    摘要: A lockable package includes an outer sleeve defined by connected first and second panels, the sleeve having at least one open end. An inner container is slidable within the sleeve, and having a first portion joined to a second portion, wherein at least one of a height and a width of the first portion is less than a corresponding height and width of the second portion. A difference between one of the height and the width of the first portion and the corresponding height and width of the second portion defines a ridge. A locking assembly is provided at the at least one open end of the sleeve and is configured to releasably engage the ridge, wherein the inner container is removable through the open end of the sleeve by disengaging the locking assembly from the ridge.

    摘要: A nitridation treated stainless steel article (such as a bipolar plate for a proton exchange membrane fuel cell) having lower interfacial contact electrical resistance and better corrosion resistance than an untreated stainless steel article is disclosed. The treated stainless steel article has a surface layer including nitrogen-modified chromium-base oxide and precipitates of chromium nitride formed during nitridation wherein oxygen is present in the surface layer at a greater concentration than nitrogen. The surface layer may further include precipitates of titanium nitride and/or aluminum oxide. The surface layer in the treated article is chemically heterogeneous surface rather than a uniform or semi-uniform surface layer exclusively rich in chromium, titanium or aluminum. The precipitates of titanium nitride and/or aluminum oxide are formed by the nitriding treatment wherein titanium and/or aluminum in the stainless steel are segregated to the surface layer in forms that exhibit a low contact resistance and good corrosion resistance.

    摘要: A method of developing a set of input forces used to analyze tire wear includes the steps of characterizing a wear course by driving a vehicle over the wear course and measuring data related to a plurality of forces experienced by the vehicle. A vehicle characterization model for a target vehicle having at least one tire is developed. The vehicle characterization model is used to calculate force data that represents the forces that would be experienced by at least one tire of the characterized vehicle if the characterized vehicle were driven over the characterized wear test course in the first vehicle configuration. The force data is then used to analyze tire wear using a computer prediction technique or by running an indoor wear test on the tire.

    摘要: Mining apparatus is disclosed in which a cutting wheel supporting a plurality of roller-cutters rotates about a horizontal axis and is supported on a slewing boom for cutting a tunnel with a flat floor and roof and elliptical walls as it slews across a mining face. The slewing boom is supported on a main beam assembly, the front end of which rests on powered crawler tracks and the rear end of which passes through a gripper assembly which may be clamped between the floor and roof of the tunnel, and against which the main beam assembly may be urged forward for engaging the roller-cutters with the mining face. A preload crawler is urged against the roof of the tunnel above the powered crawler tracks to locate the main beam assembly rigidly relative to the tunnel such that the roller-cutters may cut the rock in the mining face with minimal loss of cutting force due to vibration. Apparatus for automatically controlling one or more of cutter penetration depth, cutter penetration rate and cutter slew rate, which includes a sensor for sensing a given mining machine parameter, a processor for processing the given mining machine parameter to provide one or more of an optimum cutter penetration depth, cutter penetration rate or cutter slew rate value, and a controller for controlling one or more of cutter penetration depth, cutter penetration rate and cutter slew rate based on the derived optimum value.
