Abstract: SLIDE CONTROL ACTIVATED SWITCH INCORPORATING CAPACITIVE COMPONENTS          Abstract A control switch has an air gap safety lever, a novel slide switch arrangement, and an illuminated ON/OFF control switch. The air gap safety lever is mounted on the control switch so that no power may flow through the circuit until the unit has been installed and the front cover plate mounted.  The illuminated ON/OFF control switch utilizes a light pipe which conveys light from and LED to the ON/OFF button, the light pipe doubling as a mechanical link between the ON/OFF button and a momentary contact switch mounted inside the control switch.          Also, a novel frame is disclosed which secures all mechanical and electrical components of the switch together without the necessity of attaching a housing box, which simplifies test and repair before shipment of the unit from the factory.  The switch controllably inserts a variable capacitance in the circuit, thereby providing a detent indexing slide movement in switch operation.

Title: Hydrocyclone deinking and removal of sticky contaminants during paper recycling
Inventor: CHAMBLEE WAYNE
IPC: B03D1/14
Filed: 1991-06-12
Abstract: ABSTRACT      The removal of sticky contaminants and/or ink particles during the production of recycled paper is accomplished utilizing a hydrocyclone froth flotation process.  Paper having sticky contaminants from labels, tapes, hot melts, and other tacky substances, and/or print, is reduced to a finely comminuted liquid solids suspension of about 1-4% consistency (preferably over 2%).  The suspension is introduced into a first end of a vortex in a hydrocyclone, and the air is sparged radially inwardly into the suspension vortex by passing it through a porous inner wall of the hydrocyclone.  Lighter weight sticky contaminants move to the center of the hydrocyclone, facilitated by the radially inward movement of the sparging air, and hydrophobic sticky contaminants and/or ink particles attach to the air bubbles and form a foam.  The foam and lightweight sticky contaminants are removed from the first end of the vortex, while the pulp which has had sticky contaminants and/or ink removed therefrom is discharged from the second end of the vortex, opposite the first end.  A plurality of vertical axis hydrocyclones may be connected together in series, with a plurality of the series connected in parallel, to provide the most effective treatment.  Removal of sticky contaminants can be practiced prior to or simultaneously with deinking.

Filed: 1991-06-18
Abstract: The ignition switch for a vehicle such as a lawn and garden tractor is connected directly to a printed circuit board which also includes interlock systems components.  The circuit board with the switch and other components is wave soldered in an automated process to make good electrical connections for reduced voltage drops, thereby reducing the number of relays required.  Wiring harnesses are also soldered directly to the board during the soldering step.  In the preferred embodiment, the ignition switch is fixed to the board and supports the board from the console of the vehicle. However, if the switch or another component on the circuit board needs to be remotely located with respect to the remainder of the board, the switch or component is mounted on a break-away section of the board, and the wires connecting the board sections are soldered with the remainder of the components during the automated process.  After the board is manufactured as one assembly, the section is snapped apart from the remainder of the board, and the board and break-away section are mounted at the desired locations on the vehicle.

Patent CA-2050153-A1 (CA)
Inventor: BAIER BRUCE A
IPC: E06B3/66
Filed: 1991-08-28
Abstract: A true divided look is provided in an insulated two-pane window assembly through use of a resilient silicone foam internal muntin bar grid which is low in thermal conductivity to limit heat transfer between panes and is high in flexibility to allow for bending when forming curved shapes.  The grid is secured by adhesive on one side to one pane of glass, thereby allowing natural expansion and contraction of the glass panes.  The resilient muntin bar includes the resilient muntin bar being U-shaped with a base from which legs extend which are compressible and adapted to move laterally in response to pressure from the panes due to changing thermal conditions or bonding of external wooden muntin bars to the panes.  Movement of the panes toward each other would be limited by bottoming out against the base of the resilient muntin bar.

Title: Aqueous polyurethane-asphalt emulsion, substrates having coating thereof and method of using thereof
Inventor: HANNEMANN GERD K
IPC: C08L/
Filed: 1991-10-24
Abstract: ABSTRACT OF THE DISCLOSURE    A polyurethane/asphalt emulsion blend is prepared by mixing together an emulsion of a specific polyurethane with a specific amount of asphalt emulsion.  The polyurethane emulsion is prepared by mixing the polyurethane with water and an emulsifier additive, followed by addition of aqueous acid and subsequent stripping of sufficient water and solvent to give a polyurethane solid containing emulsion.  That emulsion is mixed with an asphalt emulsion so as to provide about 1-65% by weight asphalt solids in the final polyurethane-asphalt emulsion blend.

Patent CA-2056656-A1 (CA)
Inventor: PETERSON RUDOLPH A JR
IPC: F02N3/02
Filed: 1991-12-02
Abstract: An interlock circuit is provided wherein a foot switch connected through a diode to the alternator is depressed during rope-pull starting and provides power from the alternator to energize a relay and disable a magneto kill circuit to facilitate manual start.  As the engine turns over and current flows from the alternator, the relay is bootstrapped to the energized position so that the engine remains running even after the foot switch is released. Normal interlock features, such as those which rely on operator presence or the transmission being in neutral, remain operational without additional switches and without need for a battery being present in the circuit.
