  • Patent number: 5869178
    Abstract: Disclosed are profiles of fiber-reinforced polymeric plastic and a pultrusion apparatus and method for the manufacture thereof. The apparatus is preferably vertically disposed. As one or more fibers is fed into the apparatus, each fiber is spread and wetted with monomer resin in a bundle spreader, formed in a die, and then subjected in a curing chamber to a source of radiation which initiates polymerization of the monomer, resulting in a fiber-reinforced polymeric plastic exiting from the pultrusion apparatus. Suitably, the radiation is ultraviolet, the monomer resin is methacrylate resin, and the fiber is quartz. The resultant profile is long and thin like a structural steel wire, but typically will have only 1/4 the weight thereof while having a strength comparable thereto. Thus, the profile is useful as an orthodontic wire as a replacement instead of structural steel wires used as orthodontic wires.

  • Patent number: 5785042
    Abstract: A method for correcting striation artifacts that are generated during a magnetic resonance imaging method. The method involves generating an image of a body area. The image is reconstructed from raw data collected in a spatial-frequency domain. As some of the data points in the raw data from which the image is generated are corrupted, the image of the body area contains striation artifacts. A region containing a homogenous material is selected. Next, the corrupted data points in the raw data are detected and corrected vis-a-vis a Fourier transform correction process, and a new corrected image essentially free of striation artifacts is generated.

  • Patent number: 5752457
    Abstract: A tufting machine comprising a drive shaft, an eccentric rotatable by the drive shaft, a connecting member (6) mounted at its proximal end for rotation about the eccentric (4) and coupled at its distal end to pushing means (26) for pivotal movement in relation thereto, a needle mounting means associated, for reciprocating movement, with the said pushing means (26) which impart the reciprocation to the needle mounting means under the impulse of the connecting member (6). The connecting member comprises at least two parts, a distal part (22) for engaging the pushing means and an adjustable proximal part (24) for engaging the said eccentric, the adjustment being possible by varying the position of the proximal part with respect to at least a part of the said eccentric (4). The variation may be provided by a split eccentric with inward facing grooves (10, 12) on the two parts to vary the relative position and thus the focus of the eccentric may be varied without providing a replacement eccentric.

  • Patent number: 5746789
    Abstract: A radial inflow centrifugal filter device for separating fine particulates from a fluid flow, including a rotatable plurality of hollow parallel disks mounted in spaced apart relationship and attached via spacers to a tube. The hollow drive tube is in flow communication with the interior hollow plenum of the disks which is at a lower pressure relative to the open space between the disks. Rotating the tube causes the disks to rotate. Particulate-laden fluid is allowed to enter the filter device at the perimeter of the rotating disks and experiences a change in momentum due to the interaction of boundary layers of fluid established on each side of every disk. The centrifugal force imparted to both the fluid and particulates causes them to be separated in opposite directions.

  • Patent number: 5725449
    Abstract: An impact pulley apparatus and method are provided for use with a high-speed media processing apparatus by driven attachment to the rotatable shaft of a motor associated therewith to absorb impact energy caused by the high-speed media processing apparatus encountering media to be conveyed. The impact pulley apparatus includes a base plate for mounting on the rotatable shaft such that rotation of the shaft causes identical and simultaneous rotation of the base plate. A pulley member is operatively connected to the base plate by biasing members which are springs in the preferred embodiment such that the pulley member is substantially identically rotatable with rotation of the base plate in one direction in a non-actuated position until an amount of impact energy is encountered by the pulley member sufficient for the pulley member to biasedly rotate in the same direction less than the base plate in an actuated position of the impact pulley apparatus in order to absorb the impact energy.
