Title: Improvements in or relating to submarine mines
IPC: F42B22/10
Filed: 1922-11-08
Abstract: 210,873. Vickers, Ltd., and Elia, G. E. Nov. 8, 1922. Mines, marine. - Automatic mooring devices for submarine mines are provided with means for releasing the flotation chamber from the anchor when the complete mine, after launching, and during its descent, reaches a certain depth above that at which rupture of the flotation chamber is liable to take place, the mooring cable being then permitted to pay out at such a speed that the flotation chamber remains substantially at the same depth while the anchor sinks to the bottom. As shown in Fig. 1, the flotation chamber A is secured to the anchor B by links R, R<1> connected together by an hydrostatic device P, shown in detail in Fig. 4. At the appointed depth, the pressure of water admitted through holes p<1> to a diaphragm p depresses a spring plunger p<2>, unlocking balls s and releasing the link R. A timing device such as an hydrostatically-operated dash-pot or a soluble plug may be added to release the flotation chamber in shallow waters if the depth is insufficient to set the hydrostatic release in action. While the anchor sinks to the bottom, the speed at which the mooring cable is paid out of its drum C is checked by a screw-down valve d<1>in the circuit of a fluid pump brake D driven by gearing from the cable drum. After the anchor has reached the bottom, the piston d<5> of a dash-pot g withdraws a plunger d<4> from a bye-pass circuit of the pump brake, thereby reducing resistance and allowing the paying-out to proceed more rapidly. The piston d' is urged upwards by pressure of water admitted beneath it, and its rise is controlled by the flow of oil from the dash-pot g to a chamber h through a ball valve j. In a modification, the cable drum drives two separate brake pumps until after the anchor reaches the bottom, when a dashpot device uncouples one of the brake pumps, thereby reducing the resistance as desired. Other types of fluid-resistance brakes or frictional brakes may be used, and a simple hydrostat or a soluble plug may be used instead of the above device. The flotation chamber is finally stopped and held at the desired depth by any suitable means, for example as described in Specifications 163,339 and 211,196.

Title: Improvements in or relating to radio beacon systems
IPC: G01S1/02
Filed: 1945-11-19
Abstract: 601,641. Directive radio systems. SADIRCARPENTIER. Nov. 19, 1945, No. 31093. Convention date, Oct. 18, 1943. [Class 40 (vii)] A radio beacon system radiates two highfrequency fields, one omni-directionally and the other directionally, both fields being modulated by two low-frequencies, the relative phase in one case being reversed with respect to the relative phase in the other case so that a courseline is defined by the predetermined fixed direction in which the separate modulation intensities of the combined signal are equal. A radio-frequency oscillator 1 generates a signal which is modulated at 4 and 5 by the signals of frequency f and f2 generated by lowfrequency oscillators 2 and 3 respectively. The modulator outputs are added together and transmitted from omni-directional aerial A, the field radiated having the form : The signal from oscillator 1 is also changed in phase by 90 degrees in unit 7 and modulated with frequencies f and f 2 in carrier-suppression modulators 9 and 8, the side bands (which are combined in an opposite sense to that obtaining at A) being radiated from the loop aerial B, which thus radiates a signal of the form where f (#) expresses the directive properties of the aerial. The receiver comprises a highfrequency amplifier and detector feeding two amplifiers in parallel, one tuned to f1 and the other to f2 so that signals are obtained depending upon the amplitude of each modulation component of the combined field. In the case illustrated, the condition that the receiver outputs shall be equal is expressed by f (#)=0 which consequently defines the course-line. It is not necessary that both radiated signals be modulated equally by both low-frequency signals. If different intensities of modulation are used, another course line will be defined by the relation f(#)=const., so that by varying the intensities of modulation the beam direction may be varied.
