Title: A radar system for measuring the speed of a target
Inventor: ROMANO VINCENZO
IPC: G01S13/524
Filed: 1966-12-22
Abstract: 1,136,809. Pulse doppler radar. SELENIAINDUSTRIE ELETTRONICHE ASSOCIATE S.p.A. 22 Dec., 1966, No. 57359/66. Heading H4D. Specification describes a pulse doppler radar of the type wherein the echo signals are frequency analysed by means of a coherent memory filter which produces an output pulse at a temporal position representing the doppler shift of the echo signal. With this simple arrangement however the maximum speed uniquely measurable is where frip = pulse repetition frequency f = carrier frequency. All higher speeds are ambiguously determined as an unknown multiple of Vo, plus an incremental measurable speed. The invention is to transmit alternate pulses with different but close carrier frequencies f1 and f2 and to determine the difference # in the temporal positions of the corresponding resulting output pulses from the coherent memory filter, whereby said difference represents an unambiguous velocity on the basis of a much larger uniquely measurable velocity The coherent memory filter comprises adding circuit #, Fig. 2, delays DLT and T each having a delay T equal to the repetition period of the transmitted pulse train, an amplifier K having an amplification determining the number of echo pulses which are summed and a mixer M whereby the frequency of the circulating input signal is shifted by the pulse repetition frequency. The echo signals 1 and 2 arising respectively from the transmitted pulses at frequencies f1 and f2 and occurring alternately are fed into adder # and the output 2<SP>1</SP> of the coherent memory filter from the echo pulses 2 are extracted from the output of the mixer. The output pulses 1<SP>1</SP> of the filter for the echo pulses 1 are extracted at the output of delay T by means of gate G, whereby for zero velocity the pulses 1<SP>1</SP> and 2<SP>1</SP> would be in phase. To determine #, pulses 1<SP>1</SP> and 2<SP>1</SP> are used respectively to start and stop a sawtooth voltage generator Go, whereby the output reached by Go represents # and the velocity. In case pulse 2<SP>1</SP> is missing generator Go is stopped by a pulse derived from a delayed 1<SP>1</SP> pulse. The output of Go may be fed to a range/velocity C.R.T. display.

Abstract: 576,472. Automatic control systems. HARDINGE CO., Inc. April 14, 1943, No. 5985. Convention date, April 23, 1942. [Class 38 (iv)] [Also in Group H] The proportion of large to small pieces of ore fed to a grinding-mill in which the ore is its lown grinding-medium is automatically regulated to secure optimum conditions of working by means which may include (1) a microphone responsive to the amplitude of sound emitted by the drum of the mill; (2) the power demand of the mill and classifier ; (3) the air pressure in the classifier circuit, and (4) the proportion of larger-sized material returned to the mill from the classifier. The bulk material is first graded according to size into two or more bins 4, 5, Fig. 2, which are discharged by conveyers 8, 9 driven by motors 11, 11<1>, the conveyers discharging in turn on to a conveyer 10 feeding the mill. The latter comprises a rotary drum 20, Fig. 1, fed axially, the product, removed by air blast generated by a fan 29, passing up a conduit 31 to a classifier. The fines pass through a conduit 33 to a separator 34, the air passing by a pipe 35 to the eye of the fan 29. The oversize pieces from the classifier pass down a pipe 37 to the drum intake. A vent stack 39 is provided and a portion of the air stream is passed through a pipe 41 to the bottom of the classifier to clear the oversize material. Fig. 9 shows the wiring - diagram. The microphone 45, which forms part of a sound-sensitive apparatus such as in Specification 505,177, is connected to a pair of switches 47, 48 connected with the control circuits 49, 50 of the feeder motors 11, 11<1> by means of which the rate of feed from the bins 4, 5 may be controlled. The automatic control may also be effected by a current-responsive relay connected with the circuit of the mill motor 24 or classified motor 30 by a doublethrow switch 55<1>. As shown in Fig. 8, the pointer 56 of a power meter is fitted with a double contact 57 lying between contacts 59, 59<1> on adjustable arms 58. The contacts 57 and 59 or 59<1> close the circuit to a thermal delay relay 61 whose contact points 61<1> are in series with the circuit of one or both of the feeder motors 11, 11<1>. The return of oversize to the mill from the classifier may also be used as the controlling agency. For this purpose the conduit 37, Fig. 7 is fitted with a pivoted shutter 381 carrying a mercury switch 65 operating through a switch 67 to control the feeder motors. Variation in the air pressure may also be the controlling agency through a U-tube 51 let into the return duct 35 ; excessive variation results in the liquid in the U-tube closing contacts thus effecting the control of the feeder motors through a relay 54. The material may be separated into more than two grades, in which case each bin is fitted with the electric control devices which are put into circuit by jacks.

Title: Improvements in or relating to multi-frequency control arrangements
IPC: B61L3/24
Filed: 1978-11-03
Abstract: In a failsafe arrangement of speed limit coding frequencies for an automatic train protection system, four frequencies f2-f5 representing the four lowest speed limits are grouped within one octave and further frequencies f0, f1 representing higher speed limits are located at lower frequencies so that faults producing harmonic interference are fail-safe since the lower speed frequency harmonics are outside the system bandwidth and the higher speed frequency harmonics are recognised as lower speed limits. Hitherto, coding frequencies have usually been relatively widely spaced at frequencies chosen to avoid mutual interference, and various system and practical constraints have limited the usable number of coding frequencies to three or four. <IMAGE>
