TL;DR: In this paper, a diffuser is installed at the outlet of the afterburning chamber to feed freon into the discharged gas flow, which increases the capacity, head and fire-fighting efficiency of the generator.
Abstract: Installed at the outlet of the afterburning chamber is a diffuser whose narrow section forms a base for the afterburning chamber. The joint between the afterburning chamber and the diffuser is enclosed by a depression chamber which has a manifold with a circular slot for admitting compressed inert gas, e.g. nitrogen, from the outside. The diffuser accommodates a nozzle for feeding freon into the discharged gas flow. This increases the capacity, head and fire-fighting efficiency of the generator.

TL;DR: In this paper, a water hydrant diffuser consisting of a plurality of diffuser elements mounted in generally parallel planes in a housing is described, with a coupling section having a free end and a mating end with the free end being designed so that the coupling section can be secured to a water hyrant outlet.
Abstract: A water hydrant diffuser formed of a plurality of diffuser elements mounted in generally parallel planes in a housing. A coupling section has a free end and a mating end with the free end being designed so that the coupling section can be secured to a water hydrant outlet. The other end of the coupling section is connected to one end of the housing. A fluid flow measuring device can be inserted in the water hydrant diffuser intermediate the coupling section free end and the diffuser elements.

TL;DR: In this article, a spraying system for controlling air-borne particulate matter, such as coal dust, has a housing including a diverging diffuser portion into which a spray of liquid is injected.
Abstract: A spraying system for controlling air-borne particulate matter, such as coal dust, has a housing including a diverging diffuser portion into which a spray of liquid is injected. The spray causes a flow of air to pass into the diffuser portion and mix with the liquid to form a mist which passes from the diffuser portion to form a diverging jet downstream of the outlet of the diffuser portion. This diverging jet causes air molecules to be drawn into the mist and removed from the air through which the mist is passing.

TL;DR: In this article, a foldable diffuser for flash units mounted on photographic cameras is described, and a mechanism by which such a diffuser is moved automatically between collapsed and erected positions with respect to a flash unit mounting receptacle.
Abstract: A foldable diffuser for flash units mounted on photographic cameras and mechanism by which such a diffuser is moved automatically between collapsed and erected positions with respect to a flash unit mounting receptacle. The diffuser is pivoted on an axis normal to the front face of a shutter housing in a collapsible camera such that it lies against the front face in the folded position and swings out over a side face of the shutter housing in front of a flash unit mounted on the side face in the erected position. Movement to the collapsed position is effected by the erecting linkage of the camera against a pivotal bias on the diffuser.

TL;DR: A feeder for pneumatic conveyor installations used for milk powder and similar caking materials with a sugar or fat content introduces the compressed air at right angles to the material inlet pipe as discussed by the authors.
Abstract: A feeder for pneumatic conveyor installations used for milk powder and similar caking materials with a sugar or fat content introduces the compressed air at right angles to the material inlet pipe. After the compressed air inlet and before the material inlet, a porous disc, made of a material permeable to air (sintered metal powder) is arranged at an angle to both streams. The injection diffuser lies on the same centre line as the compressed air inlet. This ensures an extremely uniform air distribution over the whole section. Caking powder cannot form any crusts and produce blockages resulting in enforced stoppages.

TL;DR: In this article, the first results of an investigation designed to determine the most effective configurations for DAWT's and to assess their ultimate performance in large units are presented, and two types of compact diffusers have been analyzed and tested, using screens to simulate the turbines.
Abstract: The Diffuser-Augmented Wind Turbine (DAWT) is one of the more promising advanced concepts for decreasing the cost of wind energy conversion. The first results of an investigation designed to determine the most effective configurations for DAWT's and to assess their ultimate performance in large units are presented. Two types of compact diffusers have been analyzed and tested, using screens to simulate the turbines. A 20/sup 0/ half-angle conical diffuser with two tangential boundary layer control slots provided a measured augmentation ratio of 1.7 at an area ratio of 2.8, while a double ring-wing diffuser gave 2.1 at an equivalent area ratio of 3.8. Results indicate potential for considerable improvement and further size reduction. Several analyses related to diffuser development are given.
