Title: Planetary cooler
IPC: F28C3/10
Filed: 1973-05-09
Abstract: 1411905 Planetary coolers for rotary kilns F L SMIDTH & CO AS 25 April 1974 [9 May 1973] 22097/73 Heading F4B In a rotary cement kiln with planetary cooling tubes one or more spray nozzles are arranged to introduce cooling water into the outlet ends of the tubes. As shown three water spray pipes 19 have valves 21 opened when a pipe is in alignment with a cooling tube 12 by cam followers 24 engaging recesses in cam rings encircling the kiln. The water supply is controlled by a main valve (25, Fig. 4) subject to the action of a thermocouple 26 in the clinker discharge hood 16, which may also control the amount of water supplied by electromagnetically operated valves (29, 30, 31 Fig. 5). In another system (Fig. 6) the cam control is dispensed with, the valves 21 being controlled electromagnetically from a photoelectric cell 33 in the hood 16. A modification (Figs. 7 and 8) has an open reservoir (35), water from which picked up by a scoop (39) rotating with the cooler is circulated through a ring pipe to individual pipes (44) in each cooling tube. Another modification (Figs. 9-13) has a water trough (45) surrounding and spaced from the cooler supplied with water from a pipe (47) with a flexible joint (48) to a supply line (49). A pipe (50) from the trough to each cooling tube terminates in a conical disdistribution baffle (51). A further modification (Figs. 14 and 15) has nozzles (56) movable through a slit 57 in the casing wall as the cooling tubes pass by. Permanent magnets (66) on the kiln wall activate indicators (67) and (70) associated with the cooler to open and close valves supplying the cooling water. Final modifications (Figs. 16 and 17) apply a similar system to devices supplying two and three cooling tubes with water at once.

Title: Improvements in or relating to a reversible motor
IPC: F01C1/344
Filed: 1955-08-02
Abstract: 776,325. Rotary motor. ARO EQUIPMENT CORPORATION. Aug. 2,1955 [Nov. 9, 1954], No. 22204/55. Class 110 (2). A reversible fluid motor 10 of the sliding vane type for use in a hoisting device has, for the forward direction of rotation, an inlet port 52, a primary exhaust port 60 and a secondary exhaust port 54, the port 60 being offset from the midway position C by an angle of 28 degrees towards the port 54. Compressed air supplied to the port 52 is controlled by valve means operated manually by flexible elements 36, 38 which can also reverse the supply of compressed air making port 54 the inlet and port 52 the secondary exhaust for reverse running. The offsetting of the primary exhaust port 60 causes a differential in power between the forward and reverse directions substantially equal to 2 to 1. Recesses 62, 64 prevent compression of the air as it is being exhausted.

Title: Fuel tank inerting apparatus
IPC: B64D37/32
Filed: 1973-05-10
Abstract: 1416352 Fire protection PARKER-HANNIFIN CORP 10 May 1973 [9 June 1972] 22343/73 Heading A5A Apparatus for protecting a fuel tank (10), e.g. in an aircraft, from fire comprises means (18) for introducing liquid fuel into the tank, means (11) for mixing ullage gases with incoming fuel, means (33) for separating gases from the incoming fuel, and means (38) for venting the separated gases from the tank. The separator (33) is a container open at its top, e.g. by a duct (36), to the vent and open at its bottom (34) to the tank. As shown, 18 is a filling valve and 11 an ejector aspirator. Conduit 31 enters the separator 33 tangentially to impart swirl to the fuel. Vent manifold 39 communicates with the ullage space at 40 and 41 as well as with the conduit 36, and is closed by relief valve 43. A Dewar vessel 45 contains liquid nitrogen, which can be released into the tank through a nozzle 47 in response to a control 51 that senses pressure differences between the inside of the tank and outside. An emergency dive valve 55 opens in response to a larger pressure differential than that to which the device 51 is sensitive. The effect of the device is that when fuel is pumped into the tank, the gases dissolved in it are equilibrated with those in the ullage; when pressure is reduced, e.g. the aircraft climbs, gases are vented to atmosphere; when pressure rises, e.g. the aircraft descends, nitrogen is released into the ullage by device 51, but if this fails, then air is admitted instead by valve 55. In other embodiments for use when the separator (33) is near the bottom of a deep tank: (Fig. 3 not shown) the lower end of the duct (36) is closed by a valve (60) operated by a float (61) inside the separator; (Fig. 4 not shown) the lower end of duct (36) is almost closed by a disk with a small orifice, to keep the fuel surface inside the separator low enough to avoid flooding; (Figs. 5 and 6 not shown) the lower end of the duct (36) extends below the opening (32) and has a closed lower end with circumferentially arranged slots near the closed end, so that as the liquid level rises, it partially closes the slots.

Abstract: 188,812. Mann, E. L. Aug. 24, 1921. Machinery, utilizing inertia to obtain movements in. - In apparatus for utilizing the rolling, rocking, vibrating, or jolting movements of ships, rail and road vehicles, &c. for the production of power or motion or for indicating such movements in a normally stationary body, a heavy plate 1, Figs. 1 and 2, moves substantially horizontally on loose balls 5 in a frame 2, stops 6 preventing jumping, and means being provided for limiting rotation if the plate is circular. Buffers 3 prevent shock. Pawls 8 are pivoted on the plate 1 and pressed by springs x into engagement with a ratchet-wheel 9 secured on a vertical spindle 10 carried in standards 5, so that the spindle rotates always in one direction as the plate 1 moves. Cords 13 may be attached to a pin 14 on a disc 12 on the upper end of the spindle 10 to convey motion to apparatus to be actuated. In the form shown in Fig. 3, a rocking lever 15 is supported by a ball socket 16 and carries a ball end 17, engagring the ptate 1, and a plate 19 to which are attached cords 20, preferably four in number, passing over pulleys 23 on extensions of the standards 7 to the part or parts to be operated. In a modification, the cords may be attached directly to the plate 1, or this arrangement may be combined with either of those shown in Figs. 1, 2, and 3. The motion of the lever 15 may be converted into rotary motion.

Title: Modulating inline valve
IPC: F16K31/42
Filed: 1966-05-20
Abstract: 1,078,047. Fluid-pressure servomotor systems. VAPOR CORPORATION. May 20, 1966 [Sept. 17, 1965], No. 22559/66. Heading G3P. [Also in Division F2] A servo-operated valve comprises a main closure member 16 integral with a piston 15 working with clearance in a cylinder 13 suspended by rib 14 in a casing 10. A spring 47 urges the main valve towards seat 17 surrounding the outlet 12. When a solenoid valve 18 is operated to vent cylinder 13, the fluid-pressure acts on the piston to open the main valve and the latter moves until a rod 51 opens a pilot valve 48, 49 to admit fluid to the cylinder. The pilot valve comprises a rotatable and axially movable member 49 urged by spring 50 into contact with the rod 51. Partially surrounding member 49 is a sleeve 48 defining a helical track (53) the ends of which merge with tracks (54, 55), the latter being perpendicular to the axis of the sleeve. The pilot valve opens when the end of an axial groove (58) in member 49 moves past the part of the helical track aligned therewith. A member 20 responsive to the pressure or temperature of the fluid rotates member 49 relative to sleeve 48 to determine what travel of the main valve is necessary to open the pilot valve.

Patent GB-605447-A (GB)
Title: Improvement in polymeric materials
IPC: C08K5/17
Filed: 1944-11-17
Abstract: Polyvinyl fluoride is produced by polymerising vinyl fluoride containing between 10 and 1500 parts of each of oxygen and acetylene per million parts by weight, at an elevated temperature and superatmospheric pressure.  The moulding characteristics, fusibility and solution viscosities of the polymers vary with the ratio of acetylene to oxygen content, which is preferably between 1 : 1 and 3 : 1.  The vinyl fluoride containing 10 to 1500 parts per million of oxygen and acetylene can be obtained by removing the acetylene completely followed by introduction of the required amount of acetylene, or the acetylene is partially removed by scrubbing the gas with e.g. ammoniacal cuprous chloride until the acetylene remaining is of the required amount.  Oxygen may, likewise, be added or introduced during the washing or drying of the vinyl fluoride.  In the example, polymerisation is effected in the presence of benzoyl peroxide, as catalyst, and water, at a temperature of 100 DEG  C. and pressures of 425-950 atmospheres.  The polymers are useful in the manufacture of films, threads, fibres and moulded objects. Specification 605,445 is referred to.
