Patent CA-2017353-A1 (CA)
Inventor: BUONERBA CLAUDIO
IPC: C08F2/02
Filed: 1990-05-23
Abstract: Described is a process for the continuous bulk production of high impact vinylaromatic copolymers in which a vinylaromatic monomer, an optional vinyl-cyanide comonomer, a rubber, a part of a diluent solvent and a catalyst are premixed at a temperature below 100 DEG C and fed to an agitated tubular plug-flow reactor which is divided into several stages or zones. The excess mixture is recycled to the premixer and the remaining portion of the diluent solvent is injected in the top of the reactor to prevent the formation of incrustations. In the first zone of the reactor, the temperature and the residence time of the mixture are controlled so as to halve the catalyst lifetime. The polymerization is continued in the subsequent zones of the reactor until at least 40% by weight of solids have been formed.

Title: High-precision adjustable injection molding of single-mode fiber optic connectors
Inventor: BRIGGS PAUL R JR
IPC: G02B6/38
Filed: 1990-07-30
Abstract: Abstract of the Invention An injection-molded connector for single-mode optical fibers includes two mating plugs having aligned fiber-receiving holes. To keep transmission losses in the connector at an acceptable level, the eccentricity of each hole relative to its-plug profile must be maintained within a fraction of a micron. In accordance with the invention, the mold utilized to form the plugs includes a dual-eccentric-cam adjustment mechanism that comprises nested conically shaped cams Rotation of the cams serves to move a part of the mold that positions a hole-forming pin. By means of this mechanism, the eccentricity of the fiber hole relative to the profile of the molded plug can be established and maintained within the required precision.

Title: Addition of radical initiators to resid conversion processes
Inventor: WIEHE IRWIN A
IPC: C10G9/00
Filed: 1990-09-17
Abstract: ABSTRACT OF THE DISCLOSURE           The present invention  is predicated on  the discovery that the  addition of  certain free  radical initiators to thermal conversion processes results  in increased thermal conversion rate at a given  tempera-ture without any substantial  increase in the  amounts of gaseous  products formed.   This permits  operating the thermal conversion  process at lower  temperatures than otherwise practical.  Indeed, the present  inven-tion is especially useful in thermal cracking process-es like  fluid coking.   In  this embodiment,  a  free radical initiator is added, without the addition of  a hydrogen  donor  diluent,  to  a  feedstock  which  is thermally cracked in  a fluidized  bed of  particulate solids  and  at  lower  temperatures  than   otherwise employed, whereby increased amounts of liquid products are obtained.
Patent CA-2027374-A1 (CA)
Title: Electrochemical degradation of chlorophenols
Inventor: KUDO AKIRA
IPC: C25B3/23
Filed: 1990-10-15
Abstract: Abstract A method is described for the electrochemical degradation of chlorophenols.  The chlorinated phenols are adsorbed onto an activated carbon, e.g. graphite felt, electrode and are simultaneously subjected to electrochemical mediated oxidation in the presence of chloride ions and/or radicals.  This results in the destruction of the halogenated compounds and the simultaneous rejuvenation of the electrode surface. Powerful oxidizing agents are generated at the anode and these are capable of decomposing chlorinated phenols into CO2 and other dechlorinated organic components.

Title: Hydrocracking of asphaltene-rich heavy oil
Inventor: LEWKOWICZ LESZEK
IPC: C10G47/02
Filed: 1990-11-28
Abstract: An  oil-soluble   molybdenum   compound   (preferably molybdenum naphthenate)  is mixed with a heavy oil fraction containing asphaltenes and sulfur.   Mixing is conducted at an elevated temperature (150-300°C), whereby the Mo is dispersed and preferentially becomes associated with the asphaltenes  in a colloidal  form.    The  product  is  then  further  heated  to hydrocracking temperature.   Hydrocracking  is  conducted with sufficient hydrogen flow to ensure a hydrogen flow/liquid flow ratio greater than 10, a liquid Peclet No. less than 0.5 and a gas Peclet No. greater than 3Ø  At these conditions the liquid is mixed in the reactor and light ends are stripped as they are produced.   It is found that asphaltene conversion is high and solid coke formation is low when the process is practiced.

Title: Suction box apparatus with composite cover elements mounted in slots on cross braces
Inventor: SIMMONS HOLT W
IPC: D21F1/52
Filed: 1991-02-18
Abstract: Dewatering apparatus for papermaking machines, such as suction boxes, are provided with spaced cover elements of a composite structure. The cover elements include ceramic cover strips which engage the porous conveyor belt that conveys the paper web and are separated by drainage slots. The ceramic cover strips are bonded to support members of fiber-reinforced plastic. The cover elements are mounted on metal cross braces by mounting projections on the support members which slide into mounting slots of the same shape on the cross braces for attachment thereto without threaded fasteners or welding.      The mounting slots and mounting projections may be of an interlocking shape, such as a dovetail shape or a T-shape, which prevents vertical movement of the cover elements toward or away from the conveyor belt while allowing horizontal sliding movement for insertion and removal of the cover elements into the mounting slots of the cross braces.
