    摘要: A circuit having a load connected to ground, a measuring resistor connected in series with the load; a current source feeding current into the load and the resistor, a different amplifier having one output connected to one end of the resistor and having its output connected to a summing point which is an input from the current source, a reference voltage source having one end connected to the summing point, is improved by an impedance converter having its input circuit connected to another end of the resistor and its output connected to another input for the differential amplifier, the latter output being further connected to an opposite end of the reference voltage source thus serving as floating ground for the reference source and the differential amplifier.

    摘要: The photometer is calibrated by using a permanently built-in installation of four, similarly configured chambers in a good heat conducting carrier which is slidably interposed between sample and reference chambers on one hand and the detection structure on the other hand. One pair of these chambers is placed in the paths during measurement and is filled with inert gas, the other pair has one chamber filled with calibration gas, the other one with inert gas. All chambers are closed with similar windows.

    摘要: A monitoring system for several process control stations includes a redundancy station having a central processing unit and an operating memory to take over the functions of a dropped out process control station. The takeover involves internal bus separation to separate auxiliary and long term storage facilities from immediate processing facilities in each of the process control stations so that upon separation of the latter from the former the redundancy station can effectively take over together with the peripheral equipment and auxiliary devices. The redundancy station cyclically monitors the operating state of the several process control stations and particularly tests status information contained in the particular buffer portion of each of the processing stations. Moreover, relevant data is copied into a standby buffer during each cyclic monitoring step to be used if, pursuant to the next reoccurring supervising and monitoring step, the particular process control station is found to be defective.

    摘要: An optical information-bearing signal is regenerated by branching a portion off that signal while the remaining portion permanently bypasses the regeneration. The branched-off portion is converted into an electrical signal which is processed to regenerate, at a higher power level, the information in a manner which is dynamically invariant to a wide range of input level changes. The regenerated signal is superimposed upon the passed-through signal. A three-signal level encoding scheme is employed and the regeneration involves referencing the branched-off portion electrically against two thresholds in a manner which maintains a constant amplitude relation between the thresholds and the arithmetic average of the electrical signal representing the branched-off portion. The regenerating units are used in series and designed so that two or more in a row can drop out and still the signal can be regenerated by the next operational regeneration.

    摘要: A cylindrical vessel is provided with inlet and outlet tubes extending axis parallel, excentrically and diametrically opposed into the vessel from the top. The tubes have radial apertures and are closed on the bottom. A gamma ray detector sits also on the bottom. Blowing directly against the wall of the vessel is avoided and the resulting flow pattern is vortex-free and laminar to avoid stagnation zones.

    摘要: An electric household blender which effectively disables a person from placing his hand in the container while the blades are still rotating. The electric blender includes a container holder 2 and a motor base 4 having associated guide surfaces, a lock ring 9 rotatably mounted within said motor base, and lock bolts 8 arranged on the lock ring so as to protrude through openings 13 in the motor base housing. The lock bolts cooperate with pins 7 arranged on the container holder so as to align the lock bars with lock bolt supports 12 arranged in the container holder. The blender further includes a lock bar 11 which has a stud on one end and which defines a recess 29. The stud is adapted to cooperate with the lock ring for the rotation thereof, and the recess is adapted to selectively block or allow movement of a lock rod 26 equipped with a shoulder, which prevents rotation of said electric operating switch when the above locking elements are in their unlocked positions.
