An adjusting device for a lumbar support comprises a pair of spaced guide members, an adjusting member coupled to the pair of guide members, and a drive mechanism for effecting an adjustment of the lumbar support. The adjusting member is displaceable along the pair of guide members and configured such that the lumbar support is adjusted when the adjusting member is displaced. The drive mechanism comprises a motor, which is provided on the adjusting member so as to be displaceable along the guide members jointly with the adjusting member. The motor may be coupled to a shaft having a structured exterior surface, the drive mechanism being configured to effect a relative displacement between the adjusting member and the shaft.

The invention relates to a method for producing a fiber composite component, comprising the steps: introduction of a first body (12), consisting of fibers and a matrix material, into a mold (10), said first body (12) having a continuous first body edge (18); the first body (12) is irradiated with microwaves (28) to produce a fiber-composite component. According to the invention, the first body (12) is introduced into the mold (10) in such a way that at least parts of the first body edge (18) are brought into contact with the mold (10).

The present invention relates to an object-based processor architecture which allows exact pointer identification by strictly separating pointers and data from one another in the memory and in the processor registers. The access to the memory is performed exclusively via pointers which refer to objects. An object contains separate areas for pointers and data and an attribute field for describing the length of the two areas. Both the pointers in the pointer registers and also the pointers in the pointer areas of the objects directly contain the address of the objects to which they refer. The suggested processor architecture allows the integration of automatic garbage collection, which may be implemented completely or partially in hardware. A real-time capable garbage collection may be implemented especially efficiently through hardware support.

An autoclave for pressure and temperature treatment of objects includes a pressure container having a pressure resistant wall which encloses a pressure chamber for receiving the objects to be treated, the pressure chamber having a free inner diameter of at least 1.5 m; and a heat source for heating the objects received in the pressure chamber, the heat source including a plurality of microwave sources irradiating microwave radiation, which are arranged outside the pressure container. The microwave sources are distributed over the pressure resistant wall at an areal density of at least 4 microwave sources per square meter surface area of the pressure resistant wall; and the microwave radiation irradiated by the microwave sources is coupled through the pressure resistant wall into the pressure chamber.

The invention relates to an air-cooled frequency converter, especially for construction site equipment, such as internal and external vibrators which are operated at a higher frequency than the existing electricity supply, said frequency converter comprising a housing and preferably being connected to a separation transformer for producing a protective extra-low voltage. Said housing is divided into two sections, that is into a converter receiving element surrounding a plate chamber, and a housing section connected to said receiving element and used as a cooling region, inside which cooling air channels and a fan for conveying the cooling air through the cooling air channels are arranged. The configuration of the housing in the cooling region and optionally the embodiment of a transformer chamber are created by annular profiled elements which are cross-cut as desired, surround each other in an interspaced manner, and are coaxially arranged in relation to each other.

For a digital demodulator for AM demodulation of a difference sound signal in a digital multiplex signal, which multiplex signal also comprises a sum sound signal in the baseband position and a pilot carrier at a pilot frequency, and the difference sound signal is modulated on a carrier at twice the pilot frequency, an extremely simple and adjustment-free construction is ensured in that CORDICs (1, 7) are provided which perform a coordinate transformation of polar coordinates into cartesian coordinates and each have a phase input, two amplitude inputs assigned to the coordinates x and y and two outputs assigned to the coordinates x and y, in that a phase-locked loop comprising a first CORDIC (1), a loop filter (2) and an accumulator (4) are provided, which phase-locked loop supplies a phase ramp signal whose repetition frequency is dependent on the input signal of the accumulator, in that the multiplex signal at an amplitude input of the first CORDIC (1), the output signal of the accumulator (4) at the phase input of the first CORDIC (1) and that output of the first CORDIC (1) which is not assigned to the same coordinate as the amplitude input used are applied to the loop filter (4) whose output signal is superimposed by means of a first superposition stage (3) on a frequency selection signal indicating a pilot nominal frequency, and the output signal of the superposition stage (3) is applied to the accumulator input (4), in that a second CORDIC (7) is provided, one amplitude input of which receives the multiplex signal with the suppressed pilot and the phase input of which receives the output signal from a multiplier (5) whose input receives the output signal from the accumulator (4) and multiplies said output signal by a factor of two, and in that the output of the second CORDIC (7) supplies the demodulated difference sound signal.
