The present invention relates to a spinning apparatus (5) for producing a thread (36) by means of a circulating air flow, wherein the spinning apparatus (5) has a hollow spinning cone (19) which is arranged in a spinning housing (14, 15) and, in order to generate the circulating air flow, a nozzle block (17) which can be loaded with compressed air, wherein the spinning housing (14, 15) has an expansion chamber (28) which is provided with at least one waste air channel (29), wherein a compressed air source (22) can be connected to the waste air channel (29) for the joining operation, while the nozzle block can be separated from the compressed air supply, as a result of which an air flow which runs along the spinning cone (19) in the direction of the sliver guide (18) is generated in the spinning housing (14, 15), with the result that a suction effect is produced at the inlet opening (35) of the spinning cone (19), by way of which suction effect a thread (36) can be transported through the spinning cone (19) counter to the spinning direction.

A uniform flow control system for processing equipment with a plurality of work pieces located within the processing equipment, including a gas circulating device that circulates gas, a work chamber that can accommodate the plurality of work pieces and an expansion chamber that is located outside the work chamber and that guides gas to the work chamber. The expansion chamber includes a first chamber that extends along a first surface of the work chamber, a second chamber that extends along a second surface of the work chamber to a side of the first chamber, and a third chamber that extends from an end of the first chamber that is opposite the gas circulating device and below an end of the second chamber that is opposite the gas circulating device.

The invention discloses a wet-type nano-vortex dust cleaning apparatus and dust cleaning method. It mainly consists of furnace, gas liquid mixing chamber installed on the top of furnace, gas liquid spraying mouth on sidewall, gas liquid expansion chamber connected with gas liquid mixing chamber, vortex dust cleaner in gas liquid expansion chamber, desilter on the bottom of furnace and cleaned gas and cleaned liquid discharge tubes on the furnace. It is characterized by: the vortex dust cleaner consists of hollow diversion awl on top and vortex foam dust chamber on bottom; the walls composed said chamber is seam blades which are combined with a loop of curved triangle blade out the chamber; and the circulator laying under the chamber and connected with the chamber is equipped with cleaned gas discharge tubes and foam liquid discharge tubes; the method mainly consists of gas liquid mixing and expanding, vortex foam filtering and filter plate combined deducting steps, the dust collection efficiency of nano-ultra-fine dust which particle size below 0.2 mum reaches 99.95%, the exhausted gas liquid can be used cyclically without pollution.

A hooded muzzle brake for dissipating a recoil force created by the discharge of a firearm having a muzzle, while substantially decreasing the noise heard by the shooter, resulting in a reduced muzzle flash signature and the attendant dust cloud generated by typical muzzle brake devices for use in the field or military applications. The muzzle brake is an enclosed device with at least one opening radially disposed from a central bore. The radial opening(s) help to dissipate recoil force-causing gasses away from the muzzle end of a firearm with limited reflection of gasses back towards the shooter since the gases are contained by the hood of the muzzle brake in the expansion chamber(s). The Hooded muzzle brake may have more than a single expansion chamber to allow the hot gasses to expand internally, compressing the oxygenated air within, allowing any unburned gunpowder to burn more completely during a short expansion and cooling before being diverted 90 degrees and released less explosively out the front of the muzzle brake through forward facing gas port(s) and the muzzle and away from the shooter. This metered delay of the expanding combustion gasses decrease the perceived recoil, the muzzle flash signature, dust cloud signature blown into the air associated with traditional muzzle brakes, the amount of gas reflected back toward the shooter, and the amount of noise the shooter hears.
