Title: Process for preparing a polyester of hydroxy  naphthoic acid and hydroxy benzoic acid
Inventor: CHARBONNEAU LARRY F
IPC: C08G63/682
Filed: 1984-01-24
Granted: 1987-03-31
Abstract: ABSTRACT OF THE DISCLOSURE           Provided is a method for preparing aromatic copoly-esters of hydroxy naphthoic acid and hydroxy benzoic acid via an in situ esterfication technique whereby there is no isolation of the esterified monomers.  The process comprises reacting the aromatic hydroxy acid monomers with an agent such as acetic anhydride in order to esterify the hydroxy moieties and subse-quently polymerizing the esterified hydroxy monomers without isolation thereof, all in the presence of from about 5 to 50 ppm iron.  Advantageously, the process allows one to obtain a wholly aromatic polyester of high inherent viscosity and good melt stability while avoiding the time consuming step of having to isolate the esterified hydroxy monomers prior to polymerization.

Title: Apparatus for carrying out physical and/or chemical processes, more specifically a heat exchanger of the continuous type
Inventor: KLAREN DICK G
IPC: B01J8/24
Filed: 1984-07-16
Granted: 1988-02-09
Abstract: This invention relates to apparatus for carrying out physical and/or chemical processes, more specifically a heat exchanger (10) of the continuous type, comprising a large number of vertical heat exchanger tubes (18 mounted between a lower chamber (17) and an upper chamber (16) within a jacket (15). Within the tubes (18) small solid particles are kept in a fluidized condition by the fluid medium passing up from the lower chamber (17) through the tubes (18), so as to achieve a good heat transfer, whereas also any deposit will be removed from the inner tube walls. For the downward flow of the granular mass at least one return tube (21) is provided. Downward circulation of the fluid medium through the return tube (21) should be minimal, however, which can be achieved by an increase of the pressure difference between the upper and lower chamber (16; 17), which increase of the pressure difference can be achieved by fitting several distribution plates (24; 42) at a level above the return tube (21) outlet into the lower chamber (17), preferably so that the apertures in the various distribution plates (24; 42) of the multiple design are not vertically in line. The second distribution plate (42) also serves to minimise excessive wear of the material of the jacket (15) due to the eddying motion of the granules.

This radiation images the object on a detector plane.  In accordance with the invention there is provided a beam-splitting system, such that the fluorescent object is reproduced in the form of at least three, and preferably four separate and mutually adjacent images.  A selected filter is placed in each of the paths of these partial light beams.  The detector plane has a plurality of image-point detectors each of which produces a respective electric signal, so that there is obtained for each image point at least three, and preferably four intensity signals recorded for a respective frequency band determined by respective filters.  These signals are processed mathematically to provide a weighted signal value, which may be dimen-sionless.  These weighted image-point values are repro-duced, for example on a video-monitor, which makes possible fluorescence reproduction rich in contrast and free from disturbances with respect to spectral signa-tures.  One example of the use to which the invention can be put is the detection of cancer cells to which a fluo-rescence signature has been imparted with the aid of HPD.
