Abstract: EARTHQUAKE SIMULATOR            Abstract An earthquake simulating machine has a vibrating plat-form mounted in a  frame.  The platform is driven by a hy-draulic piston which reciprocates the platform through a lever system having a mechanical advantage of about ten to one.          The vibration of the platform is isolated from the frame by shock absorbing bushings which support the lever system.          Shock absorbing feet may be used to support the frame.  The hydraulic piston is controlled by a hydraulic circuit and by an electrical circuit which provides the input to the hydraulic circuit.  A feedback circuit  monitors the output vibration of the platform

Title: Measuring device for a frequency analysis of signal  levels over a wide range of frequencies
Inventor: SCHWIERZ THEODOR
IPC: H04B3/48
Filed: 1978-12-27
Granted: 1982-05-04
Abstract: ABSTRACT The invention relates to a measuring device for a frequency anal-ysis of signal levels within a large frequency range, which is extremely fast. To this end, the measuring device comprises an intermediate-frequency amplifying arrangement having two or more selective amplifiers, each equipped with automatic amplifying control.  The wide-band control loop of each ampli-fier contains essentially a controllable attenuator and a regulating ampli-fier.  The band-width of the selective amplifiers, which are connected in series, is reduced in stages in the direction of the signal flow. The con-trol factors from the regulating amplifiers are added together in an adder and are fed to a signal-level-evaluating and indicating device.

Abstract: Abstract of the Disclosure The idle and main fuel passages of a carburetor are controlled by metering apparatus which is regulated to maintain the idle and part throttle air-fuel mixtures at a selected air-fuel ratio, but during low temperature engine operating conditions the part throttle mixture is leaner than the idle mixture in any particular regulated mode of the metering apparatus.  This invention provides a mixture forming assembly which further includes means for leaning the idle mixture only during such low tempera-ture operating conditions; the metering apparatus is then regulated to a rich mode at idle during low temperature engine operating conditions to provide an idle mixture which is leaned to the selected air-fuel ratio, and a lean part throttle mixture is avoided as the throttle is opened from idle to a part throttle position.

Abstract: Abstract of the Disclosure:          Method and apparatus for treating fibrous plant material, preferably straw, with aqueous alkali solution, preferably soda lye. The straw is supplied at the bottom of a container filled with aqueous alkali solution which is characterized in that it has no uniform alkali concen-tration but an alkali gradient such that the alkali con-centration is highest at the bottom of the container and lowest at the top thereof. While rising upwardly in the container by its own buoyancy, the straw is thus treated with aqueous alkali solution of successively decreasing concentration. Finally, the straw is removed from the top of the container and flushed. In the flushing operation only so much fresh flushing water is supplied as corresponds to the liquid absorbed by the straw. As a result, a closed system in respect of the treating liquid will be obtained. The container has supply means for supplying plant mate-rial and lye of high concentration at the bottom and a grid, conveying means and flushing means for the plant material at the top. Besides, the container has at least one levelling vessel between the top and the bottom for adjusting the liquid level in the container upwardly and downwardly by supply and withdrawal, respectively, of liquid and resultant control of the level of the straw column in the container.
