Title: Control systems for variable speed gas turbine power units
Inventor: SKELLERN JOHN
IPC: F02C9/28
Filed: 1956-05-14
Abstract: 811,563. Gas turbine plant. NAPIER & SON Ltd., D. May 3, 1957 [May 14, 1956], No. 15013/56. Class 110 (3). [Also in Group XXIX] A control system for a variable-speed gas turbine power plant has a device for sensing the turbine inlet temperature and operable to adjust the fuel supply in response to any difference between the sensed temperature and a datum temperature to which the device is set, the datum setting means being actuated by the speed selecting device, and a delay device being interposed between the latter and the datum setting means whereby the delay in adjustment of the datum in response to a change in selected speed is comparable with the thermal inertia of the temperature sensing device. Alternatively the delay may be greater to provide an acceleration control. As shown, turbine inlet temperature is sensed by a mercury-filled bulb 27 connected to a Bourdon tube 29 which, through a lever 31 with an adjustable pivot 32, operates a valve 33 controlling a bleed 54 from the fuel supply conduit on the downstream side of a metering unit (not shown) which meters the fuel in accordance with the selected speed setting and embodies means for compensating for variations of temperature and pressure of air entering the compressor of the plant. The position of the pivot 32 is moved to adjust the datum temperature by a servo-piston 39 acting through a lever 48 with an adjustable fulcrum and under the control of a valve 38 which is movable relative to a restricted orifice 46 in the piston by a lever 37 which has a connection through a cam 35 and shaft 34 with the speed selector 25. Pressure fluid is continuously supplied to the lower side of the piston 39 through a pipe 42 and to the upper side of the piston through a restriction 44, the valve 38 controlling an outlet from the space above the piston so that the latter follows-up the movement of the valve. The delay in the setting of the datum is caused by the restrictions 44, 46. Anti-clockwise movement of the cam 35 at a greater rate than is allowed by the rate of movement of the piston 39 is provided for by a spring-loaded follower 47. The system may be employed in a helicopter with twin rotors driven by separate power plants wherein failure of one plant would necessitate the running of the other at emergency high power output. In this case each power plant has a torque meter on its output shaft with a pressure connection 55 to a piston 56 in the control system of the other plant whereby the temperature sensing mechanism of one plant is rendered inoperative by loss of torque in the other plant. Specification 811,564 is referred to,

Filed: 1944-08-08
Abstract: 581,095. Stretching. LOEWY ENGINEERING CO., Ltd., and SALTER, F. S. Aug. 8, 1944, No. 15020. [Class 83 (iv)] In a machine for stretching metal bars, sheets, &c. in'order to straighten them, means are provided for indicating the initial length of the bar &c. and for indicating the total elongation during stretching so that a total stretch may be performed to produce a given percentage elongation. The bar M is gripped by an adjustable fixed head 12 and a movable head 11, the head 12 being mounted on a carriage 16 adjustable along the machine bed by a motor 19, worm gearing 20 and chain and sprockets 23, 24, and being locked in working position by hooks 17 engaging notches 18 on the bed. The head 11 is moved during stretching by a hydraulic ram 14 supplied from a pump 69 under control of a manuallyoperated valve 70 and the operating pressure is indicated by a gauge 63 and adjusted by a relief valve 67 which is set to the required pressure by a knob 66 and graduated dial 65. Adjustment of the head 12 is indicated directly on a linear scale 26 and a sprocket 27 on the adjusting shaft 21 is connected to a shaft 30 carrying an indicating dial 31. An outer scale A, Fig. 4, on dial 31 is graduated in total lengths of the bar M from 100 to 600 inches and a series of inner scales B give the inches of stretching required to produce an elongation of from 1 per cent to 5 per cent. The figures on scales B correspond to a figure on scale A which is diametrically opposite on the dial. The head 11 carries an arm 41 connected by a chain 42 to a sleeve 44 rotatable on shaft 30 and formed integral with part 45 of a friction clutch, the other part 46 being attached to an indicating dial 48 graduated in inches of stretch of the bar M. A dog 59 on the dial 48 engages a graduated Geneva wheel 60 once per revolution to indicate multiples of ten inches of stretch. A mask 84, Fig. 3, overlying the scales B has a series of windows 75 and is rotatable by a knob 86 so as to bring one of the windows over the scale B which indicates the required percentage elongation. In operation, to produce a 4 per cent elongation in a bar 280 inches long, movement of head 12 to the position which accommodates this bar will bring the 280 graduation of scale 31 opposite a fixed window 83, as shown in Fig. 3. Adjustment of mask 84 to bring the 4 per cent window 75 within a fixed window 82 will show 11.2 inches. as the required total stretch, and the valve 70 may then be actuated to move the head 11. When the pressure in the supply line 62 has reached the value necessary to start stretching of rod M, fluid in a branch 621 will actuate a piston 53 to rock a lever 50 and engage clutch 45, 46, whereupon dials 48, 60 will be rotated to indicate the inches of stretch imparted by head 11 to the bar M. When this value, seen in a fixed window 81, Fig. 3, reaches the value shown in window 82, the stretching operation is stopped. On release of pressure in the line 62, the clutch 45, 46 is disengaged by a helical spring and the dial 48 is returned to zero position by a volute spring.

Abstract: 692,574. Filters. BRUCKENBAU FLENDER GES. June 16, 1950 [Aug. 5, 1949], No. 15123/50. Class 46 [Also in Group XXX] An apparatus for dewatering solid-liquid mixtures such as a slurry of fine coal, consisting of a static dewatering tower having preferably parallel sides and an inlet for the material to be dewatered adjacent to its upper end and a water outlet adjacent the lower end is characterized in that the tower is erected in an inclined position and is provided with a screen arranged over its lower inclined bottom wall and preferably extending over the entire surface. Slurry is supplied to a tower 1 from an inlet 2 and comes to rest against a wall 3 and hinged plate 3<SP>1</SP>. Water drains away through screens 6 to an outlet 8 connected to a collecting receptacle 18 communicating with a discharge tank 21 by a pipe 20. Dewatering may be assisted by suction provided by a vacuum pump 19, the pipe 20 in this case acting as an atmospheric seal. Compressed air may be introduced for agitating the tower contents or for cleaning the screens, a cock 22 being closed at this stage. In Fig. 2 the tower 1 is subdivided into zones 13 ... 16 by the provision of spaced draining pippes 9 ... 12, the zones being operable independently. The screen 6 may be arranged in step-like form, Fig. 3 (not shown). As in Fig. 1 an upper screen 7 may be provided and the tower may be closed or provided with a cover as shown. With independent operation of the zones the uppermost of them effects a preliminary dewatering of the mixture as it slides down the inclined bottom 5. For this purpose the suction pipe 24 of the uppermost zone is closed and the valve 26 in the by-pass pipe 25 opened, after which thewater may drain freely from the tank 21. Further dewatering by suction takes place in the various zones in succession as soon. as the material has sealed the screen of the particular zone from the outside air. When the tower is full the uppermost zone is again connected to the vacuum pump, whereupon final dewatering of the remaining zones is effected simultaneously.
