Title: Adaptive error correction to improve for system memory reliability, availability, and serviceability (ras)
Inventor: KJERSTEN E CRISS
IPC: G11C29/00
Filed: 2021-11-17
Abstract: A memory subsystem includes memory devices with space dynamically allocated for improvement of reliability, availability, and serviceability (RAS) in the system. Error checking and correction (ECC) logic detects an error in all or a portion of a memory device. In response 5 to error detection, the system can dynamically perform one or more of: allocate active memory device space for sparing to spare a failed memory segment; write a poison pattern into a failed cacheline to mark it as failed; perform permanent fault detection (PFD) and adjust application of ECC based on PFD detection; or, spare only a portion of a device and leave another portion active, including adjusting ECC based on the spared portion. The error detection can be based 10 on bits of an ECC device, and error correction based on those bits and additional bits stored on the data devices.

Title: Oil rig escape chute assembly - inflates when extended from upper platform and is prevented from sliding sideways
IPC: A62B1/20
Filed: 1973-09-14
Abstract: The chute (10) is particularly for evacuating offshore oil drilling platforms in the event of fire, and can be inflated so as to extend from a high platform (11) to a lower surface (12). Flexible guide members (18) are attached to opposite sides of an extensible portion of the chute, and fixed to supports mounted on the platform to either side of the chute. These members prevent the chute sliding sideways in the extended position. The chute can hinge on the platform on a horizontal axis, the supports being so positioned that the guide members attached to them are situated at points along the horizontal axis. Thus they resist sideways movement as the chute swings up and down.

The sensible heat in the product gas is used at its maximum temp. to produce superheated steam at a pressure which may exceed the pressure in the gas generator. This steam may be used as dispersant or carrier gas for the fuel feed or as a temp. moderator.

IPC: B29C48/10
Filed: 1987-03-27
Abstract: Process and device for cooling a tubular sleeve produced by hot extrusion-blowing of a thermoplastic material through an annular die. In the process, a stream of primary air is flowed under pressure substantially parallel to and spaced from the tubular sleeve and reaches the tubular sleeve at a second stage. The stream of primary air induces a stream of secondary air which flows substantially parallel and proximate to the tubular sleeve at a first stage and whose flow is substantially laminar over most of its path. The device includes a first cylindrical sleeve member that, in combination with the tubular sleeve, defines a secondary air flow space. A second cyclindrical sleeve member and the first sleeve member define a primary air flow space therebetween. A cylindrical ring disposed proximate to the annular die directs air into the secondary air flow space. A source of pressurized air is in flow communication with the primary air flow space.
