Abstract: A kalanchoe plant named Dignity, characterized by its excellent keeping quality, free branching and vigorous growth habits, well clustered, pink flowers, high floriferousness, and its adaptability to various pot sizes and to growth regulators.

Abstract: A hybrid Kalanchoe cultivar named Fortyniner having deep yellow flower color, strong compact growth, floriferous and uniform flowering habit, excellent keeping qualities, and an adaptability with the use of growth regulators to commercial production in 9 to 15 cm. containers.

Abstract: A new and distinctive rose of the Floribunda Class is provided which resulted as a sport of the Meigandor variety (U.S. Plant Pat. No. 4,520). The new variety forms highly attractive double blossoms which differ in coloration from those of the parent variety. More specifically, the buds of the new variety are of a deep orange-gold coloration and the flowers are of a medium yellow coloration. Additionally, the buds of the new variety are more tapered in contrast to the more squared bud shape of the parent, and the stems tend to be of a larger caliper and of a greater length than those of the parent. The new variety is well adapted to forcing in greenhouses to yield an abundance of well-formed long lasting blossoms.

Abstract: An intraocular lens includes a body lens and a plurality of lens-centering filaments extending outwardly in a common plane from spaced rim portions of the lens body. The lens is particularly adapted for implantation in the eye posterior chamber after extracapsular cataract extraction. When the filament ends are inserted into the cleft of the capsule, the resilience of the filaments centers the lens behind the pupil. An annular lip having at least one opening projects from the rear face of the lens body and seats against the posterior capsule. A discission can be easily performed without dislodging the lens by inserting the discission instrument through the opening in the lip and into the space behind the lens. The lip also limits the progress of vitreous humor toward the anterior chamber after a discission, and may limit lens fiber growth on the posterior capsule within the lip region. In an optional embodiment, fluid flow channels are provided through the lens to prevent pupillary block.

Abstract: A quill drive comprising a housing adapted for mounting on machine tools. A quill is slidably mounted in a longitudinal bore in the housing, and is longitudinally positioned by a ball screw. The ball screw is driven for longitudinal positioning of the quill by a variable speed, reversible motor. The quill rotatably supports a spindle for driving various cutting tools. The spindle is advanced longitudinally by the quill and is rotatably driven by a second motor. The quill drive can be used singly or in a multiple arrangement on transfer machines or other automatic equipment. The unique design has fewer parts resulting in a simple reliable, relatively inexpensive device which is compact and easy to use. A relatively simple modification of the gear box converts the quill drive into a drive for tapping threaded holes.
