Patent CA-2214976-A1 (CA)
Title: Low-temperature, near-adiabatic engine
Inventor: GRAY CHARLES L JR
IPC: F02B75/02
Filed: 1996-04-26
Abstract: A novel, internal combustion engine includes a cylinder, a head closing one end of the cylinder and a piston slidably mounted in the cylinder for reciprocating motion, in the usual manner, which reciprocation is converted into rotary motion by, for example, a conventional crankshaft. The top surface of the piston, cylinder head and cylinder serve as walls defining a system chamber, with a pocket formed in one of the system chamber walls for receiving fuel and serving as a combustion chamber for localized combustion therein. In one disclosed embodiment, the cylinder is divided into two sections with thermal insulation, serving as a heat barrier, disposed between the two sections and the piston has a hollow interior containing one or more heat shields spanning the hollow interior. The method of operation involves injection of fuel into a restricted area within the chamber defined between the piston head, cylinder head and cylinder, e.g., the aforementioned pocket. Air and/or exhaust gas within the chamber surrounding the restricted area of localized combustion serves as thermal insulation, protecting the cylinder walls. Operation is suitably with a peak gas temperature of 900-1100°C and a peak gas pressure of 500-1000 psi. Air is introduced in an amount providing 4-5 times the stoichiometric amount of oxygen.

Abstract: Implant cornéen intrastromal servant à modifier la courbure de la cornée pour traiter, entre autres, l'astigmatisme, la myopie et l'hypermétropie.  L'implant comprend un ou plusieurs segments arqués.

Patent CA-2221958-A1 (CA)
Inventor: DUTKIEWICZ MAREK KAROL
IPC: H04L7/04
Filed: 1996-05-22
Abstract: L'invention concerne un procédé visant à réduire les effets des transitoires sur l'étage de poursuite pour décalage en courant continu et l'étage d'extraction de la synchronisation des symboles, dans un système de transmission de données à commutation par paquets en duplex intégral ou en semi-duplex, à l'intérieur duquel la partie réception chez l'abonné fait l'objet de transitoires lorsque la partie emission chez cet abonné est FERMEE et OUVERTE. On utilise ce procédé de manière dynamique de sorte que l'étage de poursuite en courant continu et l'étage d'extraction de la synchronisation des symboles passent dans un premier mode "prêt à la distorsion" pendant la période où l'émetteur est fermé et ouvert, et de sorte qu'ils reviennent à un second mode "normal" après la transmission. Dans le mode "prêt à la distorsion", l'étage d'extraction de la synchronisation des symboles est mis à l'état "maintenu", ce qui bloque toute adaption de synchronisation supplémentaire par rapport au rythme d'horloge de décision inhérent à l'étage et, par ailleurs, l'étage d'extraction pour décalage en courant continu passe dans un mode à grande largeur de bande, ce qui évite la poursuite des variations importantes dans l'amplitude et le décalage en courant continu à la réception des signaux. En conséquence, les transitoires à l'émission (fermée et ouverte) ne perturbent pas la synchronisation du rythme d'horloge de décision avec le flux de données sur la voie d'aller, et l'étage de poursuite pour décalage en courant continu reste stable.

Title: Lifter/cutter guard
Inventor: FIGLIUZZI JOSEPH R
IPC: A01D65/02
Filed: 1998-02-17
Abstract: A crop lifting and cutting device that combines the lifting ability of a lifting guard with the cutting function of a sickle guard. The one-piece construction provides a lifter/cutter with strength to withstand and reduce damage from rocks. A litter tine is engaged with the forward portion of the sickle guard finger and follows an angular upward and rearward direction from that point. The lifter/cutter guard lifts the crop only when the plants are close to the cutter bar, insuring that any shattered grain will fall into the harvester and not on the ground.

Patent CA-2226224-A1 (CA)
Title: Fast traps for computer software instrumentation
Inventor: KNAPP HENRY H III
IPC: G06F9/318
Filed: 1997-12-30
Abstract: A computer program or a computer process is instrumented by replacing a native computer instruction with a trapping computer instruction which is the size of the native computer instruction and which, when executed, causes a trap to the kernel. A trap handler in the kernel determines that the inserted trapping computer instruction caused the trap and transfers control to a user trap handler. The user trap handler maps the trap site to a patch of instrumentation computer instructions. When the trapping computer instruction is executed, the trap handler transfers control from the kernel to the user trap handler which in turn transfers control to the patch. As a result, processing can be transferred from a source address of the computer process to a destination address of the computer process which is further from the source address than can be reached by a branching computer instruction of the size of the replaced native computer instruction. Native computer instructions in sufficient proximity to corresponding patches of instrumentation computer instructions can be replaced with branching computer instructions of the size of the native computer instruction and which transfer control to those corresponding patches. Other native computer instructions are replaced with trapping computer instructions which transfer control to corresponding patches through traps to the kernel. The user trap handler handles unanticipated traps particularly efficiently by mapping all trap sites other than those corresponding to inserted trapping computer instructions to a default patch which processes unanticipated traps. Therefore, anticipated traps are not slowed by logic verifying that the trap is anticipated. Native computer instructions which are a single byte in length are replaced with a selected, single-byte, privileged computer instruction, e.g., HALT, and the kernel trap handler transfers control to the user trap handler if a trap is caused by the selected privileged computer instruction and a user trap handler is installed. Efficiency is transferring control of a computer process through a trap to the kernel is further improved by doing substantially no more in response to a trap to the kernel than retrieving information regarding the state of the computer process prior to the trap, making that information accessible to the computer process, and transferring control back to the computer process.

IPC: G05B19/418
Filed: 1996-10-08
Abstract: A method and system (110) for monitoring both an industrial process and a sensor (104). The method and system include determining a minimum number of sensor pairs needed to test the industrial process as well as the sensor (104) for evaluating the state of operation of both. After obtaining two signals associated with one physical variable, a difference function is obtained by determining the arithmetic difference between the pair of signals over time. A frequency domain transformation is made of the difference function to obtain Fourier modes describing a composite function. A residual function is obtained by subtracting the composite function from the difference function and the residual function (free of nonwhite noise) is analyzed by a statistical probability ratio test.

Title: Method for manufacturing resin-impregnated endless belt structures
Inventor: DUTT WILLIAM H
IPC: B29C31/04
Filed: 1997-08-08
Abstract: A method for manufacturing a resin-impregnated endless belt structure is carried out on an apparatus (60) having an outer cylinder (66) and an inner cylindrical surface that is coaxial with a smaller radius cylindrical mandrel (64). An endless base structure is disposed with the outer cylinder (66) on the inner cylindrical surface. The cylindrical mandrel, having an inwardly curved nose (68), is then inserted into the outer cylinder (66) forming a nip (70) between the curved nose (68) and the inner cylindrical surface. Polymeric resin is dispensed continuously into the nip (70) while the cylindrical mandrel is gradually moved into the outer cylinder (66). The nose forces the resin into the endless base structure and expels air bubbles while forcing the endless base structure against the inner cylindrical surface. After the polymeric resin is cured, the endless belt structure, having a totally impregnated, air-bubble free endless base structure with a coating on its inner surface, may be obtained upon removal of the apparatus (60).
