Abstract: The invention provides an improved means of producing the refrigeration required for any fractional distillation air separation process. The improved refrigeration technique causes the distillation columns to operate more efficiently, and thereby permits increased recovery and/or purity of product at lower energy input. Referring to FIG. 3, refrigeration air is partially expanded in expander 313, then condensed by exchanging latent heat with depressurized kettle liquid in condenser 314, and the resulting liquid air is split and used to reflux both columns 307 and 305 via pump 316 and valve 315 respectively.

Abstract: A wearable-type glucose sensor for continuously or intermittently determining the glucose content comprises a short hollow fiber (2) to be positioned in the subcutaneous tissue. This hollow fiber is connected via tubes (3,4) with component parts (5 . . . 12) located outside the body, such as a measuring unit (11). When a perfusion fluid containing the enzyme glucose oxidase is passed through the hollow fiber, a subcutaneous dialysis will take place in which some glucose dissolves in the perfusion fluid through the wall of the hollow fiber. This glucose is completely oxidized by the oxygen dissolved in the perfusion fluid in the presence of the glucose oxidase. By means of the measuring unit the resultant amount of H2O2 or, preferably, the employed amount of O2 is determined, both of which are a measure of the subcutaneous glucose concentration.

Abstract: A combined array for multiplication and division is built up from array cells arranged in n rows and m columns and n edge cells arranged at the edge of the array. The array cell construction corresponds to that of a division array cell. The addition of the number "0" of a row, which is necessary in a multiplication by "0", is effected by   1) switching over the multiplexer of the array cell and thus by gating out the addition and 2) gating out the overflow of the row by means of a logic circuit in the edge cell.   A multiplexer in the edge cell of each row controls the selection for multiplying or dividing and ensures that, on the one hand the multiplier or the overflow drives the multiplexer of the array cell. <IMAGE>

Abstract: AC switches (TRH, TRN) are connected in both the main and standby filament circuit of a signalling lamp (L). As long as the main filament (HF) is switched on and is intact, the main filament AC switch (TRH) is switched through via input diodes, connected in reverse-parallel, of an optocoupler (U1). When current is flowing through the input diodes, the photo-transistor of this optocoupler controls a switch (S1) which is used, in this switching state, to switch off the input diode of an electro-optical AC switch (U2). If the main filament (HF) burns out and the switch (S1) is driven into the other position, the electro-optically controlled AC switch (U2) is switched through and, for its part, switches the standby filament AC switch (TRN) through. The feedback report on the operating state of the signal lamp to the control mechanism takes place via the optocoupler (U3). The main/standby filament switch is constructed using only a few, proven electronic components. It is used especially in railway signalling lights. <IMAGE>

Abstract: M-center luminescence is used to measure radiation. An LiF crystal is excited with a 442 nm He-Cd laser because absorption measurements in LiF indicate the peak of the M-center absorption occurs at 443 nm. Laser stimulation produces an excited state of the M-center, which undergoes a very strong Stokes' shift. The peak of the M-center emission spectrum occurs at 665 nm with a half-width of 0.36 ev. Since the excitation wavelength differs significantly from the emission wavelength, measurement of the deep red emission can be done simultaneously with the excitation. The population of M-centers grows with increasing radiation damage, and therefore M-center lunimescence provides a basis for radiation dosimetry.
