Title: Recovery of oil and gases from carbonaceous minerals, like oil sands and oil shales
Inventor: MUELLER WALTER A
IPC: E21B43/40
Filed: 1976-02-06
Granted: 1979-11-06
Abstract: ABSTRACT OF THE DISCLOSURE            A process for the recovery of oil and gases from carbon-aceous materials, while obtaining water enriched in deuterium oxide.          This process advantageously uses co-axial feed and extraction pipes to initiate the reaction between the carbonaceous minerals and the mixture of oxygen and steam.  Displacing the locus of feed and/or discharge pipes within the carbonaceous minerals permits the systematic extraction of the named products from the total mineral cross-section.  As addition to the conventional products, the recovery of deuterium oxide enriched water represents a source of heavy water of substantially reduced cost.  This production, of inexpensive deuterium oxide requires only the collection of all reacted water and steam from the reactio products.  The cost of the heavy water produced is inversely propor-tional to the content of deuterium oxide in the reacted water.

Abstract: POOL BALL SORTING APPARATUS            Abstract of the Disclosure Pool game apparatus having homogenous sperical balls of identical size including a cue ball of slightly higher specific gravity than the specific gravity of the object balls; a pool table internally carries a sorting device for the balls having a chute with a deflectable weighing plate pivotable about an axis parallel to the chute and having a trailing edge at an acute angle to the chute; the weighing plate is counterbalanced to remain stationary when an object ball passes over it, but to deflect on passage of the heavier cue ball so that the cue ball is diverted to the side of the path followed by the object balls by a stationary diverter plate adjacent the trailing edge; the chute floor is slated to one side of the chute axis and is pro-vided with a side support member so that a ball passing onto the weighing plate is supported by the floor and by the side support member.  The sorting action is effected not only by the diverter plate, but also by the change in slope of the weighing plate and the force of the side support member on the ball as the plate drops.

Abstract: HOT WATER SYSTEM            Abstract of the Disclosure:        This invention relates to a hot water system which utilizes heat from the refrigerant of a refrigeration system to produce hot water.  The utilized heat consists of the super-heat of the refrigerant vapor, the heat of condensation or latent heat, and part of the sensible heat of the liquid refrigerant.  The water passing through a water-cooled condensing unit, which is part of the refrigeration system, is heated to a selected temperature by removal of both the latent heat and superheat and part of the sensible heat from the refrigerant as it passes through the condenser unit.  The condensing unit has a water inlet and an outlet between which is connected a hot water storage tank.  As the water in the condensing unit is heated by absorption of latent and superheat and part of the sensible heat from the refrigerant passing therethrough, the heated water rises and flows by convection into the storage tank.  Eventually the storage tank may fill completely with water of a selected temperature.  A temperature responsive flow restriction device, or thermostat, is located between the water outlet of the condenser and the storage tank, which restricts the flow of water below a preselected temperature.  The heated water, being lighter than the balance of the water in the tank, will remain stratified at the top of the tank and may be drawn off as needed.          A condensing unit is especially designed with greater heat exchange surface than would normally be provided with the refrigeration system so that water at convection flow and at a higher temperature than normal can be used in the condensing unit and yet achieve the necessary absorption of heat from the refrigerant passing through the condensing unit as required for proper operation of the refrigeration system.  The condensing unit generally comprises a lower housing containing multiple layers of coils, the coils having multiple windings oriented generally horizontally to provide the heat exchange surface.  The housing has an inlet and outlet for the passage of water therethrough, said outlet being connected to a verticle riser tube in which is housed the thermostat.  Various refrigeration components are mounted on top of the condenser housing.

Abstract: ABSTRACT OF THE DISCLOSURE A push-pull mining system is provided herein comprising a pre-formed arrangement of personnel entry shafts, laterally extending service tunnels, flumes in the form of ditches extending substantially throughout each service tunnel, a holding tunnel at one side of each service tunnel and a chamber be-low the lowermost service tunnel at the end opposite to the holding tunnel for receiving a separation tank, a slurry mix tank, and an underground water res-ervoir.  A mobile mining unit, including a mining mechanism is initially disposed at each end and carriers therebetween, is of substantially the same length as the holding tunnel.  The mobile mining unit moves across the service tunnel to mine the opposing face and form a working tunnel which, when finished, is of the same length as the mobile unit.  A mobile water station is mounted in the ser-vice tunnel and is connected to the mid-carrier which conveys the water to the mining machine at the end which is effective.  A flexible slurry line extends from a slurry mix tank in each mining machine to the mid-carrier where it is connected to a fixed slurry line by a three-way valve.  The flexible slurry line extends along a working tunnel and is then diverted or bent into the ser-vice tunnel.  A reverse drive motor is positioned in the service tunnel and en-gages the fixed slurry line to move it in reverse directions as the mobile min-ing unit moves back and forth across the service tunnel to form additional working tunnels.  The fixed slurry line opens onto the flume when in a  retrac-ted position but when advanced to a predetermined extent enters the upper end of a downflow slurry tube.  The latter extends to a separation tank from which mineable material is passed to a main slurry mix tank.  It is moved outwardly to the ground surface through a tube.  Water for the slurry mix tanks in the mining unit is supplied from either a surface reservoir or an underground res-ervoir.  This mining system is more efficient and economical than previous sys-tems and offers safety features with regard to personnel entrapped underground.

Forces are applied to the furcations to move the free end portions toward each other to form a conductor-receiving slot therebetween of predetermined width characteristics, after which the connector is subjected to heat-treatment.  For some uses of these kinds of connectors, it may also be desirable to form the surfaces which define the conductor-receiving slot to a predetermined configuration and to coat or plate selected portions of the furcations.  In these instances selected surfaces of the furcations are configured and coated or plated preferably while the furcations are in the open position.         -i-
