Title: I.c. engine cylinder head intake passage with means for atomizing fuel droplets
Inventor: SMITH JR RICHARD W
IPC: F02F1/24
Filed: 1994-09-28
Abstract: In order to provide better atomization of the fuel/air mixture, the intake passage 83 has a choke 99 to increase flow velocity upstream of a protuberance 96 which extends into the incoming fuel/air flow area and has a trailing end in the form of a knife-edge 98 (note that fig. 12 shows a cast of the passage, so that eg the protuberance appears as a recess). Just downstream of the choke 99, the passage 83 undergoes a sharp change in direction before entering the intake wedge portion 69 of the combustion chamber 65; this causes entrained fuel droplets to impact on, and thus become fragmented by, a reaction surface 100 on the protuberance 96. The fragmented droplets are vaporised by a shearing action across the knife-edge 98. A pocket 101 located immediately downstream of the knife-edge 98 causes turbulence which improves fuel/air mixing.

Title: An efficient dispersion and loss compensating wavelength division demultiplexer
Inventor: OTANI TOMOHIRO
IPC: H04B10/29
Filed: 1997-11-07
Abstract: In the demultiplexer device 19, couplers 20-22 are disposed in multi stages. To one branch of each coupler, optical bandpass filters 15-17 are connected. To the other branches, equalizing fibers 2, 23-25 are connected. The final equalizing fibre 25 has an additional optical filter 18, for the shortest wavelength signal, connected. Optical amplifiers 3, 26 are disposed at predetermined points. If a wavelength division multiplexed signal is inputted at point 1, dispersion and loss compensated demultiplexed signals S1-S4 are outputted as shown. This arrangement means that the equalizing fibers 2, 23-25 act to perform accumulative dispersion compensation. Consequently, the number of equalizing fibres required is reduced, resulting in less attenuation allowing the number of optical amplifiers to be reduced as well. Thus the device achieves efficient dispersion and loss compensation using less optical components. The filters 15-18 may be dielectric filters or optical circulator/fibre grating combinations.
