Abstract: 879,982. Fluid-pressure servomotor-control systems. DOWTY FUEL SYSTEMS Ltd. Jan. 30, 1958 [Oct. 30, 1956], No. 33116/56. Class 135. [Also in Group XXVI] A liquid fuel supply system for supplying fuel to a gas-turbine engine includes a fuel pump connected to deliver fuel to the engine, an acceleration control operative on the fuel pump during engine operation to continuously adjust its output controllably to a fuel-flow capable of permitting safe engine acceleration, and an all-speed governor selectively responsive to any speed within a range of engine speeds to control a by-pass valve to by-pass fuel controllably from the fuel flow adjusted under control of the acceleration control in order to tend to maintain any selected engine speed. The variable displacement pump 1 delivers fuel past a metering valve into a delivery line connected to a by-pass valve 52, the metering valve being controllably positioned by differential pressure on servo piston 18, under the control of a vent valve 14, hinged at 13, which is spring connected to the metering valve and responsive to compressor delivery pressure acting in bellows 7. A servomotor controlling the pump displacement comprises a servo piston 46 acting on the displacement changing lever 44 of the pump, pressure beneath this piston being controlled by a vent valve 25, hinged at 24, which is responsive to the pressure drop across the metering valve 5 applied to diaphragms 21, 22, and is also responsive, through spring-loaded cup 33, lever 32, track 37 of this lever, guided cam follower 31 and cam 30, to engine speed and compressor ram entry temperature, which two variables are transformed by a function generator 28 into cam movement through cam-shaft 29. Another servomotor, controlling independently the by-pass valve 52, comprises a servo piston 53 of this valve, and means for varying the pressure beneath this piston comprising an allspeed governing device 57 having a vent control valve 56, hinged at 62, and responsive to compressor delivery pressure in bellows 64a and to a pressure signal derived from engine speed which is applied to diaphragms 60, 61. A pilot's control lever 66 acts through spring 63 on the hinged vent valve 56. The pressure signal on diaphragm 61, which is supplied through restrictor 69, is modified by a maximum engine speed governor 71 acting on a further vent control valve 70. The leverage exerted by bellows 7, bellows 64a, and cam 30 on their respective vent valves is adjustable by screw devices 12, 66a, and 38, respectively. In order to prevent an insufficient fuel flow to maintain combustion when reducing speed by altering the setting of the all-speed governor, a throttle valve 73 is provided in series with the by-pass flow into valve 52. Specification 834,916 is referred to.

Title: Automatic hovering gear for submarines
Inventor: WORTHING NICHOLAS
IPC: B63G8/22
Filed: 1962-08-29
Abstract: 980,651. Valves. HARLAND ENGINEERING CO. Ltd. Aug. 29, 1962, No. 33178/62. Heading F2V. [Also in Divisions B7 and G3] The buoyancy of a submarine is controlled by filling and emptying a tank 4, Fig. 1, which is connected to an external tank 2 with a vent 3 by a pipe 16 containing a pump 12, a pressureactuated valve 17, a distributing valve 7, a pipe 8, and a hover valve 9; the valve 17 controls flow in a pipe 18 opening into the tank 4. The apparatus functions when depth can no longer be maintained by the normal hydroplanes. The valve 7, Fig. 2, is a double-landed piston 32 with a through bore 42 which is connected via a duct 44 to the pipe 18, the piston controlling ports 37, 38 and 39. The valve 17 consists of two pistons 55, 65 the latter having double the effective area of the former, each piston having a stop 56, 66 whilst a spring 67 is disposed between the pistons. The space 41 between the pistons leads to the lower set of distributing ports 39; the upper piston 55 controls ports 63 leading to the pipe 18. The piston 55 is open to the pressure in the line 16 and the space below piston 65 is connected to the pipe 8 through a restriction. Upon lifting the piston closure 32, the pump output is directed through ports 37 and 38 to the pipe 8. When the closure 32 is lowered the ports 37 closed and water flows from the tank 2 via ports 38, 39 to space 41, the pressure in pipe 16 lowering piston 55 and enabling the pump output to flow through ports 53 into space 41. The pressure in the latter lowers the piston 65 to open ports 63 whereby all the fluid in space 41 is discharged into pipe 18. The valve is controlled by means responsive to the depth error of the submarine and vertical velocity and acceleration, the error detecting means consisting of a ball valve 88 opened by an adjustable spring 96, loading of which is set for a desired depth, and opposed by a bellows 97 detecting actual depth by hydrostatic pressure. The ball valve 88 controls the flow into lines 101, 102, 103 a depth gauge 105 being connected to line 101; each line opens through a throttle 127 into a chamber 126 of a separate one of three servo-devices A, B, C, arranged in cascade, the last device C actuating the valve 7. The servo-devices are identical, each comprising a pilot valve 125 operated by the pressure in chamber 126 and controlling movement of a piston 114 in a cylinder connected by a duct 136 to the chamber 126 of the next device, from which chamber the fluid escapes via the associated throttle; the fluid connections of the last device C are slightly different as shown. A lever 113 and spring 111 provide a " feedback " between each piston 114 and pilot valve 125. An accumulator 160 is connected to each chamber 126 to smooth out the effect of wave motion. The pilot valves and " feedback " mechanisms are rotated to minimize friction through gearing driven by the electric motor 86 driving the supply pump 82. The fluid in the system is heated by thermostatically controlled heaters 170, 171.

Title: Manufacture of yellow azo-dyestuffs
Filed: 1928-11-13
Abstract: 325,229. Imray, O. Y., (I. G. Farbenindustrie Akt.-Ges.). Nov. 13, 1928. No Patent granted (Sealing fee not paid). Samples furnished. Azo dyes are prepared by coupling the diazo compound of a base of the general formula wherein the two phenyl residues may be substituted or not, with a pyrazolone of the general formula: wherein X = CH3, COOH or COO-alkyl and the nucleus Y may be unsubstituted or may contain an alkyl or sulphonic group or simultaneously an alkyl and a sulphonic group. Non-sulphonated dyestuffs mav be subsequently sulphonated. They mav be used for wool or silk or as lakes. If the dyestuffs contain in the pyrazolone component a carboxyl but no sulphonic group, they are also suitable for dyeing acetate silk. In an example diazotized m-aminobenzene sulphonic acid methyl (or ethyl) phenylamide is coupled with 1-(4'- sulphophenyl)-3-methyl-5-pyrazolone. Other diazo components specified are 1 - methyl - 4 - aminobenzene-2-sulphonic acid methylphenyl- or otolylamide. Sulphonamides of the above type are made by first condensing a m-nitrophenylsulphochloride with a phenylamine, replacing the hydrogen atom of the sulphophenylamide group by an alkyl group and then reducing the nitro group. Alternatively, a m-nitrophenylsulphochloride may be condensed with a phenylalkylamine and reduced. Reference has been directed by the Comptroller to Specification 312,582.

Title: Facsimile telegraph systems
IPC: H04L9/38
Filed: 1947-12-17
Abstract: 655,320. Copying-telegraphy. STANDARD TELEPHONES & CABLES, Ltd. (Materiel Telephonique Soc Anon). Dec. 17, 1947, No. 33286. [Class 40 (iii)] Relates to a facsimile telegraph system in which the scanning operation is effected according to a code so that the message may only be deciphered by a receiver executing a scan according to the same code. The message is scanned line by line, successive lines being scanned in opposite directions in different transit times. Successive lines scanned are also made non-adjacent. In Fig. 5, 2 represents the message and 1 the axis of the transmitter scanning or receiver printing device. This is mounted on a carrier 3 and reciprocated by cam 6 to produce line scans in alternate directions. In order that each scan may take place at a different speed the drive to cam 6 from motor 10 is obtained through differential 13, 15, 17, the cage 18 of which is rotated one way or the other by a second cam 19. With this arrangement the angular speed of pinion 15 and cam 6 differs from that of the drive pinion 13 by the speed of the cage rotation. A sequence of operation for 6 scans is described, during which cam 19 completes one revolution. Cam 19 may be keyed to its shaft in any position and cut according to any law to provide complicated speed variations. A regular line by line upward movement is imparted to carrier 2 by worm 24 driven through gears 26, 27, and in order to produce non-adjacent line scanning additional movements, both upwards and downwards, are added by a cam 30. Worm 24 slides in bearings 28, 29 and at the lower end has a cam follower 31. Cam 30 and an escapement wheel 33 are carried by a sleeve which is loose on shaft 37 but is arranged to be rotated by the shaft through spring 34. Shaft 37 is driven from the cam-shaft 16 through gears 38, 39 and the arrangement is such that, at the end of each line scan, a lobe on disc 41 knocks out pawl 40 allowing the escapement wheel and cam to turn rapidly until stop 35 comes against dog 36. In the typical code of operations described cam 30 is shaped to impart, in sequence, the movements : 6 lines upwards, 3 lines upwards, 9 lines downwards. These movements, added to the regular upward movements of one line, result in a scanning line sequence as follows : 1, 8, 12, 4, 11, 15, 7, &c.
