Patent GB-287460-A (GB)
Title: Method of producing printing plates
IPC: G03F7/06
Filed: 1928-03-19
Abstract: 287,460. Dunlop, S., (Aktiebolaget Rapido. grafi). March 19, 1928. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 19, 1928]. Photo-mechanical printing-surfaces; screens; emulsions, preparing.-Printing surfaces are produced from gelatine films sensitized with a silver salt and treated with a chromium salt, the films before exposure, and preferably before incorporation of the chromium salt being hardened by a saturated alum bath, or by a preliminary bath of alum followed by a formalin bath. After exposure the hardening of the gelatin is modified by treatment with acid of suitable pH-concentration. In a detailed process, a silver chloride film is prepared in a particularly described manner with silver nitrate and sodium chloride. For making direct printing-plates the zinc or other support may be first prepared with an adhesive gelatin coating containing waterglass, and the edges of the film are coated with shellac. The hardened silver gelatin film is bathed in ammonium bichromate, and after exposure treated with dilute sulphuric acid. The exposed film may be subjected to further hardening before the acid treatment. The plates may then be moistened and inked up for direct printing. Stereotypes may be produced by a process of slow drying after inking, which results in a contraction of the unexposed gelatin. Alternatively a transfer may be made on to a zinc plate for etching. Large printing surfaces may be made by enlarging directly thereon. The Specification as open to inspection under Sect. 91 (3) (a) includes also a process for making screens according to which the sensitized films are exposed directly to evenly distributed or diffused light and treated with acid. This subject-matter does not appear in the Specification as accepted.

Title: Arrangement for moving the armature in electric magnetic systems
IPC: H04R11/00
Filed: 1931-03-19
Abstract: 385,290. Loud speakers. HUTH, E. F., 108, Kopenickerstrasse, Berlin. March 19, 1931, No. 8499. Convention date, April 7, 1930. Void [Published under Sect. 91 of the Acts]. [Class 40 (iv).] A loud-speaker actuating unit comprises an armature 1 surrounded by a coil 6 and carried on blade springs or levers 2, 3 pivoted at 4, 5, the armature in actuating, the diaphragm 7 being adapted to move parallel to its initial position in the gap between the magnet poles N, S. The levers 2, 3 instead of being parallel as shown may be arranged at an angle to one another, in which case, the armature during movement will assume various inclined positions. Fig. 3 shows a similar construction to that shown in Fig. 1 but employing four magnet poles obtained either by the use of two separate magnets or of a single magnet, Fig. 4 (not shown), each pole of which is provided with two projections, one being arranged above one end of the armature and the other below the other end thereof. Fig. 5 shows a further modification in which like magnet poles are positioned on the same side of the armature and the levers 2, 3 are arranged on opposite sides thereof, the extreme positions of the armature being indicated by the broken lines. In all the constructions so far described, the armature is not moved accurately in the direction of the diaphragm axis but deviates therefrom in the vertical plane upwards and downwards so that it is necessary to connect the armature with the diaphragm by elements which are only movable in the vertical plane, e.g. by a blade spring which can yield slightly only in the vertical plane. Fig. 6 shows a further construction designed so as to enable the centre of gravity S<1> of the diaphragm to move only horizontally on its axis by arranging the lever 2 to form a small angle with the armature axis whilst the lever 3 forms a large angle therewith. A construction is also described in which the diaph agm is arranged so that its axis stands perpendicular to one of the levers 2, 3.

Title: Improvements in and relating to the pyrolytic conversion of hydrocarbon oils
Filed: 1936-03-23
Abstract: <PICT:0472601/III/1> Hydrocarbon oils are converted into products of different boiling ranges by treating the oil with liquefied normally - gaseous hydrocarbon solvent to remove asphalts &c., subjecting the purified stock to mild liquid-phase cracking, separating the cracked products into vapours and a primary liquid residue, subjecting the vapours to vapour-phase cracking and separating the products into a secondary residue and vapours, distilling the primary residue, and fractionating the vapours obtained from this distillation and the vapours from the vapour-phase cracking to obtain a motor fuel.  Crude oil is fed through a line 1, heat-exchanger and line 6 into a flash tower 8, from which the flashed vapours pass through a line 67 into a tower 66.  The unvaporized oil, cooled by passage through a heat-exchanger 13, the re-boiler element 15 of a solvent-stripping tower 54, a heat-exchanger 17 and a cooler 19, enters a mixing chamber 20, where it is mixed with solvent, e.g. liquefied butane mixed with lighter gaseous hydrocarbons supplied through a line 21. The oil-solvent mixture is passed to a settling tank 23 provided with a baffle.  The bitumen collecting at the bottom is discharged through a line 25 and pumped through the heat-exchanger 13 to a stripping tower 30 in which solvent is distilled off and collected in an accumulator 33 for return to the mixer 20, the bitumen being discharged through lines 39, 41 to storage.  The oil-solvent mixture discharging from the separator 24 through an automatic level device 43 is pumped through heat-exchanger 17 to the stripping tower 34 where the solvent is distilled off and collected in a receiver 57, the oil being discharged through a line 63 into a tower 65.  Bottoms collecting in the tower 65 are discharged through lines 76, 78 to a low-temperature viscosity-breaking mild-cracking section 79 of a furnace 80.  The cracked products are separated into liquids and vapours in a separator 83, and the vapours are cracked in a high-temperature section 86 of the furnace 80, the cracked products being cooled by an arrester 88 by contact with cold condensate supplied from the tower 66 through lines 92, 95, and then passed to a flash tower 90 from which vapours pass to the tower 65.  The liquid residue, which is a refractory fuel-oil, is evacuated through lines 102, 103 to storage, sent for further solvent treatment to the tower 8, or fed through a line 107 to mix with the bitumen evacuated from the tower 30.  The primary fuel oil from the separator 83 is passed through a line 109 to an evaporator 113 from which vapours pass to a condenser 115 and receiver 116, the condensate being returned as reflux to the evaporator 111 or directed through a line 121 to the tower 65.  The residual fuel oil is sent to storage through a line 125 or through a line 127 into the tower 8.  The light fractions passing off from the top of the tower 65 are fractionally condensed and collected in receivers 134, 139.  Specifications 412,461 and 413,530 are referred to.
