Abstract: A package wrapping machine includes a wrapping station where film is to be manipulated during a packaging operation. A support is provided for holding rolled film, the support located to permit film to be drawn into the wrapping station. A sensor arrangement detects package size data that is used to set one or more wrap parameters.

Abstract: An engine system having a low EMI/RFI signature. The system comprises a two-stroke engine having a cylinder with a piston sized for reciprocal motion through the cylinder. The two-stroke engine further includes an injector deployed in communication with the combustion chamber to discharge a fuel into the combustion chamber. An electronic control unit controls the injection and ignition for the engine, and an EMI/RFI reduction system is utilized to lower the electromagnetic and radio frequency interference signature of the engine.

Abstract: A fuel injected, internal combustion engine that is protected from detrimental ignition due to pocket sparking. The engine includes one or more cylinders into which fuel is injected by an injector. A spark plug is used to ignite the fuel-air mixture within the cylinder. The spark plug is designed with a base and a shell extending from the base to define a hollow interior. A central electrode is disposed in an insulative core and extends through the hollow interior of the shell. The shell is connected to a secondary electrode. A gap is formed between the electrodes for promulgation of a spark to ignite the fuel-air mixture. The detrimental effects of pocket sparking are eliminated by placing a closure member between a terminal end of the shell and the nose of the insulative core. This closure member may be in the form of a lip that extends from the shell into proximity with the nose of the insulative core.
