Abstract: ABSTRACT OF THE DISCLOSURE A motor circuit interrupter characterized by a manually operated fast-acting switch and a bi-metallic overload relay for trip opening of the switch contacts in response to current overloads.  The switch comprises means for moving electric contacts between open and closed positions which means includes a releasable arm which is movable between latched and unlatched positions.  When in the "unlatched" condition, the contacts are open and the operating means cannot be operated to effect a re-closing of the contacts.  The switch further comprises a pivoted latch lever operatively connected to the releasable arm to retain the arm in the latched condition, or for effecting unlatching of the arm, a latch retainer lever to retain the latch lever in the latch position said retainer lever is operatively connected to the trip plate of the overload relay to effect unlatching of the latch lever and releasable arm in response to an overload current.  The retainer lever is spring-biased to the latch position with the latch lever and the retainer lever comprising an extension engageable with the latch lever when the latter is in the unlatched position to maintain the latch lever in a relatching position.

Abstract: ABSTRACT       In seismic group recording, each seismic trace is initially digitally recorded by a small, portable, magnetic recorder placed near the corresponding seismometer group.  A large number of such groups and corresponding recorders are placed over an areas or along a profile line, and from a control point, only those specific recorders needed for a given set of record traces are turned on at any time by transmitting a set of coded signals over a communications link which is usually a radio link.  The bandwidth restrictions of licensed geophysical radio channels can cause difficulty in this communications system from control point to the various seismometer groups.  Accordingly, this disclosure covers an improvement in the communication method employed in a seismic group recorder system.  U.S. Patent 3,806,864 teaches the employment of audio frequency encoding on a frequency-modulated band-limited channel with a maximum audio frequency of approximately 3 kilohertz.  As initially used, on-off keying of three different tones was employed, due to simplicity. The present system is an improvement employing coherent frequency-shift keying, in which several different audio frequencies, bearing certain relations to each other, are employed.  This results in near optimum communication for control of the seismic group recorder system over a voice-grade standard, geophysical licensed radio link.

Abstract: FLOODING WITH MICELLAR DISPERSIONS HAVING      CONNATE WATER COMPATIBILITY            ABSTRACT OF THE DISCLOSURE      Improved flooding of a subterranean formation con-taining connate water of a particular salinity with a micellar dispersion comprised of surfactant, water, hydro-carbon, cosurfactant and optionally electrolyte is obtained by designing the cosurfactant(s) within the micellar dis-persion to be more hydrophilic with an increase in salinity and also designing the cosurfactant to permit the micellar dispersion to solubilize at most a minimum amount of the connate water.  Preferably, the cosurfactant is preselected to impart the desired compatibility of the dispersion with the salinity of the connate water or a cosurfactant can be blended with another cosurfactant to obtain the desired viscosity of the micellar dispersion and desired compati-bility with the connate water.  Generally speaking, the cosurfactant should have an increasing hydrophilicy as the salinity of the connate water increases.

Abstract: ABSTRACT         A process for making tubes, channels and other relatively thin-walled elongated shapes having a unique degree of dimensional accuracy and stability in which the part after being shaped and only approximately sized is mounted on a mandrel having a larger coefficient of thermal expansion than the part.  The mandrel and the part are connected at their opposite ends so that expansion of the mandrel first causes elongation and concomitant lateral shrinkage of the part and then lateral expansion of the part so that it is triaxially hot worked to bring it to its final hot size from which the part contracts to its finished size at room temperature.  For maximum freedom from residual stresses and dimensional stability thermal sizing is carried out by heating to a temperature at least just above the recrystallization temperature of the part.

Abstract: STEERING CLUTCH AND SINGLE PEDAL BRAKE   CONTROL SYSTEM FOR CRAWLER TRACTOR                          ABSTRACT           A crawler tractor has an engine-driven transmission for supplying motive power to the left and right crawler tracks through spring-applied fluid-released left and right steering clutches and also has spring-applied fluid-released track brakes.          A hydraulic steering clutch and brake control system is provided and includes left and right manually operable steering levers for the clutches and a single foot-operated brake pedal.  The control system further includes a single pump for supplying hydraulic fluid to the steering clutches and to the brake actua-tors for the brakes.  A steering valve, having a flow divider therein, receives fluid from the pump and is responsive to actua-tion of the steering levers to supply fluid to release the steer-ing clutches.  The steering valve also continually directs fluid to a pilot operated shuttle valve which is responsive to operation of the steering clutches to direct operating fluid to the brake actuators to effect brake release for that track whose clutch is engaged.  A combined pressure relief valve, brake valve and brake inhibitor valve is provided and operates in response to the brake pedal and is also responsive to fluid pressure in the tractor transmission.  The control system operates so that actua-tion of either steering lever from neutral effects fluid release of its associated steering clutch, whereupon depression of the single brake pedal will then operate the combined valve to effect spring application of the brake for that track whose clutch is released.  If both steering levers are in neutral and trans-mission fluid pressure drops below a predetermined value, as during reverse shifting to change direction of tractor travel, the combined valve effects automatic spring-application of both brakes, without loss of fluid pressure necessary for control of the steering clutches.

Abstract: ABSTRACT OF THE DISCLOSURE          The quality and useful life of regnerative-cycle type incandescent lamps that employ iodine as the halogen are enhanced by dosing the lamps with controlled amounts of SnI4 in combination with elemental iodine.  Alternative dual-additives that provide iodine-bromine type lamps are SnI4 in combination with a compound such as methylene bromide (CH2Br2) or mercury bromide which decompose within the energized lamp and release free bromine, and mercury iodide in combination with CH2Br2.  The combined use of two different additives or dosing materials to provide either an iodine or an iodine-bromine atmosphere within the operating lamp permits elongated tubular lamps having singly-coiled filaments to be operated in various non-horizontal burning positions at voltages above their nominal voltage ratings for much longer periods of time than lamps of the same rating and construction that are dosed with a single addi-tive such as elemental iodine, SnI4 or CH2Br2.
