Abstract: A method of making a metal can end with a tear-open plastics closure, for a can intended to be resistant to leakage when subject to internal pressures, such as arise from carbonation of a beverage or thermal processing, wherein the undersurface of the can end is provided with a plastics coating (14). and the can end is pierced to form an aperture (15) with a peripheral downturned flange (16) at an angle of 80° to 120° to the plane of the can end and having a flat end. A one-piece ring pull closure is injection moulded on to the can end (10) from a plastics material resistant to softening at up to at least 65°C, without additional heating of the metal, so as to fill the aperture (15), bond with the coating (14), and enclose the flange (16), with a residual thickness below the flange of 0.08 to 0.5 mm. The thickness of the plastics material of the closure is such that it can be sheared against the flange when the ring pull (26) is pulled manually. The residual thickness of the plastics material may be varied around the aperture to increase resistance of the closure to creep, and the aperture may be pear-shaped or may be circular with a separate vent hole.

Abstract: In a processing machine which operates with an arc, for example, a burning cutting installation, the arc current is measured and regulating signals are derived from the measurement value for the purposes of regulating the tool-workpiece spacing. In that procedure the analog measurement value is converted by a converter into high frequency signals whose frequency corresponds to the respective measurement value, the high frequency signals are fed to a regulator and therein are converted again into analog and/or digital signals. Also provided is a capacitive or inductive spacing measuring means which is also connected to the converter so that the arc current measurement values and the spacing values of the capacitive or inductive measuring arrangement are processed by the same converter means and evaluation circuit.

Abstract: In the method, a sensor scans the ground surface and generates corresponding signals which are evaluated in an evaluation circuit and used to determine the working depth, there being determined from the signals a value which takes account of the clods lying on the ground surface, is characteristic of the ground profile, and corresponds to a value which would be obtained by scanning an ideally levelled ground surface, and the working depth being determined as a function of this characteristic value, the characteristic value being determined on the basis of the signals of the sensor that are detected in a specific interval of time or travel, and the characteristic value being determined by summing up and subsequent averaging of the signals detected in intervals. In order to develop a method or an apparatus of the type mentioned at the beginning in such a way that the seed corns are always deposited at the correct depth in the ground even under the most difficult conditions, it is provided that for the purpose of determining the characteristic value the extremely raised or large clods and the extremely deep gaps between the individual clods are not taken into account, or are filtered out, during averaging. <IMAGE>
