Abstract: A retaining wall has at least two facing panels in a tier adjacently interconnected by at least a pair of panel interconnectors mounted to the inner surfaces of the panels to allow adjacent panels to rotate relative to each other. Horizontal flexible anchoring devices, which include rigid anchors flexibly or rigidly connected to the panel interconnectors, connect the facing panels to an earth mass. The panels may tilt, or horizontally deform, relative to deformations in the earth mass. Front horizontal panel adjustment devices allow the tension of the connection between the flexible anchoring devices and the panel interconnectors to be varied from the front of the wall to allow horizontal alignment of the panels after the earth wall has been built. An adjustable inner panel supports the facing panels prior to the start of earth wall construction. Geofabric layers, independent of the flexible anchoring, are used during construction to stabilize the earth wall.

Abstract: A bowling lane dressing apparatus is provided which has a carriage for movement along the bowling lane between the foul line and the pit. Drive wheels are rotatably mounted on the carriage for moving the carriage along the bowling lane by means of drive means connected thereto. A lane buffer roller is journaled on the carriage in lane-contacting relation which extends transversely to the direction of travel. A reservoir is mounted in the carriage for storage of lane-dressing fluid. A transfer roller is mounted in rolling engagement with the lane buffer roller and in fluid communication with the reservoir for transferring fluid from the reservoir to the lane buffing roller. Variable speed drive motor is connected to the drive wheels for rotating them at variable speeds to vary the speed of the carriage as it moves along the bowling lane to vary the rate of transfer of fluid to the bowling lane surface by the lane buffer roller.

Abstract: A ribbon guide for use with a dot matrix printer having a printhead traversable along a path parallel to a printing platen and which includes means for selectively shifting the ribbon guide to one of several positions. The ribbon guide includes a central body portion which pivotally mounts on pivot pins to the printhead. A pair of faceted ring segments are formed on the central body portion for supporting the ribbon as it passes through the ribbon guide and over an opening in the central body portion adjacent to the printhead. The central body portion is also formed with a pair of support members at opposite ends each having a faceted outer surface for contact with the printing paper. In addition, the support members include a slit for releasably securing an endless loop of ribbon to the ribbon guide to allow field replacement of a ribbon guide.

Abstract: A coupling assembly is provided including a pair of confronting conduit members. Each conduit member has an annular flange fixed to the confronting ends of the conduit members. A circumferentially extending coupler surrounds portions of the flanges. A resilient bonding jumper transversing the circumferential wall of the coupler provides electrical continuity between the conduit members. The bonding jumper includes a body portion and a pair of arms fixed to opposite ends of the body portion. The arms extend in opposite directions. When the coupler is secured to the flanges, each arm contacts one of the flanges and a torque is produced tending to force the other arm into secure electrical contact with its contacted flange.
