Abstract: A method for removing methane and non-methane volatile organic compound concentrations from a gas stream. The method includes exposing the target gas to a halogen gas and a light from a suitable light source having a wavelength sufficient to activate halogen gas to halogen radicals, wherein the halogen radicals react with the VOC in the target gas to provide the target gas with a removed concentration of VOC as well as a device including a reaction chamber for reacting the halogen radicals with the VOC in the target gas.

Abstract: A roller shade assembly includes a roller tube including a first end opposite a second end, the roller tube defining an opening longitudinally extending between the first and second ends, and an idler assembly partially received by the opening at the first end, the idler assembly including an idler housing, a plunger received by the idler housing, and a biasing member configured to apply a biasing force onto the plunger, wherein the plunger is configured to slide relative to the idler housing, and the plunger is configured to selectively engage a bracket member.

Abstract: A wastegate valve for a bypass path for a turbocharger in an internal combustion engine, the wastegate valve comprises a valve seat defining a plane which is non-orthogonal to the principal flow axis for gases flowing along the bypass path and a valve member pivotable from an open position to a closed position, wherein in the closed position the valve member is seated on the valve seat, and in a fully open position the valve member is positioned to direct gases exiting the bypass path onto a leading face of a catalytic converter monolith for heating the monolith.

Abstract: An impeller for use in a pump assembly for a fluid circuit of an engine of a vehicle comprises a plurality of projections provided at radially spaced locations relative to a rotational axis of the impeller, the impeller being rotatable relative to a housing of the pump assembly. The projections extend axially from a surface of the impeller and circumferentially about the rotational axis of the impeller. At least one of the projections is configured to be at least partially received in a recess provided in the housing such that a flow path is provided by the projection and the respective recess, wherein the flow path provides a tortuous flow route for fluid between an inlet and outlet of the pump assembly so as to restrict flow of fluid along said flow path and thereby minimise flow of fluid from the outlet back towards the inlet in a direction opposite to the intended direction of flow.
