  • Patent number: 6182596
    Abstract: A system for minimizing the effects of shock and vibration in a high speed vessel with an inner hull and an outer hull. It is a system of dampers, springs and stabilizer linkages in a high speed vessel that control the relative motion of an inner hull to an outer hull, thereby minimizing the effects of shock and vibration in the inner hull. Leaf spring assemblies may be used or as a substitute, torsion rod assemblies may be used, both in combination with dampers such as shock absorbers.

  • Patent number: 6056764
    Abstract: A blade has a proximal end and a distal end and a central axis of elongation. The proximal end is generally rectangular cubic with a flat profile having top and bottom surfaces and short sidewalls, with each sidewall made up of two edges meeting to define an angle of approximately 100.degree. to 140.degree.. The apex of this angle is unsharpened and these sidewalls comprise guide means for guiding movements of the blade through an opening created by the cutting surfaces located on the distal end thereof. The distal end of the blade includes a cutting surface made up of a sharp pointed tip with the cutting edges proximal of the tip defining an angle of 75.degree. to 85.degree.. Two angled surfaces extend laterally and proximally to either side of the tip, each making an angle of 22.degree. to 27.degree. with the bottom surface of the blade. The tip is located between the planes defined by the top and bottom surfaces of the blade. The inventive blade is made from diamond.

  • Patent number: 5947645
    Abstract: A fiber dispensing system for storing and delivering fibrous material includes a housing for receiving and storing the fibrous material. The housing has an activatable dispensing mechanism for selectively dispensing the fibrous material from the housing. A control mechanism is electrically connected to the dispensing mechanism for receiving an activation signal to activate the dispensing mechanism. A load mechanism associated with the housing and electrically connected to the control mechanism measures the weight amount of any fibrous material within the housing and transmits a weight amount data signal to the control mechanism. The control mechanism further activates a solenoid valve which in turn activates a water nozzle spray assembly for wetting of fibrous material prior to discharge into a receptacle.
