Title: A method and apparatus for compacting finely divided solids
IPC: C08K9/00
Filed: 1955-12-28
Abstract: 789,841. Forming pellets from finely divided solid material. DOW CORNING CORPORATION. Dec. 28, 1955 [Jan. 10, 1955], No. 37148/55. Class 87(2). [Also in Group XXX] A method of pelletising a finely divided solid, e.g. synthetic silica or carbon black comprises compressing the solid so that substantially all the air between the particles is expelled, subsequently compressing the solid to a bulk density of at least 4 pounds per cubic foot and thereafter tumbling the compressed solid for a time sufficient to form pellets which are substantially dust free. The material 10 to be pelleted or granulated is fed from a hopper 11 on to a lower conveyer 13. The front wall of the hopper is cut away at 14 and material passes through the opening and comes into contact with an upper conveyer 12. The conveyers move together over a support platform 42 and edge rollers 21 and runners 18 are arranged so that the edges of the upper conveyer are held against the lower conveyer, Fig. 4b, to prevent the escape of the material. The upper conveyer 12 is made of air-permeable material, e.g., canvas, and as it passes under rollers 22, 23 air is expelled from between the particles and escapes through the conveyer. The rollers 22, 23 also prevent billowing of the conveyer as it approaches squeeze rollers 43, 44, which also drive the conveyers. The de-aerating pressure may be applied by bars attached to the runners 18 at positions progressively nearer the support platform 42, or by a perforated plate 46, Fig. 4b, above the upper conveyer appropriately sloped, being rigidly or pivotally mounted and adjustable in the latter case. The edges of the upper conveyer 12 may be headed at 47 so as to be guided by the runners 18. The squeeze rollers 43, 44 should be of different diameters, e.g., the diameter of the lower roller 43 twice that of the upper roller 44, and their distance apart is adjustable, by means of a nut 40, for the material to be compressed to the required bulk density. Preferably at least one of the rollers is rubber coated. The compressed particles are removed from the conveyers by scrapers 24, 25 and fall through a shoot 26 into a tumbler 27. A roller 30 gives a better scraping angle to the upper conveyer and a roller 31 prevents it from flapping. The bearings for the idling roller 39 at the other end of the conveyer 12 are carried in posts 37 which are slidable and can be adjusted in position by screws 34, and the bearings for the idling roller of the lower conveyer are slidable in the frame and adjustable by screws 33 ; thus the tension of the conveyers is adjustable. Modifications are mentioned whereby the material is de-aerated by reciprocating one conveyer relatively to the other, and whereby the conveyers may be vertical.

Title: Gas Steering and Propulsion System for Underwater Missiles
IPC: F42B19/01
Filed: 1960-10-28
Abstract: 1,169,161. Underwater missile. CLEVITE CORP. 28 Oct., 1960 [2 Nov., 1959], No. 37220/60. Heading B7A. [Also in Division G3] An underwater missile comprises a fluid storage vessel coupled to a first fluid operable control surface for steering the missile in elevation, to a second fluid operable control surface for steering the missile in azimuth, and to a gyroscope; an ambient pressure and elevation responsive control valve to control fluid supply to the first control surface; and a control valve actuated by the gyroscope to control the fluid supply to the second control surface; and means for preventing reflection of pressure changes between the fluid supply means to the two control surfaces. In Fig. 1 liquid carbon diode is stored in a tank 15 and can be released from it on the firing of squib 18 by a manually timed or pressure operated switch 23. Gas then passes through line 26 to start a gyroscope 28; once the gyroscope is started a sequence valve 25 shuts off the gas supply to the gyro and supplies gas through a pressure regulating means 21 to a piston mechanism 30 which uncages the gyro. The main gas supply passes through an evaporator coil 35 to drive the engine 11 turning the propellers 12 and through conduit 41 to the steering means. The vaporizer means preferably comprises a double-walled section of the hull with the outer skin in heat transfer relationship to the surrounding water. From conduit 41 gas passes through a pressure reducing valve 42 to line 46 which branches into lines 47 and 48 feeding the azimuth and elevation steering controls respectively, the pressure in lines 46 being high enough to prevent interference between depth and azimuth steering. Line 47 feeds a pair of orifices 51, 52 the outputs of which are connected to two rudder actuating pistons 53, 54 which are also connected to bleed valves 56, 57 in a gyrocontrolled valve 50. The valve body 58 is controlled by the gyro 28 to vary the effective areas of the ports 56 and 57, if the missile deviates from course, and thus cause appropriate correcting rudder movement. Gas which exhausts from valves 56 and 57 passes through valve body 58 into turbine buckets of gyro 28 to keep the gyro rotating. For control of elevation, the pistons 63, 64 operating the elevator 65 are connected to ports 77, 79 of elevation control valve 67. The valve body is controlled by a pendulum, comprising two hanging rods 91 carrying a weight 92, and a sleeve inside the valve body is operable by a pair of bellows 83 and 85; the valve body and the sleeve control the effective areas of ports 77 and 79 and so control the depth. One of the bellows 85 constitutes a reference pressure and the other 83 is connected to ambient water pressure; a limit stop may be provided for the lever actuated by the bellows to prevent excessive dive angles.
