Title: Method and apparatus for distance vector routing on datagram point-to-point links
Inventor: PERLMAN RADIA J
IPC: H04L12/56
Filed: 1991-10-11
Abstract: METHOD AND APPARATUS FOR DISTANCE VECTOR ROUTING ON DATAGRAM POINT-TO-POINT LINKS               ABSTRACT OF THE DISCLOSURE         A technique for distributing updated distance vectors used in routers, which are connected by point-to-point links having datagram service.  Distance vec-tors are used by routers to route messages over the most desirable paths, but must be continually modified as a result of update messages passed between routers, to reflect changes in network topology. Datagram ser-vice does not normally ensure that such update messages will reach other routers,  but the technique of the invention uses unique sequence numbers on all informa-tion packets containing distance vector update mes-sages,  and achieves efficient and timely distribution of updated distance vector information with only a modest storage requirements. Unlike reliable service, which requires each message to be delivered exactly once and in the order sent, the invention allows subse-quent update messages to be delivered to the same neigh-boring router even if previous messages have not yet been received and processed.  The invention also pro-vides for retransmission of unacknowledged distance vector information, but without the burden of having to store all transmitted packets until they are acknow-ledged.

Patent CA-2053482-A1 (CA)
Title: Ultrasonic detection using tunneling microscope
Inventor: MOREAU J T A
IPC: G01N29/22
Filed: 1991-10-15
Abstract: Abstract of the Disclosure A scanning tunneling microscope is provided which is capable of detecting high frequency (1.8 to 12.5 MHz) acoustic waves.  Acoustic pulses arriving at a conducting surface are detected as a high frequency perturbation of the tunneling current.  Near and below the rolloff frequency of the current to voltage amplifier, the instantaneous displacement of the surface can be reconstructed.  For higher frequencies, the non-linear (rectifying) properties of the tunneling behavior allow the detection of the envelope (and hence the time of arrival and total amplitude) of the acoustic burst.  The technique's sensitivity is comparable to that of optical detection schemes but offers much better lateral resolution.

Abstract: PR?CIS Poulie de type "menée" entraînée par une courroie, utilisée dans une transmission à courroie à vitesse variable, dans laquelle des roues dentées de forme généralement tronconique viennent s'interposer chacune entre deux crémaillères circulaires placées à angle par rapport au plan radial de façon à permettre la variation du diamètre d'enroulement de la poulie en fonction de la force radiale exercée par la courroie et du couple à transmettre. Le diamètre d'enroulement de la poulie est inversement proportionnel à cette force radiale mais est aussi proportionnel au couple de charge. L'utilisation de roues dentées roulant sur des crémaillères permet notamment d'obtenir un très faible coefficient de frottement, de minimiser l'hystérésis, de diminuer le temps de réaction de la poulie et de réduire l'entretien requis.

Abstract: Repetitive phenomena cancelling controller arrangement for cancelling unwanted repetitive phenomena comprising known fundamental frequencies. The known frequencies are determined and an electrical known frequency signal corresponding to the known fundamental frequencies of the unwanted repetition phenomena is generated. A plurality of sensors (S l...S n) are employed in which each sensor senses residual phenomena and generates an electrical residual phenomena signal representative of the residual phenomena. A plurality of actuators (A l...A n) are provided for cancelling phenomena signals at a plurality of locations, and a controller is utilized for automatically controlling each of the actuators as a predetermined function of the known fundamental frequencies of the unwanted repetitive phenomena and of the residual phenomena signals from the plurality of sensors. In this arrangement the plurality of actuators operate to selectively cancel discrete harmonics of the known fundamental frequencies while accommodating interactions between the various sensors and actuators:

Abstract: MIAB WELDING MACHINE                 ABSTRACT OF THE DISCLOSURE    An apparatus for magnetically impelled arc butt welding (MIAB), particularly for welding pipes, is described.  The welding head of the apparatus is disposed outside the pipe being welded.  The apparatus has a pair of clamps which are operable so as to receive the pipes from above (i.e., the clamps open in an upward direction, so the pipes may be lowered into the apparatus).  A MIAB welding method for welding pipes is also described.  The method requires that the pipe movement be monitored during the forging step of the welding.  By monitoring the pipe movement, the amount of pipe which is lost as "upset" during the welding operation may be calculated.
