Title: A fuel flow controlling device for a gas turbine engine
Inventor: BOTTOMS HARRY SIMISTER
IPC: F02C9/16
Filed: 1962-05-09
Abstract: 975,807. Valves. JOSEPH LUCAS (INDUSTRIES) Ltd. May 20, 1963 [May 9, 1962], No. 17805/62. Heading F2V. [Also in Division F1] The invention relates to a device having a variable metering orifice for controlling the flow of fuel to a gas turbine engine, the device comprising a body 1 in which is formed a cylindrical bore, a hollow cylindrical member 2 being mounted for axial movement in the bore, the cylindrical member having formed in its wall an aperture 6, the arrangement being such that the axial position of the cylindrical member determines in part at least the effective open area of the aperture. In accordance with the invention, an arm is secured to the cylinder and extends radially therefrom, the outer end of the arm being connected by a link with a part which is adapted to be oscillated relative to the axis of the cylinder when the engine is operating, the link permitting free movement of the cylinder with respect to the part in a direction parallel to the axis of the cylinder. In the embodiment shown in Fig. 1, the hollow cylindrical member 2 is mounted for axial movement in a bore in the housing 1, the cylindrical member being formed with apertures 6 and 8, and its axial position being controlled by a capsule 15 in response to air pressure. A cylindrical sleeve 3 is mounted on the cylindrical member, the end of the sleeve co-operating with the apertures 6 to control the effective open area thereof. The axial position of the sleeve is controlled by centrifugal weights 4 which act against the loading of a spring 5. Fuel supplied to the inlet 7 flows through the metering orifices 6 into the space within the cylindrical member 2, then passes through apertures 8 and through outlet 9. The cylindrical member is provided with a radially-extending arm 13, the outer end of the arm being connected by means of a link 14 to a weight 10 which is disposed between a pair of springs 12, the springs acting at their other ends against brackets 11 secured to the housing 1. In operation of the engine oscillatory movement of the weight is transmitted by means of the link 14 and arm 13 to the cylindrical member 2 thus eliminating the effect of static friction. In Fig. 2 the arm 13 is connected by a link 16 to a second arm 17 which is mounted for angular movement in a bearing 18, the arm 17 being connected by a link 19 to the engine casing whereby oscillatory movement is transmitted to the cylindrical member 2. The link 16 is slidably connected to the arm 17 so as to permit axial movement of the cylindrical member. In a similar embodiment the link 19 is oscillated by means of an eccentric on an engine-driven shaft. In a further embodiment the link is oscillated by means of an electrical vibrator.

Title: Improvements in the oxidation of polysulphides
IPC: C08G75/20
Filed: 1949-07-07
Abstract: Polysulphones having fibre-forming properties are obtained by oxidation of polysulphides having the general formula -R-S-R1-S-R-S-R1-where R and R1 are the same or different divalent organic radicles and preferably contain a chain of at least 3 carbon atoms, the oxidation being performed by means of a peroxide, e.g. hydrogen peroxide, in a medium comprising formic acid of concentration sufficient to precipitate the polysulphone as it is formed, e.g. a concentration of 70-90 per cent.  Temperatures of 50-100 DEG  C. are specified and other peroxide compounds, e.g. addition products, i.e. 2Na2CO2.3H2O2 and hydroperoxides may be employed.  Poly-sulphides specified are poly-tetra-, -penta-, -hexa-, -octa-, -deca-, -dodeca-sulphides, poly-p-xylylene sulphide, and poly-dibutylene ether sulphide.  The intrinsic viscosity of the polysulphone is of the same order of the polysulphide used which should have a viscosity of 0.4 or higher in order to obtain fibre forming polysulphones.  In examples (1) 1 part polyhexamethylene sulphide viscosity 0.64, dispersed in 40 parts 90 per cent formic acid was heated to 50 DEG  C. and 1 part 30 per cent hydrogen peroxide added gradually to maintain the temperature constant.  An additional 1 part peroxide was added, whereupon the polysulphone began to precipitate as a fine powder. The precipitation was continued while adding a further 2 parts of peroxide.  The polysulphone obtained had a m.p. of 212 DEG  C. and viscosity 0.71 poises and was melt spun into filaments at 230 DEG  C.; (5) poly-dibutylene ether sulphide; (6) poly-dibutylene tetramethylene sulphide were similarly converted to polysulphones.

Title: Improvements in apparatus for the treatment of water
IPC: C02F1/42
Filed: 1928-06-22
Abstract: 293,033. Aktiebolaget Filtrum. July 1, 1927, [Convention date]. Purifying liquids.-In apparatus for removing calcium, iron, and manganese compounds from water by means of treating-material requiring periodic regeneration, the valves controlling the flow of regenerating and washing liquids are operated by a servomotor which is released to operate the valves by the flow of the water under treatment. In the form of apparatus shown, the servomotor comprises a hydraulically-operated piston 3 working in a cylinder 5, the valves controlling the regeneration operation are formed in a single plug cock 2, which has four operative positions, and the servomotor is released for operation by a meter B, placed in the inlet or discharge pipe 1 of the apparatus. With the parts in the position shown, a spiral cam 14 on the meter B has just allowed a hammer 11 to fall and turn a lever 15, thus allowing the upper end 17 of the lever to release a lever 20, turning on the spindle of the valve 2. This lever carries a weight 19; and engages a roll 25 at the top of the piston rod 24, so that, in falling, it pushes the piston to the lowest point of its travel, and causes it to turn by means of an arm 26 a spring-controlled valve 28, thus admitting water under pressure from a main 30 to a pipe 10 and the space below the piston. The piston, in rising, lifts the lever 20 and causes a pawl 31 thereon to engage with a recess a in a control disc 23 fixed to the spindle of the valve 2. The latter is thus rotated as the lever rises to the position II, this quarter turn corresponding to the first operation of the regeneration valves. At the end of its upward travel the piston rod causes the valve 28 to close the connection of the pipe 10 with the pipe 30 and open it to a pipe 29 leading to a channel 6 in the valve 2, through which the water from below the piston is discharged. On the fall of the piston the valve 28 is again reversed, and the motion is repeated, the pawl 31 engaging successively in recesses a - - d in the disc 23, so that the plug cock takes successively each of its four positions. The passages 6 - - 9, which in the several positions communicate with the pipe 29, have different cross-sections so that the water from below the piston is discharged more slowly or rapidly to determine the period during which the plug cock remains in the corresponding position. Just before the cycle of operations is completed a projection on the lever 15 engages a recess 21 on a control disc 22 and the end 17 engages the lever 20 so that it is held until the meter again allows the hammer 11 to fall.
