Fan assembly for vacuum cleaner

Abstract: A fan assembly for a vacuum cleaner, comprising a motor, an impeller rotatably coupled to the motor, and having a plurality of impeller wings, and a diffuser having a plurality of diffuser wings arranged along an outer circumference of the impeller. The plurality of diffuser wings includes first and second parts, the second part extending from an angle of the first part adjacent to the outer circumference of the impeller.

Self-automated mushroom growing system

Abstract: A self-automated mushroom growing apparatus and method for providing a continuous water and air supply for growing mushrooms on a small-scale. The apparatus is an enclosed, terrarium-like Grow Space including a porous Wicking Medium substrate, and an Air Diffuser rod situated within or below the porous Wicking Medium. An Air Diffuser is situated within the apparatus and is connected to an air supply to provide fresh air to the Grow Space. The porous Wicking Medium is saturated with water. The saturated Wicking Medium provides a continuous supply of water to a Cake Culture in contact with the Wicking Medium. The Air Supply mixes stale air that settles near the surface of the porous Wicking Medium.

Combination acoustic diffuser and absorber and method of production thereof

Abstract: The present invention relates to a combination acoustic diffuser and absorber and method of production thereof. The diffuser has an acoustically reflective surface that may be made by the vacuum forming of pliable sheet material in conformity with a shaped template and the subsequent fixing of the resulting shape of said material, and which surface includes a plurality of wells, the depths of which wells may be determined by number theory sequences. The absorber may include one or more tunable Helmholtz resonators which may be attached to the rear face of the diffusing surface. The combination acoustic diffuser and absorber may be optimized in its function and construction for use in a typical residential application. A kit may also be provided that comprises a diffuser, absorbers, mounting hardware, and assembly and adjustment instructions.

The design and analysis of pipe diffusers for centrifugal compressors

Abstract: The geometry of the region between the impeller tip and diffuser throat is accepted as being very influential, little understood and crucial to the performance of centrifugal compressors. T...

Controllable diffuser for an air intake of an aircraft

Abstract: A diffuser for an air intake of an aircraft has an inlet and an outlet, both with variable cross-sectional flow areas. At least one wall section of a diffuser defining flow channel is movable by one or separate lever linkage systems for varying the inlet and outlet cross-sectional flow areas. A control circuit, preferably a closed loop control circuit responsive to a control program, makes sure that optimal flow cross-sectional areas are maintained at the inlet and outlet of the diffuser to optimize the operation of the diffuser.
