This invention relates to a novel dwarf Brassica oleracea plant and a useful variety of rapid-cycling B. oleracea containing the single recessive mutant gene for the dwarf phenotype homozygously. The single gene (dwfl) is produced by mutagenesis and selection and is useful for producing novel types and varieties of dwarf Brassica plants for ornamental or agricultural purposes.

A garment incorporates a detachable garment strip. The garment has a first series of releasable fasteners attached to a garment part, and a second series of releasable fasteners attached to the garment part and spaced apart from the first series of releasable fasteners. The detachable garment strip is designed to overlie the garment part between the first and second series of releasable fasteners. The garment strip has first and second strip edges, a third series of releasable fasteners attached along the first strip edge, and a fourth series of releasable fasteners attached along the second strip edge.

A valve to shaft assembly includes a butterfly-type valve, a pair of bushings receiving the valve and holding the valve in axial position within a housing, and a shaft engaging the valve and the bushings and rotating the bushings in the housing. The bushings include features to hold the valve in position in the bore prior to assembly of the valve and, furthermore, act as rotating bearing surfaces for the valve. The valve to shaft assembly process may be simplified, especially where multiple valves are assembled to a single common drive shaft, such as in a port face charge motion control valve. Furthermore, the valve to shaft assembly provides an axial degree of freedom between valve, drive shaft, and bore, which allows the valve to float on the axis of the drive shaft, to facilitate self centering of the valve in the valve housing.
摘要:
A vane-type throttle valve assembly including a body having a passage therethrough and a pivotable shaft transverse of the passage and supporting a vane for variably restricting the flow of material through the passage. The shaft is disposed in opposing bores in the valve body. Each bore includes an access slot. The valve is assembled by inserting an integrated shaft and vane into the passage, engaging the ends of the shaft into the access slots, and translating the shaft ends in the access slots until the ends of the shaft are positioned in the bores. The shaft is retained in the bores by bushings inserted from outside the valve body. In a currently preferred embodiment, the access slots are formed over an angle from an axis of the bores, and the shaft ends are entered into the bores by rotating the shaft and vane about the passage axis.

An adjustable shoe to properly fit a wear's heel, midfoot, forefoot and toes. The lower edges of first and second body members are securely attached to the first and second side edges, respectively, of a sole member from a point conterminous with the midline of the toe end of the sole member to points on the first and second side edges, respectively, of the sole member spaced from the midline of the heel end of the sole. A first attachment structure adjustably secures the heel end portions of the body members relative to one another. A second attachment structure adjustably secures the forefoot portions of the body members relative to one another.
摘要:
An educational kit for the classroom study of plants including a compact plant growth environment and a seed of fast-cycling Brassica plants. The fast-cycling plants grow in compact areas and have generation cycle times of sixty days or less making them convenient for classroom study. Various experiments on plant growth, physiology and genetics can be performed with the kits.
