Inventor: BERGOUGNAN MICHEL
IPC: C07C17/20
Filed: 1990-09-20
Granted: 1995-09-19
Abstract: Continuous manufacture of 1,1,1-chlorodifluoroethane from 1,1,1-trichloroethane and hydrofluoric acid by liquid phase reaction in the presence of at least one fluorination catalyst. According to the invention the operation is carried out at an absolute pressure of between 6 and 30 bars and at a temperature of between 50 and 120 DEG C, the catalyst content of the reaction mixture, expressed as weight percentage of metal, being between 0.05 and 10% and its content of organohalogen by-products outside 140 series being regulated at a value of less than 40% by weight. This process makes it possible simultaneously to obtain a high degree of conversion of hydrofluoric acid, to minimise the coproduction of 1,1,1-trifluoroethane and of organohalogen by-products, and to make it easier to recover the hydrochloric acid formed.

Granted: 1996-03-19
Abstract: In order to regulate dewatering of the fiber suspension and the formation of the paper web between the upper and lower wires of the papermaking machines, upper ledges are provided along  with  the  upper  wire.    These  upper ledges  are particularly  constructed  so  as  to  have  uniform  design. Between these upper ledges,  there is left free the same distance or spacing.  This distance is not smaller than the width of each upper ledge.  The individual distances between the upper ledges can be closed by insertable inserts so that the dewatering  can be  forcibly  accomplished at mutually separated zones.  Along the lower wire, there are provided lower ledges at a table, and between these lower ledges, it can be adjusted varying distances or spacing therebetween. The mutual distance or spacing between the lower ledges, according to a favorable construction, is always greater than the width of the individual upper ledges plus the distance or spacing of an upper ledge from the next neighboring upper ledge.  The lower ledges can be mounted at the table so as to be lengthwise displaceably and individually adjustable in the direction of the lower wire.   The table can be selectably positioned vertically as well as horizontally relative to the lower wire.  All of these measures also can be accomplished during operation of the papermaking machine.  The individual lower ledges are elastically supported against the table and this table is elastically supported against its foundation. It is possible to undertake the web forming operation, during operation of the papermaking machines,  in accordance with technological  requirements and the time wise as well  as localized situations, while protecting the paper web which is to be  formed and  equally the  equipment which  is to be operated.

Granted: 2003-05-27
Abstract: The new intraocular lens of the present invention is a one-piece composite lens having a soft, foldable central optic region and a hard, non-foldable outer peripheral region making up the haptics or legs of the intraocular lens. The soft, central optic portion of the lens is typically manufactured from a material capable of being folded so that the intraocular lens can be inserted through a small incision on the order of 3 to 4 mm. The hard haptic portion of the lens provides support for the lens in the eye after insertion and unfolding of the lens. The relatively rigid plastic lends support to the entire lens structure after its insertion into the posterior chamber of the eye, and tends to help stabilize the position of the lens after insertion and the closure of the incision. A preferred material of the soft optical region being a poly(hydroxyethyl methacrylate) or pHEMA or a copolymer thereof such as HEMA and 6-hydroxyhexyl methacrylate (HOHEXMA) or p(HEMA-co-HOHEXMA). The preferred material of the hard haptic region being made from a relatively hard plastic, such as (polymethyl methacrylate) or PMMA, or a copolymer thereof.

Title: Hydrocracking process involving colloidal catalyst formed in situ
Inventor: LOTT ROGER KAI
IPC: C10G47/26
Filed: 1993-01-29
Granted: 1997-07-08
Abstract: In a hydrocracking process a feed mixture comprising: heavy oil containing asphaltenes and sulfur moieties; an oil-soluble,  metal-containing  compound  additive  (such  as  iron pentacarbonyl or molybdenum 2-ethyl hexanoate), which additive is operative to impede coalescence of coke precursors and which forms hydrocracking catalytic particles in situ; and, optionally, a hydrocarbon diluent which is a solvent for asphaltenes and which will assist with dispersion of the additive; is mixed for a prolonged period at low temperature (e.g. 80°C - 190°C) in a first  vessel  or  vessels  to  disperse  the additive  without significantly decomposing the additive.  Preferably, the product mixture is then digested in a second vessel or vessels by mixing it at an elevated temperature (e.g.  250°C), to decompose the additive.  The resulting mixture is then heated to hydrocracking temperature  (e.g.  450°C)  and introduced into a reactor.   A hydrogen flow, sufficient to maintain mixing in the reactor and efficient (e.g. greater than 98%) stripping of light ends (e.g end point  boiling  220°C),  is  provided.    The  steps  of  low temperature  mixing  to  achieve  dispersion  without  additive decomposition, preferably digesting to decompose the additive under  mixing  conditions,  and  mixing  in  the  reactor  with stripping, combine to yield well dispersed, colloidal catalytic particles which function to impede coke evolution and provide high conversion of the high boiling (504°C+)  fraction of the feedstock.
