Abstract: A hair clipper variable comb attachment, for use with a hair clipper having a fixed upper blade and a movable lower blade, including a blade mount, a main part, a comb carrier, and a pair of adjustment pegs. The comb carrier has a front and a plurality of longitudinally extending tines that increase in height as they extend rearwardly. The blade mount secures to the fixed upper blade of the clipper. The comb carrier is slidably attached onto the main part so that as the adjustment pegs are rotated the comb carrier can move forwardly with respect to the blade to increase cutting height of the clipper and can move rearwardly to decrease cutting height. Adjustment of the comb carrier position and thus the cutting height can be made without removing the comb attachment from the hair clipper.

Abstract: ROUND HONEYCOMB ROTOR to improve the performance of conventional propellers being used as rotor for aircraft, motorized pumps, vessels as well as for any use in hydraulic or pneumatic applications. It has helical pieces starting from its cube or circular nucleus and mounted on one or several tubular cylinders which are concentric between them. On the one hand the cylinder with largest diameter will have a conical main piece in order to control and direct centrifugal forces on their way out. On the other hand helical pieces come together shaping helical trapezoids which are fitted one onto the other giving the whole thing a round honeycomb shape. The outer perimeters are totally closed down allowing the combination of all centrifugal forces improving over ten times the performance of conventional propellers in any of the already mentioned applications.

Abstract: Round honeycomb rotor for wind generators and most propellers has bent tubular trapezoids, two or more concentric tubular cylinders and a variable number of round bent tubular trapezoids. Both cylinders and trapezoids form modular trapezoidal tubes, which have large wind contact surfaces. The concentric tubular cylinders of the round panel have bent pieces fitted in between them whose function is to minimise wind exit and multiply wind contact surfaces in wind generators. As for propellers rotors the number of round bent tubular trapezoids gets multiplied as well as its wind contact surfaces, which results in the optimum use of most centrifugal propelling forces thanks to the reduction of wind entrance and the amplification of wind exit.
