Abstract: An Amelanchier laevis tree having exceptionally vigorous growth, reaching twice the height of prior known Amelanchier laevis trees during the same growth period, the growth being tall and narrow, blooms exhibiting long, drooping racemes with many white flowers, new foliage of dark, reddish orange color becoming thick and dark green, as they mature, with resistance to hot, humid weather.
Abstract: An interspecific F.sub.1 hybrid of the species Cornus kousa and Cornus florida exhibiting large overlapping white bracts and floriferous in a period from about May 18 to about June 3, the floral display ending about the time plants of C. kousa begin their floral display, plants of this cultivar being similar to its seed parent, C. kousa, as regards its upright vase shaped habit when youngbut intermediate plants of the two parent species in the nature of the overwintering flower budds, together with freedom from infestation by dogwood borer and "dogwood decline".
Abstract: A hybrid of Cornus kousa Hance and Cornus florida L. providing a new large-bracted dogwood, which is an exceptionally vigorous, highly floriferous, small, flowering tree, more nearly like C. kousa, being upright in habit rather than low and spreading like C. florida, yet more fully branched and spreading as compared with C. kousa and having a period of floral display that is intermediate to C. florida and C. kousa, exhibiting highly textured, rounded and overlapping white floral bracts that are larger than those of either parent plant.
Abstract: A hybrid of Cornus kousa and Cornus florida providing a new large-bracted dogwood, which is a vigorous, highly floriferous, small, flowering tree, more nearly like C. florida, the plant being low and spreading rather than upright as C. kousa, yet more densely branched and foliaged close to the ground as compared with C. florida and having a flowering period intermediate that of the parental species.
Abstract: An interspecific hybrid of Cornus kousa and Cornus florida, which is a large bracted, vigorous, highly floriferous, flowering tree, most nearly like its parent C. kousa, which plant is upright rather than low and spreading as in C. florida, the instant plant being more fully branched and spreading as compared with C. kousa, with a period of floral display that is intermediate to C. kousa and C. florida, exhibiting attractive pink bracts unlike those of any other hybrid of C. kousa.times.C. florida.
Abstract: An electric rotary machine (for example, a dynamoelectric machine) having a superconducting rotor is disclosed in which an outer shielding member for protecting a superconducting field winding from the influence of the magnetic flux from the stator side and for interrupting heat radiated from the normal temperature side is made of a nickel alloy containing not more than 0.3% carbon, not more than 1% silicon, not more than 2% manganese, not more than 1.5% titanium, from 2 to 8% aluminum, from 8 to 40% copper, and not less than 55% nickel for the balance by weight. The nickel alloy has a structure that a .gamma.'-phase precipitation is formed by aging in an austenitic matrix, and is non-magnetic at 20.degree. C.
Abstract: Stretched surface recording disk (SD) 10 comprises an annular support 12 having raised annular ridges 42 and 28 at its inside and outside diameters 22 and 30 with a base portion 24 in between the two ridges, and an annular recording medium film 14 held in radial tension and stretched across the base portion by adhering the film to attachment surfaces 48 and 36 near the inside and outside diameters respectively. The SD is annealed twice .[.duringmanufacture.]. .Iadd.during manufacture .Iaddend.to relieve stress in the stretched film 14. This annealing results in SD essentially free from track anisotropy and stress distribution anisotropy in the plane of the disk. As a result, data tracks are more stable than in previous SD, track density can be greater, and the SD is generally more reliable.

Abstract: A peptide of the formulaR--Lys--Lys--Glu--Asp--Asn--Val--Leu--Val--Glu--Ser--His--Glu--Lys--Ser--Le u--Gly--Glu--Ala--Asp--Lys--Ala--Asp--Val--Asp--Val--Leu--Thr--Lys--Ala--Ly s--Ser--Gln--OHwherein R is H, H--Tyr-- or R.sub.1 --Pro--Arg--, R.sub.1 is H, H--Tyr-- or R.sub.2 --Ala--Gly--Ser--Gln--Arg--, and R.sub.2 is H, H--Cys-- or H--Tyr--, or a salt thereof, is useful for assaying human parathyroid hormone (h-PTH).
Abstract: In a secure communications system, a key number which is changed periodically, e.g. monthly, and a random number from a random number generator are combined and used as a seed to reset a PN sequence generator, with the output of the generator being used to control encryption of transmission data in a signal processor. The key is also provided to a first encipherer to encipher the random number for transmission with the encrypted data. At the receiver, the key is provided on common to a decipherer for deciphering the random number and a PN sequence generator which is periodically reset by the combination of the key and random number in the same manner as in the transmitter. The PN sequence is then used to decrypt the information. User identification codes are stored in the transmitter and are used to encipher the key, with each employing its ID code to decipher the key. The user ID codes are known only to the system operator, so that not even a particular user can know the key.
