Patent BE-906007-A (BE)
IPC: D21H21/10
Filed: 1986-12-22
Abstract: Aqueous suspensions of papermaking fibres and filler are each separately treated with an anionic or a cationic polymer, after which the filler (preferably) or the papermaking fibre is treated with a polymer of opposite charge to that used in the initial treatment. The filler and papermaking suspensions are then mixed to form a papermaking stock, with dilution as necessary before, during or after the mixing operation. This stock is then used to form a loaded paper web in conventional manner. The initial treating polymer is preferably a papermaking retention aid or flocculant, e.g. a cationic polyacrylamide or an amine/amide/epichlorohydrin copolymer in the case of cationic materials or an anionic polyacrylamide in the case of anionic materials. The further treating polymer is preferably an anionic or cationic starch, depending on the charge of the initial treating polymer.

Abstract: Abstract A temperature sensitive switching circuit includes a current source supplying two groups of serially connected diodes.  The number of such diodes in the first group is smaller than that in the second so that the first group draws substantially all of the source current and the second only an infinitesimal portion of this current.  As temperature increases, the voltage across both groups of diodes decrease, but the ability of the second group to carry a substantial amount of current increases at a more rapid rate than this decreased voltage would tend to reduce such current, and increases non-linearly with temperature above a given threshold temperature.  This non-linear increase in current flow may be used to sense temperature change and also to control the power responsible, either directly or indirectly, for this temperature change.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a method for manufacturing a heat exchanger and to the heat exchanger manufactured by the method, especially, a type of a heat exchanger which has a plurality of pipes and end plates as the components for heat exchanging therein.  For manufacturing of the type being of the heat exchanger with pipes and end plates, it is necessary to compose them so as to form paths  for fluids between which heat is exchanged and so as to seal completely the paths.          This invention enables to manufacture successfully such type of the heat exchanger in comparison with the conventional methods which need welding or brazing of the pipes with end plates to seal the  paths.  A compact heat exchanger with complete sealings is obtained by the invention and it is free from troublesome and laboring works of welding or brazing.

Abstract: ABSTRACT      Hot reducing gas (e.g. at 1000 to 1100°C) suitable for use in reducing oxidic ores is produced by reforming and partially oxidizing a fluid hydrocarbonaceous fuel (e.g. fuel oil) with a gaseous oxidant (e.g. oxygen or H20) in a plasma medium at approximately 2000°C, to form a high temperature gas comprising a major pro-portion of C0 and H2 and a minor proportion of C02 and H20, and then adding a hydrocarbonaceous gas (e.g.          CH4) to the high temperature gas so that further reforming reactions occur which reduce the proportion of C02 and H20.

Abstract: ABSTRACT OF THE DISCLOSURE         A lighting control apparatus (dimmer) responsive to an electrical demand signal to control the portion of the voltage cycle during which voltage is supplied to one or more discharge lamps from AC voltage source, using a pulse enable circuit to provide pulsing of the firing circuit appropriate for discharge lamps.  The apparatus comprises a shaping cir-cuit responsive to a demand signal, a timing circuit, a pulse enable circuit, a single pulse per half-cycle firing means, and a solid state switching means.  The pulse enable circuit prevents activation of the firing means when the solid state switching means is in a conductive state (firing pulses based on the voltage cycle could otherwise occur before the lagging current of the previous halt has fallen to zero).  This combines the advantages of low power consumption of single pulse firing circuits with a reliability of firing of discharge lamps obtained heretofore only in multiple pulse firing circuits.

Abstract: FUEL CELL COOLING SYSTEM WITH   SHUNT CURRENT PROTECTION     ABSTRACT OF THE DISCLOSURE     A fuel cell coolant system for use with a plurality of fuel cell stacks connected electrically in series is adapted to use a non-dielectric coolant carried through each stack by electrically conductive tubes.  Each stack also includes a plenum for distributing coolant to the tubes.  To prevent short circuits across the stacks due to shunt currents in the coolant the plenums are electrically insulated from a grounded main coolant supply line, such as by dielectric hose connections, and each plenum is electrically connected to one end of its respective stack.  By this invention the maximum driving potential for any shunt current is the potential drop across a stack rather than the potential drop from a stack to ground.  In a preferred embodiment dielectric hoses are used to connect the plenums to the tubes in order to prevent short circuiting across cells within a stack.

Abstract: ABSTRACT OF THE DISCLOSURE:           A cement mixture is mixed or agitated in a hopper by rotary blades and is fed through a feed duct or chute normally imparted with vibrations from a vibrator to cement mixture receiving pockets in a rotary disk.  The cement mixture in the pocket brought to an unloading position is forced to be discharged through a discharge pipe under the force of the air under pressure admitted into the pocket through a blow pipe.  Since the feed duct or chute is normally vibrated, even a highly viscous cement mixture containing water can be fed through the feed duct or chute into the pockets of the rotary disk in a stable manner so that the cement mixture may be prevented from bridging across the pockets of the rotary disk, thereby not dropping into them.
