Abstract: A brake pipe sensing unit may be used with a universal pneumatic brake control unit of a rail vehicle.  The brake pipe sensing unit includes a control reservoir, an auxiliary reservoir, a three  state  valve,  a  quick  service  valve,  a  brake  pipe transducer and a transmission device.  The control reservoir is used as a volume in which gas under pressure may stored and from which gas  under pressure may be  supplied.   The auxiliary reservoir communicates with a supply port of the universal unit and with a first and a second route of the brake pipe sensing unit.    The three  state valve  has  a  first pilot port  in communication with a brake pipe of the rail vehicle, a second pilot port in communication with the control reservoir, and first  and  second  exhaust  ports  both  of which  connect  to atmosphere.    The  three  state  valve  operates  in  an  apply position, a release position and a lap position depending on the pressure bearing on the first and second pilot ports.  The quick service valve connects within the first route and has a service pilot port in communication with both the auxiliary reservoir and the supply port.  The quick service valve closes the first route  when pressure  at  the  service  pilot port  exceeds  a preselected level.  The brake pipe transducer converts pressure within the brake pipe to an electrical signal.  The transmission device communicates the electrical signal received from the brake pipe transducer to a brake control bus on the rail vehicle.

Abstract: The invention provides a method employing a fuel additive to improve the operation of a pass-through oxidation catalyst over long periods of time with continued catalytic activity and without the undesirable conversion of SO2 to SO3. A pass-through catalyst support is continuously, selectively catalyzed by the combustion of a fuel containing a platinum group metal composition which bums to release the catalyst metal in active form. The effectiveness of the process is attributed to improved combustion in the engine by the catalyst and the treatment of the catalytic oxidizer with active catalyst metal released during combustion such that, in the exhaust system, the soluble organic fraction of the particulates and the levels of gaseous unburned hydrocarbons and carbon monoxide are significantly reduced. The catalysts conditioned by the present invention cause minimal conversion of SO2 to SO3. The platinum group metal compositions soluble or dispersible in the diesel fuel and are added in amounts effective to provide concentrations of the metal in the fuel of less than 1 part per million (ppm).

Abstract: In a rolling mill, data representing the axial distance of the center of each groove of a work roll from a first reference location on the work roll is determined and stored in the memory of a data processing system. The work rolls are then mounted in the roll stand and the grooves of a selected "setup" roll pass are brought into alignment with each other. The roll stand is then placed on the rolling line, the setup pass is aligned with the mill passline in the case of vertical stands, or with the mill center line in the case of horizontal roll stands, and data representing the relative positions of the work rolls to the roll stand and of the roll stand to another reference location is obtained and stored in the memory of the data processing system. Using this data, the system then calculates and automatically effects adjustments to the roll stand and work rolls in order to precisely align other roll passes with the mill passline or center line.

Title: Chemical signal-impermeable mask
Inventor: TIERNEY MICHAEL
IPC: A61B5/145
Filed: 1996-07-16
Granted: 2001-10-09
Abstract: A chemical signal-impermeable mask (1) is positioned in the electrolyte flow such that the mask is between a source of chemical signal and a working electrode (4) which senses the chemical signal transported from the source (e.g., by diffusion). The configuration of the mask is such that the mask prevents substantially all chemical signal transport from the chemical signal source/having a radial vector component relative to a plane of the mask/and the catalytic face of the working electrode, thus allowing primarily only chemical signal transport that is substantially perpendicular to the place of the mask and the catalytic surface (6) of the working electrode. By reducing or eliminating chemical signal radial transport toward the working electrode, the mask thus significantly reduces or eliminates edge effects. By substantially reducing edge effects created by radial transport of chemical signal, it is possible to obtain a more accurate measurement of the amount (e.g., concentration) of chemical signal that is transported from a given area of source material.

Title: Class-of-service automatic routing
Inventor: DEORA SANJEEV K
IPC: H04Q3/545
Filed: 1998-02-27
Granted: 2000-07-11
Abstract: Local/toll dynamic routing integration is achieved within a telecommunications network (14) that includes at least one dynamic routing localswitching system (24-1) for receiving incoming calls and a plurality of toll switching systems (27-1 through 27-7) at least one of which is associated with each local switching system. For each incoming call, the local switching system (24-1) derives a set of Class-Of-Service (COS) parameters indicative of the class-of service associated with the call. In accordance with the COS parameters, the local switching system (24-1) determines whether each incoming call is a featured call, requiring routing to the toll switching system associated therewith, or a non-featured call. Featured calls are routed to the toll switching system associated with the localswitching system for feature processing, whereas non-featured calls are routed by the local switching system itself in accordance with the COS parameters, thus relieving the load on the associated toll switching system. A technique called Class-of-Service Automatic Routing (CSAR) allows the local/toll dynamic routing network integration with class-of-service routing capabilities. CSAR provides a simplified implementation of dynamic routing, which builds on real-time network routing (RTNR) and success-to-the-top (STT) routing. RTNR uses the exchange of real-timestatus information through Common Channel Signaling (CCS) to select the best route on a call-by-call basis. STT, on the other hand, uses a technique to search routes until a successful route to the destination is found, and that successful route is used for all calls until blocked whereupon a new successful path is sought. CSARuses RTNR when both the originating switch and terminating switch have RTNR capability, but uses the STT routing method when either the originating switch or terminating switch does not have RTNR capability. Furthermore, STT routing and RTNR routing can be combined in CSAR depending on the capabilities of the switches encountered in the call path. CSAR provides local/toll network integration, with class-of-service routing capabilities, yielding the benefits of dynamic routing, which include (a) improved service quality, (b) increased service flexibility, (c) additional revenue and revenue retention, and (d) cost reduction.

Abstract: A method for providing an open interface, or access to, information that is stored in a called party switch in relation to an automatic recall telecommunications service. Automatic recall service allows a customer to dial a special feature code and receive an enunciation of the directory number of the last incoming caller. Typically, automatic recall-related information is stored in the called party switch and is not accessible to external network elements that may provide enhanced services with this information. This automatic recall-related information may include information such as the directory number of the last incoming caller, the time stamp of the last incoming call, and/or the privacy indicator of the last incoming call. The method includes placing the automatic recall-related information into at least one field of a telecommunications message, such as an ISUP message. The message is routed from the called party switch to the terminating network element that is to provide an enhanced service. The terminating network element may then retrieve the automatic recall-related information from the fields of the message. The terminating network element may then use the automatic recall-related information to provide enhanced services.

Abstract: A stabilization system protects a structural member from  the  effects  of  seismic  disturbances.  Pendular isolators are positioned between a structure fixed to the ground and the structural member,  which is movable and which  is  sought  to  be  protected,  such  as  a  complete building, a building slab upon which sensitive equipment is used, or a bridge deck. The pendular isolators can be rods extending between the building and the slab floor, wherein ends  of  rods  connected  to  the  slab  floor  include  a spherical friction knuckle joint or bearing, i.e., knuckle element/socket  assembly.  Alternatively,  each  pendular isolator can be a set of supports movable relative to each other and connected by at least one rod having a knuckle joint at each end thereof.   The friction at the knuckle joint is utilized to provide a damping of the seismic disturbance,  thereby  permitting  only  limited  relative movement  between  the fixed  structure  and  the  movable structural member in the event of a seismic disturbance. The lengths of the pendular isolators are adjustable.
