Abstract: The invention provides cellulose acetate hollow fibers suitable for use in artificial kidneys which provide superior water and solute clearances. The cellulose acetate hollow fibers of this invention may be made from a molten mixture of 41-50% cellulose acetate, 30-57% polyethylene glycol (MW150-600) and 2-20% glycerine, the resultant fibers being cold drawn by 2-20% and then leached to remove the polyethylene glycol and glycerine. The hollow fibers of the invention have an internal diameter of 100 to 350 microns, a wall thickness of 20 to 60 microns, and ultra-filtration coefficient of 2 to 6 millilitres per hour per square meter per millimeter of mercury and a urea coefficient of 0.015 to 0.045 centimeters per minute.
Patent IT-1106295-B (IT)
IPC: C12N1/16
Filed: 1978-09-04
Granted: 1985-11-11
Abstract: PURPOSE:To provide a method for the continuous stable culturing of microorganisms, and to improve the culturing efficiency, by using a bubble column fermentor or an air-lift fermentor, and culturing aerobically while controlling the gas/liquid maxing ratio in the fermentor. CONSTITUTION:In the aerobic culturing of yeast, bacteria, etc., in a bubble column or an air-lift fermentor, the culturing is conducted while controlling the gas/liquid mixing ratio within 0.3-0.9, pref. 0.5-0.8 by manually or automatically adjusting the amount of a anti-foaming agent or a surface active agent added to the fermentor, or the rae of aeration. The gas/liquid maxing ratio can be determined by measuring the pressures at two points of the fermentor, which are different in height, with diaphragms, and transmitting the pressures through capillaries to the high-pressure and the low pressure sides of a pressure difference gauge.

Title: Decoding of colour TV signals in PAL and SECAM systems - uses identification pulses transmitted during SECAM vertical sweep pulse emission
Inventor: APOSTOL MILCHEV APOSTOLOV
IPC: H03D/
Filed: 1977-11-02
Granted: 1985-06-26
Abstract: The colour television signal decoding method is designed for use with automatically switched PAL-SECAM systems. It is based upon the common amplification of PAL and SECAM chromatic signals and separate demodulation of these signals. The identification of chromatic difference signals (R-Y) and (B-Y) is carried out by circuits having the chromatic carrier frequency. This frequency is transmitted behind the horizontal sweep pulses for PAL and SECAM received signals. The identification pulses, transmitted during vertical sweep pulse emission in the SECAM system, are used to identify the type of TV signal PAL or SECAM received. These signals are separated in accordance with a code. They are selected according to the frequency of the integral TV signal. They are then frequency amplified and demodulated to produce control voltages. These control voltages are used to switch the chromatic signal to the corresponding PAL or SECAM demodulator.
