Title: Improvements in aluminium paints
Inventor: BIRD CHARLES ERNEST
IPC: C09D5/10
Filed: 1955-01-14
Abstract: An aluminium paint is produced by abrading a metal powder consisting wholly or mainly of aluminium free from anti-pyrophoric lubricants until any insulating film around the particles is broken down sufficiently to allow electrical conductivity in the dried paint film, the abrading being carried out under conditions such that an insulating film is not re-established, and incorporating the powder in a paint medium.  Preferably, the abrading comprises grinding in a ball mill or the like in the presence of a liquid which may be either the paint vehicle, or an organic liquid miscible therewith.  The powder may contain small amounts of zinc, magnesium, cadmium or silicon.  Examples are given of a 95 per cent aluminium, 5 per cent zinc powder abraded in the presence of xylene, then made into a paint with either an epoxy resin or polystyrene; a 72.5 per cent aluminium, 25 per cent zinc, 2.5 per cent lead powder similarly abraded and made into a paint with an epoxy resin; and a 80 per cent aluminium, 20 per cent zinc powder similarly abraded and made into a paint with a solution of polystyrene.  The epoxy resin may be either of the two types in which an amide group or an amine group brings about the hardening, and suitable hardeners are included in the compositions. Optional additives are graphite, zinc oxide, or magnesium oxide.ALSO:A metallic paint comprises a metal powder, mainly aluminium, and a cold-setting synthetic resin medium, such as an epoxy resin with an amide or amine type hardener, polyester resins and plasticized polystyrene.  The aluminium which may contain zinc, cadmium or lead, or be an alloy with zinc, magnesium, silicon and/or cadmium, and is free of lubricant, is abraded before use by grinding in the medium or in a miscible solvent such as xylene, solvent naphtha, cyclohexanol, methyl iso-butyl ketone, butanol, isopropanol, toluene, diacetone alcohol and glycol monoethyl ether.  Graphite, magnesium or zinc oxides may also be present.

Title: Improvements in isocyanate-containing adhesives
Inventor: GABRIS TIBOR
IPC: C09J175/02
Filed: 1963-01-11
Abstract: An adhesive composition comprises a linear or branched polyamide containing primary or secondary amino groups, and having an amine number of less than 60, in intimate admixture with a blocked di- or polyisocyanate, the melting point of the polyamide being below the activation temperature of the blocked di- or polyisocyanate, and the blocked di- or polyisocyanate being present in an amount of 5 to 25% by weight of the total composition. Suitable polyamides are those made from dicarboxylic acids and diprimary amines containing one or more secondary groups in the chain or from diprimary amines which may contain secondary amino groups and polymerized unsaturated fatty acids. Suitable blocking agents are phenols and alcohols and also b -ketonic compounds.  Blocked isocyanatos specified are phenol blocked 4,41-diphenylmethane diisocyanate, and a phenol blocked prepolymer derived from tolylene diisocyanate and trimethylol propane.  In Example (1) phenol blocked 4,41-diphenylmethane diisocyanate was added to a polyamide derived from ethylene diamine and the methyl ester of polymerized unsaturated fatty acid (dimerginic acid) to form a composition which was stable on storage.  The compositions may be heated above the activation temperature of the blocked isocyanate so that the adhesive cures in situ.

Title: Improvements in electrostatic printing
IPC: G03G15/22
Filed: 1956-01-16
Abstract: 797,024. Electrophotographic processes. GENERAL DYNAMICS CORPORATION. Jan. 16. 1956 [Jan. 26, 1955], No. 1420/56. Class 98(2) A visual reproduction of an object is made by contacting the surface of a photoconductive layer on a conductive backing with the surface of an electrically semiconductive layer on a conductive backing, projecting a light image corresponding to the object on to the photoconductive layer either immediately before, during or after its contact with the semiconductive layer, applying a potential difference between the conductive backing layers, and then developing the latent image formed, either on the photoconductive layer or on an insulating layer to which it has been transferred from the photoconductive layer. The method is distinguished from that of Specification 755,486 in that the electrostatic latent image is formed initially on the photoconductive layer itself. The photoconductive element and the semiconductive element may be in the form of cylinders or plain surfaces. Fig. 1 shows a cylinder 6 comprising a transparent cylinder 8, a transparent conducting layer 9 and a photoconductive layer 10 in rolling -contact with a cylinder 7 comprising a metal core 11 coated with, semiconductor material 12 such as a semiconducting rubber. A battery 15 maintains a potential difference between, the conductors 9 and 11. A transparent original 14 is placed inside the cylinder 8 and illuminated by a lamp 13. A shield 26, which remains stationary when the drum rotates, is positioned to restrict the illumination to a narrow strip of layer 10 at the time of contact between he cylinders. The layer 10 also may be exposed before or after the line of contact with the semiconductive surface, and in either case the image may be projected on the layer 10 from a position external to the drum. In any case, an electrostatic latent image is formed on photoconductive layer 10 as the cylinders rotate, and is developed thereon at 22, for example with carbon black. The carbon is preferably suspended in an insulating liquid and applied by means of a roller. At 16 the powder image is transferred to paper strip 17 and the surface 10 cleaned at 18. In a modification, the drum 7 comprises a central metal core, a resilient rubber layer, then a conducting layer (which is connected to the battery) and finally the semi-conductive layer 12. In a further modification, the latent image is not developed on photoconductive layer 10, but is transferred to another cylinder comprising a metal core and insulating coating and situated on the opposite side of cylinder 6 to cylinder 7. This insulating cylinder is provided with developer means and means to transfer the powder image to a paper strip as described above. In further modifications, firstly the cylinder 6, and secondly both cylinders 6 and 7 are replaced by similarly constructed flat plates. Specifications 672,767, 679,533 and U.S.A. Specifications 2,221,776, 2,277,013 and 2,551,582 are referred to.

Title: Improvements in or relating to processes and devices for screening and filtering moist particulate materials
IPC: B07B1/00
Filed: 1958-01-15
Abstract: 838,164. Filters. RHEWUM RHEINISCHE WERKZEUGUND METALLWARENFABRIK G.m.b.H. Jan. 15, 1958 [April 4, 1957 ; June 11, 1957], No. 1432/58. Class 46. Mixture to be screened is fed at 6, Fig. 1, to a screening web 1 secured at 2 immovably to a frame 3 and attached at 4 to the oscillating armature of an electromagnet 5. whereby longitudinal oscillations are imparted to the end 4. From the end 4 to a point 13, Fig. 2, the oscillations are mainly longitudinal, but from 13 to 14 they are mainly transverse. Solids are collected by an inclined shoot 10, Fig. 1, and liquid by a funnel 8 and hose 9. The supporting members 3, 4 may be parallel and coplanar and inclined to the horizontal (transversely to the web, Fig. 3 (not shown) ; or co-planar and horizontal but not parallel, Fig. 5 (not shown). The supporting members may be so arranged that the ends of the web are not equally inclined to the horizontal. Both supporting members may be oscillated, Fig. 8- (not shown). One supporting member may be higher than the other, Fig. 9 (not shown); or both may be twisted with respect to the centre axis of the web at equal angles but in opposite directions, Fig. 10. The longitudinal oscillations tend to transport the solids towards one (or both) ends of the web depending upon whether one or both ends are oscillated. Where the supporting members are horizontal and parallel the solids are discharged over both sides ; where both ends are oscillated and the web is twisted and the solids have different specific gravities, fractions differing in specific gravity are discharged in opposite directions. In all other examples the solids are discharged over one side only.
