Patent CA-2216532-A1 (CA)
Title: Inhibitors of farnesyl-protein transferase
Inventor: DESOLMS S JANE
IPC: A61P35/00
Filed: 1996-03-25
Abstract: The present invention comprises analogs of the CA1A2X motif of the protein Ras that is modified by farnesylation in vivo. These CA1A2X analogs inhibit the farnesyl-protein transferase and the farnesylation of certain proteins. Furthermore, these CA1A2X analogs differ from those previously described as inhibitors of farnesyl-protein transferase in that they do not have a thiol moiety. The lack of the thiol offers unique advantages in terms of improved pharmacokinetic behavior in animals, prevention of thiol-dependent chemical reactions, such as rapid autoxidation and disulfide formation with endogenous thiols, and reduced systemic toxicity. The compounds of the instant invention also incorporate a cyclic amine moiety in the A2 position of the motif. Further contained in this invention are chemotherapeutic compositions containing these farnesyl transferase inhibitors and methods for their production.

Patent CA-2219473-A1 (CA)
Title: Laser gas analyzer and method of operating the laser to reduce non-linearity errors
Inventor: KIDD GARY E
IPC: G01N21/39
Filed: 1997-12-24
Abstract: A method of operating a laser and a gas analyzer to reduce low frequency and high frequency power non-linearity errors passes a laser beam through a sample gas to a detector. Intensity measurements are taken and compared to a reference set of measurements. The reference set of measurements can be calculated by measuring pressure and temperature of the sample gas. The laser wavenumber tuning width is locked to tune a high frequency of an absorption path fringe to a predetermined reference value. The analyzer can be operated without taking a reference set of measurements and the analyzer is much smaller than previous analyzers.

Patent CA-2235857-A1 (CA)
Title: Svc routing in network with static routing tables
Inventor: BEHKI NUTAN
IPC: H04L45/24
Filed: 1996-10-25
Abstract: A method is disclosed for establishing a switched virtual circuit in a digital network having network nodes with static routing tables. The static routing tables contain at least primary and alternate routing data. When a node is unable to forward a call over its outgoing primary route due to congestion or physical failure and its alternate route is the same as the route on which a call setup request arrived, it clears the call at that node and sends a crankback message to the preceding node, which responds to the crankback message to attempt to dynamically re-route the call over the alternate route stored in the routing table of the preceding node. If the attempt is unsuccessful, it sends the message back to the next preceding node and so on.

Title: Plant for manufacturing cement clinker
Inventor: JESSEN EJNAR
IPC: C04B7/44
Filed: 1997-02-07
Abstract: The present invention relates to a plant for manufacturing cement clinker. The plant consists of a preheater, a calciner in which the raw material is calcined at a temperature of more than 800 °C and where fuel and oxygen-containing gas are fed to the lowermost zone of the calciner, and a kiln.  The object of the invention is to provide a plant for manufacturing cement in which it is possible to burn lumpy fuel in a calciner, while simultaneously maintaining the possibility of increasing the time of retention and possibly the temperature of the material being fed to the lowermost zone in the calciner. This object is achieved according to the invention in that the calciner is provided with a fixed bottom (27) allowing combustible material fed to the calciner to be deposited on the bottom and in that oxygen-containing gas is fed horizontally to the calciner through openings in the lowermost zone of the calciner. That the oxygen-containing gas is fed horizontally entails that the gas is introduced through the vertical sides/walls of the calciner, and not through the bottom.

Title: Ultrasonic inspection method and apparatus
Inventor: FEARNSIDE RICHARD L
IPC: G01N29/04
Filed: 1998-10-07
Abstract: Radially spaced calibration holes are drilled parallel to the exterior surface of a cylindrical shell for a dryer roll. An ultrasonic transducer is mounted in a fixture filled with a coupling medium which allows for adjustment of the spacing and angle of the transducer which traverses the shell as it is rotated. A computer calculates the time the signal takes to travel from and return to the transducer and the depth from which the signal returns. A clear signal corresponding to holes up to one inch from the surface are found by adjusting the ultrasonic transmission angle. This angle is approximately 23 degrees from a normal to the casting surface. The calibrated transducer traverses the surface of the casting. The stored data may be used in maintaining the dryer roll formed from the casting.

Title: Method and system for checking the operability of a breathing equipment
Inventor: LUNDBERG MATS
IPC: B63C11/22
Filed: 1997-02-18
Abstract: A system checks the operability of electrical-based components (10, 14, 17, 19) in a breathing equipment (16). such as a Self-Contained Breathing Apparatus (SCAB), for example. The system includes a microprocessor (7) which is communicatively coupled with the electrical-based components (10, 14, 17, 19). After a power-up of the breathing equipment, the microprocessor (7) receives a signal from the electrical-based components (10, 14, 17, 19) indicating the operational state of that particular component.  If the signal is not received by the microprocessor (7), or the signal deviates from a predetermined threshold, then that electrical-based component (10, 14, 17, 19) has failed to function properly. In that case, a visual indication of the failure is provided to a user of the breathing equipment (16). In addition, the system provides a visual identification of whether the microprocessor (7) itself is malfunctioning. A method is also provided for checking the operability of electrical-based components (10, 14, 17, 19) in the breathing equipment (16).
