A vertical conveyor device for accommodating motor vehicles of varying heights. Short and tall containers for motor vehicles alternate around a vertical carousel. When a container is placed in an accessible position, movable walkways and ramps change positions allowing patrons and vehicles easy access to the containers. The positions of the walkway and ramp vary depending on the heights of the containers and vehicles.

An elevated pressure and temperature fluid processing system providing a pressurized fluid delivery system including a process fluid supply system and pump for supplying a process fluid at a process pressure, and a process fluid heater for heating the process fluid; a process chamber with a process chamber heater; and a process discharge collection system. The system also provides a process chamber inflow valve for connecting the pressurized fluid delivery system to the process chamber for fluid flow, and a process chamber outflow valve for connecting the process chamber to the collection system for fluid flow. A process chamber bypass valve connects the pressurized fluid delivery system to the process discharge collection system so as to bypass the process chamber. A computer control system controls the pump, the process fluid heater, the chamber heater, and the valves.

An exercise apparatus includes a handle bar and a resistance assembly, coupled to the handle bar. The resistance assembly includes a housing having first and second opposed parts, and permitting movement of the handle bar about a rotational axis upon applying force to the handle bar. A resistance mechanism resists movement of the handle bar about the rotational axis. A screw, mounted lengthwise along the rotational axis, and engaging a threaded receptacle, adjustably compresses the spacing between the housing parts and modifies resistance to movement of the handle bar. One of the screw and the receptacle is coupled to an adjustment knob setting a user-defined resistance. A clamp, coupled to the housing, removably attaches the exterior of the first housing part to a member. A user grasps the handle bar and moves it by applying force corresponding to the resistance setting. The clamp can be utilized without operating the knob.

Embodiments of the present invention are directed to a video probe for viewing an object and for viewing a device that acts on the object. In one embodiment, the video probe includes a first viewing channel having a viewing direction along a first optical axis to provide an image of the object, a second viewing channel having a viewing direction along a second optical axis that is substantially parallel to the first optical axis, and wherein the viewing direction of the second channel is substantially the same as the viewing direction of the first viewing channel, and an imaging system to receive the image of the object and the image of the device from the first and second viewing channels. Embodiments of the present invention are also directed to a method and apparatus for printing a pattern on a substrate using a printing screen having the pattern defined thereon. A video probe is used to view the printing screen and the substrate prior to printing to provide image signals which are used to properly align the printing screen with the substrate prior to printing.

A supercritical fluid cleaning system uses process fluid for operating rotary motors in the chamber with fluid bearings and fluid load levitation for rotating workpieces and impellers. Rotating speed and direction sensors and a home position locator facilitate motor control. Impellers add further agitation of the fluid in the chamber, faster processing, and greater uniformity of supercritical fluid components and increase mass transfer of fluid to the processed surface. Centrifugal operated clips and cassettes hold wafers and impellers. Non-contact, fluid operated rotating mechanisms reduce contamination. Physical, rotational, and shear affects are enhanced through centrifugal forces which can induce the separation of films localized deposits or molecular products of the reaction from the surface. There is a concomitant agitation of fluid, and continuous angular acceleration imparted to the processed surface features.

Pipe coupling apparatus including a tubular female coupling structure and a tubular male coupling structure sized to fit within and mate with the female coupling structure, one coupling structure including a housing and a locking ring that is radially deformable within an annular supporting groove of the housing, the other coupling structure including a tapered surface for biasing the ring to vary its radius as the coupling structures are brought together and an annular locking groove for receiving the ring when it is aligned with the locking groove as the coupling structures are moved further together and the ring springs back toward its undeformed shape, one coupling structure carrying an annular seal to provide a fluid-tight seal between said coupling structures.
