Abstract: Abstract of the Disclosure A novel process and apparatus for the preparation of an alkali metal halate by electrolysis of an aqueous alkali metal halide solution.   An alkali metal halide solution is passed upwardly through a plurality of bipolar electrolysis unit while passing an electrolysis current therethrough at a temperature of 90 to 110°C and at a current density to volume ratio of 15 to 30 A/liter to convert at least a portion of the alkali metal halide to alkali metal hypohalite.   The resulting electrolyte is passed, while venting the hydrogen formed, to a reaction zone whose volume is sufficient to provide a residence time to substantially complete the conversion of the alkali metal hypohalite to alkali metal halate and recovering the said halate from the electrolyte and an apparatus for performing the said process.   The bipolar electrolysis units are contained in a vertical electrolysis vessel and the reaction zone is provided by a vertical reaction vessel, the vessels being connected at the tops through a liquid passage with a passage being provided for recycling electrolyte from the reaction vessel bottom to the electrolysis vessel bottom.

Abstract: HYDRAULIC SYSTEM COMBINING OPEN CENTER  AND CLOSED CENTER HYDRAULIC CIRCUITS                 ABSTRACT OF THE DISCLOSURE         A hydraulic system is provided in which a single variable displacement pump supplies the hydraulic fluid requirements of both an open center hydraulic circuit and a closed center hydraulic circuit.  The hydraulic output from the variable displacement pump is delivered to a pressure compensated flow divider which at all times delivers a priority minimum and constant flow to the open center hydraulic circuit despite variations in pump output pressures.  Unless there is a demand for hydraulic flow by a device or devices in the closed center hydraulic circuit, there is no hydraulic flow delivery from the flow divider to the closed center hydraulic circuit, and the variable displacement pump operates at relatively low power input required to supply the demands of the open center hydraulic circuit.  Particularly when the only hydraulic demand on the pump is to satisfy the require-ments of the open center hydraulic circuit in neutral position, the pump can operate on a "standby" basis at a relatively low output pressure, such as 300 pounds per square inch, with consequent low input power to the pump, and with relatively low "wear and tear" on the pump.  The variable displacement pump assembly comprises a hydraulically actuated stroke control means including a tiltably adjustable swash plater and a hydrau-lic compensator for controlling the tilt of the swash plate.  A first pilot circuit is permanently connected between the open center hydraulic circuit and the control input point of the hydraulic compensator which controls the angular position of the tiltably adjustable swash plate, whereby the output pressure of the pump may respond to changes in hydraulic pressure requirements in the open center hydraulic circuit.         A second pilot circuit is connected at one of its ends to the hydraulic conduit which connects the flow divider to the closed center hydraulic circuitry, the opposite end of the second pilot circuit being connected to the control input point of the aforementioned compensator which controls the angular position of the tiltably adjustable swash plate.          The second pilot circuit is completed to communicate a hydraulic input signal to the compensator from the closed center hydraulic circuit only in response to the actuation of at least one closed center device requiring hydraulic flow.  Completion of the second pilot circuit as just mention-ed will supersede the first pilot circuit whereby to cause the compensator to readjust the tiltably adjustable swash plate to cause the pump to supply the substantially higher hydraulic pressure requirements, such as 3,000 pounds per square inch, of the closed center hydraulic system.

Abstract: PATENT SPECIFICATION                 VIBRATORY BIN LEVEL INDICATORS            ABSTRACT     A vibratory system is provided on a wall member which is adapted to form a wall element of a bin or some other receptacle.  The vibratory system comprises inner and outer rod elements secured to and projecting transversely from the inner and outer sides of the wall member, with the axes of the rod members substantially aligned.  In one embodiment, a screw stud extends through the wall member and is connected to the inner and outer rod elements.  Vibrations are induced in the outer rod element by an electromagnet having a coil which is supplied with low frequency electrical pulses.  The magnitude of such vibrations is sensed by sensing the electrical signals induced in the coil due to such vibrations.  A biasing magnetic flux is produced between the electromagnet and the outer rod element so that the vibrations produce variations in the magnetic flux.  The biasing magnetic flux is produced by a permanent magnet or electromagnetically.  The electrical pulses supplied to the coil are at a substantially lower fre-quency than the natural vibration frequency of the outer rod element.  The electrical signals induced in the coil are at or near such natural vibration frequency.  Such electrical signals may be supplied through an amplifier to a comparator for comparing the level of the amplified signals with a reference level, and causing operation of an output device, according to whether or not the level of the amplifed signals exceeds the reference level.  The amplifier may be gated so that it is inactive during the vibration inducing pulses, while being active during the intervals between such pulses.     - i -When the flowable material in the bin or other receptacle engages the inner rod element, the vibrations of the outer rod element are reduced in magnitude.  This reduction causes a change in the state of the ouput device, which may be in the form of an electrical relay adapted to operate a warning device, or to perform any desired control functions.     - ii -

Abstract: Abstract of the Disclosure A radio frequency coupler comprising a first ter-minal for interconnection with a conventional automobile receiving antenna used for receiving rf transmissions within a first radio-frequency band, a second terminal for inter-connection with a receiver operating within the first radio-frequency band and a third terminal for interconnection with a transceiver operating within a second frequency band dif-ferent from the first band.  A first rf transmission path extends between the first terminal and the second terminal and a second rf transmission path extends between the first terminal and the third terminal.  A first resonant circuit is connected in the first rf transmission path and tuned to pass rf transmissions in the first band but substantially block those in the second band.  A second resonant circuit is con-nected in the second rf transmission path and tuned to reso-nate at a frequency within the second band so that rf trans-missions within the second band are passed but those within the first band are substantially blocked.  A third resonant circuit is connected between the third terminal and electri-cal ground and tuned to resonate at a frequency outside the second band.  The second and third resonant circuits form a series-connected path between the first terminal and elec-trical ground and the impedance of the third resonant cir-cuit at the second frequency band allows maximum rf energy within the second band to be transferred between the antenna and the transceiver thereby permitting the conventional automobile receiving antenna normally used only for receiv-ing rf transmissions within the first frequency band to also be used for sending and receiving rf transmissions within the second frequency hand.

Abstract: ABSTRACT OF THE DISCLOSURE           The disclosure relates to a method and apparatus for the operation of a plug mill, in the production of seamless tubes.          Provisions are made for maintaining a circulating supply of plug and mandrel assemblies such that, after a tubular shell from a piercing mill has been given a first pass through the plug mill, the entire combination of the plug and mandrel assembly, and the just-processed shell, are transferred bodily into alignment with the axis of a second stage mill.  The shell is then advanced in the same direction through a second mill stand, over a second plug, while simultaneously being stripped from the first mandrel.          By enabling the shell to be passed through the second plug mill pass, without the requirement of an intermediate operation of stripping the shell from the first stage mandrel, significant time economies are realized.  With conventional plug mill equipment and techniques, the plug mill represents a bottleneck in the se-quence of operations involved in the production of seamless tubing.          In contrast, with the method and apparatus of the invention, the plug mill can easily operate at a greater rate of speed than the piercing mill supplying tubular shells to it.  This is accomplished with only a modest increase in investment in mill equipment.
