Title: Integrated train electrical and pneumatic brakes
Inventor: ALLEN JOHN J
IPC: B60T15/14
Filed: 2000-09-13
Granted: 2008-11-18
Abstract: An integration train brake system including a single brake controller providing locomotive and train brake commands. A first control transmits a car brake signal on an electrical network for train brake commands to EP cars. A second control transmits a locomotive brake signal on the locomotive brake pipe for train and locomotive brake commands. The brake system may have a pneumatic mode and an electrical mode. The first control transmits car brake signals on the network in the electrical mode and the second control transmits car brake signals on the train brake pipe for the pneumatic mode. The second control transmits locomotive brake signals on the locomotive brake pipe in either mode. If the train is all electropneumatic, cars and locomotive braking signals are provided on the network. Distributive power may also be transmitted over the network in the electrical mode.

Abstract: A telecommunications network has a target exchange (RNC 222 2) which determines a congestion condition in a region supervised by the target exchange, and which sends a congestion message to a source exchange (RNC 222 1). The source exchange controls at least some connections which utilize radio resources in the region supervised by the target exchange. The congestion message causes the source exchange to adjust at least one connection which it controls in the region supervised by the target exchange. In a first mode of the invention, the target exchange determines a selected connection to be adjusted in view of the congestion condition. In this first mode, the congestion message identifies the selected connection to be adjusted and further includes an adjustment value (e.g., power reduction value) for the selected connection to be adjusted. In a second mode of the invention, the congestion message includes an identification of a congested area (e.g., a cell) within the region supervised by the target exchange, as well as a severity value indicating a severity of the congestion in the congested area. The severity value can be indicative of a needed decrease in congestion in the congested area.

Abstract: A diffuser master is provided which is manufactured mechanically instead of holographically. The master can be made from a suitable substrate including relatively hard materials such as plastic, glass or metal. A substrate (30, 50, 70) having a first side (32, 52, 72) is worked to form a diffuser surfac e relief structure (33, 53, 73) thereon. The substrate can be buffed using a buffing agent (34) of a selected grit in order to form surface scratches in the first side of the substrate. The substrate can also be blasted with shot particles (80) in order to form indentations and depressions in the first side. The substrate can alternatively be acid or alkali etched in order to form surface irregularities in the first side. The scratches, depressions or irregularities can be formed in order to create a desired surface relief and hence desired diffuser output characteristics.

Title: Membrane-assisted fluid separation apparatus and method
Inventor: KAZI ABDUL M
IPC: B01D63/04
Filed: 2001-06-22
Granted: 2009-09-15
Abstract: This present invention relates to a fluid separation module adapted to separate a given fluid mixture into permeate and retentate portions. The fluid separation module holds one or more bundles of hollow fiber membranes. The membranes may be composed of different kinds of membranes depending on the application being used to separate the fluid mixture. The fluid separation module may be used to separate fluid mixtures by a number of different processes, including but not limited to, pervaporation, vapour permeation, membrane distillation (both vacuum membrane distillation and direct contact membrane distillation), ultra filtration, microfiltration, nanofiltration, reverse osmosis, membrane stripping and gas separation. The present invention also provides an internal heat recovery process applied in association with those fluid separation applications where separation takes place by evaporation through the membrane of a large portion of the feed into permeate. Desalination and contaminated water purification by means of vacuum membrane distillation are just two examples where the internal heat recovery process may be applied. In these two examples, large portions of the feed are separated by membranes into a high purity water permeate stream by evaporation through the membranes and into a retentate stream containing a higher concentration of dissolved components than present in the feed. In this process the permeate vapour that is extracted from the fluid separation module is compressed by an external compressor to increase the temperature of the vapour higher than the temperature of the feed entering the separation module.  Heat from the permeate vapour at the elevated temperature is transferred back to the incoming feed fluid mixture entering the fluid separation module in a condenser/heat exchange.

Abstract: A mobile service rig for servicing an oil well includes a variable speed engine and a multi-speed transmission that selectively powers a drive wheel for transport, a hoist for lifting and lowering well-related components, and a hydraulic circuit for a tong used in tightening and loosening sucker rods or tubing. A speed adjuster operatively coupled to the engine limits the speed of the engine when the tong is operating, while a flow restriction limits the rate of hydraulic fluid flowing through the tong. Such an arrangement reduces power consumption, reduces heat, and avoids over tightening a sucker rod connection.

Title: Method and apparatus for detecting seal failure
Inventor: UPTON MARK
IPC: F16J15/56
Filed: 2003-03-26
Granted: 2011-01-18
Abstract: Pumps and valves with movable parts, such as a plunger, typically have seals around the part. The seals may isolate one chamber from another to prevent leakage across the seals. The pressure in one chamber may be different from the pressure in another adjacent chamber, thereby creating a pressure differential across the seal. When the seal is working properly, the pressures in the adjacent chambers remain constant approximately. However, when a seal leaks, pressure will leak across the seal. As such, the chamber with the lower pressure will show an increase in pressure due to seal leakage. Thus, monitoring pressure changes in the chamber with low pressure, or pressure differentials between chambers, serves as an indicator for leakage across the seal and impending seal failure.
