Patent CA-2061697-A1 (CA)
Inventor: MINAMI YOICHIRO
IPC: H04J3/06
Filed: 1992-02-24
Abstract: After bit synchronization and frame synchronization are established in accordance with a transmission signal from a transmission office, reception RX is stopped until a reception timing assigned to a group of a portable radio unit comes.  A receiving operation is performed again at the reception timing assigned to the group of the unit.  If the ID code of the received signal coincides with the ID of the unit, an informing operation is performed.  At the same time, transmission TX is performed.  A transmitting operation is performed during a transmission signal stop period TXOF upon completion of transmission of data corresponding to all the eight groups.  The transmission timing of the portable radio unit is based on the fact that frame synchronization is established in the reception RX, so that transmission TX is performed at a timing assigned to the group of the unit in the reception RX.  The above-described timings prevent the transmission office and the portable radio unit from performing simultaneous transmission.

Title: Sizing agent for paper
Inventor: TAKAHASHI YOSHIO
IPC: D21H17/00
Filed: 1992-05-12
Abstract: ABSTRACT OF THE DISCLOSURE       The present invention relates to a sizing agent which exerts excellent sizing efficiency even under severe conditions, namely, at an elevated temperature in the paper-making step, or at high conditions with a limited aluminum sulfate addition.        The sizing agent for paper of the present invention is derived from i) dehydration condensation of an alkenylsuccinic anhydride and an organic carboxylic acid with a polyalkylene polyamine and ii) saponification of the remaining carboxyl groups with alkali following the dehydration condensation.  More particularly, the present invention relates to a water-soluble sizing agent which is obtained by mixing an alkenylsuccinic anhydride with 1 to 20 times by molar equivalent, based on said alkenylsuccinic anhydride, as much as an organic carboxylic acid, adding 0.1 to 2.0 times by molar equivalent, based on said alkenylsuccinic anhydride, as much as a polyalkylene polyamine thereto so as to perform dehydration condensation. An then, to make the reacted material soluble to water, the remaining carboxyl groups are saponified with an alkali in an amount almost corresponding to the saponification equivalent.

Title: Security bags and sealing means
Inventor: DIXON DARRYL O
IPC: B65D33/34
Filed: 1992-05-21
Abstract: ABSTRACT               SECURITY BAGS AND SEALING MEANS          The invention relates to a security bag intended for carrying money or confidential documents and which if opened and resealed provides an indication that the bag has been tampered with.  The bag has an opening means and sealing means comprising a transparent flap adapted to fold over the opening to seal the bag by adhering the bag to an area of the bag adjacent the opening.  The sealing means is formed of a material whose surface has a lower co-efficient of friction or is otherwise less retentive of print than the area.  The sealing means is printed or otherwise marked with a pattern such that when the sealing means is adhered to the area to seal the opening a mirror image of the pattern is transferred to the area while remaining on the sealing means.  The sealing means is of a thin easily distorted material making it extremely difficult to match the original pattern once the bag has been opened and if an attempt is made to re-seal it.
Patent CA-2069960-A1 (CA)
Title: Bispecific heteroantibodies with dual effector functions
Inventor: FANGER MICHAEL W
IPC: A61K35/14
Filed: 1990-10-18
Abstract: Bispecific molecules which react both with the high-affinity Fc.gamma. receptor of human effector cells and with a target cell surface antigen are disclosed. Binding of the molecules to the Fc receptors found on effector cells is not blocked by human immunoglobulin G. The molecules are useful for targeting human effector cells (e. g. macrophages) against cells bearing the target antigen. For this purpose, bispecific molecules can be constructed containing the binding region derived from an anti-Fc.gamma. receptor antibody and the binding region derived from an antibody specific for the target antigen. Targeted effector cells can be used to destroy cells bearing the target cell surface antigen by cell-mediated antibody dependent cytolysis and by complement-fixation.

Abstract: ABSTRACT OF THE INVENTION      A process and system for treating aluminum salt cake containing water soluble halide salts by contacting the salt cake with water to dissolve water soluble halide salts forming a saturated brine solution.  Transporting a portion of about 25% of the saturated brine solution to a reactor and introducing into the saturated brine solution at least an equal volume of a water-miscible low-boiling organic material such as acetone to precipitate a portion of the dissolved halide salts forming a three-phase mixture of an aqueous-organic-salt solution phase and a precipitated salt phase and an organic rich phase.  The precipitated salt phase is separated from the other phases and the organic rich phase is recycled to the reactor.  The remainder of the saturated brine solution is sent to a multiple effect evaporator having a plurality of stages with the last stage thereof producing low grade steam which is used to boil off the organic portion of the solution which is recycled.
