Abstract: A device and a method for producing a fine liquid mist and injecting the said mist into a gas stream to capture and remove very fine particulate pollutants. The pressurized gas stream is passed into a droplet generator (20) into which the liquid is sprayed and atomised into a mist which captures particulates and then into a droplet separator (30) to produce a separated liquid/particulate mixture and a gas stream with a reduced concentration of particulates. The main application is the removal of fine particulates from vehicle exhaust streams. Optionally a degassing stage (90) is provided for the removal of residual gases and vapours. The preferred liquid to form the mist is water.

Abstract: A combined exerciser and physical fitness performance monitoring apparatus and related methods. The apparatus includes at least one fluid working device, such as a pneumatic ram, which serves to provide an adjustable load. The fluid working device is movable using an adjustable mount to vary the compression ratio and loading rate. The fluid working device is connected to a user interface, such as foot pedals or hand holds, using a connection linkage. The apparatus also preferably includes a load modifier which adjustably engages the connection linkage and allows the rate of mechanical loading to be varied. This construction allows a large range of loads and force rates to be achieved.

Abstract: A method for the design and performance of a process such as scrubbing, stripping, heat transfer from one stream to another, and removal of particulate constituents from a gas stream.

Abstract: A method for treating a gas stream to remove heat, gaseous, liquid or particulate matter, or add heat, vapor, or moisture, which includes the steps of:providing a tower having a bed with fluidizable hollow ellipsoidal packing with a long semi-axis and a short semi-axis;introducing a liquid stream into the tower at a liquid flow rate L, and countercurrently introducing the gas stream into the tower at a gas flow rate G sufficient to maintain the bed in a fluidized state and a gas velocity v; andadjusting the volume ratio of the liquid flow to gas flow to cause the ellipsoidal packing to circulate predominantly in the vertical direction relative to the long semi-axis and to maintain a pressure gradient .DELTA.P/H.sub.o across the depth of the fluidized bed of at least about 1500 Pa/m, and, simultaneously, to satisfy the equation:L/G=K.sub.1 (.DELTA.P/H.sub.o v)+K.sub.2wherein L/G is the volume ratio of liquid to gas; .DELTA.P is the pressure drop across the bed; H.sub.

Abstract: A warning apparatus includes a body member for disposal around at least a portion of the hand and the wrist; a warning member for emitting a warning signal attached to the body member; and a switch for actuating the warning member attached to the body member so that the switch is substantially adjacent to at least one finger of the hand and being electrically connected to the warning member so that actuation of the switch causes the warning member to emit a warning signal. The apparatus preferably has at least two rigid protective support members arranged to follow front and back contours of the wrist.
