IPC: B01J13/18
Filed: 1991-09-03
Abstract: A process for making melamine-formaldehyde microcapsules in an aqueous solution containing a high concentration of a water miscible or water soluble organic solvent is provided. The aqueous solution is prepared and a water insoluble melamine-formaldehyde pre-condensate is dissolved therein by adjusting the temperature and organic solvent concentration of the aqueous solution such that the melamine-formaldehyde pre-condensate is barely soluble therein. A substance to be encapsulated, preferably an oily solution containing a dyestuff precursor, is dispersed into the aqueous solution to form an emulsion, the melamine-formaldehyde pre-condensate being insoluble in the substance to be encapsulated. The melamine-formaldehyde pre-condensate is separated from the aqueous solution onto droplets of the substance to be encapsulated and the self-condensation reaction of the phase-separated melamine-formaldehyde pre-condensate initiated to form capsule walls around the droplets, thereby producing melamine-formaldehyde microcapsules in the aqueous solution containing a high concentration of a water miscible or water soluble organic solvent.

Abstract: A drill bit for use in drilling a well bore comprises a main drill body (l0) adapted to be rotated about a substantially vertically disposed axis of rotation (20) and having therein a duct extending longitudinally along such axis, for supplying a drill fluid under pressure to the well bore. At least one generally circular, rotatable cutting discs (34, 36, 38) are mounted on the outside of the main drill body (10) at equally spaced locations, with the cutting discs each having cutting elements (35, 37, 39) disposed in a ring-shaped array.

Patent CA-2055562-A1 (CA)
Title: Filtering method and apparatus
Inventor: KALMAN PETER G
IPC: B29C48/691
Filed: 1991-11-14
Abstract: ABSTRACT Filtering apparatus includes two or more passages (2) acting in parallel, each having an extended filter (12) which passes through inlet and outlet ports (48, 49), flowable preferably sealed by solidified plugs of the flowable substance such as a polymer being filtered. The flow of such substance to one passage can be terminated so as to permit filter advance under conditions of zero pressure drop, whilst flow through the other passage continues. Filter advance can be assisted by extrusion of a sealing plug in the outlet port under the pressure of such substance from the other passage which is still filtering. In additional or alternative mode, flow into a passage is terminated and a secondary outlet (20, 21) in that passage is opened. This creates a counterflow under the pressure of substance from the other passage, which cleans the filter. The secondary outlet can be sealed by a plug which is extruded during counterflow. An alternative valve for the secondary outlet, which can also be used in a diverter valve for controlling the input of substance to the two passages, has a side passage (26) in which is formed a plug of solidified substance, and means (27) for pushing the plug into the flow substance.
