Patent number: 11668896Abstract: According to one implementation a mount pad is provided that includes a plurality of arcuate flexure members disposed between and connected to top and bottom plates. According to some implementations a majority or all of the arcuate flexure members have a semi-circular cross-section and are arranged to form a plurality of radially spaced-apart concentric rings. Concave surfaces of the arcuate flexure members face radially inward toward a center of the concentric rings. Circumferential adjacent arcuate flexure members in each of the concentric rings are circumferentially spaced apart from one another so that a gap exists between them. According to some implementations the mount pad further includes a coupling unit prolonging from one of the top and bottom plates, the coupling unit facilitating a connection of the mount pad to a support structure. According to some implementations the mount pad is a monolithic structure.Type: GrantFiled: March 11, 2021Date of Patent: June 6, 2023Assignee: EAGLE TECHNOLOGY, INC.Inventors: Sean A. Brennan, Matthew John East

Patent number: 7916880Abstract: An inertial force transducer having an operative frequency range comprises a resonant element having a frequency distribution of modes in the operative frequency range of the transducer and a coupler for mounting the resonant element to a site to which force is to be applied. The resonant element is a piezoelectric device comprising a layer of piezoelectric material and a substrate layer on the layer of piezoelectric material. The substrate layer has a region extending beyond the piezoelectric layer, with the coupler mounted to the extended region whereby the low frequency performance of the transducer is extended.Type: GrantFiled: June 15, 2005Date of Patent: March 29, 2011Assignee: New Transducers LimitedInventors: Mark Starnes, Steven Mark Hoyle, James John East, Neil Simon Owen

Patent number: 7475598Abstract: An electromechanical force transducer comprises at least two adjacent resonant elements and a damping layer coupled between their adjacent faces. The damping layer is selected so that the output is increased in the region of internal cancellation in the transducer. The adjacent resonant elements are beam-like and have substantially the same length. The resonant elements may be supported on a stub of low rotational stiffness whereby the fundamental resonance of the transducer becomes less dependent on bending motion of the transducer and more rigid body-like. The transducer may also include a member for increasing the rotational impedance of the transducer.Type: GrantFiled: March 10, 2006Date of Patent: January 13, 2009Assignee: New Transducers LimitedInventors: Mark William Starnes, James John East, Neil Simon Owen, Steven Mark Hoyle

Publication number: 20080242663Abstract: The invention concerns compounds of Formula I, or a pharmaceutically acceptable salt thereof, where R1, n, R2, R3, and R4 are as defined in the description. The present invention also relates to processes for the preparation of such compounds, pharmaceutical compositions containing them and their use in the manufacture of a medicament for use as an antiproliferative agent in the prevention or treatment of tumours or other proliferative conditions which are sensitive to the inhibition of EphB4 kinases.Type: ApplicationFiled: February 28, 2008Publication date: October 2, 2008Applicant: ASTRAZENECA ABInventors: Susan Elizabeth Ashton, Darren Anthony Edward Cross, Simon John East, Jason Grant Kettle, Mark Andrew Pearson, Stephen Robert Wedge, Bernard Christophe Barlaam, Richard Ducray, Stuart Charles Purkiss

Patent number: 4794777Abstract: A rotary wheel member for use in a rotary, friction type, continuous extrusion apparatus is produced by(a) producing a rotary wheel having formed in its cylindrical peripheral portion a continuous groove, and secured in that groove for movement with the wheel a solid annular metal mass;(b) rotating the wheel about its rotary axis; and(c) applying to the periphery of the annular metal mass a tool of predetermined end shape, and progressively advancing the tool in a radial direction as the wheel continues to rotate, thus machining in the peripheral portion of the annular metal mass a working groove of predetermined transverse cross section.Type: GrantFiled: June 6, 1986Date of Patent: January 3, 1989Assignee: Metal Box Public Limited CompanyInventors: John East, Ian Maxwell

Patent number: 4732551Abstract: A continuous extrusion machine in which feedstock in particulate or comminuted form is admitted to a peripheral groove formed in a rotating wheel member, is enclosed in that groove by a cooperating shoe member, is frictionally dragged along the arcuate passageway formed by said groove and a projecting portion of said shoe member towards an abutment member carried by said shoe member, and is continuously extruded as a metal product through a die orifice disposed at the downstream end of that passageway. A cooling device is provided downstream of the abutment member.Type: GrantFiled: February 11, 1986Date of Patent: March 22, 1988Assignee: Metal Box Public Limited CompanyInventors: John East, Ian Maxwell

Patent number: 4610725Abstract: A continuous extrusion machine, in which feedstock is admitted (at 50) to a peripheral groove (12) in a rotating wheel (10), is enclosed in that groove by a cooperating shoe (24), and is frictionally dragged along an arcuate passageway (48) formed by said groove and a projecting portion (30) of said shoe towards an abutment (36) carried by the shoe. The abutment tip and adjacent wheel parts disposed downstream of the abutment are cooled directly by a jet of cooling fluid issuing from a nozzle (64) carried downstream on the shoe. An annular band (FIG. 2, 74) of a good thermally-conductive metal embedded concentrically in the wheel enhances the cooling obtained. The extrusion apparatus yields a metal product (FIG.Type: GrantFiled: January 27, 1984Date of Patent: September 9, 1986Inventors: John East, Ian Maxwell

Patent number: 4604880Abstract: A continuous extrusion product issuing from a continuous extrusion apparatus is threaded through a treatment die (to change its cross-section) and is continuously drawn therethrough by a tensioning device controlled by a system which (a) senses the temperature of the product as it leaves the extrusion apparatus, (b) converts (in a function generator) a temperature signal so produced into a tension reference signal, (c) compares a tension feedback signal (derived from a sensor adjacent the extrusion apparatus) with that tension reference signal, and (d) controls the tensioning device in accordance with the difference of the tension reference and feedback signals so as to prevent the sensed tension in the product (extending between the extrusion apparatus and the treatment die) from exceeding a safe value which is less than the yield stress tension of that product at the sensed temperature.Type: GrantFiled: January 27, 1984Date of Patent: August 12, 1986Assignee: Metal Box Public Limited CompanyInventors: John East, Ian Maxwell
