Inventor: GORDEZIANI VALENTINA SEMENOVNA
IPC: A23K10/28
Filed: 1985-02-25
Abstract: The present invention relates to a process for preparing a full-cream milk substitute for young domestic animals. The process consists in subjecting whey to fermentation. For that, acidophilic bacteria are first introduced into the whey at a temperature of 37-39 DEG C in an amount of 0.4 to 0.6% of the volume of whey, followed by propionate acid bacteria at a temperature of 30 to 32 DEG C in an amount of 1.5 to 2.5% of the volume of whey. The fermented whey is neutralised, after which it is mixed with a base consisting of milk and condensed fat, containing fat-soluble vitamins. The mixture obtained is homogenised and dried. The present invention can find application in the milk industry.

Title: Three-dimensional graphics acquisition system
IPC: G06F3/0346
Filed: 1986-10-02
Abstract: System including a stereoscopic viewing apparatus 1, by which the relief is visible with the aid of glasses 2, and a manipulator 3. The latter includes a ball 4 which the operator can move in a space 5, and which is held by wires 6 which join it to the vertices 7, 8, 9, 10 of the space 5. The wires 6 are used for measuring the X, Y, Z coordinates of the ball 4. Each of the wires 6, beyond this vertex, is wound round a cylinder 11, which drives a digital shaft encoder 12; the latter thus measures the distance from the ball to the corresponding vertex. The coordinates of the ball are then calculated as a function of its distances to the vertices 7, 8, 9, 10, then input into the stereoscopic viewing apparatus 1. By moving the ball 4, the operator thus inputs its X, Y, Z coordinates into the computer 13, while continuously comparing its position with that of the figures 14 already input.

The improvement relates to the profile of the teeth, particularly the teeth of the male rotor, so that there is a reduction of the phenomenon of wedging of the sealing, lubricating or cooling liquid molecules and a reduction of the wedging of the molecules of gaseous fluid between the bores and apices of the teeth. The improved profile of the teeth and the resulting reduction of the wedging phenomenon prevents a loss of power which is typical in the prior art screw-type rotary machines.
