Patent number: PP4614Abstract: A new and distinct variety of black walnut tree (Juglans nigra L.) which is characterized by rapid growth rate, strong central stem tendency, and outstanding straightness for timber purposes. The nut-bearing habits of this tree are inferior. The pistillate flowers mature very late while pollen maturity is fairly late. In most years there is no overlap in female and male flowering. Flowering begins very late in the life of the tree. The nuts are large and ripen in mid-season. Nut crops occur rarely and are very light. This new cultivar of black walnut tree was discovered by the applicant in Carroll County near Camden, Ind., in a cultivated area. It occurred as a wild tree growing on land managed for timber-growing purposes and was discovered in the course of a search for unique and high quality black walnut trees to be utilized in breeding for outstanding timber qualities. The original tree was cut and sold for high quality veneer.Type: GrantFiled: September 5, 1978Date of Patent: January 6, 1981Assignee: Purdue Research FoundationInventor: Walter F. Beineke

Patent number: 4242759Abstract: There is provided a metacarpal-phalangeal joint replacement having two members, one for insertion into each of the respective bones in the joint. Each member defines a tail and a head, and the two heads are adapted to fit with each other in such a way that when the finger is extended, the joint and thus the finger have a limited degree of lateral freedom to swing from side to side, whereas when the finger is flexed, this lateral freedom is considerably restricted. This variation is brought about by making the face of one head generally protuberant, and the face of the other head generally recessed or channeled. The "match" in contour between the two faces thus varies during the pivoting of the one member with respect to the other, between a substantially complementary fit when the finger is flexed, to a "loose" or "wobble" fit when the finger is extended.Type: GrantFiled: March 12, 1979Date of Patent: January 6, 1981Assignee: Ontario Research FoundationInventor: Robert C. White

-
Patent number: 4242787Abstract: According to the method for joining a fiberglass plastic rod to a metal fitting of an electrical device, a bore is first provided in the metal fitting, the diameter of said bore being somewhat greater than that of the fiberglass plastic rod. One of the rod's ends is then installed in the bore, and the gap defined between the bore formed in the metal fitting and fiberglass plastic rod is filled with a porous material. The whole is then compressed by using the pulse loading technique. The use of pulse loading for joining the fiberglass plastic rod to the metal fitting makes it possible to develop a high pressure in the zone of the joint without destroying the rod; this task is facilitated by the presence of the porous layer between the rod and metal fitting. Compression by pulse loading does not necessitate the use of expensive equipment, nor does it impose stringent accuracy requirements upon the elements to be joined.Type: GrantFiled: August 7, 1978Date of Patent: January 6, 1981Inventors: Andrei A.

Patent number: 4242789Abstract: A magnetic encoding device and method for making the same are provided for use as magnetic storage mediums in identification control applications which give output signals from a reader that are of shorter duration and substantially greater magnitude than those of the prior art. Magnetic encoding elements are produced by uniformly bending wire or strip stock of a magnetic material longitudinally about a common radius to exceed the elastic limit of the material and subsequently mounting the material so that it is restrained in an unbent position on a substrate of nonmagnetic material. The elements are spot weld attached to a substrate to form a binary coded array of elements according to a desired binary code. The coded substrate may be enclosed in a plastic laminate structure. Such devices may be used for security badges, key cards, and the like and may have many other applications.Type: GrantFiled: March 16, 1979Date of Patent: January 6, 1981Assignee: The United States of America as represented by the United States Department of EnergyInventor: Richard J.

Patent number: 4242790Abstract: An electrical contact (10) for an electrical connector including a sleeve (20) and a plurality of axially-aligned fine wires (30), with each wire having an acutely angled end portion (32) at one end thereof and with the plurality of wires secured together at the other end to form a bundle (40). Preferably, the wires are secured together by a weld (50) formed by a capacitor (210) discharging across a gap (300) to the wires, although other securing methods could be used. The bundle (40) of wires then may be inserted into the sleeve of the contact (10) with the angled ends (32) forward in the sleeve (20) and the weld (50) rearward in the sleeve. Said sleeve then is crimped inwardly (25) forward of, or including, the welded portion, to hold the bundle (40) in place within the sleeve.Type: GrantFiled: September 28, 1978Date of Patent: January 6, 1981Assignee: The Bendix CorporationInventors: Dennis L. Ellingson, Paul D. Niles, Richard W. Normann, Theodore L. Wilklow

Patent number: 4242791Abstract: Disclosed is a method for fabricating very high performance semiconductor devices, particularly bipolar-type transistors having a heavily doped inactive base and a lightly doped narrow active base formed by ion implantation. In order to prevent the high dose boron implantation, for an NPN transistor, from getting into the active base region, a self-aligned mask covering the emitter contact i.e., active base region, is required for inactive base implantation. The self-aligned mask is anodically oxidized aluminum pads. The device wafer metallized with blanket aluminum film is immersed in a dilute H.sub.2 SO.sub.4 solution electrolytic cell which selectively anodizes only the aluminum lands situated over the Si.sub.3 N.sub.4 /SiO.sub.2 defined device contact windows. The aluminum oxide formed by anodization process is porous but may be sealed and densified. The aluminum film that is not anodized is then selectively etched off using either chemical solution or sputter etching.Type: GrantFiled: September 21, 1979Date of Patent: January 6, 1981Assignee: International Business Machines CorporationInventors: Cheng T.
