Filed: 2006-04-27
Abstract: A resonator is provided with a tuning element based on piezoelectricity. The piezoelectric basic element includes at least one piezoelectric layer and a metal layer. Such a basic element is first coated with a thin insulating layer and then with a good conductor. The thickness of the conductive coating is greater than the skin depth of a field corresponding to the operating frequency of the structure in the conductor. The tuning element formed in this manner is fastened on, e.g., some inner surface of the resonator cavity and acts to change the natural frequency of the resonator by electric control. When using the tuning element, no mechanical arrangement is required for moving the tuning element. Furthermore, the tuning element does not cause considerable dielectric losses nor intermodulation when being in a radiofrequency electromagnetic field, because the field cannot significantly penetrate through said conductive coating into the piezoelectric material.

IPC: H02M1/06
Abstract: 1,051,629. Rectifying. MULLARD Ltd. Oct. 21, 1964, No. 42889/64. Heading H2F. [Also in Division G3] A D.C. supply is derived from an A.C. source by way of a rectifier 2, a filter 3, a chopper circuit 4, and a smoothing circuit 8, the output voltage being automatically stabilized by correctively varying the trigger rate of the chopper circuit 4 which includes a load thyristor 10 and a commutating thyristor 11 associated with a commutating capacitor 12, a diode 14, an inductor 13 and resistors 15, 16. The smoothing circuit 8 comprises an inductor 17, a capacitor 18 and a free-wheeling diode 19 connected to be non-conducting when the thyristor 10 is conducting. On heavy load, when thyristor 11 is triggered on to turn off thyristor 10, the induced E.M.F. across inductor 17 is of such polarity as to force diode 19 to conduct. This holds the cathode potential of thyristor 10 at earth potential, allowing the thyristor to turn off rapidly and preventing commutation failure due to lack of reverse bias on thyristor 10 for a sufficient period.

In an incinerator plant, steam generated in the water-cooled walls of the refuse burning furnace is used to drive a pump circulating the cooling water, a forced draught fan and an induced draught fan, any excess steam being disposed of in a condenser. The combustion air may be preheated by steam. The pump and fans are electrically driven for starting up, and as the steam pressure rises, the steam passes through the air preheater, and steam turbines operating the water pump, the forced draught fan and the induced draught fan are energized in that order. The switch over from electric drive to steam drive may be manual or automatic. Low pressure steam from the turbines is passed through an air preheater, and excess steam is condensed in an air-cooled heat exchanger, the condensate being returned to the de-aerator and supply tank. High pressure steam in excess of requirements may be passed to separate air-cooled condenser, and the plant may be arranged to supply export steam.

Abstract: 1,250,667. Automatic steering control. AMERICAN CHAIN & CABLE CO. Inc. Jan.3, 1969 [Jan. 8, 1968], No.428/69. Heading G3R. In a system for automatically steering a vehicle along a course defined by a buried leader cable carrying A. C., deviations are detected by pairs of coils with their axes horizontal on each side of the vehicle, one coil of each pair being connected together in series and the other coils connected together in parallel. In Fig.7, a pair of coils 19 arranged with their axes horizontal, one on each side of the centre-line of a steerable wheel of a vehicle, are connected in parallel opposition so that an error signal representing deviation of the path of the vehicle relative to a buried cable carrying A. C. is applied through an amplifier 26 to a phase sense sensitive detector 27. A further pair of coils 20 also arranged with their axes horizontal, one on each side of the centre-line, but connected in series addition, produces a reference signal for detector 27 which produces a D. C. signal the magnitude and polarity of which corresponds to the magnitude and sense of the deviation. This signal is modulated at the reference frequency by a chopper 30, amplified at 31, 32, and applied with the reference signal to a phase sense sensitive detector 33 the output of which, through a transistor power amplifier, causes operation of a steering motor 14 in the appropriate direction to correct the deviation from course. The magnitude of pulses from amplifier 31, rectified at 35, determines the frequency of a pulse generator 36 which controls gates 37, 38 so that the steering motor 14 is operated intermittently at a rate which decreases with decrease of error. Stabilizing feedback is applied from a tachometer generator coupled to steering motor 14, from the output of the power amplifier supplying motor 14, and from the output of rectifier 35.
