Under one aspect of the present invention, a liquefied gas pump assembly is coupleable to a source of liquefied gas. A cooling assembly is positioned generally adjacent to a pump module. The cooling assembly has a converging pump-head-receiving aperture, a fluid inlet line and a fluid outlet line in fluid communication with the source of liquefied gas and in fluid communication with the pump-head-receiving aperture. A pump head assembly is removably retained in the pump-head-receiving aperture so that a portion of the cooling assembly is between the pump head assembly and the pump module. The pump head assembly has a converging shape and being sized to engage the cooling assembly in a wedged configuration when the pump assembly is in an installed position in the cooling assembly. The pump head assembly has a fluid inlet pathway abutting in sealable engagement with the fluid inlet line of the cooling assembly. The pump head assembly also has a fluid outlet pathway abutting in sealable engagement with the fluid outlet line the cooling assembly, the pump head assembly being operably coupled to the pump driver of the pump module to provide a flow of the liquefied gas from the fluid inlet line, through the pump head assembly, and to the outlet line.
Systems And Methods For Ventilation In Proportion To Patient Effort

Assignee:
Covidien LP - Mansfield MA
International Classification:
F16K 31/02
US Classification:
12820423, 12820421
Abstract:
Various embodiments of the present disclosure provide systems, methods and devices for respiratory support. As one example, a ventilation system is disclosed that includes a computer readable medium including instructions executable by a processor to receive a measured pressure value and a net flow value. A patient effort value is calculated based on a relationship between patient effort, the measured pressure value and the net flow value. The instructions are further executable to calculate a gas delivery metric that varies as a function of the patient effort value. Gas is then caused to be delivered consistent with the gas delivery metric.

US Classification:
12820421, 12820418, 12820524
Abstract:
Various embodiments of the present invention provide systems, methods and devices for delivering a defined gas mixture to a recipient. For example, various embodiments of the present invention provide ventilators that include at least two gas sources, a gas outlet and a differential flow transfer element. The differential flow transfer element receives one component gas from one of the gas sources at a first flow rate, and another component gas from the other gas source at a second flow rate. The differential flow transfer element distributes a mixture that includes at least the aforementioned component gases at a third flow rate via the gas outlet. The third flow rate is less than the sum of the first flow rate and the second flow rate.

Auto-Loading Transport For Tape Cartridge With Tape Access Door And Belt Capstan Roller

Assignee:
Cipher Data Products, Inc. - San Diego CA
International Classification:
G11B 5008
US Classification:
360 965
Abstract:
A tape transport fits within the five and one-quarter inch form factor and has motor driven mechanisms for automatically loading a DC600-type cartridge endwise therein. The transport includes a frame dimensioned to fit within the form factor, and a front panel extending across a forward transvere end of the frame. The front panel has a slot dimensioned so that the cartridge can be endwise inserted through the slot onto a tray movably supported within the frame. A read/write head is mounted to the frame adjacent the tray for reciprocating the head along an axis perpendicular to a base plate of the cartridge. A capstan drive motor is also mounted to the frame adjacent the tray so that a capstan drive roller connected to its shaft can drive a belt capstan roller of the cartridge. Guides associated with the tray permit the same to be moved by a motor driven gear box to automatically carry the cartridge rearwardly and then laterally into engagement with the read/write head and the capstan drive roller. A door opener partially opens the tape access door of the cartridge as the cartridge moves rearwardly so that when the cartridge is thereafter moved laterally the head can engage the tape.
Multicolor Electrophotographic Development System With Detachable Liquid Developing Devices Rotatably Mounted

Assignee:
ColoRep, Inc. - Carlsbad CA
International Classification:
G03G 1510
US Classification:
355256
Abstract:
A liquid electrophotographic development system has a plurality of removable cartridges mounted on a rotatable support for selective engagement with an electrophotographic member to be developed. Each cartridge has a liquid developer reservoir and a flexible toner concentrate container from which concentrate is supplied to the developer in the reservoir as needed. A fluted roll pumps developer in a uniform manner from the reservoir to the electrophotographic member. After depletion of the toner concentrate and developer, any developer remaining in the cartridge can be pumped into the flexible container to prevent spillage on disposal of the cartridge. The cartridge housing has only one opening and minimum-size passages between the reservoir and the opening to inhibit evaporation of developer liquid.
