Title: Method for the determination of the hybrid purity of tomatoes
Inventor: VODENICHAROVA MARGARITA S
IPC: A01H1/04
Filed: 1992-04-06
Abstract: The method serves for hybrid identification of tomatoes and may be applied in seed production, selection and selection-genetical research of tomatoes. It accelerates the process of hybrid identification and enhances its accuracy. The method consists in electrophoretic decomposition of the alcohol dehydrogenase and/or esterase in a parental form seed extract and F1-hybrid tomatoes and depending on the phenotypic forms of certain iso-enzymic strips-markers of enzymes, the mother, father and hybrid type spectrums are identified. On the basis of this, the purity and the degree of hybridity of the tomato seeds are determined.

Abstract: Abstract of the Disclosure METHOD FOR FORMATION OF AN ISOLATING OXIDE LAYER          In a method for the formation of an isolating oxide layer on a silicon substrate, an anti-nitridation layer is formed on a silicon substrate at locations where isolating oxide is desired.  The anti-nitridation layer has openings therethrough which expose the silicon substrate at locations where isolating oxide is not desired.  A thin silicon nitride layer is selectively grown at the locations where isolating oxide is not desired by nitridation of the exposed silicon substrate.  Isolating oxide is then selectively grown at the locations where isolating oxide is desired.  The thin silicon nitride layer inhibits oxide growth at the locations where isolating oxide is not desired. The method reduces "bird's beak" formation and is particularly applicable to high density IGFET devices.                             - i -

Title: Tape Measure End Hook
Inventor: KNAPP RALPH E
IPC: G01B3/10
Filed: 1990-06-13
Abstract: A floating end hook for a measuring tape is disclosed which defines two openings for receipt of first and second rivets for attachment of the end hook to the measuring tape. The openings lie on an axis parallel to an inside surface of an abutting member of the end hook.

Abstract: ABSTRACT OF THE DISCLOSURE.      A low differential pressure rotary syphon for the purpose of removing condensate from the interior of steam a  heated  dryer  drum  under  low differential  pressure conditions.  The reduction in the magnitude of differential pressure required to remove the condensate is accomplished through the direct introduction of steam into a central plenum area receiving condensate thereby reducing the mass density of the condensate mixture.  The reduction in mass density and the steam introduced acting directly on the condensate within the central plenum area facilitates the removal of the condensate from the drying drum interior.
