Abstract: A fuel injector including: a plurality of air swirler passages; at least one fuel supply passage arranged to supply fuel into at least one of the air swirler passages; and at least one cavity separating an exterior of the fuel supply passage from a body of the fuel injector; wherein the cavity is at least partially filled with a thermally insulating material.

Abstract: A fuel spray nozzle including a primary atomizer to discharge a flow of swirled atomised fuel along and around a fuel spray nozzle axis. The primary atomiser includes outer air swirler disposed radially outwardly of a fuel pre-filmer channel. A secondary atomiser disposed around the primary atomiser includes secondary inner air swirler to swirl flow along an inner air channel. The secondary inner air swirler disposed radially inwardly of a secondary fuel pre-filmer channel of the secondary atomiser. A primary outer air channel defined between the primary outer swirler and the secondary inner swirler. The secondary inner air swirler include splitter wall to separate swirling flow in the secondary inner channel from the primary flow of atomised fuel. The secondary inner air swirler includes primary cap wall integral with and extending radially inwardly from the splitter wall to direct flow from the primary outer channel inwardly towards the fuel spray.

Abstract: Performance profiling of software by producing a performance profile of a software processing unit and performing statistical analysis on the performance profile by matching the performance profile with at least one additional performance profile. An algorithmic approach is used to match data related to processes and/or threads and/or similar processing units (PU) over multiple performance profiles. One purpose of the matching algorithm is to identify such PU in order to enable computation of an accumulated or averaged dataset over multiple profiling periods. Various matching strategies, filters, and preprocessing techniques are described, together with level of reliability estimation.

Abstract: The invention relates to an improved design of wire tensioner for use in electric wire fences. As well as attaching a wire to a fence post, and tensioning the wire, the device also insulates the wire from the metal post. The device comprises an insulating means or body which has an engagement face for engaging with internal surface of a fence post and a spring for applying a tensioning force to the wire. Any changes in the length of the wire due to ambient temperature variation can be absorbed by the spring, thus minimising maintenance adjustments of the wire tension. The spring may also be used to press the engagement face against the surface of the fence post, and therefore hold the device in position. The present invention also provides for installing the (wire tensioner) devices inside a fence post (which is fitted with a cover) and which contains the high voltage (HV) and earth wire connections.

Abstract: An assembly wherein inexpensive and essentially maintenance-free disposable sensors may be used in conjunction with a metal making lance. The assembly contemplates the use of disposable sensors that are accommodated by a sensor feed tube disposed interiorly or exteriorly of a conventional metal making lance. The sensors may be selected to detect one or more characteristics of the metal being treated and/or operating conditions of a metal treatment vessel.
