While such systems and methods can include any suitable component, in some cases, they include a first and a second piece of sauna housing and a sauna heater. In some such cases, the second piece of sauna housing slidingly couples with the first piece to define an interior sauna chamber. Additionally, in some cases, a first portion of the second piece of sauna housing is configured to slidably fit within the first piece such that a volume of the sauna chamber is configured to increase and decrease, respectively, when the second piece is moved into an extended position or when the second piece is moved from the extended position into a collapsed position in which the second piece nests within the first piece. In some cases, the first and second pieces include a ceiling that is configured to extend over a user within the sauna chamber. Other implementations are described.

The invention discloses a rapid drawing opened-closed type anti-explosion ball. The anti-explosion ball comprises an upper half ball and a lower half ball which are fixedly connected. A throwing-in port is formed in the upper half ball and provided with a protection sealing cover. The protection sealing cover and the upper half ball are in drawing connection through an industrial guide rail. A locking mechanism is arranged in the protection sealing cover. The upper half ball is provided with a locking hole matched with the locking mechanism. A weak explosion buffering layer is arranged in the protection sealing cover. The anti-explosion ball is arranged on a circular ball support. The bottom end of the circular ball support is fixedly connected with a butterfly-shaped half ball weak explosion buffering layer. The weak explosion buffering layer and the butterfly-shaped half ball weak explosion buffering layer are filled with weak explosion anti-explosion materials. The anti-explosion ball is rapidly opened and closed, and is good in anti-explosion performance, large in inner size and capable of being used for storing large suspected explosives.

The invention discloses an inorganic silicon-aluminum dry-powder paint for an exterior wall. The paint is composed of powder and water and is characterized in that a weight ratio of the powder to water is 1: 0.2 to 1: 0.6; and the powder comprises, by weight, natural resin, a sal material, a fibrous material, quartz powder, sand, sulfonated hyperbranched polypyrrolone-modified graphene oxide, polybenzimidazole-modified meso-porous silicon, KH-560 and inorganic pigment. The inorganic silicon-aluminum dry-powder paint is eco-environment friendly, does not contain volatile harmful substances like VOCs, formaldehyde and ammonia, has ultra-long service life which is identical to the service life of the wall, and has excellent weatherability, acid and alkali resistance, anti-powdering performance, color retention performance, temperature and humidity adjustment performance and ecological functionality, and good construction operability.

The invention discloses a thick steel-structure fireproof radiation protective paint which consists of powder and water according to the weight ratio of (1:0.6)-(1:1.5), wherein the powder comprises the components of a fireproof filling material, a main bonding agent, an auxiliary bonding agent, wollastonite powder, mica powder, diamino polyethylene glycol modified hyperbranched polypyrrolone, polybenzimidazole modified meso-porous silicon, KH-560 and graphene oxide. The thick steel-structure fireproof radiation protective paint has the characteristics of being waterproof, anti-seepage, fireproof, impact resistant, simple in processing process, convenient to construct, non-toxic, harmless, long in service life, good in radiation protection performance and the like.

The invention relates to a silencer device for a firearm, in particular for a rifle or another long or short firearm, and to a silencing method, said device comprising: a flap mechanism (10) comprising at least one closing flap (10) mounted transversely to the axis on the barrel (42) of the firearm in order to temporarily seal the barrel after ammunition has passed through and to prevent the passage of the combustion gases and the sound wave towards the mouth of the barrel when a shot is fired; and an actuating unit (31,34,35) comprising a mobile part (31) arranged axially on the barrel of thefirearm in order to move a control mechanism (6), where the mobile part (31) axially comprises an inner borehole for allowing ammunition to pass through, the control mechanism (6) includes at least one amplitude lever arm (8) pivotably mounted on a pivot (7) attached to the barrel, and each amplitude lever arm (8) is respectively coupled to a closing flap (10), the mobile actuating unit (31,34,35) cooperating with the control mechanism (6) to allow a transverse movement of said at least one closing flap (10) between an open position in which the flap mechanism (10) allows ammunition to pass towards the mouth of the barrel (42) and a closed position preventing the passage of the combustion gases and the sound wave after the ammunition has passed through; and an exhaust unit (11, 21-27) including at least one exhaust pipe (11, 21) arranged on the barrel upstream from the closing flap mechanism (10) in order to redirect the combustion gases and the sound wave and allow them to leave thebarrel.
