Mold vent

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.

Convection blood warming system with disposable flattened tube envelope incorporating paperboard "needle" for inserting envelope between heating plates and employing active and passive insulation of outlet flow path to provide normothermic fluid at zero to 600 milliliters per minute

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.

Dual stage hybrid inflator

An inflator for an airbag has a cylindrical housing forming a pressure vessel for storing inert gas within a first end portion; a second end portion forming a separate combustion chamber, and an intermediate diffusion portion interposed between the first and second end portions for exhausting gases from the inflator into an airbag. The inflator has a first gas generator subassembly disposed within the first end portion and in communication with the stored inert gas. A second gas generator subassembly has a combustion chamber which is disposed within the second end portion and isolated from the inert gas by one or more rupturable sealing disks. The actuation of the inflator can be accomplished such that one or both of the gas generators can be ignited. The ignition can be simultaneously or sequential permitting either very rapid full filling of the airbag or slower prolonged filling.

Loudspeaker and alarm with luminous element

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.

Seal positioning assembly

An assembly structured to selectively orient a seal between an open position and a closed position. 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.
