Abstract: A method of preparing a substrate for substrate bonding is provided. The method comprises: forming a recess in a substrate surface of the substrate, and forming a bondable dielectric layer on the substrate surface of the substrate. The bondable dielectric layer has a bonding surface on an opposite side of the bondable dielectric layer to the substrate surface, wherein the recess and the bondable dielectric layer define a dielectric cavity having a dielectric cavity volume. A plug is formed configured to make electrical contact to the substrate in the dielectric cavity volume. The plug has a plug volume which is less than the dielectric cavity volume, wherein the plug extends from the dielectric cavity beyond the bonding surface in a direction generally normal to the bonding surface. The plug is coined by compressing the substrate between opposing planar surfaces such that a contact surface of the plug is made co-planar with the bonding surface.

Abstract: A catch basin trap for attachment to an opening in a side wall of a catch basin. The catch basin trap has a body with a front side for facing outside the catch basin, and a back for side facing inside the catch basin. The body defines a chamber, an inlet opening in the back side, and an outlet opening in the front side. A collapsible outlet pipe connector is attached to the outlet opening, configured to be manipulated from a collapsed configuration to an extended configuration defining a discharge end for coupling to an outlet pipe positioned outside the catch basin. The collapsed configuration stows the collapsible outlet pipe connector within the body, and the extended configuration permits watertight coupling of the discharge end to the outlet pipe. A method of installing a catch basin trap, and a method of making a concrete catch basin are also disclosed.

Abstract: A double wall structured combustor having an outer wall having an inner surface and an outer surface and an inner wall comprising a plurality of tiles. Each tile has at least one interlocking member at a first wall and at least one interengaging member at a second wall. The interlocking member extending through an aperture in the outer wall, and the interengaging member at the second wall engaging with a cutaway section in the first wall of an adjacent tile. On assembly of the combustion chamber, the interlocking members and interengaging members of the tiles ensure lower profile fixings and an overall reduction in number of conventional fasteners used.

Abstract: A method of producing cooling apertures in a combustion chamber head includes mechanically drilling a plurality of cooling apertures through the combustion chamber head from the downstream side of the combustion chamber head. A tool is inserted through at least one aperture for a fuel injector from the downstream side of the combustion chamber head and the tool is rotated about its axis while within the aperture for a fuel injector. Fluid is supplied from the drilling machine through the tool and jets of fluid are directed from nozzles in the tool with at least a radial component towards the cooling apertures on the upstream side of the combustion chamber head to remove burrs and/or caps adjacent the cooling apertures. The present disclosure enables cooling apertures to be drilled through a combustion chamber head using conventional mechanical drilling in a viable and cost effective manner.

Abstract: A self-service system is provided that can automatically identify one or more existing groups to which a user can self-select to access a resource. The self-service system can identify any suitable existing group without requiring an administrator to predefine groups according to roles. In some implementations, the system intelligently identifies one or more suitable groups for a user from a list of available groups by analyzing a set of rules or criteria. For instance, the system can perform a weighted analysis of various rules and/or criteria to automatically and dynamically identify groups that have a closest fit to the access rights needed or requested by the user. Further, the system can evaluate certain best or preferred grouping practices to identify suitable groups. As a result, in certain embodiments, the self-service system alleviates planning burdens on administrators and provides greater flexibility in providing users with access to resources.
