The invention relates to a method for the riveted fastening of an accessory to a plastics fuel tank (11, 12), the riveted fastening taking place at the time of the production of the tank by extrusion blow-moulding of a split tubular preform or two web-like extruded preforms made of thermoplastic material by using a multi-part die after or during the moulding of two complementary shells. The accessory (4) has been provided or is provided with at least one opening. The method according to the invention is characterized in that the riveted fastening takes place by means of at least one prefabricated rivet pin (9) made of thermoplastic material. The rivet pin has been obtained in a separate production process, for example by injection-moulding.

The invention relates to a device for superimposing an image in the beam path of an aiming optics, having an at least partially transparent optical support element which is arranged in the beam path of the aiming optics and has at least one diffractive optical coupling element and at least one diffractive optical decoupling element, the at least one diffractive optical coupling element leading light of the image to be superimposed, which light is incident on said coupling element and is to be coupled in, through the optical support element to the at least one diffractive optical decoupling element for the purpose of superimposition with the beam path. The image to be superimposed is imaged into the beam path of the aiming optics by the at least one diffractive optical coupling element and the least one diffractive optical decoupling element.

Semiconductor layer material, e.g., for use as an emitter material for a heterojunction solar cell, is formed as a stack made of multiple first layers and second layers alternatingly situated one on top of the other. The first layers is made of an elementary, polycrystalline semiconductor, and the second layer is made of a substoichiometric electrically insulating compound, e.g., an oxide, carbide, or nitride, of the semiconductor. The interfaces between the first layers and the second layers are irregularly structured by a temperature treatment in such a way that microcontact areas are formed between adjacent first layers, which are separated from one another by a second layer.

A method and arrangement reduce an interference which is caused in a received signal from a reception antenna by a transmitted signal with transmitted data which are distributed stochastically over time from a transmission antenna which is physically close by. The transmission of the transmitted signal from the transmission antenna is activated and deactivated by a control signal from a control circuit over time such that reception dropouts in the received signal which are caused by the interference are corrected by an error correction unit for the received signal.

A purge drain valve including a spool spliced in a fluid line includes a control valve and an actuator coupled to the control valve for regulating fluid flow. During a washing operation, fluid flows between a supply end and a delivery end of the spool, and during a purging operation, the control valve diverts fluid entering the supply end from the delivery end towards a drain leg. A washing system includes a fluid supply coupled to an input of a wash delivery system and a delivery line coupled to an output of the wash delivery system. The purge drain may be spliced into the delivery line to permit fluid to reach a wash apparatus during a washing operation and to prevent fluid from reaching the wash apparatus during a purging operation. A rinse cycle sensor apparatus may be employed to indicate to an operator if a washing operation is complete based upon a conductivity of fluid exiting from a device being washed.

The invention relates to a pair of hand-operated pliers (1), in particular pressing pliers, with jaws (6, 7) and hand levers (4, 5), wherein the jaws (6, 7) are pivotable around a preferably common rotational axis (x). Furthermore, one hand lever (5) is connected by a joint to one of the jaws (7), and a pressure support is located between the hand levers (4, 5) for the formation of a toggle (K). In order to further improve a tool of this type, particularly with respect to the design of the pressure support, it is proposed that the pressure support consist of a support roller (18) arranged on one hand lever (4), and of a curved section (19) which is attached to the other hand lever (5) and which works together with the support roller (18).
