Abstract: HIGH VOLTAGE PROTECTION CIRCUIT     ABSTRACT OF THE DISCLOSURE         A horizontal fly-back transformer having a high voltage winding for generating high voltage pulses fed to the anode of a cathode ray tube is provided with a tertiary winding which in turn is connected to a rectifying-smoothing circuit, and a DC voltage in pro-portion to the anode high voltage is obtained from the rectifying-smoothing circuit.  The DC voltage is divided by a resistor divider circuit and a division of the DC voltage is fed to the gate of a thyristor via a Zener diode which is turned on when the anode high voltage exceeds a critical voltage.  A thyristor gate current flow concurrent with conduction of the Zener diode causes the thyristor to turn on so that the operating voltage of a horizontal oscillator circuit may be reduced until the horizontal oscillator circuit stops oscillating, thereby preventing generation of the anode high voltage.          In addition to the aforementioned high voltage preven-tion circuit, a beam current detector circuit is connected in series with the high voltage winding and when the amount of beam current is below a predetermined value, detecting current dependent on the beam current is passed through a part of a resistor circuit.  DC voltage for turning on the Zener diode and accordingly, the anode high voltage in proportion thereto depends on the beam current below the predetermined value so that an anode high voltage level at which the high voltage prevention circuit is operated is varied with the amount of the beam current.

Abstract: TWO-WAY COMMUNICATIONS SYSTEM HAVING REMOTE CHANNEL SELECTION                           ABSTRACT     A channel priority encoder in a mobile/repeater unit of a two-way communications system allows a low power, detached unit to remotely select a desired channel for high power repeater transmission to and reception from a base station.          The selection can be latched-in permanently or can be made to revert to a home channel after a delay.  The mobile unit can override a channel selection made by the detached unit, but another mobile unit would provide the repeater function.

Abstract: ABSTRACT OF THE DISCLOSURE  A method for converter blow end-point control which comprises carrying out waste gas analyses on a continuous or intermittent basis in a final stage of the blow and, based on decarburization rate data (waste gas information) obtained from said waste gas analysis, determining the end-point of the blow where the carbon content of the bath equals a target carbon content.  The method is characterized by the use of the decarburization rate equation:                   which is a differential equation taking account of the delay time (T) of said waste gas in-formation which is a period of time from the time-point of occurrence of a decarburization reaction in the converter till the time when it is detected as said decarburization rate data, and an equation: b'=g(b) which is a functional equation for increasing the predictability of carbon content of the bath at the end-point of the blow.

Abstract: ABSTRACT Of THE DISCLOSURE          A method and apparatus for determining the capacity of lead acid storage batteries are disclosed.  The battery's initial open circuit voltage is stored in a settable memory.  Thereafter, the open circuit voltage values of the battery throughout the discharge period are determined by measuring loaded voltages with reference to the stored open circuit voltages to detect the discharge rates.  The rates of discharge are used to reset the stored value of the initial open circuit voltage measurement thereby producing a moving reference.  The memory output value is a function of the capacity of the battery.  During the charge period, the charge voltages are measured with reference to the stored open circuit voltages to detect the charge rates.  The rates of charge are used to reset the stored value of an initial open circuit voltage measurement.  Again, the memory output value is a function of the capacity of the battery. 1.
