Title: Preemptive multi-tasking with cooperative groups of tasks
Inventor: D SOUZA DAVID
IPC: G06F9/48
Filed: 1994-09-02
Abstract: An operating system combines preemptive scheduling with cooperative or non-preemptive scheduling. In particular, tasks are divided into groups of interdependent tasks. Each group includes tasks that should not be run asynchronously relative to each other. The scheduler in the operating system provides each group with a time slot of processor time. The tasks within the group are cooperatively scheduled to exploit the time slot assigned to the group. Dependencies between modules and tasks are maintained to assure that no difficulties arise amongst preemptively scheduled groups.

Title: Hydraulic device for supplying a hydraulic driving unit
Inventor: HEHL KARL
IPC: F04B49/06
Filed: 1994-10-06
Abstract: ABSTRACT            HYDRAULIC DEVICE FOR SUPPLYING A HYDRAULIC DRIVING UNIT            In a hydraulic device a variable capacity pump adapted to record a differential pressure via a control valve is actuated in such a way that a constant operational pressure gradient is maintained. Since the variable capacity pump is driven by a rotary current motor, which is connected to a current source by a frequency converter and is regulable with regard to its speed, it is possible to control hydraulic consumers in an energy-saving manner at a reasonable price.

Title: Stabilized thermal-dye-bleach constructions
Inventor: HELLAND RANDALL H
IPC: G03C1/498
Filed: 1994-11-09
Abstract: Certain poly(lactic acid) and poly(glycolic acid) polymers or copolymers, and certain carbonates, lactones, lactates, lactylates, lactides, glycolates, glycolylates, and glycolides have been found to stabilize thermal-dye-bleach constructions containing a dye in association with a thermally-generated-bleaching agent.  Preferably, the thermally-generatated-bleaching agent is a thermal-carbanion-generating agent such as a quaternary ammonium salt of a phenylsulfonylacetic acid or a thermal-nucleophile-generating agent such as an ammonium salt of a phenylsulfonylacetic acid.  These materials have been found to be particularly effective when used in acutance and antihalation systems for photothermographic and photographic elements.

Abstract: An apparatus is pro-vided for controlling the ripen-ing of produce. The apparatus includes a chamber (10) having a ceiling (16) a floor (12) and a plurality of walls (18, 20). Posi-tioned in the chamber (10) is a support and position structure (32) to support two rows (34, 36) of palletized produce (24) and to space the palletized pro-duce (24) away from the walls (18, 20) to define a fluid circu-lation space around the palle-tized produce (24).

Each row (34, 36) of palletized produce (26) includes at least an upper (42) and a lower (38) tier with a vertical spacing therebetween. A flexi-ble sealing strip (64) is affixed to the support and position structure (32) to generally seal the vertical spacing between the tiers from the fluid circulation space. A fluid control mechanism (68, 70) is provided to exhaust fluid from the interstitial volume and to introduce a controlled fluid into the fluid circulation space to create a pressure differential between the interstitial volume and the circulation space to thereby force the controlled fluid to flow generally uniformly through the palletized produce (24).

Title: Gastrostomy catheter system
Inventor: MCNEELY GWYN F
IPC: A61M31/00
Filed: 1994-01-04
Abstract: This invention is a system and method for inserting a gastrostomy catheter (10) through a passageway formed through the abdominal and stomach walls (11, 12) of a patient. The gastrostomy catheter (10) is mounted onto a dilatation catheter (13) with a dilatation member such as an inelastic balloon (14) on the distal extremity thereof. An introducer needle is first advanced through the walls of the patient's abdomen and stomach (11, 12) into the interior of the stomach and then a guide wire is advanced through the inner lumen of the needle into the stomach interior. The gastrostomy catheter/dilatation catheter assembly (10, 13) is advanced over the guide wire until the balloon (14) on the dilatation catheter (13) is in proper position crossing both the abdominal and gastric walls (11, 12). Upon inflation of the balloon (14) on the dilatation catheter (13), the passageway is expanded enough so that the gastrostomy catheter (10) can be advanced therethrough to dispose the distal end of the gastrostomy catheter (10) within the interior of the stomach. The balloon (14) on the distal end of the gastrostomy catheter (10) is inflated so as to for an internal retention member.

Title: Apparatus for controlling molten metal flow in a tundish to enhance inclusion float out from a molten metal bath
Inventor: SCHMIDT MANFRED
IPC: B22D11/117
Filed: 1995-11-16
Abstract: Flow control apparatus for enhancing inclusion float out in a continuous caster tundish comprising a dam positioned downstream from an impact pad and an energy source positioned between the dam and the exit nozzle of the tundish. The dam receives an incoming flood of molten metal released from the impact pad and redirects the flood of molten metal into multiple sub-flow currents which carry entrained inclusions toward a slag cover on the surface of the molten metal bath to enhance inclusion float out. The energy source provides means to restore kinetic energy to the sub-flow currents and increase the number of passes below the slag cover, thereby further enhancing inclusion float out.
