Abstract: Methods for separating casein from soluble proteins in a composition. The method includes: adding a phosphate solution to the composition, mixing to form a mixture, freezing the mixture to obtain a frozen mixture, thawing the frozen mixture to obtain casein-containing aggregates in the mixture, and then centrifuging the mixture to obtain a supernatant traction and a casein-precipitate fraction. The supernatant fraction contains the soluble protein, which may be isolated by subjecting the supernatant fraction to a purification process. The method can be applied to purify a recombinant protein from the milk of a transgenic mammal.

Abstract: A finger-controlled device for pushing slide bars, including two sets of data carriers, two slide bars and a finger-controlled section for moving the slide bars. Each data carrier corresponds to a sensor for reading 0, 1 signals. Each data carrier has a central shaft disposed with a gear. A face of each slide bar is formed with a rack facing the central shaft for meshing with the gears. The finger-controlled section is movable relative to a housing having an interior chambers for receiving the data carriers, sensors and slide bars. Four side walls of the chamber are formed with through holes for the slide bars to pass therethrough. The housing restrains the slide bars to move relative to and across each other. In operation, the slide bars are moved relative to each other as the finger-controlled section is moved, whereby the data carriers are rotated by a fixed number of circles for use in absolute coordinate input alignment. The slide bars can be widened and thickened to have greater bending strength.

In such an arrangement, the displacement of the finger controllable member in X-axis and Y-axis direction may be detected as coordinate date. The detected coordinate data is transmitted to a control circuit for further processes and then sent to a computer device.

Abstract: This is an improvement of a cursor positioning apparatus for a computer display device which includes an upper case, a center body and a lower case. It controls the movement and positioning of a cursor through the sliding movement of X-axis and Y-axis. There are also photo electric components for detecting the movement of photo grid and the displacement of the sliding bar in X-axis and Y-axis. The sensing signals are sent to a control circuit board and computer for further processing. The present invention may further have a curve-shaped slot in the upper case engaging with a square center pillar in the center body. The center pillar further engages with the lower case, and thus becomes an integral part of a keyboard. The present invention can be rotationally operated about a fixed axis point. A user can use hand and wrist to control the movement and positioning of the cursor on a display device without moving the arm. It is better ergonomically designed and structured than the conventional mouse.
