  • Patent number: 5163649
    Abstract: A multi-axis positional gimbal assembly is provided having a junction member with two passageways therein at angles to each other, a first arm sized to insert into one of the passageways and to axially shift therein and a second arm sized to insert into the other of said passageways and to to axially shift therein. The arms are provided with locking means to releasably secure them in the passageways. The upper end of the first arm is mounted to a support member such as a microscope. The distal end of the second (and lower) arm, supports a pallet pivotably mounted thereon at a point removed from the junction member. The second arm is pivotable about the axis of the first arm and also movable up and down on said first arm so as to move such pallet on all three axes, as desired, which pallet can be tilted to any desired attitude and arms and pallet locked in place.

  • Patent number: 4950149
    Abstract: An apparatus for continuously or intermittently molding fiber-reinforced plastic structural components includes a continuous passage or pathway having a series of stations thereon for charging a multiple part mold with a charge of chopped fiber reinforced resin or plastic, closing the mold parts to effect compaction of the charge, curing said charge into a molded article, opening the mold, ejecting the molded article and return the open mold to charging point, movement of said mold parts from open to closed position being controlled by spacing between vertical spaced set of rails supporting male and female parts of the mold, said spacing being controlled to effect indexing of said male and said female part in the curing station in a closed portion and to effect unindexing of the male and female part to open the mold and a method of using said apparatus to yield said molded article.
