Title: Improvements in semi-conductive arrangements
IPC: H01L29/72
Filed: 1958-01-13
Abstract: 883,906. Semi-conductor devices. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Jan. 13, 1958 [Jan. 18, 1957], No. 1215/58. Class 37. In a semi-conductor device comprising a pair of adjacent zones of opposite conductivity types and of different resistivities a third zone is arranged in ohmic contact with the zone of higher resistivity and in rectifying contact with the other zone in such a position that it may be isolated from the rest of the zone of higher resistivity by the space charge layer produced at the junction of the first and second zones when a suitable reverse bias is applied across the junction. In the embodiment shown in Fig. 2, comprising a grown NPN type germanium transistor body, the base zone 8 of which is of higher resistivity (20 ohm cms.) than the collector zone 9 (1 ohm cm.) and only 30Á thick, a P + zone is formed astride the collector junction by diffusion from a gold gallium alloy electrode. In operation the current between the emitter zone 7 and base contact 10 is controlled by the reverse bias across the collector junction and is cut-off when the space charge layer completely outflanks the P+ zone. The device may also be used as a photosensitive switch when this junction is reverse biased sufficiently to cut-off the emitter current. Low intensity light incident on the space charge region produces carriers therein which in flowing through the series resistance of the collector zone reduce the collector bias and hence the width of the space charge layer to reconnect the base contact 10 and thus produce a considerable current. In the above arrangement the emitter zone may be replaced by a P or P+ type zone. A further arrangement (Fig. 9) is formed from a strip 33 of P type silicon with a bevelled upper surface 39 by diffusing impurity into the surface to form an N-type zone 34 and providing a P+ emitter zone 32, a P+ base contact 35 and a collector connection 34 on the resulting body. A further embodiment is shown in Fig. 8. In all the devices described above the conductivity types of the various zones may be reversed with appropriate changes in the polarity of the biasing sources.

Title: Improvements in or relating to the recovery of uranium values
Inventor: CHILD JOHN
IPC: C22B60/02
Filed: 1960-01-14
Abstract: Uranium values are recovered from a fluoride slag of a reducing metal (e.g. Mg, Ca, Ba, Li, Na or K) by treating the slag with a mixed aqueous solution of an aluminium sulphate or nitrate and a sodium salt of the same acid to bring the slag into solution as sodium aluminium fluoride together with the metal and uranyl salts of the said acid.  The resulting solution is treated to recover the uranium from it by solvent extraction with an organic solvent, e.g. tributyl phosphate or by ion-exchange.  In an example a magnesium fluoride slag was ground in suspension as an aqueous slurry in a vibratory ball mill to reduce the particle size to an average of 2 microns. This slag containing up to 5% of enriched uranium was treated with a mixed aqueous solution of aluminium nitrate and sodium nitrate and the mixture was refluxed for 16 hours by which time about 92% of the slag had been brought into solution.  After pressure filtration to remove any residue the filtrate was contacted with tributyl phosphate and the uranium which was extracted into the latter was recovered therefrom by washing with 3N.HNO3.  When sulphates are used, ion-exchange is used for the extraction of uranium values.

[Classes 38 (ii) and 38 (iv).] Boosting by transformers.-An arrangement for supplying variable A.C. to illuminating circuits comprises a transformer having a rotatable primary winding c<1>, c<2> energized from the supply and a number of secondary windings e connected to the several illumination circuits a<1>, a<2>, a<3>, the primary and secondary being relatively movable into coupling with each other so that the illumination circuits are energized in succession. The primary may be wound on a rotor c and supplied through sliprings f, the rotor being rotated so that the poles thereof come into coupling with the poles of the stator in which the secondary windings e are mounted. The primary and secondary windings may be arranged on U-shaped cores, the horns of which come into magnetic relationship during rotation of the rotor. The pole shoes of the primary and secondary winding poles may be extended so that the total coupling of the primary winding with the secondary windings is maintained constant. In a modification, the secondary windings are wound on cores arranged parallel to the axis of rotation of the rotor on which the primary winding is similarly arranged with shoulder pieces which extend so as to complete the magnetic circuit with the cores of successive secondary windings during rotation. In a further modification the primary and secondary windings are arranged on fixed cores and a rotatable magnetic piece is arranged to couple the primary winding with successive secondary windings. The amount of coupling with the various secondary windings may in each case be adjusted by making the poles of the secondary windings adjustable so as to vary their air gaps, or providing non-magnetic shielding pieces which may be inserted in the air gaps. Where the number of illumination circuits is greater than the number of secondary windings these windings may be connected to a distributer driven in synchronism with the rotating part of the transformer and the illumination circuits connected to or brushes co-operating with slip rings or contacts on the distributer. An additional invariable, but adjustable, voltage may be injected in each output circuit by tapped secondary windings of an auxiliary transformer or the secondary windings of the output circuits may be connected in " star " and the additional voltage inserted in the " neutral " lead. The additional voltage may be taken from a part of the primary of the main transformer or, alternatively, the whole of the primary may be connected in the " neutral " wire of the output circuits in which case the system functions as an auto-transformer with variable coupling between the common primary winding and the several additional windings.

Abstract: Textile goods are dyed or printed by treating, if necessary at elevated temperatures, in the presence of strongly alkaline-reacting agents with azoic dye precursors which contain one or more reactive hydrogen atoms preferably attached by way of nitrogen, oxygen or sulphur or which are capable of forming such atoms during the process and with uncoloured polyfunctional compounds which contain two or more CH2 = CH-CO- groups attached by way of nitrogen or which are capable of forming such groups during the process and thereafter converting the azoic dye precursors to dyestuffs in the usual way. The dye precursors may be diazotizable aromatic amino compounds or compounds capable of coupling.  Specified combinations are initial treatment with sulphanilic acid amide and coupling with C.I.  Azoic coupling component 13 or treatment with 1-amino-8-hydroxy naphtalene-3,6-disulphonic acid or N,H-diethanolamino -3-methylbenzene and coupling with diazotized para-nitraniline. The specified polyfunctional compound is hexahydro-1,3,5-triacryloyl-s-triazine.  The dye precursors may be fixed by steaming for 5 minutes at 100 DEG C.  rior to conversion to dyestuffs.  In fixing diazotizable aromatic amino compounds it may be advantageous to protect the diazotizable amino groups in a usual way such as acylation prior to fixation.  Examples are given of dyeing fabrics of cotton and viscose staple fibres.

Title: Improvements in or relating to bearing lubrication systems
IPC: F16N7/40
Filed: 1945-01-19
Abstract: 590,802. Lubricating. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Jan. 19, 1945, No. 1636. Convention date, Jan. 31, 1944. [Class 12 (iii)] A lubricating system for bearings, as of a gas turbine jet propulsion unit, has means for supplying lubricating oil to such bearings and means for removing oil from such bearings the latter means being retained in operation for a predetermined time after the supply of oil has been shut down. The bearings are thus drained of oil on shut down of the apparatus and leakage of oil with consequent fire risk is avoided. A main oil supply pump 21 for the bearings 23, 24, 25 is driven from the shaft 22, represented diagrammatically, of a gas turbine jet propulsion unit and each bearing has an oil scavenging pump 38, 39, 41 driven by an electric motor 45. The main pump 21 draws from a reservoir 26 and delivers through a cooler 29 to the line 31 supplying the bearings; a relief valve 32 allows the cooler to be byepassed if the flow therethrough is sluggish while a further reliefvalve 33, allows the oil to pass directly back to the reservoir 26 if the pressure becomes excessive. The electric motor 45 drives in addition to the oil scavenging pumps an auxiliary oil pump 43 to ensure an oil supply to the bearings at starting before the main pump is in operation. To start up a start push 52 is depressed thereby moving a contact piece 53 to close contact 56, 57 to energize the electric motor 45 and thereby give an oil supply by the auxiliary pump 43 so that the gas turbine jet propulsion unit can then be started up and thereafter the main oil pump 21 is in operation. After the gas turbine jet propulsion unit has been stopped a stop push 64 is depressed thereby moving the contact piece 53 to close contacts 56, 57, 66; the electric motor 45 continues energized and a solenoid 71 is energized to close a valve 47 whereby the inlet to the auxiliary pump 43 is deprived of oil. The movement of the valve solenoid 71 briefly closes a contact 74, 76 whereby a solenoid 77 is energized to retract a spring-urged pawl arm 87 driving a clockwork escapement wheel 93 and opening a contact 83, 82. After the predetermined time imposed by the clockwork escapement the contact 83, 82 recloses whereby a circuit for a release solenoid 55 is completed from battery 59 over wire 75, contact 74, 85 of valve solenoid 69, winding of solenoid 55, contact 82, 83, and back to battery 59; the release solenoid 55 returns the contact piece 53 to the full line position in which the contacts 56, 57, 66 are open so that the solenoids are released and the motor 45 is stopped; as the oil scavenging pumps have continued in operation for a predetermined time after the shut down of the oil supply the bearings are completely drained nf oil and thus the danger of leakage and fire is avoided. Specification 590,799, [Group XXVI7, is referred to.

Filed: 1922-01-20
Abstract: 190,650. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). Jan. 20, 1922. Calorimeters.-Apparatus for determining the total available heat per unit time of a flow of fluid comprises means for measuring both the quantity of heat per unit volume of the fluid, and the rate of flow of the fluid, and means for actuating an indicator in accordance with the determinations of the two measuring devices. The figure shows an arrangement in which the available heat of a combustible gas is measured. The heat per unit volume of the gas is determined by a calorimeter similar to that described in Specification 153,817, the gas being supplied from a meter 6 to a burner 5 and the heat being absorbed by air supplied from a meter 8. The initial and final temperatures of the air are imparted to resistance thermometers 12, 13 arranged in the circuit of a wheatstone bridge 15. In the circuit between the thermometers is a resistance 17, the distribution of which between the limbs of the bridge is adjusted by a slider 18 which is automatically moved by a ratchet device 20 when the galvanometer needle is deflected, so as to restore the balance. The rate of flow of the gas is determined by a meter of the Thomas type, comprising a heater 25, and resistance thermometers 28, 29. The thermometers are included in a wheatstone bridge 30, deflexions of the galvanometer needle being caused automatically to effect the adjustment of a rheostat 27 in the circuit of the heater to adjust the current so that a constant temperature-difference is maintained. The available heat per unit time is indicated by a wattmeter 39 one actuating coil 41 of which is connected across the heater 25 and is arranged in series with a variable resistance 42, the value of which in the circuit is determined by the position of the slider 18, and hence by the indication of the calorimeter. The other coil 45 of the meter 39 is connected in series with the heater. A recording watt-meter 38 with similarly connected circuits is also provided.
