Abstract: A method for locating a mobile transmitter (M) is specified which only needs the transmitted baseband signal (y1(t), y2(t), y3(t)). This must be received by at least two stationary and mutually synchronised base stations (B1, ..., B3). For determining the relative transit times, the baseband signal (y1(t), y2(t), y3(t)) received in each of the at least two base stations (B1, ..., B3) is demodulated within a time interval predetermined in each case to form a data sequence (c1, c2, c3). The various data sequences are correlated with one another to determine the relative transit times which are greater than a time interval T between the digital data. To obtain a possibly required fine resolution of the transit times within a time interval T, a time displacement of the baseband-related synchronisation with respect to the uniform time frame is used. <IMAGE>

Title: A method for killing cells without cell lysis.
Inventor: LAWLIS VIRGIL B JR
IPC: C12N1/00
Filed: 1990-06-13
Abstract: This invention provides a method for killing fungal cells without lysing in fermentation processes in order to prepare the fermentation mixture for processing to recover or extract an extracellularly expressed enzyme from the fermentation mixture. A preferred method of this invention comprises adjusting the pH of the fermentation mixture to less than 2.79 using a mineral acid, then adding sufficient acetic acid to the mixture to affect a substantially complete cell kill in mixture. A salt of the acetic acid can be used. The organic acid or salt can be added, then the pH adjusted to the desired level. Other organic acids can be used, in which case the pH of the mixture is adjusted to the pKa of the selected organic acid before the organic acid is added to the mixture. The method of this invention is useful for stopping the growth and killing the cells in any micro-organism, culture or fermentation such as those containing yeast, bacteria or fungi and is particularly useful in systems where it is desired to kill the cells without lysing them.
