Abstract: POWER LINE COMMUNICATION SYSTEM                 ABSTRACT OF THE DISCLOSURE           A distribution power line communication system wherein communication signals are transferred between a communication terminal at a substation and communication terminals at customer locations.  The communication signals are transferred between the terminals by using a two-conductor line, with one of the conductors effectively grounded and with the other of the conductors effectively isolated from ground.  The conductor which is isolated from ground provides a conduction path which travels along the primary distribution line to a distribution transformer location.  At this location, the conduction path is transferred lines between various distribution supports other transmission lines between various distribution transformer locations.  The messenger wire is suitably isolated from ground and the conduction path is transferred to separate secondary distribution lines adjacent to the messenger wire.  The final portion of the ground-isolated conduction path which directs signals to the communication terminals at the customer locations is provided by the secondary distribution lines and by the service lines extend-ing to the customer locations.

Abstract: ABSTRACT        A fluid regulating system has an electro-fluidic control loop in which a fluid control pressure indicative of the relationship between an existing fluid condition and a demand signal acts in opposition to a bias pressure on a control member forming part of a transducer, to provide an electrical output representative of the instantaneous position of the control member.  The electrical output is arranged to control a regulating device and so regulate the existing fluid condition in the sense to maintain the fluid control pressure substantially constant.  The fluid regulating system has advantageous application to metering of L.P.G. to the carburation system of an internal combustion engine.

Abstract: ABSTRACT OF THE DISCLOSURE            The electrodes of the steam generator are each formed as a horizontally extending disk to receive descending water jets from a distribution chamber above the electrode as well as with openings to direct water jets downwardly onto a collecting grid.  The current flows from the electrodes through the water jets to evaporate part of the water to steam.  Movable inter-ceptors are also mounted in the vessel to intercept the water jets for partial loads.  The invention results in a reduced overall height of the generator.  In a particularly useful embodiment,  the water distribution means are movable to adjust the number of water jets which impinge on the electrodes while the collecting means for intercepting the excess water are stationary. Each collecting means is also located out of vertical alignment with the respective electrode.  The distribution means are fixed to a rotatable pipe which serves to move the distribution means and through which water can be fed to the distribution means.  The latter embodiment results in a still further reduction of the overall height of the generator.

Abstract: ABSTRACT OF THE DISCLOSURE     In an aircraft ground proximity warning system that compares the rate of descent of an aircraft with its altitude above the terrain and in response thereto generates a warning signal when the aircraft's sink rate exceeds a pre-determined limit for a particular altitude, a first type of advisory voice warning is generated for combinations of lesser descent rates and greater alti-tudes and a second type of imperative voice warning is generated for greater sink rates at lower altitudes where the danger of the aircraft impact with the terrain is more significant.  In addition, the repetition rate of the advisory warning is increased as a function of increasing descent rate and the amplitude of the advisory warning can be increased as function of increasing descent rate in order to call attention to an increasing undesirable operating condition.

Abstract: ABSTRACT OF THE DISCLOSURE A process and apparatus are provided herein for thermally puri-fying waste water contaminated with high and low boiling point impurities, e.g., hydrocarbons, which effectively eliminates the use of secondary chemical agents.  The process comprises introducing the waste water into a stripping column so as to separate the waste water into waste vapor containing low boiling point impurities and waste water containing 2% of low boiling point impurities in the form of combustible hydrocarbons and high boiling point impurities.  The waste vapor containing the low boiling point impurities are supplied to a combustion chamber operating at a tem-perature in the range of from 900 to 1200°C., thereby producing substan-tially clean combustion gases.  The waste water is introduced into a forced-circulation evaporation system having first, second and third evaporation stages so as further to concentrate the waste water such that it leaves the evaporation stages as a concentrate of high boiling point impurities in a fluid condition, and waste vapors containing such low boiling point impurities in gaseous form together with steam.  The waste vapors from the first stage are fed directly to a combustion chamber where combustion  takes place at 900 to 1200°C., thereby substantially complete-ly oxidizing all of the organic impurities therein.  The waste vapors from the second and third stages are heated to 600°C., while, substan-tially simultaneously, pressurized air at 600°C. is fed to the waste vapors.  The waste vapor and air are introduced into oxidation chambers, respectively, where temperatures of 800°C. are obtained by means of spon-taneous combustion, thereby to bring about substantially complete combus-tion or oxidation of the organic, low boiling point impurities present. The heat for heating the waste vapors from the second and third stages is derived from the heat from the purified hot waste vapors of the respective oxidation chambers.  The resulting steam-gas flow substantially free of organic materials comprising purified waste vapors together with resulting combustion gases is introduced into a condensation chamber to produce a condensate of substantially pure water while a portion of the steam remains uncondensed.  The overall process is such that the concentrate leaving the third evaporation stage contains concentrated high boiling point impurities whereas the substantially pure water is obtained in the condensate from the second and first evaporation stages.  The entire evaporation and oxidation process takes place under pressure of 3 - 20 atmospheres gauge.  The stripping column is operated with the uncondensed remainder of the steam and the oxidizing gas from the evaporation system. The water vapor departing from the waste vapor oxidation after its conden-sation supplies substantially pure water practically free of organic or inorganic impurities.

Abstract: IMPROVED BREATHER VENT FOR VAPOR VENT VALVE          Abstract of the Disclosure A breather vent mountable on the vent pipe outlet from an underground storage tank at a gasoline service station site.          A vent housing includes a body section adapted for placement on the vent pipe and which cooperates with a superposed cap section to accommodate a vapor floatable valve disc supported internally thereof.  Vapors from the tank can normally discharge in a pri-mary flow path past the valve disc from where it is diverted up-wardly by an annular diverging deflector  to atmosphere.  Dis-placed apertures having comparatively increased protection against freezeup form an alternative outlet for a secondary flow path diverted downwardly from a location downstream of the valve disc.  The latter being better protected against freezing rain, etc. enables continued vent discharge to atmosphere in the event the primary flow path becomes ice blocked.   1a
