Abstract: A technique for providing a grid for a gate such as utilized in gating a stream of ions or other particles in a spectrometer instrument. The grid of wires may, for example, be a so-called Bradbury-Nielson Gate that consists of a set of two electrically isolated sets of equally spaced wires that lie substantially in the same plane and alternate in potential. The method utilized to provide is to first fabricate a frame of an insulating substrate having a hole and depositing metal film patterns such that conductive portions are formed on either side of the hole. Conductive portions on either side form a series of terminating pads on the portion of the substrate closest to the hole and a bus bar. Grid wires are then formed by stretching a section of wire with desired constant tension across the hole and bonding the ends of the wire to a respective one of the pads on one side and bus bar on the other side. The method provides a rapid, inexpensive way to fabricate such modulating devices.

Abstract: A two-piece clamping arrangement for engaging and holding an elongated element, such as a tubular conduit for fluids, or the like. An upper and a lower clamp member are provided to engage oppositely-facing surfaces of the elongated element. One of the upper or lower clamp members includes at least one longitudinally-arranged alignment surface to assure proper alignment of the clamp members when the clamp is assembled about the elongated element. The alignment surface also serves to stiffen the clamp member against bending and thereby serves to increase the holding force of the clamp assembly.

Abstract: A spectroscopy instrument that uses spectra produced from random binary sequence modulated data. Statistical estimation techniques are used to achieve resolution enhancement, while properly accounting for the Poisson noise distribution and other artifacts introduced by a modulator or “chopper” or other system components. Indeed, a resolution similar to that of modern spectrometers can be achieved with a dramatic performance advantage over conventional, serial detection analyzers. Both static and dynamic behaviors are theoretically or measured experimentally accounted for in the model as determined. In one embodiment, the finite penetration of the field beyond the plane of the chopper leads to non-ideal chopper response, which is characterized in terms of an “energy corruption” effect and a lead or lag in the time at which the beam responds to the chopper potential.

Abstract: A method for joining two or more substrates with a seam is provided. The seam is formed with a thermoplastic tape that is capable of forming an adhesive bond and a physical bond with a substrate. For instance, in one embodiment, the thermoplastic tape is formed from a polyurethane film. In addition, the seam can be utilized in a flat configuration or folded into a variety of different shapes, such as in a z-shaped configuration. As a result of the present invention, it has been discovered that a seam can be formed to have improved strength without substantially sacrificing the desired functional properties of the substrate materials.

Abstract: A teartape for packaging materials, and particularly such materials based on polyolefin films, includes a base film coated with a pressure sensitive adhesive composition. The teartape is affixed to the packaging material by the adhesive composition. This avoids the problem of distortion which can occur when affixing conventional teartapes to such packaging materials by means of hot melt wax compositions. The teartape is applied to moving packaging material by controlling the speed of the teartape in accordance with the speed of the packaging material so as to reduce tension imbalance. The speed of the teartape may be controlled in dependence upon the tension in the teartape. This can be achieved by supplying the teartape from a dispenser having a brake means (4,5) and a drive means (10,11,12) for regulating the speed oft he teartape in dependence on the tension in the teartape.

Abstract: A method and apparatus for signal mediation in a common channel signaling network are described. The method involves identifying candidate message signal units that require mediation and transmitting the candidate signal unit to an associated mediation function which performs access mediation on the contents of the candidate signal unit. The access mediation function may return one or more data packets to the network. The apparatus includes the signal transfer point, the associated mediation function and enhanced functionality in the signal transfer point for screening candidate signal units. The advantage is a more flexible and easily managed signal mediation point that removes the bulk of signal mediation from the signal transfer point so that the signal transfer point can remain dedicated to its signal transfer function.

Abstract: A computer implemented method of underwriting profitability analysis delivers the analytic process to a wide cross section of insurance decision makers. The underwriting profitability analysis system leverages an existing investment in databases and improves underwriting business processes. Data mining techniques are applied to historical policy and claims to extract rules that describe policy holders with homogeneous claim frequency and severity characteristics. These rule sets are used to classify policy holders into distinct risk groups, each with its own set of characteristics, including pure premium. Breaking up a book of business into segments allows identification of sub-populations of policy holders that distinctly deviate from the expected normal pure premium. This identification allow the insurance business analysts to interactively adjust eligibility criteria and examine altered characteristics of the covered segments until satisfactory.

Abstract: A thermal imager referencing system comprises two rotating cranks in the form of discs (7, 8) each pivotally attached to connecting member (9). The discs (7, 8) are rotated at a constant speed causing two mirrors laterally displaced along connecting member (9) to intercept an optical path X of a thermal imager associated with the referencing system. Each rotation through 360 degrees of the discs (7, 8) causes each mirror to pass once through the optical path, the mirror surfaces being respectively arranged to cause a linear array of detector elements (not shown) of the thermal imager to view alternately thermo-electric devices (14, 16), which are at different temperatures, during the flyback time associated with the thermal imager. The referencing system enables processing means of the thermal imager to normalize the detector array, compensating for DC offset and differences in gain between different elements of the detector array.

Abstract: Load measuring apparatus particularly but not solely for the weighing of animals is supported on load-bearing feet. Each load bearing foot provides an electrical signal indicating the load thereon and the sum of the electrical signals indicates the total load. Each load bearing foot has a strut which is in use attached to the load, housing which rests on a load-bearing surface and a load cell which is fixed within housing and transmits the load force carried by strut to housing and thence to the load-bearing surface. The strut passes through an aperture in housing to bear against load cell which is in the central cavity of the housing. The strut is able to move towards load cell, but is substantially restricted from moving away from the load cell, and preferably is able to have some rotational movement relative to base. The load-bearing feet overcome the bulkiness and expensiveness of prior art weighing systems and are portable, inexpensive and accurate in use.
