IPC: B29D99/00
Filed: 2003-10-08
Abstract: A prosthetic socket casting device includes a base (12) with a forward side from which an expandable bladder (34) surrounding a central casting area (32 ) extends. The bladder includes a plurality of inner expandable chambers (42, 44) that generally extend along the length of the bladder interior and peripherally surround the central casting area. The inner walls of the chambers are formed of a pliable, fluid impermeable relatively thin sheet material that is distendable upon pressurization of the chamber volumes. The bladder further includes an outer covering or wall (36) formed of a material or construction that limits distention of the bladder outwardly. The chamber s may be expanded to constrict the central casting area in which a residuum having a settable prosthetic socket material thereon may be placed for moldi ng and curing under pressure. The multiple expandable chambers create a desirab le pressure distribution circumferentially around the central casting area.</SD OAB>

IPC: E21B47/04
Filed: 2005-08-23
Abstract: A method for registration and correction of downhole core depth information using digital core images. Digital core images are employed during depth registration, with top and base depths for a selected interval being determined by field data and a digital ruler which calculates an actual interval length based on the digital core image. Correction of the top and base depths is enabled by side- by-side display of the digital core image interval and corresponding well logging data, which displayed information can be manipulated by a user to provide more accurate depth information. The method further allows for shale volume calculations and facies interpretation, again employing the digital core images.
