Filed: 2000-08-29
Abstract: Arsenic filtering media consisting essentially of calcined diatomite particles and between 5% and 30% by weight of ferric ions bonded to the calcined diatomite particles. One method for producing the filtering media consists of: generating a mixture of calcined diatomite particles and ferric chloride; allowing the mixture to sit for an extended period, thereby allowing ferric chloride to thoroughly impregnate the diatomite particles; and slowly adding sodium hydroxide to the mixture until the pH of the mixture reaches a value of at least 9.0, for ensuring unhasty and full oxidation of ferric chloride into ferric hydroxide. The filtering media thus obtained have strong and durable bonds between ferric ions and the diatomite particles. The filtering media are renewable several times with minimum reduction to their arsenic adsorption capacity. A method for renewing the filtering media comprises in-situ desorption of arsenic using sodium hydroxide and rinsing with water.

Title: Apparatus and method for selecting a mechanical seal
Inventor: GREENLIE DAVID G
IPC: G06Q30/06
Filed: 1999-03-02
Abstract: An automated seal selection, seal design, manufacturing, and post sales allows a distributor or untrained user to select a replacement seal for a pump. The automated system designs and engineers the seal, whether standard or special, and creates all drawings, documentation, quotations and other output forms.  The automated system initiates selection from inventory or purchasing of materials to be used in the manufacturing operations, creates all manufacturing CNC programs for the components to be manufactured and downloads to CNC from manufacturing equipment. The system allows selection of a seal based upon a seal part number, or selection of a seal based upon the pump into which the seal will be installed and the operating conditions of the pump. The pump maybe defined by searching through a database of existing pumps, or may be defined as a new pump if it is not in the pump database. Results of a previous compatibility analysis, perhaps performed by the seal manufacturer, may be accessed for existing pumps, or an on-line compatibility analysis may be performed for new pumps, to determine whether an existing seal fits the pump with no modification. If no existing seal fits, the system provides two options. In a first option, a special seal is specified which will fit the pump with no modifications to the pump. An integrated design system determines dimensions for the special seal and its various components in real time providing immediate quotations including drawings. With a second option, modifications to the pump are defined so that a standard seal will fit. After a seal is specified, the system recommends materials of construction and allows the customer to select materials and other selectable options.

Title: Process for the manufacture of a sulfenimide
Inventor: BALDERSON PHILLIP B
IPC: C07C313/36
Filed: 1999-05-06
Abstract: A process for the manufacture of a sulfenimide by reacting sulfenamide in slurry with an organic water immiscible solvent with an acid to yield a solvent slurry comprising sulfenimide product. The product is recovered from the solvent slurry by a method comprising the addition of water to the solvent slurry and the isolating of the product by a single filtration step. While water is added to the solvent slurry an azeotrope of solvent and water may be distilled under vacuum until substantially all solvent is separated from product and product becomes part of an aqueous slurry. Alternatively, water may be added to the solvent slurry while the resulting mixture is being agitated, followed by filtering the mixture in the single filtration step for recovery of product from the mixture.
Patent CA-2334063-A1 (CA)
Inventor: PARENT LUC
IPC: G01F23/26
Filed: 2001-02-02
Abstract: The system and the method are used for detecting a level of liquid metal at a given location, such as a launder set between an holding furnace and a casting pit.  The system comprises an emitter coil and a receiver coil in a side-by-side configuration and in close proximity of the location. In use, an AC signal is applied to the emitter coil for producing an alternating magnetic flux. At least a part of the magnetic flux passes through the location where the level of liquid metal needs to be measured and goes back into the receiver coil. The signal in the receiver coil is monitored and the data are conveyed to a control module which determines the level of liquid metal from the variation of the signal in the receiver coil. The coils of the system are advantageously provided with respective core elements having a high magnetic permeability and which are configured and disposed to channel the magnetic flux. As a result, the system is not significantly affected by the presence of steel on the frame side of the launder and is capable of determining the level of liquid metal with a high signal to noise ratio. It can also be used at other locations besides a launder.

Title: Circuit for timed position control of device driven by a dc motor
Inventor: GRANDY MARK E
IPC: B60R1/07
Filed: 1999-05-28
Abstract: The present invention relates to an electronic circuit that interrupts the application of electrical power to a motor after a predetermined period of time. The electronic circuit is disposed between a motor which drives a device from an initial position to a final position and a switch movable from a position to a second position. A battery which supplies the electrical power for the motor is engaged with the switch. The control circuit includes at least two energy storage devices. Depending on the position of the switch, one of the energy storage device will be fully charged by the battery source.  Altering the position of the switch will cause the fully charged energy storage device to begin its discharge and the alternate energy storage device will be "instantly" charged. During the time that both energy storage devices have a significant charge on them, a control signal is generated. The control signal will be present until the discharging energy storage device falls below a threshold value. In response to the control signal, the electrical power source is applied to the motor and the motor will turn in the direction according to the polarity of the applied power source. In a second embodiment of the invention, electrical power to the motor may be interrupted prior to a full discharge of the energy storage device if the current drawn by the motor exceeds a predetermined threshold value for a minimal time period.
