A fiber guide for spooling glass fiber from an automatic coil winding machine onto a spool. The guide has a body or pay guide assembly with a receiving aperture. Two similar sections are held together with a slight gap between them. Left and right parallel strands of music wire are tightly stretched through the gap across the receiving aperture of the arc and are anchored at each end. A spool with flanged edges receives the left and right parallel strands or guides and is maintained very close to the last layer or surface of fiber laid down. A guide pulley is carried by the guide for guiding glass fiber between the left and right parallel strands and onto the spool. The parallel strands are tensioned by anchoring each wire in a respective standoff. In one embodiment, each end of a music wire wraps around a standoff. The wires extend through the cross drilled holes permitting adjustment by turning the standoff. In an alternative embodiment, a tensioner is formed by a pivotal plate, relative to the guide. The pivotal plate tightens the left and right parallel strands by spring force generated by a spring connected between the pivot plate and the guide. In yet another embodiment, the left and right parallel strands are spaced apart by washers having a predetermined thickness and clamped.

An input optical fiber (22), an output optical fiber (24, 26) and a waveguide (14) in an integrated optic chip (IOC) (12) intermediate the fibers are coupled together using service and alignment robots (42; 48, 50, 52). The service robot (42) establishes the three dimensional position of the waveguide. The alignment robots (48, 50, 52) three dimensionally and angularly align the input and output fibers respectively to the input and output legs (16; 18, 20) of the waveguide. An adhesive applying tool (46) coupled with the service robot adheres the input and output fibers respectively to their waveguide input and output legs. Included are specifics for an optical fiber clamp (110) capable of maintaining the orientation of a fiber while it is moved to another location, a vacuum holder (210) for holding and rotating an optical fiber for polarization purposes, goniometer mapping and positioning of an optical fiber with respect to the pivotal axis of the goniometer (324), initial light launching of an optical fiber to a waveguide using the fiber (422) in its cladding mode, planar and angular position alignment of optical fibers to optical waveguides, an alignment procedure for establishing a gap between waveguides, and attaching optical waveguides together.

Fluid cleaning apparatus for precision parts, comprising in combination, a chamber, having a fluid inlet and a fluid outlet, for holding parts to be cleaned and a fluid tight recirculating flow system including the chamber. The fluid tight system directs supercritical carbon dioxide fluid flow across the parts being cleaned. A fluid recirculating cylinder has a first fluid port and a second fluid port connected in the flow system. A fluid piston is in the cylinder between said ports. A pneumatic cylinder has a further piston between a first pneumatic port and a second pneumatic port. A driving member is connected between the pistons for reciprocal movement caused by air from a source alternately introduced to the pneumatic ports to cause the fluid piston to pump fluid through the chamber and back to the recirculating cylinder. A shuttle valve is connected between the air source and the pneumatic ports. Two actuators are responsive to different positions of the driving member for switching the shuttle valve alternately to direct air from the supply to the pneumatic ports and exhaust used air. A plurality of one way valves are in the system to insure that the fluid pumped by the piston exhibits unidirectional flow through the chamber. A filter is connected in the fluid flow system upstream of the chamber.

An improved golf practice tee apparatus for practicing golf swings is disclosed which provides a golf tee platform that may be selectively adjusted both in angle and in orientation to thereby allow the user of the device to simulate a wide variety of uneven lies. The golf practice tee apparatus has a platform mounted on a platform support frame, which platform support frame is centrally supported above and away from a base frame by a universal member which allows the platform support frame to move with two degrees of freedom of movement with respect to the base frame. Movement of the platform frame with respect to the base frame is controlled by four hydraulic cylinders, movement of which may be selectively, alternatively permitted to allow the angle and the orientation of the platform support frame to be adjusted, or inhibited to freeze the position of the platform support frame with respect to the base frame.
