Abstract: ABSTRACT OF THE DISCLOSURE                  There is disclosed a continuous process for refining whole grain corn to obtain a prime corn starch fraction, an animal feed product and, optionally, corn oil.  The process comprises dry milling corn kernels to provide an endosperm fraction, a germ fraction, a fiber (hull) fraction and a clean-ings fraction, wet milling the endosperm fraction including using two distinct steeping steps, one upstream and the other downstream of an impact milling step, to provide a mill starch slurry.  The process further comprises removing fine fiber tail-ings from the mill starch slurry, separating the slurry into a starch-rich fraction and protein-rich fraction, concentrating the protein-rich fraction, directly combining the fiber (hull), cleanings, fine fiber tailings and protein-rich concentrate without removing corn oil therefrom, with the germ fraction to provide a wet animal feed product, and drying the feed product.      Optionally, corn oil is recovered from the germ fraction only.

Abstract: ABSTRACT OF THE DISCLOSURE         An assembly for sealing an interface between a high pressure steam chest and a casing, wherein high pressure steam flows from the steam chest into the interior of the casing.  The assembly comprises a sealing element extending through the interface for preventing direct contact between the high pressure steam and the interface, and joined to the steam chest so that a steam tight joint is developed therebetween.  The assembly further comprises a chamber defined by the steam chest, the casing, and the sealing element in communication with the interface between the steam chest and the casing; a first passageway having one end in communication with the interior of the casing and a second end in communication with the chamber, for passing steam from the interior of the casing to the chamber; and means for developing a pressure differential across the first passageway so that the steam pressure at the second end of the passageway is less than the steam pressure at the first end of the passageway.  A low pressure region is provided having a steam pressure lower than the steam pressure in the steam chest; and a second passageway is provided, having one end in communication with the chamber and a second end in communication with the low pressure region for passing steam from the chamber to the low pressure region.

Filed: 1979-06-01
Granted: 1980-09-23
Abstract: ABSTRACT OF THE DISCLOSURE           Metal working operations, especially drawing, are facilitated by applying to the metal a composition which provides lubricity thereto and which melts at about 30-100°C.      The composition preferably comprises an ester of a carboxylic acid, with a carboxylic acid or derivative thereof, a phospho-rus acid salt and an antioxidant being preferred optional ingredients.  The composition may be applied in liquid form and solidifies on cooling to ambient and normal storage temperatures.  Prior to application, the composition is preferably heated to a temperature higher than its melting temperature for ease of flow and uniform dispersion thereof onto the metal.  In a preferred method of application, a reservoir is located beneath the composition applicator and composition is pumped therefrom to the applicator, preferably a roller coater, with excess composition being recirculated.         Steam may be used both to heat the composition to melting point and purge the pump and circulation piping at the start and finish of each run.

Abstract: ABSTRACT OF THE DISCLOSURE      A composite container is disclosed that includes a helically-wound label layer which contains a line of perforations that extends circumferentially adjacent and spaced from a metal end closure member, thereby to define a line of tear along which the label layer may be torn from the container.  By the provision of the perforated tear line, the requirement of a circumverential collar cut in the container is avoided, thereby permitting the use of a thinner fibrous body wall layer.  Preferably the line of perforations is discontinuous to define an imperforate portion of the label layer which is bonded in straddling relation across the helical butt joint contained in the fibrous body wall layer.

Abstract: MECHANICAL TELEPHONE CONVERSATION TIME           LIMITING DEVICE           ABSTRACT OF THE DISCLOSURE    To prevent unauthorized or prolonged telephone conversations, a limiting device is attachable to an ordinary telephone set by means of a padlock means with removable key. The device comprises a timer which can be set only when one of the shut-off pushbuttons of the telephone set is depressed. A knob is provided for setting the timer which is enabled to rotate a rotatable member of the timer only after the knob has been depressed. The knob is arranged such that this depression also involves the depression of one of the pushbuttons. The timer is also operative to depress either push-button as the preset conversation time expires. With such a device, it is not possible to reset the timer or retard the movement of the timer in order to prolong the conversation time, because such an attempt would unavoidably result in one of the pushbuttons being depressed on the telephone set and the communication being therefore interrupted.

Abstract: ABSTRACT OF THE DISCLOSURE   A zero or low insertion force electrical connector is provided by a pair of elements which may be fitted together along a longitudinal insertion axis, and then engaged in edge contact relationship at at least two points by a relative pivoting movement.  The elements may be fabricated of relatively thin sheets, and have a total thickness corresponding to only two thicknesses of the material.  Connectors in accordance with the invention may be made of identical or dissimilar elements, and may include means for preventing out-of-plane shifting of one element relative to the other.  Because of the thin edge profile, the elements may be densely packed in a multiple connector, and be-cause of the hinging action the connectors may provide structural support for circuit boards or conductors to which they are coupled, or enable access to circuits for testing under an applied voltage.

The random word encrypted under the asserted key KA is stored in said U/I Terminal and the random word encrypted under the true key KT is stored in the CARD.  The U/I terminal then causes the encrypted word stored in the CARD to be transferred to the U/I Terminal and the two encrypted words are compared for identity.  If the comparison is true, the holder of the card has entered the correct asserted key KA into the system, and his identity is presumed to be true.
