Abstract: A method of treating lake water to remove suspended solids and to precipitate and inactivate phosphorus comprises ad-ding aluminum hydroxide sulfate to the water in a concentration such that the pH of the water is maintained at a level of greater than 6.0 and precipitation of suspended solids and precipitation and inactivation of phosphorus occurs. This invention is advan-tageous in that it provides a method of removing suspended solids as well as precipitating and inactivating phosphorus in water while simultaneously preventing the solubilizing of toxic amounts of aluminum into the water with subsequent detrimental effects to aquatic life.
Patent CA-2087394-C (CA)
Title: Pressure signal processing apparatus and method for an automatic blood pressure gauge
Inventor: NEWELL SCOTT W
IPC: A61B5/022
Filed: 1993-01-15
Granted: 1996-12-03
Abstract: An  automatic blood  pressure  gauge  uses  two pulse width modulated  solenoid  valve  to  achieve  a  substantially  linear deflation curve.  The solenoid valves are controlled by a valve switching signal that has a fixed fundamental frequency.  The gauge samples and digitizes the cuff pressure signal. To eliminate artifacts related to the valve switching signal, a microprocessor in the gauge filters the sampled data pressure signal using a third-order Chebychev 2 filter having a zero at the frequency of the valve switching signal.   A single timing source used for controlling the microprocessor is also used for developing both the valve switching signal and the sampled data pressure signal, in order to achieve high attenuation of the valve switching signal components in the pressure signal via the Chebychev filter.   In addition,  the analog to digital converter which develops the digital samples is a sigma-delta type converter which has a Nyquist frequency greater than the frequency of the valve switching signal and which includes a low pass filter that further attenuates the switching signal artifacts relative to the patient's blood pressure pulse signal.  Additionally, one of the solenoid valves is used when relatively low flow rates are desired from a relatively highly pressurized cuff while the other valve is used when relatively high flow rates are desired from a cuff having a relatively low fluid pressure.

Abstract: Fluid proportioning system for proportioning a fluid intermittently at various places. This fluid come from a storage point and is added by an intermittently operating pump to a proportioner, which feeds a fixed volume of fluid to an outlet more or less independently of the pressure. For returning the reciprocating piston present in the proportioner, use is made of a further fluid which is connected to the proportioner by means of a further inlet line. A forced return movement of the piston is thereby achieved. Proportioning of fluid is realised by the proportioning fluid itself whilst return movement in the proportioner of the piston is realized by the control fluid.

Abstract: The invention relates to a process for separating gaseous components from pourable media. The main feature of the invention is that regions of underpressure are formed by relative movement between the media and a body arranged therein owing to the latter's shape and that the gas collecting in said underpressure regions is evacuated via the interior of the body. A device for separating gaseous components from pourable media is primarily distinguished in that it is designed as a device for generating a relative movement between the media and a body (1) arranged therein, said body being, in particular, arranged to rotate and having a contour which produces underpressure regions (8) on the surface of the body during this relative movement and the body (1) has at least one inlet (5) around the underpressure regions (8) which communicates with a gas outlet inside the body to remove the separated gas. The invention also relates to an installation using the device of the invention.

Abstract: Apparatus for imparting a spiral spin on a fluid in zone 2 surrounding a columnar substance in zone 1 which may be a metal electrode or a fluid, such as gas for welding. The spirally spinning fluid may be an inert gas for sheathing zone 1 down to the welding site on a workpiece. For a four-stroke-cycle internal combustion engine, exhaust gas return (EGR) in zone 1 is sheathed from a fuel-air mixture in zone 3 by the spirally spinning fluid (fresh air) in zone 2. In a two-stroke-cycle engine, the spirally spinning fluid in zone 2 may be injected gas while the EGR is inject-ed in zone 1. Fresh air, precharged in the cylinder at the end of the power stroke, constitutes zone 3.      In either the four-stroke or two-stroke-cycle case, the spirally spinning fluid in zone 2 and the columnar EGR are positioned on the axis of the cylinder, and the spirally spinning fluid provides a blended mixture of air and fuel for combustion with a cylindrical flame front that progresses rapidly down around the column of EGR to the piston and from there radially out to the cylinder wall as the piston moves down in the power stroke.
