  • Patent number: 5031483
    Abstract: A process for manufacturing tooling, e.g., molds, from individual laminations which when stacked in the proper sequence and bonded together define a forming surface. In producing a mold, cut-outs are made by a 4 or 5-axis cutting means in the individual laminations to provide the shaping surface and optionally passageways adjacent the surface through which a heat transfer medium can be made to circulate. Also, selected ones of the laminations may be spaced in the thickness dimension of the mole to provide communication between the mold cavity and a source of pressurized air or vacuum, or the atmosphere.

  • Patent number: 4389791
    Abstract: A telescopic sight provides means for determining the range of a target of known size and for compensating for predetermined bullet drop over the target range. Reticles are fixed in both the front and rear focal planes of the sight, and first screw means, calibrated to indicate range, are provided for controllably rotating the erector tube to displace the image of the front reticle, formed in the rear focal plane, so as to bracket the target between the rear reticle cross-hairs and the image of the front reticle. Second screw means, also operable to rotate the erector tube, displace the target image so as to compensate for bullet drop.

  • Patent number: 4380876
    Abstract: The reticle is composed of two adjacent parts, each of which comprises a circular periphery with one cross hair extending across the circular periphery. The cross hair on one part is disposed at a 90.degree. angle with respect to the cross hair on the other part to form the reticle aiming point. Each part is made by a chemical machining method.
