Patent CA-2010670-A1 (CA)
Title: Salient pole rotor for a dynamoelectric machine
Inventor: DYMOND JAMES H
IPC: H02K9/06
Filed: 1990-02-22
Abstract: A dynamoelectric machine has a stator with a stator core and a plurality of spaced apart radially extending ventilation ducts.   A rotor mounted for rotation within the stator has a shaft with a plurality of salient poles.  Each salient pole has a winding on it and each pole with its winding constitutes a pole member. Adjacent pole members define between them an interpolar space.  Cooling air enters each interpolar space from each end when the machine is operating, moves generally axially as portions of the air change direction to move radially outwards through the air gap separating the rotor and stator and then through the ventilation ducts. The air flow, in a radial outward direction, tends to be less at the ends of the rotor and through the ventilation ducts adjacent the ends of the stator.  The invention places a baffle at each end of each interpolar space. The baffle is in a generally radial plane and has an outward edge adjacent the outer limit of the interpolar space as defined by the tips of the poles, and an inward edge spaced from the bottom of the interpolar space.  The baffle improves the air flow radially outwards adjacent the ends of the rotor and the stator.

Abstract: Method for improving particular interconnect pads for microcircuitry so that they provide more compliant interconnections between opposed pairs of contacts of the microchips in a hybrid detector array assembly.  The individual tubes of prior art interconnect pads are filled with indium and are then etched away to leave indium columns of increased height, relative to the indium bumps that have heretofore been used in the contact connections of hybrid detector array assemblies.  Other materials may be substituted for the indium and a number of variants of the process are also disclosed.

Abstract: A steam iron pump assembly including a two-position selector having one position corresponding to a sudden discharge of steam and having its other position corresponding to spraying cold water.  According to the invention the pump assembly comprises a pump body surmounted by a deformable bellows, and having two side outlets together with a rotary selector passing through the deformable bellows.  A bottom portion of the rotary selector is surrounded by a sealing sleeve which is radially deformable level with one or other of the two side outlets from the pump body.          The outline of the bottom portion is suitable, depending on the angular position of the rotary selector for applying the sleeve against one of the outlet orifices while simultaneously allowing water to pass through the other outlet orifice.

Abstract: A mobile, self propelled pothole patching vehicle is provided having a truck chassis  and cab.  The pothole patching vehicle includes an asphalt conveyor system for delivering asphalt to the road surface from a storage hopper mounted on the chassis.  The conveyor system is uncoupled from the hopper and is movable with respect to the rest of the vehicle both longitudinally along the axis of  the  vehicle  and  transversely  in  a  side-to-side swivelling motion. The conveyor is provided with a conveyor housing having a slotted top panel  through which the asphalt passes into the conveyor interior. A conveyor mount slidably receives the conveyor and is pivotally coupled to the discharge port and the chassis for lateral swivelling motion of the extendible conveyor. During longitudinal and lateral  movement  of  the  conveyor,  the  discharge  port opening into the housing interior remains within the ambit of the slotted portion of the top panel for continuous delivery of asphalt. The pothole patching vehicle of the present  invention  also  includes  a  heated  tamper  for providing a smooth finish to the freshly packed asphalt and which minimizes asphalt sticking to the tamper. The heated tamper is also utilized to heat air from a compressed air source for pre-drying potholes before being filled.

Abstract: Automatic Knife Sharpening Method For Forage Harvesters Abstract of the Disclosure In a forage harvester having a motor driven sharpening stone driven back and forth along a path parallel to the axis of a rotating cutterhead to sharpen the knives of the cutterhead, and a door which normally prevents access to the knives, a control circuit is provided for controlling the opening of the door, the movement of the sharpening stone to sharpen the knives, and the closing of the door after the knives have been sharpened.  The circuit is controlled by switches located at an operator's control panel and accessible to the operator while he is in the driver's seat of the harvester so that the operator does not have to leave his driving position to accomplish the knife sharpening operation.  The circuit includes visual indicators located on the control panel for indicating the status of the circuit during the entire operation.  The circuit includes a sensor circuit for sensing the rate of rotation of the cutterhead, the sensor circuit preventing knife sharpening from taking place unless the cutterhead is rotating at a rate greater than the rate required for proper sharpening of the knives.

Abstract: Abstract of the Disclosure Disclosed is a method and apparatus for drawing an elongated glass article such as a fiber optic device.  The article is drawn upwardly from a source through the surface of a quantity of molten metal having a vertical temperature gradient.  The source can be an elongated solid glass preform that is vertically positioned within the molten metal such that the temperature of that portion of the molten metal adjacent the upper end region is sufficiently high to heat that region to drawing temperature. The upper end region is pulled to form a tapered root, continued pulling resulting in the formation of an elongated article from the small diameter root end.  The relative position of the root is maintained with respect to the surface of the molten metal during the drawing operation.  Alternatively, the glass can be drawn from an orifice located within the molten metal.     The apparatus includes container means for supporting the molten metal, and external or internal means for heating and/or cooling portions of the molten metal.  The container can also be provided with baffle means for dividing the container into a plurality of chambers.
