Patent number: 9957771Abstract: A status assembly to provide visual and electronic indication of the position (open, closed, in-between) of the ram of a ram-type blowout preventer (BOP). The assembly is capable of coupling with a hydraulic motor that can be used to open and close the ram locks. The status assembly includes a rotatable element protruding from the BOP, a gear rotatable by the rotatable element, and an indicator that indicates the rotation position of the rotatable element and thus the linear position of the BOP ram. Some embodiments can also include a sensor that outputs an electronic signal to the system operator and can be incorporated into the main display for the BOP control system. This device is able to give immediate feedback to operators and to indicate whether each ram has achieved its intended travel.Type: GrantFiled: February 10, 2015Date of Patent: May 1, 2018Assignee: CAMERON INTERNATIONAL CORPORATIONInventors: Andrew Jaffrey, Gerrit M. Kroesen, John Mangan

Publication number: 20160298409Abstract: A blowout preventer includes a housing, comprising a longitudinal bore extending therethrough and a cavity intersecting the bore, and pair of opposing shear rams configured to shear a tubular located in the longitudinal bore. The opposing shear rams can be moved radially into and out of the longitudinal bore by connecting rods coupled to the shear rams. The connecting rods may be coupled to the shear rams via intermediate connecting assemblies which may include a split-flange connector comprising multiple sections. The shear rams and/or the connecting rods may be constructed of a high-strength heat treatable, low alloy steel, such as AISI 4340 steel. The shear rams are constructed of a single material having a higher hardness than that of the tubular product.Type: ApplicationFiled: March 31, 2016Publication date: October 13, 2016Applicant: Cameron International CorporationInventors: Gerrit M. Kroesen, Melvyn F. Whitby, Johnny Everett Jurena

Patent number: 9095428Abstract: An artificial heart with a centrifugal pump is disclosed. In one embodiment, the artificial heart includes an impeller disposed in a housing. The impeller is configured to rotate to circulate blood through the housing. The impeller may include a set of blades on a first side of the impeller and a set of vanes on a second side opposite the first. The blades on the first side and the vanes on the second side allow blood circulation from both the first and the second sides of the impeller. The artificial heart may also or instead include a diffuser with adjustable vanes that enable variation in the output characteristics of the artificial heart pump. Various other artificial hearts, pumps, systems, and methods, including control systems and methods, are also disclosed.Type: GrantFiled: June 7, 2013Date of Patent: August 4, 2015Assignee: Cameron International CorporationInventors: Omar M. Kabir, Ronald W. Webb, Mark A. Patterson, Gerrit M. Kroesen, John C. Etcheverry, Daniel B. Baxter, Robert Small
