Abstract: 405,932. Rectifying alternating current. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.- (Assignees of Allgemeine Elektricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) Oct. 16, 1933. No. 28610. Convention date, Oct. 14, 1932. [Class 38 (ii).] In a rectifying arrangement in which a grid-controlled rectifier 10 feeds a load circuit such as the anode circuits of a valve transmitter 14, 15 having in parallel therewith a condenser 12, a spark gap 13 is connected across the condenser and is arranged to be broken down in the event of short-circuit conditions arising in the load circuit so as to divert the discharge of the condenser from the load circuit. The provision for breakng down the spark gap may comprise auxiliary condensers 26, 27 connected in series with the primaries of transformers 28, 29 across the transmitter valves so that, should either of the latter fail, discharge of the auxiliary condensers through the faulty valve will induce in the secondary of the corresponding transformer a voltage sufficient to start a discharge between an auxiliary electrode 31 and the upper main electrode of the gap 13. Provision may also be made for short-circuiting the cathode inductance 22, such provision comprising additional secondaries 38, 39 associated with the transformers 28, 29 and adapted to neutralize the blocking bias normally applied to the grid associated with an auxiliary anode 23 in the rectifier 10. Further, provision may be made for stopping the rectifier 10, such provision comprising a further pair of secondaries 36, 37 associated with the transformers 28, 29 and adapted to neutralize the blocking bias normally applied by a battery 34 to the grid of a valve 21 thus causing negative voltage from a battery 20 to be applied to the grids associated with the main anodes of the rectifier 10. In an alternative arrangement, Fig. 2 (not shown), the voltage drop in a choke inserted between the condenser 12 and the transmitter valve 14 is utilized to break down the gap 13 and to neutralize a blocking potential in a valve connected across the inductance 22 in the event of short-circuit conditions arising in the load circuit. Specification 403,922 is referred to.

IPC: H03L7/02
Filed: 1947-10-30
Abstract: 645,706. Calibrating oscillators condensers. STANDARD TELEPHONES & CABLES, Ltd. Oct. 30, 1947, No. 28973. [Class 37] [Also in Group XL (c)] In an oscillation generator having a continuously adjustable element for controlling the frequency and a standardized scale, an auxiliary adjustable condenser is associated with an oscillation circuit of the generator and coupled to the continuously adjustable element for simultaneous adjustment therewith, the capacity of the auxiliary condenser being so proportioned as substantially to ensure correspondence between the frequency generated and the frequency indicated on the scale. As shown in Figs. 3 and 4, a precision oscillator of the type in which the outputs of a fixed and variable oscillator are combined and the lower sideband selected, is provided with a variable condenser 6 having a shaft 7 carrying a radial arm 8 the end of which is bent at right angles to form a member 9. A semi-circular plate 10 of cylindrical form is fixed co-axially with the shaft 7 and co-operates with the member 9 to form a small condenser, the capacity being dependent on the shape of the edge of the plate 10. This may be determined by connecting in parallel with the condenser 6 a small calibrated variable air condenser, the auxiliary condenser being disconnected, and determining at a number of points in the scale of the oscillator the capacity to be added to produce the correct frequency. Alternatively as in Fig. 5, the outputs of the oscillator under test 18 and a reference oscillator 19 of identical type, are combined in a modulator 20 from which the difference frequency is extracted and applied to a frequency discriminator. This supplies an output proportional to the frequency error to the coil 22 of a recording instrument, the variation being traced on a strip of paper mounted on a drum 24, and the paper used as a template to shape the plate 10. The shaft 25 of the drum is coupled mechanically or electrically to the shaft of the variable condenser of the oscillator 19 to ensure accurate correspondence between the positions of the two shafts the oscillator 18 being preferably coupled in the same way, and an adjustable resistance 26 is shunted across the coil 22 with its movable contact carried by the shaft 25, the law of variation of the resistance being arranged so that the output is converted into the correponding capacity error. The standardized scale may be a strip of kinematograph film carrying the desired graduations or alternatively as in Fig. 4 a disc 11 of transparent material bearing a scale around the periphery is rigidly fixed to the shaft 7 provided with an adjusting knob 13, and a light source 16 projects a beam of light through the disc 11, a lens system 17 projecting a magnified image of the scale on the ground glass window 14 in the panel.
