Title: Method for producing calcium chloride scales and a use of the method
Inventor: HOYER FRIEDRICH
IPC: B01J2/24
Filed: 1998-02-04
Abstract: In the method, calcium chloride scales (75) are produced on a cooled surface (20), namely through the application of a layer (70) consisting of an aqueous CaCl2 solution (7) to the cooled surface, solidification of the layer and stripping off the solidified layer. The solution contains less than 70 % CaCl2 by weight, preferably less than 65 % CaCl2 by weight. The layer thickness is set to a maximum of about 1 mm. A relative speed between the point of application of the solution and the cooling surface is produced so that a specific production rate of at least 20 g/s m2 is connected with this relative speed. The heat is carried off so rapidly through the cooling surface that the solidified layer remains largely free from calcium chloride dihydrate, CaCl2~2H2O. Dry scales thus arise.

Title: Yarn supply apparatus for elastic yarns
Inventor: PARK GERHARD
IPC: D04B15/50
Filed: 1996-09-17
Abstract: A yarn supply apparatus for elastic yarns in knitting machines with chronologically very severely fluctuating and periodically high yarn consumption has been created that is embodied as a feed wheel mechanism. The yarn supply apparatus has a yarn wheel, around which the yarn to be supplied is wrapped a few times, and which furnishes the yarn to a yarn store located between the knitting machine and the yarn wheel. The yarn store is embodied as an essentially rectilinear segment of the yarn path. To monitor the yarn tension, a voltage sensor is provided whose measurement path is vanishingly short in comparison with the length of yarn to be stored in the yarn store. The measurement path is defined by a movable element of the sensor device and is oriented orthogonally to the travel path. The combination of a low-inertia drive device, which has a yarn store that utilizes the intrinsic elasticity of the yarn, and a closed-loop controller that monitors the yarn tension by means of a sensor device makes it possible to use the yarn supply apparatus for supplying elastic yarns and to keep the yarn tension essentially constant even when the demand for yarn fluctuates severely over time.      Now that the yarn in the yarn store is not subject to deflection and in particular is not subject to significant friction, and now that the yarn reaches the yarn wheel without the interposition of a yarn brake, even short returns of yarn from the knitting machine to the yarn supply apparatus can be intercepted by briefly rotating the yarn wheel in reverse.

Title: A packet-switched-network telephone system
Inventor: PICARD DONALD F
IPC: H04L12/56
Filed: 1998-07-31
Abstract: A telephone system is disclosed establishing a link over a packet-switched-network, such as the Internet, between two telephone interfaces by exchanging network addresses.  The addresses can include ATM addresses to allow a virtual connection to be established between the interfaces.  The interfaces exchange speech data packets of speech signals from a called party telephone and a calling party telephone over the network.  An interface converts the speech signals of the parties into the speech data packets. The system dynamically allocates network and interface resources to complete the telephone call transaction.  The system provides a number of enhanced calling services not normally available to PSTN subscribers including: message-delivery, call-back, call-screening, network-camp-on, call-back-from-queue, find-me, meet-me-pager, call-forwarding, call-interrupt, call-waiting, business-dialing, automatic-call-distribution, virtual-automatic-call-distribution, speed-dial, call-transfer, conference-calling and network-administration.  Echo cancellation is used to eliminate echoes caused by PSTN circuits associated with the telephones.  Silence detection is used to improve network efficiency by not sending packets when the parties are not speaking.  The delay  in the packet-switched-network is used to adjust the size of sound segments formed into a packet. The interfaces allow the system to provide end points in a packet-switched network that manage a telephone call over the packet switched network.

Title: Communication system comprising lightning protection
Inventor: KORNBLIT AVINOAM
IPC: H05K9/00
Filed: 1998-08-11
Abstract: At least the power portion of the transmitter and the front end of the receiver of base station of a wireless communication system (70) are advantageously co-located with the antenna (or antennae), typically atop a tower or other elevated feature. Such co-location however exposes the electronics to lightning damage. This is avoided by placement of the electronics and antenna (101) into lightning protection apparatus that is transparent to rf radiation during lightning-quiescent conditions but is a Faraday cage during a lightning strike, reverting to the transparent condition at the conclusion of the strike. This is achieved by placement of the electronics and antenna inside a housing that comprises a dielectric chamber (11, 12) filled with ionizable gas in contact with electrodes (14, 15) selected such that, during a lightning strike, current can flow between the electrodes.

Title: Search optimization system and method for continuous speech recognition
Inventor: STUBLEY PETER R
IPC: G10L15/19
Filed: 1998-11-04
Abstract: A system and method for continuous speech recognition (CSR) is optimized to reduce processing time for connected word grammars bounded by semantically null words. The savings, which reduce processing time both during the forward and the backward passes of the search, as well as during rescoring, are achieved by performing only the minimal amount of computation required to produce an exact N-best list of semantically meaningful words (N-best list of salient words). This departs from the standard Spoken Language System modeling which any notion of meaning is handled by the Natural Language Understanding (NLU) component. By expanding the task of the recognizer component from a simple acoustic match to allow semantic information to be fed to the recognizer, significant processing time savings are achieved, and make it possible to run an increased number of speech recognition channels in parallel for improved performance, which may enhance users perception of value and quality of service.
