Abstract: Provided herein is a granular filtration apparatus for the removal of particulate material from hot gas by contacting said hot gas with granular filtration material. The apparatus being of the type having a filtration chamber containing granular filtration material and having a tapered lower portion comprising at least one inlet tubing for feeding therein hot gases to be filtered and at least one outlet tubing for drawing filtered hot gas. The main feature of the present invention consists in a filtration unit mounted in the filtration chamber above each inlet tubing. The filtration unit comprising a first tubular member mounted above the inlet tubing so as to prevent granular material from entering or blocking said inlet tubing and a second tubular member having a bottom and a top end and being mounted essentially in a co-axial and spaced relationship above the first tubular member.

Abstract: A flexible device with fire-barrier properties has a plurality of fibrous sheets and dry particles comprising molecules that are chemically and physically stable at room temperature and that generate an endothermic reaction upon raising the temperature. The sheets are joined together and the dry particles are inserted between the fibers of each sheet by needle-punching.

Abstract: A device for use with an oil lamp to allow the diffusion of the scent of a perfume. The device has a circular vessel and a central tubular element extending longitudinally through the center of the vessel. A wick is inserted through the central tubular element. The vessel is closed at the bottom and open at the top, defining a perfume-holding area. In a first and second embodiment, the device also has an outwardly projecting lip along the circumference of the vessel at the top thereof. In a third embodiment, the vessel has a diameter that is greater than the diameter of the opening of the oil lamp, and is provided with a resilient member at the bottom of the central tubular element. In use, a user pours a given amount of perfume in the perfume-holding area. The device is then placed on the lip of the oil lamp and over the opening and the wick is lit. The heat generated by the flame of the wick heats the device, which in turns heats the perfume, thereby releasing a pleasing smell.

Abstract: Disclosed is a device for use in an oil lamp to allow the diffusion of the scent of a perfume added to the oil. The oil lamp has an inside and a lip lying in a generally horizontal plane. The device is a ring-shaped element having a plurality of inwardly downwardly protruding tabs that are spaced apart to define gaps therebetween permitting uninterrupted air flow between the inside of the bottle and the ambient air. The tabs have free ends defining an opening and are sized and shaped to receive and hold a wick supporting tube having a longitudinal axis perpendicular to the horizontal plane and an upper end from which a wick projects. The tube is inserted into the opening so that the upper end of the wick supporting tube is held in place at a given longitudinal distance from the lip.
