Title: Railway hopper car discharge gate assembly
Inventor: DOHR JEREMY J
IPC: B61D7/26
Filed: 1997-08-26
Abstract: A discharge gate assembly for a railway hopper car that satisfies the new AAR requirements and specifications and includes a frame defining a generally rectangular discharge opening with a gate slidably mounted on the frame for endwise horizontal movement between opened and closed positions. An operating shaft assembly is supported on opposite frame extensions for rotational movement about a fixed axis. The operating shaft assembly is operably coupled to the gate. A lock assembly is operably coupled to the operating shaft assembly and includes a vertically displacable stop member mounted for vertical and rotational movement about a fixed axis extending above the path of movement of the gate and in fore-and-aft relationship relative to an edge of the gate.  When the gate is in its closed position, the stop member extends downwardly and into engagement with the gate edge to positively prevent the gate from substantial movement toward an open position. A drive mechanism is disposed adjacent the frame extensions for positively displacing the stop member from the path of travel of the gate in timed relation relative to movement of the gate toward an open position.

Abstract: A method to verify in a host system that the expected PSD is coupled to the host. The host system generates a message, such as a random number and sends to the PSD. In one embodiment, the random number is signed in the PSD. The signed number is transmitted to the host where the signature is verified. In an alternate embodiment, the PSD encrypts the number and transmits it to the host system. The host system decrypts the encrypted number and ensures it corresponds with the number originally generated and transmitted to the PSD. Methods for verifying in a PSD that the expected host is coupled to the PSD mirrors the two embodiments for verifying the expected PSD. The generated message may include data indicating status of the PSD based, for example a checksum of PSD transaction records stored in the host system.

Patent CA-2225254-A1 (CA)
Inventor: JOUIN JEAN-MARIE
IPC: D04H1/46
Filed: 1996-06-18
Abstract: Preforms for producing annular parts of composite material are produced by winding a strip (1) of fibrous material around an elliptical mandrel (10) to produce an elliptical sleeve which can be cut obliquely, cutting taking place either before or after one or more densification steps. The cutting plane is inclined relative to the right cross section of the elliptical sleeve, and the inner and outer portions of the cut rings are machined to obtain circular elements. Such elements can produce annular parts of composite material having a reduced tendency to delamination under circumferential stress. The superposed layers are needling together during winding. A uniform needling density per unit area can be obtained by controlled displacement of the needle board (5) and of the elliptical mandrel (10) relative to each other as the mandrel turns, to compensate for the eccentricity of the cross section of the mandrel. These methods are particularly suitable for producing brake disk preforms.
Patent CA-2225504-A1 (CA)
Inventor: PAFFENHOLZ JOSEF
IPC: G01V1/38
Filed: 1997-12-22
Abstract: The two-way water-layer travel time, ~, is derived from dual-mode seismic sensor data by cross-correlating the Fourier transforms of the sum and difference of the velocity and pressure signatures.  The Z-transform of ~ evaluates one of the two Backus variables, Zw. The second variable is Rb, the water bottom reflectivity coefficient. The frequency-domain transforms of the above summed and differenced signatures are each multiplied by the Backus operator (1+RbZw)2  after initializing Rb and the products are iteratively cross-correlated  until the correlation function converges to a minimum.  Rb is perturbed after each iteration.  The value of Rb upon convergence is the local water bottom reflectivity coefficient.

Patent CA-2229880-A1 (CA)
Inventor: FUKUNO HIROKI
IPC: F01D11/02
Filed: 1998-02-19
Abstract: The invention relates to a gas turbine seal structure between end portions of a moving blade platform and a stationary blade inside shroud,  in which a sealing performance is improved by increasing a resistance  of a flow.  A seal plate (21, 31) is mounted to an end portion of a platform (2, 2') of a moving blade (1) and a seal portion is constituted by a seal fin (22, 32) and a honeycomb seal (16,  17) disposed to a lower surface of an end portion (12a,  12b) of an inside shroud (12) of a stationary blade (11).  A sealing air from the stationary blade (11) produces a high temperature in a cavity (14) and is flown into a space (18, 19),  and also an air leaked from a cooling air of the moving blade (11)  is going to escape to a high temperature combustion gas passage from the space (18,  19) through a seal portion, however, since three seal fins (22, 32) of the seal plate (21, 31) are inclined in such a manner as to oppose to the air flow,  the air resistance is increased and the flowing-out of the air is prevented.  Accordingly,  a sealing performance is improved in comparison with the conventional structure having no seal fin (22, 32).

IPC: C08F2/00
Filed: 1998-06-25
Abstract: Disclosed is a process for propylene polymerization comprising the steps of feeding propylene containing not less than 0.1 % by weight and not more than 20 % by weight of propane to a polymerization reactor, distilling at least a part of unreacted propylene discharged from the reactor to remove propane contained in the unreacted propylene, and circulating the purified propylene into the polymerization reactor, whereby propane is drawn out from the polymerization reaction system.  The propane concentration in the unreacted propylene discharged from the polymerization reactor is in the range of usually 90 to 98 % by weight, and the purified propylene concentration to be circulated into the reactor after the distillation can be set in the range of 60 to 98 % by weight.  At least a part of the purified propylene obtained after the distillation is preferably circulated into the reactor as a liquid.          According to the process for propylene polymerization, propane is efficiently drawn out from the polymerization reaction system, whereby propylene can be efficiently polymerized, and besides the size of an apparatus for distillation of propylene can be made small.

Title: Signal processing apparati and methods for attenuating shifts in zero intercept attributable to a changing boundary condition in a coriolis mass flow meter
Inventor: SCHOTT MICHAEL N
IPC: G01F1/84
Filed: 1997-03-13
Abstract: In the field of Coriolis mass flow meters, determination of the true zero of the meter has always been problematic due to zero drift effects with changing boundary conditions and fluid parameters. Disclosed are apparati and methods for determining the true mass flow related component of the signal of the meter separately from errors caused by changing boundary conditions and fluid parameters. Accordingly, an apparatus for measuring a mass flow rate of a fluid flowing relative to a flow conduit includes: (1) a force driver for vibrating the flow conduit; (2) a sensor for measuring a resulting motion of the flow conduit and producing a sensed motion signal indicative thereof, the resulting motion containing a Coriolis mode component and a boundary condition mode component; (3) signal processing circuitry, coupled to the sensor to receive the sensed motion signal therefrom, for determining a magnitude of the Coriolis mode component of the resulting motion; and (4) output circuitry for producing an output signal proportional to the mass flow rate, the output signal substantially free of influence from the boundary condition mode component of the sensed motion signal.
