IPC: H05K3/34
Filed: 1995-08-18
Granted: 1999-12-21
Abstract: Solder pastes presently harden or congeal over time. This results in wasted solder paste and in production down time. This hardening is a result of the long polymer chains created by the dicarboxylic acid in the activator and the indium (In) or tin (Sn). A solder paste is described in which the metal alloy is coated by an agent that inhibits the reaction with the dicarboxylic acid. One solution involves coating the metal alloy powder with monocarboxylic acids, which truncate the polymer chain. Another manner for truncating the polymer is to coat the metal alloy powder with complexing agents. The metal alloy powder can also be coated by a stable metal such as lead (Pb), gold (Au), silver (Ag), bismuth (Bi), palladium (pd), platinum (Pt), a silver palladium alloy (AgPd) or a silver platinum alloy (AgPt).

Abstract: Apparatus and in vivo methods for distinguishing normal and abnormal cervical tissue and detecting cervical intraepithelial neo-plasia (CIN) in a diagnostic tissue sample. A source of electromagnetic radiation (36) is applied to the diagnostic cervical tissue sample and the presumptively known normal cervical tissue. Fluorescence intensity spectra induced in the diagnostic tissue sample and the presumptively known tissue by the radiation source is detected by at least one radiation detector (26).      A computer (20) is programmed to measure a peak normal fluorescence intensity value in each of the normal fluorescence intensity spectra, to calculate an average peak normal fluorescence intensity from the peak normal fluorescence intensity values, to measure a peak fluorescence intensity value from the fluorescence intensity spectrum induced in the diagnostic tissue sample, to calculate a slope parameter which is indicative of tissue abnormality, to calculate relative peak fluorescence intensity as a function of the peak intensity value, the average peak normal intensity, and to detect tissue abnormality as a function of the slope parameter and the relative peak fluorescence intensity.

Abstract: An elongate cultivating tool adapted to be supported at each end so as to be able in use to rotate about a longitudinal axis. The cultivating tool comprises an elongate cylindrical support (1) which may be a helical coil spring, a plurality of cultivating elements (2) on a peripheral cylindrical surface of the cylindrical support, each cultivating element linking up with four other like cultivating elements on the peripheral cylindrical surface and one and preferably two tines (3) extending from each cultivating element. There may be two banks of cultivating elements on the tool to give a greater number of tines on the tool. The axle (6) to support the cylindrical support for rotation may be telescopic to provide tension to maintain the position of the cultivating elements. The cultivating elements are formed from metal rod and in one form comprise a U-shaped body with each leg of the U-shaped body including a bend out of the play of the body with each portion beyond the bend comprising a tine.

Abstract: Extruded pellets comprising a majority of activated carbon particles and an inorganic binder are disclosed to provide improved performance when processed through tumbling equipment while the pellets are in their "green" state (i. e. , pellets which are fresh off the extruder'and contain activated carbon), binder material, and water and have not been subjected to any thermal processing (drying or calcining). The tumbling action both smooths and densifies (i. e. , reduces interparticle voids within) the pellet, thereby closing any cracks and greatly improving appearance. Improved performance results from an ability to increase the weight of carbon pellets which can be packed into a fixed volume and thereby increase the volumetric working capacity of the bed for adsorbing/desorbing vapors. Another benefit is to greatly reduce the levels of dust associated with the carbon, both the initial dust and the dust attrition.

Title: Reinforced thermoplastic molding technique method and apparatus
Inventor: GREVE BRUCE NORMAN
IPC: D21J7/00
Filed: 1996-05-13
Granted: 1999-07-06
Abstract: A method and apparatus for binding the fibers of,  and forming a fiber reinforced plastic structure. A fiber reinforced plastic preform is created by depositing a mixture of reinforcing fibers, binding fibers and resin matrix fibers on a screen having a preselected geometry.  The fiber reinforced plastic preform is exposed to high temperature fluid causing the binding fibers to melt and, thereafter, to cool air to temporarily bind the preform in a tackified state.   The tackified preform is exposed to a higher temperature fluid causing the resin matrix fibers to melt and, thereafter, to cool air to solidify and thus bind and lock the reinforcing fibers of the tackified preform in place to create a homogeneous fiber reinforced plastic structure.

IPC: G01L1/24
Filed: 1996-10-23
Granted: 2005-12-20
Abstract: This invention provides an optical and computation system that does not utilize moving parts, which enables the angular orientation of the optical axes on the surface of a birefringent material to be determined and comparably, the orientation of the optical axes within light emerging from that surface. Further, since this invention considers the relative orientations of the preferred axis or axes of polarization within light, this method is also applicable for determining the angular orientation of the preferred axis of polarization of elliptically or linearly polarized light or the orientation of the polarizing axis of the material causing the preferred direction of polarization. For birefringent generated axes, this invention allows for the principal axis to be identified distinctly from the quadrature axis and without ambiguity. This is achieved by consideration of the relative intensities of the light emerging from the birefringent or polarizing material when observed through a plurality of linear or elliptical polarizers whose axes are set at known and distinct orientations to the reference direction of the measurement system, and with the ambiguities in the determination of the principal axis in the birefringent system removed by use of the phase of the interference patterns resulting when the light passing along the principal and quadrature axes within the birefringent material is combined by the linear or elliptical polarizers.

Title: Tire having flow isolating grooves
Inventor: WHITE TIMOTHY ANDREW
IPC: B60C11/13
Filed: 1997-01-07
Granted: 2002-09-03
Abstract: A tire having a decreased percentage of void and superior  wear  abilities,  yet  still  having  improved  wet traction ability is disclosed.   The improved wet traction ability is enhanced by the flow isolating characteristic of the minor grooves of the tire.   By reducing the amount of water  flow  between  the  major  and  minor  grooves  for  a prescribed period during which the major grooves evacuate water away from the tire, there is a reduction in the volume and nature of turbulence due to the intersecting water flows exiting the minor grooves into the major grooves.   This reduction of turbulence allows for fluid to be properly channeled away from the contact patch area by their major grooves.
