A vacuum cleaner includes a cleaner body, a suction brush, through which air and contaminants are drawn in, and a cyclone type dust collecting device. The cleaner body has a motor driving chamber and a dust collecting chamber in communication with the motor driving chamber. The cyclone type dust collecting device is mounted in the dust collecting chamber and separates by centrifugal force the contaminants from the air. The cyclone type dust collecting device includes a hollow cylindrical cyclone body having an open top, a closed bottom, and a contaminant outlet. The open top allows air and contaminants into the cyclone body, where the contaminants are separated from the air by centrifugation. The contaminants are then discharged from the cyclone body through the contaminant outlet. The cyclone type dust collecting device further includes a contaminant receptacle for collecting the contaminants discharged through the contaminant outlet, a base member hingedly connected to the contaminant receptacle, and a cover for covering the top of the cyclone body. The cover has an air inlet passage, through which air and contaminants drawn in through the suction brush enter into the cyclone body, an air outlet passage, through which the air is discharged from the cyclone body, and a contaminant separating grill. The grill extends downward from the air outlet passage into the cyclone body and has a plurality of fine holes.

A hand-held rebreather/breathing apparatus for high altitude pre-acclimatization and training. Air exhaled by a user is directed to a reservoir bag for cooling and condensate collection. At inhalation negative pressure created a mixing chamber forces the air stored in the reservoir bag to pass via CO2 absorption chamber where it may be mixed with a fresh portion of the ambient air that influxes via orifice(s) communicating with this chamber. Baseline of the minimum oxygen concentration in inspired air can be pre-set by means of adjustment of the maximum volume of the reservoir bag and/or by means of altering of the number or diameter of one or a plurality of orifices for commination of the ambient air. Biofeedback may be provided by an oxygen monitor.

An exhausting and cooling system for a cooking utensil, which exhausts gas or smoke generated during a cooking process and cools a lower portion of a grill. The exhausting and cooling system for the cooking utensil, which has a main body provided with a grill unit mounted on the upper surface thereof, includes an exhaust channel and an exhaust fan for inhaling air around the grill unit and exhausting the air downwardly; and a cooling channel and a cooling fan for blowing external air to the lower portion of the grill unit to cool the lower portion of the grill unit.

A cooling system of the invention mounted on a motor vehicle has a damper configured to switch over an air blow mode between an inside air intake mode of taking in the air from a passenger compartment of the motor vehicle via operation of a battery blower fan and directly blowing the intake air to a battery and an A/C intake mode of taking in the air cooled down by an air conditioner (evaporator) via operation of the battery blower fan and blowing the cooled intake air to the battery. In response to a switchover demand of the air blow mode, when a vehicle speed is not lower than a preset reference speed, a switchover of the damper is immediately performed to switch over the air blow mode. When the vehicle speed is lower than the preset reference speed, the switchover of the damper is prohibited to keep the air blow mode unchanged. At the higher vehicle speed, the drive-related noise (background noise) sufficiently masks the wind noise occurring in the course of the switchover of the damper. The damper is thus switched over only at the vehicle speed of not lower than the preset reference speed. This arrangement effectively prevents the driver and the other passengers from feeling odd and uncomfortable.

Passive removal of suction air for producing a laminar flow, and associated systems and methods are disclosed. One such method includes forming a laminar flow region over an external surface of an aircraft by drawing air through the external surface and into a plenum. The method can further include passively directing the air from the plenum overboard the aircraft. For example, the air can be passively directed to a region external to the aircraft having a static pressure lower than a static pressure in the plenum, as a result of the motion of the aircraft. Flows from different sections of the external surface can be combined in a common plenum, and the corresponding massflow rates can be controlled by the local porosity of the external surface.

A projectile launcher has a magazine of launching chambers for holding a plurality of projectiles at the launcher's front end. The projectiles are launchable by the delivery of a blast of compressed air through each chamber's respective air inlet. The air inlets are uniformly spaced in a substantially cylindrical array about the magazine. A piston with a handle is adjacent to the rear end of the launcher body. The piston has a longitudinal axis coaxial with the cylindrical array, and the piston is movable in back-stroke and fore-stroke motions along that axis for inhaling air into the launcher during the back-stroke and exhaling air from the launcher though one of said air inlets in blasts of compressed air during the fore-stroke. A rotatable diverter directs the blasts to one of the air inlets individually and sequentially upon successive backstroke and fore-stroke cycles of the piston.
