Abstract: Helmet mounted display apparatus for use in aircraft and rotorcraft includes an image source for generating images that are projected into the pilot's forward field of view by a portion of relay optics that are common to both day and night viewing and interchangeable optical eyepieces, one for daytime viewing and one for nighttime viewing.

Abstract: A universal tail pipe connector includes a three-way valve disposed on a hollow, cylindrical housing having inlet and outlet ports in spaced registration along the longitudinal axis of the housing, each having an internal diameter at least as large as the largest outside diameter tail pipe to which connection is required, the connector further including an annular, inflatable seal of elastomeric material disposed in an annular collar portion of the housing adjacent the inlet port, the seal being responsive to positive pressure and vacuum pressure signals provided through the three-way valve from external sources of each in dependence on selectable operation by an operator, for retracting inside the annular collar in response to the vacuum pressure signals to permit unobstructed penetration of the tail pipe through the inlet port into the housing, and for inflating in response to the positive pressure signals to provide a surface seal along the contour of the outside diameter of the enclosed tail pipe.

Abstract: A hydraulic logsplitter assembly including a logsplitting mechanism and comprising means for charging logs thereto consisting of:a boom,a support mechanism supporting the boom and disposed at an angle from the vertical centerline for facilitating the free swinging of the boom at an angle from on an inclined plane under the weight of a load between charging and discharging positions,a base for rotatively supporting the support mechanism,a torsion spring interconnecting the base and support mechanism for the swinging returnably of the boom from discharging to charging position,a cable supported by the boom,a grapple unit mounted at the free end of the cable.

Abstract: Connection is quickly made to a plurality of fluid lines, the pressure or other non-flow characteristic of which is desired to be measured, by means of a vehicle mounted port block container valved access to a plurality of vehicle fluid lines and a matching transducer block having a corresponding plurality of transducer retaining bores correspondingly aligned for close fluid communication with one of the ports, each containing a pusher to open the valve of the related port and each containing a fluid-to-electric parameter transducer for measuring a parameter of fluid in a corresponding port, there being an electrical interconnection means, such as a cable, for carrying conductors to the transducers. A locking means provides for snugging the transducer block tightly against the port block and for locking the blocks together by two independent motions of a locking handle.
