  • Patent number: 4781276
    Abstract: A hydraulically actuated wheel brake with a built-in control device comprising a brake piston including two pressure surfaces each of which defines a different one of two working chambers. The pressure fluid inlet is connected directly to one of the two working chambers and via a valve to the other of the two working chambers, the valve being actuatable upon attainment of a predetermined value of inlet pressure. The brake piston has a step in its outer periphery whose surface provides one of the two pressure surfaces. The piston is guided exclusively at its outer periphery in a cylindrical bore of a housing. Since only two parts are disposed concentrically in each other, there results ease of manufacture and a minor susceptibility to failure.

  • Patent number: 4715486
    Abstract: A frictionally engaging device, such as a disc brake, includes a first and a second friction element which engage one another as the device is operated to reduce the extent of and/or eliminate relative movement between these elements. The first element consists of an organically bonded friction material suffering relatively more pronounced wear, and the second element is made of a metallic material, especially iron, which suffers lesser wear in operation. The extent of wear of the first element is reduced by applying a coating of a particulate material, especially such deposited by high kinetic energy impacting of the particles, on the frictional surface of the second element which cooperates with the first element. The coating advantageously contains metals, such as cobalt, chromium and/or nickel, and/or metal carbides, especially those of tungsten and chromium.

  • Patent number: 4675987
    Abstract: A relay is sealed with a sealing compound when the relay housing is in a closed state, thus causing an air cushion to be formed in the inside, with an afterflow of sealing compound into the interior being prevented. Following gelling or curing of the sealing compound, a vent hole is pierced into the relay housing which, if required, may be closed following degassing of the interior space of the relay.

  • Patent number: 4677441
    Abstract: A two-way ranging system in which deviations of transmit times of interrogation signals from a nominal transit time are determined at a transponder. These deviations are dependent upon the propagation conditions for interrogation and reply signals in the medium of propagation. A normally fixed delay is developed in the transponder. This fixed delay occurs between the reception of an interrogation signal and the transmission of a reply signal. This fixed delay is so shortened as to compensate for transit time deviations of the interrogation and reply signals.

  • Patent number: 4672216
    Abstract: A power station boiler condensate water monitor employs a light-scatter cell for the detection of oil and/or particulates in the water. In order to determine background scatter levels, provision is made to alternatively pass clean water through the cell (FLUSH). The offset voltages obtained from the detector outputs when clean water is employed are compensated for differences in temperature between the boiler condensate water and the clean water before substraction from the detector outputs when boiler condensate water is employed. The monitor is capable of detecting oil levels of less than 2 parts per million.

  • Patent number: 4672387
    Abstract: An antenna system which has omnidirectional coverage in azimuth and sectoral coverage in elevation. A main reflector including a reflecting surface has polar symmetry about the Z-axis. It also has a cross section in any plane containing the Z-axis which satisfies the laws of power conservation and reflection. It is determined by the desired far-field pattern and the microwave feed pattern (for example TM.sub.01) employed. Single or dual reflector systems are described. Using the system on "receive" with multiple "feeds", full azimuthal direction finding of incident radiation can be achieved.

  • Patent number: 4668914
    Abstract: A magnetic field sensor is disclosed with which the direction of a magnetic field can be determined by using the planar Hall effect. An active layer of the sensor is made of a ferromagnetic amorphous metal which is magnetically isotropic. Thus, the magnetization in the active layer always has the direction of an external magnetic field. The developed planar Hall voltage is a measure of the direction of the magnetic field.

  • Patent number: 4665347
    Abstract: In picture-reproducing equipment with higher scanning frequencies (e.g., flicker-free television, visual display unit), the generation of the horizontal-deflection current is separated in frequency from the generation of the operating voltages by supplying the horizontal-deflection circuit from a DC voltage source which is part of the voltage power supply providing the operating voltages. The supply circuit is preferably connected to the grounded deflection capacitor. This makes it possible to influence the picture geometry in a simple manner, particularly to perform horizontal pincushion correction.

  • Patent number: 4660972
    Abstract: The spatial position of the core of an optical waveguide (1) can be observed exactly in that the optical waveguide is irradiated, in two mutually perpendicular directions, with parallel light, which thereafter passes through each time one rod lens (31, 32) and into a deflecting optical system (8, 9, 10). With the aid of this deflecting optical system it is possible to produce two side-by-side images of the optical waveguide and its core. With the aid of such an arrangement the cores of two optical waveguides to be joined, can be optically aligned with respect to each other in a simple way.

  • Patent number: 4661136
    Abstract: For fabricating porous bodies from a glass starting material, particularly in connection with the fabrication of an optical waveguide preform, it is proposed to fill powdery glass starting material under a pre-compaction into a compression mold, and to compress it thereafter. When the porous body to be formed is to have a varying composition in the radial direction, as is necessary with a view to step index optical fibers or optical waveguides having a graded index of the refractive-index profile, then differently composed powdery glass starting materials are filled one at a time, in adjacent coaxial areas, into the compression mold. This is effected with respect to each of the individual areas with the aid of a screw conveyor under a continuous, adjustable pressure and at an adjustable conveying speed.
