Abstract: A plum tree generally similar to the Simka variety of plum tree (U.S. Plant Pat. No. 1,882) but distinguished by bearing fruit which ripens about ten days earlier and which has a 90 to 100 percent red-purple skin coloration.

Abstract: A strawberry variety characterized by large plants bearing late-ripening, large fruit.

Abstract: A pittosporum plant which has a dwarf habit of growth and having leaf blades which are variegated, there being irregularly shaped areas of three different colors present on the variegated leaves, such being dark green, medium green and pale yellow. The variegated leaves do not have a uniform pattern of variegation, and the pattern of variegation differs from leaf to leaf.

Abstract: The rate of flow of a fluid through plastic tubing is varied by clamping a portion of a circumferential section of the tube wall with sufficient force to fully close that part of the passage between the clamped wall portions, permitting fluid flow only through the resulting, remaining open cross-sectional area. Cold flow of the plastic material of the clamped portion of the tubing wall, such as might otherwise effect a change in the remaining cross-sectional flow area, is prevented or minimized by rigidly confining the clamped section. To adjustably vary the flow rate, the operative, passage-defining wall section of the tubing is varied by uniformly varying the ratio of the section of clamped tubing, and the remaining, operative wall portion of the tubing, or by deforming the operative wall portion.

Abstract: A signal indicating that the correct exposure value has been achieved and a signal indicating the completion of flash are logically summed to provide a shutter closing signal. This ensures that the shutter will be closed even when the light emitted by the flash is insufficient to achieve the proper level of exposure.
