Patent CA-2135392-A1 (CA)
Title: Helicopter
Inventor: SAKURA KIYOSHI
IPC: B64C27/00
Filed: 1994-03-16
Abstract: A cabin 1 of a helicopter is separated structurally from an airframe 2, and the cabin is supported on the airframe 2 by using both springs 6 and actuators 7. The high frequency vibration, which is the mast uncomfortable high frequency component of the number of revolutions of rotor, is absorbed by soft springs, and the resonance of the spring and the rotor rotation is actively inhibited by actuators, so that the vibrations of wide frequency is removed from the cabin, thereby achieving comfortableness to ride in the helicopter.

Patent CA-2149772-A1 (CA)
Title: Fine particle handling
Inventor: WILLIAMSON RICHARD
IPC: B65D77/06
Filed: 1994-10-20
Abstract: A method and assembly for removing fine particles in an essentially dust-free manner which features a semi-bulk container bag (54) that is removed from a reusable protective container (120), hoisted off the ground and punctured with a discharge probe (22). The puncturing of the plastic bag is achieved by inserting a spear shaped probe with tapered nozzle head (24). The probe is sealed with respect to the bag. The nozzle head includes a plurality of elongated discharge openings (76), as well as a nozzle tip (70) with a plurality of injection ports (72). Fine particles having a size of less than 400 µ, are fluidized and then discharged out through the discharge openings by a suction device. Fluidization is achieved by injecting air or inert gas through the tip of the nozzle head. The fluidized fine particles removed from the bag are passed through the discharge openings, out through the probe, through a flexible conduit (34) and to a storage or further processing device (52). The bag is preferably formed of an anti-static or conductive material to prevent the attachment of fine particles to the interior surface of the bag.  Sealing is preferably achieved by sliding a locking sleeve (102) into contact with a cup-shaped member (88) which pinches the plastic between the cup-shaped member and the rear end (96) of the nozzle head. The probe is grounded and preferably conductive so as to provide a dissipation circuit with respect to the conductive bag.
