Abstract: ABSTRACT OF THE  DISCLOSURE       Process for the conditioning of waste, such as radioactive or toxic waste, whose acidity can inhibit polymerization reactions, e.g. waste containing cation exchange materials.      This process consists of incorporating the waste into a liquid epoxy resin at ambient temperature and then bringing about the polymerization of the resin by means of a hardener, in order to obtain a solid block.      A hardener containing at least one compound having at least one NH2 group in an adequate quantity for blocking the active sites of the cation exchange materials present in the waste or for neutralizing the acidity of the humid waste and for polymerizing the epoxy resin is used.     This process can be more particularly used for conditioning resin beds used for the purification of the water of nuclear power sta-tions.

Abstract: A B S T R A C T      A capsule for administration to a ruminant, comprises two body portions of magnesium or an alloy thereof, pivotally connected for movement between a relatively small cross-sectional configuration in which the capsule can be administered per os into the rumen, and a relatively larger cross-sectional configuration adopted within the rumen to resist regurgitation.  The pivotal connection between the body portions is provided by a resiliently flexible material such as rubber or silicone made electrically conductive by means of a matrix of conductive particles, for example carbon particles.  The flexible material at least partially covers a surface of each body portion.  When the capsule is in the rumen the conductive particles act as a cathode and the body portions as anodes.

The transmission means further includes circuitry for developing a composite baseband signal having a first component comprising the sum of the first and second audio signals, a second component comprising a double sideband suppressed carrier signal formed by amplitude modulating a 2fH subcarrier with the difference between the first and second audio signals, a third component comprising a pilot signal having a frequency fH and a fourth component. comprising a 4fH subcarrier signal frequency modulated according to the third audio signal, where fH represents the horizontal scanning line frequency.  The composite baseband signal may include a fifth component comprising an approximately 5.5fH subcarrier signal frequency modulated in accordance with a first information signal and a sixth component comprising an approximately 6.5fH sub-carrier signal frequency modulated in accordance with a second information signal.  In an alternate embodiment, the fourth and fifth components are replaced by a 5fH subcarrier signal frequency modulated according to the third audio signal.  The composite baseband signal is used to frequency modulate a transmitted main audio RF carrier, the transmitted signal being detected by receiving circuits for reproducing the stereophonic audio signals, the third audio signal and the first and second information signals.

Abstract: ABSTRACT A"MUSICAL THEORY SLIDE RULE FOR STRINGED INSTRUMENTS"  A musical theory slide rule for stringed instruments having a base member 1 with a representation of the neck 3 of the instrument showing the strings 4, frets and colour coded fingering positions.  One or more sliding masks 16, 26 are provided, each relating to a specific chord or scale type (e.g. Major Chords) that can be engaged with the base member and moved longitudinally against an index 18, 19 to highlight the fingering positions for the chord or scale shown by the index (e.g. G Major).  Chord and scale masks may be used simultaneously to show acceptable combinations.  The base member also incorporates calibrations 22, 30 of the chromatic scale and the masks have apertures which reveal only those notes which are contained within the specific chord or scale set on the slide rule.  The chromatic scale calibrations are colour coded corresponding to the colour coding of fingering positions on the neck.    A pentatonic scale cursor 35 is also described for use in highlighting those notes which can be fingered in the pentatonic scale for any particular setting of the slide rule.

Abstract: Abstract of the Disclosure A fastener for securing a sheet metal roof panel to a roof frame with a layer of compressible insulation between the two includes an elongated shank with a tip at one end and a driving head at the other.  The shank either is inserted tip first through a preformed hole in the sheet or through a hole which the tip drills and the shank is driven through the insulation layer.  A first thread on the shank adjacent the tip is driven into the frame and draws a flared portion of the shank through the hole to enlarge the latter and roll over the metal around the edge of the hole.  The rolled over edge then is engaged by a second thread on an enlarged portion of the shank under the head and the plate together with a washer are compressed between the second thread and the head so as to prevent overdrive of the fastener and reduce the possibility of the sheet being dimpled.  Longitudinally extending beads or a third thread on the flared portion produce a smooth and gradual rolling over of the edge of the hole in the plate.

Abstract: HORIZONTAL CRYOSTAT PENETRATION INSERT AND ASSEMBLY             Abstract of the Disclosure An insert for a horizontal cryostat penetration comprises a plurality of foam plugs between which are disposed patches of copper or aluminum foil.  The plugs and foil are disposed in a tubular conduit comprising thin wall, low thermal conductivity material.  This plug provides thermal insulation and significantly reduces the formation of convection currents in the penetration which would otherwise significantly increase the rate of coolant evaporation.  The insert assembly described is designed to be ejected from the penetration upon the build up of excessive internal pressure.  The insert is also preferably disposed within another tubular conduit around the exterior of which there is disposed one or more string-shaped helically disposed lengths of sealing material. Accordingly, when this assembly is inserted within a third conduit, a helical coolant vapor path is formed for exterior venting.

Abstract: ABSTRACT OF THE DISCLOSURE        An improved optical flow sensor for optically de-tecting and measuring the flow of a fluid through a drip chamber assembly.  The sensor comprises an optical energy-emitting chip sealed within a first lens block having a refracting lens in one surface and an optical energy de-tecting chip sealed within a second lens block having a refracting lens in one surface.  The two lens blocks are positioned on the two parallel arms of a a "U"-shaped base with their lens surfaces facing each other across the open space between the arms of the "U".  The drip chamber as-sembly has transparent walls defining a drip chamber, and the lenses compensate for the refractive effects of the walls of the drip chamber assembly on the optical energy passing through.  As drops of fluid fall trough the cham-ber, they intersect the optical energy passing through the chamber and produce a corresponding output signal from the detector.

Abstract: ABSTRACT     An automatic clamp tightener utilizes a pivotally mounted air driven rotating tightener which pivots about a base via the inflation and deflation of a flexible diaphragm.          Sensors are utilized to locate the tightener and sense when a clamp is to be tightened or loosened.  Sensors also detect when the tightener is driven to a stall condition indicating that the clamp is tightened.  The work piece is flattened via two hold down bars which move into and out of engagement with the work piece under automatic control to hold the work piece firmly in place and to pressurize same while the clamp is being tightened.  The tightener and the automatic flattener are mounted on the same supporting frame which moves laterally along the location of the clamps to be adjusted.
