Patent number: 4898108Abstract: A seed singulator for an agricultural planter uses a housing with a seed cavity to which seed and compressed air is delivered and a disc with seed pockets which, in rotating, pick up seed kernels from the seed cavity and drop them at equally spaced intervals. A wear ring prevents the rotating disc from wearing the singulator housing and a resilient air cutoff pad has radial extensions which extend between sealing surfaces on the housing and the wear ring whereby seeds are prevented from wedging between the air cutoff pad and the side walls of the groove in which the pad is installed. The trailing edge of the air cutoff pad has coplanar segments in angular relation to one another which serve to accurately space the seed when using a seed disc with multiple annular rows of seed pockets.Type: GrantFiled: October 13, 1988Date of Patent: February 6, 1990Assignee: Deutz-Allis CorporationInventor: William C.

Patent number: 4851331Abstract: A probe polynucleotide binds to a target nucleotide sequence in the nucleic acid of a biological sample, and then is enzymatically extended in the 3'-direction with a mixture of nucleoside triphosphates including at least one nucleoside triphosphate that has been detectably labeled. After separating extended hybrid from unreacted nucleoside triphosphates, detectably-modified nucleotides which have been incorporated are determined. In some forms, the 3'-terminal nucleotide of the probe polynucleotide is selected to form a matched pair with some sample strands, but a mismatched pair with other sample strands. In such cases, if the primer dependent enzyme used for extension is one lacking 3'-exonuclease activity, then only those hybrids forming such a matched pair will be extended and subsequently determined.Type: GrantFiled: May 16, 1986Date of Patent: July 25, 1989Assignee: Allied CorporationInventors: Calvin P.

Patent number: 4824769Abstract: A positive photoresist metal ion aqueous developer is provided that gives a high contrast to the photoresist.The developer disclosed comprises a formulation of aqueous alkali-base such as potassium hydroxide and a carboxylated surfactant. The incorporation of the carboxylated surfactant provides the unexpected increase in the contrast of the photoresist. The addition of the carboxylated surfactant increases the gamma from a typical photoresist gamma (.gamma.) of 3 or less to a gamma greater than 5.The high contrast photoresist provides linewidth control and affords improved process latitude in photoresist imaging. The linewidth control is particularly critical in cases where fine lines are to be defined in the resist that covers steps of topography on the coated substrate. The higher the contrast, the less affected the resist by the topography, provided the exposure is adequate to expose the resist.Type: GrantFiled: April 28, 1987Date of Patent: April 25, 1989Assignee: Allied CorporationInventors: James M.
