TL;DR: In this article, the authors describe an apparatus and process for producing polymeric foam, wherein reactive foam components and a low-boiling point frothing agent are brought together, sufficient pressure is applied to maintain the foam in a liquid state and the mixture is passed through a permeable discharge head through which the mixture was discharged and wherein the pressure is reduced and froth is formed.
Abstract: An apparatus and process for producing polymeric foam, wherein reactive foam components and a low-boiling point frothing agent are brought together, sufficient pressure is applied to maintain the frothing agent in a liquid state and the mixture is passed through a permeable discharge head through which the mixture is discharged and wherein the pressure is reduced and froth is formed. The discharge head comprises one or more diffuser elements (80) having a structure such as to require division, divergence and convergence of flow paths in three dimensions within the axial thickness of the diffuser element, considered in the direction of flow therethrough. The diffuser element (80) is made of bonded, or sintered or sintered composite material, such as sintered wire.

TL;DR: In this article, a hand-held hair dryer including a handle, a body connected to the handle portion, a barrel connected to body portion and having an inner member defining a first air passageway, an outer member slidingably coupled to the inner member and defining a second air passage that is substantially parallel to the first air passage is described.
Abstract: A hand-held hair dryer including a handle, a body connected to the handle portion, a barrel connected to the body portion and having an inner member defining a first air passageway, an outer member slidably coupled to the inner member and defining a second air passageway that is substantially parallel to the first air passageway, a shutter coupled to the inner member and movable in response to sliding of the outer member with respect to the inner member to selectively direct air through the first air passageway and the second air passageway.

05 Dec 2000TL;DR: In this article, an anode is contained within the electrolyte cell and a porous rigid diffuser is connected to the anode and extends across the cell, which is positioned between a location that the substrate is to be positioned when the metal film is deposited thereon.
Abstract: An apparatus comprising an electrolyte cell, an anode, and a porous rigid diffuser. The electrolyte cell is configured to receive a substrate to have a metal film deposited thereon. An anode is contained within the electrolyte cell. A porous rigid diffuser is connected to the electrolyte cell and extends across the electrolyte cell. The diffuser is positioned between a location that the substrate is to be positioned when the metal film is deposited thereon and the anode.
