Malloy, Elmira Heights, N.Y., and Charles Thomas, Athens, Pa., for a "center conductor terminal having increased contact resistance." The abstract of the patent published by the U.S. Patent and Trademark Office states: "A terminal assembly is provided for terminating a center conductor of a coaxial cable. The terminal assembly includes a terminal body having a pin at one end and a cavity at the other end for accommodating a center conductor therein. A contact member is supported within the cavity. The contact member includes plural inwardly directed cantilevered beams extending from a contact base for deflectable engagement with the inserted center conductor. The terminal body includes an inwardly directed shoulder for engagement with the beams at a location between the base and the distal ends of the beams. The location defines a deflection fulcrum at a location distal from the base so as to provide increased contact engagement force between the distal ends of the beams and the center conductor." The patent application was filed on Dec. 13, 2011 (13/324,664).

Schweikert, Levittown, Pa., for a "gastric inflation band with integrated infusion catheter." The abstract of the patent published by the U.S. Patent and Trademark Office states: "An inflatable gastric band incorporates a fluid channel within an outer surface of the band and an inflatable bladder on a stomach-facing side of the band. The gastric band attaches to a double lumen catheter, which communicates with a dual infusion port. One lumen communicates with the fluid channel and one port, while the other lumen communicates with the inflatable bladder and a second port. Injection of fluid into one chamber of the infusion port expands inflatable bladder, allowing adjustment to the diameter of the stoma. Injection of drugs or therapeutic agents into the second chamber allows the infusion of drugs or agents directly into the abdominal cavity of a gastric band recipient. The inflatable bladder can be continuous or segmented. A segmented bladder reduces pinching and/or folding of the inner surface of the gastric band during expansion/contraction, thereby lessening stomach pinching and/or irritation." The patent application was filed on Jan. 30, 2009 (12/362,680).

The co-inventors are Chris A. Wright, Bordentown, N.J., Glen B. Brons, Phillipsburg, N.J., Sharon Feiller, Allentown, Pa., and George A. Lutz, Brick, N.J. The abstract of the patent published by the U.S. Patent and Trademark Office states: "Non-high solvency dispersive power (non-HSDP) crude oil with increased fouling mitigation and on-line cleaning effects includes a base non-HSDP crude oil and an effective amount of resins isolated from a high solvency dispersive power (HSDP) crude oil, and method of making same. Also, methods of using such non-HSDP crude oil for on-line cleaning of a fouled crude oil refinery component, for reducing fouling in a crude oil refinery component, and in a system capable of experiencing fouling conditions associated with particulate or asphaltene fouling."
