Abstract: A reactor in which a plurality of vertical panels are disposed in a vessel and are constructed and arranged so as to form three combustion cells. Three of the panels each form a common wall between adjacent cells, and each cell is heated by a fluidized bed.

Abstract: A process for preparing a gas stream containing sulfur dioxide and water for reaction with coal to convert the sulfur dioxide to gaseous elemental sulfur. Water is initially removed from the gas stream to increase the percentage of sulfur dioxide in the stream after which the gas stream is passed through the flame of a burner to add combustion gases to the gas stream. Steam is then mixed with the gas stream to increase the percentage of water in the gas stream before it is reacted with the coal.

Abstract: A fluidized bed reactor system for introducing heat energy into or removing heat energy from fluidized reactants undergoing reaction includes, in a first embodiment, a fluidized bed reactor for fluidizing a particulate material in a fluidizing medium and a heat generator for supplying heat energy to the fluidized bed. A plurality of heat pipes interconnect the heat generator and the fluidized bed reactor with the evaporator portions of the heat pipes extending into the heat generator and the condenser portions thereof extending into the fluidized bed. Thermal energy from the heat generator is absorbed by the evaporator portions of the heat pipes and conveyed through the heat pipes to the condenser portions where the thermal energy is transferred to the fluidized bed.

Abstract: The invention relates to air heaters and provides a means by which the operation of heat exchangers therein can be sustained at an optimum efficiency. The invention proposes the incorporation of a preheater (16) for incoming unheated air which can be selectively thermally coupled to heated air in an outlet duct (12) from the heat exchanger (4). During normal operation the heated air bypasses the thermal coupling, but when the temperature of the incoming unheated air is particularly low, the coupling is made and the incoming air thereby preheated to ensure efficient operation of the heat exchanger.

Abstract: A vapor generating system including an upright furnace section formed by a plurality of tubes, a portion of which extends vertically and a portion of which extends at an angle with respect to a horizontal plane for passing fluid through the length of the furnace section to convert a portion of the fluid to vapor or to heat the fluid. Each angularly extending tube portion bifurcates into two vertical tube portions and a bifurcate fixture is provided at the junction between the respective tube portions. Each of the bifurcates connecting the angularly extending tube portions to their respective vertical tube portions in the upper portion of the furnace section includes a splitter plate to distribute the fluid in the angular tube portion equally to two vertical tube portions.

Abstract: A combustion system and method for a coal-fired furnace in which a separator-nozzle assembly divides a coal-air mixture into a first stream containing most of the coal and a second stream containing a much smaller quantity of coal. Another nozzle is provided which receives another mixture of coal and air and discharges same in a combustion supporting relation to said streams. At start up and low loads, the separator-nozzle assembly discharges a majority of the coal and air in a combustion supporting relationship and the other nozzle discharges a relatively low quantity of coal and air. At high load conditions, the other nozzle discharges a majority of the coal and air while the coal and air discharging from the separator-nozzle assembly is kept at relatively low values. A splitter is provided for receiving a coal-air mixture from a mill and splitting it into two separate mixtures.

Abstract: An injection assembly for an injection molding machine in which an auger is disposed in a bore formed in the molding machine and defines therewith an annular passage for receiving the material to be injected. A valve assembly is operatively connected to the auger and includes internal passages communicating with the annular passage and adapted to communicate with the mold. A sealing ring extends around the valve with the outer diameter of the sealing ring being in a sealing relation to the bore downstream of the annular passage. The inner diameter of the ring is slightly greater than the outer diameter of the valve to permit rotation of the valve relative to the sealing ring. As a result, upon rotation of the auger and the valve, the material is advanced along the annular passage and the internal passages while the sealing ring remains stationary and provides the sealing function.

Abstract: A crimped banana-type electrical connector includes an axially extending male pin having a conductive contact portion and a connector post extending axially from one end of the pin. The stranded or solid core of a wire or wires is positioned along the exposed post and a crimping ferrule placed over the wire and the post. The crimping ferrule is forced radially inward to crimp the wire to the post and, thereafter, an insulating sleeve is placed over the crimped connection to provide a compact and permanent mechanical and electrical connection between the wire and the banana-type pin.

Abstract: A method for drawing a plat from a metes and bounds property description includes the steps of providing a first page presenting a compass rose and a grid pattern. A plurality of lines are then created on the first page, each beginning at a center point on the compass rose and extending in a direction of a respective call of the metes and bounds measurements. Each of the plurality of lines are then numbered to correspond to the order of the respective calls. A second page is also provided having a grid pattern thereon which is aligned with the grid pattern of the first page. A first line corresponding to a first call of the metes and bounds description is then traced from the first page onto the second page, and the line is scaled an amount corresponding to a magnitude of the first call.

Abstract: An apparatus and method for mixing and distributing solid material in which the material is continuously introduced into a vessel and a pressurized gas is introduced into the lower portion of the vessel at a velocity sufficient to pass upwardly through the material in the vessel to promote mixing of the material. A plurality of outlets are disposed in an angularly spaced relation along the vessel for permitting the material to continuously discharge to a plurality of selected locations. The excess gas in the vessel is removed, cleaned and introduced back into the vessel.

Abstract: A fluid injection system for an internal combustion engine, including both spark-ignition and compression-ignition engines, includes a nozzle for injecting a finely divided spray of fluid, such as water, a water solution, or other combustion enhancing fluid, into the intake air of the engine in response to a flow of atomizing air. The nozzle is connected to a fluid supply and to the outlet an air injection pump that is connected to an electric drive motor. The drive motor is controlled by an electronic control circuit to provide the atomizing air to the nozzle in response to the fuel flow to the engine and in response to one or more engine parameters including parameters provided by a temperature sensor, a throttle position sensor, and/or a detonation sensor.

Abstract: A longitudinally adjustable ski pole is provided with two tube sections arranged telescopically movable into each other and are provided with a latch and several catches. When shortening the ski pole a spring is tensioned. An extending of the ski pole in longitudinal direction is caused by the tensioned spring. The switching element is arranged, for instance, at the rear side of the hand grip of the ski pole. The latch is supported at the outer of the tubes and the catches are located at the inner of the two tubes. The catches are formed as a through hole through the tube and comprise a supporting shoulder provided with a supporting face. The latch is arranged at a tilting lever which is spring biased and operationally connected to a switching member. The entire mechanism for the longitudinal adjustment of the ski pole is arranged in the grip section of the ski pole. This grip section can quite easily be mounted to the common ski pole tubes.

Abstract: An adjustable classifier for the separation of fluid-suspended solid particles in industrial processes and by which the relative proportion of acceptably fine and unacceptably coarse solid particles may be regulated. Adjustability is achieved in an otherwise static classifier structure in which a fluid stream of multi-sized particles is passed through a curved path, by the provision of interleaved fingers movable from a retracted inactive position against an outer boundary surface defining the curved path to an extended position into the stream to re-entrain all particles moved against the outer boundary surface back into the fluid stream. Fine particles so re-entrained will pass from the classifier and relatively coarse particles will be rejected by centrifugal action. The invention also contemplates an adjustable plate member by which the velocity of the fluid stream may be regulated independently of the aforementioned fingers.

Abstract: An improved ski pole having an adjustable length is provided with two telescopically movable tube sections. The tube sections are inserted into each other and are movable relative to each other and are provided with a latch and a plurality of catches. When shortening the length of the ski pole, a spring is tensioned. The increasing of the length of the ski pole is caused by the tensioned spring. The switch is arranged at the reverse side of the grip of the ski pole. The latch is arranged fixedly at the inner tube section and the catches are arranged at a pivotable cylinder which can be elevated and lowered as well as rotated. The catches are defined by horizontally extending sections of at least one Z-shaped groove. The pivoting cylinder is connected at a off-center pivot point to the switching or operating, respectively, member. The entire mechanism for the longitudinal adjustment of the ski pole is arranged in the gripping section of the ski pole.
