A lamp or lighting device is disclosed for use in dispensing vapors over a sustained period. Vaporizable material is contained in minute capsules; and heat resulting from operation of the lamp causes a controlled release of vapors.

A sensor for gaseous and vaporous species is disclosed. The sensor comprises an electrically insulated substrate which contains small pores passing completely through it. Electrodes consisting of metallic or semiconductor material are deposited onto the top surface of the substrate. In a first embodiment of the invention, an electrolyte is placed on the top surface of the substrate in such a manner as to create a gas or vapor permeable electrolyte layer on top of the electrodes. In a second embo...

A condenser for vaporous materials, in which at least two pipes are assigned to one another in a series arrangement and are circumflowed by a cooling medium. A separation device is provided at the discharge port of every pipe. This separation device causes the residual vapor to separate from the condensation product. The separation devices are connected via collectors to a pair of collecting chambers from which the condensation product is withdrawn.

When microbial contamination is introduced into a room (20*) of an enclosure, such as a building, an HVAC system including supply ductwork (16) and a return ductwork (34) is decontaminated with hydrogen peroxide vapor. A decontamination controller (46) operates controllable baffles (22) at outlet registers (20), temporary controllable baffles (44) at inlet registers (30), and a blower system (10) to circulate hydrogen peroxide vapor from hydrogen peroxide vapor generators (42) through the ductwo...

Pump apparatus according to the present invention may comprise a pump body having a bore therein and a piston mounted within the bore so that the piston may be reciprocated within the bore between first and second positions. A sleeve seal assembly mounted to the pump body contacts the piston as the piston moves between the first and second positions. A piston seal assembly mounted to the piston contacts the bore in the pump body and is located on the piston so that the piston seal assembly does ...

High molecular weight components are separated from lower molecular weight components of a vaporous fluid stream. A first vaporous fluid feedstock is expanded. A second vaporous fluid feedstock is compressed. Said expanded and compressed streams are then passed in indirect heat exchange relationship to cool said compressed stream. The cooled compressed stream is then passed to a separation zone to separate the more volatile lower molecular weight components from the less volatile higher molecula...

Apparatus for dosing gaseous and/or vaporous substances An apparatus for dosing gaseous and/or vaporous substances, in particular for generating varying scents, includes a multitude of packaged storage containers (1) from which different gases and/or vapors are driven out by a carrier medium. On their inlet sides, the storage containers are connected to a common carrier medium manifold (13) via a shut-off device (4) assigned to each storage container that can be actuated, and on their outlet sid...

In a distillation column with vaporous sidestream removal, the vaporous product removed is condensed in a condenser. The vapor pipe provided for the removal of product opens into a dip tank of which the upper end is connected to the condenser while its lower end is connected to a discharge pump. Inert gas present in the condensate is returned to the column above the sidestream removal through an inert gas pipe arranged at the upper end of the condenser.

This invention relates to a process for remediating vaporous pollutants which comprises passing a vaporous stream containing one or more of pollutants through a bioreactor, the bioreactor comprising a plurality of biologically active bodies, the biologically active body comprising a macroporous substrate and one or more of microorganisms capable of remediating one or more of said pollutants, wherein the substrate is fabricated from a decomposition-resistant material. The present invention furthe...
