Abstract: The present application relates generally to pipes, and specifically to screens for the bowls of smoking pipes. The screen for a smoking pipe bowl of the present application includes a wire coil forming at least one ring and defining an upper side and a lower side. The wire coil is configured to be received in a smoking pipe bowl to support a quantity of fuel on the upper side and the wire coil configured to permit fluid flow therethrough between rings of the wire coil. A related method of forming a screen for a smoking pipe bowl is also described.

Abstract: A filtering apparatus includes first, second and third chambers, the first chamber in use receiving a mixture of liquid and matter to be filtered, the second chamber in use receiving the mixture be filtered from the first chamber via a weir, and the third chamber in use receiving liquid from each of the first and second chambers, the first chamber having an outlet 18 at a low position which is connected via a conduit to the third chamber and which opens into the third chamber at a first height, to discharge liquid into the third chamber when the liquid level in the first chamber exceeds the first height, and the second chamber having an outlet at a low position which is connected via a conduit to the third chamber and which opens into the third chamber at a second height, to discharge liquid into the third chamber when the liquid level in the second chamber exceeds the second height.

Abstract: An apparatus for separating from a liquid mixture, first and second liquid components such as oil and water, wherein the first liquid has a greater density than the second liquid, includes a vessel (10) having an inlet (13) through which the mixture is introduced into the vessel (10), and an outlet (14) through which separated first liquid is in use discharged, and there being a separating member (12) within the vessel (10), the mixture being constrained to contact the separating member (12), the separating member (12) including a material which adsorbs the second liquid component characterised in that the separating member (12) is adapted to move in the vessel (10) downwardly in response to an increase in the weight thereof as second liquid component is adsorbed.
