Abstract: ABSTRACT OF THE DISCLOSURE:     A system, suitable for use as an identity seal for an object, such as a container for fissile material, comprises a body including a cap for fitting over one end of the object, and a recess which contains a material such as "ARALDITE"          (Trademark) or aluminium acting as a matrix for a plurality of inclusions of e.g. bronze embedded therein in a random confi-guration. The recess is closed by a cover which includes a central electrically conductive part. Also embedded in the matrix material and constituting further "inclusions" are two piezo electric crystal transducers each electrically connected to the central cover part. In use, the transducers are elec-trically connected via the central cover part to external ultrasonic testing apparatus to provide a unique output indi-cative of the particular structure of the seal particularly the inclusion configuration and hence providing a unique "identity" and hence indication of integrity for the seal.     Tampering with and/or removal of the seal will change its structure in some way so that subsequent ultrasonic testing produces a different output, revealing the occurrence of the unauthorized event.

Abstract: ABSTRACT OF THE DISCLOSURE            The sulphur emissive capability, on combustion, of coke which is formed during upgrading of sulphur-containing heavy crude oils, including oil sands bitumen, or residua is decreased by the addition of slaked lime or calcium oxide to the heavy crude oil prior to coking.  The presence of the slaked lime or calcium oxide leads to an increased yield of liquid distillates at coking temperatures of about 450° to about 500°C.  Ash remaining after combustion of the coke may be leached to recover nickel and vanadium values therefrom.

Abstract: ABSTRACT       Method and composition for detecting flaws in a workpiece utilizing either white light or ultraviolet light wherein a penetrant solution is applied to the surface of the workpiece, the penetrant solution con-taining a rhodamine dye dissolved in solvent, the dye possessing an inherent color and being capable of fluores-ing under the influence of ultraviolet light.  The excess penetrant is removed from the surface in accordance with usual practice, while leaving penetrant entrapped in any surface flaws.  An improved developer is applied to the surface, the developer consisting of a suspension in-cluding a finely divided developer powder suspended in the same dye solvent as in the penetrant in a sufficient amount to lower the concentration of rhodamine dye in the entrap-ped penetrant below that at which quenching of fluorescence occurs.  The indications thus produced under both visible light and ultraviolet light are distinct and non-blurring, enabling the piece to be inspected under either type of light source.

Abstract: MAGNETIC COUPLING FOR A WEIGHING BALANCE ASSEMBLY               Abstract of the Disclosure A magnetic coupling between the sample support shaft and the internal weighing mechanism of a weighing balance assembly is provided which permits transverse movement of the shaft when it or a sample supported by it are bumped or jarred. Generally, the internal weighing mechanism of a weighing balance is quite sensitive to the unavoidable bumping and jarring which occurs during the loading and unloading of a sample.  Because the magnetic coupling permits movement of the shaft, no damaging forces or torques are transmitted to the weighing mechanism.  The magnetic attraction between the shaft and coupling is sufficient to insure that the shaft remains in an upright position during normal operation.

Abstract: ABSTRACT OF THE DISCLOSURE           A process for piloting and guiding a projectile in the terminal phase in which the correction is obtained by means of a barrel of (n) impellers with lateral nozzles.          Combustion of the first is triggered off when the rotational speed of the sight line reaches a triggering threshold.  The mean thrust of each of the impellers which discharge suc-cessively and completely during a single revolution of the projectile is directed in the same direction located with respect to an absolute system of reference axes tied to the target.  Detection of the target by optronic means enables the moment when this triggering threshold is reached to be determined.

Abstract: Abstract The optical elements of a copier  are automatically aligned by positioning the elements under the control of signals from an image-dissecting  scanner.  The scanner  mounted to receive the image normally pre-sented to the photoconductor,  examines a master document placed in the position normally occupied by a document to be copied.  Optical adjustments are made as a function of the examination of lines on the master document by the scanner.  The contrast between a line and its background   is maximum when optical elements between the master document and the scanner provide the sharpest focus of the line image to the scanner.  Signals from the scanner for a plurality of lines on the master document determine optimum posi-tioning of the optical elements.  The scanner deter-mines the apparent spacing between lines which are a known distance apart on the master document  to position the optical elements for a desired magnifi-cation.  The positions of selected lines  examined by the scanner,  relative to absolute reference points are used to align the master document support for subsequent copying of original documents.
