Abstract: The mass spectrometer has multiple collectors for measuring the intensity of ion beams and a resolving plate having a plurality of aperture clusters. The plate is rotated to selectively position one of the aperture clusters between the beams and the collectors. The apertures in each cluster have separations which allow beams of predetermined ion mass to impinge upon the collectors.

Abstract: A new and distinct variety of orchid. More particularly a quadrigeneric orchid hybrid known as Yamadara Midnight Magenta `Fine Wine` hybrid which is outstanding and distinct from other orchids because of its superior flowers which combine rare coloring, outstanding shape, number of flowers on the stem and excellent plant vigor. The coloring is rich dark burgundy wine throughout all parts of the flower. The new cultivar is also distinctive from its sibling population and similar hybrids by its outstanding plant vigor and reliability of bloom. Its flowers are of exceptional substance with thick and more resiliant petals than related siblings of the grex. They are perfectly placed on the stem; the stem is superior to its relatives in strength; the flowers have a longer bloom life and are produced more abundantly than orchids of the nearest similar breeding.

Abstract: A new and distinct variety of orchid, more particularly a Laeliocatonia hybrid plant having flowers of unique and spectacular coloring with heads of flowers erectly carried on strong sprays. The new variety is distinct from syblings of its grex by its outstanding vigorous plant structure as well as extreme freedom and frequency of bloom. A primary note with this cultivar is its compactness of growth and dramatic distinction from syblings of the grex as well as superiority over others of the type.

Abstract: A new and distinct variety of orchid and more particularly a Brasso-laeliocattleya (Blc.) hybrid plant which is outstanding and distinct from other orchids because of its superior flowers, which combine a rare coloring, massive size, and strong carriage of flowers on a single stem. The coloring is an exceptionally warm dark rose-purple with a brilliant darker labellum shaded and veined yellow in the throat. The new variety is also distinctive from its siblings in the grex population and similar hybrids by its outstanding plant vigor. The flowers are of exceptional substance with thicker and more rigid petals than siblings of the grex. They are perfectly placed on the stem, with stem superior to its relatives in strength. The flowers have a longer bloom life and are produced more abundantly than orchids of similar breeding.
