Patent number: 7140456Abstract: A cutting auger has a main auger blade and a front subsidiary coaxial blade each having a drive core and a helical auger flight carried on the drive core for rotation about a longitudinal axis of the drive core with a cutting edge at an axial end face of the auger flight, such that when rotated the cutting edge cuts a hole equal in diameter to the helical flight and the helical flight carries the cut material away from the cutting edge. The second auger blade having a smaller diameter than the first, is shorter than the first and is arranged with the helical turns thereof in opposed angular direction. A planetary drive system is arranged to rotate the first and second cutting augers in opposed direction with the first driven at a slower angular velocity than the second so as to balance the torque.Type: GrantFiled: March 26, 2004Date of Patent: November 28, 2006Inventor: Brian Maki

Patent number: 6796922Abstract: A planetary gear 5 is contacted at its at least one tooth of all its teeth 51n with an end edge 23d facing an inner releasing part 23c of an inner peripheral surface of a receiving hole 23a irrespective of a rotational position of the planetary gear 5. By doing so, the planetary gear 5 is prevented from moving in the radial direction. As a result, the planetary gear 5 can be prevented from vibrating in the radial direction. Thus, vibrations of a planetary gear apparatus can be reduced, and the planetary gear and a carrier can be reduced in damage.Type: GrantFiled: March 12, 2003Date of Patent: September 28, 2004Assignee: Bosch Automotive Systems Corp.Inventors: Shinichiro Nakajima, Makoto Nishiji

Patent number: 6164812Abstract: The electric food processor has a housing in which there is disposed an electric motor with a motor shaft. The motor shaft, via a gear mechanism, drives three or more concentric output drives at different rotational speeds. The common axis of rotation of the output drives is spaced a distance from the motor shaft. Working tools are selectively coupled to the output drives and the working tools rotate in a working container which is placed on the housing. In order to expand the possible uses of the food processor, the fastest output drive rotates at a speed that is suitable for a mixing tool, and the gear mechanism has at least two sets of input gear teeth that are rotatably mounted independently of each other, so that the fastest output drive can be driven out of direct engagement with the slower output drives.Type: GrantFiled: May 26, 1998Date of Patent: December 26, 2000Assignee: BSH Bosch und Siemens Hausgeraete GmbHInventors: Peter Brezovnik, Aleksander Oblak, Helmut Augustin

Patent number: 6122984Abstract: A phase control mechanism controls phase relationship between two shafts. The phase control mechanism may be used to control various mechanical devices such as the pitch of propellers of aircraft and boats, the pitch of power producing windmills, opening and closing lathe and drill chucks and controlling the eccentricity of some forms of continuously variable transmissions when the mechanisms are not only stationary but also in normal operational motion.
