Provided is a smoke machine that comprises a heating element disposed within a chamber wherein smoke is created. The chamber may contain a liquid reservoir containing a liquid that creates visible smoke when heated, e.g. to the point of vaporization, evaporation and/or condensation. A liquid transfer device transfers the liquid from the reservoir towards the heating element. The liquid transfer device may be provided around the periphery of the heating element, e.g. by being wrapped or coiled around it, of by having the heating element inserted in it. It may be tied in place or fastened by a fastener. It may be held by friction fit provided by a friction allowing wicking but providing substantially complete coverage of the heating element or part thereof. Also provided is a smoke machine that comprises a pressure controller.

This disclosure relates generally to a Multiple Payload Expendable Device consisting of a set of cylindrical multiple payload casings, each payload casing exhibiting circular symmetry fluid passages in relation to firing squibs and voltage coded squib actuating circuit that converts existing single payload expendable device systems to multiple payload expendable device systems.

A fogger comprises a blower tube having a passageway, a fan configured to rotate to generate an airflow through the passageway, a reservoir configured to hold a volume of fluid and a volume of air, an air pump in fluid communication with the fluid in the reservoir, a motor configured to drive the fan and the air pump, an atomizing valve, a dispensing line fluidly coupling the atomizing valve to the passageway, a liquid tube fluidly coupling the fluid in the reservoir to the atomizing valve, and an air escape line fluidly coupling the air in the reservoir to the atomizing valve. In response to the air pump providing a stream of compressed air to the reservoir, air moves through the air escape line from the reservoir to the atomizing valve, such that fluid is drawn through the liquid tube and into the atomizing valve to be atomized.

A visibility-impairing security device is disclosed for producing a gathering of air-suspended light-obscuring matter to obscure vision. The device comprises a body comprising an emission unit receiving portion for holding an emission unit having an outlet for emitting the matter; an opening for the passing therethrough of the matter from the outlet; and a door for closing the opening. The door is configured to move between a closed position in which the opening is covered and an open position in which the opening is at least partially open, thus allowing for the passing therethrough of the matter from the outlet when the door is in the open position.

A mixture and method of creating the mixture includes mixing hexachloroethane, stannous oxide, and aluminum together. The mixture may be loaded into at least one canister. The mixture may be combusted to create a smoke screen. The loading of the mixture into the at least one canister may include pressurized loading at loading pressures in the range of approximately 2300 psi to 3600 psi. The hexachloroethane may include approximately 30-40 parts by weight of the mixture and have a particle size of approximately less than 850 m. The stannous oxide may include approximately 55-65 parts by weight of the mixture and have a particle size of approximately less than 150 m. The aluminum may include approximately 5-10 parts by weight of the mixture and have a particle size of approximately less than 45 m. The mixture is devoid of zinc chloride.
