A method and apparatus for processing leather hides utilizing a generally conventional first processing apparatus adapted to continuously process one-half only of the area of a leather hide, wherein a second processing apparatus identical in function to the first apparatus is provided in tandem, and wherein a hide is processed by first processing one-half only of the area of the hide utilizing the first apparatus and conveying the hide to the second apparatus for processing the other half of the...

An input signal is supplied through a plurality of band-pass channels which selectively apply different amplifications to signals therein. Frequency adjustments in individual channels as well as between channels is provided. A composite signal is formed from the various channel signals which enhances signal detection. The electrical characteristics of the various channels is determined by interfering spectrum in which the input signal resides.

An apparatus and a method for handling the unwinding end of a wound body of yarn by releasing the end from adjacent winds of the yarn and, with the bobbin rotating, picking up and carrying the released end in a stream of air flowing into a suction nozzle. Lips of the suction nozzle automatically conform to the configuration of the body of yarn. One of the lips may engage the body to aid in releasing the end from the body and providing an air seal, and the other lip may be spaced from the body, t...

A computer system includes a high-capacity storage for storing a set of information, additional information-handling means for handling a subset of information selected from the set of information, and a truncated relay tree. In reading stored information, the large end of the truncated relay tree is normally the input end and is connected to the high-capacity storage; the small, truncated end is normally the output end and is connected to the additional information-handling means. The number of...

A method of bleaching discolored mineral comprising forming an aqueous slurry of said mineral, adding a small amount of water soluble sodium hypochlorite and a small amount of hydrogen peroxide to said slurry and then adding a water soluble hydrosulfite to said slurry.

An apparatus and a method for readying filled supply bobbins for receipt by a winding machine. As each bobbin is delivered to the apparatus it is given a preliminary servicing and inspection, whereupon the bobbin is either rejected or further processed by having a tailing or inner end of the body of yarn severed and an unwinding or outer end of the yarn picked-up and formed into a bunch which is deposited by means of a ram in a hollow core of the bobbin for retention therein until subsequent ret...

A method and apparatus are provided for extracting the adductor muscle from scallops. Scallops are subjected to a heat shock and are then mechanically agitated to disengage the muscle and attached viscera from the shell. The muscle and viscera are removed from the shells and separated from unfragmented portions of the shells on a vibrating screen and are then contacted with water before being separated from small shell fragments by flotation in a brine solution. Viscera is removed from the muscl...

An apparatus and method for processing elongated cup-shaped workpieces through one or a plurality of modular processing units, each of which incorporates a plurality of fluid streams oriented to impinge against the surfaces of the workpieces, thereby effecting a conveyance of the workpieces through the apparatus and a concurrent treatment of the interior and exterior surfaces thereof.
