Title: Thermoplastic yarn draw texturising process - has preparatory tensioning and heating phase for initial orientation to prevent melting and breakage
IPC: D02G1/02
Filed: 1973-10-31
Abstract: The system to prepare and feed Unstretched thermoplastic yarns are prepd. and fed into a stretching and false twisting equipment, using a device which incorporates a section with adjustable tensioners and a heated stretching stud with automatic disengagement of the yarn before it is drawn off into the draw texturising unit. The system gives an initial orientation and heating phase to the yarn matl. which reduces the risk of yarn breakage or melting during the draw texturising process, increasing throughput speeds and reducing lost time in yarn repair.

Title: Navigation manager for navigating a hierarchical user interface represenation
Inventor: CLARK DAVID J
IPC: G06F17/30
Filed: 2000-03-16
Abstract: A navigation manager co-operable with a user interface renderer manages one or more navigation units and maintains a navigation unit cursor which identifies one navigation unit as a current navigation unit. Each navigation unit may be associated with another unit, managed by the same manager, in such a way that forward and backward navigation between units may be considered. The navigation manager takes into account the associations between the navigation units to determine the correct sequence of navigation units for forward and backward navigation, and also takes into account whether the items represented by each navigation unit include eligible items or items for which data entry is incomplete. In this way navigation units for which all items represented by the navigation unit are ineligible can be passed over so that they never become current. Similarly forward navigation can be discouraged if the current navigation unit represents one or more items for which data entry is incomplete.

Title: Intelligent valve positioner tuning
Inventor: HANSEN PETER DANIEL
IPC: F16K37/00
Filed: 2000-09-06
Abstract: A valve position controller tuning method avoids impact of friction in valve positioner tuning by building a dynamic model of a valve positioner from a monotonic open-loop response of a valve stem position to a change in valve position controller output. To this end, a model form is selected based on the type of pneumatic actuator and relay that controls valve flow modulating of member motion, and the valve position controller is operated in an open-lop mode. The method includes changing a valve position controller output signal to cause the valve positioner to move a valve flow modulating member, connected to valve positioner, monotonically from one stuck position to another stuck position immediately after a motion in that same direction. When a valve stem position reaches a position threshold, a first valve stem position change and a corresponding time change are measured. The method includes measuring valve stem position changes at times that depend on the first measured time change. Using the measured results, valve positioner response parameters are calculated for the selected model form from which valve position controller tuning constants are calculated.

Title: Fire and explosion suppression system
Inventor: DUNSTER ROBERT GEORGE
IPC: A62C5/00
Filed: 2002-03-28
Abstract: A fire and explosion suppression system comprises a source (5) of high pressure water which is fed to a misting nozzle (13) at one input of a mixing unit (6), and a source (14) of high pressure inert gas, such as nitrogen, which is fed along a pipe (20) to another input of the mixing unit (6). Inside the mixing unit (6), water mist, in the form of an atomised mist of very small droplet size is mixed with the pressurised gas and exits the mixing unit (6) at high pressure and high velocity along a pipe (22) and is thence discharged though spreaders (26,28). The source (5) of the water is pressurised by a feed (30) from the source of pressurised inert gas. The mass flow rate of the water will therefore reduce as the pressure of the gas decays. This tends to maintain the ratio of the mass flow rate of the water to the mass flow rate of the gas constant. This is found to produce and maintain an advantageous distribution of droplet size in the discharged mist. A control unit (10) adjusts a metering valve (7) in dependence on the mass flow rate or the pressure of the gas in order to adjust the ratio as necessary to maintain its value constant.

Title: A method and system for controlling an internal combustion engine.
Inventor: LEWIS DONALD JAMES
IPC: F02D41/02
Filed: 2002-06-11
Abstract: A method and system for controlling an internal combustion engine 13 which is coupled to an exhaust system 49 having an emission control device 52, the method comprising determining the amount of oxidants stored in the emission control device and adjusting the air-fuel ratio based upon that determination. The amount of oxidants stored in the emission control device may be estimated or may be a measured value. The emission control device may comprise multiple catalyst bricks. The air-fuel ratio may be adjusted so as to prevent the amount of stored oxidants from becoming less than a first predetermined amount, which may be zero, and more than a second predetermined amount, which may be the total oxidant storage capacity. The method may comprise selecting a target oxidant amount and adjusting the air-fuel so as to maintain the amount of oxidants stored in the emission control device at that level. The air-fuel ratio may be adjusted to be richer when the determined amount of oxidants stored in the emission control device is greater than the target amount, and made leaner when it is less than the target amount. The degree of this adjustment may be fixed if the difference between the target amount and the determined amount is large and proportional if the difference is a small amount.
