Patent CA-2132399-A1 (CA)
Title: Slurry separation
Inventor: ADAMS JOSEPH L
IPC: B30B9/12
Filed: 1994-09-19
Abstract: A screw press separator is provided herein for sepa-rating and deliquefying a slurry of solids and liquids e.g., a slurry of manure and water, or any other slurry of similar physical characteristics.  The separator includes a cylindrical housing having a slurry inflow port.   A cylindrical strainer basket extends rearwardly from the housing, the strainer basket having a cylindrical outlet end, and preferably being a longitudinally-slotted screen wall, for the passage of separated liquid therethrough.  A cylindrical discharge chamber extends rearwardly from the outlet end of the strainer basket to define a solids dis-charge opening.  An auger is disposed within the housing and the  strainer basket,  the  auger  including a  shaft extending through the housing, through the strainer basket and through the cylindrical discharge chamber.  The auger preferably has specially-defined auger flights affixed to an outer periphery of the shaft.   A spring-loaded door assembly which is connected to the shaft, is provided at the exit of the cylindrical discharge chamber.  A motor is provided for driving the auger for advancing the slurry rearwardly within the cylindrical housing.  The liquid is removed through the strainer basket and the residual solids are formed into a solid plug.  The solid plug is advanced through the cylindrical discharge chamber, but is prevented from rotating by keystocks situated within the cylindrical discharge chamber.  Because of the rotation of the auger shaft, the spring-loaded door assembly also rotates.  The door assembly is provided with longitudinally-extending tearing bolts to break up the plug.  Discrete solids are thereby discharged through the solids discharge opening between the end of the cylindrical discharge chamber and the forward end of the rotating door assembly.

Title: Polymer-supported catalyst for polymerization and copolymerization of olefins
Inventor: HSU CHENG C
IPC: C08F4/02
Filed: 1994-02-11
Abstract: A polymer supported catalyst comprises Ziegler-Natta catalysts immobilized on a magnesium-modified polymer support. The catalyst support is prepared by (1) dissolving a carboxyl group-containing polymer in a solvent and precipitating the polymer in a polar non-solvent, (2) wet-grinding the precipitated polymer, and (3) mixing the ground polymer with an organomagnesium compound or a complex of an organomagnesium compound and an organoaluminum compound to give a magnesium-modified polymer support. Optionally, the resulting magnesium-modified support is treated with a halogen-containing silicon compound. The catalysts may be loaded onto the support by reacting the magnesium-modified support with a transition metal compound to form a catalyst constituent, and then combining the catalyst constituent with an appropriate organo-metallic compound. The supported catalyst is highly active and suitable for the polymerization and copolymerization of olefins without substantial contamination of the resulting products with chlorine or metal ions, as is the case with conventional MgCl2-supported catalysts.

Title: Method and apparatus for signal decoder using instantaneous magnitude and phase detection
Inventor: HAINEY HERBERT W
IPC: H04L27/152
Filed: 1994-12-23
Abstract: Disclosed is a tone decoder (20) that identifies one or more tones encoded on an RF carrier signal for use in controlling various systems and devices located at a remote site. The tone decoder includes a bandpass filter (22), an A/D converter (24), and a tone detection component (26). An input signal having a nominal frequency fin is received by the tone decoder, filtered, and then converted to digital form for subsequent digital processing by the tone detection component. The tone detection component compares the input signal to a reference signal having a frequency fr. The tone detection component mixes the input signal with cophase versions of the reference signal to produce a cophase difference signal. The cophase difference signal is used to calculate the instantaneous magnitude and instantaneous phase of the mixed input and reference signal pairing. An indication of the frequency of the difference signal is determined by differentiating the instantaneous phase. The instantaneous magnitude and frequency calculations are then compared against threshold values to determine (a) the presence of a valid input signal and (b) whether the actual frequency fin of the input signal sufficiently corresponds to the frequency fr of the reference signal to indicate the presence of a tone.

IPC: C02F3/10
Filed: 1993-02-03
Abstract: A wastewater treatment plant for removal of organic matter, suspended solids and other pollutants comprising a pre-treatment chamber, a biofilm-aeration chamber and a settling chamber. Biofilm grows on biofilm support structure which is stationary and submerged in the mixed liquor of the biofilm aeration chamber. The combination of submerged or surface aeration and suspended solids particle size reduction occurs thereby creating a sufficient fluid flow within the biofilm aeration chamber. This combination of sufficient fluid flow, and reduced size suspended organic particles results in the efficient digestion of organic matter and pollutants by the biofilm growing on the biofilm support structure submerged in the biofilm aeration chamber. This results in a vastly more effective digestive process than conventional processes producing no sludge. Further, resulting treated effluent has a high dissolved oxygen content and low BOD and SS. The apparatus and process has the following advantages: low MLSS concentration, short biofilm incubation time, no clogging of the system, good response to shock loading, high DO in the effluent, consistent effluent quality, sludge is eliminated, wastewater treatment duration is shortened, the process is not temperature sensitive, plant design is greatly simplified, plants of the present invention are small by comparison to conventional plants, the present invention can be a significant step in the treatment of drinking water, energy consumption during treatment is low, the present invention is very cost effective, the process permits other purification processes to be used and the process is volumetrically and BOD insensitive.
