Abstract: A compact, robust, wear resistant, and high performance electrically insulating gap sub for use with borehole EM Telemetry is disclosed. In one embodiment, the gap sub may include an externally threaded mandrel separated from an internally threaded housing by a dielectric material. Additionally, some embodiments may include an external gap ring for separating the upper and lower electrical halves of the sub which offers structural support, acts as the primary external seal, and provides an abrasion resistant non-conductive length on the exterior. Some embodiments may include torsion pins to prevent the possible unscrewing of the dielectric filled threaded sections should the dielectric material become damaged or weakened.

Abstract: A process and an apparatus for the production of a new reduced fat culinary sauce which comprises mixing the ingredients of a reduced fat culinary sauce whereby part of the fat present in a regular culinary sauce is substituted by water, controlling the water activity to a value less than 0.95, mixing or precooking below 160.degree. F. and then processing for a minimum of 0.87 minutes by continuous steam injection and holding at a temperature of at least 160.degree. F.

Abstract: Radiation imaging apparatus includes first and second bodies of material capable of producing scintillations in response to bombardment by ionizing radiation, each scintillation producing body having a surface bordered in part by an edge, the edge of the first body adjacent the edge of the second body. The radiation imaging apparatus also includes joining members located between the edges of the first and second bodies for transmitting light emitted from the edges of the first and second bodies as a result of scintillations produced by the first and second bodies, a collimator for collimating the ionizing radiation, and photomultiplier tubes for converting the scintillations to electrical outputs including a plurality of scintillation sensing units on the first and second scintillation producing bodies and on the joining body.

Abstract: The apparatus reduces scatter in radiation imaging and may be used with a detector of ionizing radiation that is partly unscattered and partly Compton scattered. The detector produces an energy signal representing values of energy of the radiation and produces coordinate position information for the radiation. Data storage means for holding numerical values and means for displaying an image based on the numerical values in the data storage means are also used with the inventive apparatus. The scatter reduction apparatus includes circuitry responsive to the energy signal from the detector for producing first and second signals which indicate whether each value of energy represented by the energy signal at a given time is in a first energy range or in a second energy range less than half as wide as the first energy range and having at least some energies in common with the first energy range.

Abstract: Radiation imaging apparatus includes a substantially tubular body of material capable of producing scintillations in response to bombardment by ionizing radiation and means for converting the scintillations to electrical outputs including a plurality of scintillation sensing units disposed both along and around the outside of the substantially tubular body. A radiation imaging method processes outputs of the scintillation sensing units, which have axial positions and positions relative to first and second coordinates perpendicular to a longitudinal axis of the tubular body.

Abstract: Anthranilic acid has been anchored to polystyrene, and rhodium, palladium, platinum and ruthenium complexes of this modified polystyrene have been prepared. These catalysts will reduce a variety of olefinic and aromatic hydrocarbons, and also nitrile, nitro and carbonyl functional groups, said carbonyl groups being present in either ketones or aldehydes.
