Abstract: A blade dispenser includes a housing with a bottom and sidewalls defining a blade storage. A lid covers an entry opening and is movable in relation to the blade storage to provide access to the entry opening for arranging blades in a stacked configuration into the blade storage. A protrusion protrudes from a sidewall into the upper part of the blade storage in a first part of the blade storage. A latch protrudes from a sidewall into the upper part of the blade storage in a second part of the blade storage, the protrusion and latch have contact surfaces preventing the spring force from moving blades out of the blade storage via the entry opening. An exit opening at a sidewall of the housing allows a blade to pass through the exit opening out of the blade storage.

Abstract: Systems and apparatuses include a tubular body of a garden hose assembly. The tubular body includes an inner tube including an inner surface and an outer surface, wherein the inner surface defines an interior passageway of the garden hose assembly. The tubular body further includes an outer tube including an inner surface and an outer surface, wherein the inner surface surrounds the outer surface of the inner tube. The tubular body further includes a reinforcement layer including a helical pattern spiraling in at least one direction around the outer surface of the outer tube. The tubular body further includes an inner cover including an inner surface and an outer surface, wherein the inner surface surrounds the reinforcement layer. The tubular body further includes an outer cover including an inner surface and an outer surface, wherein the inner surface surrounds the outer surface of the inner cover.

Abstract: A method for determining the oil and grease concentration of aqueous solutions on offshore facilities without having to ship the aqueous solutions to shore-based laboratories for analysis. The method generally involves a liquid-liquid extraction procedure, where a concentration of oil and grease extracted from a known volume of aqueous solution is determined using a pair of weighing devices, which are connected to a common computer which is capable of processing synchronized data points received from the two weighing devices. The first weighing device is a control scale upon which a reference mass having a known weight is placed. The second weighing device is a sample scale upon which the extracted oil and grease will be placed.
