Abstract: ABSTRACT OF THE DISCLOSURE          A transmission control system includes an ATM switching network, terminals and terminal adapters respectively connected to the plurality of terminals. The transmission control system also includes a table circuit registering virtual channels presently formed in the ATM switching network in a management table, and a retrieval part for receiving a communication request from one of the terminals and for determining whether or not the management table registers a virtual channel corresponding to the communication request at present. Data output from the one of the terminals is transferred to a different one of the terminals addressed by the communication request through the virtual channel corresponding to the communication request and corresponding two of the terminal adapters when the retrieval part determines that the management table has the virtual channel corresponding to the communication request.  A virtual channel setting part registers the virtual channel corresponding to the communication request in the management table when the retrieval processor determines that the management table does not have the virtual channel corresponding to the communication request.  Data output from the one of the terminals is transferred to the different one of the terminals addressed by the communication request through the virtual channel registered in the management table by the virtual channel setting part.

Title: Method of protecting an aluminum surface
Inventor: CHAN JIMMY C
IPC: C25D11/18
Filed: 1990-08-13
Abstract: ABSTRACT        A method of providing corrosion protection for a specific aluminum base alloy while at the same time creating an olive drab color in the alloy.   Samples of the aluminum base alloy after being cleaned were placed in a bath containing sulfuric acid.  The reaction of the sulfuric acid with the aluminum base alloy creates a columnar substrate on the surface of the samples.  The samples were removed from the sulfuric acid bath and neutralized in a sodium bicarbonate bath.  Thereafter the samples were placed in a bath containing sodium dichromate and a surfactant.  The surfactant lowers the surface tension sufficiently for the sodium dichromate to flow into the interstices of the columnar substrate to seal the surface from the surrounding environment while at the same time reacting to produce the olive drab color.

Abstract: La technique de transfert d'appels de cette invention est caractérisée par l'utilisation de renseignements sur les canaux de la station de base visée et du terminal d'abonné pour déterminer quel canal de trafic radio sera utilisé pour transférer un appel en cours de la station de base de desserte à la station de base visée.  Les appels sont transférés sur le canal radio qui, parmi un ensemble de canaux étudiés par un terminal d'abonné, contient le plus faible brouillage tel que mesuré par le terminal d'abonné.  L'ensemble de canaux étudiés par le terminal d'abonné constitue un sous-ensemble de tout l'ensemble des canaux assignés au service.  Ce sous-ensemble est formé des canaux qui ont peu de brouillage, tel que mesuré par la station de base visée.  La technique de transfert d'appels fait en sorte que les appels sont traités sur les canaux contenant peu de brouillage du point de vue de la station de base visée et du terminal d'abonné.

Abstract: An active clamp circuit for an inductive load switching circuit includes a zener current control resistor to set the breakdown current in a zener diode of the clamp circuit.  The zener breakdown current is set at a sufficiently high level to ensure that the zener diode is operated at a point beyond its "knee" region and therefore does not generate interfering levels of microplasmic noise (MPN).  The zener current control resistor is provided in addition to a circuit speed control resistor such that there is substantially independent control of the switching circuit operating speed and the breakdown current of the zener diode of the active clamp circuit.

Abstract: Abstract:      The atomization of vaporization of a liquid in a carrier gas stream always creates difficulties, particularly if small mass streams are required to produce a high degree of fineness.      In order to be able to supply only the smallest droplets to the point of use, the sprayed-in collection of droplets is deflected together with the carrier gas stream so that droplets which exceed a maximum size are separated. The separated droplets may be additionally vaporized into the carrier gas stream by means of a heated contact surface.      With this method it is possible to conduct a liquid mist in a carrier gas stream like a gas.

Abstract: METHOD AND APPARATUS FOR MATCHING THE PARTS OF A FILM  ORDER USING AN   OPTICAL CHARACTER READER        Abstract A method and apparatus for checking the correlation between all parts of a photofinishing order includes reading the identification numbers on at least some of the parts of the order using an optical character reader. The method includesprocessing the information received from the optic 1 character reader to compen-sate for the inherent characteristics of optical character readers to misread portions of the numbers and includes a method of filtering misread and nonread information to prevent false alarm conditions in which an apparent mismatch is actually a misread, while minimizing the number of actual mismatches that are allowed through the system without causing an alarm. In one embodiment, a portion of the information is obtained in bar code form and a memory device is loaded with a table of bar code and optical character reader information for each order to maintain correlation between the order parts. The method includes the steps of assigning different error weights to various digits of the identification number and summing the error weights to determine when the sum exceeds a predetermined sum that will trigger an operator intervention alarm.
