Patent CA-2768506-A1 (CA)
Title: Apparatus having a spring element for treating obstructions within body lumens
Inventor: KROLIK JEFFREY A
IPC: A61M31/00
Filed: 2010-07-23
Abstract: An apparatus for treating obstructive material and/or other obstructions in a body lumen of a patient is provided that is operable in different modes to perform various functions for treating a body lumen. The apparatus includes a shaft including proximal and distal ends, a lumen extending therebetween, and a balloon on the distal end. The apparatus includes a valve on the distal end that selectively opens or closes an outlet communicating with the lumen. With the valve open, fluid introduced into the lumen exits the outlet into a body lumen. With the valve closed, fluid introduced into the lumen expands the balloon. The valve may be biased to be closed, e.g., by a spring element disposed within the balloon. Optionally, the apparatus also includes an actuator for expanding a helical member within the balloon interior, e.g., either before or after expanding the balloon, such that the helical member and balloon may adopt an expanded helical shape for removing material within a body lumen.

IPC: B01D45/10
Filed: 2010-11-09
Abstract: The present invention relates to an air cleaner for removing air pollutants from an air stream, for instance such as the cleaning exhaust/intake gas of an amusement machine, said air cleaner comprising a filter device including at least one filter layer (4a, 4b) held by a filter holder (5) in said airflow substantially perpendicular to a main flow direction thereof and including a plurality of preferably stick-shaped filter elements (6) neighbouring each other. In accordance with the present invention, the filter device has no closed surrounding along the circumference of the filter layers, but provides for an open side along at least a portion of the periphery of the filter layer. At least one circumferential side section (7, 8) of the filter layer parallel to or tangential to the longitudinal axis of an outermost filter element is formed as an open side free of flow control elements surrounding the filter layer. Contrary to the prior art where the filter layer is usually enclosed in a tubular flow channel, the present invention avoids such flow-control- elements for guiding the air stream through the filter layer and/or preventing the airflow from diverging away from the filter layer, wherein in particular the filter layer, at its open side, is dispensed with flow-control-elements such as flow guiding surfaces, flow channel walls, fences or housing walls surrounding the filter layer.

Title: Method and apparatus for automated launch, retrieval, and servicing of a hovering aircraft
Inventor: MCGEER BRIAN T
IPC: B64F1/00
Filed: 2012-06-21
Abstract: An aircraft capable of thrust-borne flight can be automatically retrieved, serviced, and launched using equipment suitable for a small vessel. For retrieval, the aircraft hovers over a base apparatus having one or more rails which bound a space into which the aircraft can safely descend. When the aircraft's measured position and velocity are appropriate, the aircraft descends promptly such that a spanwise component on the aircraft engages the rails. The teeth restrain the aircraft in position and orientation, while the rails bring the aircraft to rest. Articulation of the rails is used to park the aircraft in a servicing station. Connections for refueling, recharging, and/or functional checks are made in preparation for launch. Launch is effected by removing connections and restraints and articulating the rails to put the aircraft in an appropriate position and orientation. The aircraft uses its own thrust to climb out of the apparatus into free flight.

Inventor: BYRNE JOSEPH H
IPC: F04B39/00
Filed: 2011-06-17
Abstract: A sacrificial body mitigates cavitation damage to components within a pump. The sacrificial body is mounted in the pump so that flowing fluid passes over the sacrificial body, which causes the sacrificial body to shed electrons into the flowing fluid in the vicinity of the cavitation. The excess electrons tend to suppress hydrogen ions from releasing, which can mitigate cavitation. The sacrificial body is formed of a material having less resistance to corrosion due to the flowing fluid than the components of the pump. Needles are attached to the sacrificial body for immersion in the flowing fluid to facilitate the release of the electrons for the sacrificial body.

Abstract: The present invention relates to a gasket (1) comprising a first discrete component and a second discrete component, wherein the first and second components (20) extend along the length of the gasket (1). The second component (20) is arranged relative to the first component (10) so as to separate the first component (10) at least from one of the two sealing surfaces (2, 4). The first component (10) is relatively hard in at least the thickness direction of the gasket (1) and preferably incompressible and the second component (20) is relatively soft in at least the thickness direction of the gasket (1) and compressible. When the gasket is compressed between two flanges (101, 102), there is a limited region of high compression, because the first component (10) increases the pressure by which the second component (20) is compressed between the surfaces of the flanges. This yields a high leak tightness of the sealing at a relatively low force.
