Title: Printhead flush and cleaning system and method
Inventor: ENZ RICHARD T
IPC: B41J2/165
Filed: 1999-12-10
Abstract: A system and method are provided for cleaning the printhead of a continuous ink jet printing system. A cleaning fluid is introduced and used to flush ink residues and debris from the interior of the drop generator, the exterior of the orifice plate, the charge plate face and the catcher face. This system and method removes dried ink residues and other debris and deposits by providing a cleaning fluid with a low surface tension to dissolve or flush away the unwanted material from the orifices. This is particularly advantageous in that the flushing and rinsing is accomplished without mechanical contact which could abrade or damage the orifices.

Filed: 1998-07-10
Abstract: The invention, which permits active solder braze technology to be used in a more versatile manner, relates to a solder braze alloy and to a method for joining workpieces by soldering by means of a solder braze alloy. The novel alloy is characterized in that it comprises 1 - 10 % by weight of an element or a mixture of elements of subgroup IVa and/or Va of the Periodic Table of the Elements and 0.1 - 20 wt.  % of an element or a mixture of elements of the group of the rare earths and the remainder consists of zinc, lead, tin, bismuth or indium or a mixture predominantly of two or more of the elements zinc, lead, tin, bismuth and indium and optionally of the elements silver, copper, gallium, antimony, nickel, manganese, chromium, cobalt possibly of customary impurities. The alloy according to the invention can be processed as a solder even in oxygen-containing atmospheres, for example in air, has a relatively low processing temperature and exhibits good wetting even of inherently poorly wettable surfaces such as, for example, ceramic surfaces. In a development of the invention the solder braze alloy can be processed without a flux.

Abstract: A method to determine a physical quantity within a measuring space by means of acoustic transit time measurement uses an acoustic transducer as a transmitter and an acoustic transducer as a receiver. The two functions can also be combined in a single transducer. The acoustic transit time measurement involves a time-dependent comparison between the shape of an acoustic transmitted signal selected at least partly on the basis of the type of signal processing to be used and at least two points in an acoustic received signal and/or a signal derived from that received signal again selected at least partly on the basis of the type of processing to be used. An apparatus for this method could be equipped with an acoustic signal-generating transducer, an acoustic signal detection transducer, a signal processing device which selects measuring points from the signal, and detection algorithm adapted to the shape of the signal.

Filed: 1999-07-01
Abstract: The present invention relates to a method and a device for optimising the transmission safety and the defect tolerance in high-bit-rate data networks using a signal-line redundancy between the nodes of the network. According to this invention, parallel signal lines can be used or switched either as a working line or as a protection line, while a plurality of selectors, bridge circuits and interface modules are provided on the node side of the network.  An interface module is provided at the end of each of the parallel signal lines, and all interface modules are fundamentally in the active state. In case one interface module fails, line defects can be immediately avoided due to the switching of the signalling line and to the redundancy of the interface modules. Error messages can be transmitted between the interface modules of the in-coming and out-going parallel signal lines through an appropriate connection.

IPC: G01N33/576
Filed: 1999-09-28
Abstract: Methods for identifying hepatitis C virus (HCV)-infected subjects responsive  to treatment for HCV infection or unlikely to respond to treatment for HCV infection are described. The level of Th2 cytokines in the subject during treatment serves as an indicator of whether the subject is likely to respond  to treatment for HCV, e.g., interferon treatment. An elevated level of at least one Th2 cytokine during treatment indicates that an HCV-infected subje ct is unlikely to respond to a treatment for HCV. A decreased level of at least  one TH2 cytokine indicates that an HCV-infected subject is responsive to a treatment for HCV. In a preferred embodiment, IL-10 levels are detected to identify subjects responsive to or unlikely to respond to interferon treatme nt.
