A measuring apparatus to measure adhesive performance of a Pressure Sensitive tape or label, which includes an electric or pneumatic actuator that can be triggered manually or remotely to perform a rolling ball tack evaluation at different or extreme conditions to those standardized in an adhesives laboratory, by using a small laboratory oven or small weathering chamber to simulate those extreme conditions. Also, installing this apparatus inside of those chambers and triggering it remotely through the mentioned actuator installed in the apparatus. The triggering systems includes; a power source to convert the standard laboratory high voltage source to low DC voltage to avoid the risk of an electric shock during the apparatus operation, a couple of metallic isolated cables for electric conduction of voltage to the actuator electric coil, an electric control box containing a momentary push button switch, the actuator containing an electric coil, a spring and a metallic mobile piston, and a mechanical fastening system to attach the actuator to the apparatus and the piston to the mechanical ball release system.

Method for treating outlet air in a pneumatic waste conveying system, in which the outlet air is at least partly the conveying air to be used in waste conveying. In the method in a first phase additional air is brought into the body of conveying air in the partial-vacuum generator of the pneumatic waste conveying system before the output aperture of the partial-vacuum generator, and that in the method in a second phase additional air is brought into the body of outlet air as a consequence of the suction effect brought about by the outlet air in such a way that the outlet air and the additional air mix with each other at least partly. The invention also relates to an apparatus.

The present invention provides a plenum configured to evenly separate and distribute airflow generated by a fan into distribution lines of an agricultural machine. The plenum can utilize angled vanes symmetrically or asymmetrically arranged to form plenum chambers to provide a balanced airflow which contributes to maximizing fan efficiency, including power consumption and performance (airflow and static pressure). Accordingly, the plenum can be configured to separate the airflow and minimize imbalance between the lines during sectional control. The plenum height can be maintained for increased manufacturability and to prevent additional expansion. The plenum length can be configured within allowable space constraints of the machine yet allow airflow to develop upon separation into the lines. Vanes throughout the span of the plenum initially divide the airflow from the fan and maintain separation until the outlets.

The present invention provides an air blaster 100 for removing jammed materials. The air blaster 100 includes a tank 110 filled with compressed air and a dual piston assembly 400 inside the tank 110 for triggering a blast with minimum energy loss and high impact force. The piston assembly 400 includes an inlet piston 320 connected to an outlet piston 250 with a coupling mechanism such that the inlet piston 320 and the outlet piston 250 move in tandem and pressure acting on the inlet piston 320 and outlet piston 250 pushes the assembly 400 towards top of the tank 110 thereby compressing a dampening device/spring 360. The force produced by the instant discharge of air creates a strong blast of air in the tank 110.
