Abstract: The present invention relates to an Oven muffle (1), comprising at least a first metal sheet part (2) and a second metal sheet part (3) wherein the first metal sheet part and the second metal sheet part are arranged in an overlapping manner relative to each other, wherein the second metal sheet part comprises a portion (32) which is formed by a S-like or Z-like displacement of the second metal sheet part, and wherein the first metal sheet part and the second metal sheet part are connected by a welding seam at least in the overlapping region of first metal sheet part and second metal sheet part.

Abstract: A dustproof and waterproof switch, in particular for a seat belt buckle of restraint systems of motor vehicles for indicating that the latch plate has been inserted into the seat belt buckle and properly locked, includes two contact plates, composed of a fixed contact plate and a contact spring plate, wherein the contacting regions of the contact plates are disposed in a housing-interior of the switch housing which is protected from foreign matter, and the switch can be activated by moving a slide in a channel disposed lateral to the housing-interior, whereby the spring contact plate is deflected by way of an actuating bracket which is pivotably mounted in the switch housing at one end and penetrates the side of the housing-interior facing the channel at the other end by means of an angled section.

Abstract: The invention relates to an actuator, which is used in a belt latch mechanism of restraint systems in motor vehicles and which indicates the proper locking of the tongue of the safety belt when the tongue is inserted into the belt latch mechanism. The actuator is provided in the form of a double-contact actuator, whereby the contact steel plates are arranged inside a contact space that is closed at the top, and the contact can be actuated by a slide by moving this slide into a channel situated to the side of the inner space of the housing.

Abstract: A pulsed-flow apparatus for spectrometers and the like has a mixing chamber and two syringes each adapted to contain a different liquid and both connected to the mixing chamber. The plunger of each syringe has an outwardly extending rod provided with a toothed rack. A pair of electric armatures are provided, each reciprocable lengthwise of one of the rods and carrying a pressure spring which moves with the armature and, during each move of the armature towards the syringe, advances the plunger deeper into the syringe by the length of one tooth of the rack, but does not extract it when the armature subsequently moves in the opposite direction.
