Filed: 1971-09-08
Abstract: 1369615 Bottling &c using counter-pressure SIMONAZZI A & L SpA 8 Sept 1971 41823/71 Heading B8T In an automatic container filling apparatus, the container is raised on a jack into a bell 10 and is sealed to a valve assembly body 1 by a rubber ring 25. Bell 10 carries a pusher member 20 with an abutment 19 which engages on pin 11 and operates push rod 12, thereby actuating member 14 to open gas valve 16 and allow gas in chamber 26 to flow through grooves 27 and bore 39 into the container. When the gas pressures in chamber 26 and the container are equalized, spring 18 raises valve element 22 and opens liquid valve 17 allowing the container to fill from liquid chamber (41), Fig. 5 (not shown), through duct (48) and chamber 36, the gas returning to chamber 26 through bore 39, grooves 27 and valve 16.  In its upward movement, push rod 12 also opens 3-way valve 4, supplying compressed air from manifold (3) to the upper cylinder 5, and causes piston 7 to be lowered, overcoming the reaction of spring 6, and pushes probe 9 carried on stem 8 into the container. When the liquid reaches the bottom of probe 9, an electrical impulse is transmitted to a valve (30) which admits air into a chamber 24 displacing a piston 21 which displaces pin 11 off abutment 19 and allows push rod 12 to fall under the action of spring 13, thus closing valve 16 via member 14. The fall of rod 12 also actuates the 3-way switch 4 allowing chamber 5 to exhaust to atmosphere and permitting spring 6 to raise piston 7 and remove the probe 9 from the container, which is vented to atmosphere via holes 31, 32 by the continuing movement of piston 21. An over ride button (40) integral with piston 21, Fig. 4 (not shown), is incorporated in the event of failure of the electrical valve (30) to operate.

Abstract: 1,212,046. Radar. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 10 Sept.; 1968 [11 Sept., 1967], No. 43009/68. Heading H4D. Relates to the kind of F.M.C.W. radar altimeter in which a triangular F.M. wave from an oscillator 14 has its period T controlled to be proportional to echo time T, the beat frequency fb from a balanced mixer 30 being compared with a reference frequency f 0  to produce an error signal which controls period T such that fb = f 0 . According to the invention the amplitude S of the triangular wave is corrected during a calibration operation involving a constant delay in a line 102. In the embodiment the control of period T is effected from a non- linear device 74 and of amplitude S, by pulses from a discriminator 10. The beat frequency signal fb of approximately 25 kc/s. from mixer 30 (proportional to 2S#/T) is passed via a highpass filter 32 to a wide-band amplifier 34 to maintain the brevity of short parasitic pulses which are reduced by a clipper 36. The ensuing signals are fed to a band-pass filter 40 centred on 25 kc/s. and thence via a clipper 42, reducing signals to the noise level, to filters 56, 66 of respective pass-bands 15 to 25 kc/s. and 25 to 35 kc/s.; the filter outputs are passed to a difference detector 52 and by way of a normally closed switch 54, a saturated amplifier 58, and an integrator 60, 62 (switch 64 being normally closed and switch 72 being normally open) to the non-linear circuit 74 which produces an output voltage P = P 0  exp (Ca/f 0 ) where P 0 , C are constants and a is the input voltage. The output of clipper 42 also feeds filters 46, 48 of respective pass-bands 22 to 28 kc/s. and 28 to 34 kc/s.; a comparator 44 energizes a logic circuit 50 (having a delay of half a second) for giving an alarm and for initiating a " search " operation if the signal spectrum is not centred on 25 kc/s. Pulses from discriminator 10 are standardized by a circuit 84 to a constant duration d and the circuit 76 measures the value T/d, meter 80 indicating altitude; a duplicate 78 of circuit 76 is provided, a comparator 82 raising an alarm if their outputs differ. During checking periods a switch 94 is opened to avoid disturbance of the meter reading; the transmitted signal is mixed with a signal via delay line 102; switches 54 and 64 are opened; switch 72 is closed to insert the voltage on capacitor 70 stored during preceding checking periods; switch 54 is closed shortly after being opened; a switch 98 is closed to bring into circuit a voltage comparator 114, any deviation from a standard voltage acting on the control of amplitude S to maintain it constant. The alarm system is actuated if the deviation is greater than a predetermined amount.
