Title: In-cylinder combustion recipe for meeting tier 2 locomotive emissions regulations
Inventor: GLENN W DOUGLAS
IPC: F02D29/02
Filed: 2004-05-06
Abstract: A diesel engine (E) has a combustion chamber (C), a piston (T) movable in the chamber, air intake and exhaust valves (IV, EV), and a nozzle (N) injecting fuel into the combustion chamber. By controlling hydraulic flow characteristics of an air-fuel mixture particulate matter (PM) produced by combustion of the air-fuel mixture in the chamber is reduced to a level which meets the Tier 2 requirements established by the Environmental Protection Agency (EPA) for the engine. This is further accomplished by increasing the injection pressure of the fuel injected into the chamber, changing the size and/or shape of the injector nozzle to increase a ratio of the air to fuel while fuel is injected into the chamber through the nozzle, increasing the compression ratio within the combustion chamber, lowering the manifold air temperature (MAT), and retarding the start of injection (SOI) within the chamber. Besides reducing particulate matter to within the Tier 2 limits, the NOx produced by the engine is also maintained within the Tier 2 requirements, and the engine's fuel consumption is reduced.

Inventor: OFCA WILLIAM W
IPC: F42C19/12
Filed: 2004-05-20
Abstract: A device for initiating an electric detonator utilizing an open circuit to decrease occurrences of accidental detonation. The device may include an initiator housing (12), at least two conductor pins (14) disposed through the initiator housing and spaced within the housing such that they are electrically isolated from one another, and a primer spot material (16) disposed between the conductor pins. The primer spot material may be comprised of a mixture of reactive material and metal component. The primer spot material has electrical properties which provide resistance to conducting an electrical current to maintain an open circuit condition prior to occurrence of a breakdown voltage which is dependent upon the amount of metal component in the primer spot material. Subsequently, the primer spot material has electrical properties which provide a conductive medium on the occurrence of an electrical arc between the conductive pins that arises at voltages in excess of the breakdown voltage. Finally, the electrical properties are such that the electrical arc provides energy to form a plasma from the primer spot material, leading to initiation of the detonator.

Patent CA-2533656-A1 (CA)
Inventor: ODDSEN DENNIS A
IPC: H01H13/00
Filed: 2004-07-23
Abstract: There is disclosed a paddle switch operated by pushing on the lower portion of a rocker paddle to turn the switch ~on~ or ~off~. The lower edge of the paddle pivots in and out about its upper edge. The switch includes articulated driver means coupled to be driven by the rocker paddle when it is depressed and to urge the rocker paddle back to its out position. When the rocker paddle is pushed in, it urges the articulated driver means to rotate a cam means in a first, clock wise direction, or a second, counter clockwise direction.  Alternate rotation of the cam drives a slider member having a cam follower back and forth along a linear axis. A shaped leaf spring cooperates with the cam follower to assist in the movement of the slider and to determine its rest positions. An indicator such as an LED is used to indicate the state of conduction of the switch. When the rocker paddle is released, it is biased by the articulated drive means to pivot back to its initial position. The rocker paddle of the switch is not located within a frame and has surface along its vertical axis of positive first differential and zero second differential, comprised of a combination of splines which extend between points of varying distance from a datum plane. This surface has zero second differential when the rate of height increase of individual splines is constant.

Abstract: The present invention discloses a system (100) and method for adaptive adjustment of bit budget based on the content of the input image sequence. In one embodiment, two encoders (110, 120) are employed in a dual pass encoding system. A first encoder (110) receives the input image sequence and encodes each frame of the image sequence using a standard or any predefined encoding algorithms. Specifically, by encoding the image sequence using the first encoder (110), the first encoder (110) is able to assess the complexity of each picture in the image sequence, e.g., by measuring the number of bits needed to encode each picture. This complexity information serves as look-ahead information for a second encoder (120).
