Title: Antisense gene systems of pollination control for hybrid seed production
Inventor: FABIJANSKI STEVEN F
IPC: C07K14/415
Filed: 1989-02-02
Abstract: A process is described for producing hybrid seed using male-sterile plants created by employing molecular techniques to manipulate antisense DNA and other genes that are capable of controlling the production of fertile pollen in plants. Transformation techniques are used to introduce constructs containing antisense DNA and other genes into plants. Said plants are functionally male-sterile and are useful for the production of hybrid seed by the crossing of said male-sterile plants with pollen from male-fertile plants. Hybrid seed production is simplified and improved by this invention and can be extended to plant crop species for which commercially acceptable hybrid seed production methods are not currently available.

Title: Water delivery manifold assembled from a series of interlocking valved units
Inventor: MILLER LEONARD L
IPC: F24D3/10
Filed: 1989-07-10
Abstract: A fluid delivery manifold (10) especially designed for water systems in buildings and residences is the subject of this invention. The manifold is formed from a plurality of identically configured fittings (12) provided with male and female ends (16 & 18) so that like fittings may be frictionally joined without the need for thermal welding. Retaining rods (60) extend the length of a gang of joined fittings (12) and are designed to provide compressive forces to maintain the fittings in sealing relationship. The fittings (12) are joined together in pairs which make an integral unit so that side-by-side hot and cold water manifolds may be presented in one assembly operation. The juncture between the integral pair of fittings is, however, designed to present a line of weakness (X) so that the two fittings may be separated if desired. Each fitting has three equal flat elongated surfaces which are disposed at 90 DEG relative to each other so that fittings may be joined in three different rotational positions.
