Abstract: The present invention contemplates a process for the removal of impurities comprising amides, but which may include other impurities such as amines, from a solution of the nitrites and impurities. A reaction mixture is first formed and to that reaction mixture, 0.5 to 3 wt % of approximately 60% H2SO<SUB>4 </SUB>is stirred in at room temperature and atmospheric pressure for a time effective for the removal of the amide impurities. Typically, after about 30 minutes, the amide impurity is removed into the lower, dark acid layer, probably as a salt. The remaining nitrile, after decantation or filtration, is still colored but is substantially free of amide. In a to second step, at room temperature or at a temperature of up to ~80° C., color can be removed from the nitrile by stirring the acid-washed nitrile with 0.5-5 wt % of clay (bentonite), charcoal, zeolitic type materials, mixtures thereof and the like.

Abstract: A container closure moulded from plastics material has a top 10, an internally screw-threaded skirt 11, and a tamper-evident ring 13 connected to the bottom edge of the skirt by frangible bridges 15. The radially inner surface of the ring 13 is formed with an odd number of evenly spaced inwardly projecting protrusions 16 for engaging under a security band on the neck of a container. The use of an odd number of protrusions ensures that no two protrusions are diametrically opposite each other and in consequence permits the closure to shift or wriggle diametrally during application of the closure to a container and thus facilitates movement of the ring 13 past the security band. An annular groove 20 is formed on the radially-outer surface of the ring at a location axially between the upper ends of the protrusions 16 and the bridges 15, and serves to form an annular hinge about which the lower parts of the ring 13 can pivot during application of the closure.

The die halves 60 and 62 of each pair are relatively radially reciprocable to grip or release a workpiece 102, 104 and the two pairs of die halves are relatively axially reciprocable to effect cold pressure welding together of end portions of the workpieces 102, 104. Adjoining end faces of the die halves are formed with nose portions 100 having inner anvil edges for effecting welding flash removal from the workpieces. In operation, the die halves are moved in sequence to grip the workpieces; to urge the ends of the workpieces together to form a cold pressure weld upset zone; to release the workpieces; to grip one of the workpieces; to urge the gripped workpiece axially relative to a pair of anvil edges to clear flash material from the upset to maintain the cross-sectional area at the weld upset zone substantially constant; and to re-position the upset weld zone centrally of the nose portions to repeat the sequence. Removal of the flash material intermediate consecutive weld upsets is effected in alternate directions. The anvil edges may be staggered, angled or of helical form to enhance the shearing effect to clear the flash material from the upset weld zone.

Abstract: An electromagnetic shielding panel (1, 2, 3, 4, P5) incorporates at least two electroconductive coatings (10 and 6, 7,8). In two of the panels (1,2) the coatings are carried on separate sheets of float glass (5,9), one of the coatings 10 being an anti-abrasive coating is on the outermost surface of the glass (9) in the panel arrangement, while the other coating (6,7,8) being a relatively soft abrasive-sensitive coating, e.g. silver, is on the innermost of the glass 5 in the panel arrangements. In other panel arrangements (3,4,P5) the two coatings are located on opposing sides of one glass sheet 9 and on two of the panels (3,4) a plain sheet of float glass (11) is employed to protect the soft silver coating (6,7,8). In another panel (P5) a sheet of glass (9) carrying an anti-abrasive coating (10) is employed. The panels are of the double glazed type (Fig. 1, Fig. 3, Fig. 5) and the laminated type (Fig. 2, Fig. 4). This invention utilises the enhanced capacitive coupling (C) between the two coatings (10 and 6,7, 8) to effectively earth the innermost silver coating (6,7,8) by way of the anti-abrasive coating 10 without any direct electrical connection being required to be made to the innermost coating (6,7,8).

Abstract: The present invention relates to methods and test strips for performing nucleic acid hybridizations on a porous chromatographic material having the capacity for rapid chromatographic solvent transport of non-immobilized reagents and reactive solution components by means of a selected chromatographic solvent. The strip includes a first end or contact site, at which chromatographic solvent transport begins, a second end, at which chromatographic solvent transport ends, and at least one zone positioned between the first and second ends. The zone is impregnated with a capture nucleotide sequence which is immobilized against solvent transport and which is capable of hybridization with a complementary nucleotide sequence or probe so as to render it immobilized in the capture zone. The strip may further include a probe zone between the first end and the capture zone, wherein a labeled probe is impregnated such that it is mobilized by the solvent and transported to the capture zone where hybridization can occur. Interfering sample components and unhybridized nucleic acids are cleared from the capture zone by chromatographic solvent transport to form an inherent wash.
