Abstract: Under the present invention, componentized costs for providing/producing an item are collected from a plurality of suppliers. The componentized costs include the fixed and variable costs associated with raw materials and production for providing the item according to various specifications and order quantities. When a buyer wishes to obtain the item, a particular order specification and a demand forecast for the item will be provided. Based on the particular specification, the demand forecast and the componentized costs, an optimal order quantity for the item will be calculated. Then, a total (lifetime) cost for providing the item will be calculated for each supplier. The supplier having the lowest total cost for the projected lifetime of the item will be identified to the buyer.

Abstract: Removable filter cartridge assemblies (10) for housings (28) having a removable member (101, 130) to provide access to the interior (102, 136) of the housing and an inlet (108, 134) and an outlet (109, 135) to and from the interior thereof (102, 136) comprising at least one filter cell (12) through which fluids are passed for filtration, the cell having a central aperture (18) therethrough for the passage of fluid, separate from the fluid within the housing; opposed disks of filtration media (16), spaced apart and defining upper (16U) and lower (16L) surfaces of the cell emanating radially from the central aperture; and, an outer peripheral edge (14) circumscribing the cell; first and second retainer ring members (22) securably disposed on the upper and lower surfaces of said filter cell, open to and concentric with the central aperture, said first retainer ring members being contiguous with the outlet of the housing; and lifting means (42, 50, 80, 90) communicable with one of the retainer ring members for mo

Abstract: Filter cartridge assemblies (10) comprising at least one filter cell (12) having an aperture (18) therethrough; a retainer ring (22) securably disposed on the filter cell and concentric with the aperture; and a lifting device (42, 50, 70, 80, 90) in communication with the retainer ring. A device for lifting and carrying a filter cell (12) comprising a retainer ring (22); and a lifting device (42, 50, 80, 90) in communication with the retainer ring. A method for the assembly of a cell-type filter cartridge device (10) comprising the steps of providing a filter housing (28) for at least one filter cell (12), the filter housing having a removable opening, an inlet and an outlet; providing at least one filter cell, the cell having an aperture (18) communicable with the outlet and a retainer ring (22) secured to the cell and providing a lifting device (42, 50, 80, 90); depositing the filter cell into the filter housing; and fastening the removable opening to the filter housing.

Abstract: An apparatus for the detection and recording of the presence of a filament or other small object at a station (13) is described. The apparatus includes light beam detection means (70, 71) and means (14) for rotating the object at the station so that the object interrupts the light beam as it is rotated and is detected and recorded by a counting means (102, 108, 110). The apparatus is particularly useful for the detection of filaments and other small objects which cannot be positioned precisely at the station. The apparatus is specifically useful for detecting roots or shoots (201) resulting from seed (200) germination in a tube (11).

Abstract: An improved magnetic tape test article includes a plurality of longitudinally spaced-apart test sections. Some of the test sections are repeated to facilitate recorder tests under different tape wrap conditions. One of the tests is a compound test enabling several simultaneous measurements of several parameters of the recorder. The tests are particularly adaptable for helical scan digital signal recorders. The tests measure parameters such as head to medium spacing, tracking (skew, servo offset and the like), readback circuit performance, including clocking, phase tolerances, error detection and correction operations, response to dropouts, resynchronization response and amplitude tolerances. Profile of the spacing between the record medium and the head is measured over the length of the recorded path around the cylindrical mandrel.

Abstract: A method and apparatus for controlling a chemical reaction by heterogeneous catalysis, in which a surface acoustic wave (SAW) is propagated along a surface of a piezoelectric element in contact with liquid or gaseous substances to be chemically reacted, to thus generate an electric field at the surface of the element which initiates and sustains the desired reaction. The catalysis rate can be varied by varying the frequency and/or intensity of the surface acoustic wave. The surface of the element may be coated with a very thin film of a catalytic group 8 metal which can be penetrated by the SAW electric field. In such an embodiment, normal catalysis proceeds via chemisorption, and the SAW element field acts to increase the catalysis rate.
