Abstract: ABSTRACT OF THE DISCLOSURE         A process and an apparatus for on-track truing of the surface of the head of rails of a railway.  A predetermined num-ber of truing tools are oriented according to tangents to the profile of the head and are moved along the generatrices of the surface.  The value of at least one of the parameters influenc-ing the metal removing capability of at least one truing  tool -such as its bearing pressure, its cut speed its inclination angle and its speed of displacement along the rail - is under the control of a set control value which is preestablished as a function of the desired cutting depth of the tool.  There is determined at least one magnitude value representative of the state of the rail head before truing such as the mean amplitude of the undulatory deformation of short wavelength, and/or the amplitude of the undulatory deformations of long wavelength and/or the amplitude of the defects in the profile of the rail head   The control value is set so as to obtain the desired cutt-ing depth of the tool and/or to position it, in function of the measured value of the magnitude and of known values correspond-ing to its metal removing cability.  The setting of the control value is ajusted according to the results obtained at the end of a rail length corresponding at least to the length taken up by the whole assembly of truing tools used.

Abstract: ABSTRACT OF THE DISCLOSURE            A planetary-type lapping machine comprises a station-ary and a rotary lapping discs, and cages arranged therebetween, the cages being essentially planet pinions of a sun-and-planet mechanism and containing the components being machined.          The rotary lapping disc is in a force transmitting connection with the sun gear through a differential gear link.          The differential gear link enables approximately double increase in the angular speed of the lapping disc relative to the angular speed of rotation of the center of said cages about the axis of rotation of said lapping disc.          This relieves the cages from forces applied on the part of the plates being machined.          To maintain parallelism of the lapping discs incor-porated in the drive link of one of the sun gears is a controll-able differential gear link whereby the speed of rotation of the sun gear is varied per cycle.

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.
