Abstract: A process gas for use in laser welding with a laser beam focused onto the work piece to be welded. The inventive process gas comprises helium, nitrogen, and at least one of carbon dioxide in an amount of up to 40% by volume, and oxygen in an amount of up to 30% by volume. The gas may comprise not more than 85% by volume of helium. Also disclosed are methods of laser welding using the inventive process gas. The invention is suitable for laser welding of low-alloy steels and coated, especially zinc-coated steels.

Abstract: The invention describes process gas mixtures for laser beam welding that contain at least one noble gas component. Pursuant to the invention the process gas mixture contains between 50 vpm and 15.0% by volume hydrogen. The process gas can preferably contain one or more of the noble gas components helium, argon and neon. Moreover, the process gas can contain nitrogen. The process gas mixtures can be used in a method for laser beam welding, especially for welding high-grade steels, wherein a focused laser beam is directed at the workpiece surface that is to be machined. Special benefits are associated with ternary or quaternary process gas mixtures with helium and/or neon, hydrogen and nitrogen (for austenitic steels) and helium and/or neon, hydrogen and argon (for titanium or titanium-stabilized steels).

Abstract: An insulation displacement contact, for example for terminal strips, which has a slotted, sprung contact region as a contact-making slot on a connecting bracket, which contact region is surrounded and reinforced by an outer spring slip. The invention provides that the spring clip is designed to form an insulation displacement blade in at least one end region.

Abstract: An insulation-displacement terminal contact, for example for modular terminals, which has slotted, sprung contact region as a contact-making slot on a connecting bracket, which contact region is surrounded and reinforced by an outer spring clip, and which insulation-displacement terminal contact has cutting blades in the inlet region. The invention provides for the cutting blades to project toward one another behind their inlet region. A connecting terminal has an insulation-displacement terminal contact, which has a slotted, sprung contact region.

Abstract: An insulation-displacement terminal contact (1), for example for modular terminals, which has a slotted, sprung contact region as a contact-making slot (3) on a connecting bracket (2), which contact region is surrounded and reinforced by an outer spring clip (4), and which insulation-displacement terminal contact (1) has cutting blades (6) in the inlet region (5). The invention provides for the cutting blades (6) to project toward one another behind their inlet region (5).

Abstract: Serial line connector which has first connectors 1 for a series of lines, including, for example, at least one for signal transmitters and one for a power network. The first connectors 1 are coupled with second connectors 3, by an intermediary circuit board 4. The second connectors 3 could be, for example, signal receivers. Other connectors are structured to form cross-connectors 10 to other serial line connectors. These cross-connectors are arranged as bus bars fixed in an assembly rail. These connectors are connected by leads 16 with those first connectors 1 that are not coupled to the second connectors 3. The serial line connector is suitable as an initiator terminal.

Abstract: A partitioned switching panel of the type including a power switch provided with first switch contacts and mounted on a carriage which is movable toward and away from cooperating stationary second switch contacts disposed behind a partition of the switching panel and accessible via openings in the partition, displaceable shutters mounted on the partition for closing the openings, and an opening mechanism for the shutters which is actuated by the carriage drive for opening the shutters before the incoming movement of the carriage from the circuit breaking position to the operating position begins. The carriage drive is provided with an output lever which is rotatably mounted on the carriage and which is provided with a cam follower which, upon eneragization of the carriage drive to move the carriage to the operating position, traverses a path section in a substantially linear camming track which is fixed in the switching panel, with this path section being ineffective to cause forward movement of the carriage.
