International Classification:

G06F 9/44

US Classification:

717105

Abstract:

A pattern implementation technique in which a pattern is defined as a software artifact that comprises a pattern signature representing one or more parameters of the pattern and a pattern implementation model representing one or more methods for expanding the pattern in a selected software context by assigning one or more arguments to the one or more parameters. The pattern implementation model can be based on one or more framework code sets, each of which supports the creation of plural patterns by providing a pattern implementation model for a particular software context. The framework code sets can be rendered extensible by a pattern author by virtue of providing methods whose code is adapted to be modified by a pattern author when defining a pattern. The pattern can be applied by creating an instance of the pattern in a software context and presenting a graphical representation of the pattern instance that can be manipulated by the pattern user in order to apply arguments to the pattern parameters.

Appl. No.:

David Stevenson - Canton NY, US

International Classification:

E03F 5/22
F16L 11/00

Abstract:

An intake nozzle fits onto the suction hose of a vacuum pumper truck. The nozzle comprises a tubular housing and the rotor within the housing near the intake end. The rotor includes a hollow cylindrical canister and spiral vanes on its exterior. Ambient air enters an air tube, penetrates the side of the housing and supplies ambient air to the interior of the canister. The air exits through outlet ports into the liquid waste as it moves past under vacuum. The injected air reduces the density of the liquid waste, speeding up the pumping process and reducing the incidence of blockages.
