摘要： Apparatus for resistance welding an elongate seam in a tubular article, comprises a first electrode wheel outside the article, a second electrode inside the article and a continuous electrode wire arranged to pass over the electrodes to provide surfaces of contact between the electrodes and seam material. The second electrode has a stationary block having a guide surface of like curvature to that of the outer electrode wheel so that the contact arcs of wire passing over the guide surface with the seam material is substantially equal to the contact area of wire passing over the external wheel. The use of this stationary inner electrode improves the weld of geometry and permits welding of can bodies of relatively smaller diameter without use of mercury contact bearings.

摘要： A machine for filling packaging containers with a flowable product comprises a control valve in the form of a plug valve having a body defining a bore forming a frusto-conical valve seat, a plug having a complimentary frusto-conical surface, and a valve chamber for pressurized fluid formed at the wider end of the plug. The chamber communicates with the bore. The plug is axially displaceable between a first position, in which the frusto-conical surface seals against the valve seat and in which it is rotatable to control flow through the valve, and a second position, in which it is withdrawn into the chamber to provide clearance between the mating surfaces of the plug and the seat but retaining clearance between its wider end and the opposite surface of the chamber so that all surfaces of the plug are exposed for cleaning and sterilization.

摘要： A method of making a metal can end with a tear-open plastics closure, for a can intended to be resistant to leakage when subject to internal pressures, such as arise from carbonation of a beverage or thermal processing, wherein the undersurface of the can end is provided with a plastics coating, and the can end is pierced to form an aperture with a peripheral downturned flange at an angle of 70.degree. to 110.degree. to the plane of the can end and having a flat end. A one-piece ring pull closure is injection-moulded onto the can end from a plastics material resistant to softening at up to at least 65.degree. C., without additional heating of the metal, so as to fill the aperture, bond with the coating, and enclose the flange, with a residual thickness below the flange of 0.125 to 0.5 mm. The thickness of the plastics material of the closure is such that it can be sheared against the flange when the ring pull is pulled manually. The residual thickness of the plastics material may be varied around the aperture to increase resistance of the closure to creep, and the aperture may be pear-shaped or may be circular with a separate vent hole.

摘要： A detection system for anaerobic micro-organisms involves the addition to a nutrient medium for the micro-organisms of an indicator species which is electrochemically reducible, soluble in the nutrient medium and consumed by the micro-organisms during growth. Two electrodes are immersed in the nutrient medium and changes in an electrical property of the nutrient medium are monitored. A preferred indicator species is riboflavin.

摘要： A method of removing a layer of cobalt from an underlying nickel surface of an article comprises the steps of immersing at least part of the article in an aqueous solution of a caustic alkali having a pH value not less than 12.5 and preferably not less than 14, and applying an electrical potential difference between the article and a counter electrode which acts as a cathode to strip the cobalt from the article leaving the nickel passive. The method is particularly suitable for removing a defective cobalt layer from a data storage disc so that the disc can be recoated.

摘要： A security document has security printing formed as a moire pattern of two superimposed sets of generally parallel lines. In each line set the line spacing varies progressively along the length of the lines so that each line set has one or more areas in which the line frequency is low and individual lines can be seen with the naked eye, and one or more further areas of high line frequency in which individual lines can only be readily distinguished by using magnification. Futhermore, the thickness of each line varies progressively between relatively large and relatively small values corresponding respectively to the areas of low and high line frequency, the ration of line spacing to line thickness being approximately constant so that the color or tonal density of the security printing is approximately uniform. For additional security the individual line sets are printed in inks of which the colors can be differentiated by the naked eye but not by a reproducing machine used for counterfeiting. One or both of the line sets may additionally or alternatively be printed in an ink having an anti-fraud characteristic such, for example, as water-fugitivity, solvent-sensitivity or UV fluroescence.

摘要： An electro-magnetic induction heater has a heating coil which defines a throat through which a metal strip (moving towards a plastics film laminating station) passes thereby to be heated to a laminating temperature. The coil turns are flexible, and are braced at spaced positions in braces which are mounted for movement towards and away from the metal strip. Each brace has an associated adjustment means. The positions of the respective braces are adjusted during heating, preferably automatically, so as to adapt the coil throat shape to the varying cross section (and/or other characteristics) of the strip to be heated, thereby to ensure uniform temperature distribution across the width of the strip. Under automatic control each adjustment means is operated in closed loop manner by associated actuating means in response to deviation from a reference level of a sensed temperature signal provided by an associated sensor positioned adjacent the emergent heated strip.

摘要： A metal can end (10) has a metal pull tab (16) attached to a score-defined detachable portion (15) of the can end by direct welding of protective polymer coatings (19,20) whose surfaces at least are derived from the same monomer and which are provided on the upper side of the can and the under side of a shank portion (18) of the pull tab. The coatings may be composite films each comprising an inner layer of a bonding resin and an outer layer of a polyolefin, polyamide or polyester. The welding may be effected by heat or preferably by ultrasonic energy.
