Publication number: 20120264546Abstract: A method for playing and scoring a golf game, comprising determining an actual time it takes a team to complete a golf hole, determining a number of strokes taken by the team in completing the golf hole, multiplying the number of strokes taken by the team in completing the golf hole by a predetermined amount of time to determine an added shot time, determining a total hole time by adding the added shot time to the actual time it takes the team to complete the golf hole, and recording the total hole time on a score keeping means.Type: ApplicationFiled: April 16, 2012Publication date: October 18, 2012Inventors: ISAAC S. DANIEL, STEPHEN HAYWARD

Patent number: 7488942Abstract: A gas sensor of the type having a housing defining a chamber within which light is transmitted from a source to a detector through an optical path, includes internal mirror portions having part ellipsoidal shape. Light is transmitted from a source to a detector via the reflective portions. The detector is arranged to sense light only from a limited range of angles, such that only light transmitted through a defined optical path reflected off the two reflective portions from the source reaches the sensor. This ensures that there is a constant optical path from the source to the detector, which improves the signal to noise ratio of the device.Type: GrantFiled: November 7, 2003Date of Patent: February 10, 2009Assignee: E2V Technologies (UK) LimitedInventors: Graham Paul Hopkins, Andrew Stephen Hayward

Patent number: 7420171Abstract: A gas sensor comprises a body on which is mounted an optical source and a detector means sensitive to light from the source. The body further comprises a channel arranged to admit gas, the channel comprising an elongated groove having reflective surfaces defining a folded optical path for light from the source. The groove is arranged as a serpentine shape or spiral shape so that light from the source to detector travels around the groove being internally reflected within the shape.Type: GrantFiled: December 5, 2003Date of Patent: September 2, 2008Assignee: E2V Technologies (UK) LimitedInventors: Graham Paul Hopkins, Andrew Stephen Hayward, Brian Thomas Alfred Wells

Publication number: 20050156101Abstract: A method for detecting perturbation of a physical system from a reference state associated with a reference parameter (?0) to a perturbed state associated with a perturbed parameter (?) includes firstly deriving the reference parameter (?0). A reference vector (F) is then derived which describes the system's state at the reference parameter (?0). A measurement-related vector (Z) associated with a perturbed state of the system is then subtracted from the reference vector (F) to provide an error vector (E). The error vector members are summed and normalised by division of a summation of elements of a vector (F?) representing a derivative (f(?0??)e) of a reference itself represented by the reference vector (F), the derivative (f(?0??)e) being evaluated at the reference parameter (?0). This provides a result equal to the difference (?-(?0) between the perturbed parameter (?) and the reference parameter (?0).Type: ApplicationFiled: March 19, 2003Publication date: July 21, 2005Inventors: Stephen Hayward, Timothy Cox, Marie Anderson

Patent number: 6150742Abstract: An energy storage and conversion apparatus (1) comprising a containment (5) defining a vacuum chamber (7), a substantially vertical shaft within the vacuum chamber (7), a stator (11) on the shaft (9), and a cylindrical rotor (13) which, in use, is driven by the stator (11) to store energy as kinetic energy of the rotor (13) and acts with the stator (11) as a generator to release energy, wherein the rotor (13) is supported by the shaft (9) via an end cap (29), positioned at the upper end of the cylindrical rotor (13), which engages the shaft (9). The rotor (13) is suspended from a pin bearing (31) which is attached to an end cap (29). The pin bearing (31) sits in a bearing cup (37) mounted in a damper (39) at the end of the shaft (9). A magnet bearing (43) is provided at the lower end of the rotor (13) to assist in positioning the rotor (13) relative to the stator (11).Type: GrantFiled: April 7, 1998Date of Patent: November 21, 2000Assignee: British Nuclear Fuels PLCInventors: Roger Eric Horner, Colin David Tarrant, Ian Crombie, Geoffrey Martin Barker, David Stephen Hayward

Patent number: 5829362Abstract: A fabricated metal stillage for storing and/or transporting a plurality of drums containing hazardous material, such as radioactive waste, comprising a rectangular planar base having a post extending upwardly from each corner. Each post is hollow and is provided with a support pad at an end remote from the base. The support pads lie in a plane substantially parallel to the base. Upper and lower tie plates extend between the four posts to define a perimeter around the stillage. Internal partition plates are provided to form a plurality of compartments for receiving the drums, the inner ends of the partition plates being attached to a central ring. The stillages can be arranged in a free-standing stack with the base of an upper stillage resting on the support pads of a stillage beneath it. Such a stack is able to withstand loads resulting from seismic events.Type: GrantFiled: January 13, 1997Date of Patent: November 3, 1998Assignee: British Nuclear Fuels plc.Inventors: Raymond Victor Evans, David Stephen Hayward

Patent number: 4815571Abstract: An automatic brake adjuster has a strut composed of two parts between which there is a non-reversible threaded connection, relative rotation between the parts to vary the strut length being controlled by a clutch ring urged by a spring into clutching engagement with the housing. In order to prevent unwanted de-adjustment, the clutch ring forms a uni-directional locking connection with a housing by means of ratchet teeth on the external periphery of the ring and a pawl mounted in the housing.Type: GrantFiled: July 16, 1986Date of Patent: March 28, 1989Assignee: Lucas Industries public limited companyInventors: Hugh G. Margetts, Michael J. England, Stephen Hayward
