  • Patent number: 4019142
    Abstract: The receiver includes a decoder responsive to certain characteristics of a coded signal, such as the frequency of tones, for producing a decoded signal indicative of second characteristics of the coded signal, such as the durations of the tones. A duration detector is responsive to the decoded signal to provide a detected signal having properties indicative of the tone duration. A utilization circuit is coupled to the detector and is operated in accordance with the properties of the detected signal. The utilization circuit may be an annunciator which produces an audible or visual alerting signal, or it may express digital information, or it may be a system which is to be remotely controlled. Such receiver may be one in a system of various groups of receivers which can be contacted simultaneously if desired.

  • Patent number: 4012596
    Abstract: Electronic patch circuitry interconnects a wire telephone line with the base station transmitter and receiver of a simplex two-way radio communication system, for causing VOX-type operation with very fast voice-operated keying between transmitter and receiver. The system is operable in a telephone line priority mode in which it responds to telephone line audio signals for keying the transmitter on and the receiver off regardless of whether or not the receiver is on at the time, and is also operable in an "anti-VOX" mode. An automatic telephone line connector circuit responds to telephone ringing signals on the telephone line at the base station. The circuit then transmits a coded signal to a remote radio transceiver, which can return a signal to "answer" the base station telephone and connect it to the patch circuitry. Automatic dialing means are provided for initiating a telephone call from the remote radio transceiver.

  • Patent number: 4008960
    Abstract: The photoelastic strain gauge coating comprises a sheet of photoelastic material of predetermined shape having a multiplicity of minute discontinuities or sets of discontinuities arranged in a predetermined grid. The predetermined shape and grid, together with boundary devices, provide a standard format to enable use of supporting computer programs. In practicing the method, the coating is bonded to the workpiece surface to be analyzed, and then illuminated by polarized light and photographed. The photograph is then magnified greatly to enable examination seriatim of the patterns at and about each discontinuity or set of discontinuities. The data thus obtained is processed, using the supporting computer programs to obtain a strain field of the portion of the workpiece covered by the coating.

  • Patent number: 4007766
    Abstract: A railway tank car is provided for interconnection in fluid communication with associated tank cars. Each of the tank cars includes a tank mounted on a chassis structure with two lading conduits respectively coupled to the tank, each having an outer end extending outwardly from the tank adjacent to the top thereof and at least one having an inner end extending into the tank and terminating near the bottom thereof. A vapor vent is connected to the tank to vent gas vapors produced during loading. The vent is closed by a valve actuated by a control mechanism in response to a level sensing means which determines the level of liquid lading in the tank. The tank car or train may be loaded or unloaded from either end thereof since the cars can have symmetrical internal piping, and, similarly the gas vapor may be collected from either end of the tank car or train.
