Abstract: The present disclosure relates to a replaceable ink container for providing ink to an inkjet printing system. The inkjet printing system is of the type having a receiving station for receiving the replaceable ink container. The receiving station has a fluid inlet and a sealing structure. The replaceable ink container includes a reservoir defining a fluid outlet and a sealing surface proximate the fluid outlet. The replaceable ink container also includes a sealing material contained within the reservoir for wetting the sealing surface to seal defects between the sealing surface and the sealing structure.

Abstract: A method of generating an itinerary using a computer is provided. The itinerary includes nodes that represent a location serviced by scheduled transport services. A specification including a plurality of nodes is received. The specification may be in a specified order. An itinerary is then determined where a first fare is calculated that omits a node in the plurality of nodes received. A second fare is then calculated that includes the node omitted in the first fare. Thus, an itinerary that includes fares for each of the plurality of nodes is calculated; however, a fare is calculated that does not include a node in the plurality of nodes and thus does not adhere to the specified ordering of the plurality of nodes received.

Abstract: A fluid interconnect for a component of a printer is disclosed. The component may, for example, be an inkjet printhead removably attached to a printer and having an ink inlet configured to receive ink from an ink supply. The fluid interconnect has a sealing surface configured to form a seal when contacted against a opposing sealing surface on another component of a printer ink delivery system, and carries a surfactant sealant.

Abstract: An ink jet printing apparatus that includes a springbacked fluid interconnect seal that provides a seal between an ink handling component and an ink pipe that is attached to the ink handling component. The spring-backed fluid interconnection seal more particularly includes a generally conically tapered resilient seal, and a pre-loaded spring configured to axially extend or tension the seal. An exemplary embodiment of the invention includes a groove in the sealing face which allows the use of a liquid sealant. The groove holds the sealant in place through capillary forces, and also by virtue of trough-like shape protects the sealant from being wiped away through mechanical member.

Abstract: Pressure regulating apparatus for ink delivered to an ink-jet print head. The apparatus includes an ink pressure regulating valve that is urged shut by a plurality of coned disk springs that apply a substantially constant force to the valve over the length of its travel. The coned disk springs are also called Belleville spring washers.

Abstract: A machine tool and method for simultaneously boring, facing and back boring three bores in a differential carrier with three tools that rotate coaxially with their spindle axes. Each tool has a first slide at its free end that carries a first cutting insert for back boring a first diameter and then generating a radial face that serves as a bearing seat on the differential carrier. Each tool also has a second slide carrying a second insert for boring a second diameter. The construction, arrangement and movement of the two slides are correlated with each other to maintain the tool in balance during extension and retraction of both slides. In the preferred embodiment the first insert must be retracted when it is advanced into the carrier, extended to back bore and then retracted to generate a radial face. The second insert is at the same location circumferentially of the tool. One insert is retracted while the other insert is extended, and vice versa, to maintain the tool in balance.

Abstract: A rotary internal combustion engine is disclosed which provides a power rotor that rotates about its center on a shaft in a stator housing. The power rotor has spring-loaded sliding vanes seated in diametrically opposed radial slots thereon. The outer ends of the vanes contact the interior surface of the stator housing at all times as they sweep through an arcuate compression and expansion chamber defined therein. Adjacent the stator housing is a housing portion having a cylindrical cavity in which a rotary transfer valve rotates on a shaft. The periphery of the rotary transfer valve which has a sealing contact with the interior surface of the cylindrical cavity has generally U-shaped pockets formed on diametrically opposed portions thereof. A cam wheel assembly is keyed to the shaft of the power rotor and a follower in the form of a timing wheel is keyed to the shaft of the rotary transfer valve.

Abstract: A read-out system for a portable noise dosimeter uses light coupled signals to obtain a noise level read-out display. The light signals are coded to effectively prevent extraneous light signals from causing read-out.
