Granted: 1995-08-22
Abstract: A diagnostic apparatus for a vehicle network system comprises a multidrop bus for transmitting data for controlling electric loads of a vehicle, and a plurality of nodes connected to the multidrop bus, for controlling the corresponding electric loads of the vehicle, a diagnosis unit electrically connected to two ends of the multidrop bus so that the data is trans-mitted through the multidrop bus therealong in two opposite directions.  The diagnosis unit has a processing block for sending inquiry data to the corresponding nodes from the two ends of the multidrop bus alternately in the two directions, receiving response data from the nodes and detecting from what nodes the response data is received and is not received to locate a portion or portions of the multidrop bus where trouble has occurred.  The detection of trouble in the multidrop bus is made possible when the diagnosis unit is connected to the two ends of the multidrop bus.

Title: Adjustable gas nozzle
Inventor: RIDENOUR RALPH G
IPC: F23D14/48
Filed: 1990-10-11
Granted: 1999-09-14
Abstract: A gas nozzle has a body threaded on a threaded conduit with an insert therebetween. This insert is not changed for another insert in order to adapt the nozzle to either natural gas or LP gas; instead, the body is tightened onto the insert and threaded conduit for LP gas and is loosened about one thread for natural gas. The insert has a first restricted orifice and a bypass passageway around this restricted orifice. The body has a second restricted orifice which is larger than that of the first restricted orifice. Thus, When the body is tightened on the conduit, a seal is made to close off the bypass passageway and the gas flow is through the first and second restricted orifices in series. When the body is loosened, the bypass passageway comes into effect and the gas flow is also through the bypass passageway to be restricted only by the second restricted orifice. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Title: Mail piece weight monitoring system and method
Inventor: SANSONE RONALD P
IPC: G07B17/00
Filed: 1991-11-05
Granted: 2008-10-21
Abstract: This invention relates to a system for and method of determining the accuracy of mail piece weights. The weight of individual mail pieces during a mail run is displayed in real time. A high speed weighing scale is located downstream from the mail processing unit to receive the mail pieces after the mail processing unit has inserted selected materials into envelopes. As each mail piece is weighed, its weight is stored in memory and a display can be made showing all the weights of the individual mail pieces in real time. This display can be temporary, such as on a monitor, or permanent, such as a print out. With such display, an operator has a fast method of determining if the weights are in an expected range.

Inventor: HAAS THOMAS
IPC: C07C47/19
Filed: 1992-11-26
Granted: 1998-05-26
Abstract: This invention relates to a process for the preparation of 3-hydroxyalkanals  having 3 to 12, in particular 3 or 4 carbon atoms, by hydration of the corresponding 2-alkenals with water in a homogeneous phase in the presence of an acid catalyst.  The previously known hydration using mineral acids or carboxylic acids as catalyst results in low volume/time yields and/or low selectivities.  These disadvantages can be avoided by using, as catalyst, a dissolved acid-base buffer which results in a pH of from 2 to 5 in the reaction mixture and the acid component and corresponding base of which are present in a total quantity of from 0.5 to 40% by weight in the reaction mixture.  The preferred buffers composed of a low monobasic carboxylic acid and a tertiary amine can easily be recycled.

Abstract: 'invention est constituée d'une méthode et d'un appareil servant à offrir des services de télécommunication sans fil. Des paires d'émetteurs-récepteurs d'un site cellulaire de communication sans fil sont interconnectées directement. ~ la réception d'une demande de service, un contrôleur affecte une paire d'émetteurs-récepteurs à la prise en charge de l'appel. Si celui-ci est destiné au réseau téléphonique commuté public, un émetteur-récepteur non connecté est connecté à un système de commutation, tel qu'un autocommutateur interurbain, et un convertisseur de protocoles effectue une conversion entre les messages de contrôle d'appel destinés au site cellulaire et provenant de ce dernier, ainsi qu'entre les messages de contrôle d'appel destinés à l'autocommutateur interurbain et provenant de ce dernier. Si le site cellulaire est doté d'antennes directives, une paire d'émetteurs-récepteurs connectés aux antennes directives est sélectionnée pour desservir les stations de l'abonné demandeur et de l'abonné demandé; des émetteurs-récepteurs connectés à une antenne équidirective peuvent être utilisés pour le trafic de débordement et le trafic entre le central interurbain et le site cellulaire. L'avantage résultant est que la sélection de paires d'émetteurs-récepteurs appropriés et la syntonisation des stations mobiles sur les canaux appropriés permet d'éviter les opérations de commutation.
