  • Patent number: 6438602
    Abstract: A method of selectively establishing any one connection of several different types, between a client program in a first computer and a server program in a second computer, includes the following steps. Initially, a control program is provided in the first computer which receives a command with parameters, from the client program, that specify the one type of connection which is to be established. In response, the control program automatically constructs a particular pipename which includes the parameters in a format that differs for each different type of connection. Thereafter, the control program tranmits the pipename which it constructed to a communications program in the second computer. Subsequently, the control program receives a result from the communications program which indicates whether or not the communications program used the pipename to successfully establish the one type of connection to the server program. Then, the control program notifies the client program of the result.

  • Patent number: 6338277
    Abstract: A flowmeter for a medium includes two transducers displaced from each other in the direction of flow of the medium. The flowmeter contains an emitting device which emits acoustic signals in both directions through the medium using the transducer. The flowmeter also contains a processing device for determining information via the flow of the medium by monitoring the travel times of the acoustic signals received by the transducers. A part of the space between the transducers defines a flow path which includes a flow structure with at least one medium flow passage extending axially in the direction of the flow of the medium. The medium flow passage has damping devices which are located so that at least one asymmetrical noise propagation mode is damped. The damping device has a damping structure which extends substantially across the whole length of the media flow passage.

  • Publication number: 20010043352
    Abstract: A flexible and extensible virtual printer architecture is provided. According to one aspect of the present invention, a mechanism is provided for driving multiple heterogeneous presentation devices. A presentation job is received on behalf of a presentation device, the presentation job includes a data stream which contains source data in the form of text, image, graphics, and/or other embedded objects. The source data is then reduced to an intermediate format. Based upon the intermediate format and control information associated with the data stream, device-specific data and device-specific control information are generated for the presentation device. Finally, the presentation device is driven by providing the device-specific data and device-specific control information to the presentation device.

  • Patent number: 6114120
    Abstract: A new class of nucleic acid compounds, referred to as nucleic acid ligands, have been shown to exist that have a specific binding affinity for three dimensional molecular targets, including cell surface macromolecules. The nucleic acid ligands are identified by the method of the invention referred to as the Systematic Evolution of Ligands by EXponential enrichment (SELEX), wherein a candidate mixture of nucleic acids are iteratively enriched and the high affinity nucleic acids are amplified for further partitioning. The high affinity nucleic acid ligands are useful in capturing target cells.

  • Patent number: 6041955
    Abstract: A bulkhead assembly, for use with a cargo container (10) within which is provided a liner (15) for the bulk transport of flowable materials, has a plurality of elongate members (20) which extend upwardly from the floor (11) of the container, but with a central region (25) adjacent the container floor (11) free from obstruction. A flexible sheet (26) is folded to form two overlying layers (27, 28) joined together to define pockets in which are positioned two pairs of rigid plates (29, 30), the inner pair of plates (29) being spaced apart. In use, the sheet (26) is arranged adjacent the container floor, so as to extend over the central region (25), and also to provide corner fillets for the container, the lower region of the liner when in use being supported by the sheet (26) and the plates (29, 30).

  • Patent number: 5886355
    Abstract: Ion implantation equipment is modified so as to provide filament reflectors to a filament inside of an arc chamber, and to remove the electrical insulators for the filament outside of the arc chamber and providing a means of shielding, thereby reducing the formation of a conductive layer on said insulators and greatly extending the lifetime and reducing downtime of the equipment. The efficiency of the equipment is further enhanced by means of an interchangeable liner for the arc chamber that increases the wall temperature of the arc chamber and thus the electron temperature. The use of tungsten parts inside the arc chamber, obtained either by making the arc chamber itself or portions thereof of tungsten, particularly the front plate having the exit aperture for the ion beam, or by inserting a removable tungsten liner therein, decreases contamination of the ion beam. Serviceability of the arc chamber is improved by means of a unitary clamp that separately grips both the filament and filament reflectors.

  • Patent number: 5783778
    Abstract: A cable locking and sealing device has an elongate body of elastomeric material formed with at least one through-passage for receiving a cable and at least one longitudinal slit extending down at least a portion of its length. The interior of the through passage is formed with a series of annular ribs which each taper in depth towards a point adjacent the longitudinal slit. When the device is pulled into an entry port, its elongate body becomes radially compressed thereby holding the cable firmly in place: however, the sealing effect of the ribs against the cable is not compromised by any relative longitudinal displacement of the portions of the body either side of the slit.

  • Patent number: 5706347
    Abstract: A method and system for verifying the identity of a computer network node is provided. As part of the session initiation process between two partner nodes planning to exchange sensitive encrypted data, the node receiving data generates and encrypts a session key which is transmitted to the node sending data. At the sending node, the low order four bytes of the encrypted session key are saved for authentication of the receiving node. The encrypted session key is returned to the receiving node as session set-up continues. The receiving node concatenates the low order four bytes of the encrypted session key with four bytes of pseudorandom data to form an initial chaining value which is then encrypted and transmitted to the sending node. The sending node recovers the initial chaining value and compares the low order four bytes of this value with the low order four bytes of the encrypted session key previously saved. If the values are the same, authentication of the receiving node is established.
