Pratt & Whitney's F135 engine used in the Joint Strike Fighter, an aircraft that can take off and land vertically, has passed a testing milestone known as initial service release.Hamilton Sundstrand Corporation has selected TTTech to support the development of a TTP-based data communication platform for use in Hamilton Sundstrand’s electric and environmental control systems on the Boeing 787 Dreamliner.The purchase of the plant in Wrocław, first announced in September, was finalized at the end of December and announced this month by the Polish embassy in Washington. Polish journalists said that the company, PZL, has had financial problems for two years, but that the acquisition by the United Technologies Corp.A Plainville aerospace manufacturer that sells precision metal parts to Sikorsky, Hamilton Sundstrand and others is hoping to build a 14,000-square-foot addition, beginning in April.The company was formed from the merger of Hamilton Standard and Sundstrand Corporation in 1999.
For the fourth straight year, United Technologies Corp.On June 10, 1999, Hamilton Standard and the Sundstrand Corp. Hamilton Sundstrand traces its roots to the founding of the Sundstrand Corp. In early 2001, Claverham Ltd was sold to Hamilton Sundstrand.On 2 January 2008, Hamilton Sundstrand announced it would commercialize the concentrated solar power tower technology and corresponding molten salt storage system developed by Rocketdyne through a new entity known as Solar Reserve. Schulman, Lee Ann Stevenson and Vickie Reznik, of New York, NY. Opinion dissenting in part filed by Circuit Judge NEWMAN. The broader original independent claims were cancelled. To do this it is necessary to determine when and how far to open the surge bleed valve in order to maintain a level of flow sufficient to avoid surge. The set point is compared to a "flow-related parameter" that represents airflow out of the compressor as determined by a sensor. The '893 and '194 patents resulted from a common application filed February 19, 1981. Only claims 8, 10, 11, 19 and 23 of the '893 patent and claim 4 of the '194 patent are at issue in this case. It rejected Honeywell's contention that Sundstrand had literally infringed the '194 patent, but found claims 8, 10, 11, 19 and 23 of the '893 patent and claim 4 of the '194 patent infringed under the doctrine of equivalents. Opinion for the court filed by Circuit Judge DYK, in which Chief Judge MAYER and Circuit Judges MICHEL, LOURIE, CLEVENGER, RADER, SCHALL, BRYSON, GAJARSA, LINN, and PROST join. 4,380,893 (the "'893 patent") and claim 4 of Patent No. All of the asserted independent claims were originally dependent claims that were rewritten into their present independent form during prosecution. The Honeywell APU is designed to be more efficient by avoiding excess air bleeding in its control of surge. If the system determines that airflow out of the main air duct is too low, the surge bleed valve will be opened to prevent the build up of excess pressure leading to surge. The jury found that all of the asserted claims of the '893 and '194 patents were not invalid. This cooperation between Hamilton Sundstrand and TTTech is expected to continue as a productive long-term partnership for both companies.
