Title: Improvements in radio signal receiver
IPC: H03J7/32
Filed: 1944-06-29
Abstract: 585,723. Wireless receiving systems. AUTO-ORDNANCE CORPORATION. June 29, 1944, No. 12401. Convention date, July 20, 1943. [Class 40 (v)] A double panoramic receiver is arranged to give two adjacent traces on the same cathoderay tube. A receiving aerial 25 is connected to the grid of an R.F. amplifier 26, having a variable'tuning circuit 12, 14, and to the grid of a second R.F. amplifier 27, having a variable tuning circuit 13, 15, the outputs from both amplifiers being fed to an I.F. amplifier 30, detector 31 and a video amplifier 32, the output from which is fed' to the vertical deflecting plates 37 and grid 34 of a cathode-ray tube 35. A shaft 10, driven by a constant speed motor 11, drives a commutator 16, which effects the energisation of the amplifiers 26, 27 during alternate half revolutions, and also tunes the circuits 12, 14, and 13, 15 through complementary frequency ranges. The shaft also rotates a two-ended contact 19 so as to engage contact 20 twice per revolution to connect the H.T. source through a time constant circuit 39 to the horizontal deflecting plates 40 of the cathode-ray tube, thus providing two saw-tooth scanning pulses per revolution. The vertical deflecting plates 37 are also connected to a potentiometer 42, part of which is short circuited during one half revolution by a rotating contact arm 21, driven by shaft 10. By this means the traces A, B occurring during alternate half revolutions are displaced vertically and correspond to the periods of energisation of the receivers 26, 27 respectively. Signals received on each receiver produce vertical deflections on the corresponding traces thus indicating on a common tube the presence of frequency of transmissions over a wide frequency range. As the video output is also fed to the grid 34, the indications are also increased in brightness. The shaft 10 also carries a dial 46 for use in manually tuning the apparatus to a desired transmission after its presence has been detected by the motordriven scanning arrangement, a loud speaker being then connected to the output of video amplifier 32.

Title: Improvements in electrically driven pendulums for clocks
IPC: G04C3/027
Filed: 1936-05-04
Abstract: 474,454. Photo electric control of clocks. JONES, O. C. May 4, 1936, No. 12525. [Class 40 (iii)] [Also in Group XVIII] In an electric clock with an electromagnet b for re-energizing the pendulum a by direct magnetic attraction the circuit of the electromagnet is so controlled by a delay action relay h that an impulse is given to the pendulum only on one side of the zero position and as the pendulum is approaching the magnet. The relay h is provided with a metal sleeve h<1> and/or may be short circuited by a con-' denser i so that the de-energization, but not the energization, of the relay is delayed. Thereby the closing but not the opening, (at contacts cl) of the circuit of the electromagnet is delayed. The bob a carries a soft iron armature a<1> for coaction with the electromagnet b and a shutter e which cuts a beam of light f at each swing of the pendulum. The beam is just to the left of the zero position of the pendulum and normally causes the photo-electric cell and amplifier g to close the contact g<1> which energizes the relay h. The armature of the latter is thereby normally rocked counterclockwise to hold contact c<1> open. When the shutter e cuts the beam f, contacts g<1> open and relay h commences to de-energize under the delaying action of the sleeve h<1> or of the condenser i and close contacts c<1> which energize electromagnet b. Assuming the pendulum is swinging from right to left, the above cutting of the beam would cause an attraction at once between magnet b and armature a<1> as the pendulum is moving away from the magnet but by the time deenergization of relay h is complete, the pendulum has commenced its swing to the right and the attraction by magnet b, now energized, increases as the pendulum approaches it until at about mid-swing the circuit d is again closed. If the pendulum, through excess amplitude, swings so far to the left that the shutter e uncovers the beam f on its right, the relay h is re-energized without delay so that contacts c<1> are held open whilst the pendulum is swinging to the right. This goes on until the amplitude is reduced to normal. To enable the pendulum to be started in vacuo a switch j is provided to close the circuit c manually.
