IPC: C03C4/12
Filed: 1991-05-16
Abstract: Optical wave-guides, e.g. fibres, for use as photonic amplifiers have a path region partly or, preferably, wholly composed as a silica/germania glass with 0.1 to 5000 ppm mole of Er3+ as a lasing additive and alumina to adjust the bandwidth, the Ge:Al mole ratio being more than 2.8, e.g. 1:0.001 to 0.25. It is surprising that low amounts of alumina have a useful and significant effect on the lasing bandwidth whereby frequency division multiplex is facilitated.

Abstract: ABSTRACT OF THE DISCLOSURE Solute gas-rich absorbing media formed in scrubbing a solute gas from an off-gas stream prior to discharge of the same are regenerated to solute-lean absorbing medium for recycle to the scrubbing operation.  Hot rich absorbing  media  is  formed  into  one  or  more  spray patterns of very small  liquid droplets in a flowing purge steam stream in an elongate conduit into which the solute gas is desorbed from the droplets.  The droplets are coalesced to form a regenerated absorption medium, the  solute  gas-containing  gas  stream  is  cooled  to condense out the steam and a pure solute gas stream is recovered.   The operation may be effected in multiple stripping stages, which may comprise countercurrent flow of solute gas laden absorbing medium and purge steam within  a  single  conduit  or  in  multiple  conduits. Multiple stripping steps may be effected within a single stripping stage.

Title: Quick-and-slow speed screw drive mechanism
Inventor: FAN CHAOLAI
IPC: F16H25/24
Filed: 1994-04-25
Abstract: Abstract A quick-and-slow speed screw drive mechanism is composed of a supporting seat, a half nut (with inner threads less than half turn), an up-and-down sleeve (with up-and-down plate), a screw, a locking device, a spring and a pawl. The screw passes through the supporting holes of supporting seat and the holes of half nut and up-and-down sleeve 3 with the seat, integrating them as a whole. On the outer surface of half nut, guide surfaces are provided to match with the guide surfaces of supporting seat, cam profile is also provided to interact with the inner acting plane of up-and -down plate. When the screw rotates, through a pawl device, the up-and -down sleeve is brought to rotate with the screw, under the action of cam, the half nut is forced to make up-and-down movement, thus realizing the engagement and disengagement between the screw and the half nut, and enabling the screw to move axially with slow or quick speed.
