Abstract: An apparatus and method for deboning or filleting the meat from a poultry breast section which is characterized by a plurality of mandrels spaced along a moving endless chain conveyor and each adapted to receive a poultry breast section. After loading of the mandrel, it is advanced to a cutting station comprising a pair of closely spaced stationary knives disposed parallel to the direction of travel. The knives effect a longitudinal cut of predetermined depth closely adjacent to the length of the keel or center bone of the breast section to create a loose flap of meat. The mandrel and breast section continue to be advanced to a meat stripping section which comprises a pair of lateral spaced resilient strips which form a downwardly inclined path. As the breast section engages the strip in a predetermined manner, the meat portion on each side of the breast is peeled from the bone as the breast advances through the stripping section. The meat fillet is collected separately from the remaining bone portion.

Abstract: A method for coating tin on an electro-conductive substrate in a bath comprising stannous ions, a mineral acid and a non-ionic surfactant consisting of nonylphenoxypoly (ethyleneoxy) ethanol. A catalyst metal comprising metallic zinc or zinc alloy and the substrate to be coated are immersed in the bath. During this immersion electroconductive contact is effected between the substrate and zinc or zinc alloy. A smooth, pore-free, pure tin coat is deposited on the substrate during the time the substrate is in electro-conductive contact with the zinc or zinc alloy.

Abstract: An improved tuning device for mounting upon stringed musical instruments such as the guitar, banjo, mandolin and the like. The improvement relates to providing a construction wherein the winding spindle or drum upon which the string is attached may be selectively and independently rotated on a one to one basis or on a high multiple to one basis. The one to one turning ratio is designed to be used to initially wind the string from a relaxed condition to a pre-tuned degree of tension associated with replacing worn or broken strings. The multiple tuning basis is, in typical fashion, employed to fine tune the string tension to produce the appropriate musical note.
