Abstract: TITLE          PROCESS AND APPARATUS FOR REMOVAL OF IMPURITIES FROM LIQUIDS          ABSTRACT OF THE DISCLOSURE          A unit is disclosed for removal of impurities present in liquids such as waste water effluent.  The unit comprises a vessel containing a loose quantity of particulate treating material for absorption or reaction with the impurities in the liquid.  A wall of the unit has multiple small openings therein, each of the open-ings filled with a finely-divided, compacted, particulate filter material such as diatomaceous earth which is retained in the open-ings by one or more layers of a woven inert material such as nylon or polyester having mesh openings sufficiently small to prevent passage of the particulate filter material therethrough.  The woven material is secured over the outer surface of the openings in the wall of the vessel.  Means are mounted within the vessel to pro-gressively sweep over the inner surface of the wall just out of contact therewith and over the openings in which the particulate filter material is retained to remove impurities lodged thereon and prevent blinding of the filter material by such impurities.  The same means also acts to uniformly mix the particulate treating material held within the vessel.  The liquid with the impurities removed, because of the pressure differential between the inside and outside of the vessel, passes through the particulate filter material retained in the small openings of the vessel and is dis- -charged from the housing surrounding the vessel.  The treating ma-terial, once spent, is replaced as necessary.

Abstract: METHOD FOR CONTROLLING TORCH POSITION AND        TRAVEL IN AUTOMATIC WELDING          Abstract of the Disclosure:         To maintain control of arc position in travel along a predetermined welding path, wherein the arc of equivalent heat source is given at least a minimal lateral reciprocation, an elec-trical characteristic, such as current, is sampled to obtain a continuous signal containing a component which varies with lateral position of the heat source.  The first signal is also sampled at the extreme lateral positions of the arc to obtain comparable sig-nal elements which are accumulated, amplified, compared with each other and/or with reference signals, and resultant outputs are used to initiate corrective action.  This action may involve giving warning to a human operator or it may involve partial or full control of a physical or mechanical correction procedure.  A general application is to the welding of a groove formed between adjacent work pieces.  A more specific application is to weld joints involving narrow gaps between lengths of large pipe in pipe-line building.  Moreover, the invention may have application wherever welding is done along a main path having an up-raised element along the path.  The invention is applicable also to situations wherein lateral oscillation is not really required for gap filling but is used merely as a means to isolate control signals for maintaining an accurate center or main line travel position of the arc or heat source.

Abstract: ABSTRACT OF THE DISCLOSURE      The method of unloading bulk materials from vessels resides in a mechanical loosening of the bulk material in the intake zone by virtue of vibration with a simultaneous supply of the aerating air in the direction of the inlet opening of a taking means, the aerating air being supplied pulsewise so that the frequency of pulses is synchronized with the material vibration frequency, taking the loosened and aerated bulk material through suction, and conveying the material by the air.  A device carrying this method into ef-fect comprise a sucking nozzle connected to the material conveying means, a loosening means made fast on the sucking nozzle, and an aerator attached to the loosening means.  The loosening means is made as the frustum of a cone with its smaller base facing downwards and embracing the sucking noz-zle, the lateral surface of the cone being formed by a number of spaced-apart separate ribs, whereas the inlet opening of the sucking nozzle is located below the loosening means. The aerator is located under the nozzle and is made as an annular tube with outlet holes facing the nozzle.  Installed on the loosening means is a pneumatic vibrator whose inlet branch pipe is connected to a pressure line, while its out-let branch pipe is connected to the inlet opening of the aerat-or.
