Abstract: ABSTRACT        A process and apparatus for dispersing solids in  a  liquid  phase  are  disclosed.     A  mill  base comprising solids and a liquid phase is fed into a hollow body having a substantially cylindrical inner surface and containing a grinding medium and at least one sieve. The mill base is fed radially inwardly into the hollow body toward the sieve,  while the grinding medium  is rotated relative to the hollow body and the sieve at such a speed that the grinding medium forms an annular charge in contact on an outer side with the cylindrical inner surface of the hollow body  and  defining on  an  inner side  a cylindrical space  essentially  free  of  the  grinding medium  in which  is  situated  the  sieve.    The mill  base  is conveyed  radially  inward  through  the  cylindrical charge of grinding medium toward the sieve so that a fluidized bed is formed with respect to the grinding medium.    The  mill  base  is  subsequently conveyed radially inwardly through the cylindrical space which is essentially free of grinding medium to the sieve. The mill base is sifted radially inward through the sieve and  is separated  from any  residual grinding medium.  Preferably, the mill base is sifted by means of  a cylindrical  sieve  disposed centrally  in  the hollow body or by means of a plurality of cylindrical sieves  disposed  in  a  circular  array  about  a longitudinally axis of the hollow body.   The sieves may be stationary or rotatable with respect to the hollow body.

Abstract: POWER CONTROL CIRCUIT FOR MAGNETRON    ABSTRACT OF THE DISCLOSURE           A duty cycle power control circuit for a magnetron including a power transformer having a primary winding, a secondary anode winding for supplying anode voltage to the magnetron and a secondary filament winding for energizing the filament of the magnetron.  In the illustrative embodiment the power transformer primary winding comprises a main winding and a serially connected standby winding.  Duty cycle controlled switching devices are effective in a standby state to connect the main winding in series with the standby winding across an external power supply and are effective in the power on state to disconnect the standby winding and connect the main winding directly across the external power supply.  The ratio of the standby winding turns to main winding turns is selected such that when the standby winding is serially connected to the main winding the anode voltage supplied at the secondary of the power transformer is below the minimum anode voltage level for microwave energy generation and when the standby winding is disconnected from the main winding the secondary anode voltage is greater than this minimum anode voltage level; in either instance the filament voltage is sufficient to maintain the filament temperature high enough to avoid moding in the magnetron.

Abstract: Abstract An oil-spill-combatting water craft for recovering oil which is present on the surface of water. The water craft has at the water level at least one water inlet and, secured just behind this inlet, a collecting boom (2) which extends forwards and outwards, directing water to inside the craft, where there is a separating device (5) for the recovery of the oil from the water. In the water craft of this type the difficulty so far has been that, when the craft travels at a somewhat higher speed, water pressure in front of the boom tends to rise so high that some of the oil-contaminated water (3) "escapes" under the boom (2). According co the invention, this is prevented by arranging, for at least part of the water from which the oil has been separated and which discharges from the craft, an outlet just behind the collecting boom (2). For the rest of the discharging water there is preferably arranged an outlet which is located further towards the  bow than is the inlet.
