  • Patent number: 5784432
    Abstract: A method and apparatus for x-ray measurement of certain properties of a solid material. In distinction to known methods and apparatus, this invention employs a specific fiber-optic bundle configuration, termed a reorganizer, itself known for other uses, for coherently transmitting visible light originating from the scintillation of diffracted x-radiation from the solid material gathered along a substantially one dimensional linear arc, to a two-dimensional photo-sensor array. The two-dimensional photodetector array, with its many closely packed light sensitive pixels, is employed to process the information contained in the diffracted radiation and present the information in the form of a conventional x-ray diffraction spectrum. By this arrangement, the angular range of the combined detector faces may be increased without loss of angular resolution.

  • Patent number: 5312043
    Abstract: A paint striping cart is provided with a parallelogram linkage oscillatable in a horizontal plane. The forward arm of the linkage carries a downwardly directed nozzle which sprays paint in a fan or web, i.e., in a plane. The parallelogram linkage is actuated by a handle and linkage assembly on the cart, the action being such that the nozzle may be swung to any lateral position, within a range of about 60 degrees with respect to the cart longitudinal axis (being its direction of travel) on either side of the cart. In operation, the cart is positioned between a pair of parked cars on a parking lot. So long as neither of the two cars overlies a worn or faded paint line between the cars, the nozzle can be positioned over the worn line and fresh paint discharged from the nozzle to renew the line as the cart is pushed or pulled along a straight path.

  • Patent number: 5288453
    Abstract: A die construction for forming integral hinges (60) for a blow molded carrying case. An edge of the main cavity of a lower die (12) of a blow molding die pair is provided at one peripheral wall portion (40) with sloping channels (38). A core pin (32) extends across and spans the sloping channels. The upper die (10) is provided at one peripheral portion with semi-cylindrical recesses (22) coaxial with the core pin and of the same length as the width of the sloping channel. A heated parison (46, 48) is placed (FIG. 1) between the two dies. With die closing and with the introduction of pressurized air (52) into the parison, the parison is deformed. At the same time, the pressurized air also causes one of the plastic parison sheets (46) of the parison to deform into the semi-cylindrical recess, and the other parison sheet (48) to deform into the sloping channel and also around the core pin. The two parison sheets fuse together around the core pin upon complete closing of the two dies (FIG.

  • Patent number: 5148458
    Abstract: It is often important to measure the phase composition and residual stress resultant from many materials processing procedures. For example, the carburization and heat treatment of steel components where the phase content of austenite versus ferrite or martensite, and residual stress are important characteristics with respect to the ultimate performance of the component. The x-ray diffraction techniques are used extensively to measure both of these characteristics of steel parts. However, the procedures for these measurements are time consuming and must be performed sequentially with any x-ray instrument except that of the present invention. This invention describes a method and apparatus that is able to perform the measurement of retained austenite and residual stress simultaneously. The advantages that the invention offers include very short measurement times and measurement of the characteristics in exactly the same spot of a sample at the same time.

  • Patent number: 5133618
    Abstract: A joint for connecting a tip member to the end of a rod or shaft. The joint is particularly useful for joining a rod end to a tip member of a material which is not easily brazed, cemented or otherwise adhesively joined together. In the specific example described, a ceramic tip is jointed to the end of a metal rod, such as in a plug, a globe, or sliding stem valve. A cavity in the interior of the tip member has a narrowed opening at its top which terminates at a flat surface of the tip member. A pair of wedge members, each of about 180 degrees annular extent, and the headed bolt end are all located in the cavity, with the wedge members oppositely positioned around bolt head. The bolt head and wedge members have complementary tapers so that motion of the bolt away from the tip member cavity causes the wedge members to move radially away from each other and preferably contact the side wall of the cavity, with the cavity being partially closed by an annular overhang through which the bolt shank passes.

  • Patent number: 5066215
    Abstract: An extrusion die for forming honeycomb type structures, such as filters. In a typical prior art extrusion die, the feed holes are circular in cross section throughout their length and feed into respective intersecting discharge slot portions. There is an abrupt change in cross section area and shape, from circular to cross shaped, at the entrance to the discharge slots. This construction results in flow inhibiting land portions at the entrance to the discharge slot portions. Such a construction causes bending forces or moments on these flow obstructing entrance portions of the discharge slots and also subjects them to increased abrasive wear whenever the material being extruded contains ceramic or other hard particles. By this invention, the feed holes are uniformly tapered from an annular or polygonal transverse cross section at their input ends to a (conventional) cross shape at their outlet ends where by feed the discharge slots.

  • Patent number: 4972874
    Abstract: In a power-operated valve in which the pressure of a working fluid is used to control the opening and closing of the valve member in dependence on the condition of an integral power-operated bleed valve, a compensation passage being formed in the valve member to permit working fluid to close the valve when the bleed valve is closed, the compensation passage is formed in that area of the valve member which is bounded by the valve seating and which also defines the cross-sectional area of the inlet chamber, whereby the closing force on the valve member is proportional to the area of the valve housing, thus enhancing the sensitivity of the valve. In a preferred embodiment, a filter is incorporated in the valve member to filter the working fluid to the compensation passage without filtering the bulk of fluid passing through the valve.
