Patent CA-2267469-A1 (CA)
Title: A method in supplying combustion air to a combustion chamber, arrangements in said combustion chamber as well as use of oxygen-containing exhaust from a gas turbine
Inventor: SOLAND ARNE
IPC: F02C6/18
Filed: 1997-10-07
Abstract: A reformer (24) which may be included in a process plant, comprises a reactor chamber (28) having a combustion chamber (26), to which fuel and combustion air are supplied. The exhaust gas from the combustion chamber (26) may have a very high temperature, e.g. 650 °C. The combustion chamber (26) supplies heat energy to the reactor chamber (28) in which a heat treatment of gas can take place. The process plant comprises at least one gas turbine (10). In order to reduce the consumption of energy, the exhaust gas discharge outlet (at 20) of the gas turbine (10) is through a channel (22), directly or indirectly, in fluid communication with the combustion air inlet of said combustion chamber (26), so that turbine exhaust gas preheated to a substantial temperature, e.g. 350 - 450 °C, is blown through said channel, etc., (22) through the overpressure of the turbing exhaust gas, e.g. of up to 0.5 bars, without the need for a fan, to the intake of the combustion chamber (26).

Title: Processes for preparing calcium carbonate
Inventor: OKAMOTO YASUHIRO
IPC: D21H19/38
Filed: 1997-12-09
Abstract: Inexpensive spindle- or rice-like calcium carbonate giving useful properties for brightness, opacity and wire abrasion resistance as a paper filler is provided by taking advantage of the causticization step. When a white liquor is used for slaking a quick lime, the quick lime used in the slaking reaction of a first step has a calcium carbonate content of 10% by weight or less and is slaked with the white liquor at a concentration of 20 to 60% to prepare a milk of lime. When a green liquor is used for slaking a quick lime, the quick lime used in the slaking reaction of a first step has a calcium carbonate content of 0.1 to 10% by weight and is slaked with the green liquor at a concentration of 20 to 60% to prepare a milk of lime. In a second step, causticization reaction takes place at a green liquor loading rate of 0.02 to 0.5 cc (green liquor) /min/g (quick lime) at a reaction temperature of 20 to 105°C to afford spindle- or rice-like calcium carbonate.
Patent CA-2276343-A1 (CA)
Inventor: KAISER BERNHARD
IPC: H04Q3/545
Filed: 1999-06-25
Abstract: The invention comprises a procedure for providing a telecommunication service in a telecommunication network (T_NET), a service provisioning system (SDS) and a service switching point (SSP1 to SSP3) for implementing the procedure. The service provisioning system (SDS) is equipped with a global service control point (GSCP1, GSCP2) for performing the service control functions and several service switching points (SSP1 to SSP3). These perform service switching functions which, through the service request messages from subscribers (A) of the telecommunication network (T_NET), are induced to send service request messages to service control functions, which in turn control the implementation of the respective telecommunication service. The service provisioning system is also equipped with one or several local service control points (LSCP1 to LSCP4) for the implementation of service control functions, whereby each of the local service control points (LSCP1 to LSCP4) is assigned to one of the service switching points (SSP1 to SSP3) and is connected to this switching point via a local communication mechanism (L_NET1 to L NET3).      Depending on the telecommunication service being controlled by the service control function, the service control function that is assigned to a service switching function is installed globally in one of the global service control points or locally in one of the local service control points. For each service request message, the service switching point (SSP1 to SSP3) establishes whether the assigned service control function is currently installed locally or globally, and transfers the service request message accordingly.

Abstract: N-alkylpideridine dervatives represented by general formula (1) or (2);  reagents containing the same for assaying central local AchE activity; a method of assaying the central local AchE activity; and labeled precursors of the above compounds, wherein R1 represents optinally fluorinated lower alkyl;  R2 represents lower alkyl; and R3 represents alkenyl substituted at the 1-position by hydroxy, lower alkoxy, lower alkoxyalkyloxy, lower alkoxyalkyl-oxyalkyloxy or lower alkanoyloxy and at the end by radioactive iodine, or alkenyloxymethyl substituted at the end by radioactive iodine. After easily passing through the cerabral blood barrier, these compounds are hydrolyzed specifically by AchE in the brain into alcohols and then captured by the brain. The alcohols formed in the brain do not migrate into the brain. At the same time, they emit .gamma.-ray at an appropriate energy level. These characteristics make the compounds highly useful as tracers for SPECT in assaying the central AchE activity.
