摘要:
An anti-biofouling seismic streamer casing (100,100′) is provided that is formed by a flexible tubing (110) coated with a layer of a two-part heat cured silicone elastomer (120). The seismic streamer casing (100, 100′) is formed by a method that includes steps of providing a flexible tubing (200) and pre-treating the outer surface of the tubing (210). Two parts of a two-part silicone elastomer are then mixed together (220). The method also includes coating the mixed two-part silicone elastomer on the flexible tubing (230), and heating the flexible tubing to cure the coating (240).

An optically clear biofouling resistant coating compositions specially formulated for very high light transmission and more particularly coating compositions which can be applied to marine instruments and sensors. The compositions provide a biofouling resistant coating on the surface of the marine instruments and sensors which prevents underwater organisms from adhering and growing on the surfaces of the structures over a long period of time.

A portable kneeling support pad used protect the user's knees and to stress on the knees when kneeling or standing up from a kneeling position. The support pad includes a flat rectangular base with a chemical resistant, resilient top surface. Attached near one end of the base is a perpendicularly aligned support pole with a perpendicularly aligned hand grip attached to the end of the support pole. The base includes a support pole bore with a coaxially aligned stub. The stub is perpendicularly aligned with the top surface of the base and designed to engage the support post. Disposed around the upper end of the stub is an adjustable clamp that enables the user to selectively rotated the support pole 360 degrees around the stub and slide the support pole over the stub to decrease or increase the height of the hand grip over the support pad.
摘要:
A convertible elongated stepping bench configured to be uses as a standard step stool or a low profile sitting or kneeling platform. The bench includes an elongated rectangular, lightweight rigid frame with two opposite leg assemblies. Each leg assembly includes two pivotally attached rigid legs. Each leg is pivotally attached to a corner of the rigid frame. The leg assemblies pivot between a diagonally downward position that supports the rigid frame in an elevated position over the ground or fold inward, under and rigid frame. Attached to the outside surface of each leg near the pivoting hinge is a foot pad. Extending downward from the bottom surface of the rigid frame are at least two leg stops. When the legs are folded inward, the distal end of each leg rests against a leg stop so that the leg's axis is parallel to the rigid frame's longitudinal axis. When the leg assemblies are folded inward and the bench is placed on the ground, the feet pads on the legs supports the bench on the ground.
