DETAILED DESCRIPTION OF THE PREFERRED MODALITIES According to a preferred embodiment of the present invention, the food preparation apparatus, for example that shown in Figures 1 and 2, consists of a blender or blender 10 having a container or vessel 12, a transmission 14 which can be attached or coupled and which has an outer housing 15 and an electric motor (not shown). The vessel 12 is coupled to the transmission housing 15 by the connecting ring 16 formed in the housing 15, which further includes an arrow seal 18 and which can also use other seals to form a liquid barrier, when the vessel 12 is attached or coupled. When in the assembled form, the mixing blade 20, which is attached to the first arrow 22, is located within the mixing chamber of the vessel 12. Within the housing 15 are contained the transmission components 14 that include a spring from P120V97MX pressure plate 24, a pressure plate 26, a knurled arrow connection 28, a tracking or tracking guide 30, a waveform ramp 32, a second arrow 34, speed reduction gears 36. A second seal arrow 38 once again provides a barrier separating the internal components from the external environment and further provides a support surface for the rotation of the second arrow, when coupled to an electric motor by the motor link 42. As It is shown in Figures 2 and 3, the transmission 14 is comprised of a rotational drive system 25 that produces rotational movement, which is directly linked to the speed of the electric motor. To do this, the mixing blades 20 are directly connected to the motor by a series of intermediate connections. First, the motor connecting ring 42 is integrally connected to the second arrow 34 which, in turn, is connected to the splined arrow connector 28. The drive system is then completed by connecting the pressure plate 26 to the connector 28 and the first arrow 22 which is used to drive the mixing blades 20. To oscillate the mixing blades 20 in a path parallel to the drive system 25, a waveform ramp 32 having a P1203 / 97MX tracing or tracing surface 48, which is coupled with tracking or tracking guide 30. Ramp 32 includes a series of depressions 31 and elevations 33 imparting vertical movement. As the ramp 32 rotates within the transmission 14, the guide 30 follows a tracking path along the surface 48 and, consequently, is raised and lowered along the vertical axis as the ramp 32 rotates. This vertical movement is then transferred to the mixing blades 20 by having the guide 30 pushed on the pressure plate 26. As the pressure plate 26 rises, it elevates the first arrow 22 that it elevates to the mixing blades. 20. As long as the guide 30 maintains contact with the tracking or tracking surface 48, it can be configured in various ways. As shown, a waveform configuration is used. However, two poles or rollers, or other configurations that may be known to those of skill in the field, may also be used. As the pressure plate 26 rises or rises, it compresses the tension spring 24 which is placed between the pressure plate 26 and the housing 15. The compression spring 24 will assist in the downward movement of the pressure plate. and of the blades, when the P1203 / 97MX guide 30 starts its downward descent to a depression 31 in the tracking or tracking surface 48. The compression force of the spring 24 also serves to maintain contact between the guide 30 and the tracking or tracking surface 48 during all the phases of movement between these two components. The ramp 32 is driven by the speed reduction gears 36 which are directly linked to the electric motor, but at a reduced operating speed. The first gear 60 is connected to the second arrow 34 and engages the second gear 62 that rotates around the support arrow 64 located in the housing 15. The gear 62, in turn, drives the ramp 32 coupling a gear ring internal 66 located on the ramp 32. It is important that the mixing blades maintain the ability to oscillate vertically while continuing to rotate. This can be achieved by the use of a splined arrow connector 28 and a pressure plate 26. As shown in Figures 2 and 3, the connector 28 has a corrugated outer surface 29 that is adapted to slide fit and match within a internally corrugated perforation 37 of the pressure plate 26. In this configuration, the mating or matching corrugated surfaces prevent the P1203 / 97MX rotational slip, but at the same time allow vertical sliding. This rotational force can be applied continuously during vertical oscillation. As it is also necessary that the guide 30 rotate, as shown in Figure 2, a retainer extension 70 extends from the housing 15 towards the security guide 30. The guide 30 and the extension 70 must be connected by configuring the components to employ a tongue and a groove or some other grooved arrangement that can allow vertical sliding and prevent rotational movement. Of course, these members can be assured in other ways that can be appreciated by those with expertise in this field. However, by making the housing act as a stop preventing the rotation of the guide 30, the rotation of the pressure plate 26 will still be allowed, as already described. Figures 4 and 5 show another embodiment of the invention that does not require the use of a spring. In this embodiment, which is configured in a manner similar to that already described above, the guide 80 includes two downwardly extending posts 82, which are connected to the waveform ramp 84, by the use of portions that are extend inwardly 86, which extend into the slot 88 of the waveform ramp 84. In operation, the extensions 86 travel in the slot 84 P1203 / 97MX during the rotation of the ramp 84. This causes the guide 80 to be either pulled down or lifted upwards, thus causing the mixing blade to oscillate vertically. Figure 6 shows an alternative embodiment of the invention, wherein the guide is the rotational element and the waveform ramp remains stationary. In this embodiment, the waveform ramp 90 replaces the use of the guide and is incorporated within the device, as indicated above in relation to the guide 30. In this mode, the guide 92 is the one connected to the medium. Drive and rotate. The vertical oscillation is then provided through the use of the waveform configuration in the guide 90. These two elements can be interconnected as already described before in any of the modalities, using the use of a spring or the modality that employs a tongue and groove arrangement, as shown in Figures 4 and 5. While preferred embodiments of the present invention have been illustrated and described, it will be understood by those of ordinary skill in the art that other changes and modifications may be made. without thereby departing from the invention in its broadest aspect. Therefore, it is intended that these changes and modifications be covered by the following claims. P1203 / 97MX
