Title: Imaging process
IPC: G03G17/10
Filed: 1968-04-30
Abstract: 1,223,357. Electro-photographic processes. XEROX CORP. April 30, 1968 [May 1, 1967], No.20429/68. Heading G2H. In an electro-photographic method, an imaging plate, comprising a substrate overlaid with a solvent softenable layer containing a homogeneous dispersion of photo-sensitive particles, has a latent electrostatic image of one polarity formed thereon, the plate is then charged uniformly with an opposite polarity and developed in a liquid or vapour solvent or by heat whereby the softenable layer is softened or dissolved and photo-sensitive particles adhere to the substrate in a negative image configuration. The latent image may be formed by uniform charging e.g. with a corona discharger, and imagewise exposure of the softenable layer, or the softenable layer and substrate may be oppositely charged with corona dischargers. If the substrate is non-conducting charging is carried out with the substrate contacting an earthed conductive plate, which may be kept in contact with the substrate during development, or stripped therefrom prior to development. Suitable substrate materials are metals e.g. gold or silver or conductively coated insulators e.g. aluminized plastics. The softenable layer may be, for example a rosin ester, an alkyd or silicone resin, a polyolefin or a polystyrene. The photo-sensitive particles may be inorganic e.g. selenium or organic, e.g. a dye pigment. The solvent for the softenable layer may be e.g. xylene, ethylether, benzene, tolvene, and must be electrically insulating and chosen so as not to dissolve the substrate and photo-sensitive material. In another embodiment, non photo-sensitive particles e.g. carbon black, are used and charging is accomplished via a mask stencil or by using a shaped electrode. In another embodiment additional steps of charging with opposite polarity and uniform exposure to activating radiation are included.

Further Al+1.2Si+0.4Ti plus or minus a figure not greater than 1.2=0.31 times the sum Ni+ 1/2 Co+ 1/2 Cu. In these relationships the chemical symbols represent the percentages by weight of the elements in the alloys.  In a modification the Ni content is 20.0-26.0 per cent, the Co content does not exceed that of Ni and Ti may then be omitted or be less than 1.0 per cent.  Up to 2.0 per cent in all of one or more of C, Mn, P, S, Cr, V, Ta, Nb, Zr, Ce, Ca, Sb, Zn and Sn may also be included.  In making the alloy Si may be introduced as a readily powdered alloy of Si with one or more of Fe, Co, Ni, Cu or Al or alternatively as a ferro-titanium containing Si with or without Al. The alloy may be subjected to a magnetic field of over 1,000 Oersted during cooling from above the Curie point to about 180 DEG C below it.  The magnets may be subjected one or more times to a two-stage anneal below 700 DEG C after treatment in the magnetic field or after cooling from about 1200 DEG C without application of a magnetic field.  Thus in an example the annealing treatment was one to two hours at 650 DEG C followed by three to eight hours at 540 DEG C. The alloys may be mechanically reduced and compressed with a binding agent or a proportion of the crushed material may be introduced in the manufacture of high grade magnetic material.

Abstract: 251,501. Tennant, W. J., (Lockwood, L. V.). Aug. 20, 1925. Blowing; forming screw-necked bottles. - Relates to mechanism for forming a screw thread in the mouth of a parison as it is being formed in a bottle-blowing machine. The mechanism is shown applied to a rotary-table turnover machine in which each blank mould 3 has associated with it a mandrel E having a threaded tip. The shank 10 of the mandrel is threaded and works through a nut 5 carried by the mould. Thus by turning the shank 10, the mandrel may be screwed into or out of the ring mould 3<a>. In accordance with the present invention, the lower end of each mandrel shank 10 is formed with a pinion or collar E<1> which has its underside provided with clutch lugs 25. These lugs are adapted to engage a clutch member F<1> which is carried at the upper end of a rod 12. The rod is raised or lowered by a pneumatic cylinder 28, and it is rotated by a shaft 17 through the medium of gear wheels 15. In operation, a shaft 12 is raised by a cylinder 28, and the rotation of the shaft screws the mandrel 12 into the ring mould. After the mould is charged with metal it is carried by the rotation of the machine to another station where the mandrel is screwed out of the ring mould by another mechanism similar to that shown, thus leaving the mouth of the parison formed with an internal screw. The unscrewing of the mandrel is started, however, while the mould is travelling between the two stations by a toothed segment which engages the pinion El.
