[Also in Division C1] Particulate material to be heated is introduced into the downstream half of the volume of plasma 12 of an induction plasma torch by a feed tube 7 which terminates within the downstream half of the volume of plasma 12. This procedure inhibits growth on the tip of the tube 7 and sides of the silica plasma tube 1. The plasma gas is fed from a tube 3 to a distribution head 2 which causes a helical or laminar flow down the sides of tube 1. A mixture of flows can be produced. The coil 4 is hollow copper through which liquid, e.g. water or gaseous (e.g. plasma gas) coolant flows. A liquid jacket may surround silica tube 1. The feed tube 7 is a double walled tube sealed to a side arm 6 of the silica tube and water flows from inlet 9 through hollow tube 7 to outlet 10 and particulate material is introduced at 11. The plasma stream may flow vertically downward, horizontally, or be inclined at an angle of between 45 to 75 degrees to the vertical, as shown. The plasma gas may be argon, helium, neon, krypton, carbon dioxide, chlorine, oxides of nitrogen but preferably oxygen or mixtures of oxygen and argon.

[Also in Group XXXVIII] In a system for recording two dimensional stress strain diagrams, in which the paper feed is proportional to the displacement of the slider of the potentiometer of a measuring bridge which is adjusted, by means of a servomotor, to produce from the bridge the same unbalance voltage as a transducer bridge responsive to the strain of a test piece and the marking pen movement perpendicular to the direction of the paper feed is controlled in a similar fashion in accordance with the stress to which the test piece is subjected, the amplifier and detector arrangement which compare the unbalance voltages of the measuring and transducer bridges in each channel are switched sequentially between the two channels in order that the slope of the resultant diagram will be independent of the amplifier and detector characteristics. In Fig. 1, the two resistance strain gauge bridges 1, 2, 3, 4 and 5, 6, 7, 8 are responsive respectively to the deformation of, and stress applied to, the material under test. The unbalance voltages of these two bridges are each compared with the unbalance voltage of measuring bridges formed by potentiometers 10 and 11 or 12 and 13. The difference in the unbalance voltage being utilized after amplification and detection in 21, 22 and 23 to drive motor 14 or 15 to adjust the measuring bridge to the same unbalance condition as the corresponding resistance strain gauge bridge.

Abstract: 947,420. Blow moulding hollow articles. R. HAGEN, [trading as KAUTEX-WERKE REINOLD HAGEN]. Sept. 12, 1961 [Sept. 12, 1960], No. 32765/61. Heading B5A. After moulding and cooling a blow moulded article 20, relative movement between said article 20 and a stripper device detaches the flash therefrom. The flash 22 on the shoulder of the bottle and the annular flash 23 around the neck may be detached by one of the following: (1) Two two-pronged forks 25a, 25b which grip the flash 22 and accommodate the mandrel 15 and bottle neck between them. A greater force is applied to the longer prongs 25a so that both prongs move to the left as in Fig. 9 and remove the flash. The movement of the prongs may be at right angles to the movement of the mould 14 and the mandrel 15 is rotatable about a longitudinal axis as in Fig. 17 (not shown). (2) Pincers 75a, 75b, 76a, 76b grip the flash 22 and move apart to split the flash 23 along two indentations 31 formed in the flash 23 during moulding (Fig. 28). (3) Two tong-shaped parts 86, 87 carried on slides 82, 83 are forced together against the flash 22 by a compression spring 90 and forced apart to break the flash 23 by the cam action of a part 92, 93 on the tongs 86, 87 (Fig. 31).

Title: Improvements in or relating to ultra-high frequency systems
IPC: H01J25/10
Filed: 1947-12-12
Abstract: 654,173. Velocity-modulated tubes. SPERRY GYROSCOPE CO., Inc. Dec. 12, 1947, No. 32858. Convention date, Dec. 28, 1946. [Class 39 (i)] A plurality of microwave signals can be obtained from. a single velocity-modulation tube by constructing the input resonator so as to respond to a relatively broad band of frequencies, while a plurality of output resonators are more sharply resonant to frequencies within the resonance response range of the input resonator, or harmonics thereof. The input resonator may be given a sufficiently low Q to achieve this broad band response by plating the inner walls with a high resistivity conductor, or suitable choice of shape, or any other means. In the embodiment shown, the input resonator 11 may, by means of the switch 35, be excited by either of the oscillators 16 or 17, of frequencies f1 and f2 respectively, which may be crystal-controlled if great frequency stability of output is required. The frequency is multiplied n times by a multiplier driver stage 15, the resulting frequency nf or nf2 being fed into the input resonator 11 of the velocity-modulation tube 10 by coupling line 14. The high Q output resonators 12, 13 are sharply tuned to respective frequencies mf1 and pf2 which are harmonics of frequencies nf1 and nf2 respectively. Energy is transferred from resonator 13 by a coupling line 18 to a radiating antenna 19. Alternatively, energy is transferred from resonator 12 by coupling line 20 to a mixer 21 together with signals from a receiving antenna 22, producing an I.F. signal, the tube 10 acting in this case as the local oscillator in a superheterodyne receiving system. Thus the arrangement operates as a transmitting system, utilizing output resonator 13, or a receiving system, utilizing output resonator 12, according to the position of switch 35. In the modification of Fig. 2 (not shown), the output resonators are both tuned to different frequencies f1 and f2 which are within the response band of the input resonator. Both output resonators are coupled back to the input resonator so as to form a self-excited oscillator, a selective switch coupling in whichever feedback frequency is required. In this form, energy from both output resonators is fed to respective radiating antennµ. In both modifications more than two output resonators may be used, and the utilization of the different output frequencies may be simultaneous instead of alternative.

Abstract: 1472139 Aerials NATIONAL AERONAUTICS & SPACE ADMINISTRATION 26 July 1974 [10 Sept 1973] 33084/74 Heading H4A A switchable beamwidth antenna comprises a main reflecting dish 15, portions 16 and 18 of which are excited to generate a narrow beam and portion 16 of which is excited to generate a wide beam, to facilitate "acquisition" of e.g. data from an orbiting earth satellite. In a first embodiment, Figs. 2 and 3, a Cassegrain arrangement includes main paraboloid reflector 15, having its focus at 27, and rigid hyperboloidshaped sub-reflector 17 having foci at 31 and 29 respectively. Feed 19, supplied from microwave source 21 via conduit 23 illuminates subreflector 17 with a cone of radiation bounded by rays 23a, 25a. For narrow beam operation, Fig. 2, sub-reflector produces a reflected cone bounded by 23b, 25b which illuminates the whole of dish 15, which transmits the beam along bore sight axis 20. For wide beam operation, a signal from beamwidth command 39 causes the outer annular portion 35 of subreflector 17 to be retracted, Fig. 3, so that only the portion of the feed beam bounded by rays 43a, 45a is reflected by central portion 33 of subreflector 17, which illuminates portion 16 of dish 15, producing a transmitted signal of wider beamwidth. Figs. 6, 7, 8 (not shown), show various embodiments of the actuator mechanism 37. In another embodiment (Figs. 4, 5 not shown), for narrow beam operation a direct radiator (53) illuminates the main reflector 15, from a position on the focus thereof. A signal from beamwidth command 39 switches the microwave source 21 to a different radiator (51) which illuminates, in a Gregorian arrangement a concave sub-reflector 55, which is of a diametrical extent such that the beam reflected therefrom illuminates only portion 16 of the main dish 15 to produce a wide beam. The feeds 19 may comprise a square nest array of four S- band horns at the centre of which is nested a square nest array of smaller X-band horns (Fig. 10, not shown).
