Abstract: A water purification method and system, employing at least a first chamber and a second chamber to freeze a portion of a volume of impure water in the first chamber while melting ice in the second chamber.  The unfrozen liquid, which has a high impurity concentration, is drained from the first chamber.  The melted ice, from which up to 95% of the original impurities have been rejected during the freezing operation, is drained from the second chamber.  Then, a new volume of impure water is supplied to the second chamber, and the process continues with the roles of the chambers reversed.  The system includes at least one heat transfer fluid coil portion wrapped around (or disposed within) each chamber.  The system requires no scraping or transporting of frozen ice, requires no chemical or cartridge replacement, and can be embodied in a small housing suitable for use as a home or restaurant appliance.  The chamber dimensions and the duration of each freezing operation are optimized to maximize the rejection of impurities, given the freezing chamber temperature attainable by the heat transfer fluid coil and the desired system throughput rate.

Abstract: A multiharmonic adaptive phase jitter compensator for a high speed modem is provided.  The compensator includes an IIR (Infinite Impulse Response) filter for each harmonic of phase jitter for which compensation is desired.  The coefficent update of each IIR filter as well as the input to the primary jitter frequency IIR receives identical information from a phase detector which compares an equalized phase corrected signal entering a decision means with the ideal point determined by the decision means.  However, the IIRs for the higher harmonics are trained with different information. Thus, the primary jitter frequency as adaptively determined by the first IIR is fed to harmonic computation circuitry.  The harmonic computation circuitry then provides an adapted second harmonic to the second harmonic IIR, and adapted third harmonic to the third harmonic IIR, etc.  The outputs of all the IIRs are summed, and the cosine and sine of the sum are provided to phase correct the equalized signal before it enters the decision circuitry.

Title: Method and apparatus for the sensing of refrigerant temperatures and control of refrigerant loading
Inventor: GREGORY CHARLES
IPC: F25B5/02
Filed: 1989-07-27
Granted: 1994-06-21
Abstract: Abstract of the Disclosure A new method and apparatus are provided for sensing refrigerant temperatures in refrigerator systems, and for the control of refrigerant loading in a plurality of refrigerator evaporator circuit coils connected in parallel.  Such evaporator coils are supplied with refrigerant through a thermostatically controlled flow control valve, which is controlled by a sensor  to restrict the flow of the liquid refrigerant and ensure a predetermined amount of superheat.  The usual minimum superheat is about 5.5°C (10°F) and it is often found that the evaporator coil clearly is underloaded, and in the case of a multi circuit coil evaporator, that many of the circuit coils are underloaded.  To avoid this the refrigerant is rendered thoroughly turbulent and mixed, and in the multi-coil evaporator the flows issuing from all of the circuit coils are similarly thoroughly turbulated and mixed, by a turbulating and/or mixing device that intercepts the entire refrigerant flow just before the sensing of the superheat, thus ensuring that the temperature is accurately measured.  In the multi-circuit coil system the device averages the temperatures of all the flows, any liquid from circuits with lower heat transfer being broken, mixed with and evaporated by superheated vapour from circuits with higher hear transfer.  Different turbulator/mixer devices are described and two or more such devices may be used in flow series.  The amount of superheat can now safely be reduced to about 2°C (4°F), the efficiency of the entire system is increased, and close matching between valve size and coil loading is no longer required.

Abstract: An ultrasonic imaging agent is produced by a continuous sonication processing of an aqueous solution of heat-denaturable biocompatible protein.  The solution is carefully preheated to a temperature of incipient protein denaturation without forming insolubilized pro-tein.  A gaseous fluid, preferably air, is added to the solution.  In the sonication, the air-containing solu-tion is foamed, increasing the formation and concentra-tion of microbubbles, and the solution is further heated to insolubilize a portion of the protein, thereby encap-sulating the microbubbles and forming particulate micro-spheres.
