Title: Pressure independent control valve
Inventor: CARLSON BENGT A
IPC: F16K31/122
Filed: 2000-08-17
Granted: 2009-06-02
Abstract: Simple APCV, ADPCV and PICV's are provided. The APCV's are referenced to the atmosphere and control the gauge pressure, either upstream or downstream. The ADPCV's are the same as t he APCV's, differing in that they are not referenced to the atmosphere. They are instead referenced to a second point in the flui d flow system and control the differential pressure. The PICV's are control valves connected in series with ADPCV's and control the fluid flow rate through the valve independently of variations in the line pressure. A preferred APCV has a valve body (1) with connections for a single-phase fluid line and a flow passage between the inlet (2) and the outlet (3) of said fluid line, with an opening having a defined seat orifice (7) intersecting the flow passage. A moveable assembly, comprising a disk (5) or cup is connected to a pressure sensing member (4), having essentially the same effective surface area. The moveable assembly, is biased by a force , and is free to automatically move to any intermediate position between fully open and closed, producing a desired outlet pressure which minus the reference pressure, times the effective surface area of the disk or cup generates an opposing force equal to the biasing force.

Abstract: A fill cup is provided for a fluid filter having a housing and an end plate which enclose a filter element. The end plate has an inlet port for receiving unfiltered fluid and an outlet port from which flows filtered fluid. The fill cup includes a base having openings formed therein, a cylindrical rim which surrounds the base, and a hollow tube which extends axially through the base and rim. The tube forms a stub which projects away from the base and which is adapted to be coupled to the outlet port of the filter. The tube also forms a hollow standpipe which is aligned with the stub and which projects away from the base and into an interior of the cup. When the filler cup is mounted on the filter, the cup openings communicate fluid to the inle t ports of the filter, and the hollow tube prevents unfiltered fluid from directly entering into the outlet port and communicates air from the filter to atmosphere as the filter is filled with fluid. The stub has external threads for screwing into the outlet port of the filter, and the base of the cup sealingly engages a seal mounted on the filter end plate.

Granted: 2006-03-28
Abstract: A "segmented" CAN bus is disclosed. The "segmented" CAN bus extends the cabling scheme of a CAN network to permit isolation of individual nodes of identical type when needed and the ability for a host to determine the network topolog y. In addition, the CAN bus cabling scheme automatically assigns unique addresses to nodes and guarantees that the network will always be properly terminated. Th is eliminates the need for jumpers, DIP witches, pre-installation programming, or other hardware means requiring human intervention to uniquely identify the nodes on the network. Furthermore, because the physical node topology is determinable, equipment installation and anomaly diagnostics are facilitated. The present invention contemplates that this technique can be applied to various local area networking schemes.

Abstract: A bi-stable micro-machined electro-mechanical system ("MEMS") switch. In a preferred embodiment, the bi-stable MEMS switch is used in an NXN optical signal switching system. Spring arms act in conjunction with a hollow beam portion of a movable center body of the switch to accommodate strain in the arms as the switch is moved from a first position to a second position, thus avoiding buckling of the spring arms. Both the first and second switch position occur at local minimums of mechanical potential energy, thus providing two stable switch states. The center body is moved in relation to static portions of the switch by an actuator, such as an electro-static comb drive.

Abstract: The present invention provides a method for at least in part decreasing the production of an aberrant protein in a cell, said cell comprising pre-mRNA  comprising exons coding for said protein, by inducing so-called exon skipping in said cell. Exon-skipping results in mature mRNA that does not contain the skipped exon which leads to an altered product if said exon codes for amino acids. Exon skipping is performed by providing a cell with an agent capable of specifically inhibiting an exon inclusion signal, for instance an exon recognition sequence, of said exon. Said exon inclusion signal can be interfered with by a nucleic acid comprising complementarity to a part of said exon. Said nucleic acid, which is also herewith provided, can be used for the preparation of a medicament, for instance for the treatment of an inherited disease.

Title: Simultaneous multi-user document editing system
Inventor: WALKER RICHARD
IPC: G06Q10/00
Filed: 2001-08-21
Granted: 2007-12-04
Abstract: A system and methods for simultaneous editing of one or more documents by two or more distinct users is disclosed. Each document is divided into a number of mutually exclusive sections, which together contain the entire document. Each section is stored in a separate data container. Each document has primary data of a primary data type. The containers that store the primary data for each document have a common parent container, which is at the head of a document sub-tree corresponding to the document. A document may also include embedded data, which may be of the same or a different type than the primary data. The embedded data is typically stored in embedded data containers, which are typically child containers of the primary data containers. Each of the parent containers is a child container of a root container, which is at the head of a container tree in which all documents in a workspace are stored. Each workspace also includes a member list. The system may include more than one workspace, and may include users who are members of more than one workspace.  Editors are provided for editing documents and embedded data of a number of data types that are supported by the system. Each editor is configured to allow a member to edit data in a section of a document. Typically, data may only be edited after obtaining an exclusive lock for the container in which the section is stored. However, in some cases, data may be edited without first locking the associated container and the modified container may be blindly posted. Different sections of a document may be simultaneously locked by different members, allowing the members to simultaneously edit the two different sections. Editing changes to a document are posted by each editor to a workspace server, which then broadcasts the changes to all connected members of the workspace, allowing members to view changes to a document after they are posted.

Abstract: A system and method for supporting mobile Internet communication is provided which employs a plurality of Routers and a plurality of Mobile Nodes (MNs).  Each Router has a unique communication address. Each MN is associated with a home Router.  Each Router has an associated Mobile Node Location List identifying each MN for which the Router is the home Router and the communication address of a Router corresponding to a current location of each such MN. Each MN is movable from an old location where the MN communicates with the Internet via one Router to a current location where the MN  communicates with the Internet via a different Router. Communication at the current location via the different Router is established by communicating to the MN's home Router the communication address of the different Router as the communication address corresponding to the MN's current location. Accordingly, a data communication from a corresponding node (CN) to a selected MN is communicated to the selected MN by accessing the Mobile Node Location List of the selected MN's home Router to determine the communication address corresponding to the selected MN's current location and directing the data communication to that determined communication address.
