Title: Method for monitoring hermetically-coated fibers
Inventor: ALLEGRETTO ALLEN E
IPC: G01M11/00
Filed: 1993-12-09
Abstract: ABSTRACT OF THE DISCLOSURE          A method for monitoring the thickness of a hermetic coating on an optical waveguide fiber is provided in which an interference pattern is produced by illuminating the fiber with a laser beam.  A spatial frequency spectrum is generated for the  interference  pattern  and  a  first  component  of  that spectrum, corresponding to the outside diameter of the fiber, is identified.  The magnitude of this component is inversely related to the thickness of the coating, i.e., the magnitude decreases as the coating thickness increases, and thus this magnitude can be used to monitor the thickness of the coating during,  for  example,  the  coating  process.    Effects  of fluctuations in the power of the laser beam and/or movement of the fiber relative to that beam can be minimized by normalizing the magnitude of the first component by the magnitude of the DC component of the spatial frequency spectrum.

Patent CA-2115484-A1 (CA)
Inventor: WELLINGHOFF STEPHEN T
IPC: A23L3/358
Filed: 1994-02-11
Abstract: A process incorporating chlorine dioxide precursors into a polymer or oligomer film that is coated onto various substrates. Controlled release is accomplished by absorption of moisture from the environment. An amine (primary, secondary, or tertiary amines substituted with 2-hydroxy or 2-carboxyamido ethylene groups) is dissolved or suspended into a melt consisting of monomers capable of strong hydrogen bonding. An apolar phase containing a water hydrolyzable acid anhydride or silane terminated acid is then blended with the polar amine containing phase to produce a two phase system of arbitrary degree of dispersion. Reacting dry chlorine dioxide or chlorine dioxide solutions in apolar solvents with the oligomer or polymer film produces an iminium chlorite salt. The chlorine dioxide is released when the iminium chlorite loaded polymer is hydrated by ambient moisture.

Abstract: LUMBER ORGANIZER                   ABSTRACT OF THE DISCLOSURE    A machine  for  aligning  lumber received  from  a previous processing station into an orientation suited for a subsequent processing  station.   The machine has  an  infeed  conveyor for receiving  lumber  from  a previous  processing  station.    Large rotating drums are positioned in the infeed conveyor adjacent to carriers  of  the  infeed  conveyor with  a portion  of the drum periphery extending above the infeed conveyor.  An angled conveyor having multiple carriers, such as belts, is mounted strategic to the infeed conveyor and drums with the second conveyor extending upwardly at an angle to the infeed conveyor and drums.  The drums are rotated such that the peripheral velocity of the drums is greater than the carriers of the infeed and angled conveyor. The drums elevate  (lift) and accelerate the lumber from the infeed conveyor onto the angled conveyor.  The infeed conveyor, the drums and the angled conveyor are cooperatively coupled to align the lumber in the desired orientation as the lumber is lifted and accelerated off the infeed conveyor and transferred to the angled conveyor.  The angle of the angled conveyor may be adjusted to induce the lumber that may remain in a stacked condition as the lumber is transferred from the infeed conveyor to the angled conveyor to slide off one another to separate the pieces of lumber.          An exit conveyor is provided adjacent the angled conveyor for transporting the aligned lumber to the subsequent processing station.

Abstract: A joint, particularly for use with banister assemblies, comprises a ball (14) fixed into position within a socket (13). The balls (14) formed at either end of a plurality of balusters (12), and sockets (13), formed in a base rail (10) and hand rail (11) are preformed at a work shop or factory and subsequently used for construction of a banister assembly. During the construction of such an assembly, the base rail (10) is fixed into position and the hand rail (11) placed in parallel, vertically spaced-apart relation to it, supported loosely by newel posts at either end. Next, balusters (12) are inserted between the base rail (10) and hand rail (11) by inserting a bottom ball of each baluster (12) into the base rail sockets (13) and adjusting the hand rail (11) to enable insertion of the upper balls into the hand rail sockets (13). Once all balusters are in position, the hand rail (11) can be firmly fixed into place. Special connectors (29, 30) are used to enable ajustment and subsequent fixing into position of the hand rail (11), and a special clamp used to assist the formation of the joints where necessary. Replacement ball assemblies (52, 53, 54) are provided to facilitate replacement of broken balusters within existing banister assemblies. Adhesive may be used.

Title: Battery Pack Retention Apparatus
Inventor: SHABABY MICHAEL L
IPC: H04W88/02
Filed: 1994-08-15
Abstract: The battery pack retention apparatus, described herein, is an injection molded part. The injection molded part includes a rear housing (200) for a radiotelephone (100), two rails, (201, 203) for a battery pack (101) to slide along and six guide bars (207, 209, 211, 213, 215, 217) for retaining the battery pack (101) on the radiotelephone (100). Four of the six guide bars are the compliance type. The compliance-type guide bars (207, 211, 213, 217) have a U-shape and are coupled to the rails. A channel (401) is cored out from the rails under the compliance-type guide bars to allow for deflection of the guide bars. Deflection is caused by the bullets (409) of the battery pack (101) when the battery pack (101) is fully inserted. The deflection (y) of the guide bars provides a calculated force upon the battery pack (101). This calculated force ensures a high quality electrical connection between the contacts of the battery pack and the contacts of the radiotelephone.
