Abstract: A Traffic Handheld Control Warning Sign including a first and second display sign which are fastened together and have the capability to display different traffic control warnings and commands simultaneously. The invention is battery powered and can be controlled by a separate or built in remote control. The invention can be hand held or can be used hands free by placing it in a tripod or pole and operating it with a remote control from a distance of up to 40 meters.

Abstract: A rotary tobacco treatment cylinder includes an elongate hollow cylinder arranged to rotate about its longitudinal axis and disposed substantially horizontally or inclined by a small angle to the horizontal, a series of elongate paddles extending longitudinally within the cylinder and extending generally towards the longitudinal axis from the inside surface of the cylinder, the paddles serving to convey material to be treated from a lower position within the conveyor and around one side to an upper discharge position. Each of the paddies has a proximal portion extending at a first angle being a right angle to the tangent at the root of the proximal portion or an angle less than a right angle at the loaded side of the paddle, and a distal portion which is inclined to the proximal portion at a second angle, which is less than the first angle, to form a tip. A major part of the tip considered longitudinally is of a length (viewed axially of the cylinder) less than half the length of the proximal portion.

Abstract: A method of preparing a cigarette filling comprising tobacco and a partly fibrous herbal or spice additive, comprising processing the additive to form a sheet material thereof, cutting that sheet material into generally leaf sized portions, blending the cut sheet material with tobacco in the desired ratio of additive to tobacco, and subsequently cutting, drying or otherwise treating the blended material to form a cigarette filling. The invention is particularly but not exclusively concerned with the use of cloves as the additive.

Abstract: A fluid filter has a bundle of hollow fibres (40) within a casing. At one end of the casing (40) there is a header (41) which has a feed passageway (55) therethrough and in communication with the interior of the casing (40) and the exterior of the fibres. The header (41) also has a filtrate passageway (64) therethrough and in communication with the open ends of the fibres.

Abstract: A fluid filter has a bundle of porous hollow fibres (40) within a casing. At one end of the casing (40) there is a header (41) which has a feed passageway (55) therethrough and in communication with the interior of the casing (40) and the exterior of the fibres. The header (41) also has a filtrate passageway (64) therethrough and in communication with the open ends of the fibres. At the other end of the casing there is a second header (42) which has a treated feed passageway (72) therethrough and in communication with the interior of the casing (40) and the exterior of the fibres. The header (42) also has a filtrate passageway (74) therethrough and in communication with the open ends of the fibres. The feed, treated feed and filtrate passageways (55, 72, 64 & 74) area formed in the off set portions (56, 73, 65 & 75) of the headers (41, 42) that have planar parallel end faces whereby a plurality of filter units may be joined together without a manifold to form a bank of filters.
