Abstract: Filter assemblies, such as ceramic or super alloy filter tubes, for combustible gases laden with particles, are safely cleaned by providing a back pressure pulse of a clean combustible gas. The clean combustible gas, such as methane, ethane, propane, or butane, and may either be stored in an accumulator or tank as gas, or may be stored in liquid form and flashed into a gas before use. The pulsing gas may pass through a venturi, intermittent or periodic control of the valve to supply the back pressure gas through the venturi being provided. The cleaned combustible gas mixes with the clean combustible gas and passes through the filter assembly to a use station, such as a combustor where the gases are burned.

Said extraction means include extraction openings (4, 16, 19, 50, 51) arranged on both sides of the interface in normal operation; the sum of the throughflow sections of said openings, estimated from a reference position on at least a portion of a vertical axis, varies as a function of the slope, considered on said axis and for said portion, said portion extending during normal operation on both sides of said interface.

Abstract: An electrical control assembly for a humidistat controlled humidifier of the type having a base connected to the furnace ductwork and a cover removably connected to the base includes a control circuit board having a primary circuit for operation of the fan and a secondary circuit for operation of the humidistat and solenoid valve. A separable electrical connector disposed within the humidifier has a connected state in which power is supplied to the humidistat and a solenoid valve and a disconnected state in which power for the humidistat and solenoid valve is cut off. The electrical connector is fixedly mounted in the base and cover of the humidifier and is positioned so that the electrical connection is automatically made when the cover is connected to the base.

Abstract: The invention is directed to an adjustment safeguard for an adjusting screw rotatably held in a housing. The adjusting screw has a head which projects outside of the housing and a cap is mounted on the head of the adjusting screw so as to be accessible to an operator for imparting a rotational movement thereto. The cap has an appendage formed thereon and stops are provided which coact with the appendage to delimit the rotational range through which the adjusting screw can be rotated. A sleeve is disposed in surrounding relationship to the cap and is connected thereto. The cap is disposed almost entirely within the sleeve so that an operator cannot reach the cap for levering the latter off the adjusting screw without causing permanent visible damage to the safeguard. Accordingly, an effective tampering with the adjusting screw for obtaining a setting outside of the permitted adjusting range is effectively prevented since such a tampering will leave permanent visible damage.

Abstract: A multi-ply expandable filter media formed of obliquely oriented honeycomb organized into a ply or run having expandable honeycomb cells with one run oriented at, preferably an acute angle, of 30.degree. to 60.degree. relative to the cells of an adjacent run. Preferably, the respective plys or runs are arranged in relative parallel planes defining a planar space therebetween. There is provided means for collapsing the filter media into a closed compressed, transportable state, and when ready for use as a filter media, to allow the same to be expanded and pulled open and to be constrained in an preselected, open, expanded position so that the cross-sectional area of each cell is thereby substantially increased. In this manner, the juxtaposed, open plys allow directional change for airflow flowing through the filter media, encouraging deposits of air-borne material to become attached to the wall surfaces of the family of cells of each run or ply.
