Inventor: HART JAMES E
IPC: B60T15/42
Filed: 1995-03-17
Abstract: An access plate mounted between the pipe bracket portion and either the service portion or the emergency portion of a railway freight brake control valve.  Passageways are provided through the access plate, each passageway terminating in a respective access port along an end of the access plate.  Openings extend through opposed sides of the access plate, intersecting respective access plate passageways.  The openings on each side are sized and positioned to sealingly align with openings of the pipe bracket portion and either the emergency portion or the service portion.  The openings on the pipe bracket portion, emergency portion and service portion connect to passageways communicating to the brake pipe, the brake cylinder retaining valve, the brake cylinder, the emergency reservoir and the auxiliary reservoir.  A housing may be attached to the pipe bracket portion to connect to the access ports, such housing preferably having a valve means for preventing the escape of fluid pressure therefrom.   An adaptor may engage with the housing, opening the valve means and allowing the fluid under pressure to enter the adaptor.  A removable outer cover may be provided over the access housing once the adaptor is removed for providing additional sealing of the fluid under pressure.

Title: Unitary components and molecular belt assembly
Inventor: DARINGER RONALD G
IPC: B65G17/06
Filed: 1995-03-24
Abstract: A weld-free belt is formed by inter-coupled modular assembly of individual unitary components including an elongated link portion and transversely-oriented connector means which provide a self-coupling coaction forming an integral rod extending across the width of an assembled belt.   The inter-locked components are articulated for relative rotational movement across the width of the belt facilitating orderly movement of an assembled belt around curved portions of an endless travel path.  Dimensions of the  components  can  be  selected  to  determine  the lengthwise-collected relative motion between inter-coupled unitary  components  to  achieve  desired  travel  in  a substantially-horizontal curvilinear path about a tower, in stacked conveyor paths, with the internal-circumference lateral side of an assembled belt providing for dynamic frictional drive in the curved-path tower arrangement.          The  unitary  component  configuration  provided  by  the invention enables component manufacture to be carried out by  molding  plastic  materials,  and/or  by  compacting particulate  ceramics  or  powdered  metals  which  are subsequently sinter hardened.

Patent CA-2163476-A1 (CA)
Title: Fuel handling system
Inventor: COTTON KENNETH J
IPC: F02M37/00
Filed: 1995-11-22
Abstract: A fuel handling system for an internal combustion engine having a vapor separator for receiving fuel from a remote tank and a pump for delivering the fuel under high pressure to a fuel injector of the engine while providing vapor separation.          The separator has an inlet for receiving fuel from the tank, an outlet for enabling fuel to be removed and delivered to the engine, at least one return for enabling fuel not used by the engine to be returned to the separator, and a vent for removing fuel vapor from a gas dome above a pool of liquid fuel within the separator.  The inlet has a valve controlled by a float in the reservoir for admitting fuel to maintain the level of liquid fuel  in  the  separator.   To  retard  foaming  and  excessive vaporization of liquid fuel in the separator, the separator has a perforate baffle between any return and the liquid fuel pool.          To prevent any stream of returned fuel, vapor and/or air from impinging against the fuel pool, the baffle preferably has a plurality of through-openings which enable liquid fuel to pass through the baffle to the pool while deflecting any return stream away from the fuel pool.  The baffle preferably extends outwardly to the separator sidewall for preventing any return stream from passing around the baffle and directly impinging against the liquid fuel while at least slightly pressurizing gas below the baffle for controlling vapor venting to the engine.

Title: Process for desulfurizing a h2s -containing gas
Inventor: STETZER KLAUS
IPC: B01D53/86
Filed: 1996-03-01
Abstract: The H2S-containing gas is passed through at least one bed of a catalyst rich in metal oxide and subsequently through a final cleaning bed. On the catalyst rich in metal oxide and in the final cleaning bed elementary sulfur is deposit-ed, which is removed by a regeneration treatment carried out periodically. The final cleaning bed constitutes a fil-ter bed for the adsorption of elementary sulfur and con-sists of a granular adsorbent, which is different from the catalyst rich in metal oxide. A gas coming from the cata-lyst rich in metal oxide is supplied to the filter bed at temperatures in the range from 20 to 180C, which gas con-tains at least 250 mg elementary sulfur per Nm3 gas. From the filter bed a desulfurized gas is withdrawn, whose con-tent of elementary sulfur is not more than 30 % of the con-tent of elementary sulfur when entering the filter bed.

Title: User-transparent security method and apparatus for authenticating user terminal access to a network
Inventor: ENSOR MYRA L
IPC: H04Q3/00
Filed: 1996-03-25
Abstract: The present invention provides a password authentication security system for a telecommunications network (100) having a plurality of user terminals or subscriber stations (110) communicably coupled to the network (100). The system comprises anetwork control or service center (108) coupled to the subscriber stations (110), to service provider stations (102) and to network databases (104, 106) via the network (100). Upon establishment of a communication with a subscriber station (110), a network coupling identifier comprising in one embodiment the telephone number of the line to which the subscriber station (110) is connected is detected at a telephone switching office (120) and transmitted to the control center (108). If this is the first time communications have been established between the subscriber station (110) and the network (100), the received telephone number is encrypted to produce a secret password that is then automatically transmitted to the subscriber station (110) for storage in memory (126). Upon subsequent communications, the telephone number is again received by the control center (108) where it is encrypted to produce a second password. The first password is then automatically retrieved from memory (126) of the subscriber station (110) independent of user interaction. The two passwords are compared, and the network control center (108) causes the incoming call from the subscriber station (110) to be connected to a network service provider station (102), a network database (104, 106), a network output device or the like if the passwords are at least similar. If the two passwords are not at least similar, the control center (108) causes the incoming call of the subscriber station (110) to be disconnected, thereby terminating the subscriber station's access to the network (100).
