Abstract: ABSTRACT OF THE DISCLOSURE     In the mining of subsurface friable mineral ore deposits, the invention provides a mine configuration and mining system wherein the mine has preferably three levels.  The first operating level, is positioned sub-stantially at the base of the deposit and has an interconnecting system of tunnels within which, mining apparatus operates.  This level further in cludes conveyors adapted to receive loose ore and transport same to ver-tical shafts or ore passes which interconnect adjacent operating levels.          The second operating level is primarily a collecting level, and is pos-itioned below the first, or mining level, to be parallel therewith.  This second level has a tunnel system operatively associated with the vertical ore passes of the first level, and has conveyors which collect the loose ore and carry same to shafts for transport to a final, lower lever, from which the ore is removed from the mine.  According to the invention, ac-tive mining is carried out by the known "Fixed Arch Shield" technique on only one level, the only other levels being ore collecting and haulage levels.  There are no levels, or mine workings, above the first, mining level, only access and ventilation shafts.  By utilizing this mining method and the preferred mine configuration, a complete ore deposit can be removed with minimal surface disturbance, and subsidence can be com-pensated for by distributing waste in a manner that is esthetically acceptable.

Abstract: POWER STEERING SYSTEM          Abstract of the Disclosure A vehicle steering system wherein a manual steering gear output controls actuation of a linear hydraulic motor.          A control valve, which distributes fluid to and from the boost cylinder, is disposed between the pitman shaft and pitman arm of the manual steering gear.  Rotation of the pitman shaft, in response to operator input, causes rotation of the control valve which directs fluid pressure to the hydraulic motor to provide steering assist.  The fluid pressure is also directed, through the control valve, to selectively operate on hydraulic reaction members so that a force proportional to steering effort is transmitted back to the operator.  A mechanical "overcenter feel" is also provided and has incorporated therewith a mechanical override to provide full manual steering when there is not sufficient fluid pressure to provide hydraulic assist for steering.

Abstract: ABSTRACT OF THE DISCLOSURE              Improvements are provided in a catalytic process for purifying terephthalic acid which has been prepared by the catalytic oxidation of p-xylene and which includes 4-carboxybenzaldehyde and terephthaldehyde as aldehydic impurities.  The purification process involves catalytically hydrogenating the impure terephthalic acid to convert 4-carboxybenzaldehyde and terephthaldehyde therein to p-toluic acid and p-xylene, respectively, by a reaction mechanism which involves first converting the aldehyde (CHO) groups to alcohol (CH2OH) groups and then converting the latter to methyl (CH3) groups.  The invention comprises carrying out the hydrogenation of the impure terephthalic acid by contacting an aqueous solution of the impure acid with hydrogen gas, as the sole gaseous reactant, in the presence of a catalyst selected from one of the following metal combinations:  palladium:ruthenium; palladium:osmium; palladium:iridium; palladium:rhodium; palladium:platinum; palladium:rhodium; palladium:iron; palladium:nickel; palladium:cobalt; palladium:chromium; palladium:manganese; and palladium:uranium.  The catalyst functions to improve the speed at which the alcohol groups are converted to methyl groups without markedly affecting the speed of the initial conversion of aldehyde groups to alcohol groups. The terephthalic acid so produced is of sufficient purity for use in the production of polyester fibres.

Abstract: ABSTRACT            A displaying measuring instrument with combined digital and analog display. The lowest order digit of the measuring value to be displayed is indicated by means of a linear scale made up of scale marks, the mark corresponding to the instantaneous value of the measuring value differing in appearance from the surrounding, thus indicating the instantaneous value of the lowest order digit. The higher order digits of the measuring value are displayed by conventional numeral indicators located at the lower end of the linear scale. Thus, the higher order digits are displayed strictly digitally, whereas the lowest order digit is displayed both digitally (by the particular scale mark concerned) and analogously (by the location along the scale of that particular scale mark).
