netted after a pressure gasification. The wasteheat tank has a cooled feed device or tubular-fintubular construction which includes an ash container. The waste-heat tank also has a gas/liquid heat exchanger which includes equally long tubular elements which serve as heat transfer surfaces and are integrated into tubular or planar wall units. Each element of the tubular elements is formed of a tube having an axis which is located extending generally parallel to the container axis of the waste-heat tank. Each element itself is guided in a winding manner. Each tube opens via a feed tube into the finger-like end portion of the feed device. The finger-like end portion is coated with refractory material. Each tube is arranged in an individual tubular or channellike chamber about a polygonal, preferably hexagonal, tubular or channel-like inner space arrangement.
4564174 DEVICE FOR THE RECOVERY OF MERCURY Ake Sikander, Ake Biorkman, Gunther Jonsson, Karlskrona, Sweden assigned to Lumalampan Aktiebolag This process enables the recovery of mercury from waste containing plastic material, e.g. batteries. The waste is slowly heated while an inert gas is being introduced in a vacuum for fractionating extraction of the products of the decomposition of the plastic. The waste gases must pass through an afterburner chamber incorporating a specially shaped burner where the plastic vapors are fully cornbusted. The waste gases are conducted from the afterburner chamber through a cooling trap and then through a cold trap in which the mercury is condensed and can be drained off. The final stage of the process is carried out in a pulsating vacuum by the inert gas. The device in which the process takes place consists of a heated heat isolated treatment chamber (2), an afterburner chamber (6), a cooling trap (7), a cold trap (18) and a vacuum pump (23, 24) connected with pipelines (5, 12, 21). The system also includes a control unit (14) for regulating the operation of the vacuum pump (23, 24) and the settings of a shut-off valve (16) and a regulation valve (15) for the inert gas. The plastic vapors are cornbusted in the afterburner chamber (6) by being heated in a flame basket produced with the aid of a concave flame cup (36) made of heat-resistant material.
4564445 SELF-CONTAINED SEWAGE WASTE DISPOSAL SYSTEM Clifton F Briner, William R Bocchini, Brian Wilcockson assigned to American Standard Inc A self-contained sewage waste disposal system is provided including a housing structure and a toilet bowl adapted to receive human waste and fluid for diluting the waste, transporting the waste and rinsing the bowl is provided in the housing structure. A removable filter cassette is placed in the housing structure in communication with the toilet bowl. The bowl is adapted to be flushed to dump the contents into the filter cassette and to be subsequently refilled. The coarse and fine particles of solid waste material are separated from the fluid received from the bowl by filter material in the cassette. The solid material is stored in the cassette in a compact manner for subsequent disposal upon removal of the cassette from the housing. A pump and interconnected conduits in the housing transport fluid from the interior of the system to fill the bowl after a flush, to transport filtered fluid from the filter cassette to a position for recirculation, and to transport excess fluid from the interior of the housing to the exterior thereof. The recirculated fluid is sanitized and deodorized in the housing. Controls are provided to pass the fluid through the system to facilitate the collection and disposal of sewage waste within the system in a predetermined sequence.

subsequently refilled. Filters in the cassette separate the coarse and fine particles of solid material from the fluid received from the bowl. The solid material is stored in the cassette in a compact manner for subsequent disposal upon removal of the cassette. Fine filtering and decoloring is accomplished by a carbon canister. A reservoir is provided for storage of fluid after removal of solid material therefrom in the cassette. Pumps and interconnected conduits are in the housing to transport fluid from the interior of the system to fill the bowl after a flush and to transport filtered fluid from the filter cassette to a position for recirculation and to the reservoir. Controls are provided to pass the fluid through the system to facilitate the collection and disposal of sewage waste within the system in a predetermined sequence.

4564458 METHOD AND APPARATUS FOR DISPOSAL OF A BROAD SPECTRUM OF WASTE FEATURING OXIDATION OF WASTE James C Burleson In the preferred and illustrated embodiment, a deep well is utilized to form a reaction chamber for combustible waste in water. A stream of water born combustible waste is delivered into a deep well, sufficiently deep to obtain a pressure and temperature in a bottom located reaction chamber at which the water becomes supercritical, there being a pipe for delivering oxygen under pressure for cornbusting oxygen dissolved in the supercritical water with the waste materials. The reaction is exothermic to sustain itself. It is started preferably by electric current flow to initially raise the temperature in the reaction chamber. The preferred structure is a cased abandoned well having a surrounding cement bond to the formation thereby retarding heat lose into the formation, the bottom located reaction chamber sustaining supercritical conditions.

4564508 PROCESS FOR THE RECOVERY OF SODIUM CARBONATE FROM SALT MIXTURES Michael J Fair-weather, Michael Rockandel, Abraham Sadan, Godefridus M Swinkels, Rossland, Canada assigned to Cominco Ltd Mined salt mixtures comprising sodiumcarbonate, -bicarbonate, -chloride, -sulfate, and -double salts, such as trona and burkeite, are leached with a bicarbonate-saturated solution and added carbon dioxide to selectively dissolve the sodium chloride, sodium sulfate and burkeite and to precipitate additional trona, leaving a leach residue consisting essentially of trona. The trona is calcined and dissolved, and the carbonate solution is purified, crystallized and dehydrated in a non-convective solar pond yielding high purity sodium carbonate monohydrate
