Abstract: A disc-shaped, rotary dressing tool has a rigid core and an abrasive rim around at least one surface of the periphery of the rigid core, the rigid core and the abrasive rim being oriented in a direction orthogonal to the axis of rotation of the tool. The abrasive rim comprises an abrasive component bonded to the rigid core by means of an active braze, and the abrasive component is diamond grains arranged in a single layer or diamond film inserts. The abrasive rim may comprise a plurality of abrasive inserts mechanically fastened to the rigid core and comprising an abrasive component bonded to a backing element by means of an active braze.

Abstract: A combination mounting ring of resilient material, for connecting a shaft within a bore of a housing, has a hollow cylindrical part having radially extending projections. This part is for locating between the outer surface of the shaft and the inner surface of the bore, the radially extending projections being under compression and thus securing the shaft within the bore. The combination mounting ring further has an axial spring element extending radially inward from the cylindrical part and having two portions at different axial positions. The axial spring element is for locating between the shaft and a body axially displaced from the shaft, and serves to minimize axial movement of the shaft within the bore of the housing. The axial spring element may either be an annular part or a tab extending from an axial edge of the cylindrical part.

Abstract: The present invention provides thickened fabrics and reinforcements for use as a spacer or reinforcement for a matrix system. The fabric includes in a first embodiment a woven fabric comprising weft and warp yarns containing glass fibers. A portion of the weft yarns are undulated into a sinusoidal path forming a generally “C” shaped bridge between adjacent warp yarns which results in an increased thickness for the fabric. The fabric is coated with a polymeric resin or bonding agent, for substantially binding the weft yarns in the undulated condition. This invention also includes methods for making such fabric by increasing the thickness of a woven or non-woven material by such methods as applying tension to warp yarns having opposite twists during weaving operations, or using unbalanced yarns, for example.

Abstract: An ion source impinging on the surface of the substrate to be coated is used to enhance a MOCVD, PVD or other process for the preparation of superconducting materials.

Abstract: The present invention relates to a knitting tool 1 in which a knitting point 2 is joined to a flexible cord 3 for holding the knitted product, wherein the knitting point 2 and the flexible cord 3 are joined to one another by means of a coupling device 4 and the coupling device 4 has at least two elements 5, 6 that can be releasably coupled to one another by means of a bayonet catch.

Abstract: A detector includes a sonde having a housing and comprising a scintillator disposed within the housing and a calibration source coupled to the scintillator to fluoresce the scintillator at a known wavelength of electromagnetic radiation. The detector further includes an electromagnetic radiation sensing device coupled to the scintillator and disposed within the housing and a first programmable/re-programmable processing module (PRPM) coupled to the electromagnetic radiation sensing device and disposed within the housing. The PRPM is programmed to process signals from the electromagnetic sensing device based on a user-defined analysis mode selected from the group of modes consisting of filtering, windowing, discriminating, and counting.

Abstract: An aggregate material includes an aluminous material and a toughening agent in contact with the aluminous material. The aluminous material has a primary aspect ratio of at least about 1.5 and a particle size between about 30 nm and about 1000 nm.

Abstract: Pulp production techniques are disclosed. In one embodiment, pulpstone segments are provided, that include proppant grits in the place of some or all of the conventional abrasive typically used in pulpstone applications. The proppant or proppant-abrasive mixture can be combined into a three-dimensional matrix supported by a vitrified bond. Alternative embodiments use proppant grits in an organic bond or a metal bond or a cement bond (each of which may also include abrasive grits in addition to proppant grits). The proportion of proppant grits to abrasive grits can be varied to produce pulp of varying fiber length distribution as required by the end-user (e.g., paper mill). The greater the proppant concentration, the less cutting of the fibers by the conventional abrasive will occur, producing a greater percentage content of longer fibers. Such pulp produces higher quality paper.

Abstract: A method of forming a roofing product can include providing a ceramic base material having an open structure. The method can also include filling the open structure of the ceramic base material with a bituminous material, wherein the bituminous material has no greater than approximately 5 weight % of abrasive particles. The method can further include applying a recycled roofing material adjacent to the ceramic base material after filling the open structure of the ceramic base material with the bituminous material. In a particular embodiment, an open structure of the ceramic base material is filled with a bituminous material that has no greater than approximately 2 weight % of abrasive particles or 0.1 weight % metal content. The recycled roofing material can be applied along one or both sides of the ceramic base material. The bituminous material may have a characteristic particle size that is smaller than a characteristic particle size of the recycled roofing material.

Abstract: Various single crystals are disclosed including sapphire. The single crystals have desirable geometric properties, including a width not less than about 15 cm and the thickness is not less than about 0.5 cm. The single crystal may also have other features, such as a maximum thickness variation, and as-formed crystals may have a generally symmetrical neck portion, particularly related to the transition from the neck to the main body of the crystal. Methods and for forming such crystals and an apparatus for carrying out the methods are disclosed as well.
