摘要:
A fastener for fastening a component having a mounting hole has an essentially U-shaped clamping region that at least partially grips around the component and has two opposing legs that are connected together as a single piece by a connecting region. The legs are provided with through holes that serve to accommodate a pin or stud that passes through the mounting hole of the component. A nut is attached to a first leg on the side facing away from the second leg such that the connection between the first leg and the nut can be released by a separating force acting on the nut.

The invention relates to a clutch device with a pressure piston (1) for generating a pressure force for moving a clutch (4, 9, 8, 10, 27), in which the pressure piston (1) is guided to slide in a housing (5, 15.1) and the housing (5, 15.1) and the pressure piston (1) enclose a pressure chamber (11), which can be pressurized with a pressurizing agent (24) to generate the aforementioned pressure force and in which a balance piston (2) is present to generate a counterpressure force on the pressure piston (1), which is held essentially immobile to the housing (5, 15) when the clutch (4, 9, 8, 10, 27) is put into motion in the sliding direction of the pressure piston (1) and which, together with the housing (5, 15.1) and the pressure piston (1), encloses a balance chamber (12), which can be pressurized with a counterpressurizing agent to generate a counterpressure force. A latching mechanism (28.1, 29.1, 30.1, 31.1) is provided according to invention hold the balance piston (2) immobile as described above.

The invention concerns an intermediate layer (2) for enhancing comfort of a user wearing usual objects on or in the body. The intermediate layer comprises at least an element consisting of a heat-sensitive gel having a lower critical solution temperature (LCST). Under the influence of the user's body or skin temperature (T), the intermediate layer actively produces a constant modification of the contact point(s) between the usual object and the user's body (3).

A charging arrangement for a baking oven (8) is provided with a supply arrangement (9) for dough pieces (4) and a lifting and delivery device (34) for the dough pieces (4). The supply arrangement (9) is provided with a charging inlet, at least one supply bin (10, 23) and a supply outlet arranged underneath the charging inlet. A delivery inlet portion (37) of the lifting and delivery device (34) that is located at the bottom is in delivery engagement with the outlet of the supply arrangement under the influence of gravity. A baking system (1) with such a charging arrangement (9) can be easily operated and does not require the continuous presence of an operator. Furthermore, it can have an optically attractive design.

摘要:
An oscilloscope includes at least one demonstration signal generator integrated as part of the oscilloscope. The demonstration signal generator generates stimulus signals that consist of digital samples of various different stored waveforms without the need of a separate demonstration board or signal source. The demonstration signal generator may loop through different sections of the stored waveforms to generate respective stimulus signals that include sequences of digital samples from the different waveforms in combination, to provide a broad range of stimulus signals. The stimulus signals may be displayed on the oscilloscope or output from the oscilloscope as demonstration mode stimulus signals to demonstrate the capabilities of the oscilloscope to customers or for training.
