A smoke producing method and device of the present disclosure produces a non-incendiary, organic-polymerization based, smoke-producing reaction. Some versions of the smoke are effective carriers for capsaicinoid compounds. The method of generating smoke comprises initiating a frontal polymerization reaction by heating a composition comprising a monomer compound that exothermically polymerizes upon initiation with an initiator compound and an initiator compound that initiates polymerization of the monomer compound present at a mass concentration that is at least five percent of the mass concentration of the monomer compound. The polymerization of the monomer compound is exothermic, and in one embodiment the concentration of initiator compound is at least five percent of the concentration of monomer compound. The smoke mainly comprises thermal decomposition products of the initiator compound.

Capsaicinoid smoke

A double valve having inlet, outlet, and exhaust ports maintains an outlet pressure below one percent of inlet pressure during a faulted state while maintaining a relatively small exhaust for reduced overall valve size. Crossover passages receive inlet pressure through main crossover poppets when the respective valve units are not in a deactuated position. When the valve units are in a deactuated position, then the crossover passages receive inlet pressure through respective bypass passages whose flow rate can be controlled independently from the size of the crossover poppets. The use of bypass passages provides particular benefits for double valves for non-press applications which have a ratio of exhaust flow coefficient to inlet flow coefficient that is less than about 2.5.

High throughput double valve with reduced outlet pressure during a faulted state

A control valve apparatus couples pressurized fluid to first and second actuators using first and second double valves. The first double valve includes first and second crossover passages and first and second pilots. The second double valve includes third and fourth crossover passages and third and fourth pilots. A first interconnection couples the first crossover passage with the third pilot fluid inlet. A second interconnection couples the second crossover passage with the fourth pilot fluid inlet. A third interconnection couples the third crossover passage with the first pilot fluid inlet. A fourth interconnection couples the fourth crossover passage with the second pilot fluid inlet. Thus, operation of each pilot depends upon receiving pressurized fluid from the other double valve which is only present when the other double valve is not in a fault condition.

Dynamic fluid power monitoring system for separate actuators

A double valve is reset when a source of pressurized fluid is connected to a reset port. When the source of pressurized fluid is removed from the reset port, a first reset piston is retracted so that a second pilot chamber receives pressurized fluid while a first pilot chamber continues to be vented. A second reset piston is retracted after a predetermined delay time following retraction of the first reset piston, the predetermined delay time being sufficient to allow the second pilot chamber to become substantially pressurized. If a second pilot valve is actuated when the second reset piston is retracted, then the pressurized fluid in the second pilot chamber drives the second movable valve unit out of a deactuated position during a time that pressurized fluid in the first pilot chamber is insufficient to drive the first movable valve unit out of a deactuated position.

Dynamically-monitored double valve with anti-tiedown feature

A double valve for controlling a machine tool has a memory such that when the valve is in its normal deactuated state and the inlet air supply is cycled (e.g., turned from on to off or from off to on), then the valve remains in the deactuated (i.e., ready to run) state. When the valve is in a faulted state (e.g., intermediate position) and the inlet air supply is cycled, then the valve remains in the faulted state. The memory is achieved by a balanced condition of the movable valve elements when in the normal deactuated position and an unbalanced or latched condition when in the intermediate or faulted position.

Dynamically-monitored double valve with retained memory of valve states

A kneeling valve assembly for transport vehicles to enable a quick and convenient kneeling operation to permit safe ingress and egress from the vehicle. The kneeling valve assembly employs a suspension member positioned between the vehicle body and the axle of the transport vehicle to raise and lower the transport vehicle relative to a ground level. The kneeling valve assembly includes a first valve that is operable to selectively permit fluid flow between the inlet passage and the suspension member to raise the transport vehicle relative to the ground level. A second valve is provided that is operable to selectively permit fluid flow between the suspension member and the exhaust passage to lower the transport vehicle relative to the ground level. A leveling trigger is fluidly coupled to the inlet passage and is operable to determine a height of the transport vehicle relative to the ground level. Finally, a third valve is provided that is operable to selectively permit fluid flow between the inlet passage and the suspension member to maintain a predetermined height above the ground level.

Kneeling valve

A pneumatic control system is provided for selectively controlling movement of a pneumatically-operated device between first and second working positions. The pneumatically-operated device includes a working portion and a pneumatic-control portion. The pneumatic-control portion is in fluid communication with a pressurized fluid source and includes a series of valves for selectively manipulating the working portion between the first and second working positions. The pneumatic-control portion further includes a sensing system for holding the working portion in a static mode by selectively applying system pressure to the working portion. In this manner, a more energy efficient system is provided by eliminating the need for continuous application of full line pressure.

Low energy and non-heat transferring crust breaking system

A control valve system having a housing defining an inlet, an outlet, and an exhaust. A first passage extends between the inlet and the outlet and a second passage extends between the outlet and the exhaust. The control valve system includes a first valve disposed within the first passage. The first valve is movable between a closed position and an opened position. Similarly, the control valve system includes a second valve disposed within the second passage. The second valve is movable between a closed position and an opened position. Furthermore, the control valve system includes a regulator circuit operably coupled to the housing, which outputs a pilot pressure in response to an inlet pressure. An actuating member is slidably disposed within the housing and moveable in response to a pressure differential between the outlet and the pilot pressure. The actuating member independently actuates the first valve and the second valve to provide a quick pressure and exhaust feature.

Variable pressure control device

A pneumatic control system for a freight car having a brake pipe, auxiliary and emergency reservoirs normally charged with pressurized fluid from the brake pipe, a fluid pressure activated brake cylinder device and an exhaust including an electronic controller, at least one pressure sensor, an electrically operated supply valve controlled by the electronic controller selectively communicating the brake cylinder with one of the reservoirs to perform a brake application, an exhaust valve selectively communicating the brake cylinder with the atmosphere thereby performing a brake release function, and an electronically operated exhaust latching valve controlled by the electronic controller to selectively signal the exhaust valve to connect the brake cylinder to the exhaust.

A water distributor for distributing a flow of water to at least one of a plurality of output ports. The particular output port(s) chosen varies as a function of time and depends on the position of a motor driven rotor within the distributor. In another embodiment of the invention the distributor distributes water to at least one of a plurality of nozzles and draws water through at least one of the same plurality of nozzles. Other ones of the plurality of nozzles are neither outputting nor drawing in water. The function of a particular nozzle is dependent on the position of a rotor within the distributor. The rotor is motor driven whereby the function of a particular nozzle changes as a function of time as the rotor rotates. Each distributor of the invention is particularly adaptable for coupling to a fluid filled tank to provide time varying currents and eddies. The distributors thus provide a varying flow of water to a tank to disperse pollutants and contaminants and provide oxygen to the water.
