Abstract: ABSTRACT OF THE DISCLOSURE At least one connector for use in a window spacer assembly for spacing a pair of panes of glass to form an insulated glass panel.  The assembly includes at least two elongated tubular spacers, each having a predetermined internal cross-sectional area and arranged to be secured together by the connector for dis-position between the panes.  The connector is formed from a plastic and serves to connect the spacers together at a pre-determined angle, while enabling them to deviate readily from that angle without loosening the connection between the spacers to thereby facilitate the construction of the panel.  The connector comprises a pair of legs connected at a junction at the predetermined angle and each of the legs includes a free end from which a single, curved resilient finger  project backward and into the spacer to effect frictional engagement with the interior of the spacer by the leg, irrespective of manufacturing tolerances in the cross-sectional area of the interior of the spacer.  The cross-sectional area of the junction is substantially smaller than the cross-sectional area of the interior of the spacer to enable the legs to flex from the predetermined angular orientation.

Abstract: FLUID FLOW REGULATION     Abstract of the Disclosure Flow regulating apparatus comprises a turbulent-flow valve with a fluid supply connected at the upstream side thereof.          A fixed pressure bias is applied to the fluid upstream of the valve whereby the mass flow rate of fluid through the valve is directly proportional to the pressure differential across the apparatus when these variations are within a selected pressure range.  Such flow regulation may be used in a system for intro ducing a metered amount of liquid fuel into an air stream to provide a combustible air-fuel mixture having a substantially constant air-to-fuel ratio.  With this system air is passed through a constricted zone to increase its velocity to sonic, and the area of the constricted zone is varied in correlation with operating demands imposed upon the engine for which the mixture is produced.  A liquid fuel supply is under the influence of atmospheric pressure, and fuel is metered from the supply into the air stream by controlling a fuel valve of the turbulent-flow type in direct proportion to the area of the constricted zone, the fuel valve being exposed to the pressure of the air stream.  The fixed pressure bias is applied to the liquid fuel supply so that the mass flow rate of fuel through the valve varies in direct proportion with variations in atmospheric pressure.     -1a-

Abstract: ABSTRACT:  A spiral spring interconnects a pivotably mounted drive lever that nay be pivoted either by hand or by a motor, and a pivotably mounted toggle lever that is operably connected to a switch.  The toggle lever is held in the switch-closed or the switch-opened positions by main latches which hold the toggle lever in position while the drive lever is pivoted to bias the spring.  Once the spring is biased, stop latches engage the drive lever holding it in a spring biased position.  The main latches may then be either manually operated or operated by solenoids connected to control circuitry to release the toggle lever so that the spring will react against the toggle lever to either open or close the switch depending on the position of the switch at the initiation of operation.  Once the switch has either opened or closed, the spring may be either re-charged automatically by the motor, or if manual opera-tion is desired, the motor can be disabled so that the spring can be biased by manual rotation of the drive lever.  A clutch mechanism is provided to disconnect the motor from the mechanism when a manual tool is inserted into the mechanism.  Also provided is a shutter bolt that locks out automatic operation of the main latches when the manual tool is inserted, electrically disconnects the motor, and prevents manual operation of the main latches when the tool is inserted into the mechanism.     Also, if it is desirable to test the solenoids without tripping the main latches, a mechanism is provided to manually disconnect solenoids from the main latches.  In addition, in case the switch blade is welded or stuck in the closed position, an automatic pry-out mechanism is provided to assure contact separation during switch opening.

Abstract: TREATING SOLID FUEL                         ABSTRACT A method of treating fine particles of solid carbonaceous fuel of the coal or coke type that comprises mixing the fuel particles with a liquid aqueous solution comprising essentially (a) sodium, potassium, or lithium hydroxide together with (b) calcium, magnesium, or barium hydroxide or carbonate, or a plurality thereof, with a ratio of (a) to the fuel of about 0.04 to 0.70 (typically 0.10 to 0.35) by weight, a ratio of (b) to the fuel of about 0.02 to 0.30 (typically 0.08 to 0.20) by weight, and a ratio of water to the fuel of about 1 to 10 (typically  2 to 5) by weight; heating the resulting mixture, at an elevated pressure, to a temperature of about 150 to 375° C (typically 175 to 300° C) in such a manner as to improve the usefulness of the fuel particles; and cooling to below about 100° C.  The cooled mixture either is dried or filtered to separate the fuel particles from the solution, the particles then being washed and dried.  The filtered solution is regenerated so that it can be again mixed with unreacted fuel particles.  The solution typically comprises essentially sodium hydroxide and calcium hydroxide or carbonate, and may comprise also magnesium hydroxide or carbonate.         A substantially continuous treatment comprises the steps of (a) continuously introducing the fuel particles at a preselected rate into the liquid aqueous solution to form a slurry, (b) moving the slurry through a region maintained at the elevated pressure and temperature, (c) moving the slurry outside the region of step (b) and separating the easily removable liquid phase from the solid fuel particles, (d) moving the fuel particles away from the separated liquid phase, and washing the particles.  Typically the separated liquid phase is regenerated by removing any impurities therefrom and is recycled as the liquid aqueous solution in the continuous process.
