  • Publication number: 20200222711
    Abstract: A system and method for imaging or treating a disease in a human or animal body. The system provides to the human or animal body a pharmaceutical carrier including one or more phosphors which are capable of emitting ultraviolet or visible light into the body and which provide x-ray contrast. The system includes one or more devices which infuse a diseased site with a photoactivatable drug and the pharmaceutical carrier, an initiation energy source comprising an x-ray or high energy source which irradiates the diseased site with at least one of x-rays, gamma rays, or electrons to thereby initiate emission of said ultraviolet or visible light into the body, and a processor programmed to at least one of 1) produce images of the diseased site or 2) control a dose of said x-rays, gamma rays, or electrons to the diseased site for production of said ultraviolet or visible light at the diseased site to activate the photoactivatable drug.

  • Publication number: 20200191250
    Abstract: A gear comprising an annular gear component 12, a drive transfer section 24, the drive transfer section 24 being of composite material form, the drive transfer section 24 including a flange region 28 for engagement with the gear component 12, and a hoop element 32 applying a load to the flange region 28 to compress the flange region 28 against the gear component 12 and provide support for the gear component 12.

  • Publication number: 20190242504
    Abstract: A fuel pipe having an elongate tubular body 12 of fiber reinforced composite material form, the material including a conductive material powder to render at least a part of the body of limited electrical conductivity, the tubular body 12 having a fitting 14 formed thereon or secured thereto to allow a part of the body 12 to be sealed to another component, wherein the fitting 14 is of an electrically non-conductive material.

  • Publication number: 20080012329
    Abstract: A fibre reinforced composite shaft (Co) bearing a metallic flanged end coupling (Me) attached to the outside diameter through a concentric cylindrical torsional joint, The composite tube is press fitted into a flanged metallic end coupling (Me) comprising a multiplicity of teeth (Te) running parallel to the tube axis which cut longitudinal channels into the outside diameter of the composite tube wall during the press fit process. Pairs of inverted troughs (Tr) adjacent to and running parallel to the cutting teeth in the serrated region allow space for the redistribution of the composite material and debris (Deb) formed during the press fitting process. This combined action forms a mechanical interface (In) capable of supporting torsional and axial stresses. A structural adhesive (Ad) may be applied to the joint region to form a secondary joint. In this case the composite formed between the cutting debris and the adhesive fills the trough channels.

  • Publication number: 20060258469
    Abstract: A fibre reinforced composite shaft bearing a metallic flanged end coupling (F1) attached to the outside diameter through a concentric cylindrical torsional joint, comprising: a)—a cylindrical end region comprising a wedge shaped inner layer of fibre (Hp) composite; b)—a layer of outer helical composite plies (He) forming the shaft and extending over the wedge shaped inner layer, wherein the layer of outer helical plies has a tapered end part overlying wedge shaped inner layer to form the cylindrical end portion, wherein all helical plies of fibre layers are exposed on an outer surface; and c)—a metallic flanged end coupling attached to the outer surface of the cylindrical end region through a primary mechanically interface (Sp) which may be splined. The joint may be strengthened by internally reinforcing the main shaft with an interference fit tubular plug (Pg) and protected from environmental degradation by inboard secondary adhesive bond (Ad).
