Title: Improvements in processes for moulding decorative patterns, motifs or symbols from plastic materials
IPC: G09F7/16
Filed: 1946-07-18
Abstract: 614,603. Moulding decorative patterns, symbols, &c. CHADWICK, A., and GAIR, S. July 18, 1946. Nos. 21459/46, 33396/46 and 9776/47. [Class 87 (ii)] [Also in Group XV] Decorative patterns, motifs or symbols are moulded from a plastic material, such as polyvinyl chloride paste, by applying the material to an enclosed space 1a, of the shape of the desired pattern, in a plate 1 pivoted to a frame 3, rolling or pressing the material into the space 1a, swing- ing back the plate 1 to leave the moulded material 4, Fig. 3, on a base plate 2, spraying the material 4 with metal dust or with dyed flock, then polymerizing the material by heat, and after cooling, removing the moulded article 4 from the plate 2. The pattern may be moulded on a sheet of textile material or to form a table mat, on a previously moulded and polymerized pattern. The sheet or moulded pattern being placed on the base plate 2 before moulding. An inlaid pattern may be formed by moulding and polymerizing a pattern, and then pressing it in to a layer of moulded material, while in paste form, on a base plate, spraying the material with colouring matter, which sticks to the paste but not to the polymerized pattern, and then polymerizing the whole. When parts of the moulding plate are completely surrounded by a moulding space, e.g. the centre of a letter 0, these parts may be soldered to the underside of gauze held in a frame. The parts of the moulding plate may be made of cardboard or paper. To prevent the moulded material being lifted with the moulding plate, due to a suction effect, the base plate may have a series of small holes in it. According to the first Provisional Specification the base plate may be made of metal or glass and may have a raised or indented surface ; and the top surface of the moulded material may be grained by the use of a roller or a second layer may be built up on the material by applying a perforated metal sheet to the moulding plate. Parts of the moulding plate, e.g. the centre of a letter 0, may be held in position by pegs fixed to the base plate and these parts may be removed by a magnet. Guides may be provided to ensure that the moulding plate is lifted vertically from the base plate.

Title: Improvements in or relating to aircraft with rotative wings
IPC: B64C27/02
Filed: 1925-11-24
Abstract: 264,753. La Cierva, J. de. Nov. 24, 1925. Screw and like propellers.-In freely-rotative wing-systems for aircraft of the kind described in Specification 196,594, a flapping movement of the wing is produced due to the difference in the speed of the advancing and retreating wings relatively to the air stream, which results in the wings assuming widely varying incidence in different angular positions. According to the invention, this range, is diminished by so hinging each wing at its root that its incidence automatically decreases as the wing swings upwards and increases as it descends without altering the symmetrical relationship of the wings about the axis of rotation. In the construction described the axis of the hinge joint E of each wing C viewed in plan as in Fig. 1, is set at an inclination to the longitudinal axis of symmetry of the wing such that. the smaller angle n is forwardly disposed with regard to the direction of rotation. As this alone causes the wings in flapping to change their relative position in plan, the hinge joints are also inclined viewed in elevation as in Fig. 3, to restore the swinging movement of the longitudinal axis of the wings to a plane containing or parallel to the axis of the shaft A on which the wing-supporting member B rotates. In the construction shown, the path of movement of the longitudinal axis of the wing is parallel to the axis of the shaft A but by forwardly displacing the bearings D coincidence may be obtained.

Filed: 1929-07-16
Abstract: 315,715. Ellis, R. E., (General-Direktion der Oesterr. Tabak-Regie). July 1.6, 1929. [A Specification was laid open to inspection under Sect. 91 of the Acts, July 17, 1929] Tobacco; smoking-mixtures. - Tobacco or a mixture of tobaccos is denicotined by a treatment not involving lixiviation and is then treated with an aromatic flavouring not derived from the raw tobacco. The nicotine may be extracted by heating above 150‹ C. in a rapid current of pre-heated air, gas, or dry steam, as described in Specification 290,204. In one example, a mixture of Virginia, Maryland, Burley, Java, and Latakia leaves is denicotined by the method described in Specification 290,204 and is steamed for a short time and the stems may be removed. The leaf is then sprinkled with an alcoholic solution of suitable essential oil, such as geranium oil. In a second example, a mixture of Virginia and oriental tobacco, after being denicotined, stripped and cut, is sprinkled with the aromatic flavouring. The Specification as open to inspection under Sect. 91 (3) (a) states also that the denicotining may be effected by exposing to heat in a closed heat-insulated vessel, the air in the vessel being continually cooled and the temperature gradually increased from 150‹ to 185‹ C., the resulting vapours being condensed and removed. In the first example referred to, the tobacco, after denicoting, steaming, and stripping, was saturated with a solution of salt, saltpetre, and sugar containing an extract of dried plums, raisins and carob, and then dried, steamed, and cut, and sprinkled with an alcoholic extract of ground violet root, folia liatris, cloves, and musk. Other ingredients which could be used include dried pears, tonka beans, dried currants, and scenting materials such as clover flowers or cassia In the second example, the tobacco, after being denicotined, stripped, and cut, was sprinkled with a mixture of honey, " Glypho," and water and sprayed with an alcoholic extract of clover flowers and folia liatris containing a little geranium oil. This subject-matter does not appear in the Specification as accepted.

Abstract: 336,659. Dunlop Rubber Co., Ltd., Twiss, D. F., Round, A. A., and Madge, E. W. July 18, 1929. Later, coagulating.-Rubber is deposited from an aqueous dispersion thereof by connecting an alternating current supply to a pair of electrodes immersed therein, the electrodes being of dissimilar materials which are such as to effect considerable rectification of the alternating Current. One electrode is preferably of aluminium or tantalum: the other, which serves as anode for the rectified current, may be of zinc or carbon. The rubber is normally deposited on the anode or on a porous mould surrounding .t. The dispersion may, however, be treated according to Specifications 301,100, 331,563 and 334,581 in which case the deposition takes place in the neighbourhood of the aluminium or tantalum electrode. The liquid in contact with the rectifying electrode preferably contains a suitable electrolyte such as an alkali metal phosphate cr borate, e.g. ammonium or potassium phosphate or sodium borate or borax; the electrolyte may be contained in a gypsum or unglazed earthenware vessel surrounding the electrode. In deposition from latex, development of gas at the deposition base may be prevented by preliminary treatment of the latex and employment of suitable metal or alloy bases according to Specification 257,885. The aqueous dispersions treated may be natural or artificial dispersions of rubber, gutta-percha, balata or similar vegetable resins or artificial dispersions of coagulated rubber, vulcanized rubber or rubber reclaim and may contain the usual additions. Compounded and concentrated latex compositions prepared according to Specification 290,313 are suitable for treatment according to the invention.

Title: A process and apparatus for heating and fusing a vitreous material
IPC: H05B6/36
Filed: 1960-06-27
Abstract: 950,742. Electric heating of vitreous material. S.A. DES ETABLISSEMENTS PARRAMANTOIS ET CIE. June 27, 1960 [June 25, 1959; June 9, 1960], No. 22475/60. Heading H5H. A process for heating and fusing a vitreous material comprises making the material the dielectric of a capacitor, supplying the electrodes of the capacitor with a high frequency voltage so as to raise the temperature of the material by the dielectric bosses occurring therein and using the electrodes to pass an electric current through the material, when the latter has been raised to a temperature at which it is electrically conductive, to heat the material by the Joule effect. The apparatus shown for carrying out the process comprises a crucible 1 of platinum or a platinum alloy thermally insulated from a casing 4, e.g. of porcelain, steatite or fused quartz by material 5, and resting on a refractory base 2 which rests on an earthed metal plate 3, e.g. of copper. The casing 4 is surrounded by an induction coil 7. Alternatively, the casing 4 may be made of metal and the crucible heated by resistance elements. A member 8 also of platinum or a platinum alloy is supported in the crucible 1 by a rod 9. The crucible 1 and member 8 form two electrodes of a capacitor and are connected in an oscillatory circuit comprising an inductance 12 and a variable condenser 13. The Joule heating circuit comprises a high frequency choke 14 and a transformer 15, the secondary winding of which is shunted by a condenser 16. The member 8 may be adjustable in height relative to the crucible 1 or may be frusto-conical in shape (Figs. 2 and 3, not shown) to provide different degrees of heating at different heights. The top of the casing 4 may be made dome-shaped to correspond to the dome-shaped top of the crucible 1, and the induction coil 7 may be shaped so that the coupling is closer at the top of the crucible than at the bottom to make the induction heating greater at the top (Fig. 4, not shown). Alternatively, a cylindrical induction coil may be used, the lower part of which is shunted by an adjustable inductance (Figs. 5 and 6, not shown). If the crucible 1 is heated by resistance elements, the elements at the top may dissipate more power or may have a greater radiating surface than those lower down. The member 8 may also be heated by two internal resistance elements (Fig. 7, not shown) which are first connected in series. When melting commences the elements are connected in series with the vitreous material and when a certain temperature is reached, one element is shortcircuited. In a later stage the two elements are connected in parallel with each other and in series with the molten material, and in a final stage may again be connected in series. Graphs are given showing the variation of resistance and of current with time during the successive stages. The process enables fusion and refining of a vitreous mass to be carried out in one apparatus without resorting to mechanical mixing.
