Granted: 1982-04-27
Abstract: ABSTRACT OF THE DISCLOSURE         There is disclosed a temperature indicator particularly useful as a steam trap monitor.  The temperature is indicated through the action of a composition of matter placed on an absor-bent layer and formed of (1) a solvent made of substance(s) adapted to change from a solid state at substantially a predeter-mined temperature to a liquid state and (2) an indicator system formed of substances different from the solvent and which are soluble in the solvent when it is in the liquid state and which can change color visible to the naked eye when the solvent passes from the solid to the liquid state or from the liquid to the solid state.  A representative indicator system is a mixture of bromo-chlorophenol blue and ethyl red and a representative solvent is .alpha.,.alpha.'-dichloro-p-xylene.  The absorbent layer containing the temperature indicating composition is sandwiched between a trans-parent tape for viewing purposes, a layer of adhesive, and a paper backed foil.  Another layer of adhesive is used as the outer layer  for attachment to a steam pipe or the like.

Title: Correction for polychromatic aberration in ct  images
Inventor: NAPARSTEK ABRAHAM
IPC: G01N23/04
Filed: 1979-04-27
Granted: 1982-06-01
Abstract: Abstract A method and apparatus which corrects the polychromatic aberration in CT images, which aberration is produced by the non-linear interaction of body constituents with a polychromatic X-ray beam. A  CT image is processed to estimate the proportion of the attenuation coefficients of the constituents in each pixel element. A multiplicity of projections for each constituent are generated from the original image and are combined utilizing a multidimensional polynomial which approximates the non-linear interaction involved. An error image is then generated from the combined projections and is subtracted from the original image to correct for the polychromatic distortion.

Abstract: METHOD FOR MOLDING REINFORCED POLYMERIC ARTICLES        Abstract of the Disclosure The formation of a composite formed by spreading a li-quid thermosetting resin over a continuously moving plastic film or sheet is disclosed.  Chopped fiber is added and a fabric or veil, such as a dacron polyester cloth, is continuously laid over the top to form a reinforced composite.  This continuously produced thermosetting resin composite is rolled into a coil.  After a maturation period, the plastic film or sheet may be removed from the SMC composite and sections of appropriate size and weight are cut from the coil and placed over the die of a compression molding machine, veil side down, up or both.  The material is then compression molded at a pressure of 500-3000 p.s.i. (35 to 210 kg. per sq. cm.) and a temperature of 100-165°C., and cured into an article.  In another embodiment, the fabric or veil may be first placed on one of the die elements, e.g., the bottom die. SMC is then placed over the fabric to make up the total charge.  The charge is then compression molded under the conditions previously described.  The fabric used has a grab break strength of at least 10 lbs. (4.5 kg.) in both longitudinal and transverse directions, and a tensile elongation of at least 10%, and is sufficiently permeable to permit liquid resin to pass therethrough during com-pression molding.

Abstract: Case 771003 LEVERED HOPPER DOOR LOCK MECHANISM     Abstract of the Disclosure A lever operated lock mechanism for a hopper door is provided which is especially suitable for use on railway hopper cars having hinged double doors.  Included in the lock mechanism is a hook assembly which is pivotally mounted on a housing secured to the door frame or slope sheet of the hopper.  A keeper assembly is attached to the spreader bar joining the double doors for engaging the hook assembly, this engagement being at either of two saddle formations or notches, the first or catch saddle formation being engaged when the lock mechanism is in a catch position, and the second or closed saddle formation being engaged when the lock mech-anism is in a fully closed position.  Movement between the catch position and the fully closed position is greatly facili-tated by fulcrum means for receiving a lever bar by which a workman can readily close the hopper doors.  Pivotally mounted to the mechanism is a locking latch for abutting engagement between the housing and the hook assembly to thereby wedgingly lock the lock mechanism in its fully closed position.

Abstract: OILFIELD PUMP STROKE MONITOR                    Abstract of the Disclosure The pumping rate of an oil well pump or other recurring event is determined by providing a force sensor, such as an accelerometer, and a transmitter arranged in a housing adapted to be affixed to the pump piston rod or drive train which move in a vertical plane.  As the piston rod or drive train moves, the sensor measures gravitational and centrifugal forces, the former providing a sinousoidally varying sensor output having a period equal to the rotational or reciprocal period of the piston rod or drive train.  The transmitter is a battery powered R.F. device which is activated once each stroke or revolution by an amplifier-detector coupled to the output of the force sensor.  A one-shot multivibrator is used to transmit a short burst during the on-time and such burst may be modulated fox better noise rejection by the receiver.  The receiver is located remote from the sensor/ transmitter package and comprises an R.F. detector, amplifier and, if required, a demodulator.  Each output pulse from the receiver circuit represents one rotation or oscillation of the machine element.     -1a-

Abstract: TITLE      A PROCESS FOR MAKING A CELLULATED MATERIAL             ABSTRACT OF THE DISCLOSURE        Where a formulated glass cullet is utilized as a por-tion of the pulverulent batch material, the cellular material is prepared by first grinding the glass cullet in a ball mill with a cellulating agent such as carbon black until the pul-verulent material attains an average particle size of about 4 or 5 microns. The pulverulent batch containing the glass cul-let and cellulating agent is then sintered at a sintering temperature for a sufficient period of time to permit the glass cullet material to soften and coalesce and increase in density without, however, cellulating the glass batch. The sintering process is then interrupted and the sintered material may be cooled and crushed to a size that passes through a United States 10 mesh screen. The crushed and screened sintered material is then positioned in a suitable mold and subjected to a cellulating temperature of between about 1600°F (870°C) and 1650°F (899°C) for a sufficient period of time for the cellulating agent to react and cellulate the sintered batch and form a cellulated material. The resultant cellulated material is then quenched to terminate the cellulating process, removed from the mold and thereafter annealed. With the above process, it is possible to immediately subject the sintered material to the elevated cal-lulating temperature rather than slowly advancing the temperature from slightly above the sintering temperature to the cellulating temperature. In this manner the time required to cellulate the sintered batch is reduced substantially. The above process may also be utilized with a pulverulent batch comprising a combina-tion of minerals and commercial chemicals that have not been melted to form a glassy type material, such as the glass cullet above described. By first sintering the pulverulent batch and thereafter heating sized sintered particles to a cellulating temperature, flaws such as folds and uneven densities frequently found in cellulated material are eliminated.
