Abstract: A CODED RECORD AND METHODS OF AND APPARATUS      FOR ENCODING AND DECODING RECORDS     Abstract of the Disclosure A novel record with alternate width modulated bars and spaces is decoded by comparing the width of each bar or space with a pair of reference values based on the product and quotient of a constant and the width of another bar or space to establish bit value.  When the width value is greater or less than the reference value, the bit value is established.          When the width values lie between the reference values, a state of equality is established which is resolved into a bit value by reference to the results of a prior or subsequent comparison.  A system embodying the method includes storage means for storing width values, reference registers for establishing successive different sets of product and quotient reference values, and comparators controlled by the stored width and reference values for establishing the greater and less than and equality status conditions. In one embodiment, a shift register and logic circuits controlled by the status conditions provide dynamic interpretation of the status conditions into code bits as the character is read.          In another embodiment, the status conditions are stored and then translated into code bits after a complete character has been read.  In one code set, each character code of seven bits formed by four bars and three spaces uses five bits to define the character and the remaining two bits to provide separate bar  and space parity bits. This and the fact that only one space "1" and one bar "1" are included in a proper code results in a code with an extremely low expected rate of undetected error.  The system also includes separate parity check circuits for the decoded bar and space bits.

Abstract: 47,664 PROCESS FOR RECOVERING URANIUM AND          OTHER BASE METALS     ABSTRACT OF THE DISCLOSURE Uranium and other base metals are leached from their ores with aqueous solutions containing bicarbonate ions that have been generated or reconstituted by converting other non-bicarbonate anions into bicarbonate ions.  The conversion is most conveniently effected by contacting solutions containing S04 = and Cl - ions with a basic anion exchange resin so that the S04 = and Cl - ions are converted into or exchanged for HC03 - ions.  CO2 may be dissolved in the solutions so it is present during the exchange.  The resin is preferably in bicarbonate form prior to contact and CO2 partial pressure is adjusted so that the resin is not fouled by depositing metal precipitates.  In-situ uranium mining is conducted by circulating such solutions through the ore deposit. Oxidizing agents are included in the injected lixiviant. The leaching strength of the circulating bicarbonate lixiviant is maintained by converting the anions generated during leaching or above ground recovery processes into HC03 - ions. The resin may conveniently be eluted and reformed intermittently.

Abstract: A TRACTOR DRAFT LOAD MONITORING SYSTEM   ABSTRACT OF THE DISCLOSURE      A tractor draft load monitoring system responsive to tractor and associated implement load changes.  The system is particularly adapted for a tractor having an engine/trans-mission power unit coupled to its drive shaft.  The power unit is mounted on the frame by resilient mounts that permit measurable angular displacement of the power unit relative to the frame about the drive shaft axis in reaction to changes in the drive shaft torque.  The working depth of the implement, which may be tractor mounted, semi-mounted or a pull type implement, is raised or lowered by a hydraulic lift system that is controlled by a control valve assembly connected to a source of fluid under pressure.  Interposed between the power unit and the control valve assembly is a transmission cable (Bowden wire type) and lever system that is operative to transmit angular displacement of the power unit to an actuating member of the control valve assembly to cause hydraulic actuation of the hydraulic lift device to change the working depth of the implement to compensate for changes in its draft load.

Abstract: ABSTRACT A plough has right-hand and left-hand ploughshare pairs mounted on a swing-over saddle frame extending backwards diagonally with respect to the direction of advance.  The frame is supported by a 2-wheeled carriage by means of a T-frame which provides two axes of rotation perpendicular to each other.  Two single-acting, swing-over cylinders are each pivoted at the bot-tom end to the T-frame on a fore-and-aft pivot axis and connected at the top end with the saddle frame.  The cylinders rise upwards so that their pistons approach each other in inverted V-formation.  The upper ends of the pistons work in guiding slots in plates of a guiding system fixed to a middle portion of the saddle frame and in further slots in cheek plates of a rocker.  This rocker pilots on a fore-and-aft axis of the T-frame.  The T-frame and/or the carriage has supports for the saddle frame in its various positions.
