Abstract: ABSTRACT OF THE DISCLOSURE        An ice lubrication system for easing the passage of a ship through ice laden waters.  A pressurized flow of water passes through a nozzle into the inlet of a mixing chamber comprising a venturi where gas from a gas manifold is mixed with the water.  The effect of the venturi is to first cause the gas to mix into the water flow and, after passage of the flow through the venturi, to cause the gas to emerge from the water.  A frothy combination of gas bubbles and water is thus created which is discharged through openings in the ship's hull below the waterline. Once discharged, the gas and water combination rises up the side of the hull to provide separation and lubrication between the hull and floating ice.

Abstract: ABSTRACT      An optical fiber tap which is especially useful as a node in a local area network, especially a ring topology local area network.  The tap, which does not interrupt the physical continuity of the fiber, has an open position and a closed position.  In the open position, a signal passing down the optical fiber passes through the tap without alteration.  In the closed position, a signal passing down the optical fiber is extracted through a first bend which is put into the fiber by the tap; the extracted signal, or an electrical counterpart thereof, is processed and a counterpart of the extracted signal, or a new signal obtained by operating on the extracted signal, e.g. in a data processor, is injected into the fiber through a second bend which is put into the fiber by the tap.  The tap may also contain an attenuator between the signal extractor and injector, so that only that signal injected by the tap propagates down the fiber beyond the tap.

Abstract: ABSTRACT OF THE DISCLOSURE    Magnesium metal  is  formed by  the  silicothermic method in a manner which is a substantial improvement over prior  art processes.   Magnesium oxide,  calcium oxide and silicon are reacted in a heated flowing inert gas  stream,  for  example,  hydrogen,  argon or helium, which maintains the reaction temperature and removes gaseous magnesium from the reaction zone.  Magnesium is recovered from the inert gas stream in liquid or solid form by cooling.  Heat recovery is effected to preserve thermal efficiency and the inert gas stream is recycled to  the  reaction  zone.   Continuous  production  of magnesium can be effected.

Abstract: ABSTRACT OF THE DISCLOSURE               An improved control system and method for maintaining the outlet temperature of a process fluid exiting from a process fluid coil located in the convection section of a boiler having a convection section and a radiant section.  The improved control system and appara-tus comprise means for measuring the inlet temperature and the flow rate of a process fluid to the process fluid coil and means for measuring the temperature of the process fluid at the outlet of the process fluid coil. The improved control method and apparatus also comprise a first means responsive to changes in the inlet temperatures and flow rate to vary the amount of flue gas recirculated from the convection section of the boiler to the radiant section and a second means responsive to changes in the outlet temperature of said process fluid to vary the amount of fuel feed to the combustion section of said boiler.  A boiler in combination with the improved control system and apparatus is particularly useful in controlling the coil outlet temperature of a hydrocarbon process fluid and offers distinct advantages in heating the feed slurry to a coal liquefaction process.

Abstract: TITLE:  AUTOMOTIVE FLOOR MAT HAVING RIGIDIFYING SHEET-FORM ELEMENT                 ABSTRACT OF THE DISCLOSURE        A floor mat for an automotive vehicle is provided having a relatively thin, flexible sheet-form main body and a rigidifying sheet-form element formed with or secured thereto in fixed relationship. The rigidifying element is fabricated from or formed by sheets of material that are effectively rigid in a thin sheet-form and thereby render the otherwise flexible main body essentially inflexible.  The materials selected to form the rigidifying elements preferably have a resilient characteristic, such as spring steel wire rod or inherent resilient rubber or plastic materials to enhance the mat's ability to maintain itself in a desired smooth, flat configuration on a vehicle's  floor.  The rigidifying element is of a configuration to rigidify the main body throughout most of its vehicle floor contacting area to resist displacement in all directions through the essential, rigidified portion of the mat encountering of any obstructions associated with the vehicle floor and the resilient characteristic of the rigidifying element accommodating excessive displacing forces and tending to return the main body of the mat to its original configuration.  The rigidifying elements may be rod-like elements or thin, flat sheets of material either integrally embedded in or formed with the sheet-form main body or they may be mechanically secured thereto.

Abstract: Abstract Bead ion exchange resin wastes are disposed of by a process which involves spray-drying a bead ion exchange resin waste in order to remove substantially all of the water present in such waste, including the water on the surface of the ion exchange resin beads and the water inside the ion exchange resin beads.  The resulting dried ion exchange resin beads can then be solidified in a suitable solid matrix-forming material, such as a polymer, which solidifies to contain the dried ion exchange resin beads in a solid monolith suitable for disposal by burial or other conventional means.

Abstract: ABSTRACT           A digital progess tone detector, for connection to a telephone line and a PABX, comprising circuitry for generating one or more reference tones having user definable frequencies and performing single frequency discrete Fourier transforms on one or more signals received from the telephone line at the defined frequencies, and providing an output signal to the PABX in response thereto.  The output signal provides an indication of whether or not a predetermined one or more progress tone frequencies have been detected in the received signals.  Because the generated reference tone frequencies are user definable, the present invention can be easily adapted for use in various foreign countries having different progress tone frequency requirements.  A preferred embodiment of the invention is implemented on a single microcomputer chip in conjunction with peripherals (such as codecs, crosspoint switches, etc.).  The progress tone detector is simple, small and inexpensive, thus conforming to the miniaturization and cost efficiency requirements of modern day PABX circuits.
