Title: Improvements in or relating to radio-echo distance measuring systems
IPC: G01S1/02
Filed: 1952-08-19
Abstract: 718,085. Radar. RAYTHEON MANUFACTURING CO Aug. 19, 1952 [Sept. 12, 1951], No. 20833/52. Class 40 (7) in a C.W. amplitude in frequency modulated radar the modulating signal is modulated by a reference signal of lower frequency and the transmitted and received reference signals are compared to distinguish true and spurious echo signals. The invention is described as applied to a frequency-modulated radar in which the amplitude or recurrence frequency of a triangular modulating waveform from generator 12 is modulated by a sinusoidal reference signal from oscillator 15, the resultant beat frequency produced by hetetodyning the transmitted and received signals in detector 20 being frequency modulated by the reference signal. The beat frequency is applied to a frequency discriminator 22 producing a D.C. control voltage modulated at the reference frequency which is applied via a servo amplifier 23 to so regulate the amplitude of the output from generator 12 that the average beat frequency is maintained at a predetermined value, the magnitude of the control voltage as indicated by meter 25 being dependent on the range of the target. The AC. component of the control voltage is applied to a phase comparator 26 together with the reference signal from oscillator 15 and when the two inputs to comparator 26 are of equal frequency and are in phase the comparator produces a D.C. voltage which actuates a relay 28 to extinguish a red warning light 34 and energize a green light 35 indicating the reception of a true signal. Alternatively the amplitude of the triangular modulating waveform may be constant in which case the D.C. output from discriminator 22 is proportional to range.

[Class 103 (i)] In a fluid pressure brake system, particularly for railways, of the type described in the parent Specification comprising a brake pipe, H, h, a regulating or triple valve RV, a quick inshot valve M, brake cylinder BZ, changeover locks U, auxiliary reservoir L, control reservoir S and accelerator unit B, there is also provided an equalizing valve unit AV, the purpose of which is to prevent communication between the reservoirs S and L being established during a release operation, before the pressure in the auxiliary reservoir L reaches nearly its normal value. Whereas in the parent Specification, this is brought about by brake pipe pressure acting in chamber 6, below the lower movable part of the valve unit AV, thereby exercising a controlling influence on the opening of valve 33, in the present invention the brake cylinder pressure is made to operate in the chamber 6. The movement of the valve member 2 to open the valve 33 depends on the upward force due to the brake cylinder pressure in chamber 6 and control reservoir pressure in chamber 7 opposed to the downward force exerted by the auxiliary reservoir pressure acting in chamber 9 and by spring 21 which is of such a strength that the valve 33 is not opened until the brake cylinder pressure has decreased below 0.4 kg./cm<SP>2</SP>.
