Patents by Inventor Irving O'Strander

Irving O'Strander has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8276654
    Abstract: A heat exchanger assembly includes a core assembly having air passages that are closed off on at least one side by a closure bar. A reinforcing bar is received within a channel of the closure bar to create an interface with substantially no gaps that may accumulate moisture within the core assembly. The prevention of moisture accumulation at the interface between the reinforcing bar and the closure bar prevents potential damage caused by freezing.
    Type: Grant
    Filed: November 17, 2005
    Date of Patent: October 2, 2012
    Assignee: Hamilton Sundstrand Corporation

  • Patent number: 8136384
    Abstract: A hardband wear testing system with a first rotatable member connected to a tool joint to rotate the tool joint in a first direction. A second rotatable member connectable to the casing sample to rotate the casing sample in the first direction or in a second direction opposite to the first direction. One or more actuators may be utilized to raise and lower the second rotatable member and the casing sample with respect to the tool joint.

  • Publication number: 20020058164
    Abstract: Embodiments provide methods for the protection and consolidation of calcareous materials. An exemplary method includes providing an aqueous solution of a hydroxycarboxylic acid, adjusting the pH of the aqueous solution by adding an alkaline agent, and applying the pH-adjusted aqueous solution to a calcareous mineral to form a conversion layer on the mineral. The calcareous mineral may, for example, be carbonate rock, particularly limestone and marble, or may be part of masonry material, aggregates, or fillers. Adherent conversion layers are readily formed at ambient temperatures and, therefore, methods provided are suitable for field application. Conversion layers so formed are provided as further embodiments.
