Title: Process for preparing organometal compounds
IPC: C25B3/13
Filed: 1962-11-19
Abstract: Metal alkyls are made electrolytically by making the selected metal consisting of As, Sb, Pb, Bi, or An the cathode, and using as alkylating agent either (a) an ester, in which the carbon chain is 1-70 C atoms, and the acid has a pKa value in water of less than 6, or (b) an "onium" salt which is weakly acid or basic, and is dissolved in a non-hydroxylic catholyte which has a higher reduction potential than the alkylating agent, e.g. amines, nitriles, sulphones, glycol ethers, ketones, ethers, carboxyamides, or alkyl thio cyanates. The process avoids the use of alkylating agents containing another metal.  Suitable esters are, lower alkyl halides, sulphates, phosphates, and carboxylates. "Onium" salts include tetra-ethyl ammonium iodide, tetra benzyl arsonium bromide, and ethyl triphenyl phosphonium iodide. Preferably a permeable diaphragm is used, the anolyte being sodium carbonate solution.  The catholyte may also include a conducting salt. Electrolysis is effected at 20-70 DEG C., at 4-30 V., and at current densities up to 1 A.S.Cm.  Examples of solvents include acetonitrile, hexa methyl phosphoramide, N-methyl caprolactam, acetone, and ethyl thiocyanate. Conducting salts include alkali metal or alkaline earth halide compounds, e.g. lithium bromide, triethyl phenyl phosphonium iodide, and potassium thiocyanate. In examples, tetra and tri ethyl and methyl compounds of lead, tin, arsenic and bismuth are described. Specification 814,609 is referred to.

Title: Improvements in control means for fuel burners
Inventor: MASKELL JOHN STOWERS
IPC: F23N5/22
Filed: 1963-11-06
Abstract: 1,091,563. Controlling burners. BABCOCK & WILCOX Ltd. Nov. 6, 1964 [Nov. 6, 1963], No. 43901/63. Heading F4T. A control means for carrying out the following three operations in sequence: (1) Advancement of an oil burner, opening a steam atomizing valve, opening of air register doors and opening of an oil valve; (2) closure of the oil valve and opening of a purging steam valve; (3) retraction of the burner, closure of the air register doors and closure of the atomizing steam valve and the purging steam valve, comprises a shaft 2 rotated by a handle 16 or by a piston in a cylinder 38 in one direction to three different positions, means being provided to prevent the rotation of the shaft in the opposite direction. The three positions of the shaft are determined by a roller 30 engaging in three recesses (26A, 26B, 26C) in a disc 26 secured to the shaft, the roller being mounted on a lever (28) biased by a spring (29). The three positions of the shaft are indicated by lamps 44A, 44B, 44C energized in turn by an arm on the end of the shaft engaging contacts. The piston is connected to a carrier 40 which is rotatably mounted and carries a spring urged pawl (34) which engages three teeth on a ratchet wheel 8 secured to the shaft. The piston is spring biased to a retracted position. When a push button is actuated, a solenoid valve 46 admits air to the cylinder 38 and the piston advances causing the shaft to rotate through 120 degrees and when the push button is released the piston is returned to the end of the cylinder causing the pawl (34) to slide over the ratchet wheel 8 to a rest position in engagement with the next tooth of the ratchet wheel. Rotation of the shaft in the opposite direction by means of the handle is prevented by the piston abutting the end of the cylinder. The shaft carries four cams 20A, 20B, 20C, 20D engaging rollers on spindles having arms adapted to actuate pneumatic valves 21A, 21B, 21C, 21D. Fig. 4 shows the cams in the off position. When the shaft is turned clockwise through 120 degrees the two cams 20A, 20B move the pneumatic valves 21A, 21B and the piston in the air cylinder 24E advances the burner and the piston valve 22A opens to supply atomizing steam. The burner moves a fifth pneumatic valve 21E which in conjunction with valves 21B, 21C acts through piston and cylinder 24B to open the register doors and through piston valve 22C to supply oil to the burner. When the shaft is turned a further 120 degrees to the purge position the cam 20B allows valve 21B to return to its start position and the cams 20C, 20D move the pneumatic valves 21C, 21D. The oil valve 22C therefore closes and the piston valve 22D opens to supply purging steam. When the shaft is turned a further 120 degrees to the off position the burner retracts, the air register doors then close, and the atomizing and purging steam valves close.

Filed: 1973-09-20
Abstract: 1440609 Controlling frequency changers SIEMENS AG 20 Sept 1973 [22 Sept 1972] 44295/73 Heading H2F In a frequency changer comprising an inverter 5 supplied with power from a current-controlled rectifier 2, a quenching circuit 3 comprises a commutating capacitor 22 connected across the intermediate D.C. lines 3a, 3b by means of a thyristor 19 and having an inductor 21 connected across the capacitor 22 by means of a further thyristor 20. The thyristor 19 is turned on, when it is required to turn off the operative thyristors of the inverter 5 whilst the second thyristor 20 is turned on when the voltage across the first thyristor 19 has a predetermined level in one direction, so that the inductor 21 is able to reverse the charge on capacitor 22. As described, the system is applicable to supplying variable power at variable frequency to a synchronous, asynchronous or rectifier motor 1. The rotor position is monitored by a Hall or permanent magnet device 7 while a speedresponsive signal is obtained from a tachogenerator 6 and is compared with a desired speed signal at 13. The speed-error signal is fed to a speed controller 14 which compares a current-controlling signal with the input current as monitored at 15. A current controller 17 thus determines the conduction angle of rectifiers 2. Firing pulses for the thyristors of the inverter 5 are derived at 8, 9, 10 which also provide a differentiated pulse from 26 to trigger the turnoff thyristor 19. An appropriate blocking input is available at 35. Commutating capacitor 22 is initially charged from a source 23 via diode 24. A further connection 28 blocks firing pulses from firing stage 10 while commutating. When thyristor 19 is turned on, commutating capacitor 22 is discharged reversely via the conducting thyristors of the inverter 5 and via the motor 1 and begins to recharge from the constant current id. When the charge reaches a level determined by a Zener diode 33, a signal is sent on line 34 to release trigger pulses for the next pair of thyristors of the inverter 5. When the voltage across thyristor 19 reaches a further level, determined by Zener diode 30, thyristor 20 is turned on so that inductor 21 reverses the charge on capacitor 22 in preparation for the next commutation. Thyristor 19 may be triggered by a train of pulses lasting during the commutating period. Photo-electric coupling may be provided between stages 30 and 31.
