Abstract: 2.1 The purpose of obtaining automatic switching of the differential locks in the drive train of vehicles is served by measuring instruments with which the steering angle of the steered front wheels is determined. With cross-country vehicles, there are problems in mounting the devices for determining the steering angle directly on the front axle. 2.2 In order to achieve reliable measurement of the steering angle irrespective of the use to which the vehicle is put, it is provided for a transmitter wheel (15) which is provided with a tooth system (27) to be mounted directly on the steering column (10), which transmitter wheel is operationally connected to sensors (16, 17) whose signal is fed, in common with that of a switch (28) for the purpose of determining the central steering position, to an electronic evaluating system (25) by means of which shift elements for actuating the differential lock can be influenced with the aid of an output signal (24). 2.3. The method and device represent a determination of the steering angle for actuating differential locks which is suitable for vehicles with hydrostatic steering units and does not require increased additional outlay on construction. <IMAGE>

Abstract: A method of extracting roasted and ground coffee is disclosed. Extraction water is fed to one end of an extraction vessel containing roasted and ground coffee, and coffee extract is withdrawn from the other end. Flow of water to and extract from the vessel is intermittently halted, and extracted roasted and ground coffee is intermittently discharged from the vessel, while a portion of unextracted coffee is charged to the vessel at the other end. The movement of coffee in the extraction vessel is countercurrent relative to the flow of the extraction water. The method of the present invention is less complex, is more easily controlled, requires a lower capital investment and produces a more aromatic coffee extract of better flavor balance.

Abstract: An imaging lidar system is presented which employs a multipulse multiple gating system which is particularly well suited for underwater imaging. The imaging lidar system utilizes a multipulse Q-switched laser operating within the pumping envelope of discharging flash lamps (or other means) to cumulatively illuminate a single frame on a camera (e.g., CCD camera) while the camera is gated repetitively so that each pulse is "observed" at the same depth; that is, the gated camera views that same illuminated area in the ocean. The sequence is repeated at a frequency which is both the laser pulse repetition rate and the camera frame rate. The system also allows the use of multiple cameras with frame addition or with frames processed separately. As a result, energy is extracted from the laser in the form of short (1-10 nsec) pulses by rapidly Q-switching during the time the laser is being pumped by the flashlamps. Provisions are made for subtracting solar noise during daylight, if necessary.

Abstract: In a battery charger, a barging current is supplied to a rechargeable battery and a load current to a load circuit from a DC voltage source during a charging mode and the battery is allowed to supply a load current to the load circuit during a subsequent discharging mode. The battery voltage is compared with a reference voltage for detecting a low voltage condition, whereupon a counter is triggered and a warning signal is generated if the low voltage condition continues for an interval longer than a specified value. According to a second embodiment, the battery voltage is compared with low and high reference voltages and a first comparison signal is generated when it is lower than the former and a second comparison signal is generated when it is higher than the latter. The high reference voltage is set equal to a value which is lower than a voltage to which the battery can be charged during a normal condition, but higher than a maximum voltage to which it can be charged during an abnormal condition. A warning signal is generated if the first comparison signal is not followed by the second comparison signal.

Abstract: A controller for reducing unwanted sideways motion of an aircraft by reducing lateral side loads, resulting from air mass, turbulence and gusts. The controller functions in a manner that in the presence of higher frequency side loads, the rudder is caused to move in a relieving direction so that the net force across the vertical stabilizer is zero. A pressure differential across opposite sides of the vertical stabilizer is measured and used to generate a first rudder deflection signal. To maintain stability of the aircraft, a beta-dot signal from the yaw damper module is gain adjusted and filtered to generate a second rudder deflection signal which is added to the first rudder deflection signal. The resulting combined signal reduces lateral side loads at higher frequencies without comprising aircraft directional stability.

Abstract: A process for the long term modification and regulation of lipid metabolism -- generally to reduce obesity, insulin resistance, and hyperinsulinemia or hyperglycemia, or both (these are the hallmarks of noninsulin dependent, or Type II diabetes) -- by administratlon (i.e., by feed or injection into the bloodstream) to a vertebrate, animal or human, of a dopamine agonist, e.g., bromocriptine. Administration of the bromocriptine is made over a limited period at a time of day dependent on the normal circadian rhythm of fat and lean members of a similar species. Decreases in body fat deposits result by treatment of an obese species on a daily timed sequence based on circadian rhythms of the peak prolactin, or peak prolactin and peak glucocorticosteroid, blood level established for lean members of a similar species. Insulin resistance, and hyperinsulinemia and hyperglycemia, or both, can also be controlled in humans on a long term basis by treatment corresponding to that of the treatment for obesity. The short term daily injections reset hormonal timing in the neural centers of the brain to produce long term effects.
