Abstract: An Offshore Personnel Transfer System moving men and materials between an offshore platform, or any oil and gas facility such as semi-submersibles, jack-ups, and the like, and a workboat is disclosed. The system does NOT require any special equipment on the workboat and is self powered deriving its energy from standard energy sources found on offshore facilities. Furthermore the system is comprised of standard off-the-shelf components.

Abstract: A retrofitable wind screen for portable gas cookers. The device, made of sheet metal, readily adjusts to fit almost any portable gas cooker and fits around the outside of the cooker frame extending a minimum of three inches above the cooker grate. The device shields the gas flame from the effects of wind and increases the overall cooking efficiency of a gas cooker. Finally, because the device extends above the cooking surface, it provides a measure of safety by preventing the accidental movement of a cooking utensil from the cooking surface.

Abstract: A retrofitable passenger/cargo carrier unit for standard utility golf carts is disclosed. The passenger/cargo carrier unit is designed to be retrofitable to any passenger type golf cart and is mountable to the cart without drilling holes in the cart through the use of adjustable clamps which hold onto existing support tubes found such carts. The carrier unit converts readily between a cargo carrier and passenger carrier which is capable of carrying up to two extra passengers. The passengers are seated parallel to the direction of motion of the cart and passenger additional safety is provided by a rear gate. A "swing-away" clamp is disclosed for use with the passenger/cargo carrier which allows the existing golf bag holder assembly to swing out of the way of rear passengers or cargo; thus assuring the functionality of the carrier. Further a rear canopy for the protection of rear passengers or cargo is disclosed which attaches to the carrier.

Abstract: A cooling cover (10) has an air inflatable pad (16) which may be positioned within a pocket (20) of a coverlet (18). The pad (16) formed of air impermeable material has plenum chambers (28) at opposite ends thereof, and a plurality of individual longitudinally extending passages (26) extend between the plenum chambers (28). Openings or air orifices (34) of a non-uniform pattern in the lower rounded surfaces of the inflatable pad (16) direct cooling air in a plurality of small air jets onto the body of a user of the cooling cover (10). A source of cool air (21) is connected to the inlet (30) for a plenum chamber (28) to deliver cool air to the pad (16).

Abstract: A rotatable planter and a method of producing such planter wherein the planter includes a thermoplastic tube with a plurality of pockets therein, a bottom and means for supporting the tube so that it is rotatable either by the wind to which it is exposed or by a stand on which it is supported. The improved method includes the steps of cutting a plurality of radial slots in a tube of preselected length, heating the area above and below each slot and forming the upper portion of the pocket above the slot inward and forming the lower portion of the pocket below the slot outward.

Abstract: A fluid injector suitable for injecting a fluid into a flowline having a fluid under pressure therein in which a piston divides the interior of a hollow body into a power chamber and a pumping chamber with a piston rod extending through the pumping chamber to the exterior of the body, fluid filling the pumping chamber, a discharge line from the pumping chamber through a valve to the flowline, and a supply line from the flowline to the power chamber, the valve in the supply line being controlled by the timed position of the piston. A method of injecting a fluid into a flowline including the steps of delivering pressure fluid from the flowline to a pressure responsive position displacement pumping means, delivering fluid from the pumping means through a valve to the flowline and controlling the valve to control the amount of fluid pumped responsive to the timed position of the pumping means.

Abstract: A protection structure for a tubular member, such as a blast joint, and a protection element therefore which is an abrasion resistant half sleeve with an inward facing tongue and groove along one axial edge, an outward facing tongue and groove along the other axial edge, a groove in one arcuate end and a projection on the other arcuate end, two of said elements forming a protection ring and a plurality of said rings being supported on a tubular member by upper and lower supports which provide tongue and groove engagement with the upper end of the upper ring and with the lower end of the lower ring.
