Abstract: An anchor assembly (A) for hollow walls comprises an anchor body (400) and a toggle member (231) that is displaceable between a first position wherein the toggle member (231) is substantially aligned with the anchor body (400) such that the anchor assembly (A) can be inserted in the wall (W) via a cutting distal end (325) of the toggle member (231), and a second position wherein the toggle member (231) extends behind the wall (W) at an angle relative to the anchor body (400) which extends through the wall (W). The toggle member (231) is held captive in the first position but is released and then rotated to the second position by a fastener (218) introduced in the anchor body (400). The fastener (218) threadably engages the toggle member (231) thereby drawing the toggle member (231) against a hidden side of the wall (W).

Abstract: The present disclosure relates to a method for extracting lithium from a lithium-containing material. For example, the method can comprise leaching a roasted lithium-containing material under conditions suitable to obtain an aqueous composition comprising a lithium compound such as lithium sulfate and/or lithium bisulfate. The aqueous composition comprising lithium sulfate and/or lithium bisulfate can optionally be used, for example, in a method for preparing lithium hydroxide comprising an electromembrane process. The roasted lithium-containing material can be prepared, for example by a method which uses an aqueous composition comprising optionally lithium sulfate and/or lithium bisulfate which can be obtained from a method for preparing lithium hydroxide comprising an electromembrane process such as a two-compartment monopolar or bipolar electrolysis process.

Abstract: An anti-rat flap member for sewer/draining pipe check is removably attached to the valve body. The valve body defines an interior volume therein which is preferably substantially open and unobstructed (except for the flap member). The flap member acts both as a seal to prevent the back-flow of sewage/drainage water and is normally in a closed position to prevent the passage of rats. The flap member comprises a row of sharp projections attached by known means (such as integrally molded, glued, rivetted or screwed) to the outermost side of the flap member facing the downstream section of the valve. The projections must be at an angle to the surface of the sheet, preferably at an angle which will prevent the rodent from gnawing and biting or even lifting the flap member with their mouth.

Abstract: A method and a system of imaging a scene are disclosed. The method can include acquiring, at a frame chip acquisition rate, a plurality of frame chip images of the scene while repeatedly scanning the scene across a range of focus positions. The method can also include generating, from the plurality of frame chip images, a sequence of fused frame images. A fused frame image is generated by a focus-stacking operation on a stack of N consecutive ones of the plurality of frame chip images, at least one of the N frame chip images used in generating one of the fused frame images also being used in generating at least another one of the fused frame images. The fused frame images can be displayed at a refresh rate greater than 1/N times the frame chip acquisition rate. A method of motion artifact reduction in focus-stacking imaging is also disclosed.

Abstract: Systems and methods related to the near elimination of second-hand smoke or vapour from the process of smoking or vaporizing tobacco or Cannabis are provided. A vaporizing article is provided whereby a user may exhale into the article to capture a high percentage of the smoke and contaminants before they are released back into the surroundings. The article also provides for filtering gaseous by-products when the article is in idle mode. A prepackaged container for use with a vaporizing article is also provided. The container may be configured so as to optimize the heat distribution and consumption of product within the container.
