Patent GB-2181821-A (GB)
Title: Air dump valves
Inventor: MORRISON BRIAN
IPC: F16K11/048
Filed: 1986-10-16
Abstract: An electro-pneumatic dump valve comprises an aluminium main body 12 section 2 and an aluminium block 3, a solenoid operated pilot valve assembly 4 being mounted to the former. Outlet 8 supplies pneumatic power to a remote machine and communicates to a main valve cavity 10 in which a valve shuttle 11 comprising poppets 13, 14 and associated cruciform connecting rod 12 is disposed for reciprocatory displacement. Input of air with poppet 13 seated and solenoid 31 activated produces a pressure differential between cavities 18 and 10 which urges the poppet into secure sealing seating. A bleed stream of air passes from cavity 18 via orifice 17 and bleed conduit 20 to pressure cavity 19, the pressure in the latter rapidly reaching the point where its force on poppet 14 balances the downward force on poppet 13. The seal of poppet 13 is then broken by the maintained pressure differential between cavities 10 and 18 to connect the air supply via cavities 10 and 18 to outlet 8. Poppet 14 is in this condition seated to isolate outlet 8 from exhaust 22. De-energization of solenoid 31 allows pressure in cavity 19 to act through solenoid conduit 29 on sealing disc 39 of the solenoid to open the solenoid outlet orifice 40 to atmosphere. This exhaust air and allows unseating of poppet 14 (and thus seating of poppet 13) which has the dual effect of shutting off air supply to cavity 10 from inlet 42 and of allowing entry of machine air by reverse flow back into cavity 10 via outlet 8 and its exhaust through exhaust outlet 22. <IMAGE>

Title: Radar.
Inventor: VOLES ROGER
IPC: G01S7/282
Filed: 1987-03-27
Abstract: To provide stationary or mobile radar with the capability of measuring the true range profile, a radar system includes a voltage controlled oscillator 10 coupled to a duplexer 11 via a pulse modulation circuit 12. A digital control circuit 13 provides a sweeping 500 Mhz frequency (F) of 6N successive batches of M pulses being incremented in steps of <F>/6N. Oversampling at a ratio m, enables "pure" spectra to be dissected from "hybrid" spectra. Returns received in response to each transmitted pulse are then combined in mixing circuit 14 with the signal from local oscillator 15 to generate a signal IF; at a circuit 22, each signal is summed with signals for the same range cell derived from earlier pulses transmitted at the same frequency; thereafter the signals pass through a FFT circuit 23. To maintain the "dissected" spectrum centred at the 2N<th> range cell, respective summations are carried out in two circuits 24, 25 and then differenced in circuit 26 and normalized in circuit 27 by the total signal energy present in the true profile range obtained from summing circuit 28, the output therefrom providing an error signal whose magnitude and sign are used in circuit 29 to estimate any change required in the value of prf, fr, thereby to achieve the value of T which will maintain the dissected spectrum centred on the 2N<th> range cell. <IMAGE>
