  • Passive fail safe coupling mechanism
    Patent number: 9422053
    Abstract: A ground propulsion assembly for an aircraft includes an axle, a wheel rotatably connected to the axle, and a transmission. The transmission includes a housing mounted proximate the axle and a drive element disposed at least partially outside of the housing and operatively connected to a power input. A mounting bar extends between the axle and the transmission and a mounting bar first end is rigidly connected to the axle, and the transmission is pivotally connected to a mounting bar second end. A spring is disposed between the transmission and the axle and the spring is configured to urge the drive element out of engagement with the wheel. An actuator is operatively connected between the transmission and the axle, and is configured to selectively generate a force in opposition to the disengagement spring such that the drive element moves relative the wheel and operatively engages the wheel.

  • Additive manufacturing of a component having a laminated stack of layers
    Patent number: 9419502
    Abstract: A method of making a component comprises producing a layer of sheet material including an aperture over a movable support. An insulating material is deposited in a first portion of the aperture to form an insulating coating with one or more pockets. A conductive material is deposited in the one or more pockets.

  • Pipette tip, pipette device, and combination of pipette tip and pipette device
    Patent number: 9415388
    Abstract: A pipette device has a coupling stud on which a pipette tip can be stuck in a slipping-on direction for coupling. The coupling stud has an adjustable prestress member that can be adjusted into a prestress state and a release state via an actuation device which is provided in the coupling stud. The pipette tip has an axial stop which interacts with a counter-stop of the coupling stud in an axial coupling position of the pipette tip. The prestress member in its prestress state acts upon a working surface of the stuck-on pipette tip having a surface component of the pipette tip, which extends radially inward, turned away from the stuck on direction, in such a way that it abuts sealingly on the working surface, and prestresses the pipette tip on the pipette unit into the axial coupling position. The prestress member, in its releasing state, substantially releases the working surface of the pipette tip (101).

  • SYSTEM AND METHOD FOR ENHANCED ION PUMP LIFESPAN
    Publication number: 20160233063
    Abstract: Within an ion pump, accelerated ions leave the center portion of an anode tube due to the anode tube symmetry and the generally symmetrical electric fields present. The apparent symmetry within the anode tube may be altered by making the anode tube longitudinally segmented and applying independent voltages to each segment. The voltages on two adjacent segments may be time varying at different rates to achieve a rasterizing process. In various embodiments, one or more wire internal to the anode structure and having a time-varying electric potential may alter the trajectory of the ions leaving the anode tube, as may the shape of the anode near the ends of the anode tube.
