Abstract: A linear ball screw actuator assembly and a method of constructing it. The actuator assembly has a housing for a ball screw and ball nut which together define a raceway between them for a recirculating ball bearing train of balls, one of the screw and nut being reciprocable along a z axis responsive to rotation of the other and being adapted to be coupled to a member to be actuated. The housing has gearing for transmitting rotation to the other of the ball and screw nut in a direction lateral to the z axis. A base for the housing is spaced from the housing and has a base journal journaling the first pin extending along a first pin axis laterally perpendicular to the z axis. The housing has a housing journal journaling a second pin extending crosswisely perpendicular to the first pin. The second pin axis intersects the z axis and x axis. The pins are coupled in a manner to permit relative rotation of the base and housing about either pin axis, or both, to obviate misalignment problems.
Abstract: An air abatement system that includes a pre-treatment system and an air treatment system for abatement of contaminated air that includes pollutants such as V.O.C.s, NOx, and/or CO. The air stream is treated using activated air, activated water, and ultraviolet light under conditions that produce hyroxyls, peroxides, and other oxidants without the formation of ozone. These oxidants are also utilized in the activated air, with the activated water being formed as an aqueous solution of the activated air. The pre-treatment system includes a quenching zone where activated water is misted into the air stream, followed by alternating reaction zones and depletion zones where activated air is added and then turbulently mixed with the air stream. The air treatment system includes a primary treatment tunnel, carbon bed system, activated air generator, and a sparger tank farm. Activated air produced by the generator as added into water while being exposed to ultraviolet light in the sparger tank farm.

Abstract: A crash sensor for automobiles of the type including a ball moving against viscous damping in a closed tube has a much smaller hall than known designs and a power transistor to switch power in the firing circuit. A resistance sensing circuit enables the crash sensor to monitor the firing circuit and indicate a change in the resistance of the fining circuit. In two embodiments simple message patterns allow communication of diagnostic information through existing wiring. A latching circuit maintains the switch in its closed state after initial closing. The small size of the ball enables use of a plastic or aluminum tube. The tube may have fluted walls that form air ducts that viscously conduct much of the air displaced when the ball moves. Routing most of the air through the ducts eliminates the uncertainty in the viscous resistance resulting when all of the air flows between the ball and the inner diameter of the tube. The movable element may be a sensing mass having a nonspherical shape.

Abstract: A combination vent valve/purge valve apparatus (10) for an automotive fuel vapor recovery system canister (14) comprises a purge valve (26) and a vent valve (16) in a single housing. When open, the vent valve (16) allows outside air to enter the canister (14). The purge valve (26), when open, allows fuel vapor to flow from the canister (14) into a vacuum source (12). A gas channel (28, 130, 168) extends between a vent chamber (18) within the vent valve (16) and a purge chamber (28) within the purge valve (26). When the purge valve (26) is open and a purge plunger (86) within the purge chamber (28) is positioned away from the gas channel (28, 130, 168), the manifold vacuum draws air from one side of a diaphragm (126) within the vent chamber (18) drawing the diaphragm (126) and a vent plunger (152) downward against a spring to close the vent valve (16). When the purge plunger (86) is positioned to block the gas channel (28, 130, 168), the spring forces the vent plunger (152) upward to open the vent valve (16).
