Abstract: Abstract of the Disclosure Disclosed herein is a drill bit for earth boring, including a lubrication system that eliminates necessity for a complex system to accomplish pressure compensation.          Since the temperature of the earth generally increases with depth from the surface, a drill bit experiences increasing temperature with increasing depth.  The coefficient of ther-mal expansion of lubricant inside a bit is greater than that of the metal defining the walls of the lubricant cavities.          Internal bearing lubrication pressure control is achieved utilizing thermal expansion of the lubricant, seal displace-ment, and a pressure relief valve.

Abstract: QUICK CHANGE IN-MOTION TOOL CHUCK                          (Holt) Abstract A tool chuck includes a spindle having a barrel with an axial bore therein, and a collar slidably disposed about the barrel.  A diametrical slot within the barrel receives a pair of opposed, pivoting toggles which engage and retain the end of a tool inserted in the barrel bore.          The toggles are pivoted by a pair of linking members secured to a cylindrical member disposed in axially trans-latable fashion in the upper end of the bore.  The cylin-drical member is translated by the collar by means of an annular slot therein which receives opposed shoulders entending from the cylindrical member through another diametrical slot.  Axial translation of the collar re-leases or secures a tool in the bore while the chuck is rotating at operating speed.

Abstract: ABSTRACT OF THE DISCLOSURE            Apparatus for transporting solid particles, such as frag-ments of coal or ore, from an underground excavation to a level above the ground has a liquid-containing underground vessel which receives solid particles from a conveyor or from lorries and whose lower portion is connected with the receiving ends of two parallel U-shaped pipes having discharge ends connected to the lower end of a riser.  One receiving end is connected with the outlet of a high-pressure pump for clear liquid (i.e., a liquid which is free of solid particles) when the other receiving end receives a mixture of solid particles and liquid from the vessel, and vice versa.  At the same time, the discharge end of the pipe which receives clear liquid communicates with the lower end of the riser to admit into the riser the (previously received) mixture of solid particles and liquid while the other discharge end communicates with the intake of a suction pump which delivers clear liquid to the vessel.  The valves which control the admission of mixture or pressurized liquid into the receiving ends and the valves which control the admission of mixture into the riser and the flow of clear liquid from the discharge ends of the pipes are rinsed with water or are automatically held out of contact with solid particles to reduce wear upon their moving parts.  The pumps convey clear liquid so that the wear upon their parts is also negligible.  A booster, whose operation is analogous to that of the transporting apparatus, is installed in the riser to insure that the latter can convey the mixture through a great distance, e.g., onto a classify-ing conveyor which is located at or above the ground level and permits the liquid to pass therethrough but intercepts the solid particles.

Abstract: "PRODUCTION OF SODIUM DITHIONITE FROM SULFUR DIOXIDE, SODIUM FORMATE, AND SODIUM CARBONATE             WITH MINIMUM SOLVENT"     ABSTRACT OF THE DISCLOSURE         A batch process having high sodium efficiency is described for producing anhydrous sodium dithionite by using minimum amounts of water and methanol while reacting sulfur dioxide with sodium formate and with sodium carbonate.  Based on sodium, yields of pure sodium dithionite exceed 73%, and productivity in terms of pounds per hour per gallon of reactor volume is at least about 0.6.       An improved soda-ash batch process is also described for producing anhydrous sodium dithionite by using minimum amounts of water and methanol while pre-reacting sulfur dioxide with sodium carbonate in methanol and admixing the reaction product, as a methanol slurry, with aqueous sodium formate at up to maximum concentration.  This externally reacted process results in at least 25% greater yield than the standard caustic soda process while consuming less SO2 and less equivalent NaOH.       A second improved process utilizes the reaction product of soda ash with a portion of the sulfur dioxide by adding sodium metabisulfite and about 30% of the sulfur dioxide to the methanol and adding the slurry to the same concentrated aqueous solution of sodium formate while adding the remaining 20% of the sulfur dioxide thereto.  This MBS process produces sodium dithionite having excellent particle size and dust properties at about 20% greater yield than the standard caustic soda process while consuming less equivalent NaOH.

Abstract: ABSTRACT OF THE DISCLOSURE           Vibration sealing apparatus including a vibrating horn and a stationary mandrel having rectangular work faces for oppos-ing each other to seal a rectangular end closure of a thermoplastic coated paperboard carton.  The work face of the vibrating horn de-fines an elongated depression extending between a pair of its op-posite edges with a predetermined depth and also defines a pair of spaced depressions associated with each of the opposite edges.          The spaced depressions have a depth greater than the elongated de-pression and each pair of the spaced depressions forms a pointed configuration that points toward the other pair of spaced depres-sions.  Preferably, the spaced depressions of each pair have the shape of right triangles with the right angle vertices thereof located adjacent the associated edge of the work face in a spaced relationship thereto and adjacent each other in a spaced relation-ship.  One embodiment of the horn has only one of the triangular depressions of each pair overlapping the elongated depression to provide sealing of a "non-tuck-in" carton end closure.  Another embodiment of the work face has both triangular depressions of each pair overlapping the elongated depression to provide sealing of a "tuck-in" carton end closure.  In both horn embodiments, an edge depression extends along one of the edges of the work face from one end of the elongated depression outwardly to one side thereof with the same depth as the elongated depression.  The man-drel work face includes diagonal depressions defining a central junction at which a pair of opposed triangular projections are located.  Preferably, the diagonal depressions of the mandrel work face include offset portions on opposite sides of the junction thereof and have the same depth as the height of the triangular projections and as the depth of the triangular depres-sions on the horn work face.

Abstract: ABSTRACT OF THE DISCLOSURE           A battery-powered fire alarm including a smoke detector, a controllable horn circuit and a battery monitoring circuit.  The smoke detector employs a pair of complementary field-effect transistor switches respectively connected to an ionization chamber and a potentiometer of a Wheatstone bridge circuit connected across the battery.  Unlike known circuits of this type, the field-effect transistors are biased off to minimize standby power consumption and are connected such that the threshold voltages thereof are offsetting to minimize supply voltage sensitivity of the detector.  When the voltage from the ionization chamber assumes a value approximately equal to the potentiometer voltage, both field-effect transistors turn on to energize an alarm circuit to sound an alarm.  Hysteresis circuitry is provided to ensure that the complementary switches, once turned on, will not turn off and thereby terminate the alarm until after the alarm condition has terminated.  The battery monitoring circuit employs a pair of complementary field-effect transistors connected with each other to establish a reference voltage to which the battery voltage is compared.  An advantage over prior battery monitoring circuits of this type is that the reference voltage is a function of both the threshold characteristics of the field-effect transistors and the magnitude of a preselected control voltage.  Both field-effect transistors remain off until a low battery voltage condition is sensed to minimize standby power consumption.
