Title: Pipe coupling
Inventor: WEINHOLD KARL
IPC: F16L19/03
Filed: 1998-03-27
Granted: 2007-12-11
Abstract: The invention relates to a pipe coupling comprising a socket component and an insert component which is partially insertable to securely fit into the socket component. A ring groove between the socket component and the insert component is sealed by a ring seal. The socket component is releasably connected to the insert component by means of a union nut which contacts a shoulder of the insert component rearwardly for joined movement into the closed position. The union nut is screwed onto the socket component along a cylindrical and/or conical exterior thread. The ring gap between the union nut and the insert component is sealed. The ring gap between the union nut and the socket component is also sealed. The thread connection between the socket component and the union nut is positioned between the two sealing positions.

Title: Method and device for monitoring the thickness of continuously conveyed flat objects
Inventor: HAENSCH EGON
IPC: B41F33/00
Filed: 1998-08-14
Granted: 2007-07-31
Abstract: For monitoring the thickness of printed products (1) which are conveyed by one conveying means each in a continuous conveying stream with a conveying direction (F), monitoring elements (4) are introduced into the conveying stream and one monitoring element is allocated to each printed product. The monitoring elements (4) substantially consist of a pair of monitoring levers (10, 11) with clamping jaws (13) which are pressed against each other with a clamping force. For the monitoring, a region of each printed product (1) is clamped between the clamping jaws (13) of a pair of levers (10, 11) which are pressed against each other. Pairs of one monitoring element (4) and one printed product (1) interacting with each other by clamping are conveyed in succession through a monitoring area. For quantitative recording of this interaction, an image is recorded of one edge of each of the monitoring levers (10, 11) of one lever pair and of the distance (D) between these edges (30), which distance depends on the thickness of the pressed printed product (1). From this image a measured value corresponding to the distance (D) is determined. The measured value is compared with a reference range allocated to each monitoring element (4). The reference range is constituted by a reference value determined by calibration and a predetermined tolerance range, whereby a calibration is carried out for each control element (4) using a product with a known, i.e. correct thickness.

Title: Thermoplastic resin coated aluminum alloy sheet, and method and apparatus for production thereof
Inventor: SHIMIZU KEIICHI
IPC: B32B15/08
Filed: 1997-03-24
Granted: 2005-06-28
Abstract: A thermoplastic resin coated aluminum alloy sheet has excellent processing adhesion and high adhesion after retort processing such that laminated thermoplastic resin layers do not peel off even when the alloy sheet is subjected to severe processing such as stretching after deep drawing and furthermore, ironing. A production method and a production apparatus for the alloy sheet are also described. A treatment by an alkaline solution and a treatment by an acidic solution are sequentially applied to bring the surface of an aluminum alloy sheet into a specific surface state and then electrolytic chromic acid treatment is carried out by a known method so as to laminate a thermoplastic resin to an aluminum alloy sheet having a two-layered film which comprises metallic chromium as the lower layer and a chromium hydrate as the upper layer and has a specific surface condition. As a result, a thermo-plastic resin coated aluminum alloy sheet having excellent processing adhesion capable of withstanding molding and processing can be obtained.

Abstract: A postage metering system includes a plurality of printer modules connected as part of a network and operating as clients on the network. Postal security devices (PSDs) are coupled the clients. Each PSD is local to the coupled client functioning as a host to the PSD and remote to the other of the plurality of clients. The PSD includes unique identification, postal value storage and a digital signature generator. The clients function as a postage metering network wherein a client requests evidence of postage payment from a remote PSD for concluding postage metering transactions. Each of the clients determines which of the remote PSDs are available for metering transactions on the network by broadcast messages and requests. In one embodiment, a broadcast request for the identity of remote PSDs whose host is logged onto the network is sent over the network by a client when the client logs onto the network. Additional broadcast requests are periodically sent over the network by the client to other clients logged onto the network. Broadcast messages indicating the unique identification of the PSD coupled to a host are sent over the network by the host when the host logs onto the network. Additional broadcast messages are sent periodically over the network by the host. Another broadcast message indicating that a PSD is no longer available is sent over the network by the host when it logs off the network. In alternate embodiments a network server controls broadcast requests and messages.

Abstract: An asymmetric optical fiber Mach-Zehnder interferometer has first and second optical fibers connected at a first coupling region and a second coupling region. The first and second optical fibers form two interfering arms between the first and second coupling regions. To form the asymmetry, the propagation constant in a portion of the first optical fiber in one of the coupling regions differs from the propagation constant in a portion of the second optical fiber in that coupling region. The asymmetric structure provides 30 dB isolation over a greater wavelength span.

Title: Method and apparatus for searching a database of records
Inventor: KRELLENSTEIN MARC F
IPC: G06F17/30
Filed: 1998-04-29
Granted: 2008-01-08
Abstract: A method and search apparatus for searching a database of records organizes results of the search into a set of most relevant categories enabling a user to obtain with a few mouse clicks only those records that are most relevant. In response to a search instruction from the user, the search apparatus searches the database, which can include Internet records and premium content records, to generate a search result list corresponding to a selected set of the records. The search apparatus processes the search result list to dynamically create a set of search result categories. Each search result category is associated with a subset of the records within the search result list having one or more common characteristics. The categories can be displayed as a plurality of folders on the user's display. For the foregoing categorization method and apparatus to work, each record within the database is classified according to various meta-data attributes (e.g., subject, type, source, and language characteristics). Because such a task is too much to do manually, substantially all of the records are automatically classified by a classification system into the proper categories. The classification system automatically determines the various meta-data attributes when such attributes are not editorially available from source.

Title: System and method for mobile assisted admission control
Inventor: PERSSON HAKAN
IPC: H04W48/12
Filed: 1998-09-15
Granted: 2008-04-15
Abstract: A system for inhibiting the transmission of an access request message from a mobile station when either the system is incapable of granting access at the class of service desired by the mobile or access by the mobile at that class of service would increase the interference level of the target base station or a neighboring base station past its interference capacity. In one embodiment, each base station broadcasts a maximum data rate access parameter and any mobile receiving that parameter and seeking access at a greater data rate refrains from transmitting an access :request message. In another embodiment, each mobile calculates from its path loss to the base station the power level it must transmit in order to gain access as well as the effect of that transmission on the interference level of both the target base station and neighboring base stations. If transmission at the required power level would increase the interference level of any base station past its maximum capacity, the transmission is inhibited. The system is most effective in CDMA mobile cellular radio systems.
