Patent number: 4979701Abstract: An elemental net for a multiple element aircraft arresting net system. The elemental net has a single upper horizontal strap, several vertical straps having top ends and bottom ends, and at least two lower horizontal straps. The top ends of the vertical straps are directly affixed to the upper horizontal strap at spaced intervals along the upper horizontal strap. The bottom ends of the vertical straps are alternatingly affixed to one of the lower horizontal straps so that the lower horizontal straps are free to move relative to each other to a significant degree and so that lifting of one vertical strap will tend to lift only one of the lower horizontal straps in the vicinity of the vertical strap being lifted. The present invention provides a variable window which is free to expand or contract during aircraft engagement, permitting easier penetration of the net by a greater mix of aircraft.Type: GrantFiled: March 1, 1989Date of Patent: December 25, 1990Assignee: Patron Inc.Inventors: David K.

Patent number: 4387933Abstract: A control valve is provided for use in brake applications in air-spring equipped railroad and highway vehicles, particularly convertible rail-highway semi-trailers. Such vehicles usually employ pneumatic brake cylinders. The control valve combines the functions of a relay valve with two distinct output limiting characteristics, namely, service and emergency, which output limiting characteristics depend upon vehicle weight is indicated by air spring pressure. The control valve also produces an automatic minimum output to prevent total loss of braking should air spring pressure be lost due to failure.Type: GrantFiled: October 5, 1981Date of Patent: June 14, 1983Assignee: The Bi-Modal CorporationInventor: Christopher A.

Patent number: 4381713Abstract: An air control system is provided for a vehicle convertible between highway and railway modes of travel. Air springs suspend a rail-wheel set axle unit and highway wheel-set axle units from the vehicle body so that the one wheel-set axle unit is stored in a raised inoperative position while the other is in the lowered operative position. During a transfer from the highway mode of travel to the railroad mode of travel, or vice-versa, a valved air control system selectively allows the wheel-set axle units to be positioned in either the raised or lowered positions. The air control system also includes, in addition to the mode selection function, the highway braking function, the rail braking function, the parking brake and the emergency brake functions.Type: GrantFiled: September 25, 1981Date of Patent: May 3, 1983Assignee: Bi-Modal CorporationInventor: Christopher A.
