摘要:
The present invention is generally directed toward a method of measuring surfactant penetration into a foam layer of a filter for an air filter assembly. The method comprises the addition of a dye to a surfactant, adding the dye laden surfactant to the foam layer, illuminating the foam layer after the dye laden surfactant has been added, observing the amount of illumination, and determining the amount of surfactant penetration by the amount of illumination of the foam layer.
摘要:
A system that enables enhanced air flow to the air intake of an internal combustion engine having a turbocharger is disclosed. The air induction system includes a plenum or expansion chamber located within the area directly in front of the inlet of the turbocharger. Alternatively, the air induction system may include a means for reducing the velocity of the air flow within the clean air duct in an area directly in front of the inlet of the turbocharger.
摘要:
A truss hinge that allows hinging between truss parts, and also allows configuration into a different size, and spreads the angle of the truss open ends. One embodiment uses a first plate, having a connection part to a first truss, where the connection part is adapted for connection to a first truss. A second plate is movable relative to the first plate. The second plate also has a second connection part adapted for connection to a second truss. An angle setting part forms a connection between the first plate and the second plate, that holds the first plate relative to the second plate at any of a number of different relative locations between the first plate and the second plate. The plates include angle markings to set the connections.

A dual sided extrusion, where one side has a different shape than the other side, and the extrusion is intended to be used in different orientations depending on the application.
摘要:
A movable and steerable device that has a platform with four wheel assemblies, any of which are both drivable and steerable. Different driving and steering options can make the device move in different directions and orientations. The driving can be done by a drive motor, forming a drive loop of material, such as chain, and a steering motor, also forming a steering loop. The different loops are attached to different sprockets on the device, which have different sizes, and therefore the different loops do not interfere with one another.

a device which can slide up and down on a chain or cable, can be loosened to attach to the chain or cable, but does not have any parts that come free when the part is loosened.
摘要:
A winch which can operate with an external brake, or the external brake can be removed to operate with an internal brake. The winch has a cable drum that rotates to get cable on and off the drum. Two eccentric cams are rotated to always keep a soft plastic part pressed against the drum.
摘要:
A winch driven by a rotatable cassette. The cassette can be rotated into multiple different positions. Each of the addition positions produces a different speed up the output for a cable.
