Abstract: Recovery of the catalyst system i.e. a platinum group catalyst, a co-catalyst, a quat. salt and a base) from an ROH oxidative carbonylation reaction mixture containing 20-70 wt.% diaryl carbonate of formula R-O-CO-O-R (I) (R = optionally substituted 6-15C aryl) comprises: (a) transferring the reaction solution from the reactor to a vessel where it is suspension crystallised by cooling; (b) separating the crystallisate comprising mainly (I) and the ROH starting material from the remaining catalyst-containing mother liquor; (c) working the crystallisate up into pure (I) and pure ROH and (d) recycling the mother liquor to the reactor or working it up to recover the various components. The cooling of the reaction solution is preferably at 20-0.1K/hr and is accompanied by seeding with solid (I) and/or solid ROH, the seeding material being used at 0.02-1 wt.% based on the amount of (I) in the reaction solution. Following step (b), the crystallisate is washed with a water-free wash solution, especially solution containing a (I)/ROH mixture or just ROH, with the solution recycled to the reactor. An especially preferred wash solution is a 10-25 wt.% solution of (I) in ROH used in an amount of 50-250 pts. wt. per 100 pts. wt. of the crystallisate, with the crystallisate slurried with 25-40 wt.% of the wash solution and filtered and then slurried again with the remaining wash solution and filtered again.

Abstract: The manual correction mechanism includes a day indicator (2), an hour hand and a minute hand. The mechanism has a first device (10) which can be coupled to the day indicator (2) so as to permit adjustment of the day display. The mechanism has also a second device (11) which can also be coupled to the day indicator (2) for day, hour and minute adjustment. The second device (11) has device (12) for decoupling the day indicator (2) when the first device drive the day indicator. The day indicator is a toothed ring and the second device (11) is a movement having a first star wheel (13) designed to mesh with a the teeth (14) of the ring (2) and a second star wheel (15) which meshes with a finger (16) carried on an intermediate wheel(17) which in its turn meshed with the hour wheel (18). The decoupler consists of a plate (12) reset by a leaf spring(19) supporting the device (11). This plate (12) is mounted so that it pivots on an axis (6) around which turns the intermediate wheel (17). The device (11) can be in an engaged position under the action of the leaf spring (19) or a disengaged position in which the first star wheel (13) no longer engages the teeth (14) of the ring (2) when the first device (10) is actuated. The teeth of the ring push the teeth of the first star wheel outside the trajectory of the ring teeth at against the action of the leaf spring (19) force.

Abstract: A chin fixing apparatus rarely causing a user to have
physical disorder during the use thereof and capable of reliably
preventing the chin from moving back while the user sleeps.
The chin fixing apparatus comprises a fixing piece and a filler.
The fixing piece has an outer wall portion, an inner wall portion
and a partition wall portion which are combined so as to have a
substantially H-shaped cross section, whereby grooves for
receiving parts of rows of teeth are formed on the upper and
lower sides of the partition wall portion. Vertically extending
through bores are formed in the partition wall portion. The filler
can comprise a composition harmless to a human body and
changing from the state of paste of a high viscosity into the state
of gel having an elasticity in a short period of time. The fixing
piece with the filler packed therein is bitten by the upper and
lower teeth, which are bound together owing to the
solidification of the filler, whereby the backward displacement
of the chin is prevented.

Abstract: L'invention porte sur une attraction foraine aquatique comprenant un canal (2) d'eau, relié à une zone de plage (22), et dans laquelle un flux torrentiel d'eau peut être déversé dans le canal de sorte qu'une houle (50) qui traverse le canal puis se transforme en une vague unique (51) qui se déverse vient se briser sur la plage. L'eau du canal peut également être amenée à s'écouler dans une direction uniforme (11) en raison de son impulsion, et de l'énergie transférée lors des déversements répétés du flot torrentiel dans le canal. La courbure et l'orientation de la zone de plage par rapport au canal amènent les vagues se brisant sur la plage à se diriger radialement vers l'extérieur en formant un arc, ce qui les amène à déborder et à se briser lors de leur trajectoire autour de la plage.
