Abstract: Abstract of the Disclosure An apparatus for downhole steam generation employing dual-stage preheaters for liquid fuel and for the water.  A first heat exchange jacket for the fuel surrounds the fuel/oxidant mixing section of the combustor assembly downstream of the fuel nozzle and contacts the top of the combustor unit of the combustor assembly, thereby receiving heat directly from the combustion of the fuel/oxidant.  A second stage heat exchange jacket surrounds an upper portion of the oxidant supply line adjacent the fuel nozzle receiving further heat from the compression heat which results from pressurization of the oxidant.  The combustor unit includes an inner combustor sleeve whose inner wall defines the combustion zone.  The inner combustor sleeve is surrounded by two concentric water channels, one defined by the space between the inner combustor sleeve and an intermediate sleeve, and the second defined by the space between the intermediate sleeve and an outer cylindrical housing.  The channels are connected by an annular passage-adjacent the top of the combustor assembly and the countercurrent nature of the water flow provides efficient cooling of the inner combustor sleeve.  An annular water ejector with a plurality of nozzles is provided to direct water downwardly into the combustor unit at the boundary of the combustion zone and along the lower section of the intermediate sleeve.

Abstract: MICROWAVE TREATING MECHANISM                 ABSTRACT OF THE DISCLOSURE      A housing rotatably supports a hollow drum on sub-stantially a horizontal axis whereby articles to be treated tumble around the interior of the drum when the latter is rotated.  A microwave power mechanism, such as a magnetron, is provided in a door for the housing and has an output portion thereof directed into the drum for heating and dry-ing articles tumbling in the drum.  An output portion of the microwave power mechanism has a dielectric dome-like shield mounted over it for deflecting tumbling articles away from such output.  A forced air system is provided for ventilat-ing the interior of the drum, and such system includes a passageway extending adjacent to the power mechanism so that such ventilating air also cools the power means.  The present mechanism is associated with an electrical circuit having door interlocks, door panel interlocks, and other interlocks, as well as a magnetically operated door inter-lock that is substantially foolproof so that power from the microwave power mechanism is positively deenergized when the door is open.  Circuitry is provided for the microwave power mechanism to protect it from excess average and peak reflected power.  The circuitry also includes a humidity sensor to prevent excessive drying.

Abstract: ABSTRACT            Summary In order to increase the effectiveness of familiar compressed air blasting techniques, under the terms of this invention it is proposed that the outlet nozzle that is configured in an already familiar manner as the laval nozzle is provided with a funnel-shaped nozzle attachment that includes an extended paraboloid inner chamber.  During operation underwater, even at great depths, it is futher proposed that between the compressed gas source and the line that leads to the outlet nozzle an additional controllable secondary connection for the compressed gas be provided, this bypassing the source of the working agent.  The compressed gas that is passed through the secondary connection can, with suitable pressure regulation, ensure that no water penetrates into the jet system that is located beneath the surface.   Thus the area between the outlet nozzle and the surface that is to be processed can be kept free of water and the working agent can impact with considerably greater energy onto the surface that is to be treated.

Abstract: ABSTRACT      Curable compositions comprising an epoxide resin and an aliphatic amine curing agent are rendered less viscous, and their rate of cure is accelerated, by the addition of an ester of the formula                         I   wherein n represents an integer of from 1 to 6, R represents the residue of a mono- or polyhydric alcohol or phenol after removal of n  hydroxy groups, and R1, R2, and R3, which may be the same or different, each represents a hydrogen or halogen atom or an alkyl group, or one or two of R1, R2 and R3 may alternatively represent an acyloxy group.  Typical such esters of formula I include diphenyl carbonate, bis(phenoxycarbonyloxy) polybutadiene, and tris(phenoxycarbonyloxy) poly(oxypropylene).    The compositions may be cured at room temperature and are particularly suitable for use as coatings and castings.

Abstract: Abstract of the Discusser A bellows capsule for use in applications where the pressure on the outside of the bellows capsule is substantially higher than that on the inside is formed with spacer rings positioned between the diaphragms forming adjacent bellows convolutions at the inner diameter of the bellows.  The total thickness of each diaphragm pair and the intervening ring is greater than the diameter of the bead at the outer diameter or rim of each bellows convolution.  When the bellows is urged to its fully compressed position, its diaphragms are able to nest so that the wall portions having a large pressure differential across them are supported by an adjacent diaphragm and a load bearing column is provided at the inner diameter of the bellows thereby minimizing diaphragm fatigue caused by repetitive high pressure stresses on the bellows when the bellows is cycled to its fully compressed position.

The fibers are oriented in generally perpendicular directions in each board layer.  The board layers are joined by means of a bridge formed from binders, which are added to at least one of the board layers.  According to the production process, prefabricated base boards are moved in contiguous manner on a conveyor belt.  The fibers of the base boards are at right angles to the conveying direction of the board.  A slurry or paste-like moist mass containing fibers is applied thereto with the belt moving and this forms the next board layer.  The fibers of the moist mass are preferably aligned parallel to the belt conveying direction.  The boards are then dried.  The strength, as well as the dimensional and shape stability of the boards are considerably improved.

Abstract: ABSTRACT OF THE DISCLOSURE     A mechanism for a data processor that is adapted to receive strings of object code, form them into higher level tasks and to determine sequences of such tasks which are logically independent so that they may be separately and concurrently executed by a plurality of processing elements.  The mechanism makes all memory accesses required by the various tasks and stores those tasks along with corresponding pointers or references to local memory in which the various data items have now been stored.  The mechanism employs a symbol translation table in which the tasks are stored in forms of queues along with symbols representing the various references or pointers to local memory.  In this manner, various data items can be assigned different symbols or symbolic names for use with different tasks thus further limiting dependency between various tasks and controlling data changes.

Abstract: ABSTRACT             A method and apparatus is disclosed for automatic control of battery maintenance including fast recharge and equalizing of the voltages on individual cells of the battery.  The charging current through a resistance in series with the battery is monitored, and in response, a control circuit energizes a relay which controls the output voltage of a power supply used to charge the battery and drive a load.  The control circuit includes a clock, connected to a recharge counter, which effects the recharge process for a predetermined period of time.  The recharge counter is connected to the relay which regulates the output voltage of the power supply.  The control circuit also includes a battery current sensor, which monitors the charging current of the battery, and a second counter, which provides an enabling signal to the relay for initiating a longer cycle which equalizes the charges on individual cells of the battery if the battery has been recharged from a severely discharge state.
