Patent CA-2143958-A1 (CA)
Title: Process for (co)polymerizing vinyl monomers
Inventor: FUKUMURA TAKUMI
IPC: C07C409/38
Filed: 1993-09-07
Abstract: The invention relates to a process for (co)polymerizing vinyl monomers in the presence of a radical polymerization initia-tor, characterized in that said radical polymerization initiator is a 3-methylpentyl-3-peroxy alkanoate of formula (1) wherein R1, R2 and R3 represent alkyl groups each having at most 9 carbon atoms with the proviso that the total number of carbon at-oms of R1, R2 and R3 is at most 11, said 3-methylpentyl-3-peroxy alkanoate being employed in an amount of 0.002 to 2.0 parts by weight, based on 100 parts by weight of monomers present, said process being carried out at a temperature above 20 °C. The use of 3-methylpentyl-3-peroxy alkanoates in the present invention surprisingly and unexpectedly results in a higher polymerization velocity, a shortened polymerization time, and an increase in conversion as compared with the results obtained by using other radical polymerization initiators. It has also been found that the obtained polymer has excellent thermal stability and is not affected by odour or coloration. Thus the industrial value of the radical polymerization initiator peroxide of the present invention is remarkably high.

Patent CA-2147188-A1 (CA)
Title: Method of controlling synchronization signal power in a communication system
Inventor: FUKASAWA ATSUSHI
IPC: H04B1/707
Filed: 1995-04-18
Abstract: To initiate communication, a first station generates a synchronization signal and sends it to a second station.          When the second station detects the synchronization signal, it acquires synchronization and sends a synchronization-acquisition message back to the first station.  The first station now reduces the power of the synchronization signal, but continues to send the synchronization signal, and also begins sending a modulated data signal.  The second station uses the synchronization signal to maintain synchronization for demodulating the data signal.

Title: Magnetomechanical article surveillance marker with a tunable resonant frequency
Inventor: LIAN MING-REN
IPC: G08B13/24
Filed: 1995-05-15
Abstract: A marker for use in a magnetomechanical electronic article surveillance (EAS) system is made by mounting a magnetostrictive element in a housing adjacent to a biasing element that is magnetized to a degree of magnetization that is less than saturation. The resonant frequency of the marker is detected. If the detected resonant frequency does not match a predetermined operating frequency of the EAS system, the degree of magnetization of the biasing element is adjusted so as to tune the resonant frequency of the marker to the predetermined operating frequency.

Inventor: EMMERSON DANA
IPC: B02C13/14
Filed: 1995-07-19
Abstract: Apparatus is provided herein for disposing of light bulbs, e.g., fluorescent bulbs. The apparatus includes an open-topped cylindrical container covered by a removable lid. A light bulb feed chute is attached to, and extends through the lid and has an inlet opening and an outlet opening disposed below the lower surface of the lid. An electric motor is mounted upon the upper surface of the lid and has a downwardly-extending rotatable shaft, projecting through the lid and terminating below the lower surface of the lid. An "on-off" electrical switch operates the electric motor. Inventive structure is provided for pulverizing a light bulb, e.g., a fluorescent tube, as it emerges from the outlet opening of the feed chute. That structure comprises a hub at the terminal end of the shaft. At least two equiangularly-disposed, multi-stranded, braided, wire cables are secured to the clamp. Each multi-stranded, braided, wire cable is provided with a terminal weight. When the shaft is rotating, each multi-stranded, braided, wire cable extends by centrifugal force across the outlet opening of the chute into the path of the bulb. The cables pulverize the bulb by the combined breaking and abrasive action of the multi-stranded, braided, wire cable.

Patent CA-2159386-A1 (CA)
Inventor: LOGAN SHAWN MICHAEL
IPC: H03B1/00
Filed: 1995-09-28
Abstract: Oscillation is easily and reliably initiated in an oscillator by increasing the gain of the circuit at startup time. For example, the gain of an oscillator circuit may be increased at startup by reducing the value of a user controlled impedance until oscillation commences. Alternatively, or in combination, the input impedance of an amplifier used in the oscillator may be reduced at startup to facilitate the initiation of oscillation.

Patent CA-2160197-A1 (CA)
Title: Caulking gun for variant viscosity media
Inventor: PENG YUENAN
IPC: B05C17/01
Filed: 1995-10-10
Abstract: A caulking gun having a fixed first bearing surface, and an engagement member for preventing rearward movement of a plunger shaft while permitting forward movement thereof. Following termination of forward movement of the plunger shaft in response to operation of a handle mechanism of the gun, the plunger shaft selectively can be moved rearwardly a predetermined distance in response to cartridge back pressure. In an alternative mode of operation, the rearward movement is substantially prevented for effecting precise control and smoothly continuous feeding of media from the gun. In one configuration, a shifting link permits movement of the plunger shaft together with the engagement member up to a distance E when a control surface is positioned for providing forward movement of the engagement member in response to forward movement of the plunger shaft. In another configuration wherein the handle mechanism has ratcheting engagement with the plunger shaft, a counterpart of the engagement member is pivotable relative to opposite ends of a fixed pivot slot in response to positioning of the control surface.

Title: Liposomal defensins
Inventor: JANOFF ANDREW S
IPC: A61P31/04
Filed: 1994-10-25
Abstract: Defensis are microbicidal, numoricidal cytotoxic protein componements of animal host defense systems. They can be entrapped in liposomes containing release-inhibiting lipid such that the defensins are neutralized, and their release from the liposomes is inhibited; however, the defensins remain effective when exposed to endocytosed material in endocytic vesicles. Liposomal defensin formulations are administered to animals for the treatment or prevention of microbial infections, for the treatment of cancers and for the treatment of disorders characterized by a deficiency of protein-mediated cytotoxic activity in cytiolasmic granules.

Title: Synthesizing and screening molecular diversity
Inventor: SUGARMAN JEFFREY H
IPC: C12Q1/68
Filed: 1994-11-02
Abstract: A device and method for efficiently synthesizing diverse molecular products on substrates. A parent vessel (200) contains a suspension of substrates. The suspension is pressurized with argon and transferred to a plurality of reaction vessels (201-209) in one or more reaction vessel banks where monomer addition reactions take place. Optionally, the substrates may be tagged with a tag monomer. A vortexing motor (300) vortexes the contents of reaction vessels (201-209) during monomer addition reactions to enhance synthesis. After the desired monomer and/or tag monomer addition reaction, the suspension is pressurized with argon and transferred back to parent vessel (200) for mixing. Thereafter, the suspension may be pressurized with argon and reallocated among reaction vessels (201-209) for further synthesis.

Title: Magnetic door seal for infant incubator
Inventor: SIMENAUER ROBERT M
IPC: A61G11/00
Filed: 1996-05-07
Abstract: An infant incubator having a base and a hood positioned atop of the base to form an infant compartment therebetween. The hood has a front access door that is hinged so as to move between an open and a closed position. The edge of the door opposite the hinged part has a magnetic strip that mates with a strip of magnetically attractable material positioned on the edge of the hood opening such that the door is retained in its closed position by a magnetic force. At least one door handle is mounted to the door at or near the end of the magnetic strip at the top of the door and can be pulled to open the door. The door is sufficiently flexible that pulling the handle causes a peeling effect such that relatively little force need be exerted to open the door from the corner, yet considerable force is required to open the door from inside the incubator by an infant residing therein.
