Granted: 1993-04-20
Abstract: An object is exposed to penetrating radiation at each of a plurality of partial rotations of the object. Radiation transmitted through the object strikes a separate sheet of radiographic film for each exposure to record an entire radiographic image of the object for each angular orientation. The radiographic images are digitized and stored in the memory of a computer. Each digitized image is registered by determining the error of rotation and center of rotation for each digitized image and correcting for the error of rotation by rotation and translation of pixel values. One or more displacement values are selected in correspondence with one or more desired levels of view and the digitized images are displaced according to the selected displacement values. The displaced images are then combined to produce images representative of the selected levels of view. Image planes non-parallel to the film image plane may be selected and interactive image enhancement and manipulation are provided. Data compression is accomplished in order to minimize the memory requirements of the images prior to general storage.

Abstract: Abstract The present invention is achieved with a control unit for a PWM inverter for comparing (8) a voltage command signal (7) with the fundamental of the inverter's output voltage waveform and for comparing (11) the result with a carrier signal (10) and using that result to keep the output voltage waveform equal to the voltage command signal.  The use of the output's fundamental for feedback eliminates the prior art need to use slight delays in the inverter's switching stage thereby removing the prior art torque ripple and consequent vibration problems particularly at low speed and furthermore enables smoother stopping and starting control using variable speed ranges of several hundred to one.

Granted: 1992-12-22
Abstract: IMPROVED COMPRESSION COUPLING         ABSTRACT OF THE DISCLOSURE    A coupling is provided for joining segments of plastic pipe. The coupling includes a body portion having an inner bore opening to an enlarged outer bore. A metal stiffener tube having a flange at one end is inserted into the bore of the body until the flange contacts an internal stop. An elastomeric gasket having a substantially rectangular cross-sectional area encircles the stiffener. When the coupling is tightened a corner portion of the gasket initially engages a sloped surface in the enlarged outer bore of the body to initially load the gasket for sealing. A rigid washer encircles the stiffener and contacts the outside end of the gasket. A grip ring, comprising a frustoconical radially outer surface, an inner surface with gripping members, a segmented lateral slot, and a resilient lip around one end, encircles the stiffener so that the lip is in contact with the washer. A connecting nut having a frustoconical bore for mating with the outside surface of the grip ring surrounds the stiffener and engages the enlarged bore of the body. The plastic pipe is inserted into the bore and around the stiffener. Tightening of the connecting nut into the enlarged bore causes axial movement and radial compression of the grip ring around the pipe and compression of the gasket by axial force of the nut and the washer. The compressed gasket provides a seal between the bore of the body and the outer surface of the plastic pipe.

Abstract: A blood pressure monitor having a motor driven air pump for inflating an blood pressure cuff, and a control system for controlling the voltage applied to the motor to regulate the rate at which the cuff is inflated The control system utilizes a microprocessor to calculate a desired inflation rate and then compare the desired inflation rate with the actual inflation rate to generate a control signal in the form of a pulse-width modulated square wave. The square wave is low-pass filtered to generate a voltage reference that is applied to one input of a comparator. The other input of the comparator receives a feedback signal indicative of the voltage applied to the motor. The comparator generates a square wave having a duty cycle that is a determined by the polarity of the comparison at its inputs. The square wave modulates a semi-conductor switch which, in turn, controls the voltage applied to the motor.

Abstract: A method of flue-gas cleaning comprising the separation of water-soluble substances from flue gases containing water vapour. The invention is characterized in that the flue gases are caused to be cooled by direct contact between flue gas and atomized water in two or more separation steps, where in a separation step (2) subsequent in the flow direction of the flue gases the flue gases are cooled by atomized water to a temperature, at which the water in the flue gases is condensed out, which water is collected and thereafter both recirculated for utilization in said subsequent separation step (2) and introduced into a separation step (1) prior in the flow direction of the flue gases. In said prior separation step the water is atomized and meets uncleaned flue gases, the water-soluble and potentially water-soluble substances of which thereby are solved in the atomized water. The water thus impurified is collected for further treatment.
