4977094 Process for monitoring the quality of water
New Patent
4976209 FURNACES FOR INCINERATING WASTE MATERIAL Peter R Piggin, Gaulby, United Kingdom assigned to Erithglen Limited A vertical-chamber for waste disposal and heating purposes has an upright combustion chamber with an inlet for waste material, a grating at a lower chamber end and an adjustable burner controlled by a temperature sensor so that the burner operation can be adapted to allow for the calorific value or requirement of the material to be incinerated. A trap door is situated at the lower end for ash removal and is arranged by air passages to permit air to pass upward past the door for combustion and to open periodically for removing ash. The grating may be water cooled and step down towards the trap door to permit ash to be blown off onto the door before the door is opened.
4976853 CONTROL VALVE MEANS FOR USE IN A FILTRATION APPARATUS FOR TREATING WASTE PRODUCT Chung Y Lee, Dongiak Ku, Seoul, Republic Of Korea An improved control valve for use in a filtration apparatus for treating waste product which comprises a tapered rotary cylinder, a rotary filtration cylinder disposed around the tapered rotary cylinder, a fixed steam injection pipe disposed above the rotary filtration cylinder, and a plurality of control valve members whereby the waste product which is conveyed inside the rotary filtration cylinder and is heated, and which collects in the holes of the rotary filtration cylinder is cleaned away by the spraying of the surface of the rotary filtration cylinder with hot steam through nozzles of a fixed injection pipe under the control of the pressure in a treatment zone between the tapered rotary cylinder and the rotary filtration cylinder.

XV
A process for treating wastewater containing insoluble solid waste material and soluble solid waste material including the following series of steps: (1) controlling the oxygen content of the wastewater to a level at which growth of anaerobic bacteria is substantially eliminated, (2) separating the insoluble solid waste material from the wastewater, (3) treating the soluble solid material in the wastewater with a predetermined amount of aerobic bacteria, and (4) reducing the amount of aerobic bacteria in the wastewater. The insoluble solid waste material separated from the wastewater can be burned to produce electrical energy. Apparatus for carrying out the process are also disclosed.
4976876 POINT-OF-USE MEMBRANE FILTRATION SYSTEM Charles Diman, David Marcus, Philip Mitchell, Baruch Sachs assigned to The Kendall Company A point-of-use membrane filtration system and method for water or other liquids including an automatic control system for purge, rinse-up, sanitization, or combinations thereof. The system may be used for microfiltration, ultrafiltration or hyperfiltration (reverse osmosis) depending on the membrane pore size of the filtration cartridge employed in the system. A reject valve at the bottom of the filter cartridge is automatically opened when filtered product is drawn, thus to direct some water and any waste to drain. The control system is programmed to accomplish purge, rinse-up and sanitization procedures at predetermined intervals with predetermined combinations of procedures.
4977094 PROCESS FOR MONITORING THE QUALITY OF WATER Arthur Goldstein, Edgardo J Parsi assigned to Ionics Incorporated A process is disclosed for monitoring the quality of water, said process comprising a first heated zone, means for introducing at least a portion of said water into said first heated zone, means for gently evaporating at least part of the water in the first heated zone and passing the vapor into and through a second heated zone, means for maintaining the temperature of said second heated zone in the range of from about 450

degrees to about 1000 degrees C., means for collecting and condensing vapor from said second heated zone to condensed liquid water and means for measuring the electrical impedance of at least a portion of said condensed liquid water.
cled gas-enriched fraction from the vortex separator device (13). This is done by means of a venturi system (19) controlling a servo-valve (25) which in turn controls the control valve (21). By using a magnified image of the gas content, the system is made more sensitive and more reliable.

METHOD AND APPARATUS FOR MONITORING THE CONDITION OF CHARGE OF A BATTERY CONNECTED TO AN APPLIANCE AND INCLUDING COUNTERS COUNTED WITH RESPECT TO THE TIME AND DRAIN OF THE BATTERY Werne Arnold, Peter Grundl, Nuremberg, Federal Republic Of Germany assigned to Diehl GmbH & Co A method and apparatus for monitoring the state or condition of charge of a battery which supplies a plurality of electrical consumption devices in an electronic circuit. A consumption device is operatively connected to a series of counters so that the count condition charges in response to a pulsing rhythmic cycle by one of a plurality of numerical values toward a final count condition, in which the numerical values are specific in relation to the power consumptions of a plurality of electrical consumption devices, and that a signal is generated upon the reaching of a final count condition.
4978374 LIQUID HYDROCARBON DELIVERY MEANS INCLUDING MEANS FOR MONITORING GAS CONTENT Sylvain Janssen, Jacques Fournier, Neuilly, France assigned to Schlumberger Industries When a hydrocarbon liquid is pumped (11) for retail delivery, it is degassed by means of a vortex device (13). A control valve (21) shuts off delivery if the'gas content in the degassed liquid being delivered via a main duct (16) is too high. Unlike prior systems which sense gas content only in the liquid being delivered, the present invention senses the greater gas content in the recy-

A corrosion product monitoring system and method are described using a recirculation loop including a sample line, a particulate collection vessel, a recirculating pump, a microporous membrane cross-flow filter, and valves to control the flow rate and pressure of a fluid sample taken from the secondary fluid system of a nuclear power plant. The liquid sample is processed at a constant flow rate and temperature. When a relatively short time has elapsed in a trial sample run to stabilize conditions in the sample line, an actual sample run is started by feeding sample into the loop. Non-soluble, particulate concentration increases in the filter and particulate collection vessel as the run progresses. The permeate of soluble contaminants is passed through an ion exchange column to concentrate soluble ions in the sample. The filter is backwashed on a timed cycle by filtered water pressurized by a pump, or gas pressure, by realigning the system valves. A total sample volume is determined by measuring the amount of filtered, deionized water discharged during the actual sample run, based on total weight, total flow or time at a constant discharge rate. A concentration factor can be determined from the total sample volume divided by the initial system volume. A sampleof the non-soluble particulates can also be drawn from the particulate collection vessel for analysis, The related method includes the steps of: taking a sample from a fluid system; introducing the sample to a recirculation loop having an initial system volume; separating nonsoluble particulates from soluble contaminants; suspending the solid particulates; collecting the solid particulates in a particulate collection vessel; and determining a corrosion concentration factor from the total sample volume divided by the initial system volume.
