    摘要: A screw-in station protector assembly includes a carrier housing containing a shorting cage which is biased by a compression to urge the cage and gas tube arrester assembly outwardly. The gas tube assembly contained within the cage includes a two electrode gas tube and a sealed external back-up air gap protector. The screw-in-assembly is particularly adapted for retro-fitting/replacement of carbon block arresters without modification.

    摘要: Disclosed herein are surge arrester configurations employing non-metallic and preferably plastic fusible elements which normally insulate biased short circuiting members from shorting the surge arrester but which, in the event of certain forms of excessive overloads, fuse to thereby permit the shorting elements to short circuit the arrester gap. In addition, the embodiments include integral backup air gaps to provide additional backup protection covering certain gas tube failure modes. In the illustrated embodiments, the shorting elements each take the form of a conductive clip with one set of spring fingers in electrical contact with the line (end) electrode and another set urged in the direction of the ground electrode but separated therefrom by an annular plastic fusible sleeve coaxially coupled to the center body housing. Fusion of the sleeve in the presence of a sustained overload causes it to yield, thereby permitting the respective spring fingers to move into contact with the ground electrode, causing a short circuit.

    摘要: A plural channel amplitude modulated frequency division multiplexed station carrier system wherein the receivers of the subscriber and central office channel terminal circuits are each equipped with a bandpass filter which is tuned to the carrier frequency to be received and with a circuit for synchronously detecting the carrier signal to which the bandpass filter is tuned. In the subscriber channel terminal circuits the bandpass filters are of the first order type, and in the central office channel terminal circuits the order of each bandpass filter is no greater than two. Carrier signal level adjustment is provided at the subscribers' end of the carrier system's transmission line for the purpose of causing all of the central office transmitted carrier signals to arrive at the subscriber channel terminal receivers at or at least approximately at a common level and for the additional purpose of causing all of the subscriber transmitted carrier signals to arrive at the central office channel terminal receivers at or at least approximately at a common level.

    摘要: A three phase power ozonator system in which the head of an ozonator cell containing multiple cylindrical type elements is tri-partitioned to define three sectors in the cell each of which contains a portion of the total number of cylindrical type dielectric elements. The partitions are made of insulating material such as polyvinyl chloride. Each sector is distinct and each sector is adapted to be operated with single phase electrical power. As a result the ozonator cell as a whole is able to operate using three phase electrical power. This arrangement allows for the operation of the ozonator cell in a system having any number of other three phase electrically operated components of equal or smaller electrical load than the ozonator cell in such a way that a balanced electrical load is maintained throughout the system.An electrical supply and control sub-system including a three phase power transformer, current sensors for each electrical sector and voltage sensor for one sector, current and voltage comparators and a variable transformer driven by a reversible electric motor, provides current to the electrodes in all sectors, monitors the current in all phases and turns off the electrical supply if significant imbalances among the sectors are detected.

    摘要: A signal-amplifying telephone carrier repeater which is automatically self-adjusting for both cable length and cable gauge in a plural channel, frequency division multiplexed, amplitude modulated carrier system. Also disclosed herein is a subscriber power supply which delivers sufficient power to the subscriber terminal load despite variations in load current due to changes in the number of channels in the carrier system. The power supply also has a back-up unit which operates to deliver power to the load in the event that a fault occurs in the primary supply.

    摘要: A foam removal apparatus for a vessel which contains a liquid as well as foam bubbles has a cover inclined with respect to the horizontal, a screen, and a trough, the trough being located beneath at least a portion of the screen for removing foam pushed through said screen. The apparatus can be used in conjunction with any shaped vessel and requires no energy for foam removal. Either a rising liquid level in the vessel or a continuous generation of foam forces the foam against the inclined cover and through the screen which causes a substantial amount of foam bubbles to collapse and fall as liquid into the trough.
