Publication number: 20210332676Abstract: An apparatus and method according to which a perforating gun includes a volume fill body. The volume fill body is positioned in the space between a charge tube and a carrier tube. The fill body occupies at least part, and sometimes all, of the free volume space between the charge tube and carrier tube thereby reducing the free volume space. In certain downhole applications, large free volume space can lead to significant reductions in wellbore pressure, causing dynamic underbalance, which is undesirable. The presence of the volume fill body prevents, or at least reduces, dynamic underbalance and its effects. Also, the volume fill body aligns the charge tube with the carrier tube, further assisting perforation.Type: ApplicationFiled: July 8, 2021Publication date: October 28, 2021Inventors: Brenden Michael Grove, Richard Ellis Robey, Christopher C. Hoelscher

Patent number: 11141725Abstract: A hematology test slide has the same or similar dimensions as a chemical reagent test slide and an immunoassay test slide so that it may be used with these other slides on a single clinical instrument. The hematology slide includes, in order from top to bottom, a slide housing having a top housing member, a top cover slip, a U-shaped, transfer tape spacer, a bottom cover slip, a base gasket and a base plate. The U-shaped spacer has a curved end portion which defines a sample deposit area, where a blood sample is pipetted thereon, and a pair of straight, parallel, spaced apart legs extending from the curved end portion. The legs define a read area. A blood sample deposited on the hematology slide at the sample deposit area will flow by capillary action to the read area, where optical measurements are made on the sample.Type: GrantFiled: October 21, 2016Date of Patent: October 12, 2021Assignee: IDEXX Laboratories, Inc.Inventors: Garland Christian Misener, Richard Ellis Holt, Keith Nassif

Patent number: 11084311Abstract: A transferable receiver material is provided that includes a polymer film assembly comprising inorganic particles having a first dimension smaller than 100 nanometers and an orthogonal, second dimension larger than 100 nanometers. The polymer film assembly can be coupled with a carrier film and the polymer film assembly can be configured to separate from the carrier film and couple with a target object surface along a defined edge upon application of heat. Optionally, the polymer film assembly includes a holographic image configured to be transferred to a target object surface upon application of heat. The polymer film assembly can be configured to receive one or more dyes, pigments, inks, special effect materials, or special effect metals for thermally transfer onto a target object. After transfer onto a target object, images transferred by the material are visible through the polymer film assembly.Type: GrantFiled: February 25, 2019Date of Patent: August 10, 2021Assignee: Illinois Tool Works Inc.Inventors: Morven McAlpine, Richard Ellis

Publication number: 20210161496Abstract: Disclosed is a system and method for a system and method for an image processing-based approach has been developed for in vivo quantification of tissue and bodyfluid kinematics when certain human movements, physical loads and physiological stresses are experienced. Due to the absence of artificial or physical markers in those tissues or fluids during typical imaging (ultrasound, CT-scan or MRI), a virtual marker displacement and deformation scheme has been developed to measure movement and strain of both tissues and body fluids.Type: ApplicationFiled: September 6, 2018Publication date: June 3, 2021Applicant: TEXAS TECH UNIVERSITY SYSTEMInventors: Suhas Pol, Kerry K.

Patent number: 11002119Abstract: A method and apparatus according to which a perforating gun includes a first detonation train and a second detonation train. The first detonation train is detonable to perforate a wellbore proximate a subterranean formation. The first detonation train includes a first detonating fuse and a perforating charge ballistically connected to the first detonating fuse. The second detonation train is detonable to increase an internal energy of the perforating gun after detonation of at least a portion of the first detonation train. The second detonation train includes a second detonating fuse ballistically connected to the first detonating fuse. In some embodiments, increasing the internal energy of the perforating gun after detonating the at least a portion of the first detonation train decreases and/or delays pressure drawdown within the wellbore.Type: GrantFiled: September 12, 2019Date of Patent: May 11, 2021Assignee: Halliburton Energy Services, Inc.Inventors: Richard Ellis Robey, Jason Paul Metzger, Brenden Michael Grove
