A blood vessel clip applicator preferably includes two twist pins at one end, between which a blood vessel is placed before occlusion. A magazine in the blood vessel clip applicator preferably holds a plurality of blood vessel clips and can be rotated independently from a grip assembly, whereby the twist pins can be rotated to compress a blood vessel held between them. A blood vessel clip is preferably placed on the blood vessel after it has been flattened.

A blood vessel clip preferably comprises spring quality material, and preferably has a head connected to a first leg and a second leg. The magazine preferably has a constricted region adjacent to an exit aperture. As the head enters the constricted region, the compressive force exerted on the head by the constricted region opens the blood vessel clip to an open position.

In an alternate embodiment, a plunger applies a blood vessel clip with a direct stroke. The plunger has a plurality of stepwise indentations used to restrain the blood vessel clips before application and for pushing them all forward substantially simultaneously during application.

In an alternate embodiment, a variety of blood vessel clips having different shapes, cross-sections and grooves are suitable for use with the blood vessel clip applicator. The alternate blood vessel clip preferably have two legs in a “V” configuration and a head connecting the two legs. The constricted region compresses the head of the blood vessel clip as it passes through the constricted region, thereby closing the clip onto the blood vessel. These alternate embodiments may comprise substantially annealed metal.

Amino alkoxy-modified silsesquioxanes (amino AMS), and/or amino co-AMS compounds that also comprise a mercaptosilane or a blocked mercaptosilane, are excellent adhesives for coating plated or unplated metal wire for adherence of the wire to a rubber stock. The amino AMS and/or the amino/mercaptan co-AMS adhesives can be used with all types of rubber and there is no requirement for the use of special adhesive additives to the rubber vulcanizates, such as, but not limited to, cobalt, resins and high sulfur levels. In particular, the use of amino AMS and/or amino/mercaptan co-AMS compounds as adhesives for bonding wire to rubber also improves the adherence performance of the reinforcements to obtain sufficient bonding that is resistant to degradation over the course of time, especially resistance to thermal aging and/or thermo-oxidizing aging, in particular corrosion in the presence of water.

The invention provides a method of manufacturing golf balls composed of a core and one or more cover layer which encloses the core, at least one cover layer being a thin layer having a thickness of 1.0 mm or less. The thin layer is formed to a desired thickness on a surface of a core or spherical body by holding within a mold cavity the core or a spherical body composed of the core enclosed by a cover layer and injecting a synthetic resin material into a space defined by a surface of the core or spherical body and an inner face of the mold cavity so as to form a cover layer on the surface of the core or spherical body, then grinding the resulting cover layer to a thickness of at least 0.1 mm with a specific type of grinder. Golf balls obtained in this way can be provided with a good sphericity even when the cover is formed to a very small thickness.
