Title: Blow-out prevention mechanism for windows
Inventor: SILVERMAN ARTHUR
IPC: E06B3/44
Filed: 1999-08-24
Granted: 2002-11-12
Abstract: A storm-resistant window includes a mechanism for preventing the blowout of a movable sash when wind pressure pulls the sash outwardly. In a single hung window having a slidable lower sash, the mechanism consists of a first rib projecting downwardly from the bottom rail of the lower sash and a second rib projecting upwardly from the top of the sill member of the window frame. In a closed position of the window, the first rib lies inwardly adjacent the second rib such that, if wind pressure pulls the movable sash outwardly, the first rib will contact the second rib, preventing the bottom rail of the movable sash from moving outwardly. In an alternate embodiment, one of the ribs may be replaced with a channel, so that the remaining rib is received in the channel in the closed position of the window.

Title: Method of patching downhole casing
Inventor: VLOEDMAN JACK
IPC: E21B29/10
Filed: 1999-10-22
Granted: 2004-08-31
Abstract: A method for lining a portion of a casing affixed within a well bore a distance below an upper end of the well bore with a viscoelastic pipe having an upper end, a lower end, and an outer diameter greater than the inner diameter of the casing is provided.        The outer diameter of the pipe is reduced so that the outer diameter of the pipe is less than the inner diameter of the casing.        The reduced pipe is then lowered into the casing to a predetermined depth where the upper end of the reduced pipe is positioned a distance below the upper end of the well bore. The reduced pipe is then allowed to expand against the internal wall of the casing, thereby forming a fluid tight seal with the casing and effectively sealing any breaches in the casing. So that the outer diameter of the reduced pipe remains less than the inner diameter of the casing as the viscoelastic pipe is being passed down the casing, the reduced pipe is maintained in tension as the reduced pipe is being passed down the casing. Tension is maintained on the reduced pipe by suspending an amount of weight from the lower end of the pipe prior to passing the pipe down the casing. The amount of weight is sufficient to maintain the pipe in tension as it is being passed down the casing so that the outer diameter of the pipe remains less than the inner diameter of the casing as the pipe is being passed down the casing.

Title: Distributed switch and connection control arrangement and method for digital communications network
Inventor: GODIWALA NITIN D
IPC: H04L12/28
Filed: 1999-05-01
Granted: 2009-11-03
Abstract: A network (10) includes devices such as computers (12(1)-12(8)), and the like, interconnected by switching nodes (11(1)- 11(6)). At least some of the devices are configured to determine the topology of the network. In determining the network topology, a device operates in a series of iterations, in each iteration transmitting a request message over a path to determine whether an additional entity is present in the network. If an additional entity is present at the end of the path defined in the request message, the entity will generate a response, which is provided to the device. The device, on receiving the response, will add information concerning the entity to a network topology database. At least some the devices, as they discover additional switching nodes in the network, will attempt to configure the switching nodes. In that operation, the devices interact with the switching nodes in connection with a locking protocol to ensure that only one device attempts to configure each switching node. Each device, after it determines the network topology, and when it needs to transfer information with another device, can determine an appropriate route using the newtork topology information in its network topology database. After determining the appropriate route, the device will load routing information into the switching nodes (11(1)-11(6)) to enable them to forward messages containing the information to be transferred thereamong.

IPC: F04B43/04
Filed: 1998-11-06
Granted: 2008-12-30
Abstract: L'invention concerne un réseau de pompage présentant une pluralité de cellules élémentaires, un procédé de fabrication du réseau et un procédé de pompage de fluides utilisant ce réseau de pompage. Les cellules ont chacune un corps formant une cavité contenant des électrodes supérieure et inférieure, alimentées sélectivement par les connexions électriques et présentant des surfaces courbées faisant face à l'autre électrode. Une membrane bistable est montée de sorte que sa partie principale se trouve logée dans la cavité entre les électrodes de manière que cette membrane soit déviée vers les surfaces supérieure et inférieure afin de s'y adapter. Une conduite latérale est placée au niveau d'au moins une extrémité du corps en vue d'une communication fluidique avec la cavité. Les conduites latérales sont reliées de manière opérationnelle à une partie de la membrane montée dans le corps et sont ouvertes et fermées par un mouvement de la membrane. La membrane régule l'écoulement de fluide en entrant en contact avec ou en s'éloignant d'une conduite verticale reposant sur au moins une surface courbée. Les cellules sont interconnectées pour former un réseau de pompage dans lequel l'activation des électrodes fait bouger la membrane entre les électrodes et fait entrer ou sortir le fluide du corps. Le réseau de pompe préféré comprend des ensembles de trois groupes de cellules de sorte que le fluide s'écoule dans une première cellule à partir d'une source de fluide, qu'il soit expulsé vers une seconde cellule à travers une conduite verticale, puis expulsé via une conduite latérale vers une troisième cellule pour en être ensuite expulsé. L'écoulement du fluide s'effectue par l'activation des électrodes.
