Abstract: A gearshifting arrangement for actuating motor vehicle multi-speed transmissions wherein an electromotive actuation takes place, it being essential that only one electric motor (1) connected with only one cam transmission (4) and only one gearshifting element are provided for actuating all gearshifting sets. The gearshifting element is a connecting rod (5) capable of moving parallel to the axis of the transmission wheels and in which are provided individually actuatable coupling mechanisms (11) respectively associated with a gearshifting lever. The electric motor (1), the spatial cam transmission (4) and the connecting rod (5) are coaxially arranged whereby a very simple and space-saving embodiment is achieved.

Abstract: The 3-D Model Maker of the present invention is a device that builds three dimensional models of computer generated (e.g., CAD) structures by vector plotting layer-upon-layer applications of solidifiable substances. The layers are formed by expelling minuscule beads of the substances in liquid or flowable phase onto a platform from one or more jets, the jets and platform being relatively movable in X, Y and Z coordinate system. The beads are deposited along vectors, during X/Y relative movement, on the stage, one at a time, layer-upon-layer, to build the model. The jets and platform are moved relatively to one another in accordance with instructions from the computer (controller) to form each layer in the X-Y plane (in a manner analogous to an X-Y vector plotter) and either the stage or the jets may move in the Z direction to allow the jets to form subsequent layers.

Abstract: In a motor vehicle transmission, in particular a multi-speed synchronized countershaft transmission, each two speeds are associated with one among several gearshift sets (28, 29). It is essential that the two speeds (1st and 3rd or 2nd and 4th) associated with each gearshift set are not successive speeds. The great advantage here is that the gearshifting thus obtained is a "shifting-shifting" system which makes it possible to carry out overlapping actuating operations and thus a reduction of the time interval between gearshifts. At certain speeds, several gearshift sets or synchronizing mechanisms can be simultaneously loaded whereby the load of the individual gearshift sets (28, 29) is substantially reduced. Great advantages such as shorter gearshifting times, longer service life of the synchronizing sets and smaller gearshift sets may thus be obtained.

Abstract: The device represented in its storage position contains essentially a body (11) in synthetic material containing a reservoir (10) containing a medicinal substance (29). The body (11) is fitted with an applicator nozzle (15). The reservoir (10) has the shape of a cylindrical glass jacket (17) closed at one end by a movable sealing plug (18) and at the other end by a mobile piston (19). The mobile piston is linked with a plunger (16) which advantageously is a spring in a synthetic material. A flow rate controlling filter (19) is lodged in the applicator nozzle (15). This device is advantageous because the reservoir can be sterilized with its contents. The filter and the piston along with the plunger guarantee the medicinal substance remains in an aseptic state by preventing contamination via the applicator nozzle.

Abstract: The monochromator has, as a beam-diffracting element, a scanning mirror (3) which is fastened on a vibratory spring, preferably a spring-steel strap (8), clamped on one side. The vibratory spring is oscillated by way of an electromechanical self-energized oscillation circuit, a sensor (11a, 11b) which detects the deflection of the vibratory spring (8) is provided and whose output signal is used as a feedback signal for maintaining the oscillation of the vibratory spring (8). The amplitude of oscillation of the oscillating element can likewise be varied. With such a design it is possible to produce simply and inexpensively a monochromator with which a considerable spectral range can be swept and, in addition, the width and position of said spectral range can be variably adjusted.

Abstract: The object of the present invention is to permeate sample solution uniformly into an absorbent fibrous sheet. The gelation agent soluble in cold water absorbs moisture and forms a gel, thereby forming a gel medium. Microorganisms are thus cultivated. The surface of a waterproof plate 2 is coated with the mixture 3 of the gelation agent soluble in cold water and microorganism culture medium. Further, an absorbent fibrous sheet 4 is laid on the mixture 3. When the sample solution including microorganisms is poured onto the absorbent sheet 4, the solution is dispersed uniformly over the entire of the absorbent fibrous sheet 4 by the phenomenon of capillary attraction resulting from overlapped fibers. Subsequently, the mixture 3 of the gelation agent and culture medium coated on the plate 2 absorbs moisture and forms a gel. The fibers of the absorbent fibrous sheet 4 are buried and adhered into the mixture 3, thereby forming a gel medium for the culture of microorganisms.
