Abstract: An apparatus for continuously transporting and dipping patterns in a process wherein patterns of a desired shape are dipped in and coated with a liquid that subsequently forms a thin membrane thereon. The apparatus includes an endless roller chain assembly that carries a number of pattern carrier assemblies through a linear dipping span. Each pattern carrier assembly includes a vertical track attached to the roller chain assembly and a carrier arm slidably connected to the track for vertical movement therein between a raised position and a lowered position. A pattern support bar is connected to the carrier arm and extends perpendicular to the dipping span of the roller chain assembly. Two or more parallel rows of patterns are suspended from the pattern support bar with their maximum width dimension extending perpendicular to the bar and with the patterns of each row being closely spaced to the patterns of the adjacent row so that at least two rows are transported simultaneously by the same carrier arm.

Abstract: A fluid filter of the bag type that has a rotatable agitator means mounted within the filter chamber.

Abstract: An inverse flow depth filter assembly includes an elongated, generally elliptical housing with gas inlet and egress means, and a bottom drain. A filter cartridge is suspended from the housing top so that an annular channel is created between the housing and the cartridge. The cartridge has passages at the top, leading to the egress means and an open bottom. Air enters the housing and is channeled downward through the annular channel until it reaches the cartridge bottom, quiets the turns upwardly through the filter. Heat exchange apparatus cools the down-flowing air and promotes condensation of the water. The heat exchange apparatus can include a plurality of fins fixed to the exterior of the housing to promote heat exchange with the surrounding atmosphere. Heat exchange fins disposed internally at the annular channel promote heat exchange between the flowing air and the housing. The fins increase the contact surface area for better heat exchange with the outside air.

Abstract: The disclosure herein describes an air-cleaning apparatus which comprises a frame support in the form of a rectangular hollow body including a first lateral wall having an inlet adapted for receiving exhaust and a second lateral wall opposite to the first lateral wall having an outlet for expelling cleaned exhaust; at least one filtering member removably inserted between the first and second lateral walls, which has a plurality of suitably dimensioned perforations formed therein, means for supplying a cleaning liquid, said means enabling said cleaning liquid to flow against said filtering member and spread over said perforations; and means for collecting said cleaning liquid. When a stream of the cleaning liquid is spread over the filtering member, a liquid film is effectively formed on the perforations therein, which will efficiently remove any pollutants existing in the exhaust so as to prevent air pollution from resulting therefrom.

A second valve in an outlet conduit connected to the reservoir may interrupt flow from the reservoir when vacuum is applied to the reservoir.

Abstract: An arrangement for generating an electric corona discharge in air having a corona electrode, a target electrode which is spaced from the corona electrode, and a d.c. voltage source, the respective terminals of which are connected to the corona electrode and the target electrode. The voltage of the voltage source and the construction of the corona electrode are such as to generate a corona discharge at the corona electrode. A conduit is provided for continuously removing the air present in the immediate vicinity of the corona electrode and dealing with the air thus removed in a manner to render innocuous physiologically harmful substances or irritants present in the air and generated by the corona discharge, such as primarily ozone and nitrogen oxides.

Abstract: A spray booth is provided with inexpensive, disposable pre-baffles which collect overspray thereon prior to the overspray reaching the filtering stages. The preferred disposable pre-baffles are made of paperboard and after being coated with overspray for a short period, e.g., one week, are easily detached and replaced. The paint on the disposable pre-baffles can be baked to convert the paint and the baffle from a hazardous to a non-hazardous waste. The pre-baffles may collect as much as 80% of the overspray, some of which may be collected and re-used, and reduces the amount of sludge, filter cleaning, chemicals used in the reservoir water, and the emissions. Thus, the overall savings easily overcome the expense of replacing the disposable pre-baffles.

Abstract: An emission control unit is mounted in the exhaust line of a fossil fuel internal combustion engine and includes a tubular housing in which a lime sleeve is received. The sleeve has an axial opening through which a corona wire extends. Exhaust gasses pass through the sleeve along the wire. Placing a charge on the wire drives pollutants in the exhaust laterally outwardly into the sleeve at a direction which is 90.degree. to the direction of exhaust travel. The sleeve chemically interacts with the pollutants and neutralizes them with little hazard to the environment.

Abstract: Particulates in the form of fine dust are removed from gas streams by impinging the particles on screens located in the path of the particles to result in the build up of a deposit on the mesh, until the deposits grow to a sufficient size that the combined effect of gravity and gas flow dislodges the deposits, which are collected.

Abstract: A distinctive method and apparatus for depositing a pattern of material, such as hot-melt adhesive, onto a substrate comprises a supplying mechanism for forming a first and at least a second substantially continuous stream of the selected material, and a gas-directing mechanism for forming a plurality of gas streams. The gas streams have selected velocities and are arranged to entrain the material streams to impart a swirling motion to each of the material streams as it moves toward the substrate. A transport mechanism moves the substrate relative to the supply mechanism along a selected machine direction. A regulating mechanism controls the supplying mechanism and gas-directing mechanism to direct the material stream in a selected path toward the substrate and deposit the material in adjacent semi-cycloidal patterns on the substrate while closely controlling a selected cross-directional positioning of one or more of the deposited patterns.

This will permit the end portions of the electrodes to be joined to the tubes of the tensioning frame by welding at two points whereas the corona points need not be appreciably spaced from the electrical center.

Abstract: A gas mixture separator having adsorbent (1) with pressure dependent adsorptivity includes a cylinder (2) and a piston (3) as a means of pressure modulation necessary for the adsorption and desorption of gas components to be separated. Ingredient gas to be separated is fed to the cylinder through an inlet valve and inlet (5) to flow into contact with the adsorbent (1) by pressure produced by the piston (3) moving toward top dead center in the cylinder (2). The unadsorbed gas component passes through the adsorbent and exits the cylinder through the outlet (4) and associated outlet valve. The adsorbed gas component is desorbed during depressurization of the cylinder (2) during the retraction stroke of the piston (3) and exits through the outlets (8, 6) therefore. Adsorbed gas is introduced into the cylinder (2) through an inlet (7) therefrom from an additional separator for recovery of energy therefrom.

Abstract: The invention is directed to a method of removing solids from a container. he method is for discharging sedimentated solids from a container which is inclined in the direction toward its outlet. The method is technically simple and prevents or minimizes the amount of secondary waste or the use of flushing liquid. This result is achieved by subjecting the residual liquid in the container to the action of pulsed compressed air which passes through a perforated pipe extending parallelly to the bottom of the container. A container apparatus for carrying out the method is also disclosed.

Abstract: Process for the separation and purification of oxygen and nitrogen is disclosed which utilizes solutions of oxygen carriers to selectively absorb oxygen from a gaseous stream, leaving nitrogen as a byproduct. In the process, an oxygen carrier capable of reversibly binding molecular oxygen is dissolved in a solvent solution, which absorbs oxygen from an oxygen-containing gaseous feed stream such as atmospheric air and desorbs oxygen to a gaseous product stream. The feed stream is maintained at a sufficiently high oxygen pressure to keep the oxygen carrier in its oxygenated form during absorption, while the product stream is maintained at a sufficiently low oxygen pressure to keep the carrier in its deoxygenated form during desorption.
