has a first axis of symmetry and which has, at a location along such axis, an effective center of curvature.  The principal casting surface has, in a selected portion thereof, a bottom surface defining in the mold a minor casting surface which is a portion of a surface of revolution having a second axis of symmetry.  The first and second axes, if they intersect at all, intersect at a location on the first axis other than at substantially the center of curvature of the principal casting surface.     The mold is made by forming in one face of a first glass blank an optically finished surface which has a curvature identical to that of the bottom surface of the mold recess.  A second glass blank is provided, and has characteristics sufficiently compatible with those of the first blank that the first and second blanks may be stably adhered together.  The second blank, as initially provided, has formed at least partially therethrough a recess which has a perimetral shape at least partially congruent to the perimetral shape of the mold recess.          The mold making procedure includes forming in one side of the second blank a second surface which is essentially reversely curved to that of the finished surface in the first blank.  The second surface is formed on the second blank so that, upon completion of the second surface, the recess extends through the second blank.  The first and second blanks are registered with each other with the formed surfaces thereof in opposition.  The registered blanks are adhered together to define a resulting blank. The mold making procedure further includes forming in the face of the resulting blank to which the recess opens an optically finished third surface having a curvature identical to the curvature of the mold principal casting surface; this step is performed without eliminating the recess entirely from the resulting blank.

Abstract: ABSTRACT This method of making 5, 6-dihydro-2-methyl-N-phenyl-1,4-oxathiin-3-carboxamide is based on the use of an oxathiolane, namely, 2-methyl-N-phenyl-1,3-oxathiolane-2-acetamide, which may be formed by condensing 2-mercaptoethanol with acetoacetanilide under acidic conditions in a solvent medium (aromatic hydrocarbon, chlorinated hydrocarbon or alkyl ester of an aliphatic acid). The said oxathiolane, with or without purification, is reacted with hy-drogen peroxide in water or in a water-organic solvent mixture under hasic conditions in the presence of a catalytic amount of a metal compound such as sodium tungstate to form 2-methyl-N-phenyl-1,3-oxathiolane-2-acetamide 3-oxide. The said oxathiolane oxide, while dissolved in a chlorinated hydrocarbon or an alkyl ester of an aliphatic carboxylic acid, or while suspended in an aromatic hydrocarbon, is subjected to a ring expansion reaction by heating under acidic conditions in the presence of a catalytic quan-tity of a sulfonium, sulfoxonium or pho;,phonium compound, to form 5, 6-dihydro-2-methyl-N-phenyl-1, 4-oxathiin-3-carboxamide     with evolution of water. The product is a known bactericide and fungi-cide.
