Abstract: APPARATUS FOR THERMAL PRINTING                 ABSTRACT OF THE DISCLOSURE          Apparatus for thermally printing images, such as color images, on a print medium.  The medium is moved repeatedly from a reference position through a printing region, as by rotating the medium on a platen.  Thermal print elements are disposed at the print region and are selectively energizable to cause images, such as color images, to be printed.  A movable web of thermally transferable material has a run interposed between the print medium and the thermal elements at the print region.  In one embodiment, the web is provided with successive frames of respectively different colors of thermally transferable material arranged in repeated sequence.  Energizing signals are supplied to the thermal elements representative of the image to be printed; and an image is printed in a color corresponding to the color frame then disposed at the printing region.  Successive passes of the print medium are made in order to print images of the remaining colors in the sequence of frames on the web.

Abstract: PUMP              ABSTRACT OF THE DISCLOSURE       A piston type fluid pump which can maintain its prime even though the source of fluid from which the pump draws its supply becomes empty.  The pump is capable of pumping its discharge into a pressure vessel as well as to the atmosphere if desired.  The pump assembly includes a discharge chamber that receives discharged fluid from the pump and for ultimate delivery to the outflow of the pump assembly.  The discharge chamber is of a volumetric size at least equal to or greater than the volume of the effective pumping chamber of the piston so that any air that enters the pumping chamber from the supply or inlet side of the pump remains at the top of the pumping chamber and is discharged into the discharge chamber and the pumping chamber remains full of fluid and consequently primed.          The pump assembly is arranged so that the discharge chamber is located above the pumping chamber whereby fluid from the discharge chamber can flow back into the pumping chamber thereby filling the latter with fluid and maintaining it free of air.

Abstract: PPI TO RASTER DISPLAY SCAN CONVERTER     Abstract A raster display apparatus for converting radar input data which is formatted to produce a Plan Position Indicator (PPI) presentation on a cursive display to a format which achieves a PPI type image on a raster display.  The apparatus generates radar images on a raster display screen which appear as targets having continuous arcs of the proper length around the placement position of a radar.  Average video levels within successive discrete fixed azimuthal standard angle increments are stored in a radial buffer memory for various increments of range.  These video levels are used for all points within the presently active standard angular increment.  Radial distance of a given image is computed for changes in orthogonal components such as X or Y using simple prestored sine and cosine functions.  Conversion calculations comprise primarily additions using adders.  The video amplitude of the image displayed is equal in amplitude to the video level of the input data stored in the radial video buffer memory for the standard angle being processed.          Processing of successive standard angle increments proceeds in approximate synchronism with the input data being provided in a cursive display format.

Abstract: Abstract METHOD AND APPARATUS FOR REMOVAL OF ENCLOSED INTRA-ARTERIAL DEPOSITS A device for safe removal of abnormal deposits, primarily in the human body, where differential cutting proper-ties provide for fracture of hard matter while safely preserving soft tissue. The device includes a rotating cutting tool having spirally shaped cutting flutes having hardness-differential cut-ting properties. The tool is driven from outside the body by means of a flexible drive shaft at greater than 2000 revolutions per minute. A channel is incorporated in the drive shaft for adding or removing chemical matter from the internal body space to provide systematic removal of cutting debris from abnormal deposits. The cutting tool has fluid ports which communicate with the drive shaft channel. The fluid ports may be at the nose of the tool as well as around its circumference. In the latter instance, the ports extend from in front of a cutting flute into a center cavity with a circumferential component so that rotation tends to force blood into these ports. External mass transfer machines aid in injecting or withdrawing material, such as cutting debris. Auxiliary instrumentation, such as fluoroscopy and pressure measuring apparatus, are helpful in the clinical procedure. Multiple operational cycles are easily implemented to gradually dissect the deposit while periodically reestablishing physiological viability, such as blood flow in vessels.

Abstract: ABSTRACT OF THE DISCLOSURE      A process for removing halogenated aliphatic and aromatic compounds, e.g., polychlorinated biphenyls, from petroleum products by solvent extraction.  The halogenated aliphatic and aromatic compounds are extracted from a petroleum product into, a polar solvent by contacting the petroleum product with the polar solvent.  The polar solvent is characterized by a high solubility for the extracted halogenated aliphatic and aromatic compounds, a low solubility for the petroleum product and considerable solvent power for polyhydroxy compound.  The preferred polar solvent is dimethyl-formamide.  A miscible compound, such as, water or a polyhydroxy compound, is added to the polar extraction solvent to increase the polarity of the polar extract-ion solvent.  The halogenated aliphatic and aromatic compounds are extracted from the highly-polarized mixture of water or polyhydroxy compound and polar extraction solvent into a low polar or nonpolar solvent by contacting the water or polyhydroxy compound-polar solvent mixture with the low polar or nonpolar solvent. the halogenated aliphatic and aromatic compounds and the low polar or nonpolar solvent are separated by physical means, e,g., vacuum evaporation.  The polar and nonpolar solvents are recovered from recycling.

Abstract: ABSTRACT: Bit synchronization arrangement for a data modem or data receiver.           In an asynchronous transmission mode, the bit synchronization arrangement receives data signals in the form of binary pulse trains (at A). It comprises an oscillator (3) whose output signal (at C) has a frequency Fos approximately equal to twice the binary rate of the pulse trains and a transition detector (1, 22) which supplies a calibrated voltage pulse (at B2) at each data signal transition. According to the invention, the oscillator supplies a triangular internal signal (at D) at the frequency Fos and phase correction means (2) are provided to reduce the algebraic value of the slope of this signal during each calibrated pulse so as to produce a predetermined constant advancing or delaying phase shift according as the calibrated pulse occurs during a negative or a positive ramp of this signal.

Abstract: APPARATUS FOR NEUTRON-CAPTURE TUMOR THERAPY          ABSTRACT OF THE DISCLOSURE A tumorous patient is injected with a compound including an element that accumulates in tumors and that has an isotope which emits an alpha particle in a neutron capture reaction.  The patient is positioned in front of a radiation beam that has been filtered to remove most neutrons having energies above 30 KeV and most thermal neutrons, leaving predominantly epithermal neutrons which are moderated to a thermal level by outer layers of tissue and are captured by the incorporated isotope.         A radiation beam having neutrons with a wide distribution of energies is filtered with aluminum and sulfur filters, whose cross sections complement each other in providing a beam with energies predominantly in the epithermal range.  The filter mass attenuates the gamma radiation.  Beams with lower ratios of undesirable gamma radiation to epithermal beam intensity can be attained with filter combinations which include liquid argon.  A poor geometry filter of bismuth or lead can also improve the gamma to neutron ratio.  Preferably the beam is filtered through a thermal neutron filter as well.
