Filed: 1924-03-31
Abstract: 451,841. Distant-control systems. SPERRY GYROSCOPE CO., 40, Flatbush Avenue Extension, Brooklyn, New York, U.S.A.-(Assignees of Sperry, L. B.) March 31, 1924, No. 8111. Convention date, March 30, 1923. [Class 40 (i)] A wireless control system for gyro-regulated craft, particu. larly aerial torpedoes, in which the gyro-regulation is effected pneumatically, comprises selectively controlled means operating on the follow-up mechanism of the gyro-regulators for chang. ing the course of the craft. Bombs may also be released by the selective device. The pneu. matic gyro - regulating system is described in Specification 451,843, [Group XXIX] and will be understood from the rudder control shown in Fig. 1. The controlling gyroscope 1 carries an arcuate member 4 which exposes one or other of two nozzles 7 8 when the craft departs from its normal course. The nozzles communicate with opposite ends of cylinder 15 connected to a vacuum tank 11 so that piston 16 moves valve 20 to permit one or other of the bellows 30 31 to collapse and move the rudder 2. The member 33 operated by the bellows is connected to a link 37 which directly rotates the follow-up member 9 carrying the nozzles. The superimposed wireless control operates an air-motor 40 to rotate the follow-up member by means of worm 41. The elevator and aileron controls are similar. The selective control arrangements are shown in Figs. 4 and 5, in which the airmotors 40, 40<1>, 40<11> for the rudder, ailerons and elevator and a bomb-release motor 40<111> are connected to pipes 54 ... 58 connected by a common pipe 53 to the vacuum tank 11. Common pipe 53 is controlled by a normally open master valve 67 and pipes 54 ... 58 are controlled by separate normally closed valves 54<1> ... 58<1> selectively operated by step-by-step ratchet mechanism controlled by wireless impulses. The impulses are repeated by relay 81 to an electrically controlled normally open valve 74. When the valve is closed by an impulse, bellows 71, 72 collapse due to their connection to vacuum tank 11, bellows 71 operating pawl-and-ratchet mechanism 70, 76 and bellows 72 operating a holding pawl 77, but only in response to an impulse of a predetermined length since bellows 72 is slower than 71. The ratchet shaft 69 carries cam 54<11> . . . 58<11> to open selected valves 54<1> . . . 58<1>. The selected motor 40 . . . 40<111> is not, however, operated until master valve 67 is closed by bellows 78 which operates slowly under control of dashpot 67<1>. In a modified form of gyroregulator, the nozzles 7, 8 are replaced by electrically-controlled air valves, the follow-up contact being operated in the manner described above. Specification 227,489, [Class 40 (i)], also is referred to.

Title: Filling nozzle
Filed: 1938-03-18
Abstract: 493,497. Valves ; pipe couplings. MULLER, J. March 18, 1938, No. 8422. Convention date, March 20, 1937. [Class 135] [Also in Group XXVIII] A filling nozzle of the type used for fuelling automobiles and aircraft has a valve controlling the flow through it and a locking device to prevent the valve being opened except when the interior of the nozzle is under pressure. A nozzle of known type, Fig. 1, makes fluid-tight connection with the tubulure 2 of a fuel tank by means of a leather or other joint ring 10 carried by the mouthpiece 11 of the nozzle. A resilient ring A, consisting of a toroidal wire helix 23 having a solid or hollow gapped core 24 which prevents deformation other than expansion and contraction in its own plane, is interposed between the neck 3 of the tubulure and the internal taper 9 of the hood 8 of the nozzle to provide a mechanical connection. Depressing the lever 7 displaces the hood 8 and allows the ring A to expand, enabling the nozzle to be attached to, or withdrawn from, the tubulure. To prevent this being done except when the valve 12 is closed, a locking device is provided comprising a plunger 6, connected to the lever 7, registering with a hole 5 in the valveactuating shaft 13 only when the valve is closed. According to the invention an additional locking means is provided comprising a plunger 18 co-operating with a hole 14 in the shaft 13. A resilient chamber B, having its interior open to the atmosphere, is contracted when the nozzle is under pressure; thus retracting the plunger 18 and allowing the shaft 13 to be turned by the handle 4. The rotary motion of the shaft 13 is converted to an axial movement of the valve 12 by a pivoted lever 16, one end of which engages a cam groove 17 in the shaft whilst the other end presses on the end of the valve stem. Resilient rings similar to the ring A may be used to press the packing 10 against the tubulure 2. In a modification applied to a simpler nozzle having a handactuated valve and an automatic valve, each controlling the flow through it, the plunger, actuated by the resilient chamber, projects into the path of a disc carried by the hand-actuated valve stem unless the chamber is contracted by fluid pressure in the nozzle. The invention may be applied to any pipe line where it is desired to arrest the flow when the pressure falls.
