Title: A process for the preparation of rubber-reinforced monovinylidene aroma tic polymers
Inventor: AERTS LUDO M
IPC: C08F285/00
Filed: 1990-08-08
Abstract: Disclosed is an apparatus and process for the continuous production of a rubber-reinforced polymer composition having a bimodal particle size distribution using parallel, substantially plug flow reactors to separately polymerize the same or different solutions of a rubber in a monovinylidene aromatic monomer and optionally at least one other comonomer. After separate partial polymerizations to conversions of from 10 to 50 percent based on the total monomers present, first and second prepolymer compositions are produced containing rubber particles having average particle sizes of from 0.05 to 1.5 micrometer and from 0.7 to 10 micrometer, respectively, with the average rubber particle size of the second prepolymer composition being at least 1.3 times the average rubber particle size of the first prepolymer composition. The first and second prepolymer compositions are continuously removed from their respective reactors and mixed in a proportion such that the rubber particles derived from the first prepolymer will constitute from 50 to 95 percent by weight of the rubber content of final product after further polymerization and recovery of the resulting polymer product from any unreacted starting materials. This invention is advantageously used to prepare HIPS-type products with small particles in the range from 0.2 to 0.7 micrometer and larger particles in the range from 1.5 to 5 micrometer or ABS-type products with small particles in the range from 0.5 to 0.8 micrometer and large particles in the range from 1 to 3 micrometer.

Patent CA-2030136-A1 (CA)
Inventor: MANSSEN KEITH R
IPC: H05K3/34
Filed: 1990-11-16
Abstract: A ceramic block filter (100) includes coupling pins (101 and 102) disposed in holes (124 and 125) in corresponding electrodes (121 and 122) for interconnecting the filter to radio frequency devices, such as a radio transceiver. During manufacture of the filter (100), the coupling pins (101 and 102) are bonded to conductive material (131) of the holes (124 and 125) and corresponding electrodes (121 and 122) when the rest of the conductive material (160) is fired. To facilitate the electrical bond during the manufacturing process, the coupling pins (101 and 102) may be silver or silver plated and co-fired at the same time. Since the coupling pins (101 and 102) are fired at the same time as the rest of the conductive material, a reliable and inexpensive bond is achieved between the coupling pins (101 and 102) and the conductive material of the holes (124 and 125) and corresponding electrodes (121 and 122).

Title: Froth flotation apparatus and method
Inventor: CRUEA RONALD D
IPC: D21F1/70
Filed: 1990-11-21
Abstract: Abstract Apparatus for separating contaminant particles from liquid suspension stock, e.g. in the de-inking of used news print, is characterized by one or more of a plurality of features which contribute to increasing the capacity and effectiveness of the apparatus, including the provision of a cell comprising inner and outer annular chambers of substantially equal depth with the inlet and outlet connections for the stock being located adjacent the bottoms of the two chambers to force the stock to travel through the full depth of each chamber, and also the provision of a baffle of substantial width on the top of the wall between the two chambers to spread the stock overflowing that wall into a thin film.  Other features include the use of an explosion-type flowbox to aerate the stock as it is delivered to froth flotation apparatus, and an alternative aerating device comprising a drum-shaped rotor having an irregular outer surface which is positioned in the stock inlet conduit leading to the cell on an axis extending transversely of the conduit, a nozzle positioned to direct a supply of air against the rotor surface on the upstream side of its rotational axis, and a drive causing the rotor to rotate at a linear speed of its outer surface which is substantially higher than the linear flow rate of the stock in the conduit so that the rotor surface breaks up the air impinging thereon into bubbles and distributes those bubbles in the stock flowing therepast to create foam within the cell.

Title: Mobile facsimile telecommunications system capable of automatically off-hooking a facsimile device
Inventor: TAKAHASHI CHUSEI
IPC: H04N1/327
Filed: 1991-01-30
Abstract: A mobile facsimile telecommunications system utilizes an automobile telephone system as a transmission path. In one aspect, this system utilizes an adaptor which can place the facsimile device under an off-hook condition without using an ordinary telephone set additionarily provided to compensate for defects of a portable-type facsimile device having no dialing function, thereby achieving its simplification of system construction as well as the reduction of telephone charges. In another aspect, this system utilizes an automatic response function, a polling transmission function using a given default value, and an automatic off-hook function specified by an operator after conversation, thereby rendering the manipulation for facsimile communication simple.

Title: Exhaust gas catalyst monitoring
Inventor: BRADSHAW BENJAMIN J
IPC: F01N11/00
Filed: 1991-02-12
Abstract: ABSTRACT .          EXHAUST GAS CATALYST MONITORING.        Operation of an internal combustion engine is controlled by an engine management system in response to a lambda sensor which monitors the oxygen content of exhaust gas flowing into a catalytic converter.  A universal exhaust gas oxygen (UEGO) sensor monitors the amount of oxygen in exhaust gas leaving the converter.  The engine management system  cycles the air/fuel ratio above and below stoichiometric and the peak-to-peak amplitude of the UEGO sensor output represents the performance of the catalyst in the converter such that larger amplitudes correspond to poorer performance.

Title: Reverse sample genome probing of sulphate-reducing bacteria
Inventor: VOORDOUW GERRIT
IPC: C12Q1/68
Filed: 1991-05-10
Abstract: A reverse genome probe process for detecting the presence of sulfate-reducing bacteria consists of: (a) obtaining an individual culture of at least one "selected standard" (which selected standard may be either a single sulfate-reducing bacterium or a group of more than one sulfate-reducing bacteria having homologous, cross-hybridizing genomes); (b) affixing a nucleic acid preparation from each selected standard to a solid surface; (c) preparing a "reverse" probe by labeling a nucleic acid preparation obtained from a sample taken from an oil field environment; (d) contacting the reverse probe with the solid surface under conditions which permit hybridization; and (e) detecting the presence of any reverse genome probe.      By using the "reverse" probe (i.e. a probe prepared from the sample, as opposed to a probe prepared from a selected microorganism), a single incubation may be used for the initial characterization of an unknown sample.
