Static charges on rapidly moving articles or materials are neutralized by directing a pair of discharge devices A1 and A2 having uncoated exposed conductive points 12 toward a particular zone transverse to the direction of travel of the articles or materials and energizing the devices A1 and A2 by A.C. supplies which are 180 degrees out of phase to prevent the occurrence of cyclically charged or non-neutralized areas. In the arrangement shown, the devices A1 and A2 are on opposite sides of a moving web B and are energized by separate generators G1 and G2. Alternatively, the devices A1 and A2 may be on the same side of the web and may be connected to the ends of a transformer secondary winding having an earthed centretap (Figs. 2 and 2A, not shown). In a further alternative embodiment (Figs. 4 and 5, not shown) powder moving through a conduit is treated by a ring of discharge devices of which alternate ones are connected together to form two nets which are energized 180 degrees out of phase.

The carriers are moved by the action of magnetic rails (18) (Fig. 2, not shown) disposed beneath the paths 15, 17. Since all the articles are initially on a central path arriving at 13, no rail is registered for the path 17. If however, path 16 or 17, is selected (according to a sensed property of each article being conveyed, e.g. weight, colour, or size), the carrier 12 is deflected laterally in the appropriate direction by the action of a mechanical pusher or by magnetic means. The magnetic rails (18) comprise spaced pairs of rails (19), (19), of opposite polarity joined by longitudinally spaced magnets (20). Each carrier 12 has suspended from it, a ferromagnetic member 22 (Fig. 3, not shown), slightly spaced from the rail (18), or a roller (25) (Fig. 4, not shown) which contacts the rail (18).

Blocks 58, 59 may be secured to plate 42 interiorly of the inner diameter of ring 12 to limit the movement of the lower platen towards the upper platen and thus control the exact ultimate thickness of the clutch plate. Electrically conductive single split ring winding 52 may be secured to the lower surface 54 of a block of electrically non-conductive material 50 secured to platen 46, a flat plate 56 of electrically non-conductive material being secured to the lower face of ring 52.

Title: Reforming hydrocarbons
Inventor: BATES ERIC BILLINGSLEY
IPC: C10K3/02
Filed: 1963-12-20
Abstract: A liquid or gaseous hydrocarbon having at least two carbon atoms in the molecule is catalytically steam reformed by the process of the parent Specification, additional hydrocarbon being fed to the secondary reformer in an amount comprising at least 30% by carbon atoms of the total hydrocarbon feed to the process.  The temperature of the secondary stage is 450 DEG  to 800 DEG  C. and the equivalent methane content of the product gas is from 10% upwards. The process enables higher primary reformer temperatures to be used, e.g. 680 DEG to 820 DEG  C.  The additional steam required may be supplied by injection between the two reformers, or the primary reformer may be operated at a steam ratio of 7 or higher.  The secondary hydrocarbon feed, which may be the same as the first, preferably constitutes 40% to 80% of the total hydrocarbon feed to the process.  Three specific examples are described, and the catalyst in both reformers may be nickel - magnesia - china clay - aluminous cement as described in Specification 1,003,702.

Abstract: 1,020,328. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. Dec. 11, 1964, No. 50522/64. Heading H1K. In a method of making a semi-conductor device a semi-conductor body is etched to remove surface contamination, and subsequently lifetime reducing impurity is applied to the surface of the body and diffused into the body. The semi-conductor body must be protected from the action of light between these two steps because the action of light gives rise to surface conditions which inhibit the introduction of lifetime reducing impurities. Resultant devices would have random variations in their switching properties. In the embodiment described silicon slices containing partially formed planar transistors are individually subjected to the following treatment which was carried out in subdued lighting. Each slice is cleaned in boiling concentrated sulphuric acid, washed in de-ionized water, etched in aqueous ammonium bifluoride to remove any oxide film, washed with de-ionized water, and blown dry with an air jet. (At this stage the slices may be stored in the dark in water or in a solution containing free hydrofluoric acid.) Still in subdued lighting the slices are loaded in a vacuum evaporator and gold deposited on one surface of each of the slices and diffused in. A similar treatment may be given to germanium devices but an alternative oxide-removing etchant to aqueous ammonium bifluoride may be needed.
