Patent GB-2236963-A (GB)
Title: Gas distribution apparatus
Inventor: HUFTON PETER F
IPC: B01J8/44
Filed: 1990-10-17
Abstract: The fluidizing flow to a fluid bed (B) is distributed to the bed by a series of fluidic control devices such as venturi devices (4). Between a gas supply channel and the bed there is a closed plenum chamber through which the devices extend. Control porting (28) connects the plenum chamber with the throats of the venturi devices, so that a drop of throat pressure in any one device relative to the others induces a flow into the venturi throat from the plenum chamber. That control flow causes separation in the diffuser region of the device, increasing the resistance to flow through the device. In this way, local pressure variations in the bed can be limited and smoothed. <IMAGE>

Title: Audio mirror speaker
Inventor: YAGISAWA TOSHIHIRO
IPC: H04R1/34
Filed: 1991-01-22
Abstract: In an audio mirror speaker, an uneven area 2 is formed on a planar mirror surface 1 and the directivity distribution is controlled by changing the relative position of a speaker diaphragm 3 facing the mirror surface and the mirror. The directivity distribution of such a speaker is determined by the radius of curvature of the uneven area. Since the directivity changes with movements of the planar mirror, freedom in setting the directivity distribution is enhanced. <IMAGE>
