Abstract: A method and apparatus includes positioning a reactant on a surface in specific location and then directing an energy source from a device at the reactant such that it modifies the surface to either remove material or add material.

Abstract: There is provided a brush holder (40) comprises a body portion (42) fold-lined to a lower closure portion (45) adjacent a front closure portion (46), a top closure portion (50) comprising an upper web (51) having a brush handle aperture (54) formed therein and a closure tab (52). The closure tab (52) is cut at (55) to form a securing tongue (56) adapted in use to engage a securing slot (48) in the front closure portion (46). A left closure leaf (57) is adjacent a tapered left wall portion (60) hinged to the body portion (42) at (43). A right closure leaf (65) is adjacent a tapered right wall portion (66) hinged to the body portion (42) at (43). The upper edge of the left and right closure leaves (57, 65) is provided with a respective integral hanging tab (63, 71) having hanging apertures (64, 72) which are aligned in use. The lower portions of each of the left (60) and right (66) side wall portions are provided with three solvent apertures (74).

Abstract: A method and system includes the accurate positioning of a sample in a multi-axis range of motion. In a preferred embodiment, the present invention enables this movement by combining coarse and fine motion stages. By using a combination of stages and precise measuring means, normal and typical errors are significantly reduced.

Abstract: Process of mixing a fugitive plasticizer, e.g., ethylene carbonate, with moist particulate polyacrylonitrile then removing the water enabling adjustment of the melt viscosity for extrusion of the polyacrylonitrile into film, fiber, pellets and shaped articles. Stretching and heating the extruded polyacrylonitrile film or fiber causes the fugitive plasticizer to exude and vaporize from the film or fiber, carrying with it any remaining acrylonitrile monomer. The resulting film or fiber exhibits substantially increased molecular weight, thus enhancing the tensile strength and barrier properties of the polyacrylonitrile product. The process also produces polyacrylonitrile foam products. A novel cross-linking agent for polyacrylonitrile, divinyloxybutane, is disclosed. Thermostabilizing agents for polyacrylonitrile, N-maleimides and stilbene derivatives, are also disclosed.

Abstract: A method for wrapping a label about a container by employing a solvent activated adhesive composition. The method includes either a shrink wrap method, a mandrel wrapping method or a method employing a preformed roll of flat seamed tubular film. The roll of flat seamed tubular film is bonded at its seam by solvent activated adhesive. A roll for any of these methods with such adhesive, and a container covered by a film which includes strips of such adhesive is provided. A preferred adhesive comprises thermoplastic polyurethane with or without suitable additive.

Abstract: A wire guide for EDM machining apparatus comprises a vacuum hot pressed titanium diboride block having a groove on a curved side of the block for positioning EDM wire. The block has a mounting hole therethrough lined with an electrically insulating sleeve.

Abstract: An elongated flexible form is disclosed. The elongated flexible form may be shaped to fit the contour of a concrete structure of variable shape and is held in position by a plurality of positioning brackets. The flexible form is made out of a flexible material such as natural or synthetic rubber and may be reinforced by metal strips, cable mesh, metal mesh, nylon mesh or a combination of the same. Each of the positioning brackets has a hollow body portion which is molded to a flexible form or welded to a metal plate which is molded to the flexible form. A stake and wedge combination are used to hold each bracket in place. Connecting flanges may be used to attach the end of the flexible form to another flexible form or to a metal form. The connecting flanges are molded or welded to a metal plate which are molded to the end of each form and are held together by a fastening device. The flexible form has a plurality of ribs therealong said form to provide strength and to reduce the required thickness thereof.

Abstract: A torque multiplier consists of a wrench or a set of wrenches, to be used with a torque wrench to increase the capacity of a torque wrench by specific ratios, each having an elongated, non-extensible, straight shank with a laterally extended drive stud at one end and a laterally disposed stud socket at the other end. The studs of each wrench can be made to fit the sockets of each other wrench in the set, so that they can be mounted end to end in a straight line to multiply the leverage, torque foot pounds, or mechanical advantage of a single wrench of the set. The studs, or sockets, may be square or hexagonal and may be of the ratchet type.
