The device is especially useful in measuring static charge generated by the rapid discharge of a pressurized container.

Abstract: A baler for forming round roll bales of agricultural products includes a baling chamber in which a plurality of bale-forming rotatable rolls form a bale which is wrapped with a binding tape supplied into the baling chamber from the tape supply roll positioned outside and above the baling chamber. The baling chamber is formed by two portions of the housing which are hinged away from each other to discharge the formed and wrapped bale from the baling chamber. A pair of tape advancing rollers receive a starting end of the tape from the supply roll and advance it into a gap between two adjacent bale-forming rolls so that the binding tape is taken along by the rotating formed bale in the baling chamber. A counter of the number of revolutions of at least one of the advancing rollers is provided, which causes cutting off a tape portion from the binding tape by a control device after the number of revolutions of the advancing roller has reached an adjusted number.

Abstract: The invention relates to a pair of shears for shearing sheet metal. Known shears, for example power shears, require relatively great forces, which cannot be produced except by special gear means. For rendering it possible to manually shear even relatively thick sheets, according to the invention it is proposed that the movable blade (22) of the shears is connected to a drive mechanism (13,15,17) and is located above the stationary blade (6) of the shears in its starting position for shearing, and that the drive mechanism is supported in the stand (1) of the shears for vertical movement, whereby the dead load of the drive mechanism and of the movable blade is utilized by gravity action for the shearing work.

Abstract: Apparatus for cutting straps wound on a bale of material in which the bale of material is brought into contact with a cutter blade which is forcibly retracted against the action of a spring whereafter the cutter element is released under the pressure of the compressed spring and is thrust forwardly against the bale to cut the straps on the bale.

Abstract: An impact press includes drive means for reciprocating a sleeve at one end of which a ram is slidably and rotatably carried, the same being normally held in a retracted position by retaining means. The drive means that reciprocates the sleeve toward and away from impact tooling also regulates in synchronization therewith a releasing means by which the retaining means lets go of the ram to permit it to fly under the influence of a bias until it impacts the tooling. Reaction from the tooling after the punching has been completed provides a force for receiving the ram in the sleeve. If desired, the driving means can also be used to regulate the operation of a workpiece feeder, a workpiece brake, and any regulator that the impact tooling may have, all in synchronization with the movements of the sleeve. If a conventional air feeder is used, owing to limitations of the feeder, the device can be operated at 180 strokes per minute.
