Title: Airflow control mechanism
Inventor: PEARS BARRY
IPC: F24F13/12
Filed: 2007-02-19
Granted: 2011-06-21
Abstract: The present invention provides an airflow control mechanism comprising a conduit for air having an inlet located at a first end thereof and an outlet located at a second end thereof; a first opening formed in a side of said conduit and able to provide a secondary inlet thereto; a movable collar at least partially surrounding said conduit at a location alignable with said first opening, such that said collar is able to at least partially occlude said first opening; further comprising a second opening beside the first opening as part of the secondary inlet, wherein the collar is also alignable with the second opening, such that the collar is able to at least partially occlude the second opening at the same time as the first opening. Thus with this airflow control mechanism, a user may select whether to occlude both the first and the second openings, in which case air will pass directly from the inlet to the outlet without any air also entering through the secondary inlet, or to occlude neither the first and second openings, in which case air entering the secondary inlet will contribute to the total amount of air exiting the outlet, or to occlude just one of the first and second openings, in which case, a fixed amount of air which is less than the secondary inlet being fully open, but more than the secondary inlet being fully closed, will enter through the secondary inlet and contribute to the total amount of air exiting the outlet. Thus the user will be provided with a highly predictable and repeatable setting for the airflow control mechanism between the fully open and fully closed positions of the secondary inlet.

Abstract: A mask for use during painting shields those components of the contents of a wall box which will be exposed through a decorative plate used to cover the wall box after the wall is painted. The mask is a substantially flat thin sheet with an adhesive substance applied to its face along its outer perimeter for adhering the sheet to the wall. The substance may be continuous or may be spotted about the perimeter. A pad of identical masks can be temporarily held in stacked laminar relationship by the adhesive substance. The mask may also have a raised portion of perimeter, depth and location suitable for shielding any of the contents of the box which protrude from the box beyond the plane of wall surface. The raised portions may be tapered to facilitate nesting of identical masks in a pad temporarily held in stacked laminar relationship by the adhesive substance.

Title: A method for the manufacture of a coating having a columnar structure
Inventor: DAMANI RAJIV J
IPC: C23C4/134
Filed: 2007-09-11
Granted: 2014-10-28
Abstract: In the method for the manufacture of a coating (10) having a columnar structure, preferably a dense structure, a coating material in the form of primary corpuscles (1) is injected with a carrier gas into a thermal process beam. The coating material is transformed in the process beam into a vapour phase and is deposited as condensate in the form of a columnar coating on a substrate (100). The primary corpuscles are liquid droplets or they are formed in each case by an agglomerate of particles (2) which are held together by cohesive forces of a connecting medium or by adhesive forces. The liquid droplets include a chemical precursor of the coating material in the form of a salt solution and are transformed by thermal action in the process beam into secondary corpuscles containing particles (2). The primary or secondary corpuscles are disintegrated in the process beam by mechanical and thermal interaction. In this connection, the particles are dispersed so that coating material is vaporised fully or partly on the individual particles by thermal action.
