Title: Apparatus for preventing explosions of volatile liquids
IPC: B64D37/32
Filed: 1941-12-04
Abstract: 554,534. Explosions, preventing. RAYNER, G. F., (Atep Corporation.). Dec. 4, 1941, No. 15636. [Class 47 (ii)] [Also in Group XII] An apparatus for preventing explosions in partly filled containers holding volatile organic liquids comprises a container 10 partly filled with the liquid to a level determined by a valve operated by a float 39, a pipe 16 opening to the atmosphere and leading by a non-return valve 27 to the underside of a submerged disc 31 formed with a series of circular grooves 32, a pipe 18 leading to the space above the liquid in the main container and communicating by a non-return valve 20 with the under-side of the plate via the valve 27, a venturi 35 through which air is sucked when the pressure in the main container is less than that of the atmosphere, the flow causing a flow of the liquid by a pipe 33, the mixture, too saturated to explode, passing to the pipe 18 by a pipe 24. The apparatus is specially intended for diving aeroplanes, when the lower end of the pipe 33 should be near the forward edge of the disc 31. During diving, a saturated mixture flows into the vapour space of the main tank by the venturi and pipe 18. Flow in the opposite direction passes by the valve 20 to the atmosphere. Normal lowering of liquid level in the main tank causes a flow of air by the pipe 16 and valve 27, whence it bubbles through the liquid in the container 10 and passes by the venturi to the vapour space of the tank.

Title: Improvements in and relating to propelling mechanisms
IPC: F03G5/00
Filed: 1943-09-24
Abstract: 575,683. Propelling mechanisms. VANNECK, V. P. BOURNE-. Sept. 24, 1943, No. 15687. [Class 114] Mechanism for propelling a ship, train, motor car, aeroplane, torpedo or the like comprises a prime mover or other source of power which exerts force between one or more fixed abutments and one or more solid, liquid, or gaseous mobile bodies so as to produce concurrent movement of each abutment and mobile body in opposite directions, and means for bringing the mobile body to rest in relation to the ship or the like by converting its momentum into electrical, heat or other form of energy which may be used in the prime mover or in some auxiliary mechanism. The source of power may be an explosive, an internalcombustion or steam engine, a turbine, or an electric motor, and it may actuate a cam, eccentric, or piston to produce a rapid succession of impulses between the abutments and the mobile bodies. Steering and speed control may be effected by orientating the direction in which the inertia reaction force is applied. In the form shown in Fig. 1, a plunger 4 is reciprocated in bearings 5, 6 fixed on a vehicle frame 9 and carries the armature 1 of a dynamoelectric machine, the stator 2 of which has axially-spaced field coils 3 and is carried by a spider framework 10 fixed to the frame 9. The plunger 4 also carries a framework 16 supporting a floating coil 15 which encircles the stator 2. After an initially free phase of the rearward stroke of the plunger 4, its kinetic energy is absorbed in. working the dynamo-electric machine so that it is brought to rest in relation to the vehicle at the rearward end of its stroke. The floating coil 15 is then energized by an accumulator, or by a separate generator driven by the engine, and reacts with the field coils 3 to motor the dynamo and assist in the return forward movement of the plunger 4. Alternatively, or additionally, this return movement may be effected or assisted by a coil spring, in which case the stator may be freely mounted and electromagnetically held in its correct longitudinal position. In a modification, the mobile body comprises a unidirectional friction shoe which, during its rearward stroke, is initially free and then engages a surface of high frictional resistance associated with steam coils or other heat-exchange devices. In the form shown in Fig. 4, a projector 31 driven by an engine 30 ejects liquid rearwardly along a longitudinal conduit 32 which opens into the upper limb 33 of an inert gas circuit in which the liquid evaporates. The liquid then condenses in the lower limb 34 cooled by coils 35, and flows forwardly along a return conduit 36 to the projector 31, the inert gas passing up through a conduit 37 heated by coils 38 to the upper limb 33. A similar circuit for a gaseous mobile body is described and illustrated in the Specification.
