Title: Process for purification of linear paraffins with recycle
Inventor: DICKSON CHARLES T
IPC: C10G25/03
Filed: 1991-06-04
Granted: 1999-01-05
Abstract: A process for purifying linear paraffins in which a hydrocarbon feedstream containing linear paraffins contaminated with aromatics, sulfur-, nitrogen-, and oxygen-containing compounds, and color bodies, and also containing up to about 5 wt% desorbent from effluent recycle, is contacted with a solid adsorbent such as a NaX zeolite or zeolite MgY; after adsorption the adsorbent is desorbed with an alkyl- substituted aromatic desorbent, such as toluene. As the adsorbent bed is being desorbed, the initial effluent from the adsorption cycle will contain levels of desorbent and may be recycled to the hydrocarbon feedstream. Previous to the removal of impurities from the adsorbent by desorption, the desorbent displaces interstitial linear paraffins which are also recycled to the hydrocarbon feedstream.

Abstract: A method and apparatus for determining the position and orientation of a remote object relative to a reference coordinate frame includes a source having a plurality of field-generating elements for generating electromagnetic fields, a driver for applying, to the generator element, signals that generate a plurality of electromagnetic fields that are distinguishable from one another, a remote sensor having a plurality of field-sensing elements for sensing the fields generated by the source, and a processor for processing the outputs of the sensing elements into remote object position and orientation relative to the source reference coordinate frame. The processor compensates the position and orientation values as a function of displacement of either the field-generating elements from a common center, or the field-sensing elements from a common center, or both. Techniques are disclosed for compensating for small-scale non-concentricity in order to overcome imperfections in the orthogonal coil sets wound on a common core, each set defining the source or the sensor.          Techniques are also disclosed for compensating for large-scale non-concentricity to allow physical separation of the coil set defining  the source or the sensor to dispersed locations that may be more desirable for a particular application.

Title: Method and apparatus for cementing intramedually bone prosthesis
Inventor: CARBONE JOHN J
IPC: A61F2/36
Filed: 1993-06-18
Granted: 2004-08-17
Abstract: An intramedullary bone prosthesis to be rigidly cemented into position in the femur, and also applicable to total knee and shoulder replacement operations, is provided as an improved surgical technique. The prosthesis is composed of a femoral head base, a femoral head post, a long femoral stem, a cement canal along its longitudinal axis, a spacer, a collar, and a distal restrictor. The prosthesis is placed into the prepared medullary canal. With collar in position, a bone cement injector is readily threaded on to the proximal portion of the cement canal. Cement is injected and subsequently travels down through the canal, through the spacer, and eventually exits openings at the bottom of the spacer. The distal restrictor plug halts downward cement travel, thus initiating an upward, retrograde filling of the void in between the prosthesis and the cancellous bone wall.      The cement reaches the collar or cement restrictor, thus proximally dislodging all air bubbles, blood, and blood products. Finally, during curing, the cement in constantly and evenly pressurized by means of the cement injector, and excellent cement interdigitation is achieved.

Abstract: In a receiver for use in demodulating a modulated wave modulated by a digital data signal arranged within a preselected channel to produce a reproduced data signal by the use of a local frequency signal of a local frequency, a VCO and a PLL circuit are intermittently put into active states with reference to an offset frequency between a channel frequency and the local frequency. The PLL circuit is put into the active state for a time interval determined by the offset frequency before reception of the preselected channel while the VCO is put into the active state during the active state of the PLL circuit and during reception of the preselected channel.          A duration of the active state in the PLL circuit becomes long when the offset frequency does not fall within a predetermined range determined by predetermined offset frequencies and, otherwise, the duration of the active state in the PLL circuit becomes short. The offset frequency is detected by a frequency detector which produces a control signal appearing only when the offset frequency is present outside of the predetermined range.          The control signal is sent to a control circuit for controlling battery saving operations of the VCO and the PLL circuit.

Abstract: The present invention demonstrates a method and a device in the technique of using an image sensing member, preferably a CCD ("Charge Couple Device") cell instead of a film sensitive to X-ray radiation. The method and the device is applicable to a general X-ray arrangement without any necessary direct connection between the image sensing member and the X-ray arrangement. A number of detector points for X-ray radiation are provided at or in the CCD cell. The method and device of the present invention result in minimizing of the radiation dose to exactly that which is needed for exact imaging exposure of an image, and therefore more images may be obtained within the same total normal radiation dose.
