Patent number: 10677081Abstract: There is disclosed an axial flow machine (10) comprising an annular flow path (23); a stator ring (38) comprising a plurality of stators mounted at their radially outer ends and extending into the annular flow path (23); a non-rotating body (24) axially adjacent the stator ring (38); and an annular shroud (42) disposed between the radially inner end of the stator ring (38) and the body (24). The shroud (42) is supported on the stator ring (38) and moveable relative the body (24); and the shroud (42) cooperates with the body (24) to inhibit a flow through a clearance pathway (78) therebetween.Type: GrantFiled: August 28, 2017Date of Patent: June 9, 2020Assignee: Rolls-Royce plcInventors: Alan R. Jones, Gareth J. Jones, Gary Eadon

Publication number: 20120185496Abstract: A method of retrieving information from a data source is described. The method includes providing a query sentence in a source language. A stemmed sentence is generated by removing affixes from base words of the query sentence and by removing predetermined words from the query sentence. A translated sentence is generated by translating the stemmed sentence into a target language. The translated sentence is provided to an information retrieval module operable to retrieve information in the target language from the data source based on the translated sentence.Type: ApplicationFiled: January 17, 2012Publication date: July 19, 2012Applicant: DUBLIN CITY UNIVERSITYInventors: Walid Magdy, Gareth J. Jones

Patent number: 5379382Abstract: A peripheral controller is described which is suitable for connecting a selected one of a plurality of peripheral devices to a computer system. The peripheral controller comprises programmable bidirectional line driver/receiver devices which can be operated in an input only mode, an output only mode or a bidirectional mode and which can be set into an appropriate mode by configuration control data sent from the computer system to the peripheral controller. The peripheral controller also includes a re-configurable logic array which can be configured under the control of the configuration control data to implement a particular interface required for the selected peripheral device. This increases the efficiency of use of a peripheral interface.Type: GrantFiled: April 21, 1992Date of Patent: January 3, 1995Assignee: Pilkington Micro-Electronics LimitedInventors: Gordon S. Work, Gareth J. Jones, Peter A. Albiez

Patent number: 5202637Abstract: A circuit is described which tests whether an amperometric electrochemical gas sensor monitoring the concentration of toxic gases in an atmosphere is working properly. The sensor has a sensing electrode, a reference electrode, and a counter electrode and in normal operation the potential between the reference electrodes is fixed by means of an operational amplifier. When there is gas in the atmosphere, the gas reacts electrochemically at the sensing electrode, causing the amplifier to supply electrical current to the counter electrode which results in an electrical potential to the sensor that is proportional to the amount of toxic gas in the atmosphere. The sensor is periodically tested to determine whether it is working properly by applying a pulse potential between the sensing and reference electrodes. If a current flow results then a signal is sent to an alarm device.Type: GrantFiled: September 25, 1991Date of Patent: April 13, 1993Assignee: Neotronics LimitedInventor: Gareth J. Jones

Patent number: 4776203Abstract: Circuits are described in which the sensing and the reference electrodes of a gas sensor housed within a gas monitor are connected together through the source and the drain of a field effect transistor (FET). The gate of the FET is connected to a power source to apply a first voltage to the gate when the monitor is operational and a second voltage, which is preferably zero, when the monitor is not operational, the resistance between the source and the drain of the FET being low when the second voltage is applied to the FET gate so that the sensing and reference electrodes are connected together in a short circuit. When the first voltage is applied to the FET gate, however, the short circuit is effectively broken. The circuit has output lines leading to an output device, e.g. for displaying information or an alarm. A resistor of large resistance is connected between the two output lines and, when a gas is sensed a large voltage change occurs across the resistor which can be used directly, i.e.Type: GrantFiled: October 16, 1986Date of Patent: October 11, 1988Assignee: Neotronics LimitedInventors: Gareth J.
