Patent CA-2073140-A1 (CA)
Inventor: ISHIBASHI RYOICHI
IPC: G06F13/00
Filed: 1992-07-03
Abstract: In a B-ISDN network including a number of subscriber systems, there is a requirement for controlling access competition among the various terminals of each subscriber system under the DQDB protocol.  In a subscriber system, the terminals are electrically connected to a dual bus comprising a downbus and an upbus both extending from a network terminal.  Each of the terminals has a data transmission processing unit, a downbus processing unit, an upbus processing unit, a timer and a failure detecting unit.  When a data transmission request is issued from the data transmission processing unit, the failure detecting unit is activated in response to this request to start the timer so as to count a given time interval.  If either a request message or data cannot be sent before the timer times out, then the failure detecting unit determines that a failure has occurred in the dual bus.

Title: Catalyst and process for removal of sulphur compounds and oxides from fluid streams
Inventor: MAHADEV KALABAEERAPPA N
IPC: C01B21/24
Filed: 1991-05-13
Abstract: 2087265 9220621 PCTABS00017 The invention comprises a regeneratable catalyst that is capable of providing a reactive oxygen to partially oxidize sulphur-containing compounds to produce sulphur. It includes a method for removing sulphur compounds including both sulphur oxides and hydrogen sulphide from a fluid stream and decomposing such compounds to produce sulphur. Sour natural gas can be sweetened effectively by this invention, and sulphur can be prepared thereby. The catalyst is preferably formed by impregnating alkali metal sulfide and sulfide(s) or selenide(s) of metal(s) showing polyvalent and/or amphoteric character, e.g. Zn, etc. on a microporous type support (e.g., alumina). Its activity is sustained by exposure to a source of oxygen, such as air, oxygen sulphur dioxide or nitrogen peroxide and the like. A method is also described by which sulphur dioxide may be absorbed from flue gas and converted to sulphur, while higher oxides of nitrogen and carbon dioxide are being absorbed for subsequent recovery, utilizing a catalyst that has been conditioned by prior exposure to a reducing gas.

Title: Granular materials having an improved ceramic coating and composite sheets including same
Inventor: GEORGE BILLY L
IPC: C09D5/16
Filed: 1993-02-04
Abstract: A granular material which includes an inorganic substrate and a ceramic coating shows improved adhesion to bituminous surfaces, decreased alkalinity, and, when formulated as a three coated algae-resistant granule, exhibits improved algae-resistance over previously known granules. The ceramic coating comprises the reaction product of an alkali metal silicate and an aluminosilicate, the ceramic coating further including a borate compound and zinc oxide having a particle size less than 0.13 micrometer. It has been found that the use of a borate compound and zinc oxide having the stated particle size allows the granules to be adhered to a substrate for longer periods of time, thus producing a surface which retains its original color for a longer period of time. Methods of producing such ceramic-coated granular materials, and composite sheets including the granules are also presented.

Title: Method of producing cement clinker
Inventor: KUPPER DETLEV
IPC: C04B7/44
Filed: 1993-05-25
Abstract: Abstract The invention relates to a method of producing cement clinker from fine-grained cement raw material which after preheating and calcining is burnt in a clinker burning zone divided into two stages and is then cooled.  Optimum process conditions, particularly in the clinker burning zone, are achieved in that the calcined material is first of all heated to a temperature up to the region of the sintering temperature in a state formed by a fluldised bed or spouted bed so that a build-up granulation of the material is brought about, whereupon the material thus heated is heated to the sintering temperature in a second stage of the clinker burning zone which acts as the finish-burning stage and tempered to the finishing burn.

Abstract: Hybrid polymers of epoxy resins are provided by polymerizing ethylenically unsaturated monomer in the presence of epoxy resin using a combination of oil soluble and water soluble surfactants in separate organic and aqueous phases, respectively, made up prior to combining under polymerizing conditions. The organic phase contains the monomer and epoxy resin and oil soluble surfactant while the aqueous phase contains water and the water soluble surfactant. Initiator systems can be included in the organic phase or added independently to the reaction mixture. The resulting hybrid epoxy polymer exhibits excellent properties when applied as a protective film or adhesive, and aqueous dispersions of the polymer can be compounded with polyfunctional amine curatives and still remain stable for long periods of time, making a convenient one-pack system that can be cured on application, drying and heating at a relatively low temperature.
