Title: Unbalanced load detection in alternating current system
IPC: H02H7/06
Filed: 1965-02-16
Abstract: 1,079,374. Automatic control systems. WESTINGHOUSE ELECTRIC CORPORATION. Feb.16, 1965 [Feb.27, 1964], No.6645/65. Heading G3R. In a system including a plurality of polyphase sources 1, 2 operating in parallel, a load unbalance detecting arrangement includes a current transformer loop circuit 8, 8, 9, 10 for producing a signal current proportional to the difference in load currents of the sources 1, 2, and a voltage sensing circuit 11 for each power source, the circuit 11 including means for deriving voltages in phase and in quadrature with the signal current and means for vectorially combining the derived voltages with the phase voltages of the power source. The output from the circuit 11 may be applied to a voltage regulator 7 associated with the relative power source so that the unbalance is automatically corrected, or it may be applied to an indicating or protective device. Each circuit 11 includes a capacitor 12 and a resistor 13 energized by the signal current, a first transformer 14 having its primary 16 connected across the capacitor 12 and having secondaries 17, 18, 19, and a second transformer 15 having its primary connected across the resistor 13 and having secondaries 21, 22 which together with the secondaries of transformer 14 are connected as shown to the output phase lines of the power source. The Specification describes with reference to a vector diagram Fig. 2 (not shown) how voltages in phase with and in quadrature with the signal . current are derived, and how these derived voltages are combined with the phase voltages to modify the voltage to which the regulator 7 responds, whereby there is maintained a proper reactive load division between the sources 1, 2. By suitably modifying the connections, the circuit 11 . may be used to respond to unbalance of real load instead of reactive load. The circuit 11 may also be modified to provide a D. C. output signal with polarity and magnitude determined by the direction and magnitude of the unbalance Figs.3 to 5 (not shown).

Title: Improvements in or relating to devices for connecting markers in automatic telephoneexchanges
IPC: H04Q3/00
Filed: 1955-03-08
Abstract: 768,757. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. March 8, 1955 [March 8, 1954], No. 6858/55. Class 40 (4). In an arrangement for selecting one of a number of circuits for connection to a marker, two relay chains are provided, each containing a relay for,each of the circuits, the operation of one of the relays of one chain disabling the other chain. By this means, a connection is ensured unless both relays are faulty. In a first embodiment, Fig. 1, the arrangement is applied to a number of circuits L1 ... L3 which may be calling for connection to a signal receiving device S in the marker M. If L1 is calling contact K2 is closed, completing over the t-wire circuits for R1 and R7 in series and for R2 and R8 in series. Relay R1 belongs to the chain R1, R3, R5 and R2 belongs to the chain R2, R4, R6. Relay R7 operates more quickly than R8 and opens the circuit for R2 and R8. If R1 operates satisfactorily it brings up R11 which is associated with the R1 ... R5 chain. Relay R11 opens the operating circuits of the other relays of this chain and provides a holding circuit for R1. Relay R1 closes a circuit over the v-wire for the operation in series of R13 and MR in the circuit L1, the latter relay connecting L1 to the receiver S. If, however, R1 fails, R13 remains down and slow operating relay R9 comes up to disconnect R7 which on releasing connects up the R2, R8 circuit again and these relays then complete the connection with the aid of relays R12 and R14 in a manner similar to that in which R1, R7, R11 and R13 should have operated. In a second embodiment, Fig. 2 (not shown), such an arrangement is used in the marker to select a free line from a group of such lines, free potential being signalled over the t-wire, the selected line being marked over the v-wire. Arrangements are provided in this case to keep one chain in operation until a fault occurs in it, whereupon the other chain is used until it becomes faulty when the first chain is again taken into use and so on. Arrangements are also provided to give an all-lines-busy signal when necessary.

The pumping speed of a barium ion-getter pump is increased by utilizing very -pure degassed barium which is distilled into an evaporation furnace in the pump from a separate distillation chamber. In the arrangement shown an evaporation furnace 3 located in the main pumping chamber 1 is connected by a pipe 13 to a distillation chamber 7 containing a distillation furnace 11. Metallic barium is fed to a crucible 10 through a shield 15 from a loading assembly comprising a gate valve 40 and a pipe 42. The chambers 1 and 7 are roughly evacuated by fore pumps 30 and 50 each comprising an oil diffusion pump and an oil rotary pump connected in series. The crucible 10 is then heated by a coil 14, with the shield 15 open, to degas the barium, after which the shield 15 is closed and the heating increased to vaporize the barium, which condenses on the wall 12 of the furnace 11. A heating coil 16 provided with a heat shield 23 is then energized to liquify the barium, which flows to the pipe 13 which is heated by a further coil 17 to maintain the flow of barium to a reservoir 4 in the evaporation furnace 3. The reservoir 4 is heated by a coil 18 to vaporize the barium, which is ejected through apertures 19 and deposited on the wall of the chamber 1 to form a film 20. A tungsten filament 21 and positive grid 22 are provided to ionize inert gases such as argon and helium. Connection to the various heating coils is effected by way of terminals 24 and 25 and a gauge is connected at 26 to measure the vacuum in the main chamber 1. A manifold (not shown) is connected at one end 5 of the chamber.

Abstract: 1,027,397. Benefication of beryllium ore. UNITED KINGDOM ATOMIC ENERGY AUTHORITY and COUNCIL FOR SCIENTIFIC & INDUSTRIAL RESEARCH. Feb. 7, 1963 [Feb. 22,1962], No. 7021/62. Heading B2H. . Beryllium ore is concentrated in a process in which mica is removed from the pulp which is then conditioned with acid fluoride and given a collector additive for the removal of iron minerals by froth flotation, the pulp then being washed and given a further froth flotation to recover the beryllium ore. As shown in the flow diagram the ore ground and constituting a pulp is fed to a cyclone washer 1 with a dispersant such as sodium silicate added at the rate of 1.5 1bs/ton. By this means slimes smaller than 24 microns are removed to waste line 2. Water is added to the underflow washer 1 and a second washer 4 is employed to remove a further proportion of slimes. The underflow from washer 4 proceeds to a tank 6 in which an amine acetate collector and a frother such as methyl isobutyl carbinol are added. In tank 6 a pulp density of 20% solids is achieved and the contents pass to froth flotation cell 8 in which the float is substantially mica and the tailings comprise the beryl values which pass to tank 10. In tank 10 the acid fluoride is added in the form of sodium fluoride at 16 1bs/ton and sulphuric acid, sufficient to produce a pH of 3. 5, at 6 1bs/ton. Proceeding to a further tank 11 the pulp has a petroleum sulphonate collector added at the rate of 0. 5 1bs/ton and proceeds to a froth flotation cell 12 in which the float comprises iron and iron minerals and the tailings pass to the three stage cyclone washer 15,16 and 17. The underflow of the washing stage is fed to a tank 19 where sulphuric acid is added at the rate of 0. 5 1bs/ton, to adjust the pH to 2. 5; a petroleum sulphonate collector also being added at this time. The pulp is then transferred to froth flotation chamber 20 the float of which contains the beryllium values and is thickened at 22 and passed by way of tank 27 to a drum filter 28 the scrapings from which are dried in rotary kiln 29. Using distilled water an ore assaying 0. 32% beryllium oxide gave a concentrate assaying 9.63% with a recovery rate of 85%.

Title: Apparatus for producing negatively charged polyatomic compounds by electron attachment and analysing the same by mass spectrography or mass spectrometry
IPC: H01J49/12
Filed: 1959-03-03
Abstract: 888,887. Heavy-ion-beam tubes. VAKUTRONIK VEB. March 3, 1959 [April 25, 1958], No. 7439/59. Class 39(1) An ion source for producing negatively charged, but undissociated, relatively large and complex polyatomic molecules for subsequent analysis in a mass spectrometer consists of a low pressure discharge chamber 1 with one or more hot cathodes 2 in which a substantially neutral plasma having a low electron temperature and a low potential gradient is formed in an auxiliary gas of low ionizing voltage, e.g. caesium vapour, mercury vapour or argon. The plasma is magnetically constricted in a non-uniform magnetic field set up between asymmetrical pole-pieces 4, 15. Pole-piece 15 is also the discharge anode and pole-piece 4 is also an intermediate electrode. Immediately in front of pole-piece 15 is the ion emission slit 10 and the test gas or vapour is introduced in front of the slit 10 e.g. by evaporation from a movable and electrically heatable crucible 9, through the agency of a sharply directed gas or vapour stream, or mechanically by means of ultra-sonic oscillators or other vibrating surfaces. Several crucibles 9 or a multiple channel gas radiator may be provided. One crucible includes a calibration substance. The ion emission slit 10 is covered by a pre-diaphragm 14 and is movable by an amount greater than the diameter of the prediaphragm. The ions passing through the slit 10 subsequently pass through by an accelerating electrode 17, auxiliary aperture diaphragm 21 and adjustable main aperture diaphragm 22, cylindrical lens 23 and separating magnet chamber 33 of the spectrometer. The target chamber forms an ion image tube 30 and includes an adjustable photographic plate 27, a secondary emission cathode 28 and an aluminized fluorescent screen 31. Electrons removed with the molecular ions fall on a plate 26 in the vicinity of the entry of the beam into the magnetic field, the plate being screened with lead to prevent the X-rays generated from affecting the fluorescent screen. The ion beam is directed on to the apertures in diaphragms 21, 22 by means of a pair of deflecting plates 18 behind the ion emission slit 10.
