  • Patent number: 4513439
    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.

  • Patent number: 4488729
    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.

  • Patent number: 4482133
    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.

  • Patent number: 4480731
    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.

  • Patent number: 4480943
    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.

  • Patent number: 4480250
    Abstract: A credit card carrier includes a pair of flaps foldable upon each other. Each of the flaps carries clip switches adapted for receiving credit cards therein. The clip switches are arranged in parallel interconnection with each other, and in series interconnection between an alarm and a battery. When a credit card is missing from one of the clip switches, the circuit between the battery and the alarm is completed and the alarm is energized. The flap also includes a proximity switch such that interconnection between the battery and the alarm is disabled until the flaps are folded onto each other.

  • Patent number: 4478023
    Abstract: Apparatus for automatically receiving and opening the four flaps of a cardboard case or the like. The invention includes a conveyor system for transporting cases in spaced relationship with each other past a pair of vacuum-actuated hinged shoes which engage and partially open the side flaps and direct the same into a plow. The plow completes the opening of the side flaps. A pair of brushes, having common drive, but opposite rotation, are adapted for opening the front and rear flaps. A fabric belt engages and holds the front flap down, while a rotating arcuate member makes hold-down contact with the rear flap. The apparatus is adjustable to accommodate cases and flaps of varying dimensions.

  • Patent number: 4476489
    Abstract: An apparatus and technique for measuring microfinishes of workpieces at on-line speeds. A digitized image of a finished surface of a workpiece is generated. Under microprocessor control, a distribution of the digitized values is obtained. This distribution is compared against pre-stored distributions of known surface finishes to determine the type of finish of the workpiece and/or the acceptability of the finish. The comparison is obtained using curve matching techniques and by comparison of mean gray level values.

  • Patent number: 4475715
    Abstract: An aerial block which is releasably mounted on a support cable either at a pole or in a span between two poles for installing coaxial aerial cable which then is secured to the support cable. The block has a frame formed by two spaced generally L-shaped members connected by a lower stabilizing bar. The vertical upstanding portion of each L-shaped member has a hooked end which suspends the block from the support cable at a pole location. The stabilizing bar abuts the pole to maintain the frame in a position wherein the leg members extend horizontally outwardly from the pole to provide two spaced points of support for a coaxial cable being installed to prevent kinking or bending of the cable. A spring-biased plunger mechanism is provided on each of the vertical leg members for releasably attaching the frame on the support cable between poles.
