Abstract: A method of polishing a roof-shaped, or bevelled, tip having a predetermined angle on the end of an optical fiber is disclosed. The method comprises placing an optical fiber in contact with an abrasive tape at an angle corresponding to the desired predetermined angle. The fiber is moved towards the tape beyond the point of contact so as to cause a bend in the fiber. Upon moving the abrasive tape, the compliance of the fiber, by virtue of the bend, provides a pressure of the fiber against the tape to enable polishing to occur. As polishing continues the pressure decreases until enough material is removed so as to eliminate the bend and impart the predetermined angle to the fiber tip. The fiber may be rotated to polish the other side in a similar manner, if so desired.

Abstract: A system for protecting a building against the forces generated by an earthquake. The horizontal movement of the building superstructure relative to the foundation is adjustable to adapt its damping system to prevailing wind conditions. The superstructure moves horizontally along a system of movable plates provided at the interface between the superstructure and the foundation. Wind velocity reading devices placed on the exterior of the building provide signals to a transducer which adjusts a controller to vary a threshold force applied to the superstructure to determine the force required to initiate movement of the superstructure relative to the foundation. A sandwiched system of three levels of low friction plates beneath each column, interconnected by three levels of diaphragm linkages, restricts the movement of the columns and walls solely to a combination of orthogonal, rectilinear motion.

Abstract: Conventional apparatus for pressing the track links onto pin and bushings of the track chain during assembly thereof experience difficulty in aligning the links with the pin and bushings because the presses become somewhat loose and out of alignment. The subject apparatus overcomes this problem by providing a self aligning feature in the link locating and driving means. The link locating and driving member is mounted on the pressure plate that is attached to the press rams. A support plate is guided from the pressure plate by guides and resilient members that allow the support plate to shift with respect to the pressure plate with the aid of tapered noses on plungers supported by pressure barrels as the rams move forwardly to press the links onto the pin and bushings held in a fixture. In this manner any misalignment is accounted for by the self-aligning feature of the locating and driving members.

An air-bleed passageway opens on a downstream side of air holes for intaking secondary combustion air to be mixed with secondary fuel and communicates with the outside of the combustor. The air-bleed passageway is provided with a regulating valve and the secondary combustion air is bled at the minimum point of the load where the secondary fuel is supplied so that the fuel to air ratio of secondary premixed mixture may not be excessively lean, thereby reducing the production of non-burned components.

Abstract: A recondenser cycles a working volume of cryogen gas through a remote cold box and a coaxial recondensing, heat exchanger transfer line which is inserted into a cryostat. The working volume of gas is compressed to a high pressure and cooled through cooling means which include a mechanical refrigerator of the regenerator-displacer type.

The liquid-gas mixture is passed in heat exchange relation with the boil-off from an inner tube to an outer tube of a coaxial recondensing heat exchanger.
