Title: Fuel control system for a gas turbine engine
Inventor: EAMES KEITH
IPC: G01M15/00
Filed: 1966-02-23
Abstract: 1,135,614. Gas turbine engine fuel systems. ROLLS-ROYCE Ltd. Feb. 16, 1967 [Feb. 23, 1966], No. 7874/66. Heading F1G. [Also in Division G1] A fuel control system for a gas turbine engine comprises computing means connected to receive at least one input signal which is functionally related to the ambient conditions to which the engine is subjected, and a second signal which is functionally dependent on a selectable mode of operation of the engine. The computing means is adapted to calculate from the value of the at least one input signal and the second signal, a required value of an engine operating parameter and to provide a first output signal which is functionally dependent thereupon, the required value being that necessary to achieve the selected mode of operation of the engine. The engine shown comprises a fuel system 20 comprising fuel tank 21, pump 22 and control unit 23 which receives a signal through line 35 from the fuel control system 34 which is shown in Fig.2. Sensing devices 17, 18, 19 are mounted on the aircraft and the resulting signals which indicate total temperature and total pressure of the ambient air and aircraft Mach number respectively are fed through transducers 37, 38, 39 and change-over device 48 to computer 40. Engine jet pipe total pressure is sensed at 25 and signals therefrom are fed through inlets 33 into the system 34. A signal indicative of the desired mode of operation of the engine is fed from the selector 58 to the computer 40 and the computer calculates from the various inputs the required jet pipe total pressure this signal appearing at 60 and being fed to a pressure balancing means 70 also to a gauge 77. The signals of jet pipe total pressure at 33 pass to a device 62 which supplies an output at 64 indicative of the average value of jet pipe total pressure to a transducer 66, the signal from which passes at 68 to the pressure balancing means 70 and another signal from which passes at 76 to the gauge 77. The output from the pressure balancing means 70 at 74 is an error or out-of-balance signal which is fed at 35 to the fuel control unit 23. The values of ambient temperature and pressure may initially be supplied manually to a device 52, the signals from which pass at 44, 45 to the computer 40. The gauge 77 gives a visual indication of the difference between computed and measured jet pipe total pressures; an output 78 from the gauge 77 may be fed to a data recorder.

Patent GB-892831-A (GB)
Title: Rapid fire gun
IPC: F41A19/58
Filed: 1954-03-18
Abstract: 892,831. Automatic guns. MARQUARDT, F. R. March 18, 1954, No. 7983/54. Class 92. In a rapid fire gun having two barrels, the revolving breech and cartridge belt feed are operated by the recoil. The rounds are inserted into the breech and the cartridge cases ejected by gas pressure. The firing chambers are cooled by carbon dioxide gas. Firing, which is effected electrically, has a rate which is determined either by the rate of mechanical cycling of the gun or by an adjustable timer. To charge or load the gun initially, the mechanism is given a displacement equivalent to that produced by a single round by a plunger and cylinder system supplied from a compressed gas tank, the pressure in which is maintained by the explosion gas from the barrels. As shown, Fig. 3, the frame 42, barrels 40, 41 and breech 55 move to the right upon firing. Shaft 62 is fixed relatively to 42 and hence the arm 61 is rotated anticlockwise so that its upper end moves to the left and by means of link 60 and cam 56 causes rotation of the breech 50 about the gun axis. Simultaneously, the ammunition feed sprocket 82 is rotated and as shown, Fig. 6, each round is ejected from tube 83 by an explosion initiated by the electrically fired primer 85. The round is propelled into the firing chamber 53 of breech 50 which is then rotated into the firing position, in line with a barrel. In this position, the cartridge is fired by an electrical contact device (not shown) and the subsequent recoil and movement of 42 repeats the cycle. The rotary energy of the breech is transmitted back to the breech by means of link 60 and cam 56 to give it a forward motion which tends to absorb the recoil energy of the next round fired. To charge the gun, high pressure gas from tank 128 is admitted to chamber 140 by control valve 133 and forces 42 to slide to the right with an impulse equivalent to that of a single round. Tank 128 is initially charged to the required pressure and is maintained at that pressure, by the explosion gases of the rounds fired, by means of valves 128b. The ejection of cartridge cases is effected by high pressure gas from tank 128 which passes into the front end of the firming chambers through tubes 156. The latter are mounted on the frame 42 and when the reciprocation of the latter brings the openings 155 and 170 into registry the cartridge cases 157 are forced back into the carrying tube 83.

Title: Dialkenyl arylphosphonates and polymers thereof
IPC: C07F9/40
Filed: 1948-03-17
Abstract: Diesters of aryl phosphonic acids with b :g -mono-olefinic monohydric alcohols, e.g. diallyl phenyl phosphonate, are polymerized to fire-resistant resins by means of heat and (or) light, optionally in the presence of a polymerization catalyst, e.g. an organic peroxide such as benzoyl peroxide, a hydroperoxide, e.g. tert.-butyl peroxide, peracetic acid, an inorganic per-salt, ozone or oxygen.  The aryl radical in the aryl phosphonic acid is usually phenyl which may be substituted by benzyl or lower alkyl groups, and the olefinic radical in the ester may be methallyl, crotyl, tiglyl, cinnamyl, furfuryl, chloroallyl, bromoallyl, 2-hexenyl, or 2-decenyl.  Many such esters are specified.  The esters polymerize in stages, from a soluble to an insoluble thermoplastic resin and then to the thermosetting final product.  The esters may be polymerized in presence of dyes, pigments or fillers.  The esters may be co-polymerized with, for example, styrene, methylstyrene, 1 : 3-butadiene, cyclopentadiene, vinyl or allyl acetate, diallyl phthalate, methyl or ethyl acrylate, diallyl diglycolate, crotyl stearate, methyl vinyl ketone, methyl isopropenyl ketone, acrolein, methacrolein and acrylonitrile.  Mixtures of the above p  and mixtures of the phosphonates may be used.ALSO:Diesters of aryl phosphonic acids are prepared by reacting b : g -mono-olefinic monohydric alcohols with aryl phosphonyl dihalides, e.g. dichloride, preferably in presence of an acid-binding compound such as an organic amine, e.g. pyridine, or an inorganic base, e.g. sodium hydroxide.  The temperature is preferably 0 DEG  C. or lower, and an inert solvent, e.g. toluene, is employed.  Preferably the aryl part contains no more than 9, and the alcohol no more than 10 carbon atoms.  Specified aryl groups are phenyl groups substituted by methyl, ethyl, isopropyl and benzyl groups.  Allyl alcohol is preferred but others specified include methallyl, crotyl, tiglyl, cinnamyl, furfuryl, chloroallyl and bromoallyl alcohols, also 2-hexenol, 2-octenol and 2-decenol. The esters may be isolated without distillation by washing with an aqueous base.  A polymerization inhibitor, e.g. tannic acid, is preferably present during the reaction.  In an example, diallyl phenylphosphonate is prepared by treating allyl alcohol and pyridine with phenyl phosphonyl dichloride in toluene at -35 DEG  C. and then at 0 DEG  C.

Filed: 1925-03-25
Abstract: 239,129. Rossi, F. Scribani-, and Bombrini Parodi-Delfino. March 25, 1925. Projectiles; projectile fuzes. -A grenade is made with two inner explosive charges 3, 4 within an outer casing 1 with conical ends, so that, on impact in any direction, the explosive charges, which are normally kept apart by a spring 7, are forced against each other and a firing-pin 6 on one of them fires a detonator 5 on the other, the explosion being transmitted from one charge to the other. The charges are held at safe by a forked distance-piece 8 provided with an external plate 9 bound by a band wound round the casing and secured by a hook. The band is unfastened before the grenade is thrown; and when the grenade begins its flight, the band unwinds and the distance-piece falls off, leaving the spring 7 only to hold the charges apart until impact. Two guide-rings 2 are provided on the casing for use when the grenade is discharged from a bombthrower.

Title: Stuffing apparatus for viscous materials
IPC: A22C11/06
Filed: 1962-03-06
Abstract: 992,915. Sausage filling machines. ALLBRIGHT-NELL CO. March 6, 1962 [March 6, 1961], No. 8615/62. Heading A2B. In a sausage filling machine the flow of sausage meat to the stuffing horns 27, 28 is controlled by manually operated valves 166, 167 which exercise automatic control over the rate at which a rotary meat pump feeds sausage meat from an inlet hopper 21 through to conduits 25, 26 supplying the stuffing horns. The valves 166, 167 actuate a pilot control valve 172 forming part of a hydraulic control system regulating the flow of pump-operating fluid along conduit 189 to the pump 29 from a fluid pump 31a worked by an electric motor 31b. With valves 166, 167 closed, i.e. no meat stuffing operation taking place, the valve 172 allows almost complete by-pass of fluid back to the reservoir 36 through lines 192, 193 and 198, Fig. 13. With one of valves 166, 167 open, the by-pass of fluid is effected only through valves 183, 180, sufficient fluid being allowed to reach pump 29 to enable it to pump an adequate supply of meat to the particular stuffing horn in use. When both valves are open the pilot valve 172 allows a flow of fluid through it, via lines 194, 195, 196, 197, only to switch out by-pass valve 183 allowing a sufficiently increased flow of fluid from the pump 31a to reach pump 29 to enable the latter to pump meat to both stuffing horns. The procedure is reversed when the valves 166, 167 are closed. The machine can have more than two stuffing horns, with manual valves to each. The pump 29 operates through a gear box 30 to drive rotary meat impellers in a casing 24 connected to the outlet end piece 23 of the hopper. Both end piece 23 and casing 24 have doors providing access for cleaning and maintenance. The construction of the meat impellers is described, Figs. 8 and 9, not shown.

Title: Improvements in means for retarding high-speed aircraft
IPC: F02K1/62
Filed: 1953-03-30
Abstract: 740,385. Thrust spoilers on jet propelled aircraft. GALLIOT, J. A. N. March 29, 1954 [March 30, 1953], No. 8682/53. Class 4. [Also in Group XXVI] A thrust spoiler for a jet propelled aircraft comprises a deflecting device which is axially movable on the jet pipe and is normally held forward thereon but is displaceable rearwardly when the jet gases are to be deflected, means being provided for obstructing the normal rearward discharge along the pipe when the device is displaced rearwardly, in order to deflect the gases radially outwards into the deflecting device. The jet pipe 26, enclosed within a casing 39, carries an outer, axially movable, sleeve 25 formed on its forward end with a flange 31 acted on by a plurality of compression springs 30 which normally retain the sleeve in the forward position shown on the left-hand side in Fig. 1. The sleeve terminates in a convergent-divergent nozzle 23 formed at its rear end with a head 28 having an annular forwardly facing deflecting surface 27 and carrying a movable diaphragm 35 operated by a wormwheel 41 to close the normally open aperture in the head. The face 27 and the interior face of the nozzle 23 are formed with helical vanes to facilitate the diversion of the jet gases. To effect such diversion, the diaphragm 35 is closed and the resulting gas pressure forces the head 28  and sleeve 25 rearwardly against the action of the springs 30 to the position shown on the right-hand side of Fig. 1, the gases being expelled radially outwards and forwardly by the face 27 to exert a retarding effect on the aircraft. In an alternative embodiment (Fig. 4, not shown), the head 28, instead of abutting the rear edge of the jet pipe as shown to the left of Fig. 1, fits on the outside thereof in the retracted position with the diaphragm fully enclosed within the head. The springs 30 are dispensed with and the sleeve 25 is poweroperated by a rack-and-pinion mechanism. Specifications 389,469 and 606,478, [both in Group XXVI], are referred to.
