Patent CA-1220167-A (CA)

Abstract: ABSTRACT A method is disclosed for classifying sand wherein a mixture of sand and water is introduced into a classification tank partially filled with water.  Depending on the weight of the sand grains, the grains of sand will precipitate at the bottom of the tank at graduated distances from an inlet pipe, the heavier particles nearest the inlet and the lighter particles farther away.  To prevent large quantities of fines, i.e., sand grains between about 0.002 mm and 0.006 mm in size, from being lost by being washed out of the tank together with the overflow water, the water from tile tank is recirculated by means of a pump so that the water becomes progressively more saturated with fines, which means that larger amounts of fines will precipitate in the tank.  Because the water is recirculated, water consumption can be reduced by 2/3, and at the same time the problem of the overflow water from the tank is also reduced.

Abstract: TWO-STROKE INTERNAL COMBUSTION ENGINE AND METHOD OF OPERATION THEREOF           ABSTRACT OF THE DISCLOSURE     An internal combustion engine comprises a combustion chamber and a piston movable relative to the combustion chamber between top dead center and bottom dead center positions.  A fuel transfer passage introduces fuel-air mixture into the combustion chamber in response to piston movement.  An auxiliary chamber is also provided which is communicable with the combustion chamber in response to piston movement shortly after the ignition of a fuel-air mixture, such that high pressure ignition gases enter the auxiliary chamber.  The high pressure ignition gases thereafter flow back into the combustion chamber in response to piston movement before communication is established between the combustion chamber and the fuel transfer passage.  The incoming flow of high pressure ignition gases serves to influence the normal scavenging streams.  The auxiliary chamber can also junction as an auxiliary transfer passage in response to piston movement to supplement the fuel transfer passage in supplying a new fuel-air mixture charge to the combustion chamber.  In one embodiment, an air transfer passage is provided for introducing fresh air into low pressure regions in the cylinder to lend overall stability to the scavenging process.

Abstract: PYROLYTIC OVEN CLEANING SYSTEM                 ABSTRACT OF THE DISCLOSURE         A cooking oven of the heat-cleaning type in which substantially all of the energy for heating the oven to heat-cleaning temperature is initially supplied by the upper or broil heating element.  The broil unit is initially energized to raise the oven cavity temperature to the heat cleaning range during which time volatile portions of food by-products are evaporated, whereupon the broil unit is de-energized and the lower or bake heating element energized to maintain the temperature of the oven cavity in the heat cleaning range.  The location of the lower bake unit relative to the lower wall of the oven cavity is dimensioned to insure that the temperature of the more difficult to clean front portion of the lower wall of the oven adjacent the door opening is maintained at heat-cleaning temperature for a time sufficient to effect removal of food by-products.

Abstract: Abstract of the Disclosure In known pyrometers for gas-turbine engines, the temperature of different regions along the length of a turbine blade can be determined by focussing radiation from the blade with a lens onto a row of ends of several fibre-optic bundles.  Arranging the ends of the bundles in a row does not, however, use the radiation focused by the lens very efficiently.  In the present invention, the bundles are arranged in a jig with one bundle being positioned centrally and two other bundles of C-shape located on opposite sides and extending around the central bundle.  In this way, the end of the three bundles forms a circular area with an efficient utilization of the radiation focus by the lens.

Abstract: DEMAND RESPONSIVE FLOW CONTROL VALVE            Abstract of the Disclosure A demand responsive flow control valve mechanism has a valve member which receives fluid flow from a power steering pump and delivers a predetermined amount of fluid to an operating system such as the power steering gear.  The excess fluid delivered by the pump is directed by the valve member to a bypass port from which the excess fluid is returned to the pump or a reservoir.  The fluid flow to the operating system is controlled by differential areas disposed on a spool valve and a flow regulating orifice sensitive to system flow for determining the pressure differential to be applied to the differential areas.  The operating system has a variable orifice which serves as a demand regulator for establishing the pressure level requirements for the pump.  The valve spool responds to the pressure differential and system pressure level to bypass flailed as required.  A pair of check valves are disposed in the spool valve and are operable to provide two stages of pressure relief for the operating system.
