Abstract: ABSTRACT     Alkali metal halates, such as sodium chlorate-containing liquors when produced in electrolytic cells may contain hexavalent chromium compounds which are objectionable impurities when permitted to remain in such products.  These impure cell liquors adjusted to a pH of 5.5 to 9.5 are treated with divalent iron salts, such as ferrous sulfate or products formed from the reaction of divalent iron salts and hydrazine to reduce the soluble chromium (VI) compounds present to a hydrous ferric-chromic oxide precipitate.  Separation of the pre-cipitate leaves a colorless chlorate-containing solution which is virtually free of chrome impurities.  The chrome values of the precipitate are recovered as soluble chromium (VI) compounds by reacting with bleach or other oxidizing agents leav-ing an unreacted, disposable sol ? of nearly chrome-free hydrous ferric oxide.  The recovered chromium compounds are available for recycling back to the electrolytic cell.

Abstract: Abstract Engine Compression Brake Employing Automatic Lash Adjustment A master/slave hydraulic-braking system for an internal combustion engine is disclosed for converting an engine from a power mode operation to a braking mode operation.  A slave piston (12) operates in one of three positions including a fully retracted position in which one end thereof is spaced from the associated exhaust valve structure (2,4,8) by at least a pre-determined lash sufficient to prevent contact between the actuating piston (12) and the valve structure (2,4,8) at all times during the power mode of engine operation, a brake actuated position in which the piston (12) is advanced sufficiently to open the exhaust valve (2,4) during the braking mode of engine operation and a brake ready position in which the piston (12) is advanced only far enough to take up the actual lash between the piston (12) and the associated exhaust valve structure (2,4,8) at all times during braking mode operation of the engine except when the actuating piston (12) is being advanced to open the exhaust valves (2,4). The disclosed system includes a lash take up means (58) including a biasing means (60) formed from a base support (62) attached to the actuating piston housing (16), an intermediate support (68) positioned between the base support (62) and one portion of the actuating piston (12), a first compression spring (70) extending between the intermediate support (68) and one portion of the actuating piston (12) for imparting a biasing force to the actuating piston (12) which tends to move the piston (12) from the brake ready position to the retracted position and a second compression spring (66) extending between the base support (62) and the intermediate support (68) for imparting to the piston (12) a biasing force which tends to move the piston from the brake actuated position to the brake ready position.  First and second stop means (74 and 76) are arranged to provide for a selective adjustment of the fully retracted and brake ready positions of the actuating piston (12).

Abstract: ABSTRACT      The use of a catalytic coating which acts to com-bine both the heat source and heat-transfer mechanism for a working fluid, such as that used in an external combustion engine.  Maximum heat exchange is accomplished by the direct bonding of the coating, per se, to the engine head with a compound of catalytic agents which confines heat of combustion directly thereto.  The preferred embodiment of the engine head surface may be finned or otherwise enlarged to provide for an increased surface area necessary for the heating of the engine head.  This means of surface combustion results in a highly fuel-efficient engine and/or heat source with very low exhaust pollutants.

Abstract: COOKING APPLIANCE INCORPORATING HEATER         ENERGY COUNTER MEANS                                  ABSTRACT           An arrangement for monitoring the approximate temperature of a resistive heating element selectively energized at a plurality of power levels in response to the selection by an operator of one of a plurality of power settings including OFF, which includes a heater energy counter to provide approximate heating element temperature information.  The heater energy counter is incremented at a rate which is approximately proportional to the rate of increase of the temperature of the heating element when energized at the selected power level.  In one form of the invention, the counter is decremented when a lower power setting or an OFF setting is selected, at a rate which is approximately proportional to the rate at which the temperature of the heating element decreases in cooling down to the temperature level associated with the new power setting.  By this arrangement, the count of the counter approximately tracks the heating element temperature, thereby providing approximate temperature information.  This temperature information can be used to energize an indicator light when the count of the counter exceeds a predetermined threshold count corresponding to a temperature above which the element is uncomfortably hot to the touch, which light remains ener-gized regardless of whether the element is ON or OFF until the count is decremented below the reference value, thereby providing a visual signal to the operator that the heating element is hot.
