Title: Method and apparatus for treating material in a rotary hearth furnace
IPC: F27B9/18
Filed: 1979-01-12
Abstract: Method and apparatus for feeding an oxidant such as air and/or a fuel rich gas within the confines of a substantially airtight enclosure employed in the heat treatment of volatile containing materials which are deposited on the floor of a rotary hearth mounted within the enclosure. The oxidant is admitted into the furnace enclosure through concentrically arranged rows of inlet openings 28 formed in the roof of the enclosure. The oxidant mixes in the upper portion of the enclosure with the volatiles evolved from the materials and combusts therewith and following combustion of the said oxidant and released volatiles the waste gases of combustion are caused to travel radially outwardly to a peripherally mounted exhaust manifold 30 whereas the material undergoing heat treatment on the hearth are gradually advanced from the point of entry thereof to a centrally located discharge outlet 24. Means are provided in the exhaust manifold to cause said oxidant and waste gases of combustion to travel in a line of direction outwardly of the enclosure and into the said exhaust manifold. Thus, the direction of flow of the oxidant and waste gases of combustion within the enclosure is counter-current to the direction of travel of the materials undergoing treatment on the hearth. The amount of oxidant fed to the control area of the furnace is less than the amount fed at the periphery so as to produce a less oxidising atmosphere in the central region. <IMAGE>

Title: Displacement electrophoresis
IPC: G01N27/447
Filed: 1979-07-24
Abstract: Displacement electrophoresis is carried out on a gel (11) having the form of a tube along which substances are separated in the axial direction. The method makes use of an agarose or polyacrylamide gel (11) formed on and supported by an inner tube (12) which also acts as a conduit for coolant. Very thin gels are used to provide a short path for heat removal e.g. up to 3 mm. The gel is supported on one side only and the other side is in contact with electrolytes used in the process i.e. leading, displacing, and terminating electrolytes. To avoid drying out of the thin gel it is maintained in contact with an inert water-immiscible liquid where it is not in contact with electrolyte. The method is of especial importance for the separation of ampholyte molecules such as proteins or peptides. To provide an indication of the extent of separation fluorescent ampholytes are used as marker substances in very small quantities.

Title: Scanning Apparatus for Flaw Detection
IPC: G01N21/89
Filed: 1979-07-30
Abstract: Test apparatus and method for testing for faults in, for example, transparent sheet material in which two parallel beams of light separated by a distance "nw" where n is odd are scanned across the material and then passed through a grating having, light transmitting and absorbing areas of equal width "w" in the direction of scan, so that as the two beams are scanned across the object and the grating the light output through the grating is generally constant. If, however, there are faults which displace one beam with respect to the other, then the spacing between the beams will change so the light output will vary from the norm. Furthermore, if there is a fault which would cause attenuation of the two beams, then the light output will again vary from the norm. In alternative embodiments, light may be reflected from the material, the grating may have reflecting and transmitting areas and a grating may be provided for each beam. <IMAGE>

Title: Degassing device
IPC: B01D19/00
Filed: 1980-09-29
Abstract: In a degassing device the liquid, e.g. blood, is caused to move in a downward helix in a chamber 1, gas being separated from the liquid by centripetal force and tending to accumulate in the centre of the helix and rise. To assist the accumulation of gas and reduce turbulence a solid surface, e.g. a tube 12, may be provided axially of the helical liquid path. The pressure in the liquid at the bottom of the helical path may be greater than that at the top, increasing the buoyancy of gas bubbles. This pressure rise can be caused by a reversal of the direction of angular flow of the liquid near the outlet 10. The device may take the form of a cylinder with tangential inlet 6 and outlet 10 tubes. In another embodiment, the liquid flows through a duct following a radially decreasing downward helix, the duct has radially inward orifices to allow gas to escape into a central space. <IMAGE>
