摘要:
A sheet-like material such as a paper web or fabric web is treated with a fluid, for example, hot air or liquid dye. The material is carried by a permeable felt wire on which it is subjected to both pressure and direct fluid flow from a movable nozzle element. The nozzle element includes an endless support member driven by a pair of rollers and an outer flexible, chambered belt or sheet. The chambers of the flexible belt are provided with inlets through which the treating fluid, under pressure, is delivered thereto. The chambers are further provided with outlets or openings which allow the treating fluid to pass from the chambers. A porous sheet or belt is placed and secured around the flexible, chambered belt. In operation the sheet-like material passes through the apparatus on the permeable wire with the nozzle element moving in unison therewith. The treating fluid passes from the chambered belt, through the porous sheet into the material, with the pressure from the treating fluid maintaining the flexible belt, the porous sheet and material in a substantially sealed relation throughout the apparatus.

A method for cleaning a cooking apparatus having heating means and support means to support article means to be affected by the output of said heating means. The method comprising the steps of disposing electrode means to be carried by the cooking apparatus in electrically spaced relation to the article means, and imposing an electrical potential differential between said article means and said electrode means to tend to cause soiling particles of said article means to move toward said electrode means and be collected thereby during the heating thereof by the heating means to tend to prevent soilage of said cooking apparatus.

THIS DISCLOSURE RELATES TO A NOZZLE CONSTRUCTION FOR A VACUUM CLEANING APPARATUS OR THE LIKE FOR APPLYING A SUCTION TO A SURFACE TO BE CLEANED THEREBY, THE NOZZLE CONSTRUCTION COMPRISING A SUPPORT MEANS HAVING OPENING MEANS THEREIN PROVIDED WITH AN OUTLET TO BE INTERCONNECTED TO A VACUUM PUMP MEANS AND AN INLET TO BE DISPOSED ADJACENT TO A SURFACE MEANS TO BE CLEANED. A FLEXIBLE WALL SURROUNDS THE INLET SO AS TO HAVE ONE SIDE THEREOF ENGAGED AGAINST THE SURFACE MEANS AROUND SAID INLET TO SUBSTANTIALLY SEAL THE INLET OF THE SUPPORT MEANS TO THE SURFACE MEANS. THE FLEXIBLE WALL IS SO CONSTRUCTED AND ARRANGED THAT A PRESSURE DIFFERENTIAL ACTING ACROSS THE SAME RESULTING FROM THE VACUUM PUMP MEANS DRAWING FLUID FROM THE SURFACE MEANS INTO THE INLET AND OUT THROUGH THE OUTLET OF THE OPENING MEANS CASES THE FLEXIBLE WALL TO BE URGED TOWARD THE SURFACE MEANS TO SUBSTANTIALLY SEAL AGAINST THE SURFACE MEANS AROUND THE INLET AND SUBSTANTIALLY CONFORM TO THE CONTOUR OF THE SURFACE MEANS OUTBOARD OF THE INLET.

A cooking apparatus having an oven, heating means for heating said oven, and support means to support article means in said oven to be effected by the output of the heating means. Electrode means carried by the apparatus and being disposed in the oven, said electrode means being in electrically spaced relation to the article means. A potential differential imposed between the article means and the electrode means to tend to cause soiling particles of the article means to move toward the electrode means during the heating thereof by the heating means to tend to prevent soilage of the cooking apparatus. Means for creating air movement in said oven to direct the soiling particles toward the electrode means and means can be provided to ionize such soiling particles so that the same are more readily attracted by the electrode means.

SUPPORTING MEANS RECEIVING SHEET-LIKE MATERIAL AND CONVEYING THE SAME IN SUBSTANTIALLY FLAT FORM AND MOVABLE NOZZLE MEANS HAVING AN END MEANS PROVIDED WITH OPENING MEANS AND ENGAGING AGAINST THE MATERIAL FOR A PREDETERMINED SUBSTANTIALLY STRAIGHT LINE LENGTH OF TRAVEL THEREWITH, THE NOZZLE MEANS COMPRISING A FLEXIBLE SHEET MEANS AT LEAST PARTIALLY SURROUNDING THE OPENING MEANS AND DEFINING THE END MEANS THEREOF AND PROVIDING A FLUID FLOW BETWEEN THE OPENING MEANS OF THE NOZZLE MEANS AND THE SECTION OF MATERIAL ALIGNED BETWEEN THAT OPENING MEANS AND THE SUPPORTING MEANS TO TREAT THAT SECTION OF MATERIAL WITH FLUID. MEANS ARE PROVIDED FOR CAUSING THE END MEANS TO BE DISPOSED IN SUBSTANTIALLY SEALED RELATION WITH THE SECTION OF MATERIAL ENGAGED THEREBY BY CREATING A PRESSURE DIFFERENTIAL ACROSS THE SHEET MEANS TO CAUSE ONE SIDE THEREOF TO PRESS AGAINST THE MATERIAL ON THE SUPPORTING MEANS.
摘要:
In air-through dryers for wet sheet-like material, such as paper, textiles, etc., the moist sheet-like material is subjected to an air pressure differential across the same so that heated or unheated air is caused to be engaged against one side of the sheet-like material and pass therethrough to the other side thereof to remove moisture from such sheet-like material as the air passes therethrough, such moisture being removed by a pushing out of the moisture by the air and/or by air entrainment. A belt means of this invention comprising a perforated flexible wall carrying felt fabric or other similar material on one side thereof is utilized in a manner to engage against the moist sheet-like material to compress the same during the passage of air through the perforated flexible wall and through the moist sheet-like material to assist in the water removal thereof by tending to cause the retained moisture of the sheet-like material to continuously fill the voids thereof and be more readily swept away by the air flow than when no compressing of the moist sheetlike material takes place.
