摘要:
A cephalad prosthesis (330) for replacing all or a portion of a cephalad portion of a natural facet joint on a vertebral body is described. The prosthesis comprises: a prosthesis body (310) for accommodating fixation to the vertebral body at or near a pedicle (14) and without support by a lamina, and an artificial cephalad facet joint structure carried by the prosthesis body which is adapted and configured to replace all or a portion of a cephalad portion of a natural facet joint.

The invention provides a heat transfer composition comprising trans- 1,3,3,3-tetrafluoropropene (R-1234ze(E)), carbon dioxide. (R-744) and a third component selected from difluoromethane (R-32), 1, 1 -difluoroethane (R- 15.2a), fluoroethane (R-161), 1,1,1,2-tetrafluoroethane (R-134a), propylene, propane and mixtures thereof. The compositions are desgined to give higher flammable limit, higher ignition energy, and/or lower flame velocity. The compositions may be used to partially replace heat transfer agents with higher global warming potential such as refrigerants, heating agents, cooling agents, or foam blowing agents.
摘要:
An apparatus and method is provided for single transfer insert placement. The apparatus receives continuous web material and cuts a discrete section or pad from the web. The pad is then supported on a single transfer surface. The single transfer surface then may spin the supported pad to a desired angle and provide the pad to a receiving surface at a desired interval.
摘要:
The invention provides a heat transfer composition consisting essentially of from about 60 to about 85% by weight of trans-1,3,3,3-tetrafluoropropene (R-1234ze(E)) and from about 15 to about 40% by weight of fluoroethane (R-161). The invention also provides a heat transfer composition comprising R-1234ze(E), R-161 and 1,1,1,2-tetrafluoroethane (R-134a).
摘要:
Bicarbonate containing solutions for use during medical treatment are provided. The bicarbonate containing solution of the present invention includes at least two separate components including a bicarbonate concentrate and an electrolyte concentrate which can be readily and sterilely mixed to form a ready-to-use formulation for patient administration, particularly as applied to the treatment of acute renal failure associated with critically ill patients in an intensive care setting.
