Inventor: MYINT TOM
IPC: F16L55/163
Filed: 2001-09-11
Abstract: This is a specially designed Sleeve for structural repairs to large diameter pipes from inside the pipe. Normally, most of the buried pipes are being structurally repaired from outside the pipes.    This Sleeve can be used to make repairs to round and off round pipes.   It is most suitable to use for repairs to concrete , steel or cement mortar lined steel, fibreglass, PVC pipes or any large diameter pipes from 750 mm diameter and up.   The Sleeve consists of two half circular sections, the two ends of each section are equipped with special stiffened brackets. The two sections of the sleeve are to be set up by the sides of the pipe opposing each other. By tightening the bolts at both end brackets, the two sections of the sleeve will stretch tight against the wall of the pipe and thus becoming one complete circular sleeve.   Normally, a rubber gasket will be installed with the repair sleeve for a better seal against any leakage.   The repair sleeve can be made of stainless steel, carbon steel with protective coating or fibreglass.   For special application in strengthening the existing buried pipes, the sleeve can be reinforced with diagonal structural members.

Title: Emetteur-recepteur hyperfrequence a impulsions courtes
Inventor: MCEWAN THOMAS E
IPC: G01S7/35
Filed: 2000-01-21
Abstract: Des techniques harmoniques sont utilisées pour porter la technique de montage en surface (SMT) peu coûteuse et courante à des hyperfréquences élevées, techniques selon lesquelles la formation de faisceau étroit au moyen d'une petite antenne permet la production de systèmes radar d'échos d'impulsions de haute précision et fiables. La mise en oeuvre s'effectue à l'aide d'un émetteur-récepteur 24GHz à impulsions courtes qui comprend un oscillateur harmonique pulsé utilisé comme émetteur et un échantillonneur harmonique pulsé, intégrateur utilisé comme récepteur. L'oscillateur de transmission génère une oscillation très courte (0,5ns) riche en harmoniques à cohérence de phase à un sous-multiple de la fréquence d'émission en cours. Un oscillateur local de réception fonctionne à un sous-multiple de la fréquence d'émission, et est déclenché au moyen d'une synchronisation commandée afin de produire une salve très courte (0,5ns) à cohérence de phase de l'oscillateur local. Ladite salve de l'oscillateur local est couplée à un échantillonneur harmonique intégrateur pour engendrer une réplique intégrée, équivalente en temps de la radiofréquence reçue. Les techniques harmoniques permettent de surmonter quatre problèmes majeurs avec des approches non harmoniques : 1) assemblage de précision, coûteux, 2) bruit élevé de l'oscillateur local, 3) démarrage lent de l'oscillateur, et 4) faux verrouillage par injection de l'oscillateur local sur une radiofréquence externe. Ledit émetteur-récepteur peut être utilisé dans le cadre des avertisseurs de recul et de collision pour automobiles, de la télémétrie radar de précision destinée à la détection du niveau de fluides et à la robotique, de la radiolocalisation de précision, des communications à large bande, et de l'imagerie holographique à temps de résolution.

Title: Combine engine output controlled by harvesting assembly
Inventor: EHRECKE KEVIN LAVERNE
IPC: A01D41/127
Filed: 2001-11-16
Abstract: The combine of the present invention is provided with an internal combustion engine. An electronic engine controller is used to monitor and control the operation of the engine. The electronic engine controller stores at least two power curves for controlling the engine. The first power curve has a higher horsepower output than the second power curve. A harvesting assembly detector signals the electronic engine controller with a corn head signal if a corn head is mounted to the combine, or a grain platform signal if a grain platform is mounted to the combine. If a corn head is mounted to the combine the electronic engine controller derates the engine and works on the second power curve. If the electronic engine controller receives a grain platform signal, the electronic engine controller works on the higher horsepower first power curve.

Patent CA-2363732-A1 (CA)
Inventor: ANDERSSON LOA
IPC: H04L45/50
Filed: 2000-06-14
Abstract: A distributed LSR sends data from a first edge LSR, acorss a non-MPLS network, to a second edge LSR, thereby enabling a non-MPLS network to interface transparently with MPLS networks. This enables a VPN to use a public network to communicate from one portion of the network to another remote portion. The distributed LSR includes an ingress gateway logically positioned between the first edge LSR and the non-MPLS network. This ingress gateway receives label requests from the first edge LSR. These label requests are multicast to several egress gateways. At least one egress gateway sends a message back indicating that it can transmit data to the destination. In response, the ingress gateway designates that egress gateway to be a designated gateway. The egress gateway then establishes a tunnel through non-MPLS network to the ingress gateway.
