Abstract: This invention relates to a new and distinct variety of miniature rose plant primarily distinguished by very double bright red flowers of carnation-like form borne in clusters and by the exceptionally long lasting quality of said flowers.

Abstract: A rose plant of the Floribunda class is provided having abundant long lasting double flowers which are lemon yellow suffused with buttercup yellow. The seed parent of the new variety was the variety Poppy Flash and the pollen parent resulted from the crossing of the variety Meiridge with the variety Allgold. The vegetation of the new variety is vigorous.

Abstract: This novel rose variety is a mutation of Mercedes and differs therefrom in its blossom colors which are of a more orange red than that of the parent variety.

Abstract: A new and distinct variety of Pink Flowering Dogwood, botanically known as Cornus florida is provided. The new variety exhibits a rapid upright growth habit and most nearly resembles the Sweetwater Red Flowering Dogwood (non-patented), but primarily is distinguished therefrom by the distinctive coloration of the foliage (as illustrated). The foliage initially is light purple and changes to dark purple as the leaves mature. Such foliage coloration substantially is retained throughout the growing season and into the fall even when grown in full sunlight.SUMMARY OF THE INVENTIONThe new and distinct variety of Pink Flowering Dogwood tree was discovered in 1966 while growing within a block of approximately 250,000 Cornus florida seedlings on the cultivated nursery property of the assignee located near McMinnville, Tenn. The seed which yielded the new variety was planted in 1965 and likely was obtained from either the Pink Flowering Dogwood variety or the Sweetwater Red Flowering Dogwood variety.

Abstract: An outer tube has a hollow elongated member, attached to one end of the tube in a coaxial relationship. A rod slidable in the tube causes a replaceable tip, mounted on the hollow elongated member, to fill with fluid when the rod is moved in a first direction and discharges the fluid when the rod is moved in the opposite direction. A first spring surrounds the rod and exerts a force between a stop, mounted at an intermediate position within the tube, and the rod to bias the rod in the first direction. A second spring surrounds the rod and is interposed between the stop and the inner end of the hollow elongated member. A first limiting member is mounted on the rod to compress the second spring when the rod is moved in the opposite direction beyond a predetermined limit.

Abstract: A plurality of series connected main spark gaps are connected in shunt circuit relation with a voltage grading impedance network which includes a trigger gap that is connected though frequency responsive coupling means in shunt relation with approximately one-half of the series connected main spark gaps. The trigger gap is operative, as a substantially linear function of a voltage impressed across the series connected gaps, to cause the main gaps to spark over in cascade fashion. The triggered control network allows use of a large number of main gaps but with a controlled total sparkover very much less than the sum of the sparkover of the individual main gaps, thus, providing a desirably high ratio of reseal voltage to sparkover voltage for the main gap series circuit.

Abstract: An improved valve prosthesis for causing nontraumatic unidirectional flow of a pulsatory fluid, such as blood, through a conduit, such as a blood vessel. The valve includes two flaps, made of a suitable flexible material, attached by the proximal ends to opposite sides of a covered annular mounting structure. A pair of magnetic members are connected to the distal ends of the flaps thereby to exert sufficient attractive force to hold the flaps together in a closed position to prevent fluid flow through the valve. The magnetically-closed flaps are forced to an open position by the pressure of the fluid flowing through the conduit. A decrease in fluid pressure in combination with the attractive force exerted by the magnetic members permits the smooth, nontraumatic closure of the valve flaps.
