Patent number: 10000289Abstract: A temperature control gasper apparatus for vehicle interiors such as aircraft cabins. Airflow temperature, volume and orientation are integrated and controlled by the gasper apparatus—at the point of use of the gasper apparatus. The temperature control gasper apparatus includes a mixing chamber, a temperature control dial, and an airflow control nozzle assembly. The temperature control gasper apparatus provides airflow output control with rotation of a grip member of the nozzle assembly relative to a ball portion of the mixing chamber, temperature control by rotation of a handle portion of the temperature control dial relative to the ball portion of the mixing chamber, and airflow direction control by movement of the ball portion of the mixing chamber relative to a socket portion of the mixing chamber fixed to the vehicle interior.Type: GrantFiled: February 2, 2012Date of Patent: June 19, 2018Assignee: Senior IP GmbHInventors: Leslie Fernandes, Charlie Rann, Krist Khodjasaryan

Publication number: 20160195207Abstract: A flexible high pressure ball joint for a pressurized fluid line has an outer annulus, an inner annulus, and a flexible bellows connecting a first conduit to the second conduit. The joint further includes a toroidal bearing disposed about the inner annulus and engaged at a shoulder, and a cover extending over the toroidal bearing. To reduce galling, an insert having an arcuate portion conforming to an outer surface of the toroidal bearing is disposed between said toroidal bearing and the cover.Type: ApplicationFiled: December 29, 2015Publication date: July 7, 2016Inventor: Leslie Fernandes

Patent number: 9205402Abstract: A system for removing oxygen molecules and ozone molecules from an airstream includes a dual core ozone converter having a first core and a second core separated by a gap G, and an air separation module for extracting oxygen molecules (O2) from the airstream, wherein the dual core ozone converter increases the oxygen concentration by removing the ozone present in the airstream, and the air separation module extracts the oxygen from the airflow exiting the dual core ozone converter.Type: GrantFiled: June 3, 2015Date of Patent: December 8, 2015Assignee: RSA Engineered Products, LLCInventors: Leslie Fernandes, Arnaud Amy

Patent number: 8967185Abstract: A leak detector for an insulated duct carrying pressurized hot air comprises a cover secured over a circumferential cut in the insulation of the duct, or over a joint connecting duct sections, thereby creating a reservoir of hot air which has leaked from the duct or joint, a manifold block defining a conduit therein in communication with the hot air reservoir and a cap for securing heat sensitive wires to manifold at the end of the conduit such that the hot air from the hot air reservoir impinges directly on the heat sensitive wires. The leak detector includes flow control mechanisms in the body of the manifold block, to prevent false alarms arising from nominal leakage resulting from ordinary operation of the duct system.Type: GrantFiled: July 21, 2010Date of Patent: March 3, 2015Assignee: Senior IP GmbHInventors: Leslie Fernandes, Arnaud Amy

Patent number: 8454056Abstract: A clamp apparatus for holding together two abutting pipe ends, in which the pipe ends have radial flanges to facilitate the exerting of axial compressive forces on the pipe ends. The clamp includes a first strap structure and a fastening mechanism for providing circumferential compressive force on retainer segments configured to transfer the compressive force onto the flanges of the pipe ends. The clamp apparatus also includes a secondary strap structure for providing independent redundancy, relative to the primary strap, to supply back-up circumferential force onto the primary strap structure, should a failure occur in either of the fastening mechanism or the primary strap structure, to enable the clamp to maintain clamping force on the abutting pipe ends.Type: GrantFiled: July 28, 2011Date of Patent: June 4, 2013Assignee: Senior Investments GmbHInventors: Leslie Fernandes, Charlie Rann

Patent number: 5697651Abstract: Disclosed is a flexible joint for sealing two conduits. One half of the joint includes an annular seal gland with an outer surface defining a static seal face. The other half of the joint includes an inner race member having inner and outer bearing surfaces, the inner surface spaced apart from and generally opposing the outer surface of the seal gland and having a region defining a dynamic seal face. An annular bellows constructed of a plurality of convolutions having varying convolution heights is disposed between the first and second seal faces to form a low leakage seal. The heights of the convolutions decrease in the direction of the first to the second seal faces.Type: GrantFiled: March 2, 1995Date of Patent: December 16, 1997Assignee: Senior Flexonics, Inc.Inventor: Leslie Fernandes
