Granted: 1999-06-08
Abstract: An anonymous trading system (Fig. 1) identifies the best bids and offers (QuoteSubmit, Fig. 3) from those counterparties (WS A1a1) with which each party (WS A1b1, WS A1b2, ... WS A2a2) is currently eligible to deal, while maintaining the anonymity of the potential counterparty and the confidentiality of any specific credit limitations imposed by the anonymous potential counterparty. To that end, each bid or offer (QuoteSubmit, Fig. 3) for a particular type of financial instrument is prescreened by the system for compatibility with limited credit information (for example, a one bit flag indicating whether a predetermined limit has already been exceeded) and an anonymous "Dealable" price (24, 26) is calculated for each of the traders (WS A1b, ...

Abstract: A stacker assembly (10) for receiving generally flat documents, such as mailing envelopes and flats, in on-edge relation and maintaining the documents in upstanding side-by-side stacked relation as they accumulate in the stacker assembly. A receiving station is supported at one end of a horizontal support plate (22) and guides successive incoming documents into stacked relation transverse to the longitudinal axis of the stacker assembly. A stacker plate (44) is supported to engage the forwardmost document in the stack and is movable longitudinally of the stacker assembly in response to accumulation of documents in the stacker. A device in the form of a negator spring (56) and a wedge plate (64) cooperate with the stacker plate (44) in a manner to apply a variable pressure against the documents so as to accommodate both thin lightweight and heavier documents in the stack while maintaining them in upstanding relation.

Abstract: An automated method for modifying a speech signal communicated over a telephone network by applying a gain factor in a telephone set before any side tone is added thereto. The gain factor is a function of a received signal indicative of the background noise at the location of the telephone set. The gain applied may be a function of both the background noise level and the original speech signal. Either a linear or a non-linear (e.g., compressed) amplification of the original speech signal may be performed, where a compressed amplification results in the higher level portions of the speech signal being amplified by a smaller gain factor than lower level portions. The speech signal may be separated into a plurality of subbands, each resultant subband signal being individually modified in accordance with the present invention. In this case, each subband speech signal is amplified by a gain factor based on a corresponding subband noise signal, generated by separating the background noise signal into a corresponding plurality of subbands. The individual modified subband signals may then be combined to form the resultant modified speech signal.

Abstract: Le distributeur automatique de lattes est utilisé en combinaison avec un autre distributeur de lattes similaire sur un convoyeur de planches de bois comprenant une extrémité de chargement et une extrémité de déchargement et étant conçu pour déplacer dans une direction donnée des rangées de planches horizontales. Le distributeur de lattes comprend des colonnes, montées au-dessus de la charpente du convoyeur, pour entreposer les lattes et pour former un empilement de lattes. Les colonnes sont reliées à un moyen de distribution pouvant être actionné pour distribuer une par une les lattes entreposées dans les colonnes sur les planches déplacées par le convoyeur. Le distributeur comprend des pinces mobiles dans une direction verticale et s'étendant au-dessus du moyen de distribution. Ces pinces peuvent être actionnées pour saisir chacune des lattes distribuées par le moyen de distribution et pour déposer la latte saisie sur une des rangées de planches déplacées par le convoyeur. Le distributeur comprend également un moyen de contrôle pour synchroniser la mise en action du moyen de distribution avec la mise en action des pinces, de façon à ce que chacune des lattes empilées dans les colonnes soit déposée précisément et automatiquement sur une rangée correspondante de planches coplanaires déplacées par le convoyeur sous le distributeur de lattes. Le distributeur automatique de lattes a l'avantage de permettre un positionnement rapide, précis et peu coûteux de lattes entre les rangées d'un empilement de planches de bois en vue de leur séchage ou de leur entreposage.

Abstract: A no-clean soldering flux consists essentially of one or more halide-free, water soluble activators in an aggregate amount not exceeding about 5 % by weight of the flux, a water soluble fluorinated surfa ctant in an amount not exceeding about 1 % by weight of the flux, and water. The flux is substantially VOC-free and is particu larly useful in a method of producing soldered printed wiring assemblies with minimal residual ionic contamination, so that pos t-soldering cleaning of the assemblies is unnecessary. The absence of significant amounts of VOC's and the elimination of post-soldering cleaning result in substantial environmental and production-related benefits.

IPC: H04Q3/62

Granted: 1999-03-30
Abstract: In a network of telecommunication switches, a first switch redirects a to-be-covered call to a remote call-covering endpoint served by a second switch,without losing control over the call. The first switch accompanies connection of the call to the second switch with signaling that identifies the call as a coverage call. The second switch responds to the signaling by determining the available status of the remote covering endpoint and signaling the status back to the first switch. If the remote covering endpoint is available, the second switch takes steps to connect the call to the endpoint. If the remote covering endpoint is not available, the first switch disconnects the call from the second switch and proceeds to cover the call to analternative covering endpoint. The net effect is that call coverage works -- from a user viewpoint -- identically across a network of switches as it does on a single switch.

Granted: 1999-03-23
Abstract: A snap lock, top opening package (18) for powdered or granular products. The package includes a liner (80) disposed within the interior compartment of the container. The liner has a front panel (85) and two opposing side panels (84, 86) connected to the front panel, wherein the front and side panels are contiguous with the front (33) and side walls (33, 34) of the container. The liner has a top edge (8) which extends above the portions of the front and side walls below the tear-strip (48).
