Patent number: 9259859Abstract: A method for shaping dry preform material prior to resin infusion is disclosed. The starting material to be shaped is a preform blank (e.g. flat sheet) of dry, fibrous material. The shaping process is a vacuum forming process that relies on controlling the vacuum pressure and deformation speed to produce a shaped preform with three-dimensional configuration. The purpose of the shaping process described herein is to enable an automated process to replace the conventional hand lay-up operation.Type: GrantFiled: December 19, 2013Date of Patent: February 16, 2016Assignee: Cytec Industries Inc.Inventors: Robert Blackburn, James Eastbury, Samuel Hill

Publication number: 20150375461Abstract: A dry, fibrous tape for use in an automated placement process such as ATL or AFP and a preform produced therefrom. The preform is configured for resin infusion. The tape contains a layer of unidirectional fibers, at least one nonwoven veil bonded to one side of the fiber layer, and at least binding materials present within the tape. The preform produced from laying down such tape exhibits a low-bulk property that is close to the final thickness of the cured fiber-reinforced resin article and no further consolidation or compaction is required.Type: ApplicationFiled: June 25, 2015Publication date: December 31, 2015Applicant: Cytec Industries Inc.Inventors: Robert Blackburn, Samuel Jestyn Hill, Dominique Ponsolle, Carmelo Luca Restuccia

Patent number: 8990821Abstract: A method and system is disclosed for dispatching tasks to multiple processors that all share a shared memory. A composite queue size for multiple work queues each having an associated processor is determined. A queue availability flag is stored in shared memory for each processor work queue and is set based upon the composite queue size and the size of the work queue for that processor. Each queue availability flag indicates availability or unavailability of the work queue to accept new tasks. A task is placed in a selected work queue based on that work queue having an associated queue availability flag indicating availability to accept new tasks. The data associated with task dispatching is maintained so as to increase the likelihood that valid copies of the data remain present in each processor's local cache without requiring updating do to their being changed by other processors.Type: GrantFiled: September 29, 2009Date of Patent: March 24, 2015Assignee: International Business Machines CorporationInventors: Robert A.

Publication number: 20140222303Abstract: A method for controlling a dump body of a hauling machine wherein the hauling machine includes an engine, at least one extendable cylinder, a lift energy source, and a controller is provided. The method includes initiation of the dump operation, detection of payload from the payload signal, calculation of engine throttle based on the payload information, and detection of machine speed based on the machine speed signal. Upon detection of machine speed, if the machine speed coincides with the first selective dump command, the transmission is disengaged and the payload is released at selective dump angle. If the machine speed coincides with the second selective dump command, the payload is released at selective dump angle.Type: ApplicationFiled: April 4, 2014Publication date: August 7, 2014Applicant: Caterpillar S.A.R.L.Inventors: BADRI NARAYANAN CHARY, MARK ROBERT BLACKBURN

Patent number: 8413161Abstract: A method and system is disclosed for selecting a work queue associated with a processor within a multiple processor architecture to assign a new task. A local and a remote queue availability flag is maintained to indicate a relative size of work queues, in relationship to a mean queue size, for each processor in a multiple processor architecture. In determining to which processor to assign a task, the processor evaluates its own queue size by examining its local queue availability flag and evaluates other processor's queue sizes by examining their remote queue availability flags. The local queue availability flags are maintained asynchronously from task assignment. Remote flags are maintained at time of task assignment. The presented algorithm provides improved local processor queue size determinations in systems where task distribution processes execute with lower priorities that other tasks.Type: GrantFiled: September 29, 2009Date of Patent: April 2, 2013Assignee: International Business Machines CorporationInventors: Robert A.
