Patent number: 8481283Abstract: A method is disclosed for reversing fixation-induced cross-linking in tissue specimens that have been preserved for histological examination. The method involves placing the fixed tissue in a liquid under elevated temperature and pressure conditions that are sufficient to reverse the fixation-induced cross-linking, restore antigenicity to proteins, and permit improved molecular and proteomic analysis of the preserved tissue specimen. Methods are also disclosed for processing tissues for histological examination under elevated pressure conditions that enhance the perfusion of liquid reagents into the tissue and reduce overall processing times.Type: GrantFiled: September 13, 2012Date of Patent: July 9, 2013Assignees: The United States of America as Represented by the Department of Veterans Affairs, The United States of America as Represented by the Secretary of Defense on behalf of the Armed Forces Institute of Pathology, American Registry of PathologyInventors: Timothy J. O'Leary, Jeffrey T. Mason, Carol B. Fowler, Robert E. Cunningham

Patent number: 7896326Abstract: An article, method, and kit for holding an object in place on a wall that include a jig with a support member and a platform member that is coupled to, and extends perpendicularly from, the support member. The support member has a top end including a portion adapted to be positioned behind a wall-facing surface of an object placed upon the platform member and an opening that is adapted to removably engage a coupling device on or in a wall such that the support member is disposed in a substantially vertical hanging position upon the wall. The jig may further include a brace member that forms a triangle by connecting a lower side of the platform member to the support member.Type: GrantFiled: July 3, 2007Date of Patent: March 1, 2011Inventor: Robert E. Cunningham

Patent number: 5041992Abstract: A system and method for interactive design of user manipulable graphic elements. A computer has display and stored tasks wherein the appearance of graphic elements and methods for their manipulation are defined. Each graphic element is defined by at least one figure specification, one mask specification and one map specification. An interactive display editor program defines specifications of said graphic elements. An interactive program editor program defines programming data and methods associated with said graphic elements. A display program uses the figure, map and mask specifications for assembling graphic elements upon the display and enabling user manipulation of said graphic elements.Type: GrantFiled: October 24, 1988Date of Patent: August 20, 1991Assignee: University of PittsburghInventors: Robert E.

Patent number: 4696986Abstract: It has been determined that 1,2,3-trialkoxybenzenes and 1,2,4-trialkoxybenzenes can be utilized in order to increase the vinyl content of polydienes which are prepared utilizing lithium catalyst systems. For instance, it has been determined that 1,2,3-trimethoxybenzene and 1,2,4-trimethoxybenzene are very strong modifiers for utilization in such polymerizations. The utilization of the trialkoxybenzene modifiers of the present invention is highly advantageous because they promote fast polymerization rates and can be used to produce polymers having high vinyl contents.Type: GrantFiled: August 12, 1986Date of Patent: September 29, 1987Assignee: The Goodyear Tire & Rubber CompanyInventors: Adel F. Halasa, Robert E. Cunningham

Patent number: 4517505Abstract: An object of the invention is to provide variable damping for resonant vibrations which may occur at different rotational speeds in the range of rpms in which a rotating machine is operated.A variable force damper in accordance with the invention includes a rotating mass (12) carried on a shaft (11) which is supported by a bearing (13) in a resilient cage (14). Cage (14) is attached to a support plate (15) whose rim extends into an annular groove in a housing (17).Variable damping is effected by tabs (18) of electrically conducting, non-magnetic material which extend radially from the cage (14). The tabs (18) at an index position lie between the pole faces of respective C-shaped magnets (19). The magnets (19) are attached by cantilever spring members (20) to the housing (17).By rotating the support plate (15) about the axis of shaft (11), the tabs (18) may be rotated through an angle 0 of about 40.degree. away from the index or 0.degree. position. At the 40.degree. position minimum damping is obtained.Type: GrantFiled: February 3, 1983Date of Patent: May 14, 1985Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventor: Robert E.
