Abstract: A method including one or more steps of a procedure for preparing a microscopic sample for a high-pressure freezing process is provided, wherein the sample is provided using an arrangement comprising a middle plate of a high-pressure freezing cartridge and an incubation chamber, wherein the middle plate is attached to a lower surface of a bottom of the incubation chamber by an adhesive and detachable from the incubation chamber by effecting a relative movement between the middle plate and the incubation chamber, wherein the sample is provided on an enclosing element which is fitted into an opening of the middle plate, and wherein, when the sample is to be subjected to the high-pressure freezing process, the relative movement between the middle plate and the incubation chamber is effected, thereby detaching the middle plate with the sample from the incubation chamber. Means to implement the method are also part of the present disclosure.

Abstract: A switch unit, preferably implementing a circuit breaker, includes a contact slide unit formed by a contact slide, a fixed contact piece and a moveable contact piece), and a short-circuit release that acts to displace the moveable contact piece by means of a tappet in the event of a short-circuit. A moveable braking device is configured and arranged such that, following circuit opening displacement of the moveable contact piece in response to a short-circuit, the moveable brake device dampens the return, rebound movement of the moveable contact piece to reclose the circuit.

Abstract: A switching device is disclosed, in particular a circuit breaker, with a thermal release, on which a moving switching piece is arranged by a contact link support. The moving switching piece is borne on a spring body and is arranged opposite stationary switching pieces. A heat-extraction apparatus composed of a heat-dissipating material is in each case arranged at the side, along the stationary switching pieces.

Abstract: A circuit breaker includes a housing equipped with a first switchgear region, in which a quenching chamber device and a sliding contact device having movable contacts are located, the contacts lying opposite fixed contacts, and equipped with a second switchgear region, in which a current release assembly consisting of a short-circuit release and an overload release are located. In an embodiment, a continuous ventilation channel is formed within opposing housing walls along the fixed contacts, the channel acting as a first convective air-flow through the circuit breaker in order to dissipate the heat.

Abstract: Processes and compositions for printing substrates. A printing paste containing a matrix-forming precondensate containing polyorganosiloxanes obtained by a sol-gel process and at least one coloring, luminescent, conductive and/or catalytically active filler is applied imagewise to the substrate and is densified by heat treatment at a temperature below the glass transition temperature of the matrix being formed. The processes and printing pastes are suitable, for example, for the production of conductor tracks and decorative patterns.

Abstract: A device for contacting an electric line includes a contact element, which has at least two contact tongues on the side facing the line. To achieve secure contacting, the contact element includes clamping halves, which are arranged resiliently in relation to one another.

Abstract: To dissipate heat from a lossy electronic component which is fixed to the inner side of a wall of a housing, several of the outer and/or inner sides of the housing are placed into contact with a cooling element. In this way, a large part or all of the housing surface can be used to dissipate lost heat to the surroundings.

Abstract: A control switch with a holder is to be provided which can simply and quickly be secured by one person to a variable-thickness fitting plate. To this end the rose (9) of the control switch has a longitudinal groove (11) and a transverse groove (12). The holder which can be fitted on the rose (9) consists of a lower casing (14), a securing ring (5) and an upper casing (23). The lower casing (14) and the securing ring (5) have matching pitches (20, 6) so that when the securing ring (5) is rotated via a toothed spindle (7) fitted off-center it is axially shifted. After the holder has been fitted on the rose, when the securing ring (5) is rotated, a partial thread (18) fitted thereto is rotated out of the longitudinal groove (11) into the transverse groove (12) and thus pressed by the simultaneous axial movement of the partial thread (18) against the limiting edge of the transverse groove (12) taking the form of a thread segment (13).
