Abstract: 696.058. Travelling-wave tubes. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 11, 1950 [July 15, 1949], No. 18764/49. Class 39(i) In a travelling wave amplifier there is interposed between the gun and main helix 8 an auxiliary helix 7 unconnected to any external source of waves, which has the same wave velocity as the main helix but a different D.C. potential or, as preferred, a different wave velocity as by making the pitch or diameter different but the same or nearly the same D.C. potential, so that the wave and beam velocities are unequal in the auxiliary helix; it is stated that random noise fluctuations in the beam induce a noise wave on the auxiliary helix which reacts back on the beam to induce a bunching modulation and that the voltage induced in the main helix 8 by random noise fluctuations and by the modulation component are out of phase and can be made to cancel. Exact cancellation can be achieved by varying the D.C. potential of the auxiliary helix 7 and the total beam current. The helices may be replaced by waveguides. Helix 7 is much shorter than helix 8 by a definite fraction in terms of wavelength. The molybdenum helices 7, 8 are supported by glass rods 10, and input and output guides 11, 12 associated with flanges 13 and chokes 14 are coupled to the ends of helix 8; a drift tube 15 connected to helix 7 is interposed between the two helices. The helix 8 may be copper plated to reduce losses, and the glass rods 10 may be coated with colloidal graphite at the vicinity of the centre portion of helix 8 to inhibit oscillation. The Provisional Specification states in addition that the voltage of the auxiliary helix may be less than that of the main helix for example 100 volts less. The auxiliary helix or guide may be replaced by a resonator detuned from the signal frequency.

Drawings to Specification. [Class 40 (iv)] The Specification describes a toll system identical with that described in Specification 489,545, but the claims are directed to the clearing and release arrangements. When the calling party hangs up, the signal equipment at the first exchange sends a forward clearing signal which is repeated until a backward release signal is received. The signal equipment also responds to a clearing signal sent back when the called party hangs up. When a through signalling byepath is provided at tandem, the clearing signals pass through tandem without effect. Specification 479,881 is referred to in the Provisional Specification.

Abstract: 1,033,066. Casting-machines. E. Q. SYLVESTER. May 14, 1963 [May 21, 1962], No. 19066/63. Heading B3F. In an apparatus for forcing metal upwardly from a ladle through a pouring tube into a mould positioned on the end of the pouring tube, the top of the pouring tube is initially sealed by a closure member which is disintegrated by the molten metal as it fills the pouring tube. The ladle 20 is mounted in an enclosure 16 beneath a cover assembly 38 through which the pouring tube 14 passes by way of a bellows seal 46. A mould assembly 52 is seated upon the upper end of the tube on an asbestos gasket 74 overlying an aluminium disc 66 which closes the top of the pouring tube. High pressure air may be supplied to a conduit 78, the disc 66 and gasket 74 yielding sufficiently to allow said air to enter the pouring tube and force metal therein back into the ladle. When casting is to be performed, the pressure in the tube is relieved and pressure air is supplied to the enclosure 16 via conduit 88, forcing metal up the tube, to melt the closure 66 and enter the mould. Modifications describe different methods of securing the closure discs and connecting the pressure air supply to conduit 78 to facilitate the assembly of the ladle and the cover 38.
