  • Patent number: 5828267
    Abstract: In an amplifier which generates an output voltage which is proportional to an input voltage and can be picked off between the outputs of two push-pull output stages and has peak-to-peak values of up to twice the supply voltage of the push-pull output stages, each push-pull output stage is driven by a differential amplifier having a positive and a negative differential input in each instance and whose polarity is so defined that the outputs of the two push-pull output stages have voltages of like polarity when identical voltages are present between the positive and negative differential inputs of the two differential amplifiers, a differential input of one differential amplifier being connected with a differential input of like polarity of the other differential amplifier. The remaining two differential inputs of the differential amplifiers are provided for applying a voltage proportional to the input voltage.

  • Patent number: 5815544
    Abstract: A strainer for filtering a pumped fluid has a strainer body having a wall provided with fluid inlet perforations in an outer surface, a surface cleaning scraper or brush in juxtaposition with the outer surface, and a drive operatively connected to the surface cleaner for moving the surface cleaner over the outer surface for removing accumulated debris. At least one nozzle is oriented towards the cleaned outer surface of the strainer body for directing a jet of liquid against the perforations to assure that the perforations are clear. The strainer is thus self-cleaned continuously without requiring a back wash operation, allowing continuous flow through the strainer.

  • Patent number: 5809156
    Abstract: A sound reproduction device such as a headphone with active noise compensation has a housing and a transducer for converting electrical signals to sound waves is disposed within the housing. The transducer has a diaphragm for separating the volume (V.sub.2) in front of the diaphragm from the volume (V.sub.1) to the rear of the diaphragm. The transducer diaphragm and rear volume (V.sub.1) have a determined compliance. The sound reproduction device includes active noise compensation components for reducing unwanted noise at the output of the transducer. The diaphragm has a compliance (N.sub.M) which is less than the compliance (N.sub.1) of the rear volume (V.sub.1). The diaphragm is preferably constructed from a plurality of layers. In a further preferred arrangement, a damping element is disposed very close to the rear side of the diaphragm. A preferred construction for optimizing the voice coil is described.
