摘要:
A portable apparatus for detecting latent fingerprints that discharges a vapor of a cyanoacrylate-containing solution. The apparatus comprises a reservoir for holding a liquid solution comprising cyanoacrylate, a valve for controlling the release of the solution through a capillary flow passage, and a power supply for heating the capillary flow passage and vaporizing the solution. When cyanoacrylate vapor contacts latent fingerprints, the fingerprints are rendered visible.

An air freshening device includes a liquid supply operable to supply liquid fragrance material, a wick in contact with the liquid supply, a conductive mesh material operable to retain the liquid material in interstices thereof, and a power supply operable to apply voltage across the mesh material so as to heat the mesh material and the liquid fragrance material contained in interstices of the mesh material to a temperature sufficient to vaporize the liquid. The air freshening device is operable to substantially prevent deposition of the vaporized liquid material.

A respiratory humidification system having a capillary passage in communication with a ventilator, the ventilator adapted to deliver an air stream, a heater operable to at least partially vaporize water in the capillary passage, a pumping unit adapted to supply water to the capillary passage, wherein the water upon heating is at least partially vaporized to form an aerosol stream. The aerosol stream is combined with the air stream to form a humidified air stream.

An aerosol generator includes a flow passage having an inlet and an outlet, a heater arranged relative to the flow passage for heating the flow passage, a source of material to be volatilized in communication with the inlet of the flow passage, a valve to open and close communication between the source of material and the inlet of the flow passage, and a pressurization arrangement for causing material in the source of material to be introduced into the flow passage when the valve is in an open position. The aerosol generator further includes a source of power for operating the heater and the valve, and a control device for controlling supply of power from the source of power to the heater and the valve. A metering device in an inhaler includes a pressurized source of medicated fluid and a metering chamber configured to deliver a predetermined volume of fluid to a heated flow passage in the inhaler. The metering chamber can be part of a rotary valve having a bore and a displacement member moveable within the bore from a first position where the fluid is loaded into the bore to a second position where the predetermined volume is ejected out of the bore. Another metering chamber has an elastic portion of a delivery passage in fluid communication with the pressurized source of liquid and the elastic portion of the delivery passage is deformed to eject the predetermined volume.

A fluid vaporizing device useful for vaporizing fluid into an aerosol and includes first and second capillary tubes connected electrically in series by providing separate electrodes at the inlet ends of each capillary tube, and connecting the outlet ends of the capillary tubes by an electrical connection that connects the outlet ends both electrically and thermally. The capillary tubes are heated by the flow of electricity therethrough, and liquid flowing through the tubes is vaporized. The outlet ends of the capillary tubes are easily maintained at a temperature for optimizing aerosol generation since there is minimal heat loss through the connection connecting the outlet ends.

A variable dilution cigarette, of the type having a filter with two relatively rotatable segments having slits in the plug wrapping and the tipping paper which rotate in and out of rotational registry to vary the dilution level, is provided which is insensitive to slight longitudinal misalignment of the slits. An array of longitudinal depressions is formed in one segment of the filter plug centered on the slit in the plug wrapping and ending short of both ends of the filter segment containing the slit. The depressions act as a plenum allowing the longitudinal flow of air between the slit in the tipping paper and the slit in the plug wrapping in case of longitudinal misalignment arising during use, but do not allow circumferential air flow when the slits are intentionally deregistered by relative rotation of the filter segments. Because the depressions do not reach the ends of the filter segment containing the slit, they do not allow any unwanted air into the filter.

A rheometer of the extrusion plastometer type is provided with means for forcibly mechanically mixing the material to be tested within the chamber of the rheometer. The rheometer preferably includes a pair of telescopically arranged pistons which can be selectively coupled and uncoupled from one another so that one of them can serve as a mixing device. The pistons are coupled for unitary movement when discharging the material being tested.

摘要:
A disposable aerosol generator for use with an inhaler device which includes a heater adapted to volatilize fluid stored in the disposable aerosol generator and method of using the inhaler. The disposable body includes a sealed chamber and an outlet, the chamber being located between first and second layers of material. The chamber holds a predetermined volume of a fluid which is expelled through the outlet when the fluid in the chamber is volatilized by the heater. The disposable body can include a series of spaced apart aerosol generators, each of which can be advanced to a release position at which the heater can heat one of the fluid containing chambers. Prior to heating the fluid, the outlet can be formed by severing the first and/or second layer with a piercing element and the volatilized fluid can be expelled from the outlet into a passage of a dispensing member.
