Abstract: A method concerning measurements by using an electrode array comprising three electrodes for central nervous system (CNS) monitoring from the forehead of a patient's head. A first electrode of said three electrodes is positioned between the eyebrows or immediately above the eyebrows of the patient. A third electrode of said three electrodes is positioned apart from the first electrode on the hairless fronto-lateral area of the forehead the patient. A second electrode is positioned between the first and the third electrodes on the forehead of the patient.

Abstract: A level detector comprises an array of light emitting devices mounted in a line parallel to an array of light receiving devices, the arrays being mounted within a housing capable of internally reflecting light from the emitting devices to respective receiving devices unless the respective parts of the level sensor are immersed in liquid. The outer internally-reflecting surface of the housing is preferable a continuous straight-line surface along the direction parallel to the arrays.

Abstract: The present invention provides a method of making a laminated, gathered, elastic web. The method includes the steps of feeding a first substrate in a machine direction, feeding a second substrate aligned with the first substrate in the machine direction, and feeding an array of elastomeric strand material between the first and second substrates in such a manner that the elastomeric strand material is stretched in the machine direction and aligned with the first and second substrates. A hot melt pressure sensitive adhesive, such as a styrene-isoprene-styrene based adhesive, is applied to one substrate, and a curable adhesive, such as a polyurethane based adhesive, is applied to the other substrate. Thereafter, the two substrates and the elastomeric strand material are compressed to form a laminate elastic web while maintaining the elastomeric strand material in its stretched state. Machine direction tension is maintained on the laminate until the hot melt adhesive cools and bonds the layers together.

Abstract: An aquarium base is provided by a base member (26, 26a) extending horizontally around a periphery generally coextensive with the periphery of the aquarium tank (22, 22a, 22b), the base member having a lower surface (30, 30a) resting on a horizontal support surface (28), and an upper surface (32, 32a) upon which the aquarium tank rests. The base member has a peripheral skirt (34, 34a) extending generally vertically between the upper and lower surfaces and around the periphery. The peripheral skirt has an upper extension (36, 36a) extending upwardly from the upper surface vertically along and adjacent and outward of the aquarium tank. The peripheral skirt has a first periphery (72, 72a) at the lower surface, and a smaller second periphery (74, 74a) at the upper surface.

Abstract: A filter (110) is provided with a fixture (70) having a first set of axially extending inner pillars (72, 74, 76, 78) defining a first cylinder (80) along inner bend lines (34) of inner pleat tips (32) of an annular pleated filter element (22), a second set of axially extending outer pillars (82, 84, 86, 88) defining a second cylinder (90) extending along outer bend lines (38) of outer pleat tips (36) of the filter element (22), inner and outer circumferential rings (92 and 94) extending around the respective first and second sets of pillars and circumferentially spacing and supporting such pillars, and a plurality of radial spokes (100, 102, 104, 106) at an axial end (98) of the fixture (70), each spoke extending radially between a respective inner and outer pillar and radially spacing and supporting respective inner and outer pillars in radially spaced concentric relation defining a reception annulus (108).
