Abstract: HYDROSTATIC TRANSMISSION CONTROL SYSTEM          Abstract of the Disclosure:     An improved hydrostatic transmission control system includes two pilot valves which are selectively operable to perform the dual functions of (1) effecting actuation of a main control valve from a neutral position to either one of two actuated positions to port fluid to vary the displacement of the hydrostatic transmission and (2) effecting a change in the rate at which fluid is ported and the displacement of the hydrostatic transmission is varied.  When the displacement of the hydrostatic transmission is to be increased, a first one of the pilot valves is actuated to effect operation of the main control valve from the neutral position to a first actuated position in which fluid is ported to a swashplate motor to effect an increase in the displacement of the hydrostatic transmission.  If a relatively large increase is to be made in the displacement of the hydrostatic transmission, the second pilot valve is also actuated to increase the rate of fluid flow between the main control valve and the swashplate motor.  When the displacement of the hydrostatic transmission is to be decreased, the second pilot valve is actuated to effect operation of the main control valve from the neutral position to a second actuated position in which fluid is ported to the swashplate motor to effect a decrease in the displacement of the hydrostatic transmission.          If a relatively large reduction is to be made in the displace-ment of the hydrostatic transmission, the first pilot valve is also actuated to increase the rate at which fluid is conducted between the main control valve and the swashplate motor.  A control circuit for effecting operation of the two pilot valves to either increase or decrease the displacement of the hydro-static transmission in response to a command signal includes a time delay circuit to effect sequential operation of the two pilot valves when a relatively large change is to be made in the displacement of the hydrostatic transmission.

Abstract: ABSTRACT OF THE DISCLOSURE        The specification discloses a completely automated method and apparatus for producing high tensile steel, of a controlled, predetermined U.T.S. and cross sectional area, from low to medium carbon steel by subjecting the steel to substantial elongation while simultaneously substantially heating and immediately thereafter rapidly quenching the steel, and while continually moving the steel relative to the heating and quenching means employed. The steel is heated to a temperature above its austenite conversion temperature.  Greater elongation produces greater ultimate tensile strength, as much as more than twice as great as the starting ultimate tensile strength, and elongations approaching 200 percent have been effected.

Conductive ring members are positioned adjacent each end of such assembly to fixedly hold the assembly at a predetermined position within the housing to prevent axial movement of the center conductor member therein.  The diameters and lengths of the above members are selected to provide substantially matched impedance characteristics over the length of the coaxial connector.

Abstract: ABSTRACT OF THE DISCLOSURE      An earth boring drill employing roller cutters is provided with a seal in a peripheral groove to inhibit ingress of detritus into the cutter bearing area and engress of lubricant therefrom.          The shape of the seal is such that its cross section is not overly compressed or displaced when in operating position, thus preventing undue compression set, wear and heating of the seal.          A preferred seal has a greater radial dimension than axial dimension by a ratio of at least one-and-one-half to one to conserve bearing space and to provide the necessary flexibility to accommodate the various movements of the cutter relative to the shaft upon which it is rotatably mounted.  The roller cutter has a counterbore fitting over a short cylindrical boss from which the shaft extends on which the cutter is mounted.  This provides a tortuous passage restricting ingress of detritus and substantially improved life of the drill bit.

Abstract: TRANSFORMERLESS TWO-WIRE/FOUR-WIRE HYBRID                WITH DC SOURCING CAPABILITY     ABSTRACT     An electronic hybrid circuit for coupling a two-wire communication path with a four-wire communication path is disclosed wherein the use of transformer coupling is eliminated.  The hybrid features a novel arrangement whereby the unbalanced four-wire path incoming voice signal is amplified, then converted to a pair of balanced signal components by complementary signal injection devices coupled to opposite sides of the two-wire path.  Each resultant balanced component is injected in series with a DC battery feed potential via current amplifiers in each signal injection means.  Balanced two-wire path output signals are converted for transmission to the out-going portion of the four-wire path by coupling the two-wire path to the series combination of a differential amplifier and an output buffer amplifier.  A transhybrid balance network is connected between the output of one of the signal injection devices and the input of the buffer amplifier to prevent the coupling of signals from the incoming portion of the four-wire path from reaching the outgoing portion of the four-wire path.
