Abstract: ABSTRACT OF THE DISCLOSURE      An impact drilling tool for rotary drilling which includes a reciprocating hammer inside a casing for striking the top of an anvil.  A drilling bit is connected to the opposite end of of anvil for cutting into the earth's formations.  The casing is connected in a string of drilling pipe through which a high pressure fluid flows for operating the hammer and removing cuttings.  A feeder means extends through the hammer for alternately directing the high pressure fluid above and below the hammer which high pressure fluid causes the reciprocating motion of the hammer.  A shuttle valve located around the feeder maintains communication of the high pressure fluid above the hammer for increased effective stroke to insure a harder driving action of the hammer against the anvil.  Also the shuttle valve insures a more complete exhaust above the hammer which reduces the force needed to raise the hammer.  In alternative embodiments, the shuttle may control only one of the exhaust or pressurization functions.

Abstract: LATCH RELEASING MECHANISM FOR        WATER SAMPLES     ABSTRACT OF THE DISCLOSURE                A Kemmerer style water sampler has a tubular body open at both ends and through which extends a connect-ing rod.  The lower end of the connecting rod is fixed to a closure for the lower end of the body.  The upper end of the connecting rod is releasably latched to an upper closure and carries a latch member which is engageable by and disengage-able from a pair of clasp members mounted on the upper closure for movements in directions into and out of latching position.  Each clasp member is provided with an upstanding motion transmitting member having inclined, confronting sur-faces spaced apart to provide a chamber.  Reciprocably accommodated in the chamber is an operating member that is tapered complementally to the inclination of the surfaces of the motion transmitting members so that movement of the operating member axially in one direction effects movement of the clasp members out of latching engagement with the latch member, thereby enabling the upper and lower closures to seal the opposite ends of the body.

Abstract: ABSTRACT OF THE DISCLOSURE           Control of test chambers or specimens to stabilized temperatures at set points over a wide temperature range is accomplished with improved response time by an arrangement of cascaded Peltier affect heat pumps.      Generally, power to a first Peltier unit in the arrangement is controlled relatively to the temperature deviation of the specimen from the desired set point, while power to a second Peltier unit therein is controlled proportionally to the temperature differential across the first Peltier unit.  In applications where large thermal losses to ambient occur, a portion of the power control signal to the second Peltier unit is applied to offset the temperature set point as a compensation for such losses. improvement in approach to stabilized temperature is further attained by applying an anticipation signal in proportion to the temperature gradient between the specimen and the first Peltier unit to decrease the monitored deviation of the specimen temperature from the set point.  For system pro-tecion the power control signals to the Peltier units are shut off to preclude thermal runaway in applications where the specimen temperature is monitored by a sensor which must be exposed to ambient conditions during set-up periods.

Abstract: NMR MAGNET ASSEMBLY WITH POLE FACE PARALLELISM                 ADJUSTMENT               Abstract Of The Disclosure A nuclear magnetic resonance (NMR) magnet assembly includes two pole faces spaced to provide a gap in which is established a uniform magnetic field.  The pole pieces have pole faces that are flat and parallel.  The pole pieces are mounted on support plates one of which is fixed and the other of which is movable about a pivot point with two degrees of freedom of movement in response to adjustment of two adjustable mechanisms.  Each adjustment mechanism includes a differential screw that produces a transverse movement and a longitudinally inclined pin or pins that translates such transverse movement into a much greatly reduced longitudinal movement.  The combination of a differential screw and inclined pin provides a very fine adjustment of the parallelism of the pole faces.  Each mechanism further includes means for providing a coarse adjustment.

Abstract: FLOW DIVERTER PRESSURE PLATE                          ABSTRACT A gear pump or motor capable of sustained operation under unusually high pressure conditions is provided with at least one unique pressure-balancing diverter plate having pressure-transmitting paths extending around the outer peri-pheral edges of the plate between terminating locations on the high and low pressure sides of the pump.  The termi-nating locations on the low pressure side of the pump are open on the gear tooth confronting face of the plate and are exposed to interdental spaces of the impellers adjacent to but spaced and isolated from the low pressure port.          The terminating locations on the high pressure side of the pump provide fluid pressure communication with the high pressure port during operation of the pump or motor.  In operation, the outlet pressure is transmitted through the specially formed paths to areas of the gears on the low pressure side.  The transmitted pressure acts as a counter-force that pushes the gears towards a center position and reduces bearing loads.

Title: Cathodic electrodeposition of polyamine resins using carbonic acid neutralization

Granted: 1980-04-01
Abstract: ABSTRACT OF THE DISCLOSURE         A simplified method for the cathodic electro-deposition of polyamine resin from a dispersion thereof in an aqueous electrocoating bath is provided in which the polyamine is selected to be stably dispersible in water in the form of a salt with a solubilizing acid at a pH of from 6.0-7.5, and this polyamine resin is substantially completely neutralized with carbonic acid and dispersed in water in the form of an amine carbonate or bicarbonate.  A unidirectional electrical current is passed through an aqueous electrocoating bath containing the amine carbonate or bicarbonate to deposit the polyamine resin at the cathode and cause the release of carbon dioxide.  In preferred prac-tice, a proportion of the amine groups in the polyamine resin within the bath, low enough to maintain the pH of the bath at a pH of about 6.0 or higher, is reacted with a relatively nonvolatile solubilizing acid, and the polyamine resin solids in the electrocoating bath are replenished by adding to the bath polyamine resin substantially completely neutralized with carbonic acid.

Abstract: ABSTRACT OF THE DISCLOSURE        A ball valve has a valve body and a ball shaped closure mounted on spindles which extend at right angles to the flow passage in the body. The spindle is sealed to the valve body by bellows-shaped, accordion-like or plaited sealing means dimesioned to with stand the pipe pressure in the valve, but nevertheless sufficiently flexible to permit tipping of the closure in response to pressure in the valve or to manipulation of the spindle from outside the valve about the spindle end situated on the opposite side of the closure.  The tipping movement can occur when the pipe pressure acting on the closure is exceptionally high, and the closure can be turned from outside the valve from tipped position towards a position where the spindles are at right angles to the flow passage of the valve, so that the closure can be rotated at a lower torque to desired position.

Abstract: PLOW SYSTEM               ABSTRACT OF THE DISCLOSURE       A variable width furrow-spacing plow system em-bodied in an implement having a laterally adjustable tractor hitch, an angularly adjustable plow-carrying main frame, and hydraulic means for correlating the lateral movements of the hitch and angular position of the frame, to the end that for any given furrow spacing the hitch point of the implement will fall closer to the line of pull than has heretofore been possible, and minimum pulling force will be required to motivate the implement.  The system embodies a pull bar or frame which has its forward end pivoted to the adjustable tractor hitch and its rear end pivoted to a medial region of the plow-carrying frame.  A hydraulic ram controls the lateral adjustment of the hitch, while a second ram controls the angularity between the pull frame and the main frame.          The two rams are phased for operation in unison under the control of a valve in the cab of the tractor.  A third ram which also is phased with the two other rams, controls the attitude of a trailer section, and maintains such section in line with the direction of travel of the tractor.
