Inventor: OGAWA TAKATOSHI
IPC: C04B35/622
Filed: 1993-09-20
Abstract: A metal-oxide layer exhibiting a photocatalytic activity function is formed on the surface of an inorganic architectural material, such as external wall material, roofing material, internal wall material, flooring material, and ceiling material, including glass, tile, concrete, stone, metal, and the like, so as to provide the property of deodorizing a space coming in contact with the architectural material, and antimold, antisoiling properties, and ultraviolet-ray absorbency of the surface of the architectural material, as well as the long-term maintenance of these properties. Preferably, the metal-oxide layer is formed by fixing a metal-oxide thin film on the surface of the architectural material. Alternatively, the metal-oxide layer is formed as an architectural material in which the surface thereof and its vicinity are mainly formed of a metal mixture including a metal oxide, such as titanium oxide, and palladium for improving photocatalytic activity, or a metal mixture including a metal constituting the metal oxide, such as titanium, and a composite of a second metal, while its inner portion is substantially formed of a metal mixture including titanium or a composite of titanium and palladium, the surface and its vicinity as well as the inner portion being formed continuously. As a method of manufacturing the latter architectural material, a metal mixture, i.e., an alloy, of titanium and a metal for improving photocatalytic activity, such as palladium, is fabricated, and after the alloy is processed into a desired shape, the processed alloy is subjected to oxidation treatment.

IPC: B01D1/26
Filed: 1993-10-12
Abstract: A pulp mill has zero or minimum liquid discharges. The large amounts of liquid that must be processed to achieve this result are handled utilizing a multiple effect evaporator provided with heat from a steam exhaust of a condensing type steam turbine.  Super heated steam from the recovery and bark boilers is fed to the turbine to generate electricity for the production of bleaching chemical and other uses in the mill.  Three or four steam exhausts having different composite temperature and pressure values are taken from the turbine and used where most suitable in the pulp mill.  For evaporation of bleach plant effluent the steam taken from the turbine preferably has a pressure of about 1-3 psia and a temperature of about 120-140°F, and has no significant adverse affect on power generation.

Title: Chlorination process, alkylation of products of said process and some products thereof
Inventor: WALTERS MARLIN E
IPC: C07C13/567
Filed: 1992-10-20
Abstract: Compounds having acidic protons and a molecular structure which can delocalize the electron density of the conjugate base (target compounds) are chlorinated by contacting such compounds with a perchloroalkane and aqueous base in the presence of a phase transfer catalyst which is a tetraalkylammonium hydroxide. Chlorinated products, preferably gem-dichloro compounds, are produced. The gem-dichloro compounds are useful for alkylation of aromatic compounds. For instance fluorene is chlorinated to form 9,9-dichlorofluorene which is reacted with such compounds as phenol or aniline to form such compounds as 9,9-bis(hydroxyphenyl)fluorene, 9,9-bis(aminophenyl)fluorene, or 9-aminophenyl-9-chlorofluorene.

The present invention provides additional techniques for adjusting system parameters, such as dispersion-length products of first and second portions of the fiber span, in order to compensate for changes in first order dispersion resulting from non-zero second order dispersion. The method and apparatus also provide an improved multi-channel optical phase conjugation system design.
Patent CA-2131689-A1 (CA)
Inventor: BRADY DANIEL F
IPC: D06F33/37
Filed: 1992-10-26
Abstract: An apparatus and method for programming a detergent controller (12) to vary the detergent concentration set point (14) according to the time of day and to achieve detergent concentration levels quickly without incurring overshoot. Thus, the present invention insures that the warewashing machine is operated at optimum efficiency and cost. To vary the set-point according to the time of day, the invention combines the features of a microprocessor, a clock and a controller into one unit. The user enters the time setting (16) and set point into the controller (12). The microprocessor (10) then compares the real-time clock signal with the user time settings and outputs an appropriate set-point value from the microprocessor (10) to the controller (12). To achieve detergent concentration levels quickly without incurring overshoot, the controller (12) senses the detergent concentration and dispenses the proper detergent level to the warewashing machine according to a predetermined detergent feed time based on the previous response time and the programmed set-point (14). Thus, the controller (12) can change the response function if and when conditions change.

Abstract: SYSTEM AND METHOD FOR REMOTE MONITORING            ABSTRACT OF THE DISCLOSURE    A communication and processing system (10) for monitoring signals transmitted from personal transmitter units (PTUs 20) to determine whether alarm or emergency conditions have occurred and whether scheduled communications from PTUs (20) are missing.  The PTUs (20) detect various alarm and emergency conditions and transmit data communications to a field node (18).  The field node (18) receives data communications from all PTUs (20) within range.  If a data communication indicates an emergency condition, a field report message is immediately sent to a control facility (12).  If a communication indicates an alarm condition, an audible alarm is sounded at the field node but no message is sent to the control facility yet.  If the alarm condition is not corrected within a predetermined period of time, a message describing the alarm condition is sent to the control facility (12).  When scheduled communications from a PTU (20) are not received at the field node (18), the situation is treated as an alarm condition.

Title: Higher purity imidazoline based amphoacetate surfactants and processes for the preparation thereof
Inventor: DESAI BHARAT
IPC: C09K23/22
Filed: 1994-09-16
Abstract: ABSTRACT      Imadazoline-based amphoacetates of higher purity, containing essentially negligible amounts of unalkylated amido amines, lower amounts  of  glycolic  acid  salts  and monochloroacetate  salts, superior to currently available conventional amphoacetates, are provided.  This is demonstrated by their improved surface-active properties.  Lower inherent irritation properties may be expected due to improved purity.      The higher purity amphoacetates can be obtained via processes utilizing precise pH control during the reaction of imidazoline, or its open-chain derivatives, with alkylating agents, e.g. sodium monochloroacetate.  The pH can be controlled by adding the base slowly or automatically in response to a pH metering device to maintain a constant pH, or by a series of staged additions which are calculated to maintain pH within a stated range.  The reaction may also be carried out by conducting the initial hydrolysis of the imidazoline ring structure, followed by alkylation.  These higher-purity amphoacetates contain essentially fully alkylated products and lower amounts of glycolic acid derivatives, even though a ratio of SMCA to substituted imidazoline, or its open-ring derivative, of less than 1.5:1.0 and close to 1.0:1.0 is used.

Abstract: 2133431 9320638 PCTABS00164 Dans un poste de traitement de données, une interface-réseau (I; RE) surveille le canal de transmission et établit des signaux d'événements, comme "début d'une transmission", "détection de collision", et "retour du canal à l'état vide". En cas de collision sur émission locale, l'émission est maintenue avec signalement de collision pendant au moins une durée (C), puis interrompue. Un registre d'observation (RO) reçoit les signaux d'événement, et établit en réponse un signal d'observation du canal, qui peut être "transmission réussie", "tranche de collision", "tranche vide". Sur requête d'émission d'un nouveau paquet de données, il est effectué ou non (mode normal) une première tentative d'émission, en fonction de l'état du registre d'observation. En cas d'insuccès (refus d'émission ou collision), un mécanisme d'incrémentation/d'écrémentation d'un entier courant (E), convenablement initialisé, détermine le droit d'émettre, de sorte que la réaction à une requête d'émission d'un nouveau paquet de données est indépendante de l'historique du canal, en amont du dernier mode normal exécuté.
