Abstract: A watthour meter mounting apparatus, such as a socket, socket adapter and the like, has a safety shield completely enclosing the jaw contacts of the apparatus. Slots are formed in the safety shield to allow the insertion of a watthour meter blade terminal therethrough into connection with the jaw contacts.  In one embodiment, a socket adapter housing includes front and back plates which are joined together and form a cavity therebetween in which the jaw terminals and the electrical conductors are disposed.  Raised receptacles formed in the first plate loosely receive the jaw contacts mounted on one end of the conductors.  In another embodiment, an insulating housing is mounted over the jaw contacts in a socket or socket adapter, with slots formed in the housing to allow the insertion of a watthour meter blade terminal therethrough into a jaw contact disposed within the housing.  The housing may be formed with one large cavity surrounding all of the jaw terminals or a plurality of separate receptacles, each surrounding at least one jaw contact.  The conductors may be formed of rigid bus bar for increased current carrying capability.  Each jaw contact can be formed of separate contact clips biased toward each other by separate spring clips riveted to one end of each conductor.  A terminal slidably receives the other end of each conductor as well as a line/load external conductor.

Abstract: An apparatus and method for producing mail pieces. The apparatus includes a first printer for printing documents and a second printer for printing envelopes and a mail finishing unit for receiving the printed documents from the first printer and the envelopes printed with corresponding addresses from the second printer and inserting the documents into the envelope to form a mail piece. The apparatus operates under the control of a single stream of job data from a host computer, where the job data includes a job header defining default mail piece attributes and mail piece records which include document data and address data, and which may include specific mail piece attribute data for each corresponding mail piece. The apparatus control mechanism partitions the data stream and controls the first printer to print the documents while controlling the second printer to separately print the envelopes which are moved along a separate path to an insert station where the mail piece is formed. Preferably the second printer is an ink jet printer and the apparatus includes a drying buffer to allow time for the printed addresses to dry, and accordingly the apparatus prints several envelopes to load the drying buffer before beginning to print the documents.

Granted: 2000-02-15
Abstract: A molten carbonate high temperature fuel cell contains a hydrocarbon-containing fuel reforming catalyst on a support.          The catalyst is produced by reducing a catalyst precursor which is prepared by intimately mixing a defined Feitnecht compound with a non-calcined alumino-silicate clay mineral and at the same time and/or subsequently but prior to calcination with at least one added stabilising additive for reducing silicon-species loss comprising an alkaline earth and/or rare earth  metal  compound,  and,  optionally,  an  alkali  metal compound, and thereafter calcining the intimate mixture.  The catalyst has been found to be suitable for the steam reforming of methane at the working temperature of the molten carbonate fuel cell and has been found to be substantially resistant to deactivation in the hot alkali metal carbonate environment.

Abstract: L'invention concerne la possibilité de reprodure des modifications effectuées au niveau d'un site local vers des sites multiples situés à distance dans un environnement d'égal à égal. Les informations concernant ces modifications reproduites (par exemple, insertion, effacement ou mise à jour) sont contenues dans un ensemble de tables de reproduction. De ce fait, des modifications peuvent être dupliquées au niveau d'autres sites immédiatement après la modification originale ou différées jusqu'à disponibilité du site à distance. Les tables de reproduction décrites par l'invention comprennent une table de transaction, une table de noeuds de transaction, une table d'appels, une table de noeuds d'appel et une table d'exceptions. L'invention concerne, de plus, une reproduction de niveau de procédure à orientation logique. La reproduction de niveau de procédure modifie un site à distance sur la base des opérations logiques utilisées pour modifier les données au niveau du site d'origine. La reproduction de niveau de procédure permet d'identifier également des mises à jour conflictuelles. Les informations concernant les conflits identiques par l'invention peuvent être retenues dans les tables de reproduction. Les informations contenues dans les tables de reproduction peuvent s'utiliser immédiatement ou ultérieurement, afin d'adresser tous conflits détectés par l'invention. Celle-ci permet de repositionner toutes modifications effectuées une fois qu'un conflit est identifié. De plus, l'invention permet d'adresser ces conflits à l'intérieur d'un programme d'application. Elle permet d'effectuer une reproduction orientée par lignes. Une bascule électronique associée à une table met en file d'attente les procédures à distance différées. Les procédures à distance utilisent les valeurs anciennes et nouvelles depuis la modification originale, afin de reproduire la modification au niveau de sites à distance et de détecter des mises à jours conflictuelles.

Abstract: A floating row crop cultivator rig is supported behind a rigid guide tire.  A guide wheel standard straddles a bracket which mounts the forward end of a rig parallel bar linkage to a toolbar.  A tool support depends from the aft end of the parallel bar linkage and carries a ground engaging element directly rearwardly of the guide tire.  Instead of a conventional rig tire to control rig depth, an adjustable length member with a lost motion connection controls the lowermost position of the linkage and thus of the tool support while permitting upward movement of the linkage when an obstacle is encountered.  A rod threaded through a trunnion on the tool support has a forward end supported in a slotted bracket on the lower bar of the parallel linkage to adjustably limit the lowermost position of the linkage while permitting the linkage to pivot upwardly against the bias of rig weight and an adjustable down pressure spring arrangement to clear obstacles.  A spring trip standard may supported by the tool support to additionally provide trip protection.

Abstract: An improved antifuse which employs the base-emitter junction of a silicided single polysilicon bipolar transistor. The distance between the base metal and emitter metal is shortened and results from self aligning process steps rather than lithographic steps, resulting in a lower and better controlled programming voltage, programming energy and ON state resistance. Typically the conductive filament formed in the new antifuse is about 0.65 microns long and is formed by a voltage pulse having a relatively slow rise time (e.g. 150 microseconds), resulting in improved properties which provide advantages in circuit design and in manufacturing circuits using the new antifuse.
