Abstract: A fluid cartridge having a plastic fluid body, a bottom wall having a fluid supply opening therein. An insert is adhesively fastened to the bottom wall. The insert has a fluid supply slot therein corresponding to the fluid supply opening in the bottom wall, a die bond surface adjacent to the fluid supply slot for adhesively fastening an ejection head chip thereto, and a plurality of air vents adjacent to the die bond surface. The insert is a material selected from an epoxy molding compound and a ceramic material. An ejection head chip is adhesively fastened to the die bond surface of the insert.

Abstract: A copy utility creates a copy of source database objects that is transactionally consistent to a consistent point-in-time, and a recovery utility applies log records to the consistent copy to make a resulting image that is updated as of an identified point-in-time (i.e., the current time or a point-in-time after the copy was made). To effectively recover and apply the logs so that no previously in-flight transactions are lost, the copy utility registers a starting point indicating a point-in-time for logs to be applied to the copy and also registers a smallest lock size used to block access to target data when the copy was made. The recovery utility bases its recovery operations using the registered starting point and the smallest lock size when applying log records to the copy so as not to lose any previously in-flight transactions.

Abstract: A rudder blade means of the type designed to reduce the drag produced by rudder blades of conventional design. The novel design, having utility in any vessel that travels through a fluid medium and incorporates a substantially vertically aligned chamber formed internally of the rudder body. The chamber has a narrow, slot-like portion that is in open communication with the trailing edge of the rudder body, and an enlarged, bore-like portion remote from said trailing edge but in open communication with the innermost portion of said slot-like portion. In applications where the rudder body is mounted to a sea-going vessel, and wherein such rudder body has a submerged portion and an un-submerged portion, water enters the chamber, in a counterswirling pattern, through the slot-like portion, and is driven upwardly, by water pressure, through the bore-like portion and is expelled above the water line through the uppermost region of said slot-like portion of such chamber.
