A vent, system and method for controlling flow of fluid into and out of a mold cavity. The vent has a plurality of passages that each have narrow oblong slot-shaped openings in the mold cavity and which each expand in size in a direction leading away from its opening. The vent preferably is an insert that comprises a grate with at least a plurality of vent slots. The grate preferably is formed of two halves with fingers that interleave to form the slots when assembled. The grate preferably is discharge machined from disc-shaped blanks cut from elongate stock made a material that preferably is non-porous and smooth. The grate can be mounted in a pocket in the mold cavity or carried by a movable pin. A system uses valving and a source of fluid and, if needed, a source of vacuum to help facilitate venting by drawing atmosphere out of the cavity during molding. The system can also be used to introduce fluid through a vent such as for foaming moldable material in the cavity. The system can also be used to introduce a heat transfer medium into the mold cavity. The system can also be used to accelerate venting during one part of a mold cycle and then introduce fluid into the cavity during the same cycle.

A thin, flat paperboard inserter or "needle" which is longer than the blood warmer heating plates is attached to the edge of the flattened tube envelope to enter the very narrow gap between the heating plates. The inserter is fed between the heating plates and advanced to emerge from the other end of the blood warmer where it is grasped and used to pull the envelope into operational position. A high air flow hydrophobic vent with check valve to prevent reverse flow is incorporated into the drip chamber to allow automatic priming and venting of air bubbles. A conductively heated and externally insulated drip chamber holder and a patient intravenous line that is passively insulated by a small annular air space extruded as part of the tube preserve heat in the warmed fluid, improving low flow rate performance. A reusable external heater may optionally be applied to the distal portion of the patient line to provide normothermic fluid to the patient down to essentially zero flow rate.

A loudspeaker has an alarm and a luminous element, these being an improvement upon exiting loudspeakers having luminous elements. The luminous element is an illuminating lamp. A radiative cooling fin is mounted near the illuminating lamp. The use of radiator cooling firework permits a larger power light to be selected as the luminous element. This makes the loudspeaker capable of functioning as a substitute light source within an area. Also, the assembly employs an alarm with the loudspeaker. The brighter light emitted by the illuminating lamp on each loudspeaker provides better illumination. The lamp may also flash according to pre-programmed directions for the purpose of indicating a path and thereby helping people to escape from danger. Further, where the external power source fails, the loudspeaker assembly has a built-in emergency power source, ensuring that the loudspeaker and the illuminating lamp can still work normally.

The assembly includes an expander structure disposable into a seal open or a seal closed orientation by being rotated or otherwise movable into and out of forced engagement with predetermined portions of the seal structure. The seal open orientation disposes the seal structure out of engagement with an instrument passing there through and may also facilitate a rapid venting of insufflation gas from an inflated body cavity, such as when the seal positioning assembly is used with a trocar assembly involved in the performance of laprascopic or like surgery. A biasing assembly may be connected to the seal structure to bias it in a normally closed position in the absence of an instrument disposed within the seal structure.

Fluid activatable adhesive compositions and activating fluid(s) for activating the adhesive composition are described herein. The adhesive compositions contain at least two polymers with different hydrophilicities. The hydrophilic polymer has quick tack when exposed to a hydrophilic solvent, such as water or other aqueous solvent, while the hydrophobic polymer provides strong adhesion to a paper or polymeric substrate. The adhesive composition may contain particulate fillers which enable fast exhaustion of the activation fluid out of the adhesive when applied to a substrate, thereby allowing the hydrophobic polymers of the adhesive composition to achieve strong adhesion of the liner-free label to the paper or polymeric substrate. The particulate fillers may also function as anti-blocking agents when liner-free label media are tightly wound in a roll. The adhesive compositions described herein may be used not only on paper, cardboard, and metal, but also on glass and plastics commonly used in commercial applications.
