Title: Improvements in or relating to valves of the travelling wave type
IPC: H01J23/065
Filed: 1952-09-30
Abstract: 746,753. Travelling wave tubes. TELEFUNKEN GES., [formerly TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE]. Sept. 30, 1952 [Oct. 1, 1951], No. 24410/52. Class 39 (1). In a travelling wave tube supporting means for the gun electrodes project from one side of support member 1 and tube 3 in which the helix 4 is located extends from the opposite side of member 1, the member 1 extending perpendicular to the tube axis, and the gun and its supports are enclosed in a tube envelope portion 14 which may be formed in part by common supporting member 1. In one form metal rods 2 serving as gun supports and leads are sealed through glass or ceramic envelope base 1. They may be spaced unequally around a circle, rod 2 connected to helix 4 in particular being widely spaced from the other rods. Glass envelope portion 3 which is in contact with the helix 4 directly or through intermediate angularly spaced insulating strips is sealed to base 1 using a jig to make it accurately concentric with the circle of rods 2 and with its axis parallel to rods 2. The gun electrodes comprising indirectly heated cathode 7, wehnelt cylinder 6 and anode 5 are assembled as a unitary structure by ceramic supports 9, 10 and mica member 11 mounted on three supporting rods 12, and this structure is then threaded over three rods 2 and attached thereto by eyelets 13. Alternatively rods 12 may be dispensed with and the insulating members 9-11 assembled directly on to rods 2, but this is not preferred. The assembly can be precision checked by shining a beam of light through a hole in the centre of cathode 7 along the axis of the system. After final adjustments the envelope is completed by sealing glass, ceramic or metal bulb 14 to base 1 at 15, the device is evacuated and sealed off at 16. In a modification operating with an external coil or magnet for focusing a high-beam current, supporting members 2 are secured to base 1 but do not pass through it, and separate current leads to electrodes 4-7 are taken through the envelope portion near the cathode. If base 1 is of metal, a similar construction is used to the latter case, separate current leads being taken through a glass base at the upper end of 14. In another modification, rods 2 are dispensed with and the gun structure carried on rods 12 is mounted by securing ceramic member 9 to an accurately ground part of the metal base 1 or to an accurately ground intermediate member mounted on the base. The helix may be replaced by any other form of retardation line.

A power-driven tool for installing a wire-coil insert in a tapped hole comprises a tubular housing 10, a rotatable drive sleeve 17, a hollow prewinder body 16 releasably connected to the housing 10 and including an interiorly threaded prewinder foot 34, a nut portion 38 of the same pitch as the thread of the foot 34 and a charging chamber 37, a mandrel 35 being axially shiftable in the sleeve 17 and projectable with its slotted front end through the foot 34. The mandrel has a head 24 permanently connected to the driving sleeve for common rotation and has an external screw thread 30 at its driving end to receive an insert, the mandrel being helically guided in the nut 38 throughout its movement. The threads of the nut 38 are one half pitch out of phase with the thread of the prewinder foot 34, so that the inner threadforming part of the insert passing through the prewinder foot is in lead with the thread of the nut. The housing 10 and sleeve 17 which is journalled in a needle bearing 18 are connected respectively to the stator and rotor of a reversible prime mover e.g. an air motor which automatically stops rotation when a predetermined load is exceeded. A rubber bumper 27 is located on the drive shaft 19 between the coupling element 21 and the mandrel head 24. An interchangeable spacer ring 44 on the shank of the mandrel limits the distance the mandrel can project. The thread of the nut portion 38 is formed by an insert 40 of the type to be inserted in a workpiece by the aid of the tool. The slot 32 at the end of the mandrel 23 extends part way across the end face 31 which has an apex providing slopes permitting the mandrel to become disengaged from the insert after installation, on return movement of the mandrel.

Abstract: 1,073,552. Automatic frequency control systems. MULLARD Ltd. June 14, 1965, No. 25122/65. Heading H3A. In a system for synchronizing a local oscillator with a reference signal, voltages corresponding to the reference signal and the local oscillator signal are compared in a differencing circuit, the output of which controls the frequency of the local oscillator. First, the A.C. reference signal is applied to a frequency discriminator which produces two D.C. voltages corresponding respectively to the quadrature components of the input and which are received in separate stores. Next, the A.C. output from the local oscillator is applied to the same frequency discriminator and the further D.C. voltages are produced corresponding respectively to the quadrature components of local oscillator signal. Both sets of D.C. voltages are now applied simultaneously to two multipliers the outputs of which are taken to a differencing circuit the output of which is proportional to the difference in frequency between the local and reference signals. In a further embodiment, two parallel systems of the above type provide respectively coarse and fine control of the local oscillator frequency. A further development dispenses with the storage arrangements.
