Patent CA-1276686-C (CA)
Title: Portable intrusion detection warning system
Inventor: HALL W LAWRENCE
IPC: G08B25/10
Filed: 1987-11-19
Granted: 1990-11-20
Abstract: PORTABLE INTRUSION DETECTION WARNING SYSTEM Abstract A portable intrusion detection, monitoring and alarm system is housed in a portable carrying case in the configuration of a briefcase with handle for convenient portability and inconspicuous placement at a desired location near a space to be monitored.  Intrusion detectors are removed from the carrying case and placed in the space to be monitored.  The intrusion detectors may include infrared motion sensors and radio transmitters for transmitting detection signals to a radio receiver in the carrying case.  An electronic controller receives the detection signals from the radio receiver and delivers actuating data signals to a digital communicator and digital dialer with a telephone line output.  The digital communicator captures a telephone line with dialing signals and sends further coded signals corresponding to different monitored spaces and intrusion detectors from which detection signals are received.  The electronic controller includes an arming circuit and key switch for arming and disarming the monitoring and warning system.  The external power supply plug, telephone jack. and key switch are mounted on the carrying case so that the components are operable from outside the carrying case with the intrusion detectors in place and the briefcase configuration carrying case closed and locked.  Internal battery standby power supply is also provided.

Title: Non destructive testing for creep damage of a ferromagnetic workpiece
Inventor: METALA MICHAEL J
IPC: G01N3/00
Filed: 1987-12-18
Granted: 1991-01-02
Abstract: Abstract of the Disclosure Rapid  nondestructive testing of  a  ferromagnetic workpiece for creep damage is carried out by placing an eddy current  coil  adjacent  to  the  workpiece,  passing  an alternating current through  the coil,  measuring the eddy current  response  as  influenced  by  the  workpiece,  and comparing the current measurement to a current calibrated to known creep damage  for  the given  ferromagnetic material.          Correlations of the eddy current response to creep rate and time  to  failure  are  generated  from  creep  rupture  tests performed on specimens of the given material subjected to varying  conditions  of  time,   temperature  and  stress.       Qualitative  tests  can  also be performed to  identify the point of greatest creep damage by passing the eddy current coil over the workpiece to find the location of the lowest eddy current response.  Conventional creep damage tests can then be performed at that location if desired.

Title: Process for removal of basic materials from plant products using solvent extraction
Inventor: GRUBBS HARVEY J
IPC: C11B9/02
Filed: 1987-12-23
Granted: 1993-05-18
Abstract: PROCESS FOR REMOVAL OF BASIC MATERIALS            Abstract of the Disclosure A process is provided for the selective removal of basic materials from plant products, in particular, for removing nicotine from tobacco with out materially affecting the content of the other components of the tobacco.  Tobacco is traversed with a solvent in the supercritical state or in the liquid state wherein nicotine and the other components dissolve in the solvent.  The solvent is then passed through an acid-containing trap where the solvent is essentially freed of nicotine.  The solvent, depleted of nicotine and enriched in the other components, is then recycled to the tobacco to reextract nicotine. In addition, the tobacco may be pretreated with a chemical base which does not substantially react with the tobacco components under ambient conditions but rather is activated under the conditions of the extraction process.  Pretreatment of the tobacco with a chemical base neutralizes nicotine salts and permits the extraction process to be carried out under milder conditions.

Abstract: A method is provided for obtaining a vaccine against the different pathogenic serotypes of group B Neisseria meningitidis characterized by starting from live microorganisms of any one of the known pathogenic serotypes of the B group without inactivation, from which the extractation of the vesicles of the outer membrane and the protein antigenic complex of 65 - 95 KD molecular weight is carried out using detergent, enzyme and ultrasound combined in the treatment. The resulting product, after treatment to eliminate the nucleic acids, is purified by a dissociating treatment with detergent, ultrasonic bath and column chromatography. The multi-antigenic material so obtained is purified to obtain the protein antigenic complex of 65-95 KD molecular weight for further purification by HPLC chromatography (TSK 3000 SWG column) or affinity chromatography with monoclonal antibodies, or hydrophobicity chromatography, or ionic exchange chromatography or a combination of any two or more of them. The protein antigenic complex is then added to a solution that contains vesicles in a proportion of 15 percent ~ 3. The protein antigenic complex is then anchored to the vesicles by ultrasound treatment. The capsular polysaccharide is also added, in a proportion of 1.1 -1.4 with respect to the protein and the adjuvant in a relation ranging from 20 - 100 mcg/protein mcg. The different components of the mixture may be sterilized by cobalt 60 ionizing radiations with doses from 5 - 25 Kgy and a temperature between 1 - 4°C  before preparing the mixture or the resulting mixture may be sterilized by this procedure.

Granted: 1993-05-25
Abstract: INJECTION MOLDING MACHINE                        ABSTRACT      An injection molding machine for the making of barrels of syringes has first and second mold sections which have confronting surfaces and one of which is movable between operative and retracted positions in which the surfaces respectively abut and are spaced apart from each other.  The first section has cylindrical bores each of which is open at the respective surface and extends to an end wall adjacent a nozzle with several uniformly distributed orifices which admit heated plasticized material into the bore when the two surfaces abut.  The second section has cores each of which extends into a bore in the operative position of the one section to define with the first section a cavity for reception of plasti-cized material.  The first section has coolant-conveying channels which concentrically surround the bores, and the first section has flow restricting ports which connect the discharge ends of the orifices with the respective cavities.  The means for heating the plasticized material during flow in the first section do not extend beyond the surfaces surrounding the respective bores of the first section.  This renders it possible to place the bores and the nozzles close to each other.

Abstract: ABSTRACT OF THE DISCLOSURE     SYSTEM FOR INJECTION MOLDING ELONGATED BODIES          A tire tread (74,76,194) is injection molded by increments  in a mold cavity  (56,58,119,224,262) having an open end (110,272) closed by a trailing end (116)  of a cured section (114,228).   A temperature moderating closed end (109,207,268) prevents complete curing of a trailing portion (116) of the cured sec-tion  (114,228)  while  the  rest  of  the  section  is cured.  The mold (14,16,90,188,236) is opened so that the cured section (114,228) may be shifted to a posi-tion where the trailing portion  (116)is clamped in the   open   end   (110,272)   of   the   mold   cavity (56,58,119,224,262).   A second section (118,228,264) is injection molded in the cavity (56,58,119,224,262) and the partially cured trailing portion (126) of the cured section (114,228,264)  is cured and adhered to the  leading  portion  (130)  of  the  second  section (114,228,264) as the second section is cured.   This process may then be repeated for later sections to provide a desired length of cured tire tread stock (74,194,264).   The mold  (14,16,90,118,188,236)  may have  substantially  flat  molding  surfaces  (108)  or longitudinally and curved molding surfaces (192,210,-244).  Mold segments (204,206,208,256,258,260) for a circumferentially  curved mold cavity  (224,262)  may also be provided.
