Abstract: An electronic tone ringer responds to ringing signals on a telephone line while being unresponsive to dialing pulses or other signals on the line. Powered directly from the telephone line the ringer uses current sources to provide a high impedance to the ringer circuitry and an insensitivity to line voltage variations so that reliable operation of the ringer is maintained on long loops and with multiple ringers terminated on the line. A multitone signal for activating an electroacoustic transducer (300) is provided by frequency modulating a single oscillator (500) within the tone ringer. Frequency stability of the oscillator is insured by the use of interrelated constant current sources that provide an insensitivity to supply voltage variations over a wide range. Two of the current sources determine the duty cycle by controlling the charge and discharge current of a capacitor in the circuit. A third current source determines the voltage swing on the capacitor. By varying the current output from the third current source, the generator circuit provides a variable frequency signal.

Abstract: The method is for joining concrete or other material with at least some permeability to water vapour. In the method the joint area is firstly cleaned mechanically or by compressed air from free water and dirt. The area is then subjected to several treatments with compressed air with regulation of air speed, vapour pressure and temp. so that optimal moisture evacuation occurs with the joint surface temp. remaining low. The steps are then repeated until the moisture no longer emerges. The joint surfaces are then heated to drive any residual moisture inwards, and the seam is constructed before the temp. drops to a level where moisture might re-emerge.

Abstract: The determn. circuit includes an adjustment device (22) for setting the required distance between laid mines, which activates a conversion circuit (14,16,18) which converts a path indicatory signal to a mine distance determining signal. A control circuit for receiving the mine distance determining signals, is coupled to a mine position indicator which passes appropriate signals indicative of the successive positions of a mine is the priming and feed-out stages. Manipulatory components fix, prime and feed out the mines under the action of the control circuit in a time sequence determined by the mine distance and position determining signals. The mine distance determining circuit is fed with voltage partly via a current switch (24) connected to the circuit components for provision of voltage to the laying process in the rest position, and partly via a spring-back press button switch (34). The latter allows current to be fed to the circuit so that the mine laying process may be initiated.

Abstract: In a deflection circuit, a flyback transformer and a retrace resonant circuit that includes a deflection winding are mutually coupled by a relatively small capacitor during the retrace interval so as to reduce transient distortions that may be caused by a sudden high beam current change. East-west modulation is provided to the deflection circuit output stage via an impedance having a relatively large value at the retrace frequency. A resonant circuit that includes the deflection winding and the flyback transformer is tuned to the retrace frequency. Synchronization information of the current through the deflection winding may be derived from a winding of the flyback transformer.

Abstract: A luminescent borate matrix has the general formula La, Y Eu<3+> (Mg, ZN)B5O10, wherein the lanthanum may be replaced in part or completely by yttrium and wherein the Eu<3+>, La/Y ions and Mg/ZN ions form linear arrays, the borate ions between then forming two-dimensional lattices in which La/Y ions and Eu<3+> ions are coordinated with 10 oxygen atoms, the Mg/Zn ions being located in an octahedron formed by 6 oxygen atoms, the matrix being activated by M<3+> activators in the place of La/Y ions and M<2+> activators in the place of Mg/Zn ions, M<3+> being Tb<3+> and possibly Gd<3+>, Ce<3+> and/or Bi<3+>, and M<2+> being Mn<2+> or Eu<2+>. Since mutual interaction and disturbance of the luminescent ions is minimal, it is possible to obtain several emission colours (e.g. blue, green and red using Eu<2+>, Tb<3+>, Eu<3+> and/or Mn<2+>). The material is therefore useful in low-pressure mercury lamps.

Abstract: The invention relates to a radar system comprising a transmitter with a periodically tunable HF-transmitter tube, as a magnetron with rotating tuning body, and a receiver with a mixing stage, in which echo pulses caused by transmitted radar pulses are mixed with the output signal from a local oscillator, whose frequency can be controlled. During transmission the tuning frequency of the transmitter tube is varied periodically and in an interval before triggering the local oscillator is "slaved" to the transmitter tube, so that the local oscillator frequency follows the variations in the tuning frequency. In the triggering moment the local oscillator is locked in frequency to the value prevailing in the triggering moment. According to the invention this system is combined with a frequency predicting circuit, which mainly consists of a comparator. In this comparator the control signal of the local oscillator, which due to the said "slaving" represents the instantaneous tuning frequency, is compared with a reference signal. The transmitter tube is triggered when the two compared signals are in a given relationship to each other, e.g. equal. Hereby, the transmitter tube is brought to produce a radar pulse having a predicted frequency, which is mainly determined by the said reference signal.
