摘要:
An acoustical stringed instrument includes a body, which has a top member having a generally flat forward part. The body also has a back member which includes a side wall with an upper section and a lower section and an inner side wall surface generally perpendicular to the forward part of the top member. A neck member of the instrument has an elongated upper portion extending upwardly from the upper section of the body side wall. Additionally, the neck member has an elongated lower portion extending through the interior of the body between the upper section and the lower section of the side wall and spaced rearwardly of the forward part of the top member. The elongated lower neck portion has an upper mounting means fixed to the inner side wall surface at the upper section of the body side wall, and a lower mounting means fixed to the inner side wall surface at the lower section of the body side wall.
摘要:
A top member for the body of an acoustical stringed instrument includes a forward part having an interior portion spaced inwardly from the side wall of the body after the top member has been assembled to the body, the interior portion having a pair of composite material layers with a core layer bonded therebetween. The forward part further has a core free flex edge portion which borders the outer periphery of the interior portion, and is made by having the pair of composite material layers bonded in contact with each other. A skirt projects rearwardly from the rear surface of the flex edge portion and extends along the edge of the flex edge portion. When its top member is assembled with the body, the skirt slidably fits over the sidewall of the body.
摘要:
A liquid anticorrosion composition adapted for application to ferrous tubular goods is provided comprising an aqueous solution of cyclohexylammonium benzoate and a benzoate salt, which is preferably prepared by reacting cyclohexylamine with excess sodium benzoate in an aqueous alcohol solvent. A sealable thread protector end cap which protects the precisely machined threads from physical abuse and which isolates or seals from the environment the corrosion inhibitor composition is also provided.

A surgical cutting instrument includes an electrically heated cutting edge and a power supply system for maintaining the cutting edge at a constant high temperature for sterilizing the blade, cutting tissue and cauterizing the incised tissue to reduce hemorage from the cut surfaces of the tissues (hemostasis).
