Title: Method of employing encapsulated substances in information reproduction
IPC: B44C1/17
Filed: 1974-07-08
Abstract: 1480642 Developing latent images on pressuresensitive papers MOORE BUSINESS FORMS Inc 8 July 1974 [9 July 1973 14 Jan 1974] 30252/74 Heading B6C A method of making patterns using substances contained in rupturable microcapsules comprises contacting two surfaces, at least one of which bears an encapsulated substance in a coating, applying pressure imagewise to the surfaces to rupture the microcapsules, separating the two surfaces, and applying a particulate developer to the releaser substance on either or both surfaces. Preferably the two surfaces have the same microcapsular coatings so that a positive and negative pattern can be produced simultaneously. The encapsulated substance is normally an adhesive or a solvent for the developer which can be fixed using heat. By selection of suitable developers, the method may produce lithographic or hectographic masters; the developed images have sufficient contrast to be used in OCR equipment or with magnetic readers. In an alternative embodiment, where the the surface is conductive, and the developer is an insulating powder the product is suitable for use as an electrographic master.

Title: Improvements in electrocopying apparatus
IPC: G03G17/02
Filed: 1958-09-24
Abstract: 907,575. Photographic apparatus; electrolytic development. MINNESOTA MINING AND MANUFACTURING CO. Sept. 24, 1958 [Sept. 25, 1957], No. 30519/58. Classes 98 (1) and 98 (2). In apparatus for exposing a photo-conductive sheet material, the exposed image area is developed by electrolysis of a developer solution at the photo-conductive surface as the sheet is advanced to bring a fresh section into the exposure position. The sheet material preferably consists of a thin aluminium foil backed by paper and coated on the exposed side with a photo-conductive composition of zinc oxide in a styrene butadiene binder. As shown, in a micro-film reader and copier, the foil is electrically connected to spindle 31 of supply roll 29 and the circuit to batteries 38 is completed through sponge-like developer applicator pad 35, developer tank 37, switch 20, variable resistor 23 and ammeter 22. Thus, when switch 20 is closed the developer between pad 35 and the photo-conductive surface is electrolysed. Micro-film 16 is wound between spools 17 and 18 and its image is formed on ground-glass viewing screen by lens 15 and mirror 25. Exposure is effected by momentarily moving the mirror to the full-line position and returning it to the viewing position. Immediately thereafter, switch 20 is closed and the material 30 is withdrawn at a constant speed through slot 33. Contact with pad 35 is assured by spring strip 36 which light-traps slot 33. In another form (Fig. 4, not shown) the material is fed out of the slot from between a pair of developing rollers. Rollers surfaced with formaldehyde hardened gelatine plasticized with glycerol or other humectant may hold sufficient electrolyte or moisture for tank 37 to be omitted. However, when the rollers are made of such materials as compressible rubber, metal or ceramic, the lower roller dips into a tank 37. Alternatively, the developer may be brought into contact with sheet 30 by a brush arrangement (Fig. 5, not shown) dipping into the tank and the sheet advanced by sprockets engaging marginal perforations in the material. Unperforated material may be advanced by a spiked sprocket which pierces the material and, since the spikes make electrical contact with the aluminium foil, the electrical connection may be made to the spiked sprocket instead of to spindle 31. Preferably, development is carried out by electrolysis of an aqueous solution of cadmium nitrate, tartar emetic and silver nitrate. Development may be effected by electrodeposition from solutions copper or nickel ions or by chemical action which follows the deposition of a non-metallic ion. Nickel may be deposited to produce a lithographic printing plate directly. In another arrangement (Fig. 6, not shown) material which recovers its electrical resistance rapidly after exposure is immersed in a tank of developer which is electrolysed during exposure through a ring-shaped electrode.

Abstract: 483,845. Claw clutches ; variablespeed gearing ; universal joints. HARDY, W. G. Nov. 10, 1936, No. 30717. [Class 80 (ii)] The slidable sleeve K<1> of a claw clutch, used in a variable-speed gear, is connected to a ring K<3>, which is splined on the shaft J<2>, by means of a universal joint comprising an intermediate ring K<5> which is engaged by a pair of rectangular trunnions K<4> on the ring K<3> and which has a pair of rectangular trunnions K<6> arranged at right-angles to the trunnions K<4> and engaging the sleeve K<1>. The trunnions engage in openended slots and are retained by spring rings L, L<1>. When the clutch is disengaged, a portion O of the sleeve K<1>, adjacent the claws, is supported on the shaft, but when the clutch is engaged the portion O is clear of a reduced portion of the shaft so that the sleeve can tilt so as to obviate any tendency of the clutch to disengage. The sleeve K<1> is moved by a grooved collar N<2> secured to cylindrical plugs N' housed in round holes in the sleeve, the plugs being held against rotation by pins N<3> engaging grooves N<4> in the holes. The plugs N<1> also provide detent surfaces controlling a sleeve M<1> carrying a synchronizing friction cone. In a modification, the ring K<3> is dispensed with, the ring K<5> being engaged by a pair of oppositelydisposed splines on the shaft, these splines acting as trunnions. The Provisional Specification describes also a double-ended claw sleeve. When the sleeve is in neutral position, portions thereof adjacent the claws are supported on shoulders on the shaft, but, when either clutch is engaged, these portions move off the shoulders. The universal joint is arranged centrally, and the trunnions which engage the sleeve pass also through the sleeve carrying the synchronizing cones, provide the detent surfaces therefor, and carry the grooved operating collar.

Title: Improvements in or relating to surface coating compositions containing epoxy resins
Inventor: PYE CHARLES ROSSALL
IPC: C08G18/58
Filed: 1953-11-09
Abstract: A coating composition is a solution of an epoxy resin with a masked tri-isocyanate or masked tri-isothiocyanate.  Copper or aluminium wire may be coated with such compositions followed by stoving at 150 DEG  C. or above to release the isocyanate or isothiocyanate for curing the epoxy resin.  Other resins, e.g. rosin, amino-formaldehyde or phenol-formaldehyde resins or polyesters may be added to the compositions.  Suitable masking agents for the iso- or isothiocyanate are phenols, e.g. m-cresol, mercaptans, amines, hydrazines, malonic ester, acetoacetic ester or butanol.  The masking agent may also be a solvent for the epoxy resin.  In a typical example a resinous tri-isocyanate obtained from 3 mols. of toluene di-isocyanate with 1 mol. of trimethylol propane is dissolved in mixed ethyl and butyl acetates and mixed with a solution in the same solvents of isobutyl alcohol and a resin sold under the Registered Trade Mark of "Epikote".  In other examples m-cresol replaces the iso-butyl alcohol, xylol and n-butanol are added as solvents, the m-cresol is reacted with the triisocyanate before admixture with the epoxy resin solution, rosin is added to the composition, and "Desmodur AP" (Registered Trade Mark) is used as a ready masked tri-isocyanate. Specification 747,607 is referred to.
