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: The invention comprises a novel method for lubricating and cooling mechanical seals, particularly those seals used in a vertical drill box system. Specifically, the invention utilizes the driving force of the rotating gears in the gear box to convey fluid to an otherwise inaccessible upper seal face. Cooling and lubricating the seal in this manner insures that the various rubber portions of the seal are not degraded by excessive heat. The invention can be utilized in any application requiring sealing of gearing mechanisms from environments containing large amounts of dust or other debris. A preferred application is in mining equipment.

Abstract: A pneumatic winch apparatus applies a constant and non-jerking pull to a cable. The amount of pull or load applied to the cable is determined by the air pressure supplied to an air motor and the radius of a drive wheel connected thereto. A maximum cable-pull load can thus be applied with an automatic non-mechanical cutoff so that a load sensitive cable, such as a fiber optics cable, is not damaged during installation thereof. Moreover, the maximum load is maintained once it has been reached.
Abstract: Disclosed is a vibration damping apparatus incorporated in the crossing of diagonal members such as braces of a framed structure for damping vibration imparted by external force such as an earthquake or a strong wind. The apparatus comprises a plurality of rotatable members or discs, a resistive body disposed between the discs, and a pair or pairs of link bars causing relative rotation of the discs in response to the impartation of the external force, whereby the vibration is damped by the resistance force of the resistive body resisting to the external force.
Abstract: The present invention relates to a novel means placed internally of a tubeless type pneumatic tire, placed upon the drop center rim to effectively transfer heat from the crown and shoulder portions to the sidewalls and the mounting rim during rotational operation thereof by affecting puffs or forcing of the air adjacent the drop center rim up toward the tread and sidewall portions, effectively transferring heat from the tread and sidewall portions down into the heat sink provided by the rim.
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.
