Abstract: A passive vibration damper (3a) is described which utilises the hysteresis of an elastic gasket and the energy dispersion produced by the passage of a gas, in this case air, through small-diameter bores; it consists of a cylinder (6) connected to the vehicle body and housing slidably in a fluid-tight manner a piston (12) which divides the cylinder into two variable-volume chambers; there being rigid with the piston a rod (13) connected to the engine, and in the chambers there being housed respective elastomer gaskets (35) which cooperate with the piston; when this latter moves due to relative movement between the engine and vehicle body, it transfers air contained in the diminishing-volume chamber into the increasing-volume chamber through a plurality of axial bores (30) provided in the piston, and squeezes the elastomer element located in the diminishing-volume chamber, so that it progressively closes said bores.

Abstract: An amplifier circuit is placed in the wheel assembly of the landing gear of an aircraft. The amplifier circuit amplifies a signal whose frequency is proportional to the speed of the wheel prior to transmitting the signal over a transmission line to sensing and control circuits. This permits a high frequency signal to be generated at the wheel assembly and insures that the signal has sufficient power to be sensed by a remotely located sensing circuit even though the signal may be attenuated by the capacitance in the transmission line. This permits a higher frequency signal to be generated than previously possible. This provides greater wheel speed resolution and enhanced sensitivity for aircraft landing gear anti-skid systems.

IPC: C23C14/06

Abstract: The mixed crystal layer (C, D) of metaloids on a workpiece, applied by means of reactive physical coating, has an incorporation ratio of metaloids which changes continuously in the thickness direction. The mixed crystal layer (C, D) is present on a separation layer (A) of the workpiece. For the production of the metal layer (C, D), titanium is evaporated in a crucible, which is moved to and fro in front of the workpiece surfaces to be coated, in a vacuum chamber, and two gases which have different affinities to the vaporised titanium are passed in. To produce a first part layer (C) of the mixed crystal layer (C, D), the incorporation ratio of the gases is continuously changed. During coating, the workpieces rotate so that their surface sometimes faces the crucible and sometimes faces away. The coated workpieces are distinguished by high flank wear resistance and crater wear resistance. <IMAGE>

Abstract: The invention relates to a method and a device in connection with radar for measuring the angle position of a target relative to a point of measure. The measuring is carried out by means of a continuously scanning radar operating with monopulse technique. The angle deviation of the tar­get is obtained by comparison of echo signals received on the receiver antenna (3) within a distance interval. The deviation is added (7) to a reference angle position to calculate a reference angle position. A num­ber in the angular direction adjacent reference related angle positions of the target showing a stipulated minimal requirement of the signal energy are weighed together (8, 9).

Abstract: Agricultural spreader, such as for example a field sprayer, with a spreader linkage which extends on both sides of the machine transversely to the direction of travel of the machine and is suspended, oscillating in an upright plane, on the frame of the spreader by means of one or more articulations, the spreader linkage being on one side partially or completely retractable, i.e. one side of the spreader linkage can be retracted independently of the other side. In order further to develop the generic agricultural spreader in such a manner that oscillating movement of the spreader linkage remains guaranteed when spreader arms of the spreader linkage are extended unsymmetrically in relation to one another, it is envisaged that, between the frame of the spreader or the linkage central part (4) arranged movably up and down on the frame on the one hand and the spreader linkage on the other hand, a compensating device (59) is arranged, which compensates unsymmetrical weight ratios and simultaneously allows the oscillation of the linkage and which becomes effective when the spreader linkage is unfolded unsymmetrically. <IMAGE>

Abstract: An improved and optimized design for a universal infusion coffee filter pack designed to fit and provide for consistent brewing of quality coffee in a variety of American style and European style coffeemakers. The infusion coffee pack (34) comprises a first circular piece (40 a ) of filter paper, having its surface area stretched and increased by at least 3% to form a rounded pocket, and sealed to a second circular piece (50 a ) of filter paper to form a substantially one half inch (1.27 cm) sealed flange (32) therearound. A metered quantity of coffee grounds (36) is sealed within the rounded pocket, and is provided with a head space (38) of substantially fifty percent or greater of the volume within the round coffee pocket. The first (40 a ) and second (50 a ) circular pieces of filter paper each preferably have a diameter of approximately five inches (12.7 cm), and are filled with a metered amount of ground coffee to brew five cups of water. In this optimized design, the presence of the one half inch (1.27 cm) flange (32) in combination with the increased surface area caused by stretching results in a brewed coffee having an increase in soluble solids extraction and a decrease in the standard deviation of soluble solids extraction.
