Disclosed herein are methods for harvesting adipose tissue so as to preserve an increased population of viable microvascular endothelial cells. Adipose tissue containing microvascular endothelial cells is harvested using a collection apparatus incorporating an elongate cannula having apertures with tissue cutting edges. A sub-ambient pressure is applied to a lumen in the cannula to draw the adipose tissue through the aperture where it is then severed using the cutting edge to disrupt the connective adipose matrix. This harvesting provides a cleaner, more homogeneous sample of adipose tissue, thereby increasing the population of viable microvascular endothelial cells obtained through further processing. Rapid and easy methods for the further homogenization of the harvested adipose tissue are also disclosed.

The invention relates to a method for indirect extrusion casting by utilizing the filling of electromagnetic force and a device thereof. In the method, electromagnetic force is utilized to introduce liquid metal into an extrusion chamber to fill part of a mould cavity by a transmission pipeline; when the liquid metal in the mould cavity reaches a preset quantity, the transmission of the liquid metal is stopped; and an extrusion punching head ascends to push the liquid metal to fill the part which is not full in the mould cavity and continuously ascends to extrude and shape the liquid metal, and the liquid metal in the transmission pipeline flows back to a thermal insulation furnace under the function of reverse electromagnetic force. The invention has simple and convenient method, high automatization degree, good stability and skillful structural design of a special device. The liquid metal is transmitted and filled by a sealed transmission pipeline, and oxidation and air suction are reduced; the flow speed and the flow rate are controllable, and the quantification of extrusion casting is realized; at the time of extrusion shaping, the liquid metal in the transmission pipeline flows back, and the production efficiency is enhanced; and the friction and the abrasion of the extrusion punching head and the extrusion chamber are reduced, and the service lives of the extrusion punching head and the extrusion chamber are enhanced.

The invention relates to a method and to a device for homogenizing a glass melt in a melt receptacle, wherein at least one stirring device (10, 11) is disposed in the melt receptacle, which comprises a stirrer shaft (10) and a plurality of stirrer blades (11), and wherein a gap (16) is formed between a wall region of the melt receptacle (2) and the stirrer blades (11).According to the invention, the respective stirring device causes an axial feed action in an inner stirring region (12) between the stirrer shaft (10) and the stirrer blades (11) in order to feed the melt in the stirring region along the stirrer shaft (10). A melt flow brought about by the axial feed action seals the gap (16) against direct passage of the melt.According to the invention, a very high gap width can be achieved, thus preventing the abrasion of materials in the region of the marginal gap. This also reduces the complexity required for adjusting the device. According to the invention, a high level of homogenization can be achieved regardless of the entry point of the inhomogeneities.
