Title: Handle-mounted locking apparatus and method
Inventor: YU SANDY TAI SHEUNG
IPC: E05B47/00
Filed: 1997-03-21
Abstract: A locking apparatus for use on a handle operable to be gripped by a user's hand.  The apparatus includes a moveable actuator operable to be moved by a portion of a user's hand when gripping the handle.   A first moveable blocking member is connected to the handle and is operable to be moved into an enabling position in which movement of the movable actuator is enabled and is operable to be moved into a blocking position in which movement of the actuator is blocked by the blocking member interfering with movement of the actuator.  A first mounted magnet is connected to the first blocking member and is disposed in a position on the handle such that at least one of the user's fingers will be adjacent the first mounted magnet when the handle is gripped.   The  first mounted magnet  is operable  to cooperate with a first adjacent magnet placed adjacent the first mounted magnet to move the first blocking member between the blocking and enabling positions.  A method of unlocking an actuator on a handle includes gripping the handle such that an adjacent magnet on a finger ring worn by the user is placed adjacent a mounted magnet on the handle,  attracting the mounted magnet with the adjacent magnet thereby moving a first blocking member out of the path of an actuator on the handle and squeezing the handle and the actuator to move the actuator relative to the handle.
Patent CA-2200642-A1 (CA)
Inventor: MOONEY JOSEPH A
IPC: F24C7/08
Filed: 1997-03-21
Abstract: A monitor and warning system for use with an appliance such as a stove for providing an alarm when the system senses that the appliance has been left on and in an unattended condition for more than a predetermined time interval.  The system is designed to be activated when the appliance is sensed as being on, such as having a temperature greater than the ambient temperature.  The activated system then continually reacts to the presence of the user to reset a timing device to a start condition.  In the event the timing device is allowed to run without being reset for a predetermined time interval, it provides a signal to an alarm section which sounds an alarm or provides other types of warning signals in the area of the appliance or elsewhere.  The system remains in an inactive condition when the appliance is not in use but is designed to be activated by a condition of the appliance and to then carry out its monitoring process for detecting an unattended condition without the user having to remember to arm the system.

Title: Fiber-optic interface system
Inventor: STASZ PETER
IPC: H04B10/00
Filed: 1995-10-03
Abstract: A fiber-optic data-link (10) used to interface a remote process variable sensor/transmitter (14) to a local process control system (12) includes a local light source module (16) and a remote interface module (18) interconnected by one or more optical fibers (20, 22). Energy for operating the remote interface module (18) and its associated process variable sensor/transmitter (14) is provided by light energy transmitted from the local site to the remote site and converted at the remote site to an electrical signal. The local light source module (16) and the remote interface module (18) each may include a microcontroller (24, 34). The controllers not only control the flow of status messages in either analog or digital analog form simultaneously from the remote site to the local site, but also ensure the integrity of the system and minimize the amount of optical power delivered to the remote site.

Title: Method and device for the generation of ultrashort optical pulses
Inventor: CAPONI RENATO
IPC: H04B10/61
Filed: 1997-06-27
Abstract: A method and apparatus for generating ultrashort optical pulses.   The apparatus comprises a source for producing pulses in a first band, a compensating optical fibre, and a span of dispersion-shifted optical fibre.  The compensating optical fibre receives the pulses generated by the source and has a minimum dispersion in a second band different   from   the   first   band   and  dispersion characteristics for compensating phase distortion due to chirp of the pulses.  The dispersion-shifted optical fibre is coupled in series to the compensating optical fibre and has a dispersion minimum in the first band for adjusting the peak power level of the pulses emitted by the source to produce self-phase modulation in the dispersion-shifted fibre.  Pulse peak power is selected so as to coincide with the vertex of the parabola plotting the square of the duration of the outgoing pulse versus the peak power of the incoming signal.

Les fils conducteurs sont de calibre à supporter un courant provoquant une force de répulsion dont l'intensité est susceptible de briser de la glace ou du givre sur l'élément stru ctural par l'éloignement des fils conducteurs l'un de l'autre en réponse à la répulsion . Les fils conducteurs ont des propriétés de rigidité et d'élasticité telles qu'il s retrouvent leur forme autour de l'élément structural après l'éloignement causé p ar la répulsion.
Patent CA-2211939-A1 (CA)
Inventor: NAPOLI GUIDO DI
IPC: A61K8/368
Filed: 1997-07-30
Abstract: A process to produce rhein derivatives of formula (I).   wherein R a is H, acyl, alkyl or aromatic group. The process is characterised by the formation of a protected diphenylketone by reaction of compounds of formula (IX) and (X), where R1-4 and Hal are defined in the specification.   Said protected diphenylketone is treated with a strong base and then with an alkyl- or aromatic alcohol/amide/mercaptan; the resulting product is treated with a strong concentrated acid, followed by treatment with a diazotising agent and with a strong acid in aqueous medium; the resulting product is deprotected and, when R a in formula (I) is acyl, suitably acylated. The process allows to obtain highly pure derivatives of formula (1), being in particular totally free from aloe-emodin.

Title: Source capture system for an air cleaning system
Inventor: DIACHUK WOLODYMYR
IPC: B01D50/00
Filed: 1996-03-28
Abstract: A source capture system (110, 152) for capturing contaminated air from an industrial process (124) includes structure both for continuously capturing a contaminated air volume (120) with an ambient air volume (171, 173) to produce a mixed air volume (180) which is then transferred to an air clean apparatus (114, 156) or the like. The source capture system (110, 152) recognizes that air volumes will exhibit different characteristics traveling through an air treatment system, and that certain of those characteristics such as cloud-like formation (140) and contaminated air volumes (120) having significant gaseous phase vapor components are undesirable and operate to decrease the overall effectiveness of the air treatment system (114, 156), regardless of what type of technology is used for the air cleaning apparatus (114, 156). Accordingly, the source capture system (110, 152) is designed in such a way as to reduce the occurrence of cloud-like formations and increase the condensation of mist/vapor components of the air volume presented to the air cleaning apparatus (114, 156).

Title: Method and apparatus for rapidly rendering computer generated images of complex structures
Inventor: SOWIZRAL HENRY A
IPC: G06T15/40
Filed: 1997-12-16
Abstract: The image rendering system (20) of the present invention rapidly renders graphical image of complex structures. A complex structure is represented by a plurality of objects that can be organized into an object hierarchy. The image rendering system (20) projects a plurality of rays (55) from a given vision coor dinate. For each projected ray, the image rendering system (20) determines with which objects in the object hierarchy are intersected by the ray (55). The image rende ring system (20) then determines which object among those intersected by the ray (55) is closest to the given vision coordinate and adds that object to a set of visible objects. As objects are added to the set of visible objects, each object is rendered on t he display in accordance with a current vision coordinate. Since the process of add ing objects to the set of visible objects is decoupled and run asynchronously from t he process of rendering visible objects on the display, the image rendering system (20) is capable of rendering objects at real-time frame rates.
