Abstract: This disclosure describes systems, methods, and apparatus for detecting and displaying a number of rounds in a firearm magazine comprising a maximum number of N rounds. The magazine may comprise a follower, magnets on the follower, and <N magnetic switches arranged along a path of the magnets when the follower moves along a length of the magazine, the switches configured to activate based on a magnetic field exceeding a threshold, and a first antenna arranged on an inside of the magazine and parallel to a firing direction of the firearm, and configured to wirelessly transmit a round count indication to a second antenna on the firearm, the round count indication based on the round count data, the second antenna affixed to an inside of a magazine well of the firearm and mostly overlapping with the first antenna.

Abstract: The present disclosure provides a system for tracking usage and provenance information for one or more garments in the from of a set of one or more tags or “logbooks”, each intended to have an associated garment. Each tag is embossed with a set of information to facilitate easy recording and tracking of provenance and usage information related to the associated garment for later reference.

Abstract: In a method for controlling the process parameters of a machine for producing hollow glass articles, the shape of the produced hollow glass article is measured online by means of at least one camera immediately after its shaping. Deviations from a reference shape are detected, and these deviations are used as the basis of the control. The control is a storage medium that contains a mechanical model describing the functional correlation between a certain pattern of a deformation of the hollow glass article and an adjustment of process parameters. An intervention in the adjustments of process parameters is carried out in accordance with the type of deformation detected.

Abstract: The disclosure pertains to an apparatus to shape the interior surface of a pipe made of thermoplastic material, where the apparatus includes a shaping component. the surface of this shaping component can have at least one notch and at least one smooth continuous surface area. The shaping component can have at least partially a cylindrical shape and/or at least partially a conical shape. The notch or notches can run spirally or closed and can either extend over the entire length of the shaping component or can only be located along a specific length of the shaping component. The notch or notches can be connected to a pressure system to produce vacuum and/or positive pressure in the notch. This can facilitate enhanced feeding and gliding of the interior surface of the pipe at the shaping component. The disclosure also pertains to a system to manufacture pipes made of thermoplastic material, where the system includes an above apparatus to shape the interior surface of a pipe made of thermoplastic material.

Abstract: The present disclosure relates to a corrugated pipe made of thermoplastic plastic, which includes an inner pipe and a corrugated outer pipe connected thereto, wherein the profile of the outer pipe includes first sections with a first average diameter, second sections with a second average diameter greater than the first average diameter, and, disposed therebetween, flanks that connect the first sections to the respective adjacent second sections. The geometric relationships of the corrugated pipe are designed to yield not only high rigidity against pressure forces acting on the corrugated pipe in the radial direction and high flexibility with regard to bending of the corrugated pipe transversely to its longitudinal axis, but also, at the same time, a low weight in comparison to conventional corrugated pipes. This reduces the consumption of plastic during production and makes the corrugated pipe easier to handle when it is being laid.
