A closed system for harvesting fat through liposuction, concentrating the aspirate so obtained, and then re-injecting the concentrated fat into a patient comprises as its main components a low pressure cannula having between about 7 to 12 side holes of about 1-2 mm by 2.0 to 4.0 mm, a spring loaded syringe holder with a helicoidal spring to apply a substantially constant pressure over the full excursion of the plunger, and a preferably flexible collection bag which is also preferably graduated, cylindrical over most of its body and funnel shaped at its bottom, all of which are connected through flexible tubings to a multi-port valve. The multi-port valve has two flutter/duck bill valves which restrict the fluid flow to a one way direction which effectively allows the syringe to be used to pump fat out of a patient and into a collection bag in a continuous manner. After the bags are centrifuged to concentrate the fat, the excess fluids are separated and the valve is re-connected to permit the syringe pump to reverse fluid flow to graft the concentrated fat back into the patient.

The present invention relates to a route planning method oriented to goods delivery. A method of grouping firstly and then arranging a route is adopted, and a large-scale logistics delivery vehicle path problem is divided into multiple small-scale logistics delivery vehicle path problems, so that a calculation amount can be greatly reduced, and a solution speed is improved. Moreover, for a constraint to a load weight of a freight vehicle, relatively high uniformity of the number of delivery points in each delivery region obtained by division is ensured by adding a limitation to a capacity constraint for each cluster set in a clustering method, so that a total weight of goods in the delivery region obtained by division will not exceed a maximum load weight of the freight vehicle, and region division becomes more reasonable; and furthermore, by integrally considering an optimization principle of a freight vehicle route and a regional principle of a delivery point geographical location, a same freight vehicle is arranged for the delivery points of which the geographical locations are close to each other, and therefore, the delivery efficiency is improved.

By arranging the refiner memorizer between the liquid lift tube and the casting mold gate, and utilizing the melt and flow of metal liquid, the refiner is carried into the casing mold, and meanwhile, the melt temperature while being carried into the casting mold is reasonably lowered so as to achieve the purposes of grain refining and shrinking looseness reduction.

A multi-phase pulse generator provides an even number of pulse signals of same phase difference and pulse signals of higher frequency by applying a negative delay concept. The multi-phase pulse generator includes a first delay block with first unit blocks which have a first negative delay property respectively and of which an even number is ring-coupled; and a second delay block including second unit blocks which have a second negative delay property respectively and of which even number is ring-coupled. The number of the first unit block and the number of the second unit block are the same. A plurality of output nodes is formed based on one-to-one sharing between the first unit block and the second unit block having output signals of different level. Each output node outputs a pulse generated by racing the output signals of different level to each other which are provided from the first unit block and the second unit block connected to the each output node.

Stators for an electrical machine which are fitted with a polyphase winding which is in the form of a plug-type winding and the winding sections of which run through slots of the stator and comprise a plurality of different conductor elements are already known. At least some of the said conductor elements have in each case two conductor limbs and in each case one connecting conductor which connects the two conductor limbs, wherein an even number of n conductor limbs is arranged one above the other in the radial direction with respect to a stator axis in each slot. Each conductor limb of one of the conductor elements is provided in its slot in a specific position with respect to a slot base of the slot. These polyphase windings comprise a comparatively large number of different conductor elements, in particular so-called special conductors which differ from the standard conductor elements. These special conductors increase the manufacturing costs. In the case of the stator according to the invention, a few different conductor elements are provided for the polyphase winding. According to the invention, it is provided that the lower conductor elements (5) each have conductor limbs (5.1) which are situated in the same position and the upper conductor elements (6) each have conductor limbs (6.1) which are situated in the same position, wherein the step width of the lower conductor elements (5) in relation to the step width of the upper conductor elements (6) differs by the value of one, in particular is greater by the value of one.
