Title: Colour photography
Inventor: NEALE DENIS MANKTELOW
IPC: G03C7/18
Filed: 1960-02-15
Abstract: 907,730. Colour photography. ILFORD Ltd. Jan. 27, 1961 [Feb. 15, 1960], No. 5320/60. Class 98 (2). Colour cast in printing is corrected by forming an intermediate record of an original such as a negative on a first area of print material and printing the original again with the intermediate record in the path of the light on to a second area of print material so that the printing light at each part of the second area is modulated by the integrated colour of the intermediate record. Thus if an original negative has an overall blue cast the intermediate will exhibit an overall yellow cast which acts as a blue-absorbing filter in printing a final positive. The intermediate need not be of the same size as the final positive and the latter may be an enlargement as on a paper base. Specifications 658,329 and 660,099 are referred to.

Title: Method and apparatus for selectively transferring electrical oscillatory energy
IPC: H01F19/00
Filed: 1922-02-23
Abstract: 198,052. Fairweather, H. G. C., (Dubi lier, W.). Feb. 23, 1922. Coupling aerial and detector circuits; multiplex signalling; thermionic amplifiers and detectors.-Electric oscillations extending over a relatively broad band of frequencies, corresponding to the envelope-curve D, Fig. 1, are transferred from one circuit to' another with a combined effeciency corresponding to that of the tuned resonance curve C by the use of a series of tuned circuits LC, &c. as shown in Fig. 1<a>. The resonant frequency of each of the circuits LC. L<1>C<1>, L<2>C<2> is different from that of the others, and the values of inductance and capacity are so chosen that frequencies near the resonant point of one circuit are by-passed to or from that circuit through the other circuits. As shown in Fig. 3, tuned circuits 23, 24, 25, and 26, 27, 28 in the output circuits of amplifiers 1 and 2 respectively are coupled to correspondingly tuned circuits 29, 30, 31 and 32, 33, 34 in the input circuits of the amplifiers 2 and 3. The circuits 23 - - 28 may be replaced by ind.uct. ances or by the primaries of iron or air cored transformers, shunted or not by tuning-condensers. Or the input and output circuits of successive valves may be linked by one series of tuned circuits forming an auto-tnmsformer coupling. As applied to a wireless receiving set, Fig. 5, separately-tuned circuits 41, 42, 43 coupled to the aerial 44<1> are unilaterally ,connected to the grid 6 of the ampli- '6er 1, the output circuit of which is linked through an inductance 41 to a similar series of tuned oircuits 45 - - 47 of a second amplifier 2, this, in turn, being coupled to a detector 3. In its simple form, Fig. 6, tuned circuits 56, 57 are associated with an otherwise aperiodic secondary circuit containing a detector D and telephones R, the imaginary condenser 60 representing the inherent combined capacity of the coils. The secondary is thereby rendered sharply selective for frequencies lying within the resonance range cf the circuits 56, 57.

Patent GB-1099991-A (GB)
Title: Improvements in and relating to process for the manufacture of graft copolymers
IPC: C08F291/18
Filed: 1965-02-08
Abstract: In a process for the manufacture of graft-copolymers, a monomer containing a vinyl or vinylidene group is graft-polymerized on to a trunk polymer or copolymer comprising units of a monomer containing at least one halogen atom that is activated by an ester or a phenyl group, in the presence of a free radical polymerization catalyst and under the action of ultra-violet light or high energy ionizing radiation.  The trunk polymer may be derived from an ester of a -bromoacrylic acid, a vinyl ester of a bromo- or dibrom-butyric acid or bromoacetic acid, p-bromostyrene or diethyl bromomaleate or bromofumarate, optionally together with vinyl, acrylic, methacrylic or maleic esters, vinyl aromatic compounds, acrylonitrile, vinyl chloride, vinylidene chloride or butadiene.  The grafted monomer may comprise a styrene derivative, a vinyl aromatic compound, a vinyl ester or ether, or vinylidene chloride; and may comprise a monomer of similar structure to a comonomer of the trunk copolymer. Alternatively the trunk polymer may be obtained by transfer reaction between a halogenated hydrocarbon and the growing chain in a free radical polymerization.  The graft monomers may be prepolymerized by bulk, emulsion, suspension or solution polymerization prior to grafting and the graft monomer or prepolymer may be grafted in bulk, emulsion, suspension or solution.  The heat distortion of polyvinyl chloride may be improved by grafting methyl methacrylate or cyclohexyl acrylate on a vinyl chloride copolymer, and the impact strength of polystyrene can be improved by grafting styrene on a styrene/vinyl naphthalene/ p-bromostyrene copolymer. Examples describe the grafting of (1) vinyl chloride on a butyl acrylate/butyl a  - bromoacrylate / vinylidene chloride copolymer, (2) methyl methacrylate on a vinyl chloride/allyl p-bromobenzoate copolymer, (3) styrene on a styrene/vinyl naphthalene/ p-bromostyrene copolymer, and vinyl chloride on a vinyl chloride/butyl acrylate/allyl a ,b -dibromobutyrate.
Patent GB-331201-A (GB)
Title: Improvements in or relating to processes for surfacing articles with films comprising pigments, varnishes, glazes, enamels, lacquers or the like
IPC: C04B41/81
Filed: 1929-02-19
Abstract: 331,201. Brown, G. M. and Wyse, H. T. Feb. 19, 1929. Divided on 332,190, [Class 140, Waterproof &c. fabrics]. Coating with liquid &c. materials.-In applying a surface coating to an article the coating material, which may comprise varnishes, pigments, glazes, enamels, lacquers, &c., is deposited ' on a flotation medium as a film of substantially greater area than the surface to be coated, one end of the article is then brought into contact with the film leaving marginal portions thereof extending some way beyond the article, and relative movement between the article and the flotation medium is effected at right angles to the plane of the film so as to cause substantially complete immersion of the article and to draw the film away from the surface of and through the medium into enveloping contact with the whole surface of the article. The article may be lowered into the flotation medium or may be held stationary above the medium and the level of the latter raised by upward movement of the trough containing it or by forcing more liquid into the trough. The coating materials used include a pigment in a vehicle such as boiled linseed oil to which a volatile solvent or other thinning agent may be added, compositions, e.g. a cellulosic solution, giving a glazed or enamelled surface, cellulose lacquers diluted with thinners, printers' ink diluted with petrol, Reeves' waterproof poster colours diluted with petrol, and ox-gall and water as used in the known hand process for making marbled papers. Monochrome or variegated colour films may be used and irregular patterns may be produced by stirring the film, by depositing the colour by spraying, by spraying ox-gall, water or other liquids on the colour, or by giving an irregular movement to the article being coated. The surface of the article to be coated may be treated with a resist, such as a sugar solution, which will prevent deposition of the film, or with an imperfect resist which will modify the amount of film applied, by means of which ornamental designs may readily be obtained. In the example given, the flotation medium 2, e.g. water or an aqueous solution of Caragheen moss, is filled into a stepped trough 1 and a coating film 3 deposited thereon. A vase 4 of porcelain &c. is then gradually lowered into the trough, one edge of the base being first brought into contact with the film and the contact gradually extended to prevent formation of an air bell. Where a large dipping trough is used it may be subdivided into pools by a frame or frames floating on the liquid, and films of different colours may be formed in the separate pools. With some colours and flotation media as many as four articles may be coated from a single film. Specifications 4219/82, 7145/84, 14465/99, 245,209; and 262,601, [Class 120 (iii), Yarns &c.], are referred to.

Title: Improvements in or relating to mechanism for pointing bolt blanks and the like
IPC: B23Q7/10
Filed: 1935-02-20
Abstract: 438,641. Making blanks for bolts etc.; forging ; screwing; turning. NATIONAL MACHINERY CO., Tiffin, Ohio, U.S.A.-(Assignees of Friedman, J. H.) Feb. 20, 1935, No. 5515. Convention date, Feb. 20, 1934. [Classes 83 (ii), 83 (iii), and 83 (iv)] In apparatus for pointing bolt blanks and the like, a work holder and cutter are moved towards one another, and a pair of trackways are arranged one on each side of the work holder, means being provided for pushing the blanks along one trackway into the work holder and for ejecting the blank out of the work holder into the other trackway. The movement of the blank occurs during the separation of the work holder and cutting mechanism. As shown, a header slide 10, Fig. 1, has tools 3, 4, 5 at one end co-operating with complementary tools on a frame. At its other and rear end a roll threading die works in conjunction with a roll threading die on the frame. Wire or rod stock S is fed, sheared, and the cut-off blank transferred to a position in alignment with a beader tool 3. The blank is worked successively by the tools 3, 4 and 5, of which the last-named may be a trimming tool with a hollow bore leading into a tube 6. The tube is pivoted to the beader slide at one end and pivotally and slidably mounted adjacent the pointing mechanism 20, Fig. 4. The tube is slotted to cause the blanks to hang by their heads, which they continue to do as they pass along parallel tracks 7 leading to the pointing mechanism. The pointing mechanism comprises a work holder 31, Fig. 2, and a revolving cutter 29 towards which the work holder is moved by the action of a spring 32<a>. During this movement the jaws of the work holder are progressively tightened on the blank by engagement, with an inclined smface. The cutter 29 is revolved by means of a motor and after the completion of the pointing a cam actuated lever 33 moves a tube 32 longitudinally against the action of the spring 32<a> to withdraw the work holder from operative position. A pair of co-ordinated pushers 27, 28 serve to feed the terminal blanks singly, the pusher 28 advancing a blank positioned by the pusher 27. The head of the blank contacts with the head of a blank in the work holder and ejects it into the feedway 71 from which it may pass by an elevator tube 40, which lifts the blanks upwardly through a tube 42. From the tube 42 the blanks enter a downwardly inclined tube or track leading to roll threading dies described in Specification 436,179.
