Patent number: 11760844Abstract: Disclosed are latexes, suspensions, and colloids having a cationic antimicrobial compound complexed with an anionic surfactant. The surfactant may have greater affinity for the antimicrobial compound than other anionic surfactants and other anions in the latex, suspension, or colloid that contribute to disperse phase stability to prevent disrupting the dispersions. Dispersions containing the antimicrobial compound may therefore have a shelf life comparable to dispersions that are otherwise identical but lack the cationic antimicrobial compound and its complexed anionic surfactant. Coatings made with the complexes can exhibit essentially undiminished antimicrobial activity.Type: GrantFiled: July 15, 2022Date of Patent: September 19, 2023Assignee: Poly Group LLCInventors: Thomas E. Hopkins, Craig A. Kalmer

Publication number: 20230265225Abstract: Polycationic polymeric antimicrobial surfactant and polymeric biocompatible antimicrobial surfactant compositions are useful in dispersing various compounds in a carrier liquid. The polycationic polymeric antimicrobial surfactant and polymeric biocompatible antimicrobial surfactant compositions employ polymers having both hydrophilic domains and hydrophobic domains so that the compositions can disperse particles such as polymer particles or droplets in a continuous phase as well as provide stable dispersions that have not been provided before. The antimicrobial properties of the compositions provide much-needed capabilities of fighting infectious agents such as bacteria and viruses in a wide spectrum of products such as paint, adhesives, and coatings. Methods of using these compositions as well as methods of making products using the compositions are disclosed.Type: ApplicationFiled: April 29, 2023Publication date: August 24, 2023Inventors: Thomas E.

Patent number: 7268098Abstract: A thermally printable commercially functional cash register tape produced from a thin oriented, heat stabilized, thermoplastic film is described. This thermoplastic tape replaces the currently used paper cash register tape. It will accept printing, has sufficient machine direction stiffness and sufficiently reduced surface electrical charges to function in conventional commercial cash register printers. The thermoplastic tape is much thinner than the conventional paper tape so a roll of the plastic register tape contains about 4.7 times the paper length of a typical cash register roll.Type: GrantFiled: November 28, 2005Date of Patent: September 11, 2007Inventor: Thomas E. Hopkins

Publication number: 20030065296Abstract: An absorbent material is disclosed, containing at least about 30 weight percent of a superabsorbent polymer, a thermoplastic polymer binder resin, and about 0.1 to about 10 weight percent water. The absorbent material absorbs deionized water to at least about 70 percent of maximum capacity within about 20 minutes after exposure to the deionized water. The method of making the absorbent material includes combining binder resin and absorbent polymer in a twin screw extrusion mechanism, compounding and driving the composition toward exit openings, extruding the composition through the exit openings, and preferably rapidly cooling the extrudate with non-liquid quenching means. The quenched or non-quenched extrudate may be made in the form of a pellet, film, or fibrous strand.Type: ApplicationFiled: February 26, 2001Publication date: April 3, 2003Inventors: Thomas A.

Patent number: 4197984Abstract: A composite envelope prepared from a multiple panel blank which is folded twice in overlapping relationship to produce a tab portion and a detachable envelope portion. The panels are glued together to form the tab portion and the envelope portion, with a perforation line separating the two. The envelope includes a removable section and a flap containing remoistening glue for sealing the envelope.Type: GrantFiled: October 23, 1978Date of Patent: April 15, 1980Assignee: Dittler Brothers, Inc.Inventors: Robert Hartman, Thomas E.
