Abstract: Abstract The preferred instrument disclosed is a portable X-ray diffractometer for measurement of residual stress in metallic specimens, especially large structures, such as bridges, pipelines etc.  The instrument consists of a pair of position sensitive detectors arranged to be mounted in fixed positions relative to the specimen.  An X-ray source that projects a collimated incident beam onto the area of the specimen under examination is located between the detectors so that each receives a diffraction line.  The source is scanned stepwise in an arc about the specimen area, while the specimen and both the detectors remain fixed.  The diffraction lines received in each detector are stored in a computer as histograms of intensity values. For each angular relationship between the incident beam and the chosen direction of strain measurement, a series of such intensity values corresponding to a given diffraction angle for successive diffraction lines is averaged and a resultant diffraction line obtained for each detector.  To keep the mean strain directions constant and achieve a constant range of grain orientations for all diffraction angles, the instrument restricts the intensity values so averaged to those that fall within a virtual window.  This window is moved along the channels, one or more channels per scanning step.  The two resultant series of averaged values are examined to find peaks or other characteristics of the diffraction line and the angular relationships corresponding thereto.  This knowledge enables determin-ation of lattice strains in two directions, the two strains determining the stress in the specimen surface.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention is concerned with casting resins made from acrylic acid esters, with a high content of finely dispersed fillers.  According to the invention, the casting resins contain a mixture of organo-silicon compounds with functional groups and metal acid esters of metals of Sub-groups IV and V of the Periodic System of the Elements.  The functional group of the organo-silicon compound is ethylenically unsaturated and connected with the silicon atom either directly or through alkylene groups. The addition of this mixture to the casting resin known per se achieves a lowering of viscosity of these resins which are employed chiefly for the production of sanitary articles.

Abstract: ABSTRACT            A system is disclosed for treating blood, with the objective of reducing the functioning population of a blood constituent.  According to the method, blood is passed through an ultraviolet radiation field in the presence of a dissolved photoactive agent capable of forming photo-adducts with receptors on the constituent to effect covalent bonding between the photoactive agent and the same.  If desired, the blood to be treated may be separated to provide a blood fraction rich in the constituent sought to be reacted and low in any blood component which absorbs UV radiation, as or example by continuous centrifuging, which fraction is then irradiated with UV radiation in the presence of the dissolved photoactive chemical agent.

Abstract: A  B  S  T  R  A  C  T         A high-pressure, low-capacity pump comprises a rotor of a smooth, planar, circular surface rotating in a pump casing provided with a stator surface      facing the rotor surface at a short distance.  The stator surface      is in the shape of a circular, flat-topped ridge having its center displaced in respect of the rotor center by a given distance.  The circular ridge is characterized by that it is bisected along a line extending through both the center of the circle and the rotor center and that it is of different height on both sides of the bisecting line, creating a respective narrow gap (h) and a wide gap (H) between the ridge and the rotor surface.  A fluid inlet      is provided in the casing on the outside of the circular ridge and a fluid outlet      on the inside of the ridge.  Owing to the eccentricity of the rotor and the stator ridge more fluid is drawn by the drag of the rotor surface into the space defined by the stator ridge through the wide gap than escapes through the narrow gap, whereby the pressure increases inside the stator space and drives the fluid out through the fluid outlet.

Abstract: METHOD AND APPARATUS FOR GAMMA RAY WELL LOGGING            ABSTRACT          A radioactive logging source carried by a logging tool injects gamma rays into the formation.  A detector generates a pulse for each gamma ray incident upon the detector having an amplitude proportional to the gamma ray energy.  Electrical signals corresponding to each such amplitude are delivered to the surface. These incident gamma rays originate from the formation as well as from a monitor source of gamma rays of known energy adjacent the detector.  An energy peak from the gamma ray energy spectra transmitted to the surface corresponding to gamma rays of known energy from the monitor source is accurately identified.  At the surface, the peak is tracked during the logging procedure and a control signal functionally related to observed monitor peak shifts generated and delivered to the logging tool.  A control circuit alters magnitude of the high voltage supply providing power to the detector in response to the control signal.
