Title: Method of forming fine polymer particles and polymer-encapsulated particulates
Inventor: HOU WEI-HSIN
IPC: G03G9/093
Filed: 1992-01-21
Abstract: Fine polymer particles and polymer-encapsulated particles are formed by dissolving a polymer in a selective solvent, either lowering the temperature of the solution and/or adding thereto, a non-solvent for the polymer precipitating the polymer from the solution. Particulate material may be included when the solution is formed so that when the polymer precipitates out of the solution, the polymer encapsulates the particulate material. Two homopolymers are placed in solution with the selective solvent so that one polymer precipitates first out of the solution and is suspended therein, the other polymer is precipitated later out of the remaining solution, encapsulating the one polymer particles, forming core/shell polymer particles. Pigments, liposomes and other particulate material can be polymer encapsulated, the polymer and polymer-encapsulated particles being uniform in size and morphology.

Abstract: A soil penetrating tool assembly for mounting to a tool bar of a soil penetrating implement including a shank member which has an elongate body, a soil penetrating tool which is located on the first end of the body and a facing plate located on a second end of the body.   The facing plate engages one side of the tool bar, and has a first end and a second end which has an opening.  A clamp-ing plate engages the other side of the tool bar, and has a first end and a forked second end which has two prongs each having openings  including two sections,  generally oblong  in cross-section,  offset  from one another with different centerlines.   The facing plate first end and clamping plate first end include facing flanges each having a through hole and a bolt secures the flanges together with a clearance therebetween.  The opening sections in each of the clamping plate prongs and the facing plate opening define a generally cylindrical passage therethrough with a selected diameter when the shank member is mounted to the tool bar,  and a shear pin extends through that defined passage.

Title: Telephone system communication mechanism employing central office sleeve lead
Inventor: SULLINS LESLIE A
IPC: H04M3/30
Filed: 1992-04-03
Abstract: A data communication and sleeve lead control apparatus provides auxiliary signalling between a no-test trunk control unit (12), and another unit such as a pair gain unit (14) which is coupled with the link between the control unit and the no-test trunk, while maintaining stability of the sleeve lead (5) monitored by the no-test trunk ( 16). The apparatus is installed within the pair gain unit, and effectively isolates the sleeve lead (5) to the no-test trunk (16) from sleeve lead (5) to the no-test trunk control unit (12), so that, the data communications between the. control unit and the pair gain unit are transparent to the no-test trunk (16). During a prescribed sleeve lead current flow state, e.g. high resistance or low current flow, controlled interruption of sleeve lead current between the control unit and the pair gain unit effectively modulates the state of the sleeve lead therebetween; but does not change the intended current flow state applied by way of the sleeve lead output port to: the no-test trunk.

Inventor: STIE KENNETH E
IPC: F25B43/04
Filed: 1993-12-22
Abstract: The presence of an undesirable quantity of noncondensible gases in a refrigeration unit is inferred as a function of both the vapor pressure and temperature at a selected point in the refrigeration unit where the noncondensible gases tend to gather.  Purging of these noncondensible gases, which contaminate the refrigerant, is responsive to a comparison in a programmable controller of the actual vapor pressure measured at the selected point, and the known pressure of uncontaminated refrigerant at the temperature existing at the selected point.   On detecting a difference between these pressures that is greater than a desired value, the controller calculates a control output signal needed to purge a volume of contaminated vapor from the unit that is effective for reducing the difference between the measured pressure of contaminated refrigerant and the known pressure of uncontaminated refrigerant to a desired value.
