Title: A method of reversing the image in xerography

Abstract: 897,903. Electrophotographic processes. AUSTRALIA, COMMONWEALTH OF. Dec. 30, 1958 [Jan. 13, 1958], No. 42031/58. Drawings to Specification. Class 98(2). A xerographic photoconducting surface is charged and exposed and the electrostatic charge pattern is reversed by re-charging after development with a substance which, on deposition, is sufficiently electrically conductive to discharge and partially or completely to prevent the parts which it covers from being re-charged on re-performing the charging operation. The surface is there after redeveloped, preferably with a dark pigment dispersed in an insulating liquid, to complete a reversal development by depositing developer on parts originally discharged by exposure. Preferably, the conductive developer substance is removed after re-development. Metallic powders such as aluminium or bronze powders can be used as conductive developer substances which prevent the surface which they cover from accepting any electrical charge. The powders are dispersed in insulating liquids. After re-development of the surface with a pigment or dye dispersed in an insulating liquid, the powder may be removed by rubbing, adhesive transfer or solution in nitric acid. Water soluble dyes such as Tartrazine dispersed in insulating liquids function as developer substances in the same way as metallic powders and may subsequently be removed by solution in water. The reversed electrostatic charge pattern is re-developed with a developer such as a resin treated phthalocyanine blue, carbon black, organic red pigment or lead chromate dispersed in an insulating liquid. The conductive developer layer can permit selective re-charging of the surface which it covers and thus provide for continuous tone reproduction. A conductive developer substance consisting of a mixture of zinc and barium white or metallic naphthenates and titanium dioxide dispersed in insulating liquids form such a layer.

[Also in Division G6] An energy absorbing device for damping the fall of articles such as fuel elements in a vertical duct in a nuclear reactor comprises a first cylinder 26 arranged to receive the impact of the article and to be plastically deformed in order to absorb its energy and a second member 16 supporting the first member 26 and extending below it. The second member 16 has a weaker portion 22 arranged to yield in the event of a severe impact so that the lower end of member 16 is arranged to contact a fixed structure and still provide support for the first member 26. As described, pressure tubes 6 are attached to the calandria bottom 4 of a heavy water-moderated nuclear reactor which is cooled by downward flow of carbon dioxide. A guide 8, comprising two thin metal sleeves separated by thermal insulation, restricts the heating of the heavy water. The deformable tube 26 is crimped to the outer tube 16 and supports a thrust member 30, a dummy bottom fuel element 34 and a series of fuel elements (not shown). The thrust member 30 is arranged to collect debris (e.g. graphite fragments). In the event of a comparatively small impact on member 30, the breaking portion 22 remains intact, the energy being absorbed by deformation of member 26. In the case of a larger impact, portion 22 yields so that the lower end of member 16 is supported by reflective shielding 20 whilst member 26 absorbs the energy by deformation. The thinner portion 22 may be replaced by fastenings, soldered or screwed to the upper and lower portions of member 16. and arranged to break at a calibrated load.

The type hammers 24 are electromagnetically operated/ spring returned (Fig. 2). In Fig. 1, type levers 11a are disposed to be advanced as they pass selected print positions by the actuating means 31, which comprises a series of slides 32 which when advanced engage different ones of the type levers 11a as they pass by, and cam them into an advanced position. A plurality of electromagnets 35 have a common hold winding 36 linking the electromagnets 35 for holding the slides 32 in the retracted position against the bias of springs 34. Individual buck windings 37 are selectively energized to oppose the hold winding 36 so that selected slides 32 are released and advanced by springs 34. Each buck winding 37 is wired in parallel with the electromagnet winding (27, Fig. 3) of the associated hammer 24. Instead of having a hammer 24 for each character position, each hammer may cover two or more character positions.
