Title: Liquid containment and dispensing device
Inventor: WALLACE JAMES KENNETH
IPC: B41J2/175
Filed: 1996-04-24
Abstract: An ink containment and dispensing device for an ink-jet printer is provided with a main reservoir in the form of a flexible pouch, which is typically maintained at ambient pressure. The main reservoir is coupled to a variable volume chamber via a one-way valve which allows the flow of ink from the reservoir to the chamber and prevents the flow of ink from the chamber to the reservoir. The chamber is coupled to a fluid outlet, which is normally closed to prevent the flow of outward ink. However, when the ink supply is installed in a printer, the fluid outlet establishes a fluid connection between the chamber and the printer. The chamber is part of a pump provided with the ink supply that can be actuated to supply ink from the reservoir to the printer.      The pump has a linearly acting pumping member and a flexible diaphragm that overlies the pumping member, the diaphragm being impervious to the transmission of oxygen and moisture therethrough to prevent degradation of the ink within the chamber.

Abstract: The apparatus for detecting chemiluminescent light is a component of a luminometer that can be incorporated in a sample analysis system. Such apparatus, also referred to as a fiber optic read-head, includes a fiber optic cable having a light-transmission end that connects to a photon counter of the luminometer. An opposite end portion of the fiber optic cable is divided into a plurality of fiber optic ribbons. Each of the fiber optic ribbons has a light-receiving end. The ribbons are radially arranged such that the light-receiving ends define a cylindrical passageway for accommodation of a sample analysis tube or cuvette. The fiber optic ribbons are maintained in their desired position by a core. The core is housed in an opaque housing that prevents light from coming in or straying out. Thus, any chemiluminescent light emitted from a tube within the core is collected by the light receiving ends of the fiber optic ribbon and transmitted to the light-transmitting end of the fiber optic cable for conversion into electronic data. The read-head can also be used with input light beams that produce fluorescent light, multi-angled light scattering, polarized light and light of predetermined intensity.
