Abstract: 523,969. Control of two A.C. motors. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Jan. 18, 1939, No. 1703. Convention date, Feb. 26, 1938. [Class 38 (iii)] An induction motor 1, operating, for example, a compressor in refrigerator plant, has main windings 4, 5 connected by means of a switch 13, in series for connection to 220 volt mains, and in parallel for connection to 110 volt mains; the winding 10 of an auxiliary fan motor 2 being connected in shunt to one of the windings 4, 5 so that in their high voltage series connection the windings 4, 5 operate as a voltage divider for the winding 10 of the auxiliary motor. A heater winding 24 for an over current relay 23, a coil 21 effecting bye-passing of the compressor at starting, and a relay coil 22 for controlling the connections of a condenser 8 and auto transformer 7 determining the phase of current in an auxiliary main motor winding 6, are all connected in series with motor winding 4 so as to respond equally to motor current for operation on either supply voltage. The relay 22 responds when the initial rush of starting current subsides. The circuit of the auxiliary winding 6 of the motor 1 is connected across the main winding 5 and is energized correctly on either supply voltage. The Specification as open to inspection under Sect. 91 comprises also a system in which two main motors, each with its current responsive devices energized in series with one of its main windings, are started sequentially. In this system the switch effecting the sequential control includes. a latch held by a coil carrying the current flowing through one main winding of the first motor 20 that when the current subsides the switch is operated to start the second main motor. This subject-matter does not appear in the Specification as accepted.

Abstract: The processes for the manufacture of filaments, films &c. from cellulose acetates and other organic acid esters of cellulose or of cellulose esters as described in the parent Specification and in Specifications 340,436 and 340,437, are modified by employing for the coagulation baths or as the baths with which the coagulated materials are treated directly on emergence from the coagulation baths, liquid non-solvents which are plasticizers for the cellulose esters and ethers, such as tri-aryl phosphates, alkyl phthalates and aryl sulphonamides.  The plasticizers may constitute the whole of the coagulation &c. liquid, and in order to secure this a mixture of plasticizers which produce a liquid, may be employed; and with the plasticizers there may be mixed solvents or non-solvents or both solvents and non-solvents for the cellulose derivative, but in such mixtures the plasticizers should be present in high proportions, say of 60-90 per cent.  In examples, acetone solutions of cellulose acetate are spun into tricresyl phosphate-acetone and diethyl phthalate-acetone mixtures.  According to the Provisional Specification any swelling agent which is a non-solvent may be used. Specifications 177,868 and 179,234, [Class 2 (ii), Cellulose &c.], also are referred to.

Title: Improvements in process for the production of aluminium oxide from aluminium nitrate, in which the decomposition of nitric acid is reduced to a minimum
IPC: C01F7/308
Filed: 1931-01-20
Abstract: A process for producing aluminium oxide by heating hydrated aluminium nitrate is characterized in that the heating is effected in stages. In the first stage, the nitrate is fused in its water of crystallization at a temperature not exceeding 150 DEG  C., until 40 per cent of the water and nitric acid is evolved; the material approaching solidification is then heated to a temperature not exceeding 250 DEG  C. until 75 per cent of the water and acid is evolved, and in the third stage above 250 DEG  C. but not exceeding 450-500 DEG  C., when complete decomposition is effected. By operating in this manner, the production of lower oxides of nitrogen is reduced to a minimum.

Patent GB-998024-A (GB)
Title: Electrolytic processes employing alkyl grignard electrolytes
IPC: C25B3/13
Filed: 1962-01-22
Abstract: In an electrolytic process employing an alkyl Grignard electrolyte, heat produced during electrolysis is removed by circulating a coolant stream of alkyl halide in indirect heat exchange relationship with the electrolyte, the alkyl group of the alkyl halide coolant corresponding to the alkyl group of the alkyl Grignard reagent. Thus, should there be any leakage, the electrolyte and coolant will be non-reactive.  The coolant is circulated through coils in the electrolytic cell and is itself cooled externally of the cell.  In one example the coolant is maintained liquid throughout its circulation, Fig. 1 (not shown). As illustrated, in Fig. 2, the coolant acts as a vapour type refrigeration system.  The coolant liquid vaporizes in the electrolytic cell under pressure controlled by a valve 32 and the vapour is then withdrawn and compressed at 34, cooled at 37 to condense it and the resultant liquid recycled through the cell. The controlled <PICT:0998024/C6-C7/1> pressure of the coolant vapour determines the temperature to which the electrolyte is cooled. The cooling coils may be finned and connected in parallel or series parallel arrangements. Consumable anodes are used, e.g. of Pb, which may be in the form of plates or Pb shot in foraminous baskets. The electrolyte comprises the alkyl Grignard reagent in a solvent including an ether or tertiary amine.  It may also include an additional ether, e.g. tetrahydrofuran and benzene, toluene or xylenes for increasing electrolyte conductivity and excess alkyl halide to react with Mg plating out at the anode.  In preparing (C2H5)4Pb the electrolysis was run at 20-100  DEG C., an anode and cathode current density of 0.2-100 A/foot2, 20-50 volts and higher and at a subatmospheric to low superatmospheric pressure, e.g. 60 p.s.i.g.  Organometallic compounds of Zn, Al, Mg, Cd and Sn and (CH3)4Pb and (C2H5)4Pb are referred to as are also Grignard reagents having alkyl groups with 1-8 carbon atoms. Examples of alkyl halides which may be used with alkyl Grignard electrolytes having the same alkyl group are CH3Cl, CH3Br, C2H5Cl, C2H5I, n-C3H7Cl, n-C3H7Br and n-C4H9Cl. Specifications 839,172 and 882,005 are referred to.

Abstract: 1325519 Conveyer belt CLOUTH GUMMIWERKE AG 18 Jan 1972 [1 Feb 1971] 2368/72 Heading B5A Apparatus for manufacturing rubber conveyer belting having steel wire or cable reinforcement includes a pair of stationary cable clamps 4, 7, a pair of movable cable clamps 2, 8 and a cable tensioning device 3 for ensuring that cables are held under tension during rubber application and vulcanization. Initially the clamps 2, 8 are closed and the sections of cable between each stationary and movable clamp are tensioned by the device 3. The stationary clamps 4, 7 are closed and rubber is applied by an applicator 5. The clamps 4, 7 are then released and the clamps 2, 8 and device 3 are moved so that the rubber covered length of cable is taken into a vulcanizing press 6. Simultaneously, a fresh press length of untensioned cable is drawn off a supply reel 1 and a vulcanized press length of belting is collected by a wind-up drum 9. The clamps 4, 7 are reapplied and the clamps 2, 8 and the device 3 returned to their initial positions. The movable clamps 2, 8 are again closed and the cable sections lying between the movable and stationary clamps are tensioned by the device 3. Chains or cables 10 interconnecting the movable clamps 2, 8 and driven by double-acting hydraulic or pneumatic cylinders (14, 15, Fig. 3) ensure that the tension in the cable section between clampss 2 and 4 is approximately the same as that between clamps 7 and 8, any difference being compensated for by a second tensioning device 23.
