Abstract: A B S T R A C T        A tangentially gas fired muffle comprises a hinged annular housing defining inner and outer annular chambers divided by a ring of heat resistant perforate or expanded material.  The outer annular chamber has inlets in the form of immersion tubes each locating an atmospheric burner, and outlet ports for discharging the products of the previous burner or burners.  The perforate or expended metal ring contains the combustion process in the outer annular chamber and also acts as a radiant for dissipating heat on a circumferential weld of two pipe section.  The gas burners are connected to a control console for supplying the burners continuously with gas at respective high and low flow rates.           Solenoid valves, connected to temperature controllers, provide the burners continuously with gas at respective high and low flow rates.  Energy regulators control the rate of heating.  A self-holding relay and a gas pressure responsive switch provide a safety feature for isolating the electrical and gas supplies in the event of a supply failure.

Abstract: Abstract of the Disclosure A redistribution process for the simultaneous production of dimethylaluminum chloride and numerous alkylaluminum chlorides is described herein.  The redistribution process is a chemical reaction which consists of first forming a mixture of methylaluminum dichloride and at least one alkylaluminum compound selected from the group consisting of an aluminum trialkyl, a dialkylaluminum chloride, and an alkylaluminum sesquichloride, where "alkyl" refers to a group containing 2 to 16 carbon atoms.  The relative amounts of the mixture components are fixed such that the mixture has a chlorine-to-aluminum atomic ratio of 1.0 to 2Ø  The mixture thus formed is next subjected to a fractional distillation, in which a first fraction is obtained, consisting of dimethylaluminum chloride, essentially free of trimethylaluminum, methylaluminum dichloride, and other impurities.  The distillation residue con-sists essentially of alkylaluminum chlorides, which are valuable commercial materials.  Dimethyl-aluminum chloride itself is useful as a methylating agent, a polymerization cocatalyst, a chemical intermediate, and a pyrophoric fuel.

Abstract: A B S T R A C T       Mounted adjacent and in alignment with workpiece sup-porting portion of a workpiece-shape-altering machine, such as the lower die of a stamping press, is a laser beam source, the outgoing beam from which passes through a beam splitter which divides the entering beam.  One of the two emergent beams from the beam-splitter is a workpiece position-inspecting beam which passes in a grazing direction across one portion of the top of a workpiece resting upon the lower die for subsequent stamping by the upper die of the press.  This beam continues onward to a mirror which reflects it in a grazing direction back across another portion of the top of the workpiece to a workpiece po-sition detector.  Theeother emergent beam from the beam split-ter is a workpiece presence-inspecting beam which is obstruct-ed by the workpiece, if present on the lower die, so that it does not reach the workpiece presence detector therebeyond. If, however, the workpiece has not been delivered to the lower die, or if delivered and worked upon, has adhered to and has been carried upward with the upper die, the workpiece presence detector immediately transmits the absence of the workpiece from the lower die to the electric control system of the press, which prevents the operation of the press until a workpiece, is properly supplied to and positioned upon the lower die.  On the other hand, even if the workpiece is in position on the lower die but is improperly positioned, such as being tilted, so that it obstructs the workpiece position-inspecting beam with the result that the beam does not reach the workpiece detector, the improper position of the workpiece is transmit-ted to the electric press control system, which thereupon prevents actuation of the press until the workpiece has been properly positioned upon the lower die by the operator.

Abstract: ABSTRACT OF THE DISCLOSURE            A water-cooled turbine rotor blade having an enlarged radially-extending chamber forming a coolant reservoir connected to cooling passages subadjacent the blade surface.  The channels interconnecting the reservoir with the passages are adjacent the blade tip so that the pressurized water (i.e. due to the centrifugal force caused by the rotation) in the reservoir flows into the channels at the tip and thence through the cooling passages radially inwardly.  Heat absorption from the blade causes vaporization of the water as it flows through the passages.  The cooling passage terminate radially inwardly (adjacent the hub or root portion) in a space in flow communication with the enlarged chamber and an exhaust port in the downstream face of the root so that vapor is exhausted at the downstream face and any liquid exiting the coolant passages is returned to the reservoir.

Abstract: ABSTRACT OF THE DISCLOSURE     A sluice box is disclosed for use in high volume placer mining operations and  a method of placer mining is disclosed,which are particularly useful for the recovery of gold from aggregate material.  In operation, aggregate material is loaded into an inlet trough of the sluice box where it is mixed with water to form a slurry.  A coarse recovery channel leads from the inlet trough and the sluice box is downwardly inclined, so that the slurry flows through the sluice box.          The inlet trough has a punch plate bottom for separating the slurry into a coarse slurry stream which passes on into the coarse recovery channel, and a fine slurry stream which drops through the punch plate.  A distribution section located below the punch plate has a generally conical and upwardly inclined floor, and angularly disposed vanes, so that the fine slurry stream is spread transversely and evened to produce a gener-ally uniform cross-sectional flow profile.  The fine slurry stream then passes into fine recovery channels  located beside the coarse recovery channel.  Both the fine and coarse recovery channels have bottom coco mat layers and transverse riffles located thereon for agitating the fine and coarse slurry streams allowing the gold particles to settle and be trapped in the coco matting.  The gold particles are trapped quickly without subsequent washing out, thus allowing high volumes of aggregate material to be processed through the sluice box producing higher recovery rates than in the past.
