  • Breech mechanism sliding contact assembly
    Patent number: 8826794
    Abstract: A breech mechanism sliding contact assembly that allows for ignition, gun ground, and ammunition data link circuits to be broken while the breechblock is open. The sliding contact assembly further allows these circuits to be reconnected when the breechblock is closed. The breech mechanism sliding contact assembly comprises two separate connectors: a block slide connector that assembles to the breechblock and a ring slide connector that assembles to the breech ring. The two connectors operate in compact, pre-existing headspaces between the breechblock and the breech ring.

  • AXIAL THRUST CONTROL FOR ROTARY COMPRESSORS
    Publication number: 20140216081
    Abstract: Systems and methods are used to control operation of a rotary compressor of a refrigeration system to limit or prevent movement of rotors due to axial thrust loading resulting from rapid changes in speed of the rotors of the compressor. The operational profile of the motor is controlled to maintain acceleration torque and deceleration torque within predefined limits. The acceleration torque and deceleration torque are maintained within the predefined limits by controlling the speed of the motor, or by controlling the torque applied by the motor to the rotors during acceleration or deceleration.

  • VARIABLE APERTURE MECHANISM FOR USE IN VACUUM AND CRYOGENICALLY-COOLED ENVIRONMENTS
    Publication number: 20140061467
    Abstract: A variable aperture mechanism (VAM) comprises a cam assembly, a single motor capable of rotating the cam assembly, and a pair of aperture members which are coupled to the cam assembly and arranged to affect the size of an aperture, with the size of the aperture varying with the position of the cam assembly. The VAM would typically be used with a sensor having an associated optical field-of-view (FOV), with the aperture members moving in and out of the FOV with the rotation of the cam assembly such that the aperture can be set to multiple f-numbers. A thermal link between the aperture members and a cryogenically-cooled surface ensures that the aperture members are also cryogenically-cooled.

  • Rut-less roller gate system, fully supported and balanced off ground
    Patent number: 8479448
    Abstract: A rolling gate (15) fully supported off the ground on three rails (14), (16), (20), which are supported on three in line horizontally spaced vertical posts (17), (18), (19). The frame (15) outside the fence line has two roller appendages (12), (13) that span the fence line and ride on the rails (14), (16) inside the fence line. The bottom longitudinal pipe member of gate (15) is a bottom rail (20). A middle roller (11) mounted low on post (18) inside the fence line extends across the fence line to control rail (20) outside the fence line. The rails have a minute separation making the gate like a train on tracks. The rails (14), (16) have adjustable connectors (22), (23) and are adjusted level. The leveling keeps bottom rail (20) level during operation and allows all three rollers (12), (13), (11) to maintain contact the entire length of rails (14), (16), (20).

  • EMERGENCY DEVICES
    Publication number: 20100328106
    Abstract: A warning system is provided, which is particularly useful as a person overboard warning system. The system comprises a trigger part, worn by a crew member, which emits a signal on immersion in water. This is received by a receiver part on the vessel and automatically causes a transmitter part, also on the vessel, to send a further warning signal to one or more other locations remote from the vessel. These remote locations may be other vessels or land based sites, for instance operated by the coastguard or other rescue agencies. The automatic nature of the onward transmission of the signal received by the vessel makes the system particularly suited to single handed sailors.
