Abstract: An illustrative aspect of the invention provides a filtration apparatus comprising a filtration element having a plurality of filtration media sheets and at least one reinforcement element positioned intermediate adjacent filtration media sheets. The reinforcement element has a body that is formed from a planar member having a plurality of apertures to allow passage of fluid therethrough. At least a portion of a surface of the reinforcement element is in contact with one of the filtration media sheets. At least a portion of another surface of the reinforcement element is in contact with the other filtration media sheet. Each of these surface portions defines a plane that is parallel to the filtration media sheet with which the surface portion is in contact.

Abstract: A method and apparatus for scanning a workpiece (100) comprises providing an insert (120) insertable within a countersunk bore (106), the insert (120) being acoustically mounted to the workpiece (100) in order to scan regions below the countersunk area.

Abstract: A door stay device for automatically locking a door in an open position includes a first component adapted to be attached to a stationary support, the first component including a plate having a curved cam edge with a radius matched to a swinging movement of the door between closed and open positions. The plate has a slot open at the cam edge at a location corresponding to the open position of the door. A second component is adapted to be secured at a lower or upper edge of a door, the second component having a locking member arranged to move into the slot when the locking member is aligned with the slot and the door is in the open position.

Abstract: Apparatus for classifying a ray is disclosed, wherein the ray is received at a code division multiple access receiver. The apparatus comprises: means for receiving a neighbouring cell list comprising at least information concerning scrambling codes used by at least one neighbouring cell; means for selecting a scrambling code used by a given neighbouring cell; means for mixing a received signal with the selected scrambling code to provide a mixed signal; and means for examining the mixed signal to determine if the ray originates from the given neighbouring cell.
