Title: Improvements in incandescent lamps fed by liquid fuel
IPC: F23D99/00
Filed: 1921-04-22
Abstract: 162,254. Lambercier et Cie, J. April 23, 1920, [Convention date]. Vaporizing-apparatus; mantle supports.-In. an incandescent vapour lamp, the vaporizer is arranged below the level of the flame and the vapour passes through superheating tubes extending above the fuel reservoir, which is not under pressure. The vaporizer is heated partly by conduction from the burner-head through the mixing- tube and partly by conducticn from the vapour superheating tubes. As shown in Fig. 1, the fuel oil passes from an annular reservoir 1 through a pipe 2 to a tubular non-conducting vaporizer 3 at the bottom of a mixing-tube 12 which supports the mantle 5 by means of radial metal arms 11, a metal rod 8 and a nickel rod 6. The vapour produced in the vaporizer 3 is conducted through a. superheating tube 18, 19 passing above the mantle to a jet 14, and is mixed with air in the tube 12. The vaporizer 3, which is provided with a removable stopper to facilitate cleaning, is heated at starting by alcohol burnt in a dish 20. The rod 8 may be supported on the tube 12 by a grating 9 instead of the radial strips 11. In modifications, the superheating tubes are arranged adjacent to one another either near or within the flame, and the mantle support is external to the flame. In another modification the oil reservoir is arranged above the flame. When burning very volatile fuels the superheating tubes need not extend as high as the mantle, and are connected straight across the burner head or surround the burner head to form a superheating chamber.

Filed: 1940-07-22
Abstract: 541,260. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd. July 22, 1940, No. 12001. Convention date, Oct. 17, 1939. [Class 40 (v)] In a negative feedback amplifier which may be of the type described in Specification 493,671 the feedback is produced by a coil coupled to the output transformer and in series with a blocking condenser and a resistance in the cathode lead common to the input and output circuits. The Figure shows an arrangement in which a feedback coil 11 is arranged in series with a resistance 9 and blocking condenser 10 the whole being shunted by resistances 7, 8. The amount of feedback is varied by resistance 8 the moving contact of which carries the space current and thus maintains good contact and prevents gain variation by a poor contact. The bias is varied simultaneously with the feedback and the arrangement may be such that the gain in the amplifier times the transmission efficiency of the feedback path is a constant. The Specification as open to inspection under Sect. 91 describes also the application of the invention to a two-way repeating station with pilot wire control for temperature changes and adapted for two or four wire operation either side. This subject-matter does not appear in the Specification as accepted.

Patent GB-678279-A (GB)
Title: Improvements in or relating to stable emulsions
IPC: C08F212/08
Filed: 1949-05-09
Abstract: Stable aqueous emulsions are made by treating an emulsion copolymer prepared from 0.5 to 30 per cent of an unsaturated monocarboxylic acid, e.g. acrylic, methacrylic or cinnamic acid up to 99.5 styrene with a base having a dissociation constant greater than 10-8, e.g. sodium, potassium, lithium and ammonium hydroxides, methylamine, ethylamine, ethylene diamine, di- and tri-methylamines, mono- and tri-ethanolamine, morpholine, piperidine, tetraethanol-, phenyltrimethyl- and trimethylbenzyl-ammonium hydroxides.  Copolymers prepared from at least 50 per cent of styrene, 0.5 to 30 per cent of the unsaturated acid and up to 49.5 per cent of one or more other monomers, e.g. acrylonitrile, methyl acrylate, methyl methacrylate and a -methyl styrene may be similarly treated.  The treatment may be effected by mixing the emulsion with aqueous base or by bubbling gaseous ammonia or amine through the emulsion and removing excess by heating or steam distillation.  The copolymers are prepared in the presence of catalysts, e.g. acetyl, benzoyl, lauroyl, hydrogen and sodium peroxides, sodium, potassium and ammonium perborates, and potassium persulphate, emulsifying agents, e.g. sodium oleate, potassium stearate, salts of triethanolamine and dodecyl methylamine, alkali metal rosinates, sodium lauryl sulphate, sodium alkylarylsulphonates and dioctyl or di-2-ethylhexyl sodium sulphosuccinate.  The catalyst may be added continuously or in increments. Polymerization may be conducted at the reflux temperature, which is maintained constant by addition of monomer. The process may be continuous or semi-continuous.  Polymerization may be stopped by lowering the temperature, adding an inhibitor or rapidly steam-distilling to remove monomers.

Filed: 1974-12-17
Abstract: 1454940 Coating apparatus INTERNATIONAL SHOE MACHINE CORP 17 Dec 1974 [6 May 1974] 12569/76 Divided out of 1454939 Heading B2L A cement lasting apparatus comprises a last to receive an upper and an insole on its bottom carried by a support, a cement applying member which initially occupies an inner position spaced inwardly from the corner between the margin of the upper and the insole, means for moving the cement applying member outwardly into the corner under relatively high pressure, means for subsequently causing the cement applying member to be maintained in its outward position under a relatively low outward pressure, and means for then moving the cement applying member along the corner in a cement applying stroke while it is retained in the corner. The lasting machine is described in Specification 1454939 (Divisions A1-A3), and the cement applying apparatus is generally similar to that described in Specification 1437675. As shown, cement applying nozzles 396, Fig. 2, are lowered onto an insole 480 upon a last 478 having an upper with margins 496 forming corners to receive tht nozzles. Pneumatic servos 430, Fig. 3, are energised via a valve 508 from a compressed air source to lower the nozzles 396 onto the widest part of the insole 480, where they are maintained at their inwards position relative to the upper margins. A valve 518 is then opened automatically to supply line pressure air through a pipe 524, a valve 526, a pipe 528, a shuttle valve 530 and a pipe 532 to a servo 418, which moves the nozzles 396 outwardly under relatively high pressure into the corners between the upper margins 496 and the insole. Simultaneously, pressure air in the pipe 524 is passed through a pilot line 536 to a pneumatic timer 538. After a time delay, line pressure passes through the timer 538 to a valve 540 which admits line pressure through a pipe 542 to a valve 526, which disconnects the pipe 524 from the pipe 528 and instead connects it to a pipe 544. A pressure regulator 546 in the pipe 544 reduces the line pressure, so that reduced pressure is transmitted via the shuttle valve 530 to the servo 418, to keep the nozzles 396 in the corner between the margin 496 and the insole under a reduced pressure. The nozzles 396 are then traversed along the insole 480, until they reach the end of the margin 496. The direction of nozzle travel is reversed and a servo 350 is energised to extrude cement through the nozzles 396. At the end of the travel of the nozzles 396 back along the insole 480, the cement applying servo 350 is deenergised, the servo 418 is actuated to move the nozzles 396 inwardly of the insole away from the corners between the upper margin 496 and the insole, and the servos 430 are energised to lift the nozzles away from the insole. Finally, lasting straps 130, 132, 134 are engaged against the sides and margin 496 to wipe the latter over the cement applied to the insole 480, &c.

Title: Device for use on board aircraft and flying machines for determining the drift and the ground speed as also for determining bearing angles
IPC: G01P3/36
Filed: 1931-04-29
Abstract: 366,372. Sighting-apparatus for aircraft. PATTIST, M. P., 163, Riouwstraat, Bandoeng, Java. April 29, 1931, No. 12624. [Class 97 (ii).] Apparatus for determining drift and ground speed of aircraft comprises a main frame carrying a scale, a pivoted rule adapted to move over the scale, and a further frame hinged to the first frame and carrying a graduated ring slidably arranged so that its centre may coincide with any desired graduation of the rule when the latter is in its central position. In the form shown a sector shaped frame A fixed to the aircraft so that the ground may be viewed through the open part 4 has pivoted to it at 7 an open frame B which is provided with a rule 6, spaced parallel wires 9 or a transparent disc having corresponding marks, and a pointer 8 running over the scale 2 on the frame A. When the frame B is in the central position the rule 6 having a scale of air speeds measured from the pivot 7 is parallel to the longitudinal axis of the aircraft. A frame C hinged to the frame A at 11 carries a slidable ring 13 which may be moved along the frame C by the screw spindle 14. The frame C may be swung over on the hinge 11 to lie under and against the frame A as in Fig. 2. The ring 13 carries an angularly adjustable circular plate 22 to which a circular paper sheet 40 graduated round its edge may be secured by the hinged clamping ring 27. To measure the angle of drift the frame B is turned on the pivot 7 until objects on the ground seen through the opening 4 move parallel to the rule 6 or wires 9. To measure the ground speed, the frame B is centralized, the frame C brought against the frame A, the centre of the paper sheet 40 which may be marked with concentric circles moved by the screw 14 to a point on the rule 6 representing the air speed, and the plate 22 with the paper turned until the course is read off on the paper against the rule 6. The frame C is then swung out of position and after the frame B has been set to the drift angle again brought against the frame A, a pencil mark being then drawn on the paper 40 along the rule 6. These operations are then repeated with the aircraft flying on a different course. The line joining the intersection of the two pencil lines and the centre of the paper 40 gives the strength and direction of the wind. The ground speed for a given course may be read off on the rule 6 at the point of intersection of the pencil lines. When used for determining bearing angles, three needles 35 connected by a strip 38 are mounted at the centre and opposite ends of a diameter of the plate 22. The frame B is swung to one side and the plate 22 turned until the object the bearing angle of which is desired is sighted in the plane of the needles 35. Methods of determining wind speed and direction and ground speed when only one or two mountains can be seen through the clouds are described.
