Abstract: In the field of security validators, slot acceptors have been known which transport paper offered as a valid security past a testing station. Previously known acceptors have been susceptible to defeat by mosaics, stringing, shocking, photocopy duplication, and the like. Additionally, known acceptors have operated in an analog mode, relying upon rudimentary test functions. The invention herein overcomes the problems of the prior art by presenting an acceptor having a note path (18) characterized by changes of direction (22,24), and which is secured at each end by means of unique gate assemblies (78,98). A plurality of sensors (148-152) are positioned along the note path and are controlled to take a multitude of data samples from the paper as it passes along the path. The data is digitized (236) and used for solving complex transforms, the results of which are compared against results obtained from known valid securities to determine the authenticity of the paper offered.

Abstract: Apparatus comprising a vehicle such as a sledge containing a reel, bin, or the like, holding casing material folded flat, is disposed for travel immediately over an underwater object or piece ground to be covered and is towed by a surface vessel. Situated behind the supply of casing material, relative to the direction of travel, is a table comprising two hinged parts sloping down toward the bottom of the body of water, the lower of the two table parts being arranged to slide over the object or piece of ground to be covered. Concrete of plastic consistence coming from the surface vessel by means of a pressure hose is injected into the casing sliding over the table, the nozzle of the hose being inserted through an opening between the two edges of the casing material. This opening, which may be formed in a zipper by means of two zipper slides, is then closed by joining the two long edges to form the casing.
