5158889 BIOLOGICAL CELL SORTER Shin-ichi Hirako, Yoshihir Nakatsuji, Nagaokakyo, Japan assigned to Omron Corporation A biological cell sorter, comprising: a first laser for emitting a first laser beam directed to a point in a tube conducting biological cells in a single file, a first light detector for detecting a cell to be destroyed according to a light emitted from the cell as a result of impinging the first laser beam upon the cell and producing a trigger signal when a cell to be destroyed is detected; a second laser for emitting a second laser beam directed to another point in said guide path downstream of the mentioned point when the trigger signal is supplied thereto; a delay circuit for delaying activation of the second laser by a delay time corresponding to a travel time which the cell requires to travel between the two points; a time measuring circuit for measuring a time interval between two succeeding trigger signals; and a correction circuit such as a look-up table for adjusting the delay time according to said time interval between the two succeeding trigger signals. Thus, even when the response time of the second laser beam is affected by the frequency of second laser beam emission, it is possible to destroy the cells to be destroyed with an extremely high precision. Owing to the high precision achieved by the present invention, the second laser beam can be accurately directed to the intended cells, and the power efficiency of the second laser can be improved.

must in a turbulent flow to the vat and to a hydraulic stirring device positioned in the bottom portion of the vat for stirring must in the vat. A gas injection device is connected to an upper portion of the return pipe for introducing gas into the flow of must in the pipe. Alcohol may be collected by a decanter connected to the return pipe and/or by a device for heating the must in the pumping column.
5158895 AUTOMATIC IMMUNOLOGICAL MEASURING SYSTEM Yoshihiro Ashihara, Isao Nishizono, Hidetaka Minakawa, Masahisa Okada, Yasusuke Sakurabayashi, Fumio Watanabe, Shin-ichi Wakana, Tokyo, Japan assigned to Fujirebio Inc An automatic immunoassay apparatus utilizes cartridges each having at least two wells, a first well containing solid phase material carrying antigen or antibody, and a second well containing antibody or antigen labelled with labelling compound. The wells may be sealed with a suitable sealing film before use and the sealing film is broken when the cartridge is to be used. The cartridges are transported to a predetermined position on a steppingly movable reaction line and conveyed thereby at a predetermined interval. While the reaction line steps, a sample, labelled antigen or antibody contained in the second well and substrate, if necessary, are added to the first well and stirred at predetermined timings, and reactions between the sample and a reactive solution are measured under control of a control device having a memory storing operator selectable programs for various measuring methods.
FERMENTER FOR THE PRODUCTION OF ALCOHOL Vladimir Kalina, Lausanne, Switzerland assigned to Nestec S A A fermentation apparatus for the production of alcohol provides for continuous circulation of must through the apparatus. A pumping column is connected to a top of a fermentation vat via a back pressure valve and extends above the vat for pumping fermented must transferred from the vat via the back pressure valve. A must degassing device is connected to the pumping column at a position above the column. A must return pipe is connected to the degassing device and to a bottom portion of the vat for conveying
