Title: Method and apparatus for effecting a bioreaction
Inventor: WHELLOCK JOHN GRAHAM
IPC: C12M1/04
Filed: 1989-10-06
Abstract: A bioreaction is effected by gasifying, eg oxygenating, a liquid/solids mixture containing a micro-organism. The mixture is confined in an apparatus comprising a reaction vessel 10 and circulated around a loop, the loop including a column 4 in which gas transfer is effected e.g. by being introduced via line 8. The liquid is introduced into the top of the column at a velocity which is sufficient to generate and maintain, at least in an upper region of the column, a substantially continuous foam extending across of the column, and of relatively uniform bubble size, and also sufficient to prevent gas accumulating at the top of the column. The column may be located inside the vessel 10 or may be in the form of a continuous or segmented annulus around it. Processes mentioned are the liberation of metals from sulphide ores and the disulphurisation of coal. The exemplified process is the liberation of gold from pyrites using Thiobacillus ferro-oxidans. <IMAGE>

Title: Rolling-up small mesh pieces.
Inventor: MERCER FRANK BRIAN
IPC: B29B11/16
Filed: 1989-11-01
Abstract: It is known to use small, light weight mesh pieces having high flexural recovery, to strengthen a matrix. Such mesh pieces are very difficult to handle and package. In order to provide a suitable packaging system, mesh pieces 11 are deposited across the width of a moving run of flexible wrapping material 13 and are deposited in longitudinally overlapping relationship along the length of the wrapping material, by feeding the mesh pieces 11 on a belt 10 which moves more quickly than the wrapping material 13; the mesh pieces 11 are ejected from the end of the belt 10 onto the wrapping material 13. The direction of movement of the wrapping material 13 is inclined downwards so that the trailing ends of the mesh pieces 11 contact the wrapping material 13 before the leading ends contact the preceding mesh piece 11. The wrapping material 13, with the mesh pieces 11 on it, is then rolled up under tension into a spiral bale so that the overlapping edges curl down and prevent the mesh pieces 11 slipping out.

Title: Monitoring a machining operation
Inventor: OSMAN JOHN MICHAEL
IPC: B23Q17/20
Filed: 1990-02-14
Abstract: A distance sensor 8 is arranged to be moveable relative to a workpiece 2 during a machining operation so that the sensor-to-workpiece separation remains small enough for accurate measurement. The movement has a limit, defined by a stop 12, at a position where a finished workpiece would be within an accurate measuring range of the sensor. As machining progresses the sensor is moved towards the workpiece, stopping either when the separation of sensor and workpiece reaches a pre-set value or when the sensor reaches the limit of its movement. If the separation of sensor and workpiece reaches the pre-set value the sensor is moved away from the workpiece and then towards it again, repeating the cycle. If the sensor reaches the limit of its movement it remains in this position and measures its separation from the workpiece for the remainder of the machining operation. A datum block 3 may be used to define the desired finishing dimension. <IMAGE>
