Patent CA-2097533-A1 (CA)
Title: Peptides having neuroprotective and immunostimulatory functions
Inventor: LEMAIRE SIMON
IPC: C07K7/08
Filed: 1993-06-02
Abstract: PEPTIDES HAVING NEUROPROTECTIVE AND IMMUNOSTIMULATORY FUNCTIONS            ABSTRACT OF THE DISCLOSURE     Histogranin having the structure   and analogs thereof having NMDA and/or AMPA receptor agonist and/or antagonist activities both in vivo by their blockade of NMDA-and AMPA-induced convulsions and in vitro by their binding and allosteric interactions with domains of the NMDA receptor complex and their potentiation of host-defense immune responses (IL-l production and IL-1.alpha. mRNA induction in alveolar macrophages) are herein described.  Histogranin is a natural compound which can be extracted from suitable tissue, e.g. bovine adrenal medulla, or synthesized using the solid-phase peptide synthesis procedure.  Histogranin and specific active fragments and analogs are potent ligands of a specific receptor linked to the NMDA and/or AMPA receptors: they block NMDA- and AMPA-receptor stimulation and therefore can be considered as good protecting agents against nerve cell degeneration due to an overstimulation of the NMDA and/or AMPA receptors, an event observed in the following brain disturbances: ischaemia, stroke, epilepsy, Alzheimer's disease, spinal cord trauma, anxiety, schizophrenia and Huntington's disease.  Some analogs are also proposed as putative antagonists of the histogranin receptor and therefore have potential beneficial use as enhancer of NMDA receptor stimulation, a process involved in learning and memory. In periphery, the ability of histogranin (and analogs) in enhancing the immune responses of immune cells such as alveolar macrophages stresses its potential use for the treatment of immune disorders (immunodeficiency related to AIDS, U.V. exposure or other immune disorders).

Patent CA-2112350-A1 (CA)
Inventor: MANARAS MICHEL
IPC: E05F15/603
Filed: 1993-12-23
Abstract: An override device is proposed to permit the manual operation of a closure which is normally driven by an electric motor. The override device comprises a manual closure driving mechanism, such as a chain engaged around a pulley, which when operated first produces the translation of a first gear along its rotation axis until this first gear meshes with a second gear connected to the output shaft of the motor which normally drives the closure. During the translation of the first gear, a switch is tripped to safely interrupt power to the motor and a mechanism is operated to disengage the motor from the output shaft. Thereafter, further operation of the chain, and therefore further rotation of the pulley, is adapted to cause the first gear to rotate instead of translating, whereby the second gear is driven into rotation by the first gear thereby causing the rotation of the output shaft and the manual operation of the closure. More particularly, the first gear is prevented from rotating with a cam mechanism associated with the pulley causing the translation of the first gear and, once the first and second gears become so engaged, the first gear can rotate with the pulley.

Filed: 1992-11-30
Abstract: A lock (19) which by physical or logical means controls human access to an objective (29) such as a restricted area or a computer system is controlled by a data processing system (10) which has access to a store of authorised users (14) and a store of complex images (15), specifically images of human faces. Each authorised user knows certain ones of the complex images, and these key images are linked to an identity statement unique to that user. On receipt of an identity statement signifying an authorised user, a matrix of images including the key images is presented to the user on a display (12), and by means of a suitable input device (20) the user must identify which images are his key images in order to confirm authorisation and be permitted access. The user and image stores (18) may be carried in credit card form as a section of an optical disk. The high security of the system results from the inability of a person to communicate adequately to another the ability to recognise a third person or other complex image.
Patent CA-2125356-A1 (CA)
Title: Vapor recovery system
Inventor: TUTTLE WILLARD N
IPC: B01D53/04
Filed: 1994-06-07
Abstract: VAPOR RECOVERY SYSTEM                   ABSTRACT OF THE DISCLOSURE A vapor recovery unit comprising a vapor inlet for taking up hydrocarbon vapor from a loading facility or the like, and thereafter alternately allowing the vapor to flow to one of at least two adsorber vessels.  Each adsorber vessel includes an entry port in the bottom of the adsorber vessel for receiving vapor.  Hydrocarbons are retained on activated carbon beds in the adsorber vessels, resulting in purified air or other carrier gas which is removed through a discharge port also in the bottom of each adsorber vessel and released through an elevated vent to the atmosphere.  Hydrocarbon vapor is desorbed from the adsorber vessel by a vacuum system and directed to a separator/absorber vessel wherein the desorbed vapor which has passed through the vacuum system is brought into contact with a hydrocarbon absorbent liquid or condenser. In use, when one adsorber vessel is taking in vapor from the vapor inlet, the other adsorber vessel is having its adsorbent bed desorbed or regenerated. When the adsorbent bed is satur-ated, or if desired on a time cycle, the process will alternate.  The adsorber vessels of the present invention do not require any flow lines or vent lines on the top of the adsorber vessels thereby allowing for easier maintenance and installation of the adsorber vessels.  The entire system is designed to be fitted to and located on a skid or skids.

Title: Technique for providing an improved signaling network for telephone systems
Inventor: LEWIS KARL M
IPC: H04Q3/00
Filed: 1994-08-31
Abstract: Abstract or the Disclosure Apparatus and a concomitant method of providing a technique, within each central office (CO) in a digital CO cluster,  for translating a destination number for a signaling message into a destination point code.  Such a CO generally contains a switching system,  for providing an interface to various station lines (telephone lines) and links to other DCOs, and/or an A-link consolidator (ALC), and an SS7 signaling processing system for providing a software based control system to properly format, address and route signaling messages.  Through the invention, the SS7  signaling  processing  system  first  translates  a destination number into a destination point code.   The destination  point  code  is  then  incorporated  into  a signaling message.  The signaling message is subsequently routed  to  a  destination node  that corresponds  to  the destination  point  code.    The  destination  point  code indicates either a CO within the cluster or an STP outside of the cluster.   Advantageously,  use of the invention eliminates the need to translate the destination number into  the  destination  point  code  without  accessing  an SS7 node outside of the CO cluster.

Title: Improved data collection method for use with chemical sensors
Inventor: BERNDT KLAUS W
IPC: G01N21/27
Filed: 1994-09-16
Abstract: A unique method for utilizing chemical sensors to determine whether a particular sample vial is evidencing bacterial growth includes directing radiation sources having closely spaced wavelengths into the sample vial. Emissions from the chemical sensor due to the two spectrally spaced radiation sources are monitored, and a ratio of their differences and sums is calculated. The inventive ratio eliminates station-to-station variation between the radiation sources or detectors, and also any lot-to-lot variations in the sensor materials. An absolute indication of the conditions within the sample vial may thus be taken with the inventive method.  In the prior art, station-to-station variations and lot-to-lot variations in the sensors resulted in varying readings for positive and negative samples. Thus, any one reading could not be utilized to make a prediction of whether a particular sample is a positive or a negative. With the inventive method, each absolute readings can be utilized to provide an indication of whether a particular sample is positive or negative at any time.
