Abstract: ABSTRACT OF THE DISCLOSURE           A time division multiplex remote control system controls data transmission between a central controller and a plurality of addressable remote terminals coupled to the central controller through a signal line.  The cen-tral controller transmits to each of the terminals a trans-mission signal comprising address data addressing one of the terminals, control data, a reply signal standing-by period defining signal for defining a period for receiving a reply signal from the corresponding terminal, and an interruption request signal standing-by period defining signal for defining a period for receiving an interruption request signal from the terminal.  Each terminal receives the transmission signal and, when the received address data coincides with an address of the terminal, accepts the control data and sends a reply signal during a reply signal standing-by period.  Each terminal further detects a change of a supervisory input which the terminal super-vises and sends an interruption request signal at the timing of the interruption request signal standing-by period of the transmission signal.

Abstract: ABSTRACT OF THE DISCLOSURE           A sheet steel poly-V-grooved pulley having a special cross-sectional contour is made optionally by any one of three different cold working manufacturing procedures.          Special physical properties of characteristics are developed in the pulley by the manner in which the metal in the V-groove body and single and double walled terminal flanges are cold worked.  The cold working involves forming in stages of manu-facturing from a cup-shaped blank to the finished pulley pro-duct a stepped inner body wall surface equivalent to a tapered surface with improved substantially uniform torque transmitting strength in the grooved body from web wall to open end.  Also involved in the cold working is an increase in pulley diameter in certain portions of the finished pulley and a decrease in diameter in other portions from the diameter of the side wall of the cup shaped starting blank.

Abstract: AUTO RANGE HORIZONTAL AUTOMATIC PHASE CONTROL       ABSTRACT OF THE DISCLOSURE     A circuit for phase locking the flyback pulse to a reference signal.  A phase detector receives the flyback pulse (to be phase locked) and receives the ref-erence signal.  It outputs an error signal to a control circuit including first and second differential amplifiers having differing operational characteristics, one being linear in a narrower range than the other.  The differential amplifier having the larger linearity range provides control signals to a coarse delay adjust circuit in the form of a programmable divider which also receives clock pulses at a high multiple of the horizontal frequency fH. The output of the coarse delay adjust circuit is applied to a fine delay adjust circuit responsively connected to the output of the first differential amplifier, which is linear over the narrower range.  The output of the fine delay adjust circuit is coupled to the horizontal system. Large changes in the phase of the flyback signal are achieved by recognizing large deviations in the wider range differential amplifier and causing the coarse delay adjust circuit to make a relatively large adjustment in the phase of the output signals thereof.  Thereafter, fine adjustments are made by the fine delay adjustment circuit in response to control signals from the narrower range differential amplifier.

Abstract: ABSTRACT          An ion generator for use with an electrostatic printer or the like to modify the electrostatic charge on a dielectric receptor surface is described.  The generator includes a plurality of corona wires supported on a rod attached and to the rod.  The wires are spaced angularly about the rod and a protector extends longitudinally around the rod and spaced radially from the wires.  The protector has an axially extending window and an end piece is fixed to an outer end of the rod and journalled  with an end of the protector to allow relative angular movement so that selected ones of the wires can be aligned with the window near the receptor surface.  The window has an annular extent less than the spacing between adjacent wires so that for transportation the rod can be turned in the protector to place the wires to the sides of the window to minimise the risk of damage.         The ion generator can be combined with a housing mounted on the printer and the generator is designed for rotational engagement in the housing.

The shape of a pulse corresponding to the ore body under investigation is compared with the shapes of pulses corresponding to ore bodies of the known mineral composition, and one similar pulse is selected from these pulses. Then a pulse from the burst corresponding to the ore body under investigation is subjected to the Fourier transformation to obtain the pulse height-frequency spect-rum of this pulse, which is compared with the pulse height-frequency spectrum of the selected pulse, and when at le-ast two frequencies of the maximums of the amplitudes of these respective spectra coincide, there is established correspondence between the mineral compositions of the known ore body and of the ore body under investigation.
