Title: Improvements in and connected with filling heads of liquid bottling machines
IPC: B67C3/28
Filed: 1937-10-14
Abstract: 503,927. Bottling. WORSSAM & SON, Ltd., G. J., and FOX, D. P. S. Oct. 14, 1937, No. 27987. [Class 125 (ii)] A filling head having a rotary valve operated automatically in step-by-step fashion comprises a valve 26 which is seated at the foot of the filling tube 19 and is positively opened by mechanical means associated with the rotary member 2 of the rotary valve. As shown, the mechanical means is an eccentric pin 31 on which is rotatably mounted a ring 32 which, when the plug is rotated, depresses a block 28, which carries the valve, against a spring 29. The ring 32 carries a pin 34 which, when the plug is moved to the " all-closed " position shown, pushes the float-valve 14 off its seating 13. For rotating the plug 2 there is provided a star wheel 5 having a square-holed hub 4 fitting over a squared part 7 of the plug. The plug has two right-angled passages 43, 44 spaced apart axially, the passage 44 terminating in a groove 45 on the face of the plug. In operation, the plug is turned, in four stages, through one complete revolution. First, counter pressure is established in the bottle by turning the plug through 90‹ from the position shown in Figs. 1 and 3 so that the two arms of the passage 43 connect passage 36, leading from the counterpressure tube 41, with a passage 35, 39 connected with an adapter tube 20. Then the plug is turned a further 90‹ so that (a) the passage 43 connects passage 35, 39 to a gas escape port 37 connected with a fob-return pipe, and (b) ring 32 depresses block 28 to admit liquid to the bottle. Next the plug is turned a further 90‹ so that passage 43 is closed and passage 44, which has hitherto been closed, now joins passage 35, 39 and a port 38 to apply an adjusted levelling pressure to the liquid in the bottle, as described in Specification 503,926. Finally the plug is turned to the position shown. When, during filling, a bottle or the rod 27 supporting the valve 26 breaks, the valve 14 stops flow of liquid.

Abstract: 1,224,879. Deflecting propulsive gases. ROLLS-ROYCE Ltd. 30 May, 1968 [17 June, 1967], No. 28031/67. Heading B7G. Movable deflecting means in a propulsion nozzle of a gas turbine engine either allow passage of propulsion gases rearward through the nozzle or direct the gases outwardly through one or more ducts in the wall of the nozzle; further deflecting means, mounted in or adjacent to the or each duct, being movable to give a component of thrust in a forward or rearward or intermediate direction. Two eyelid flaps are mounted in the propulsion nozzle 18, so that in position 24 the rearward flow of gases is unimpeded, while in position 26 the gases are caused to flow through ducts 20 in the wall of the nozzle 18. At the outer end of each duct are cascades 28, in the form of vanes 30 in a frame, the vanes in the forward half of the frame being inclined so as to direct the gases forward, while the rear vanes are inclined so as to direct the gases rearward. The cascades may be moved fore-and-aft by air motors 32 and screws 34, so that varying degrees of forward or rearward thrust may be obtained. In a further embodiment, Fig. 4 (not shown), fixed deflecting vanes are used, the direction of thrust depending on whether the forward or rearward facing vanes are exposed by a visor (38). In a further embodiment, Fig. 5 (not shown), the mouth of each duct is shaped so that when the forward portions of the duct are exposed by a pivoted visor (42) the gases flow forward, while exposure of the rear facing parts of the duct mouth causes gases to flow rearward. In a further embodiment, Fig. 6 (not shown), faired flaps, pivoted at the outer end of each duct, are used in place of vanes, the direction of thrust depending on the orientation of each flap relative to the flow of gases along its duct.

Patent GB-620318-A (GB)
Title: An improved failure indicator for gas-turbine engines
IPC: F01D21/06
Filed: 1946-09-25
Abstract: 620,318. Measuring vibrations. SHAW, H.W. Sept. 25, 1946, No. 28716. [Class 40 (i)] The invention relates to gas-turbine failure indicators of the kind wherein the engine vibrations are translated by a pick-up 14 into electrical oscillations, warning of impending mechanical failure being given by an increase in the amplitude of these oscillations as indicated upon a pointer instrument or oscillograph. According to the invention, the wanted oscillations, i.e. those due to the rotation of the compressor and turbine rotor 13, are separated from the unwanted oscillation by a thermionic valve discriminator 16 fed with a reference voltage from a generator 24 controlled from the engine shaft. The discriminator 16 is of known type wherein the engine-driven alternator output is connected through a transformer 23 in anti-phase to the anodes of respective triodes 18, 19, the grids of which are fed in phase with the pick-up oscillations after amplification at 15. When the reference frequency is equal to that of the wanted oscillations, the reading of the double-coil indicator 29 connected in the valve anode circuits will depend on the phase displacement between the discriminator input waves, and the phase of the reference voltage is adjusted, e.g. by manually rotating the stator of generator 24, until the reading is a maximum which is then regarded as corresponding to the normal amount of unbalance of the engine. Alternatively, the reference voltage frequency f1 may differ slightly from f that of the wanted oscillations, the alternator having its stator driven at a low constant speed, or being geared or otherwise locked to the engine shaft for this purpose. The beat oscillations at frequency ( f1- f ) are in this case arranged to be sufficiently low to be followed by the pointer of the indicator, the maximum value of the fluctuating reading being taken as the normal engine unbalance value. A peak-voltmeter may be used as indicator in this embodiment to give a steady reading. For example, the valve 19, Fig. 3, may be followed by a filter 31 to remove components at the frequencies f, f1 and higher orders, the beat frequency ( f1- f )being applied through a rectifier 33 to a D.C. voltmeter 34 having a relatively large time constant. A full-wave rectifier may be employed, Fig. 5 (not shown), and a further valve stage may be used between the rectifier and the meter, Fig. 4 (not shown), to preclude incorrect operation of the valve 19 due to the meter load thereon. When the pick-up 14 is of the variable inductance or capacitance type, the oscillations are produced by connecting the pick-up in an A.C. bridge or circuit 17 tuned to a medium radio frequency and excited from an oscillator at a frequency close thereto. The double-coil indicator 29, Fig. 1, may be replaced by a single coil meter connected across the anodes of valves 18, 19, Fig. 2 (not shown).
