Abstract: An automated hole punch including a die plate having a surface including a plurality of spaced apertures extending there through. A plurality of punches, one of the plurality of punches cooperating with each of the apertures. A raised profile extends outwardly from the surface of the die plate and above one or more of the plurality of apertures. A drive mechanism operatively connected to the plurality of punches for moving the plurality of punches toward the plurality of apertures.

Abstract: An electronic scanning radio direction finding system for accurate direction finding of radio frequency signals using singly or doubly flared cylindrical reflectors surrounded by a circular array of inwardly facing feed horns. The array is operated as a phased array to determine the direction of origin of received signals. The feed horns can also be used to transmit RF signals on very narrowly controlled beams with minimal side lobes. The flared cylindrical reflector and its circular feed horn array may be paired with circular log periodic arrays operable at similar frequency ranges or different frequency ranges to provide more precise direction finding and direction finding of signals at frequencies beyond the range of the flared cylindrical reflector and its circular feed horn array.

Abstract: There is disclosed a lure retriever for retrieving a lure on a fishing line, comprising a body, a lure release member mounted to the body and for releasing a snagged lure, and a friction drive system for engagement with the fishing line to advance the lure release member to a snagged lure. This has the advantage of preventing disengagement of the fishing line with the lure which would otherwise occur when the user simply pulls the fishing line. In addition to the foregoing advantage, the friction drive system provided on the apparatus, permits the apparatus to be drivable in a variety of either positive or negative inclinations. This circumvents the difficulties previously encountered in prior art arrangements.

Abstract: A nonwoven fibrous web material that contains cellulose ester fibers, cellulose ester fibrets and a minor amount of activated fusible fibers uniformly dispersed throughout is particularly well suited as a filter media. The activated fusible fibers are effective for retaining within the filter web any particulate material resulting from corrugation without adversely affecting the filtration efficiency of the cellulose ester fibers and fibrets. Alternatively, the fibrous web material may include an effective amount of natural cellulosic fibers.
