Abstract: An optical module is packaged using one or more internal fiber connections which are arranged to minimize the likelihood of internal connection damage when the module is installed on a circuit board. The module includes at least one external connector arranged on a side of the package, and a submount within the package for supporting a component such as an optical source or an optical detector. An optical fiber is connected within the package from the submount to a connector interface of the external connector. The end of the fiber at the connector interface has a preformed connector thereon which engages a ferrule associated with the interface. The other end of the fiber is attached to the submount for optimal coupling efficiency. The fiber may undergo a bend of about 90.degree. or 180.degree. from its first end to its second end. In order to accommodate the fiber bend, the component submount is positioned within the package in a location remote from the external connector.

Abstract: A coupling member for detachably connecting together two sections of air brake hose between railroad cars. Each coupling member has a hollow tubular body with one end attached to a section of hose and with an opposite end having an arcuate body portion extending circumferentially about and outwardly of the tubular body, and has an arcuate locking lug extending generally axially from the body concentric with the arcuate body portion. An L-shaped arcuate flange projects outwardly and forwardly from a rear portion of the tubular body and is provided with a lip which engages a similar lip formed on the arcuate locking lug of the other of two coupling members to secure the members in coupled position. An elastomeric gasket is mounted within the bore of the tubular body and forms an airtight seal with a similar gasket mounted on the other coupling member. A finger is pivotally mounted within a radially extending slot formed in an arcuate end body portion of the tubular body.
