    摘要： The invention relates to an apparatus for drawing off ground air under the foundation slab of a house. A tube is placed in an excavation made some meters away from the house. The bottom end part of the tube is downwardly open and is provided with a plurality of rows of holes through which a blower, arranged inside the pipe, draws air from the ground. The ground air which is withdrawn departs via an evacuation duct opening out above the ground surface. A lid is arranged airtight at the upper end of the tube. The evacuation duct connects up with the tube in an area above the blower.

    摘要： A reject chamber for use with a hydrocyclone for separating a fiber suspension into a heavy fraction substantially containing heavy contaminants and a light fiber fraction substantially containing fibers, the reject chamber having an internal cavity, a reject inlet into the internal cavity, and a reject outlet out of the internal cavity, the longitudinal axis of the reject outlet being angled relative to the longitudinal axis of the reject inlet. The reject chamber has a stem that extends into the internal cavity at the elbow of the reject chamber, and at least two bumps, each of which extend into the chamber on opposite sides of the stem, the reject chamber taken along a cross section through the stem and between the bumps having symmetrical sides.

    摘要： A device for continuous and individual feeding of sheets from a stack to a depositon site comprises gripping members (15) for grasping and hoding the sheets, and a movement device for displacing the gripping members (15) between the stack and the deposition site. The movement device displays two arms (12, 13), which are provided with the gripping members (15). The arms (12, 13) are pivotal about a vertical pivot axis (14) and are movable therealong in the verical direction to positions (33) for both depositing and picking a sheet. Further, the one arm (12, 13) may be pivoted past the other (12, 13). A feeder station for feeding in accordance with the foregoing includes at least one sheet stack, a deposition site and a feeder device. The stack and the deposition site are disposed on a common arc of a circle, and the feeder device has a pivotal arm (12, 13) which is provided with gripping members (15). A method of feeding in accordance with the foregoing in which use is made of a movement device as disclosed above. One gripping member (15) discharges a sheet when the second gripping member grasps a sheet on the stack. Thereafter, the gripping members (15) are lifted and pivoted so that they pass each other, whereupon they are both lowered, so that the method may be repeated.

    摘要： A receiver having a digital automatic gain control (AGC) circuit is disclosed for use in a cellular communication system, including a Hierarchical Cellular System. The receiver includes a controller which switches between gain control values depending on system operational mode. In this way, the AGC can be optimized for different types of receive processing operations, e.g., traffic reception and measurement of other channels.

    摘要： A .SIGMA..DELTA. modulator-controlled, phase-locked-loop circuit, and an associated method, generates a frequency-regulated signal which does not exhibit undesired tones. Dithering signals are generated and are provided to a .SIGMA..DELTA. modulator. The .SIGMA..DELTA. modulator forms a division-factor control signal used to control the division factor of a frequency divider forming a portion of the PLL circuit. The dithering signals applied to the .SIGMA..DELTA. modulator reduce the likelihood that the .SIGMA..DELTA. modulator shall enter a limit cycle and generate repetitive output signals.
