Title: Predistortion compensated linear amplifier
Inventor: MYER ROBERT E
IPC: H03F1/32
Filed: 1989-08-22
Granted: 1992-02-11
Abstract: A PREDISTORTION COMPENSATED LINEAR AMPLIFIER Abstract A distortion compensation circuit for power amplifier producing a prescribed distortion component receives an input signal having at least one carrier therein in a prescribed frequency range. The input signal is applied to a first circuit path having an amplifier that produces an amplified signal with the prescribed distortion component and to a second circuit path that delays the input signal without distortion. The output signals of the first and second circuit paths are combined in a first combiner to form a signal representative of the prescribed distortion component. A second combiner forms a signal having an amplified input signal component and inverted phase prescribed distortion component responsive to the output of the first combiner and the output the first circuit path. To eliminate signals other than the distortion component from the first combiner, the prescribed frequency range is scanned to detect a carrier signal and the amplitude and phase of the signal in the second circuit path is modified to remove the detected carrier from the output of the first combiner. Remaining distortion in the power amplifier output is removed byscanning the prescribed frequency range to detect an intermodulation product signal and modifying the amplitude and phase of the first combiner output to minimize the detected intermodulation product signal.

Abstract: MEDICAL IMAGING APPARATUS          Inventor(s):            Abstract of the Invention An x-ray source having two levels of radiation is used to radiate a target and the x-ray image is displayed on an image intensifier. A video camera photographs the x-ray image and displays it on a monitor screen directly when the source is in a first low level mode of operation.  When a selected image is identified, a control generator is activated which changes the mode of operation of the x-ray source to a higher level while at the same time inactivating the video camera for a period of time sufficient to allow the monitor screen to be cleared.  The camera is then activated and at least one video frame of the high intensity x-ray image is stored in memory.  The control generator also serves to synchronize the various activities of the components.

Abstract: An excavating tooth for use in connection with an earth drilling auger includes a main body portion terminating in a working end and a shank extending upwardly from the main body portion.  A plurality of tungsten carbide inserts are embedded in the working end of the tooth and project outwardly therefrom.  During drilling operations, the carbide inserts engage the earth and chisel away rock and other material which is subsequently conveyed to the surface by the fight structure of the auger.  The inserts are inclined forwardly with respect to the plane of the shank to enable the inserts to withstand greater loads than before.  In the preferred embodiment, the insert has a generally cylindrical proximal end embedded in the working end of the auger tooth and a distal end including forward and rearward inclined surfaces terminating in a transverse cutting edge.

Abstract: COMPACT TWIN PISTON PUMP            Abstract of the Disclosure A  compact,  relatively  low  Cost twin piston pump (20) especially adapted for the pump ing of foods (e.g.  juices, puddings or particu-lates such as stews and chilies) is provided which includes quick detach yoke and clevis assemblies (108,  124, 110, 126) connecting the reciprocable pistons (100, 102) with their associated hydraulic cylinders (116, 118), thereby permitting quick cleanup of the machine (20).   A jacking screw plate (136) is used for forward mounting of the piston and cylinder assemblies (84, 86, 116, 118) coupled with the sleeves (42, 44) and associated pistons (100, 102).  This permits precise adjust-ment of the working components of the machine, while eliminating expensive bearings and heavy duty  framing members.   The pump (20) is also provided with a slide plate-type valve (38, 184) for controlling output of product from the pump (20).   In one valve embodiment (184) a two-part metallic slide plate assembly (192, 200) is sand-wiched between a pair of apertured nylon plates (186).  One of the slide plate parts (200) is of lesser thickness than the primary part (192), so as to permit limited fore-and-aft movement of the part (200) for sealing purposes.  A unique hy-draulic system employing a master pressure reduc-ing valve (222) and a slaved pressure reducing valve (224) is employed for creating a pressure differential across the part (200) in order to bias the same for sealing purposes.

Abstract: Nitrogen oxide pollutants are substantially reduced and sulfur dioxide minimized in multisolid fluidized beds by staged combustion of the fuel. The lower combustion region is operated at substoichiometric conditions such that NOx is reduced by carbon and carbon monoxide to nitrogen gas. The upper combustion region is operated at excess oxygen conditions to complete the combustion of char and carbon monoxide. Elevated temperature excursions in the upper region which deter sulfur capture are prevented by recycling cool entrained bed particles therethrough.

Abstract: A method and an apparatus for displacing of particles on and into a loose layer of material, for instance a mineral wool layer (2) by means of an apparatus comprising means, for instance one or more conveyors (4, 10) for continuously advancing the layer of material and means for subjecting the layer of material to a constant force and concurrently therewith an oscillation energy within the acoustic area. The constant force may be applied in that the conveyor is mounted sloping downwards in the advancing direction whereby the gravety force is the constant force, or it may be a flow of air which is blowing against and which is allowed to pass through the layer of material. The oscillation energy may be provided by means of one or more sound emitting means (9, 14) mounted above the layer of material and preferably co-operating with a collection means (7, 12) mounted underneath the layer of material. By the method and the apparatus particles may be expelled from the layer of material or particles supplied to the surface of the layer of material may be forced into and distributed in the interior of the layer of material or both operations may be carried through concurrently.

Abstract: Fuel and combustion gas are supplied to the blast pipes and tuyeres of a blast furnace through injection lances which have an inner tube and an outer tube. The inner tube is generally used to carry the fuel, while the space formed between the inner and outer tubes is used to carry the combustion gas. Such a lance can have a heat resistant tip which has a bore for forming an extension of the inner fuel supply tube, and which also has a number of helical channels disposed about the bore for forming an extension of the space between the tubes. It is advantageous to have more than one such lance in each blast pipe and to have the lances extend obliquely into the hot blast channel that is formed by the blast pipe and the tuyere.
