  • Patent number: 6453873
    Abstract: A system and method for controlling combustion engine compression braking having the variable timing of the dwell period of at least one exhaust valve by an electronic control module within each one of the engine cylinders during a braking event as well as the variable timing of the commencement or onset of the braking event. The system and method thus facilitate the proper performance of the braking event as a function of engine speed and prevents interference or physical impact with the cam driving elements used for achieving the normal or regular exhaust valve event.

  • Patent number: 4507011
    Abstract: A reinforced elastomer attachment joint includes an elastomer section (304) butt bonded to a FIBERGLAS section (332), a boundary line (340) being defined therebetween. One or more fabric plies (338) are embedded within the elastomer (304) and FIBERGLAS (332) sections so as to be capable of transmitting loads from the elastomer section (304) to the FIBERGLAS section (332). The rigid FIBERGLAS section (332) is capable of being drilled and countersunk so as to accomodate fastening means (306) whereby the attachment joint can be secured to basic support structure (302).

  • Patent number: 4448372
    Abstract: An aircraft vertical fin-fuselage structural integration system wherein a plurality of vertical tail fin spars, extending transversely across the fin and fuselage and substantially parallel to the longitudinal axis of the fin, are integrally connected directly to the fuselage pressure bulkhead so as to directly transmit or transfer the vertical fin and horizontal stabilizer empennage loads to the fuselage structural network. The system can be adapted to any type of aircraft, and in the case of an aircraft of the BOEING 727 class, the spars accommodate the air intake S-duct operatively associated with the craft's rear engine housed within the rearwardmost portion of the fuselage. The spars also have their lateral configurations fabricated so as to match the fuselage loft lines.

  • Patent number: 4437627
    Abstract: An integrated power plant installation system for underwing high-bypass mid-length fan air duct core-mounted engines readily permits disconnection of the entire powerplant at the wing thereby virtually eliminating the necessity of disconnecting the engine and complex systems per se from the support strut when engine replacement or removal proves necessary. Excessive congestion within the vicinity of the strut box structure is eliminated by disposing the engine accessories, and auxiliary equipment and system lines, within the lower quadrant of the powerplant assembly in both a laterally and longitudinally distributed array. Potential catastrophic fire hazards within the nacelle are substantially eliminated by routing the fluid lines and electrical conduits axially aft and upwardly around the circumference of the engine within the nozzle section of the powerplant aft of all rotating discs.

  • Patent number: 4437629
    Abstract: A seat structure includes a flexible canvas seat bottom portion (14) and a flexible canvas seat back portion (12). A horizontally disposed, transversely extending beam member (58) is rotatably disposed above the seat bottom portion (14) and is operatively connected to the lower end of the seat back portion (12). The beam member (58) is movable between two positions 90.degree. apart such that when the beam member (58) is disposed in its first position, the beam member (58) effectively defines a support shelf or platform projecting forwardly of the seat back portion (12) and is therefore capable of supporting parachute packs borne by parachuting personnel seated within the seat structure. The seat back portion (12) is also disposed in a slackened state at such time so as to accommodate the depth of the parachute packs.

  • Patent number: 4256442
    Abstract: An improved peristaltic pump includes a pivotably mounted pressure plate which, together with the pump roller elements, defines the pump chamber. The pivotal mounting of the pressure plate facilitates accessibility to the pump chamber in order to simplify the pump tube loading and unloading procedures. The mounting system for the pressure plate includes a mechanically-advantaged four-bar linkage arrangement which automatically retains the pressure plate in either its fully open or fully closed position as a result of an over-center type locking construction. The pump also includes a mechanism for adjusting the volume flow rate characteristic of a pump tube. This is particularly adaptable for a dual-tube system wherein a predetermined volume flow rate ratio is to be achieved.
