Abstract: The invention relates to a reflective light barrier, with an optical transmitter (3) and an optical receiver (4) positioned on one side of the surveillance area, and a reflector positioned on the other side, which reflector modifies the polarization of the light upon reflection, where at least one optical element (1, 2, 7, 7a, 7b) and one polarizing filter (11, 12) are positioned both between the optical transmitter (3) and the reflector, and between the optical receiver (4) and the reflector, and where the polarization planes (13, 14) of the two polarizing filters (11, 12) intersect each other, such that at least one of the two polarizing filters (11, 12) is extrusion-coated with optically transparent material, either fully and/or on the back, and such that the optically transparent material forms at least one of the optical elements (1, 2, 7, 7a, 7b).

Abstract: The invention relates to an optical arrangement comprising a plurality of transmitter elements and/or receiver elements, a plurality of diffractive and/or refractive optical elements and an optical carrier for the diffractive and/or refractive optical elements, wherein the optical system carrier has diaphragm apertures in whose region the diffractive and/or refractive optical elements are connected to the optical system carrier by means of an injection molding process or of a casting process. The invention furthermore relates to a method of manufacturing such an optical arrangement.

Abstract: An apparatus and method for electro-depositing of a material on at least one side of a metal strip. The apparatus includes at least one casing having a first container section adapted to store under pressure a liquid including the material, a second container adapted to receive a portion of the liquid from the first container section, and a panel. The panel includes an active portion that is electrically polarized at a first polarity, at least one first outlet through which the liquid stored under pressure in the first container section is output in a direction toward the metal strip when the metal strip is conveyed past the panel, and at least one second outlet through which the liquid stored in the second container section is output in a direction toward the conveyed metal strip. The first outlet can be a slit which extends at an angle with respect to the direction in which the strip is conveyed, and the second outlets can be slits which extend traverse to the direction in which the strip is conveyed.

Abstract: Rolling tools are rotatably mounted in rotatably driven rolling heads such that they revolve in a planetary-like fashion while the rolling heads rotate. The rolling tools thus roll with blows or impacts upon the outer surface of the rotating workpiece which is advanced along its lengthwise axis. A diameter reduction of the workpiece occurs and the workpiece material is predominantly displaced in lengthwise direction. The workpiece is moved along its axis in the feed direction at an axial feed velocity of at least 3 millimeters for each workpiece revolution, and in the case of hollow workpieces preferably at least at 5 millimeters per workpiece revolution. Difficulties which otherwise arise for certain materials can thus be avoided, and also the production speed and quality can be increased. For hollow workpieces, undergoing internal profiling upon a mandrel, the workpiece which is advanced at high axial feed is preferably also cold rolled during its return feed or motion.

Abstract: A gearing has on its driving shaft a drive means carrier member carrying drive means in the form of pins protruding towards a driven means carrier member fixed to the driven shaft and carrying divergently arranged driven means. The driven shaft is offset relative to the driving shaft so that the circular orbital path of movement of the driven means surrounds the circular orbital path of movement of the driven means. From the drive means always only one single drive means contacts a driven means and only in a portion of the orbital path thereof which portion is more remote from the axis of the driven shaft than that portion of this orbital path arranged nearer to the driven shaft. In the other portions of their orbital path, the drive means pass within the orbital path of the driven means but do not contact these. This results in an increased torque of the driven shaft.
