Abstract: A sprocket having a slot formed therethrough can be disposed about the non-rotating support rod of a given roller door. This sprocket is then attached to the door-supporting frame such that the sprocket is positioned externally to the roller door. A connector can serve to effect this attachment. This connector might comprise a plurality of bolts with support sleeves. By this approach, the sprocket can be maintained at a fixed distance from the door supporting frame. This connector might also comprise an adjustable connector that adjustably and fixedly connects the sprocket with respect to the door-supporting frame. By one approach, the sprocket connects directly to the door-supporting frame. By another approach, if desired, the sprocket connects to a frame interface which connects, in turn, to the door-supporting frame. This frame interface can itself also have a slot formed therethrough to again facilitate placing the frame interface into an installed position.

Abstract: Resealable caps and tops for directional pour spout containers currently available for liquid and semi-solid products are either a spout and cap design, in which the tip is cut off to pour or squeeze out the container contents, or a non-spout, hinged top-and-bottom design, which defines a flat surface with an opening. These designs have many limitations. For example, the closure portion of a conventional spout closure can become detached, leading to production line delays, lost tips in transit, product recall at the store level, loss of shelf life and potential chocking hazards to children and pets. The non-spout hinged, top-and-bottom design does not offer the directional dispensing capabilities. This invention addresses the shortcomings of conventional caps and tops by providing a one-piece directional pour spout container cap in which the base has an upwardly directed spout and a hinged flip top cap is attached to the spout.

Abstract: A rotary seal is provided that operates hydrodynamically in response to relative rotation even when subjected to exposure to a high fluid pressure from either side, and provides low breakout and running torque. A dynamic sealing lip having a wavy geometry provides hydrodynamic lubrication in response to relative rotation when little or no differential pressure is acting across the seal. When differential pressure exists, controlled fluid pressure-induced distortion results in a distorted dynamic sealing lip configuration that is suitable for hydrodynamic lubrication, regardless of which direction the differential pressure acts from.

Abstract: A lightweight carrier for aiding in transporting an elongated load such as one or more surfboards or sailboards either uncovered on in carrying bags is formed of a simple U-shaped frame of polyvinyl chloride (PVC) pipe having attached wheels. The carrier which is normally fastened to one end of the load, includes a padded cross member which carries much of the load and padded upright supports or arms which are sufficiently flexible that they can deform or bend outwardly or inwardly. A strap is used to pull the tops of the arms together around the load. A surfer can then carry the opposite end of the load which will trail behind him on the carrier.
