Title: Improved Process for Making Particles
IPC: B01J2/08
Filed: 1966-09-19
Abstract: 1,161,243. Gelled spherical particles. GULF GENERAL ATOMIC Inc. 19 Sept., 1966 [5 Oct., 1965], No. 41627/66. Heading C1A. Gelled spherical particles are prepared by injecting droplets of a sol into an upwardly flowing stream of an organic liquid which is substantially insoluble in the sol and the velocity of which is sufficient to suspend and carry sol droplets upwards, the organic liquid interacting with the sol during the upward travel to form gelled spherical particles. The sol is preferably a colloidal sol of an oxide in water, e.g. thorium oxide. The organic liquid may be an alcohol, e.g. 2-ethyl-1-hexanol which is preferably heated to maintain the temperature of the upward flowing stream at 50-60 C. Using the illustrated apparatus (not shown) solvent is continuously pumped into the bottom of a column which may be heated, and the sol is injected through the inner of two concentric nozzles, further solvent being injected through the outer nozzle. Solvent flowing from the top of the column is filtered to remove the gelled particles and the solvent is purified, dried and recycled. Oversize particles are removed from the column base. Alternatively a two-column system may be used in which partly reacted droplets from the top of the first column are discharged to the top of a second column and allowed to sink counter to a rising stream of organic liquid. Undersize particles may be removed from the top of the second column.

Title: Apparatus for controlling both the pitch of a variable-pitch ship's propeller and the output of at least one propulsion engine driving the propeller
IPC: B63H3/10
Filed: 1960-12-05
Abstract: 962,173. Variable pitch propellers. ESCHER WYSS A.G. Dec. 5, 1960 [Dec. 4, 1959], No. 41791/60. Heading B7V. [Also in Division F1] A variable pitch ship's propeller 5 is driven by three engines, e.g. diesel engines, steam turbines or gas turbines 1, 2, 3 geared together. Each engine is controlled by a speed governor 6 with a comparatively large percentage regulation, that is, the supply of fuel or steam is varied from zero to the maximum over a large (8-10%) variation in speed, the speed setting of the governors being varied by a lever 11 in the control box 25. Another speed governor 18, with a smaller percentage regulation is fitted to the pitch-changing mechanism 17, and its setting is controlled by a lever 15 in the control box. The pitch of the propeller is indicated on instrument H and the rate of flow of the fuel or steam on instruments F1, F2, F3. In practice, then, the lever 15 controls the speed and lever 11 controls the fuel or steam flow. A member 31 is moved by the lever 15 and two pointers 32, 33 on the member move under scales 27, 28 respectively, the scale 28 indicating the speed selected. A rod 37 slidable in the direction of the axis of rotation of the lever 15 in the member 31 projects at one end into an inclined slot 38 at the other displaced in an axial direction as the member 31 is moved, thus the speed selected is indicated by a pointer 39 at the other end of the rod 37 under an opening 30 in the control box. The handle 11 moves the pointer 36 under the scale 29, showing the engine governor speed selected, and also a cylindrical convex transparent screen 35 can be observed the flow of fuel or steam, the screen being marked with curves of constant flow. The most economical variation of flow with speed is also marked (43). The pointer 39 may be constrained to move only along the line 43 by guiding means, in which case only one of the levers 11, 15 need by operated. The governor 18 may be rendered inoperative by a lever 40. In this condition, the pitch of the propeller may be controlled directly by the lever 15, the pitch being indicated on the scale 27. When the governor 18 is operative, scales 28 and 30 indicating the selected propeller governor speed and the fuel or steam flow respectively, may be illuminated, and when the governor 18 is inoperative scales 27 and 29, indicating the propeller pitch and the selected engine governor speed respectively may be illuminated. The invention is applicable to any number of engines or to plant using engines which are not all of the same type.

Title: Roll-yaw presentation device
IPC: G01C19/32
Filed: 1959-12-14
Abstract: 893,313. Aircraft instrument systems. LEAR Inc. Dec.14, 1959 [Dec.24, 1958], No. 42355/59. Class 40 (1). An aircraft instrument system provides first and second signals each indicating deviation about the roll axis, a third signal indicating deviation about the yaw axis and a fourth signal indicating deviation about the pitch axis ; the indicator can be switched to receive either the first signal or a combination of the second and third signals modified in accordance with the fourth signal. In the Figure a vertical gyro 20 is mounted in gimbals 22 and 23, and has its axis stabilized in the vertical by means not shown, while a directional gyro 21 is mounted in gimbals 25, 26 and 27, and has its axis stabilized in the horizontal by means not shown. The outer gimbals of the gyros are suspended from a common gimbal 29, the long axis of which is fore-and-aft so that rolling of the craft is detected by a pick-off 44 to provide the first signal. A second roll signal is obtained from a pick-off 38 on the vertical gyro and passed to one of the coils of the rotor 33 of a resolver. A yaw signal is applied to the other coil of the resolver rotor from a pick-off 41 on the outer gimbal of the directional gyro. The rotor is turned by a motor 34 in accordance with a pitch signal from a pick-off 35 on the outer gimbal of the vertical gyro. The output of the stator 32 is connected to a switch 46 as an alternative input to the roll signal from the pick-off 44. One of these signals is passed to a motor 51 which rotates a sphere 10 about the axis 16, so that roll information is displayed to the pilot in the form of angular displacement of a mark 18 on the frame 12 of the sphere relative to a fixed mark 19. Normally, the switch 46 passes the roll signal from pick-off 44 to the indicator, and at the same time a ganged switch 47 is open. When the aircraft is climbing or descending, this roll information is inaccurate on account of the roll axis not being parallel to the surface of the earth, and the inaccuracy increases as the flight approaches vertical. To enable the wings to be kept level and the pitch axis parallel with the surface of the earth it is then necessary to modify the roll signal, and switch 46 is put into its alternative position, thus closing switch 47. By the action of the resolver 33 the roll signal from pick-off 38 is progressively replaced by the yaw signal from pick-off 41 as the pitch of the craft increases so that the presented information will be correct. At the same time, the roll signal from pick-off 44 is passed to a torquemotor 30 to lock the common gimbal 29 to the frame of the craft.
