Abstract: A difference between an output current signal (mos) of the mixing circuit (MC) and a current from a controlled current source (CCS) is conducted to an input of an operational amplifier (A). A control voltage (cv) for said current source is a voltage at the output of the operational amplifier (A) being filtered by a low-pass filter, whose limiting frequency equals a low frequency limit of the modulation signal in the received signal (rs). The method is speeded up in that the limiting frequency of the low-pass filter is increased by two to three orders of magnitude at the beginning and is gradually lowered to said value. A rather short time duration of the transient process is achieved so that the working point with a low voltage of the DC component and low-frequency components is set at least five times faster than so far.

Abstract: A method for identifying a protease secretion deficient strain of a microorganism involves producing a mutant of the microorganism, followed by adding the mutant to gel-filled wells of a microtitration plate, incubating the mutant in the gel-filled wells under conditions call sing the mutant to secrete proteins, separating the mutant from the gel, and measuring activity of a secretion protease of the microorganism in the gel, wherein either (i) the gel is a substrate for the secretion protease or (ii) the gel contains a substrate for the secretion protease.

Abstract: A digital strain encoder includes a gage-emitter, a sensor-receiver, a transmitter, and an energy source. The gage-emitter is affixable to a surface to be measured and deformable on a one-to-one basis with the surface, and emits a reference strain signal in the absence of strain and an altered strain signal when the surface is subjected to strain and the gage-emitter is deformed. The gage-emitter also emits a unique reference identification signal. The sensor-receiver floats over the gage-emitter so as not to deform with the surface, and detects the reference and altered strain signals and the identification signal emitted by the gage-emitter. The transmitter is coupled to the sensor-receiver for transmitting the detected reference and altered strain signals to a remote receiver.

Abstract: Caps for bottles with a box of powder material for preparation of beverages. The cap is applied to a basic box with a basic substance enclosed, as e.g. drinking water. The cap contains the other box with the other liquid or powder substance. The box is closed on the bottom-side with aluminum foil and a slant damper and on an upper side by a cover. The damper may be twisted around a hinge and have on an upper surface a one-arm vertical flexible lever arranged above the aluminum foil. The cover has on an internal plane bottom tangs, as well as a barrier, by which during winding up and winding off the cover acts on the lever. By winding off the cover a free end of the lever is elastically bent, creating in it a moment of force, which twists the damper and breaks through and removes the aluminum foil. Upon finishing mixing substances, the blend may be drank through the opening of the box.

During focusing from a point infinitely far to that as proximal as desired, the first lens group is static while the second lens group is moved toward the imaging plane, and the third lens group is moved toward the object.
