Title: Method of and system for operating static rectifiers
IPC: H02P7/292
Filed: 1965-06-02
Abstract: 1,060,934. Rectifying. SOCIETE DE CONSTRUCTIONS ELECTROMECANIQUES JEUMONT-SCHNEIDER. June 2. 1965 [June 12, 1964; Dec. 23, 1964; May 13, 1965], No. 23513/65. Heading H2F. [Also in Division G3] The output voltage of a number of rectifier bridges I, II, III, IV in series, each bridge having two diodes and two controlled rectifiers, is controlled by operating a number of the bridges to give their maximum output and operating one bridge intermittently to give a variable output. Each bridge either conducts or does not conduct for whole half-cycles only. The rectifiers of each bridge are connected as shown so that the uncontrolled valves, such as D7, D8, pass load current when the controlled valves are not conducting. With the manual control K set at position 11 as shown bridges I and II conduct all the time, and bridge III is made conducting for three half-cycles in four. For automatic control of load current, say, the current is monitored at R 1  compared with a reference at G 0 , and the error signal fed to forwards and backwards counters D, Q, which control the static relay units R1 to R4, F1 to F4, and B1 to B4 (which are described with reference to Fig. 4, not shown). Rectifier control signals are produced at A1 to A8 and fed through transformers H1 to H8 to the controlled rectifiers. The invention produces fewer harmonics on the A.C. side than would a phase controlled rectifier.

Filed: 1928-08-15
Abstract: 295,641. Suida, H. Aug. 15, 1927. [Convention date]. Acetic acid.-The extraction of acetic acid from its aqueous solutions is effected in the liquid phase bv means of esters of monovalent or polyvalent alcohols with monobasic or polybasic cyclic acids, which esters have boiling points above 150‹ C., and the extracted acid is separated from the solvent by distillation. The process may be effected at a raised temperature so that some part of the extraction is effected in the vapour phase. In an example a 12 per cent acetic acid solution is caused to rise in an extraction column containing filling material, and dibutyl phthalate is caused to descend from the top. In another example preheated 25 per cent acetic acid is supplied at the top of a column upon which is mounted a rectifying column. Diethyl phthalate is supplied at the top of the rectifying column, and the bottom of the lower column is heated so as partly to vaporize the acetic acid. Other solvents mentioned are dimethyl dihexyl phthalates, esters of the naphthene acids, and high-boiling esters of henzaic acid. Specifications 218,271, 218,272, and 296,172 are referred to.

In a pneumatic conveyer of the kind in which loose material is elevated through an adjustable pipe by a suction pump, two chambers are provided which are alternately placed in communication with the suction pump and the suction pipe by valve means common to the chambers so that while one chamber is subjected to suction and the material is drawn into it, the other chamber is freed from suction to permit the discharge of the material therefrom. The chambers, pump and driving motor are disposed in compartments a, b, c, Fig. 1, respectively, of a container provided with wheels 6. A horizontal telescopic pipe 1<SP>1</SP> opens into compartment a and is connected by a flexible joint 2 to a vertical telescopic pipe 1<SP>2</SP>. The pipe 1<SP>1</SP>, is suspended by hangers 8 from a beam 7 which is supported by the container and is adjusted longitudinally by rack-andpinion mechanism. The length of the pipe 1<SP>2</SP> is adjusted by a line 12 connected to a winding drum 14. A housing 16, Fig. 3, placed in compartment a is divided into chambers 17, 18 by a partition 19. A cylinder 20 mounted in an opening in the partition has its ends in close contact with the walls of the housing and is provided with ports 29, 30 near one end and with larger ports 34, 35, Figs. 4, 5 for the greater part of its length. The cylinder 20 contains a rotatable hollow member 21 having (1) diametrically opposite ports 31, 32 between which, on one side only of the member are ports 33, and (2) a single large port 36. Each end of the member 21 is open, but a disc 22 inserted in it prevents through passage of the material. The disc carries a shaft 23 which can be turned either by hand or by the swinging movement of the plates 40 hereinafter described. The chamber 28 between the disc and the end wall of the housing communicates by ports 27 with a suction chamber 26 connected to the pump P. Perforated plates 40, Fig. 3, are hinged to the cylinder 20 and rest normally on lugs 41. Valves 42, 43 in the top of the chamber 17 and valves 44, 45 on the chamber 18 normally are maintained closed by springs. The valve 42 is connected to the valve 44 by a pipe 50 and the valves-43, 45 are connected by a, pipe 51. Material sucked up through the pipes 1<SP>2</SP>, 1<SP>1</SP> passes into the member 21 and out through the port 36 and whichever port 34, 35 is in register with it, into one of the chambers 17, 18. As the material accumulates in the chamber, it will press against a plate 40 and swing it upwards until it raises one of the valve stems 46, 47 and opens the valve 42 or 45. The opening of one of these valves effects also the opening of either the valve 44 or 43, and the empty chamber is connected to suction. When the member 21 is rotated the empty chamber is filled. The full chamber is discharged by opening the door 39.

Patent GB-798518-A (GB)
Title: Production of uranium
IPC: C22B60/02
Filed: 1944-12-01
Abstract: Uranium is produced by reacting uranium tetrafluoride with magnesium, and is preferably produced in massive form by preheating the reaction mixture, the amount of heat added being equivalent to the difference between the heat produced by reaction of the fluoride with calcium and that produced by reaction with magnesium, the uranium being thereby liberated in the molten condition.  The necessary preheat is given by heating the reaction mixture to between 500 and 700 DEG C. Preferably the particle size of the fluoride is such that more than 75 per cent passes a British Standard sieve of 60 meshes per inch, more than 60 per cent passes a sieve of 80 meshes per inch, more than 50 per cent passes a sieve of 100 meshes per inch and more than 40 per cent passes a sieve of 200 meshes per inch.  The magnesium preferably has a particle size not greater than that passing a sieve of 7 meshes per inch.  The reaction may be carried out in a sealed container having a refractory lining such as of calcium or magnesium oxide.  The reaction may be started by means of an electrically heated uranium wire extending into the mixture. Specification 796,589 is referred to.

Abstract: 1394279 Piezoelectric generators MANSEI KOGYO KK 23 May 1972 [8 June 1971] 24160/72 Heading H2A [Also in Division F4] A piezoelectric generator comprises an operating piece 10 slidably mounted on a frame 4, a striker 22 pivotably mounted (11) on the operating piece and a cam 6 arranged to swing the striker upwards, against a spring 23, as the operating piece is moved leftwards and then release it so that it strikes a piezoelectric unit 5. The operating piece 10 is mounted by means of pins 11, 12a which slide in slots 15a, 16a in the frame 4. The cam 6 is also pivoted (29) on the frame and is biased by a spring 30 towards its Fig. 1 position. As the operating piece 10 is moved leftwards, the engagement between a collar 26a on the striker and a projection 27a on the cam at first merely causes clockwise rotation of the cam. Once the cam reaches its limiting position (stop 28a engaging fixed pin 31), however, the collar 26a is forced upwards, thereby lifting the striker (Fig. 2, not shown), until it rides over the tip of the projection 27a, whereupon the striker is released. The operating piece 10 is returned by a spring 20, the cam being rotated anticlockwise during the return movement. A cigarette lighter incorporating the generator includes a fuel reservoir 2, an outlet valve 3 opened when movement of the operating piece 10 causes a lever 18 to pivot about its fulcrum 19, a nozzle 9 forming one electrode, and a second electrode 8 adjacent the nozzle.

Void [Published under Sect. 91 of the Acts]. [Class 38 (v).] In the protection of parallelconnected generators I, II, III supplying bus-bars 12 feeding distribution circuits of varied importance (for example, the installation on board a ship) on the operation of delay-action overload relays 4 or instantaneouslyacting reverse current relays 7 in any one of the supply leads from the generators, the feeder circuits are cut out one after the other beginning with the least important until only so much load is left on the sound generators as may be adequately dealt with. The sequential operation is effected by electrically interlocking the tripping relays 17 of the feeder circuits by means of switches 19 each one of which on operation prepares the tripping circuit of the next. Alternatively, the feeder tripping relays may be time-graded and operate in predetermined succession until the load is adequately reduced. The reverse-current relays in the supply conductors cause instantaneous operation of a relay 15 which cuts out all the feeders except that supplying the scavenging air blower for the Diesel engines and, in this case, the load is reduced by short-circuiting shuntregulating stages of the motor. A similar action is produced on substantial drop of voltage by the voltage relay 22. The feeder circuitbreakers may be tripped at will by manual operation of the switch 23. In a modification, Fig. 2 (not shown), when a fault develops in one of the generators the parallel connection between the two generators is interrupted (together with the supply to an unimportant part of the load) and with the supply coming from one generator only the feeders on that generator are successively cut out until the load is adequately reduce .
