Abstract: Methods and apparatus for cleaning a central venous catheter port are disclosed. An apparatus includes a body, a coupling configured to connect the body to the hub, a cleaning cap coupled to the body, and an actuator disposed within the body for rotating and translating the cap relative to the hub. The cleaning cap includes a cap body defining a cavity and a cleaning member disposed within the cavity, the cleaning member having threads that engage with the threads on the hub.

Abstract: A method for forming a multi-component composite metallic tube, in particular, a bi-component metallic tube, comprises the steps of forming a coextrudable, multi-component billet including an inner component formed from a first metallic material, and an outer component formed from a second metallic material. Notably, explosive bonding is employed for bonding the first and second components to form a metallurgical bond at the interface thereof, thus forming the desired multi-component billet. The multi-component billet is subsequently heated, and coextruded to form a multi-component tubular structure, having a metallurgical bond at an interface between inner and outer layers of the composite metallic tube.

Abstract: Coating compositions which contain a mildew-controlling amount of an isothiazolone are stabilized against chemical decomposition of the isothiazolone by the addition of formaldehyde or a compound which releases formaldehyde under basic conditions.

Abstract: A method of coating marine structures including marine vessel hulls is disclosed, the method comprising painting the surfaces of the structure to be exposed to fouling conditions in salt water including sea water and brackish water, with a paint containing certain 3-isothiazolones in an amount to control marine plant and animal life such as algae, hydroids, and barnacles.

Abstract: Coating compositions which contain a mildew controlling amount of an isothiazolone are stabilized against chemical decomposition of the isothiazolone by the addition of a metallic compound. Among the compounds which can be used are the acetates, carbonates, chlorides, bromides, nitrates, sulfates, phosphates, and oxides of cadmium, cobalt, copper, lead, manganese, mercury, nickel, silver and zinc.
