摘要:
The electrical unit has a printed circuit board (10) supporting the circuit, which includes a power component (11) which generates heat. In order to dissipate this heat from the power component, the power component rests on a heat conductive layer (13) which in turn is applied to the upper side (12) of the printed circuit board. This heat conductive layer further has a portion of the lid (18, 19) of the housing resting on it, which serves as a cooling area. Alternatively, the cooling area can be a free-standing cooling element. The heat transfer thus takes place via the heat conductive layer (13) to the cooling element (18, 19) so that the latter may be applied and formed independently of type and form of the power component.

Oven and method for operating an oven, comprising an On/Off-key (4), at least one key (3, 5) for choosing a predefined oven function or for choosing a predefined oven program and/or for programming a not predefined oven program, at least one specific key (6), which enables the user to start a preferred oven function or a preferred oven program from an Off-mode or a Standby-mode of the oven, wherein a running oven function or a running oven program can be saved by a memory unit as a preferred oven function or as a preferred oven program, when the specific key (6) is actuated at least for a predetermined period of time.
摘要:
The laminations of a stack that form an iron core for a magneto armature are provided with wart-like deformations produced by through-stamping, so that pressing the stack together will provide a press-fit at the locations of the deformations. The core is mounted by screws through mounting holes respectively in the yoke and at the end of one leg of an E-shaped core, while the press-fits produced by superposed deformations hold the rest of the core together against warping and twisting. Protuberances from the annular cup casing, which contains the winding mounted on the middle leg of the core, grasp the lamination stack in a region remote from the mounting holes to prevent the press-fit locking of the laminations from loosening.

摘要:
A therapeutic air mattress for attending patients consists of an inflatable hollow body provided with a pair of symmetrically arranged longitudinal air tubes which form an inflatable single chamber system and which almost adjoin one another in a head region and are spaced from one another in a body region where an intermediate chamber is provided in which an oblong resiliently deformable body is displaceably arranged, having a lower degree of deformation that the inflated pair of air tubes. Alternatively, the intermediate chamber also is inflatable, but independently of the pair of tubes, and in use is blown up to a greater extent than the pair of tubes.Patients lying on the mattress can be set in rhythmical vibrations in order to attend on articular rheumatism and blockages of vertebrae and articulations.
