Abstract: 553,248. Electric control systems. SAUTER AKT.-GES. FABRIK ELEKTR. APPARATE, F. (formerly FABRIK ELEKR. APPARATE SAUTER AKT.-GES, F.). Dec. 15, 1941, No. 16145. Convention date, Dec. 13, 1940. [Class 40 (i)] The condition of apparatus such as a waterheater is controlled in accordance with a prearranged schedule by means of adjustable resistances w1, w2 ... which are connected across the control circuit in succession by a clockdriven rotary switch 3. At the receiving point the control circuit passes through a rheostat 17 and one winding 22 of a differential relay the other winding 23 of which receives constant current. If the current in the winding 22 is greater or less than that in the winding 23 when the switch advances to a new position, the armature 24 operates to energize one of the windings 14, 15 of a motor 13, which rotates in the appropriate direction to shift the electrodes of the water-heater F and also the arm 18 of the rheostat 17 until the differential relay is balanced. As a modification, the rheostat 17 is omitted and the winding 23 receives current through a transformer from the heating circuit of the water-heater. To facilitate adjustment, the resistances w1, w2 ... are arranged side by side and the sliding contacts k1, k2 ... are carried by plates 33 formed with indicating lugs 31, so that the values of the resistances are shown by the distances of the lugs from a datum line. Alternatively the resistances may be arranged axially about a central point.

Title: Improvements in method and apparatus for accreting molten material
Inventor: BIXLER HARLEY HOWARD
IPC: C23C2/04
Filed: 1962-04-27
Abstract: In a hot dipping process a member such as a copper rod is continuously moved through a heated crucible via a nozzle located at the bottom of the crucible, molten metal such as copper being introduced into the crucible when the rod reaches its melting point and the speed of the rod through the crucible being such e.g. 25-50 cms./min. that it does not deteriorate by melting.  As shown in the drawing the rod 2 is passed through a drawing section 3, a shaving cutter 4 which removes the surface oxide and forms a seal with the surface of the rod.  The rod is driven through an evacuated passage 5, 6, 8, 25 by rolls 9 and 10 and enters the crucible 26 through nozzle 29.  The crucible is heated by coil 36 and when the melting temperature of the rod is reached its speed increases and a servomotor 37 actuated by a sensing means 38 lowers a graphite block 34 into a molten metal reservoir 32 and the molten metal then flows into the crucible.  An inert gas is maintained above the molten metal in the crucible and the coated rod is discharged via nozzle 43 and cooling sprays 44 to a shock isolation loop 45 comprising an arm 46 pivoting about a shaft 47, pulleys 48 and counterweight 49.  As the rod emerges from the nozzle it enters pulleys 48, the reaction causing arm 46 to rotate and open valve 50 which supplies air to the servo motor 42 which controls the speed of the discharge drive wheels 55 and 56.

Abstract: Organic colouring matters are produced in finely-divided form by treating with water the complex compound obtained by reacting the organic colouring matter with a metal halide capable of forming a complex therewith, i.e. a Friedel-Crafts catalyst and compounds formed when the halogen atoms of Friedel-Crafts catalysts are partially replaced by organic radicals, e.g. alkoxy or aryloxy radicals, as in aluminium dichloro-phenoxide. Friedel-Crafts catalysts specified are the halides of aluminium, antimony, boron, tin, iron, titanium, tellurium, zirconium and double salts, complex salts and coordination compounds containing such halides, e.g. sodium aluminium chloride, and the compounds of aluminium chloride with alcohols, ethers, esters, ketones, or sulphur analogues thereof, and with heterocyclic, aromatic, aliphatic, or cycloaliphatic nitrogenous bases.  The water for decomposition of the complex may be provided as steam or ice or as aqueous solutions of acids, bases, or salts, or mixed with other liquids.  Dispersing agents may also be present during the decomposition.  In examples, the following are made into complexes with aluminium chloride sometimes sodium chloride, methanol, or acetone being present, in ethylene dichloride or benzene or other solvent or without a solvent, the complex being then decomposed with water; (1) copper phthalocyanine, (2) indanthrone, (3) 3.31-dichlorindanthrone, (4) 4.41-dibenzoylamino-1.11-dianthrimide carbazole, (5) dimethoxydibenzanthrone, (6) terephthal -5.51-dibenzoylamino-1.11-dianthraquinonylamide, (7) indigo.
