Abstract: The invention relates to plastic bags and sack for use especially in the food and pharmaceutical industries. The bag (2) comprises inner and outer bag sections (4, 14) which are joined at least at an upper portion in a manner which allows them to be separated when required, such as by heat sealing. The outer bag section (14) may be provided with a mouth (10) through which the inner bag section can be withdrawn when required. Alternatively, the outer bag section may be peeled away from the inner bag section. The inner bag section is heat sealed after filling with contents to retain the contents in the inner portion. The heat sealing step also serves to secure the bag sections together as above. The inner bag section is preferably provided with a closeable mouth (132) separate from the end by which it is filled, through which the contents may be dispensed.

The method is equally useful, depending on the starting material, for the production of enantiomerically-pure compounds, or mixtures with arbitrary enantiomeric content.

Abstract: A calibration engine, which seeks to eliminate disconnects between both manual and automated calibration procedures. It abstracts the process of procedure development such that procedure writers can produce automated procedures without being computer programmers. By organizing calibration procedure elements in a relational database format, a relational automated calibration engine (RACE) provides the mechanism whereby a single calibration procedure can be executed in either a manual, automated, or semi-automated fashion. It supports pre-engineered standard substitution, is cross platform, and seeks to preserve the investment of existing calibration procedures. In order to work in multiple deployed environments, RACE has been authored to ensure maximum flexibility with regard to required hardware and software. The engine can operate both with and without an installed operating system and relational database server.

Abstract: An apparatus, for weaving leno fabric on a loom, including: a support having pivot means which enable the support to be pivotally mounted on the loom for reciprocal pivotal rotation about a pivot axis, the support carrying a plurality of ground thread blades arranged side by side in a row and spaced apart along the row to define in between neighbouring ground thread blades a guide space for a ground thread running along a predetermined pathway, a leno guide blade being located in each guide space to divide the guide space into first and second guide slots, each leno guide blade having at its terminal end a leno guide eye through which a leno thread is to be guided, adjacent ground thread blades projecting beyond the terminal end of the leno guide blade located therebetween to define a ground thread cross-over space, the ground thread and leno guide blades being arranged to extend from said pivotal axis as defined by the pivot means such that pivotal movement of the support in a first rotary direction causes t

Abstract: A three-dimensional zipper pull tab attachment mechanism providing an enlarged gripping surface for facilitated location and manipulation of a pull tab, which is particularly useful in connection with diving equipment and by those having limited finger dexterity. The body of the pull tab attachment comprises mating male and female components, wherein male component comprises a locking arm sized for insertion through a zipper pull tab aperture and dimensioned to matingly engage the female component by way of a correspondingly shaped channel region extending at least partially therethrough. Upon appropriate engagement of male locking arm with a zipper pull tab and female component, a three-dimensional pull tab attachment having an enlarged gripping surface depends from the pull tab. The body of the pull tab attachment in an assembled condition, wherein male and female components are interconnected, may either include faces or a curved surface.

Abstract: A barrier for diverting fish from a water flow channel (42) along which water is to flow, the barrier (45) comprising a generally planar array of fixed upright slats (46) each extending at least the entire depth of the water. The array (45) is set at an angle less than 90° to the initial flow direction, preferably even less than 30°, and each slat is set at an orientation so as to divert water into a direction other than that through the barrier; the spacing between adjacent slats measured along the array is less than 300 mm. For example the flow channel (42) may branch off from a river (40), the barrier (45) being provided at the mouth of the channel (42) so that the barrier is oriented substantially parallel to the flow in the river, and the slats (46) may be at say 60° or 30° to the initial flow direction in the river, so as to divert fish and passively-carried objects along past the barrier and on down the river.

Abstract: A method that utilizes both software and combination software and hardware mechanisms to comply with the FCC requirement for an U-NII antenna to be an integral part of the device, while providing CRUable dual mode wireless cards and wireless-ready U-NII devices. Enhancements are made to the system BIOS and Device Driver, and two new software-implemented utilities are provided to create authentication schemes that verify and authenticates the CRUable dual mode U-NII radio and antenna combination as being an FCC approved unique coupling during operation of the system. The system boots with only ISM transmission capability and is allowed to complete a U-NII transmission request only with an approved U-NII radio-antenna combination.

Abstract: A yarn carrier (30) for presenting a selected yarn (16) to a pair of gripper jaws (26,28). The yarn carrier (30) includes a yarn guide passageway (14) defining a path along which the selected yarn (16) is longitudinally guided. The passageway (14) has a yarn inlet end, a yarn outlet end and adjacent to the yarn outlet end yarn guides (32) to constrain the tail of the yarn (YT) against lateral deflection in a longitudinal direction of the yarn carrier (30). The yarn guides (32) are depressible on contact with open gripper jaws (26,28) to enable the gripper jaws (26,28) to grip the yarn tail (YT).

Abstract: A method to assess and predict pressurized water stress corrosion cracking in operational nuclear power plants and the effect of adding zinc compounds into a reactor coolant system of the nuclear power plant.

Abstract: A method that utilizes software means to meet the FCC requirement for an U-NII antenna to be an integral part of the device in which it operates, while providing wireless ready U-NII devices and CRUable U-NII radios. Enhancements are made to the system BIOS, including the inclusion of a table of PCI IDs and secret key pairs. The CRUable radio includes a pair of validation registers (VRs) and an EEPROM storing an PCI ID and secret key of an approved device. During boot up of the device, the PCI ID and secret key from the device's BIOS are compared against the PCI ID and secret key stored in the radio's EEPROM. The first comparison completes a radio-to-device authentication in the device, while the second comparison completes a device-to-radio authentication in the radio. U-NII transmission capability is enabled only when both parameters match, indicating FCC approved device-antenna-radio combination under the “integral” requirement.

The end shape includes an irregular part polygon having an end point coinciding with the endpoint of the notional part circle, and wherein junctions between one or more adjacent facets of the polygon lie outside the notional part circle and a part of one or more facets lie inside the notional part circle.

Abstract: A method of cutting an elongate timber web is disclosed which forms on each of two opposed ends thereof a tapered end shape including a series of at least four cuts at successive angles to approximate an arcuate convex end. The method includes the steps of performing first and second passes of the web through a saw having cutter groups at adjustably spaced apart locations, each cutter group having at least two cutters set to angles so that the cutters of each cutter group correspond to a subset of said series of cuts at a respective end of the web. The web is rotated between the passes, the rotation between passes and the cutter settings together result in a multi-faceted end cut.
