Abstract: GAS-FILLED HIGH CURRENT BUSHING WITH      FORCED COOLING ARRANGEMENT   ABSTRACT OF THE DISCLOSURE        The gas-filled bushing of a two-pressure circuit breaker has a hollow central conductive stud.  Heated gas is injected into the annular chamber between the stud and the porcelain jacket of the insulator at the insulator flange, and the chamber is isolated from the interior of the circuit break-er housing.  This gas flows up to the top of the bushing and into the open center of the conductive stud, and down into the low-pressure housing of the circuit breaker.  A gas orifice restricts the flow of gas into the bushing to a small value and a compressor maintains a given pressure differential between the low-pressure gas and its high-pressure source.  The heated gas maintains the gas in the bushing and in the housing at a temperature greater than -40°F.

Abstract: A B S T R A C T      A new article of manufacture formed by a new method and apparatus for generating and substantially uniformly electrostatically dispersing a very finely divided spheroidally shaped lubricating particles onto the moving surface of metal or other electrically con-ducting substrate.  A lubricant material in its liquid state is drawn by airflow through a small venturi orifice where it is sheared into droplet  of various sizes. Larger droplets are filtered out of the continuing post-venturi airflow by gravity, baffles, airflow forces and/or inertia effects, leaving only a mist cloud of extremely small spheroid particles which are then migrated within a charged plasma so as to transfer electrical charge thereto in sufficient quantities to achieve a desired uniform high charge/mass ratio and thus insure a uniform eventual electrostatic dispersion of substantially all the spheroids over the substrate surface.  The mist cloud is controll-ably generated for each of a plurality of longitudinal sections of the substrate and permitted to drift or migrate relatively slowly between transversely positioned electrodes and the conducting substrate spaced therefrom in respectively corresponding longitudinally partitioned sections of a non-conducting enclosure.  A corona discharge is maintained by a voltage differential between the electro-des and the substrate to form an electrically charged plasma within the non-conducting enclosure, which in turn, multiply bombards and charges the individual particles of the slowly migrating mist cloud.  Thusly charged to uniform charged states, the particles are then uniformly dispersed substantially only by electrostatic forces onto the surface of the longitudinally moving substrate.  The percentage coverage of the tiny lubricating spheres on the conducting substrate surface is dependent only upon the quantity of such particles migrating into the part-itioned enclosure and the relative velocity (and hence dwell time within the enclosure) of the conducting sub-strate.  The coverage is substantially uniform because of substantially uniform charge/mass ratios provided; because of the controlled uniform supply of the particles across a transverse dimension of the substrate and because the longitudinally partitioned non-conducting enclosure prevents non-random movement of the tiny spheres as they enter the partitioned enclosure and prevents any tend-ency to deposit the charged particles on the enclosure surfaces rather than on the substrate, per se.

Abstract: ABSTRACT     A machine for cutting grooves in workpieces, parti-cularly in sheet form, having at least one fixed cutter, support means for supporting the workpiece against the cutter and means for moving the workpiece relative to the cutter and support means.  The cutter has a cutting edge defining the shape of groove to be cut and is arranged to slice through the workpiece to produce a groove leaving a constant thickness of material between the bottom of the groove and the other side of the work-piece.  The forces tending to lift the workpiece from its support due to the action on the cutter of material removed thereby are overcome and a resultant force operating to press the workpiece on to its support is produced by arranging, either singly or in combination, that (a)  the cutter has a cutting edge substantially contained in a plane which extends forwardly in the direction of relative movement of the cutter and upwardly of the surface of the workpiece, (b)  the cutter has a bevel face which faces the workpiece and extend rearwardly from the cutting edge at a negative angle of clearance to the workpiece.

Abstract: Abstract of the Disclosure An air-conditioning apparatus of the reversible heat pump type includes a booster heat exchanger for the refrigerant gas. The booster heat exchanger receives refrigerant from or in parallel with the evaporator or outdoor coil during the heating mode of operation and adds additional superheat to the gas by ex-posing it  to convective or radiant ambient heat, or both. A temperature sensitive valve controls flow through the booster heat exchanger to the compressor of the apparatus, to prevent compres-sor damage due to excessive suction temperature. The booster is automatically shunted out of the refrigerant flow line when the apparatus is operating in the cooling mode, to control the load on the compressor and ensure proper operation during cooling. Substantial increases in operating efficiency are obtained.
