Title: An apparatus and method for forming slits
Inventor: AIHARA KINTARO
IPC: B26D3/08
Filed: 1991-05-01
Granted: 1995-09-12
Abstract: A slit forming apparatus consists essentially of a rotary blade assembly, a rotary backing roller, and pressing projections.  The rotary blade assembly contacts with or abuts against a strip-shaped travelling over the rotary backing roller and then penetrates said material to form slits in it.  The backing roller has banks for holding the strip-shaped material pressed by the rotary blade assembly, and also has grooves for receiving the blades of the rotary blade assembly when they penetrate the strip-shaped material.  The pressing projections provided at opposite side ends of the assembly prevent the undersired movement of said material in the lateral or longitudinal direction.  With this apparatus, substantially defect-free satisfactory slits are formed in the strip-shaped material.

Title: Interferometer utilizing superfluorescent optical source
Inventor: FLING JOHN J
IPC: H01S3/07
Filed: 1990-08-30
Granted: 2001-11-20
Abstract: An improved broadband light source for a Sagnac interferometer includes a waveguide (110), such as a fluorescent optical fiber, that is pumped by a pump source (120) with a sufficient intensity to generate temporally incoherent light. The fluorescent optical fiber (110) has first and second ends, one end being an input end of the fiber (110). The broadband light is provided at an output of the fluorescent optical fiber (110) and is input to the interferometer. In order to prevent laser oscillations between the light source and the interferometer, one end of the fluorescent optical fiber (110) is formed so as to prevent reflections. The light output from the fluorescent fiber (110) to the interferometer comprises only that light that initially propagates toward the output of the optical fiber (110). In one embodiment of the light source the pump light from the pump source (120) is coupled into the fluorescent optical fiber (110) in a direction so that it travels away from the output of the fluorescent optical fiber (110) towards that first end. In an alternative embodiment, the fluorescent optical fiber (110) is a doubly clad optical fiber having a first accept-ance region and a second acceptance region at the first end. The pump light is introduced into an aperture window between the two acceptance regions so that the pump light can be introduced into the first end at an angle without requiring a reflective sur-face at the first end.

In one embodiment, the shifter is a cylindrical rod having arms engaging the shift collar of an in-line transmission.  one end of the shifter extends out the front of the transaxle housing and has a square head with a bore for attaching to a lever and linkage.  By moving the lever and thereby pivoting the shifter, the shift collar is axially moved to selectively engage gears gear ratios of the transmission, with the shifter being releasably secured in selected positions by a detent biasing mechanism.  The shifter is positioned below the central plane of the transaxle in the lower housing by a cover plate.  The lever attached to the shifter moves on a vertical arc to pivot the shifter.  In a second embodiment, the shifter is a flat piece which is bent to form an arm and a lever portion.  The arm portion extends out an opening in the lower housing and is bent to form the lever portion which may be attached to and moved by linkage to an operator lever.  A bushing pivotally supports the shifter in the opening and includes a detent biasing  mechanism for releasably securing the shifter at positions which correspond to the gear ratios.  A wall of the housing is positioned in front of the recesses to retain the bushing within the housing.

Abstract: A particulate, precalcined low silica content zirconia, especially one stabilized with yttria, is useful as a catalyst support or as a heat transfer solids component for conducting chemical reactions at high temperature, in oxidizing, reducing or hydrothermal conditions, especially in syn gas operations. An admixture of precalcined particulate low silica content zirconia, particularly a low silica content yttria-stabilized zirconia, is employed in a preferred embodiment as a heat transfer solid, in concentrations ranging generally from about 10 wt% to about 99.9 wt%, with a particulate catalyst, notably a nickel-on-alumina catalyst, in concentration ranging generally from about 0.1 wt% to about 90 wt%. Such an admixture provides a particularly useful catalytic contact mass in high temperature oxidizing, reducing and hydrothermal environments, notably in conducting synthesis gas generation operations. This type of bed promotes continuous, highly efficient heat and mass transfer within the reacting gas phase. The presence of the heat transfer solid as a bed component maintains excellent bed fluidization characteristics, suppressing the normal tendency of the catalyst to sinter or agglomerate; tendencies which promote defluidization of the bed. Moreover, the heat transfer particles of the bed are highly attrition resistant, and are chemically compatible with the catalyst particles of the admixture.
