Title: Plasma generator
IPC: H05H1/24
Filed: 1962-10-12
Abstract: 959,150. Discharge apparatus. UNITED STATES ATOMIC ENERGY COMMISSION. Oct. 12, 1962 [Dec. 7, 1961], No. 38687/62. Heading H1D. In a plasma generator, the plasma is created at a point remote from electrodes and other structures, and is produced within a containing magnetic field by the initiation of a travelling ionizing wavefront in a gas disposed within the field. As shown, a plasma generator comprises a cylindrical shell 6 with a first end closure 7 and a second end closure 8 having openings for connection to a vacuum pump 17 and a gas source 18, an electrode 11 supported by an insulator 14 within an aperture 13 in the closure 7, a conductive sleeve 12 spaced apart from and coaxial with the electrode 11, and magnet coils 21, 22, 23 for producing a magnetic mirrortype field of the configuration indicated by dashed lines 25. To generate the plasma a charge of deuterium or the like is first admitted to the chamber 9 and then a high energy pulse, derived from a circuit including a high voltage power supply 26, a pulse line 28, an ignitron 32 and a trigger pulse generator 37, is applied to the electrode 11; a discharge is thereby produced between the electrode 11 and the grounded sleeve 12 creating a hydromagnetic ionization wavefront which follows the magnetic field and proceeds axially through the chamber 9, leaving behind a fully ionized gas. Before the wavefront reaches the end closure 8, electrode 11 and sleeve 12 are short-circuited by an ignitron 39 which is fired, at a definite interval after the ignitron 32 starts to conduct, by a portion of the triggering pulse from the unit 37, which portion is passed through a delay circuit 43 for such interval. This short-circuiting has a braking effect on the wavefront which is thus stopped before it reaches the end closure 8. The ionized plasma within the containing magnetic field is thus substantially free from contaminants as it has not contacted the various structural elements of the generator. In a modification (Fig. 2, not shown), initial break down of the gas in chamber 9 is facilitated by providing a spark gap at the centre of electrode 11.

Title: Method and apparatus for acoustically removing contaminants from water
IPC: C02F1/36
Filed: 1976-09-17
Abstract: 1516602 Picking up floating matter OCEAN ECOLOGY Ltd 17 Sept 1976 [19 Sept 1975] 38691/76 Heading BID [Also in Divisions H3 and H5] Floating sawdust or oil 122 is thrown upwards from the surface 121 of water into a collecting space 109 by acoustic waves of sonic or ultrasonic frequency produced by a submerged, electrically powered generator 90 and focussed on a region 120 just below surface 121. As shown the generator is mounted on a bridge 88 supported by an annular float 80 which is free to slide vertically between projecting arms (75) on a barge or self-propelled scavenging vessel (Fig. 5 not shown), the buoyancy of the float being adjusted by partly filling it with sea water using a hand pump (85), so that the oil can flow over it and between two outlet pipes 102 which support chamber 105 over the region 120, so that oil is thrown into the chamber up nozzle 107 and subsequently removed by pump 115 to storage tank (74). The generator 90 comprises a dished transducer 96 immersed in castor or silicone oil 95 under diaphragm 94 and focusses on a spherical region 120. Waste heat from the generator, dissipated by vanes 93, reduces the oil viscosity. An array of independently pivotable generators (Fig. 4 not shown) could focus on a common region, and an alternative generator (Fig. 3 not shown) has an elongate transducer to produce a cylindrical focal region which creates a sheetlike stream of oil. In Figs 1, 2 (not shown) the generator is located in a tank and throws oil over one side wall (20), the oil-water interface being maintained level with the focal region by controlling the delivery of oil-water mixture to the tank and the discharge of water from the tank bottom.

Title: Circuit arrangements for controlling the speed of commutator or induction motors
IPC: H02P27/02
Filed: 1966-09-01
Abstract: 1,102,316. Control of A.C. motors. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 1 Sept., 1966 [4 Sept., 1965], No. 39000/66. Heading H2J. [Also in Division G3] Thyristors 3, connected in the supply circuit of an A.C. commutator motor 2, are triggered by signals from a frequency comparator 5 which receives a reference signal from the mains. The motor drives an auxiliary machine 7, fed from control frequency generator 8, and acting as a frequency converter to provide an output at mains frequency to the comparator 5 when the motor is operative at a desired speed. If the speed of the motor decreases due to increased load, the output of the machine 7 increases in frequency momentarily and its waveform is advanced in phase with respect to the signal derived from the mains. This increases the duration of the conductive periods of the thyristors during subsequent half-cycles of the supply voltage and so restores the speed to its former value by increasing the driving torque The behaviour with a decreasing load is similar to that described. When the motor is adjusted to a lower speed by altering the control frequency, the supply current is interrupted by the absence of trigger signals, and enforced braking may be initiated by reverse-current or eddy currents until the prescribed speed is attained. In another arrangement, the motor under control is of the three-phase induction type with pairs of thyristors in each supplyline. Speed fluctuations are reduced by frequency or phase modulation of the control frequency, the modulating signals being obtained from a tachometer generator. Alternatively, a low-pass filter 23 is associated with the control frequency generator 8 or with a phaseshifter between the machine 7 and the comparator 5 for this purpose.

Title: Improvements relating to thread spinning machines
IPC: D01H1/24
Filed: 1958-12-03
Abstract: 892,638. Control of motors. BEMBERG A.G., J. P. Dec. 3, 1958 [Dec. 13, 1957], No. 39030/58. Class 38 (3). A spinning machine for producing endless synthetic threads has variations in the titre of the thread produced by varying the speeds at which the thread is drawn off, the speed variation being controlled by a programme device, the starting acceleration of the driving motors being reduced by supplying the motors at a reduced voltage by way of fixed series resistors or by autotransformers the deceleration being assisted by direct current or short-circuit braking which is automatically brought into operation when the supply current is switched off. A programme device initiates the operation of the spinning machine by closing a switch S, thus energizing coil 13 of relay 9 over a contact 18. Relay 9 picks up to supply the motor M from terminals U, V, W which aresupplied from a three-phase source by way of a voltage reducing device such as an autotransformer or series resistors. Pick-up of relay 9 closes contact 15 to energize the coil of relay 11 which picks up to close contact 22 (i.e. the position shown). Coil 17 of relay 10 remains de-energized since contact 14 is open. When it is desired to stop the motor M, the programme device opens the switch S. Coil 13 is thus de-energized and relay 9 drops out, removing the supply to the motor M, closes contact 14 and opens contact 15 to de-energize relay 11. Relay 11 is made slow to release, thus maintaining contact 22 closed so that coil 17 of relay 10 is energized over contacts 14, 22. Relay 10 picks up to isolate relay 9 by opening contact 18; closes contact 19 to supply transformer 20 and rectifier 21 and connects the rectifier 21 to the motor M to produce dynamic braking thereof. When the motor has stopped relay 11 times out to open contact 22 to de-energize relay 10 to remove the dynamic braking supply from the motor.

Abstract: 1,215,678. Knitting-machines. H. STOLL, G. STOLL, E. STOLL, E. STOLL, J. STOLL, A. STOLL, R. E. STOLL and M. STOLL. 5 Aug., 1969 [9 Aug., 1968], No. 39102/69. Heading D1C. A lock for a flat machine includes appropriately contoured stitch-transfer and stitchreceiving tracks into which butts can be selectively diverted so that stitch transfer can take place between the beds in either direction irrespective of the traverse direction. A system for acting on needle butts comprises a transfer cam 1 with needle advancing protuberances 2, 3 defining a transfer track 6, and retractable receiving cams 5, 5' defining track 7. The entrances to track 7 are guarded by bolt switch cams 4, 4'. If transfer is to take place during traverse from right to left cam 4 is inserted in the lock corresponding to the bed from which transfer will occur. The needles are thereby prevented from entering track 7 advanced by projections 2, 3 and then received from the latter by receiving needles advanced by cam 5' in the opposite bed. Transfer may similarly occur between the beds during the opposite traverse by inserting cam 4'. In the modified lock shown switch cams 4", 4"' and receiving cams 5", 5"' for jacks and an axiliary jack cam 9 are provided so that transfer can occur in both directions on a single traverse. Transfer needles are selected by inserting jack cams 4", while receiving needles are selected by auxiliary jack cams 9 which bring the jacks into the range of receiving cams 5"'. For transfer on the opposite traverse cams 4"', 5" are operative.

A probe for insertion into molten metal (e.g. copper or iron) in a furnace for determining the oxygen content of the metal comprises a solid mass of a mixture of a self sinterable solid electrolyte, retaining ionic transport properties at the temperature of the molten metal, and a fugitive binder. Solid electrolyte. Suitable electrolytes are stabilized zirconia, pure thoria, pure hafnia, and thoria or hafnia to which has been added lanthia, yttria or scandia. Suitable fugitive binders are polyvinyl alcohol, polymethyl methacrylate, ethyl cellulose, zirconium nitrate in an alcoholic and/or aqueous dispersion, and zirconyl nitrate in an alcoholic and/or aqueous dispersion. The mixture maybe sintered before the probe is used or when the probe is used for the first time. Probe constructions. As shown in Fig. 3, a probe tip is detachably mounted on the end of an electrically conductive lance 12 and comprises a quartz or boron nitride tube containing a mass of solid electrolyte 27 in which is embedded a thermocouple junction (e.g. Platinum-platinum/rhodium ally or tungsten-tungsten/rhenium alloy) having leads 28, 29 protected by an alumina, mullite or alundum sheath 30. The tube is surrounded by a metal sheath 25 itself surrounded by a ceramics envelope 36. A fugitive cap 39 is formed of a material (e.g. copper or iron) that will melt or be burnt on use of the probe. The probe tip contains a known gas in contact with the solid electrolyte and may be hermetically sealed or may be connected to a tube through which a known gas is continuously supplied. Suitable gases for this purpose are air, CO/CO 2 , CO 2 /O 2  CO 2 /N 2 , N 2 /O 2 , H 2 O/H 2  N 2 O, NO, N 2 O 5 , and NO 3 . A different configuration is shown in Fig. 4.

Title: Improvements in or relating to Fuel Elements for Nuclear Reactors
IPC: G21C3/33
Filed: 1966-09-05
Abstract: 1,152,823. Fuel elements. GENERAL ELECTRIC CO. 5 Sept., 1966 [19 Oct., 1965], No. 39627/66. Heading G6C. A fuel element comprises a tube containing nuclear fuel with a chamber provided at one end of the tube to collect fission product gases, the plug at this end of the tube having a flat inner surface forming one end of the chamber, and a spring within the chamber applying a force against both the end plug and the fuel disposed within the tube to prevent the fuel from sliding in shipment, the spring contacting only the centre region of the flat inner surface of the plug. This arrangement substantially reduces the probability of the spring melting during the welding of the end plug and even if the eutectic temperature of spring and end plug is exceeded, the resulting molten material is sufficiently removed from the weld region for contamination of the weld to be avoided. In the preferred embodiment the end loop of the spring is turned through 90 degrees with respect to the next adjacent loop and the top of the loop contacts only the centre of the end plug. This is both the coolest region of the plug and that furthest from the weld area. In addition, the end loop may be coated with chromium so that the loop and end plug (made of zirconium alloy) together have a eutectic temperature higher than that with an uncoated loop. The loop is thus even less likely to melt during the welding of the end plug.

Abstract: 1,023,874. Evaporators, film-type. FARBENFABRIKEN BAYER A.G. Oct. 8, 1963 [Oct. 10, 1962], No. 39652/63. Heading B1B. In an evaporator wherein the liquid is distributed as a film on the inner wall of an externally-heated cylinder, and the film is wiped by blades pivoted in a rotating support within the cylinder, the swinging-out movement of each blade is arrested by a stop which bears against the support and prevents abrasion at the wiping-edge of the blade. As shown, the stops are in the form of flaps 3 bent out of the plane of a straight blade 1 at its upper and lower ends. Each blade has pivot-spindles 2 inserted in bores 5 in rotatable ring 4. The dotted lines in Fig. 2 represent the blade at rest. When the ring 4 is rotated in the direction of the arrow, the blade swings outwards, and edge 7 of the flap 3 bears against the outer edge of the ring. This prevents abrasion of the wiper-edge 8 of the blade against the inner wall 6 of the evaporator. In an alternative embodiment, the stops are formed by cutting out part of the upper and lower ends of one arm of an angular blade.

Title: Power or percussion type hammer
IPC: E02D7/12
Filed: 1960-11-18
Abstract: 958,688. Percussive tools. VULCAN IRON WORKS Inc. Nov. 18, 1960 [Dec. 29, 1959], No. 39787/60. Heading B4C. [Also in Divisions E1 and F1] A hammer driven by internal-combustion comprises a structure having axially aligned cylinders 23, 32, a piston-rod 42 having pistons 44, 46 coacting with the cylinders, guides 14 supported by the structure, a ram 16 slidable on the guides and connected to the piston-rod 42 by a connecting rod 55, and means 70 (Fig. 4), for alternately injecting fuel into the cylinders and operated by reciprocatory movement of the rod 42. The guides are connected to a base 12 to which is flexibly attached an anvil 10 which is adapted to rest upon or be secured to a pile or other device which is to be driven. A rack 72 (Fig. 4), mounted on the rod 42 drives pumps 70a, 70b supplying fuel to the cylinders. The hammer is hoisted on to the pile by means of pulley 38 and the ram is raised to fire the gases in the cylinder 32 by compression. The downward force exerted by the ram is controlled by the amount of fuel supplied to the cylinder 32, the cylinder 23 being supplied with a constant amount of fuel sufficient to raise the ram. Downward movement of the ram 16 and piston 44 compressses the air in the cylinder 23, fuel and additional air being respectively supplied to this cylinder by the pump 70a and plunger pumps 90 (Fig. 1), actuated by a cam (not shown) on the rod 42. When the compression is sufficient to ignite the charge, the rod 42 and ram are lifted, the air pressure within a housing 26 uniting the cylinders rising. As the piston 44 rises an exhaust port (not shown) is uncovered and then the end of a passage 84 is uncovered to supply scavenging air from the housing to the cylinder 23. The piston 44 compresses the air in the cylinder 32, fuel and additional air being respectively supplied to this cylinder by the fuel pump 70b, and a plunger pump 90, actuated by cams 42b on the rod 42. The cylinder 32 may have expansible radial chambers (Fig. 5, not shown), or an additional annular volume which serve to store energy for the down stroke of the piston 46 which is caused by ignition of the charge under compression. As the ram and rod 42 descend an exhaust port (not shown) is uncovered and air is drawn into the housing through a non-return valve 88. The cylinder 32 may be cooled by encasing it within a shield (Fig. 2, not shown), open at the upper end, and by fitting in the shield opposite the exhaust port a Venturi device so that the exhaust gases induce a flow of air downwardly over the cylinder.
