This invention provides a healthcare cum optimal illumination device. The inventive device includes at least one frame, at least one light source, and at least one layer of treated filter cover. The light source is disposed in the frame. The light source emits infrared radiation, visible light radiation, and ultraviolet radiation. The visible radiation is used for illumination, and the invisible infrared and ultraviolet radiation is harnessed to improve indoor air quality. The layer of the filter cover is treated with substances of air cleaning properties and encloses the frame. The treated filter cover has at least one opening where air in the frame heated by the infrared radiation flows out from the device and cooler ambient air surrounding the device is drawn through the filter cover into the frame replacing the heated air that has flown out of the device to form air circulation and to perform air purification.

The invention relates to a process for producing respirable air comprising the following stages: treatment of compressed air comprising an air-drying operation; and rehumidification of the treated dry air. According to the invention, the rehumidification stage of the treated dry air comprises an operation of controlled distribution of the treated dry air on the one hand in a rehumidification line (24), and on the other hand in a dry line (22). The invention also relates to an installation (1) for utilising such a process. Application to the area of nuclear installation dismantling.

The present invention relates to a sealed and ventilated receptacle for storing equipment, such as firefighter turnout gear, that generally includes a base, at least one sidewall extending from the base, and a top wall that covers the opposite end of the sidewall. A sealable door may be positioned on the sidewall to access the inside of the receptacle and to prevent any contaminants from exiting the receptacle. The receptacle may also include an intake fan and exhaust fan that are each connected to a duct for providing fresh air to and removing contaminated air from the inside of the receptacle. The receptacle may further include a temperature control unit for regulating the temperature inside of the receptacle. Additionally, a hook for hanging a firefighter coat, trousers, or other items may also be included on the inside of the receptacle.

High Q-value radio frequency (RF] coils are described. In general, the RF coils include multiple conductor layers that at least partially overlap to define a capacitive region that equalizes current flowing in each conductor. In some instances, the RF coil includes sets of layered conductors, where each set of layered conductors overlaps in an overlap region. In some other instances, the RF coil includes a spiraled conductor coupled to a dielectric material, where the number of turns of the spiral defines the overlap area. Multiple spiraled conductors can be interleaved. An equalization coil can also be provided to equalize currents along an axial dimension of each conductor in such RF coils. The thickness of the conductors is less than three skin depths, and preferably less than one skin depth, to overcome skin-depth limitations.

The invention discloses a technology for emergency treatment of environmental pollution caused by fires and leakage. The technology comprises a machine body; an auxiliary power cavity is arranged in the machine body; a moving cavity is disposed in the bottom side of the auxiliary power cavity; a belt hole is formed in the right side wall of the moving cavity; a cleaning cavity is disposed in the right side wall of the belt hole; the moving cavity communicates with the cleaning cavity; a diffusion cavity is disposed in the right side wall of the cleaning cavity; a restoration cavity is disposedin the bottom side wall of the cleaning cavity; a main power cavity is disposed in the top side of the cleaning cavity; and a storing cavity is disposed in the top side of the main power cavity. A main motor is started to drive a first power shaft so as to drive a first bevel gear, a moving shaft and a sliding block to rotate, then a baffle moves backwards, meanwhile sand in the storing cavity flows out of a sand discharging hole, the baffle leaves a rear spring, diffusion is prevented so as to avoid great harm, meanwhile the sand stored in a device is released along with opening of a partition board so as to cover leaked harmful liquid, and burning and diffusion of the liquid are prevented.

The present invention relates to fire evacuation shelter facilities, and particularly, to fire evacuation shelter facilities that enable persons who were unable to escape from a fire via an emergency exit or other escape means to be safely protected from flames and noxious fumes until firefighters or other rescuers arrive.

The invention discloses a fireman escape device for forest fire fighting and relates to the field of fire-fighting escape. The fireman escape device for forest fire fighting comprises a main supporting plate frame, an expansion supporting framework and a protection cloth covering. The expansion supporting framework is arranged on the left side surface of the main supporting plate frame. The expansion supporting framework comprises a plurality of supporting frames and expansion connecting rod sets. Each expansion connecting rod set is composed of connecting rod hinge seats and connecting rod supports. The protection cloth covering is wrapped outside the plurality of supporting frames. According to the fireman escape device for forest fire fighting, the main supporting plate frame is provided with the expansion supporting framework, and the protection cloth covering is wrapped outside the expansion supporting framework; an escape person can go into the protection cloth covering to be prevented from being burnt by flames; the fireman escape device is pulled through a handle bar, rolls through two rolling wheels at the lower end of the main supporting plate frame and the road surface and is convenient to carry and move. Shoulder clasps are used for clasping the shoulders of the escape person to be carried on the back. A waistband is tied on the waist of the carrying person. The situation that the fireman escape device is inconvenient to carry on a mountain road in the forest is avoided.
