Title: Method of transmitting speech by high frequency waves
IPC: H03C5/00
Filed: 1924-09-10
Abstract: 222,848. Habann, E. Oct. 2, 1923, [Convention date]. Heterodyne receiving systems.-In a system of speech transmission, an oscillation generator is used in which air waves of a frequency exceeding 4,000 act on a microphone or other vibratory body arranged to excite an electric oscillation circuit and the receiver comprises a similar device operating at a harmonic mechanical frequency other than a one to one relation to the frequency of the transmitter. The generator may be of the type described in Specification 190,577, in which speech is converted into sound-damped high frequency currents by mechanical high frequency interruption or ohmic, capacitative or inductive changes. A rectifier is unnecessary and the electrical connections at the receiving end are identical with the connections at the transmitting end. The Specification as open to inspection under Sect. 91 (3) (a) refers also to a receiver operating at a frequency equal to that of the transmitter. This subject-matter does not appear in the Specification as accepted.

Title: A new and improved process for forming metal annular members of high tensile strength
IPC: C22F1/00
Filed: 1923-08-31
Abstract: 225,913. Burnside, G. B. Aug. 31, 1923. No Patent granted (Sealing fee not paid). Rings.-Seamless metal annuli of high tensile strength are made by casting a ring of non- ferrous metal, e.g. copper, aluminium or copperaluminium alloy, in a metal mould' or die and then rolling or spinning the metal while it is maintained at a temperature of 500-800‹ C. When the ring is almost reduced to size, it is chilled by subjecting it to a cold air or water jet or by rotating it in a water bath. The rolling &c. is proceeded with during the chilling operation, to increase the tensile strength of the metal. The ring mav be annealed by rotating it immersed in a liquid bath maintained at the required temperature. The finished ring may be of flat, angular, or curved cross-section and may be formed with beads or grooves during the rolling &c. operations. The ring may be made in two distinct stages, the cast blank being first annealed and reduced between hot rolls and afterwards cold rolled to give the required high tensile strength. The rolling &c. may be carried out by hand tools or by power-driven rolls and the rolling pressure may be applied by hydraulic or screw agency.

Title: Method and apparatus for detecting imminent boiling
IPC: G21C17/038
Filed: 1964-05-27
Abstract: 1,064,662. Controlling reactors. M. MAROPIS. May 27, 1964 [May 27, 1963], No. 21984/64. Heading G6C. [Also in Division H4] A method for detecting imminent boiling in a liquid, e.g. in the water coolant of a nuclear reactor, comprises determining the ultrasonic power required to produce cavitation in the liquid. A vibratory probe 10 (Fig. 1) comprises a magnetostrictive, piezoelectric or other known type transmitting transducer 18 connected through a coupler 16 to a flexible acoustic waveguide 12. The waveguide 12 is sealed into, and acoustically insulated from, the wall 30 of a reactor pressure vessel by means of a tubular mounting 20, and the tip 14 of waveguide 12 is immersed in the liquid. Receiving transducers (28a, 28b) (Fig. 3, not shown), which may be barium titanate wafers, are mounted on the waveguide 12 at regions corresponding to adjacent nodes of the standing wave set up in the waveguide 12, and feed into band-pass amplifiers (54a and 54b). These amplifiers are tuned respectively to the fundamental frequency of vibration in the probe 10 and to a harmonic, or to two different harmonics. The power fed from a source (50a) to the transducer 18 is increased until cavitation sets in, this point being dependant upon the temperature and pressure of the liquid. The collapse of cavitation bubbles produces a noise spectrum giving rise to output signals from the amplifiers (54a and 54b). For automatic control of reactor power, these signals are combined by a unit (60) to provide a signal for feedback-type control of the power source (50a), a direct readout of transducer power being provided by a unit (64). In an alternative arrangement (Fig. 2, not shown), only one receiving transducer (28) is used and this feeds a spectrum analyser (56) with a visual (C.R.O.) indication of the harmonics, the power fed to the transducer 18 being indicated by a wattmeter (52). Constructional and dimensional details of the transducer 18 and the acoustic waveguide 12 are given. Provision may be made for cooling the transducers 18 and (28).

Abstract: 787,901. Automatic frequency control systems. GENERAL ELECTRIC CO., Ltd., and ROBINS, W. P. July 26, 1955 [July 28, 1954], No. 22106/54. Class 38 (4). In a klystron local oscillator frequency control system the frequency is swept over a search range by a motor operating mechanically on the resonator of the klystron, until an output from an I.F. amplifier of the receiver is obtained at an input 21 of a search stopping circuit 13 whereupon (1) a relay C1 operates by open-circuiting a control solenoid 40 to reduce the gear ratio and speed of the motor drive; (2) an electronic A.F.C. loop then stabilizes the oscillator frequency ; (3) the motor is alternately and continuously driven backwards and forwards to vary the tuning of the resonator of the klystron on either side of maximum power output under control exclusively by a hunting relay B/1; (4) the electronic A.F.C. continuously operates to counteract oscillator frequency variations which would otherwise arise due to the cyclic variation of the resonator tuning. Simultaneously with the relay C1 a relay A/1 also operates to reverse the electrical supply 35 input to the two-phase field coils 30, 31 of the motor through relay contacts B1 controlled by the hunting relay B/1. The hunting relay B/1 reverses the continuously running motor when any decrease of the local oscillator power output and hence D.C. output of the receiver mixer to the input 53 of the hunting relay circuit 12 exceeds a certain rate sufficient after amplifying in valves 50-52 to trigger a monostable circuit 54a, 54b. Output of the latter, differentiated by a capacitor 61, thereupon operates a bi-stable trigger circuit 65a, 65b to change over the relay B/1 and reverse the motor drive. The power responsive .hunting relay circuit 12 also continuously corrects for excessive frequency drift. Electronic control of the frequency is provided by the output of an A.F.C. discriminator being applied to a reflector electrode of the klystron. The motor control circuit 13 may be of the type described in Specification 750,132 employing an infinite impedance detector 22 and Miller integrator valve 24. The frequency control system may be applied to a radar transmitterreceiver.
