Publication number: 20230063848Abstract: In a door latch for a hinged or pivoting door having a latch fixture mounted in or on the door that supports a slideable bolt that is magnetically attracted to a fixed strike so as to effect latching action by extension of the bolt, a safety catch mechanism which, while engaged, prevents the bolt from extending, the safety catch mechanism having a catch member that operatively acts between the moveable bolt and the latch fixture, and an operating mechanism to operate the catch member responsive to magnetic forces from the strike. First and second actuators are disposed to opposite sides of the door, each of the first and second actuators being coupled to the latching mechanism to effect withdrawal of the latch bolt from its extended position to its retracted position upon operation by a user. A privacy lock mechanism is operable from one side of the door only and can be used to prevent the actuator on the other side of the door from operating the latch.Type: ApplicationFiled: August 24, 2022Publication date: March 2, 2023Inventors: Dean Beardmore, Bryan Marshall, Zac Hanna

Patent number: 11014655Abstract: A system and method for providing supplemental power includes: a motor-generator or a hydraulic pump-motor configured to attach to a transmission of an engine, a controller connected to the motor-generator or the hydraulic pump-motor, and a battery system or a hydraulic accumulator coupled to the motor-generator or the hydraulic pump-motor, respectively. During normal operation of the engine, the engine drives the transmission to rotate rotor blades connected to the transmission, and the motor-generator or the hydraulic pump-motor draws an energy from the transmission and store the energy in the battery system or the hydraulic accumulator, respectively. Upon a manual and/or an automatic control by the controller, the battery system or the hydraulic accumulator discharges the energy to the motor-generator or the hydraulic pump-motor, respectively, and the motor-generator or the hydraulic pump-motor provides the supplemental power to drive the transmission to rotate the rotor blades.Type: GrantFiled: August 14, 2018Date of Patent: May 25, 2021Assignee: BELL HELICOPTER TEXTRON INC.Inventors: Dudley E.

Patent number: 10322798Abstract: A rotor yoke manufactured by a process comprising preparing a molded rotor yoke in a closed cavity tool and possibly machining at least one portion of the molded rotor yoke to form the rotor yoke. In the preferred embodiment, the preparing of the molded rotor yoke is accomplished by applying layers of uncured low-flow composite material and a layer of uncured high-flow adhesive; substantially enclosing the uncured molded rotor yoke in the closed cavity tool; and applying pressure so as to compress the uncured molded rotor yoke; and curing the uncured molded rotor yoke. During the curing process, the high-flow adhesive bleeds out of the molded rotor yoke, thereby preventing marcels from forming through movement of the low-flow composite material.Type: GrantFiled: December 1, 2015Date of Patent: June 18, 2019Assignee: Textron Innovations Inc.Inventors: Frank B.
