Abstract: 627,446. Cooling dynamo-electric machines. PEEBLES & CO., Ltd., B., and RODGER, J. W. May 27, 1947, No. 14068. [Class 351 An annular core consists of a stack of laminations of similar non-circular shape angularly staggered about the axis so as to form one or more helical ridges at its outer or inner periphery, there being a number of holes arranged in a circle round the centre, certain of which are occupied by clamping bolts. Each lamination A is square with rounded corners A<SP>1</SP> The laminations are held together by bolts or'rivets G passing through selected holes A<SP>4</SP> which are equally spaced round a circle having a diameter slightly less than the square side. The bolts or rivets G also pass through the end plates B. The staggered arrangement of the laminations forms at the outer periphery of the stack four V-shaped helical grooves extending, round the stack. Each of the end plates B has four kidney-shaped openings registering with the groove ends. Air from the fan E and directed by the fan cowl F traverses the helical paths. A sheet metal cover H rests on the ribs and completely surrounds the stack. Staggering of the laminations may be done either singly or in groups according to the amount of cooling surface required.

Abstract: 698,005. Travelling-wave tubes. WESTERN ELECTRIC CO., Inc. June 15, 1951 [June 17, 1950], No. 14220/51. Class 39(i) An electron gun designed to produce a small diameter high-intensity beam, for example in a travelling-wave tube, comprises a cathode 11, accelerating and focusing electrodes 14, 15, and two magnetic pole-pieces 15, 17 (as shown, the electrode 15 is also one pole-piece), between which is established a converging magnetic field of paraboloidal form. The electrodes 14, 15 provide a converging conical beam and the magnetic field increasing in intensity in the axial direction in inverse proportion to the axial distance from the point to which the beam converges, provides interaction forces sufficient to cancel the space charge forces of the beam and the centrifugal forces due to the rotational motion of the beam.. The polepieces 15, 17 have paraboloidal surfaces whose foci coincide in the aperture of pole-pieces 17, with the focus of the conical beam. Magnetic members 21, 34 outside the tube envelope complete the magnetic circuit. The electron beam diverges in the aperture of pole-piece 17 to assume a cylindrical shape. This cylindrical shape is then maintained by an axial magnetic field. The two polepieces 15, 17 are spaced apart by a non-magnetic shield 18. Specifications 545,835 and 669,475 are referred to.

Title: Improvements relating to vacuum furnaces
Inventor: SEVERS MICHAEL JOHN

Filed: 1962-04-19
Abstract: 1,004,676. Vacuum heat treatment furnaces. EFCO FURNACES Ltd. April 18, 1963 [April 19, 1962], No. 15297/62. Heading F4B. A vacuum furnace including means for admitting a " harmless " gas to the vacuum vessel during or after heating, means for effecting forced circulation of the gas between the charge and a surface of a cooling wall, and means for causing a cooling medium to flow in contact with another surface of the cooling wall to remove the heat from it. The furnace may be of the type in which the charge is contained in an evacuated vessel which is placed inside a heating cover, such as a pit or bell, to be heated; or of the type in which the charge is contained in a chamber in an evacuated vessel. One embodiment of the latter type is shown in Figs. 1 and 2. The charge is contained in the chamber 11 which is supported within a cylindrical double-walled vacuum vessel 10. The charge is heated by a grid of heaters 30 within the chamber 11. Gas is admitted to the vacuum chamber through the port 18. The shaft 21 of the centrifugal fan 20 passes through the end wall 16 with a vacuum seal 22. Fig. 3 (not shown) gives an example of a suitable seal. When the vessel contains a vacuum, an effective seal is obtained, but when the vessel contains gas at atmospheric pressure the seal is released enabling the fan shaft to turn. The end of the chamber 24 adjacent the fan contains an opening 23 covered by pneumatically operated doors; the other end of the chamber 11 being constituted by a single door, 26. When the vessel is filled with gas all three doors are opened, and operation of the fan causes gas to flow through the chamber cooling the charges, and then past a cooling surface, as indicated by the arrows, so being cooled itself. The cooling surface in this embodiment consists of the surface of the vessel which is cooled by the passage of a cooling fluid between the double walls of the vessel and a system of pipes 32 cooled by the passage of cooling fluid through them.

[Class 38 (ii)] In an inverter comprising indirectly heated cathode valves, the cathode heaters 3 are supplied with two components of current, one derived from and proportional to the output voltage which tends to rise with decrease in load, and the other consisting of the whole or a fixed fraction of the load current to compensate for variations in the first. Fig. 1 shows a parallel-type inverter in which the first component is derived from a winding 9 on the output transformer 8 feeding the heaters 3 in series, whilst the second component is formed by the load current flowing through the two heaters in parallel. A resistance 11 may be connected to byepass a part of the load current. Fig. 2 shows the invention as applied to a series-type inverter.
