International Business Machines Corporation - Armonk NY

International Classification:

G06F 15177

US Classification:

713 2, 713 1, 714 15

Abstract:

The invention relates to a computer in which an image of the operating system is maintained in a secondary memory. This memory is either powered from a source independent of the main memory, or is non-volatile in nature. When the computer is reinitialized, the loader software that normally builds the operating system from components instead checks the secondary memory for the presence of an operating system image. If such an image is detected, the loader transfers the image from the secondary memory to the primary memory and transfers control of the computing system to the image of the operating system now in the primary memory. If no image is detected, the loader operates in a standard fashion. Additionally, a complete system image may be stored in the secondary memory. This would include the contents of the primary memory, the contents of the virtual memory, and the system state.

International Classification:

E21B 41/00
E21B 33/06

US Classification:

166 854

Abstract:

An apparatus for engaging and moving a ram block. In some embodiments, the apparatus, or ram block changer, includes a support bracket coupled to a blowout preventer and an articulated arm releasably coupled to the ram block. The ram block changer may further include a pivot coupling assembly having a first axis of rotation. The pivot coupling assembly extends through the support bracket and the articulated arm, wherein the articulated arm is rotatable about the first axis of rotation relative to the support bracket. The articulated aim may include a first member receiving the pivot coupling assembly therethrough, a second member coupled to the ram block, and a second pivot coupling assembly having a second axis of rotation spaced apart from the first axis of rotation and extending through the first and second members. The second member is rotatable about the second axis of rotation relative to the first member.
