Abstract: A fine angular adjustment is provided between a windshield wiper arm and a windshield wiper drive shaft without changing the standard drumhead or drive burr carried by said drive shaft. Provision is made for fine adjusting the angular orientation of the arm by increments of one degree. In two embodiments, the mounting head of the arm is in two parts with the first part fixed to the drumhead of the drive shaft and the second part having incremental teeth being spring urged into contact with mating incremental teeth on the first part, such that actuating the spring separates said incremental teeth of the two parts making it possible to rotate the second part relative to the first part in approximately one degree increments.

Abstract: A recovered soybean protein extract is disclosed containing at least 55 percent of soybean protein, on a dry solids basis, and from 2 to 32 percent of natural soybean oil, based on the weight of the protein. The remainder of the extract includes water, carbohydrates, minerals and proteinate salts. A method for recovering the soybean protein extract, whereby the oil and the protein are jointly separated from the soybean, is also disclosed. The method involves grinding cleaned and dehulled soybeans, slurrying the ground product in peroxide and water, and recovering a protein extract from the slurry by centrifugal processing. An isolate, protein content at least 85 percent, is obtained by adjusting the slurry pH to at least about 8 to solubilize the protein, removing the insolubles and free oil, and then precipitating the protein solids by lowering the pH to about 4.5; the precipitated protein is then recovered from the slurry.

Abstract: The invention is directed to a method and apparatus for processing shelled corn cobs. The cobs are graded, aspirated, and crushed for reducing the length of the cobs to between 1/2 inch and 3 inches. A second aspirator removes any remaining husks and hammer mills reduce the corn cobs into 3/8 inch to 1/2 inch pieces. The pieces are graded and oversized pieces are returned to a hammer mill while the remaining pieces are dried in a drier to reduce their moisture content. After grading, a portion of the pieces are sent through an attrition mill to further reduce the size of the pieces. After aspirating, the pieces are processed through roller mills to further reduce the size of the pieces and then passed through an attrition mill and graded into final product sizes.

Abstract: The invention relates to a wiper arm assembly having a mounting head with a socket adapted to receive a drive burr of an oscillatable pivot shaft, an arm pivotally connected to the mounting head and spring means connected between the mounting head and the arm so as to press the arm toward a windshield. A latch is provided on the mounting head which, in one position, will render the spring inoperative and will remove a retaining member from alignment with the socket so that the mounting head may be assembled on the drive burr or the mounting head may be removed from said drive burr. After the mounting head is pressed on the drive burr, the latch is moved to a second position that will release the spring means so that the spring means can exert pressure on a wiper blade attached to the outer end of the arm.

Abstract: A lock for maintaining the pivotal connection between two parts of a pressure-distributing superstructure in a windshield wiper blade assembly in which the pivotal connection is effected by providing a pair of outwardly projecting lugs on the resilient side walls of one of the parts which nest in a pair of aligned openings in the U-shaped end portion of the other of the parts. The parts are assembled by deflecting the side walls of the one part inwardly into an open space in the one part to permit the U-shaped end portions of the other part to be fitted over the lugs. Thereafter, the resiliency of the side walls urges the lugs outwardly into the openings to pivotally connect the two parts. In order to prevent disconnection of the two parts, the lock is inserted into the open space to prevent the side walls of the one part from collapsing into the open space. The lock has enlarged portions to retain the lock within the open space which has been adapted to receive the lock.
