Abstract: A multilayer analytical element has been prepared for use in the accurate colorimetric determination of lithium ion found in aqueous specimens. The element includes first and second reagent layers underneath a porous spreading layer. A more precise assay at longer read times of dye formation and reduced rate of background dye development are achieved because the second reagent layer contains both an aromatic phenol organic solvent and a perfluoroalkyl surfactant which were formerly included only in the first reagent layer. A 14-crown-4-ether derivative dye is used to complex with lithium ion to provide the colorimetric signal. <IMAGE>

Patent JP-H0322804-B2 (JP)
IPC: F02F11/00
Filed: 1984-09-03
Abstract: A method of making a gasket by pressing particles of expanded graphite in a mould onto the opposed faces of an apertured reinforcement plate to compact the particles and unite them with the plate makes use of a mould assembly comprising a base plate, first and second moulding rings, and a moulding punch which is apertured to conform with the apertures of the reinforcement plate. The first and second moulding rings are positionable above the base plate to form lower and upper mould recesses, into which expanded graphite is successively charged, so enclosing the apertured reinforcement plate. The punch is then operated to compact the graphite particles and unite them with the reinforcement plate. Compaction in the mould assembly can produce either the finished gasket or at least a composite whose graphite layers are firm enough to be handled outside the mould assembly to permit further compaction. The method is specially applicable to the manufacture of cylinder head gaskets for internal combustion engines.

Abstract: A wheel load sensor (10), which is intended for building into a recess in the surface of a roadway for the selective detection of the vertical directional component of a pressure proceeding from a wheel load simultaneously comprises a piezoelectric measuring element (11), a conductor functioning as an inner electrode (12), and a hollow conductor (13') as outer electrode which, to fix a measurement axis necessary for the selective directional detection, clamps wall sections (16), running approximately parallel to the plane of the road surface, of the piezoelectric measuring element, while the remaining wall sections (16') of the piezoelectric measuring element are accommodated in the hollow conductor (13') at a distance from its other wall sections. In the built-in position, the measurement axis, which coincides with the clamping axis (P), is aligned perpendicular to the surface of the road surface. Since the wall sections (16') which are spaced apart from the hollow conductor (13'), of the piezoelectric measuring element (11) lie approximately transversely to the measurement axis, the transmission of horizontal pressure components of incoming pressure waves to the piezoelectric element (11) is largely avoided. <IMAGE>

Abstract: Vibration dampener and stiffener apparatus (210, 450, 470) and method for increasing the dampening and the stiffness of a tube (200) subjected to large amplitude flow-induced vibration. The preferred embodiment of the apparatus (210) includes a plurality of flexible braided cables (210) capable of being disposed in the tube (200) for dissipating the vibration energy of the tube (200) as the tube (200) vibrates, the cables (210) having a first end portion (280) and a second end portion (290). Enclosing the first end portion (280) of the plurality of flexible cables (210) is a rigid cable tip member (310) and enclosing the second end portion (290) of each cable (210) is a rigid cable end fitting (380, 410). As the tube (200) vibrates due to flow-induced vibration, the vibration energy will be transferred to the cables (210) which will rub together creating frictional heat energy that will radiate from the cables (210). In this manner, the vibration amplitude of the tube (200) is decreased. Moreover, as the tube (200) vibrates, the rigid cable tip member (310) and the rigid cable end fittings (380, 410) will tend to stiffen the tube (200).
