Methods and apparatuses for filling flexible receptacles or bags with bulk or particulate material is provided. In one aspect, an automatic sand bag filling apparatus is disclosed which includes a bulk fill channel which may be placed within the interior of each bag to be filled. The filling apparatus may have a metering device for providing the desired amount of bulk material to the fill channel. The fill channel may be moveable along a fixed path for engaging and advancing a series of interconnected bags. Articulating spreader bars may be provided to support the bag during filling. In one embodiment, the filling apparatus is mounted on a trailer assembly and includes a reservoir for storing the bulk sand. The sand may be transferred from the reservoir to the filling apparatus using augers, conveyors, etc. A preferred construction of a series of interconnected sand bags and a method of making a series of interconnected bags is also disclosed.

A method for deriving an interlaced television signal from an interlaced 625 line, nominally 50 Hz field rate television signal, the derived television signal having perceived reduced line structure and perceived reduced flicker, comprising, in either order, increasing the field rate of the derived television signal with respect to the field rate of the original television signal, such that the increase in field rate reduces perceived flicker in the derived television signal, and increasing the number of lines in each field of the derived television signal with respect to the number of lines in each field of the original television signal, wherein the line rate is increased to an odd number of lines in the range of 821 to 839 lines, such that the increase in lines reduces perceived line structure in the derived television signal, wherein the increase in the field rate and the increase in the number of lines in the derived television signal results in a horizontal scanning rate that does not substantially exceed twice the horizontal scanning rate of the original television signal while minimizing undesirable motion artifacts. 11. The method of claim 10 wherein the line rate is increased to 825 lines. 12. A method for deriving an interlaced television signal from an interlaced 625 line, nominally 50 Hz field rate television signal, the derived television signal having perceived reduced line structure and perceived reduced flicker, comprising, increasing the field rate of the derived television signal with respect to the field rate of the original television signal, such that the increase in field rate reduces perceived flicker in the derived television signal, said increasing the field rate comprising deriving two or three signal streams from said original television signal, each of said signal streams comprising a pattern of n repeated time-compressed fields, each of said signal streams having a field rate substantially equal to said increased field rate, all of fields in a signal stream being of the same parity, at least one signal stream consisting of even parity fields, each field in a signal stream being substantially identical in information content to each consecutive field of the same parity in the original television signal, deriving a further signal stream from said two or three signal streams by alternately selecting even and odd fields from said two or three signal streams, and deriving yet a further signal stream from said two or three signal streams by alternately selecti
