Abstract: Apparatus for vertically supporting and guiding a web of plastic film horizontally in applications such as in machines that form the plastic film into bags and fill the bags with bulk material. A longitudinally extending gap is provided between proximate edges of first and second plates. The plastic film web is traversed through the gap. A punch mechanism forms protrusions in the web. The protrusions slide atop the plates and prevent the web from falling through the gap as the web traverses through the gap. The protrusions can, for example, be tab cutouts with terminal ends sliding atop the plates and loops formed between slits extending to a crest.

Abstract: A pressure sensor for an internal combustion engine cylinder. The sensor has a housing with a pair of ends and a bore that extends through the housing. A barrel is mounted in the bore toward one end. The barrel has a cavity. A piezoelectric body is mounted in the cavity. The piezoelectric body has a first and second electrode. The piezoelectric body generates an electrical signal that is indicative of the pressure in the cylinder. A plate is mounted adjacent the barrel. The plate retains the barrel in the housing. An electronic circuit is mounted in the bore toward the other end. The electronic circuit is electrically connected to the electrodes. The electronic circuit receives the electrical signal from the electrodes and provides a conditioned electrical signal as an output.
