Abstract: A system and method for controlling the sealing efficiency and recycle rate in a fluidized bed reactor in which air is introduced into two chambers found in a sealing vessel for receiving the separated solids from the separator. The air is introduced into two chambers in the sealing vessel in a direction opposite to that of the flow of the separated solids through the vessel. One of the chambers is located below the separator dipleg and in alignment therewith and the other chamber surrounds the first chambers. The air flow through each path can be separately adjusted as necessary.

Abstract: A fluidized bed steam generation system and method in which an external heat exchanger is located adjacent a furnace section. A mixture of flue gases and entrained particulate materials from a fluidized bed in the furnace section are separated and the flue gases are passed to a heat recovery section and the separated particulate material back to the fluidized bed in the furnace section. Particulate material from the fluidized bed in the furnace section is circulated through the external heat exchanger to add heat to water, steam or a steam/water mixture before the material is passed back to the furnace section. Water is passed through the furnace section, the heat recovery section, and the external heat exchanger to convert the water to steam.

Insulation means extend around the bundles of wire strands. A pair of cables configured in the above manner are provided to carry the positive and negative signals between a power source and a load.

Abstract: A connector for connecting an electrical signal transmitting cable to a corresponding jack and including a cylindrical base member having an end for receiving the cable. A sleeve forms an extension of the other end of the base member and is adapted to engage over a corresponding flange of the jack. The sleeve is formed by a plurality of angled segments. A pin projects from the second end and is adapted to extend in a corresponding socket of the jack.

Abstract: A conductor assembly formed by a pair of cables each formed by two conductors in a side-by-side relationship. One conductor of each cable includes at least one wire and the other conductor of each cable is formed by a plurality of bundles of wires. The diameters of a portion of the wires are of a different gauge. The conductors are surrounded by insulation which is configured to permit the assembly to be installed around a corner and to permit one cable to be bent back upon the other. The two conductors of each cable can be mechanically connected together so that they together carry the positive or negative portion of the signal or can be separately connected so that they each carry different frequency components of the signal.

Abstract: A fluidized bed stream generating system in which a cyclone separator is disposed between the furnace section and heat recovery area of a steam generating system. The walls of the cyclone separator are provided with tubes which receive fluid from the steam drum. The fluid is passed through the walls of the separator to cool same before being passed to the heat recovery area.

Abstract: A reactor in which a furnace section and a heat recovery section are formed in a vessel. A bed of solid particulate material including fuel is supported in furnace section and air is introduced into the bed at a velocity sufficient to fluidize same and support the combustion or gasification of the fuel. A mixture of air, the gaseous products of combustion, and the particulate material entrained by the air and the gaseous products of combustion are saturated with the particulate material and directed to the heat recovery section, and a plurality of channel beams are disposed in the heat recovery section for separating the particulate material from the mixture. A trough extends between the furnace section and the heat recovery section for receiving the separated particulate material from the channel beams, and the trough is connected to the furnace section for returning the separated particulate material back to the bed.

Abstract: A vessel for separating entrained particles from a gas in which a vertically extending tubular portion extends through a portion of a housing for providing an outlet for the gas after separation from the particles. The tubular portion includes a tube formed into a spiral coil, and a continuous fin extends from the tube for the entire length of the tube. The fin is welded to adjacent sections of the tube to render the coil airtight. A layer of insulation material extends to both sides of the coil.

Abstract: An apparatus and method for raising and supporting the foundation or slab of a building, in which a lifting arm assembly engages the lower surface of the foundation or slab and is secured thereto. A piling assembly is disposed in a support sleeve adjacent the lifting assembly and is engaged by a clamping assembly. A hydraulic ram is connected between the clamping assembly and the lifting arm assembly in the expanded position of the ram so that when the ram is retracted, the piling is driven into the ground until it encounters a predetermined resistance. A drive plate is placed in operative relation to the piling assembly and over a pair of rods attached to the lifting arm assembly. The ram is further actuated after the predetermined resistance is encountered to raise the lifting arm assembly, the rods, and the foundation or slab a predetermined distance relative to the drive plate, after which the rods are secured to the piling assembly.

Abstract: A cable assembly in which a pair of cables are provided to carry the positive and negative signals between a power source and a load. Each cable consists of a conductor wrapped around a dielectric core, and a plurality of bundles of wire strands are twisted around the wrapped dielectric core. The wire strands forming each bundle are twisted in a first direction and the bundles are twisted around the solid conductor in a direction opposite the first direction. Insulation extends around the bundles of wire strands.

Abstract: A cyclone separator in which an outer cylinder is formed by a plurality of vertically-extending, spaced, parallel tubes and extends around an inner pipe in a coaxial relationship therewith to define an annular chamber. A portion of the tubes forming the outer cylinder are bent out of the plane of the cylinder to form an inlet opening in a tangential relationship to the annular chamber for receiving gases containing solid particles and directing same through the annular chamber for separating the solid particles from the gas by centrifugal forces. The tubes are bent radially inwardly towards the inner pipe and radially outwardly to form a roof for the annular chamber.

Abstract: An absorber/solution pump for pumping strong concentration liquor up a pressure gradient to a vapor generator in a heat-pump system, said pump comprising a pump body defining a first vertically disposed cylinder and housing a first piston which reciprocates within said cylinder, dividing it into an upper pumping chamber and a lower working chamber, a header tank for the system strong concentration solution integral with said pump body and surmounting said pumping chamber, said header tank and said pump body being interconnected via a one-way valve which allows the strong-concentration solution to be drawn by suction and gravity into the pumping chamber, a second piston within a second cylinder which is connected to the first piston so as to reciprocate with it, said second cylinder opening at the bottom into the pumping chamber and opening at the top into the base of the header tank, and a third piston acting vertically in a third cylinder which is closed at the bottom from the atmosphere but is selectively c

Abstract: A gas equalizer device for use in conjunction with a reciprocatory pump located downhole in a wellbore. The device of the present invention avoids a condition commonly known in the pumpjack art as "fluid pounding", which is brought about when compressible gases accumulate in the working chamber of the downhole pump. The gas equalizer device of the invention includes a pushrod having a marginal end reciprocatingly enclosed in a slidable manner within a housing which is mounted to the usual traveling valve cage of the downhole pump. The pushrod is alternately moved from an extended into a retracted position each upstroke and downstroke of the pump. The free terminal end of the pushrod is arranged to engage the ball check valve of the traveling valve assembly as the pump commences the downstroke. This unseats the ball, thereby allowing any accumulated gases to escape from the variable pump chamber.
