Abstract: L'invention concerne une pile (12) zinc-nickel à débit élevé présentant une électrode positive (14) en hydroxyde de nickel, une électrode négative (16) en zinc, un électrolyte alcalin, et un séparateur (20) microporeux. Ladite pile est structurée comme une pile bipolaire. Un collecteur de courant (22) est pourvu de l'électrode positive sur un de ses côtés et l'électrode négative sur l'autre côté. L'électrolyte est en contact avec au moins l'électrode positive et l'électrode négative et est contenu dans le séparateur. Ledit collecteur de courant comprend un substrat en cuivre, en feuilles, en contact avec ladite électrode négative en zinc. Un substrat (24) en nickel, en feuilles, est stratifié à proximité du collecteur de courant en cuivre, en contact avec l'électrode positive en hydroxyde de nickel. L'électrode positive en hydroxyde de nickel est appliquée dans un film mince en face du substrat en nickel, en feuilles, éloigné du collecteur de courant en cuivre. Généralement, la capacité ampère heure de l'électrode négative en zinc est 5 fois plus longue que celle de l'électrode positive en hydroxyde de nickel.

IPC: H04H20/00
Filed: 1990-03-16
Abstract: A digital radio transmission system having a first terminal office (10), a second terminal office (20) and at least one drop/insertion (DI) office (30) located therebetween.  Long distance lines between the first and second terminal offices are handled in the DI office together with first and short distance lines each being replaced by first and second protection lines, respec-tively.  A protection line for the long distance lines is realized by commonly using the first and second protection lines inherently allotted to the first and second short distance lines.  Further the line switching, due to a fault in the long distance line, from the faulty long distance line to the both the first and second short line side protection lines can be achieved by communicating a particular line switching control signal among all the offices.

Title: Multiplexed surface acoustical wave apparatus
Inventor: MCCOLL JAMES R
IPC: B60R16/02
Filed: 1990-07-16
Abstract: ABSTRACT OF THE DISCLOSURE      An apparatus is featured for controlling remote devices.  The status or one or more switches associated with remote devices may be transmitted along a single transmission line.  One end of the transmission line contains a surface acoustical wave (SAW) delay line.  The SAW delay line responds to as interrogation pulse of radio frequency electromagnetic energy with a series of delayed pulses, each of which transmits the status of a switch by means of the presence or absence of the pulse.  The SAW delay line and switches are completely passive, requiring no power source.  The transmission line may optionally be interrupted and coupled by means of a pair of inductive coils.  This offers the potential for rotation, as within a steering column of an automobile, without wear or damage to the transmission line.  The other end of the transmission line contains electronic circuitry to provide the interrogation pulse, to decode the return delayed pulses, and to drive other circuitry as required by the switch positions.

Inventor: LE BIHAN DENIS
IPC: H04L12/54
Filed: 1990-10-11
Abstract: The incoming cells of a input asynchronous time-division multiplex channel (mtr) are counted by a counter (FFB) assigned to each virtual circuit which is incremented on each incoming cell of the virtual circuit and decremented periodically. Clock signals define consecutively numbered cell times (ntc). Queue and chaining table (FAVE, FCVN) define a cell time queue (FAF, FAL, FAV) specific to each of the cell times, a virtual circuit being assignable to a cell time by writing its identifier into the corresponding cell time queue. A controller (MC) uses the content of the cell time queues (FAF, FAL, FAV) and, for each cell time, identifies a virtual circuit to be processed and decrements the counter (FFB) belonging to this virtual circuit. The controller further includes arrangements whereby any virtual circuit whose counter is not idle is assigned to one of the cell times to be decremented by virtue of the arrival of this cell time.

Title: Apparatus and method for dispensing detergent in a warewash machine
Inventor: REINHARD ROGER A
IPC: A47L15/44
Filed: 1991-01-15
Abstract: A dispensing apparatus and method for dispensing detergent in a warewash machine. The rinse water spray system or an alternate water source is monitored to determine if water is being supplied to the warewash machine. Once water is sensed being supplied to the machine, the apparatus determines whether the water is being supplied for a rinse cycle or a fill cycle. The amount of detergent dispensed is controlled based upon the determination of whether the water is being supplied in a rinse cycle or a fill cycle. If the apparatus determines that the water is being supplied for a rinse cycle, a make-up amount of detergent is dispensed upon completion of the rinse cycle. If the apparatus determines that the water is being supplied for a fill cycle, the washtank is pre-charged with the desired concentration of detergent during the fill cycle.
