  • Patent number: 5597495
    Abstract: A method and apparatus for generating a molecular or atomic fluorine jet or beam under vacuum for etching surfaces. The apparatus uses a hollow crystalline tube preferably fabricated from a crystal of a Group II fluoride such as magnesium fluoride. A terminal portion of the tube is heated to over 1000.degree. C. and a mixture of fluorine gas and an inert carrier gas is induced under pressure into the tube. An atomic fluorine jet is emitted from the opposite end of the tube. The jet can be collimated into a beam and can be directed at masked surfaces for selective etching of the surface. The atomic fluorine source has a very high intensity resulting in rapid etching of materials and as a beam is capable of highly anisotropic etching. The jet may be primarily molecular fluorine if the tube is heated to a lower temperature.

  • Patent number: 5595048
    Abstract: A method for wrapping a wrapper about a floral grouping wherein the wrapper is a sleeve or sheet of material having a cinching tab or strip of bonding material or both and a detaching means such as perforations for detaching a portion of the sleeve or sheet of material. The floral grouping is placed on the sheet of material which is wrapped thereabout, or the floral grouping is disposed in the interior space of the sleeve. The cinching tab is attached near one end of the sheet or sleeve.

  • Patent number: 5595248
    Abstract: An apparatus and method for centering a pipe string within a slip bowl to facilitate the setting of a set of slips about the pipe string wherein the slip bowl is disposed in a floor of a drilling rig and the pipe string is suspended from the drilling rig so that the pipe string extends downwardly through the slip bowl and into a well bore. In one embodiment, the apparatus includes at least two pairs of hydraulic cylinders mounted beneath the rig floor about the centerline of the slip bowl. Each pair of cylinders connected by a flexible cable through which the pipe string is run. The pipe string is centered by actuating the cylinders to a retracted position thereby forcibly drawing the pipe string to the center of the slip bowl. Alternatively, the cylinders are provided with a pipe engaging member configured for guiding engagement with the pipe string to push the pipe string into alignment with the center of the slip bowl when the cylinders are actuated to an extended position.
