Patent number: 5188494Abstract: The present invention is a torque indicator device that provides a positive indication as to whether or not a threaded fastener has been tightened to a desired torque. The present invention torque indicator device is mounted under the head of a threaded fastener and is shaped so that the indicator device is displaced from beneath the threaded fastener's head as the threaded fastener is tightened to a predetermined torque. As the threaded fastener is tightened to a predetermined torque, the brightly colored indicator device falls away from the threaded fastener giving an easily observed positive indication as to whether the threaded fastener has been properly tightened.Type: GrantFiled: April 21, 1992Date of Patent: February 23, 1993Assignee: ITT CorporationInventor: Donald T.

Patent number: 5188203Abstract: An improved disc brake rotor is formed with fins extending between the two annular braking members which are elongated tangentially of the rotor axis and disposed in two groups lying at different radial distances from the axis. The tangential orientation of the fins minimizes the amount of material required to form the fins while achieving structural rigidity comparable to other fin arrangements which require substantially more material. The fin arrangements disclosed thus enables a substantial reduction in weight and also achieves efficient cooling air flow patterns for either direction of rotation of the rotor.Type: GrantFiled: September 26, 1990Date of Patent: February 23, 1993Assignee: ITT CorporationInventor: Klaus Winter

Patent number: 5182525Abstract: A CMOS transconductance amplifier with a floating operating point which has low quiescent-current consumption for a voltage-to-current converter. On the other hand, the current yield of the output transistor in an output current mirror for a load current is high. The low quiescent-current consumption is achieved by connecting a coupling transistor used as a low-impedance diode in parallel with an active load in the current output stage of the voltage-to-current converter. The high current yield is achieved by means of a positive-feedback circuit which adds to the quiescent current of the voltage-to-current converter an auxiliary current proportional to the load current, thus forming a floating operating point.Type: GrantFiled: December 9, 1991Date of Patent: January 26, 1993Assignee: Deutsche ITT Industries GmbHInventor: Ulrich Theus

Patent number: 5181115Abstract: A digital phase-locked loop has a periodically overflowing digital oscillator (DCO), implemented as a modulo adder, and a processor device. The processor device adjusts the period T of the digital oscillator to a nominal period, determined from periodically occurring synchronizing pulses, by comparing the actual phase of the digital oscillator with a set phase at the control clock rate of the periodic synchronizing pulses. After the digital oscillator has been locked to the nominal period, the processor device compares the phases by using a double-frequency signal sequence of one-half line period derived from the digital oscillator output signal. The DCO output signal is fed to a correction device where an address-phase signal, locked to the DCO output signal, is generated so that when a non-periodic synchronizing pulse occurs, the address-phase signal is shifted by one period of the signal sequence of one-half line period with respect to the digital oscillator output signal.Type: GrantFiled: June 21, 1991Date of Patent: January 19, 1993Assignee: Deutsche ITT Industries GmbHInventors: Peter Flamm, Martin Winterer, Hans-Juergen Desor

Patent number: 5180998Abstract: A reflection-type phase shifter employs an artificial delay line which is constructed of high impedance transmission line sections for the series inductive elements in the transmission line. Each junction between inductances in the transmission line is associated with a separate FET pair. The FET pair includes a first FET having the source to drain path coupled between the junction and a point of reference potential. The gate electrode of the first FET is coupled via the source to drain path of a second FET to the point of reference potential. The gate electrode of the second FET is coupled to one terminal of a resistor which is of a larger value compared to the ON resistance of the FET. This resistor has another terminal coupled to a control voltage source.Type: GrantFiled: November 5, 1991Date of Patent: January 19, 1993Assignee: ITT CorporationInventor: David A. Willems

Patent number: 5178424Abstract: An insertion indication device for use with a quick connect fitting includes a generally annular base member which is adapted for positioning about a male conduit inside of a connector housing. One or more leg members extend axially from the base member and terminate near an axial opening formed in the housing for receiving the conduit. A generally annular indicator member positioned adjacent to the opening releassably engages the end members. Upon couplings of the male and female elements of the quick connector, the indicator member is separated from the leg members to provide visual conformation that coupling has taken place.Type: GrantFiled: July 1, 1991Date of Patent: January 12, 1993Assignee: ITT CorporationInventor: Gary Klinger
