Granted: 1913-02-13
Abstract: 11,175. Leitner, H. May 10. Regulation, automatic systems and apparatus for. - In an automatic regulator of the kind described in Specifications 21,145/04, 25,784/04, and 6690/06, the main contact arm controlling resistance in the main circuit supplied by the battery and dynamo is so arranged in connexion with a subsidiary resistance-controlling arm or arms that a reverse movement of the former in either direction does not immediately effect a movement of the latter. In the arrangement described, a dynamo A, the field of which is controlled by a resistance b, supplies a circuit D through one automatic cut-out C, a battery B being in parallel with the circuit. Resistance a controlling the potential at the circuit terminals is automatically varied by the movements of a main contact arm c, which are effected by a reversible motor d according to the effect of the circuit voltage on a relay e. The field circuit resistance b is also controlled by the main arm c, which operates a subsidiary contact arm f travelling over the resistance b. To avoid hunting from the action of the regulator on the system, the connexion between the main and subsidiary arms is constituted by insulated forked members g, which enables the resistance a to be varied within certain limits without affecting the strength of the dynamo field. More than one subsidiary arm may be operated in this way by the main contact arm.

Stereotype.-Stereotype matrices are made of paper or other fibrous material impregnated with condensation products of phenols or its homologues and formaldehyde or its polymers and substances soluble in water but refractory at the casting temperature of stereo metal, such as the silicates or aluminates of the alkali metals. In preparation, a sheet of heavy absorptive paper such as blotting paper is saturated with sodium silicate, dried, and immersed several times in a condensation product of phenol and formaldehyde which becomes infusible under the influence of heat, the sheet being dried after each immersion. The sheet is then heated to about 70‹ C. and strengthened by attaching to one side of it a sheet of thin paper by a solution of sodium silicate. The opposite face of the sheet is polished with baryta, talc, &c. and pressed on the forme in a heated press. The phenol products are then rendered infusible by heating the matrix on a hot metal plate, a curved plate being used if the matrix is to be used for casting curved plates. In a modification, the sheet of absorbent paper is first treated with the phenol product, baked, treated with sodium silicate, dried, and backed up.

Abstract: 17,692. Messerschmitt, A. Aug. 1. Hydrogen - producing furnaces.-In the manufacture of hydrogen by the alternate oxidation and reduction of iron, the reaction mass is subjected to combined external and internal heating in a modification of the furnace described in Specification 12242/12. An external heating-space 1 communicating with a coke-generator 2 and with a chimney 3 surrounds a shaft 4, which holds the reaction mass and opens into a heating-chamber 5 at the bottom end by way of an iron inset 7. Gas from pipes 18, 17 and an air blast from tangential nozzles 22 are introduced into the chamber 5, which is provided with a grate 16. The heating-gases traverse the reaction mass in the shaft 4 escaping by way of the valve 9 into the upper part of the coke generator 2. For reducing the iron, water-gas is introduced by the pipes 18, 17, and, as before, the escaping gases are led by the pipes 10, 11 into the generator 2, where they are burnt with air supplied by a pipe 12 and utilized for the external heating. The reduction phase mav be made to coincide with the heating-phase by introducing through the pipes 22 small quantities of air to mix with the water-gas. The oxidation phase is effected by admitting steam bv a valve 13, the valve 9 being closed. The hydrogen passes through pipes 17. 19 into a condenser 20. In a modification, Fig. 3, the gas and air for the direct heating are introduced by tangential nozzles 27, 28 into an annular passage 31, whence they flow downwards through passages 29 into the lower heating-chamber 30. For reduction purposes, water-gas with small amounts of air is introduced into the passage 31, the mixture passing into the chamber 30 and thence through the reaction mass, which is simultaneously reduced and heated. The spent gases from the reduction stage are burnt in the external heating-chamber 25 with air supplied by a blast-pipe 33. In the oxidation phase, the chimney 35 is closed and steam admitted by a pipe 36 to the chamber 25, which contains chequer-work 26 for superheating the steam on its way to the shaft 4. The hydrogen formed passes through the chambers 30, 31 and into the tank 37.

Vaporizing-apparatus.-In burners consuming oil vapour and steam for use in stoves, ranges, &c. adapted originally to burn solid fuel, in which vaporization of the oil and water is effected by heat from the burner itself, the oil and water are led through capillary tubes to the vaporizing-surfaces in order to ensure even and uninterrupted vaporization. The oil and water supply-pipes 2, 3, respectively, open into different parts of a vaporizing-chamber 1, which is heated by burners 5 fed from the lower part of the chamber, and is packed with insulating-material 12 in its upper part. Each pipe 2, 3 is surrounded by asbestos, and the end of the pipe 3 is mounted telescopically in a short tube 10, Fig. 3, having a serrated mouth. In order that the oil may flow steadily to the vaporizing-surface, the end of the tube 2 is brought within such a distance of the surface that a single drop of oil spans the gap between them. A conducting-bar 18 with an upturned end 19 is provided to supply heat to the plug 11, on which the water is vaporized when only a small flame is being produced. The supply of oil and water is controlled by needle valves 6, 7, respectively, the operating-handles 13 of which are provided with numbered. marks registering with indicator arms 14, and so arranged that when corresponding numbers are in register, the correct proportions of oil and water .will be fed to the vaporizer. The arms 14 are rigidly secured to collars 15, which are rotatable on the valve casings, but are moved only as the valve seats wear away, when projections 17 placed at the zero point of the handles 13 come into contact with the arms.
