Abstract: A mouse trap having a flexible handle made of a thin strip of plastic material and normally extending in upright relation from one end of the trap so as not to impede access to the trigger of the trap by a mouse nor movement of the trapping bail between its latched and sprung positions. The handle is sufficiently flexible to permit handling and transport of the trap by grasping an upper end of the handle with the base and trapped mouse suspended in depending relation from the lower end of the handle. The handle also is bendable into closely overlapping relation to the top side of the trap to permit compact containment of the trap in conventional packaging.

Abstract: A pneumatic system which in the preferred embodiment includes a pump having a primary suction port and a secondary suction port, with the pump being operable for generating vacuum pressures at both such ports. A first vacuum operated system is coupled to the primary suction port and a second vacuum operated system is coupled to the secondary suction port, and a predetermined, preferably selectively adjustable, orifice is established between the first and second vacuum operated systems for enabling vacuum airflow generated at the first suction port to augment the airflow through the second vacuum operated system. In an alternative embodiment, separate standard vacuum pumps are coupled to the first and second vacuum operated systems.

Abstract: A pneumatic control system for machinery and the like which have a plurality of intermittently operated pneumatic use points or work stations. The system includes a common pneumatic source of sufficient capacity to maintain a predetermined minimum pressure level during the operating sequence of the system, a line connecting each use point to the common source, and a non-pressure responsive, selectively adjustable, throttling valve interposed in each connecting line for establishing a desired pressure at the use point relative to the pressure of the common source. The system is controlled such that the use points draw upon the common source in a predetermined sequence and rate such that the total capacity demand on the common source remains substantially constant, and thus the use point pressures remain constant without the need for relatively expensive pressure regulator valves in the respective use point connecting lines.
