Inventor: JHINGAN ANIL K
IPC: C12N15/09
Filed: 1991-12-24
Abstract: A novel method for the isolation of high molecular weight DNA from plants, yeast and bacteria using xanthate-forming compounds such as sodium/potassium ethyl xanthogenate is disclosed. The procedure does not require deproteination and yields clean DNA that is suitable for both PCR and Southern blotting. It can be utilized on a small scale without homogenizing the tissue. These features also facilitate automated screening of plant tissue samples, one of the labor-intensive techniques in molecular biology. This method is also adaptable for use in the field.

Abstract: A dispenser (401) has a pumping device (411) which has a support (413) with a plate-shaped support part (413a), a pump element (411) which can be pressed manually against the latter and at least one pump chamber (439). The latter is connected by means of an outlet valve (437) to the side of the pump element (431) which is accessible from the outside. The pump element (431) and the outlet valve (437) are formed by an elastic diaphragm (433a) which has an outlet hole (433c), and by an essentially dimensionally stable disc (435) which is connected to said diaphragm. When the pump element (431) is non-operative the outlet valve (437) is closed, in which case at most a very small amount of the product to be stored which is present in any case in the outlet hole (433c) can come into contact with the ambient air. If a person manually presses the pump element (431) against the aforesaid support part (413a), the product (451) to be dispensed opens the outlet valve (437).

Abstract: A method for establishing and terminating a connection in an emergency calling system and a device to carry out the method. An emergency telephone station (NSS) can be connected to an answering station (AS) via a telephone station interface (SI), the public telephone network and an answering interface (AI). The establishment and termination of a connection are controlled by the telephone station interface (SI) and the answering interface (AI). The telephone station interface transmits dialling signals and, at the request of the answering interface, identification signals. Once the loop has closed on the answering interface, the latter transmits a call initiation signal to the telephone station interface. The speech path is through-connected and timers for limiting the call time are set in the answering interface and in the telephone station interface. The timer in the answering interface is constantly reset, provided that the loop remains closed there, and an AF reset signal is supplied to the telephone station interface by means of which the timer in the telephone station interface is also reset. Once the loop has been opened in the answering station, an AF cleardown signal is transmitted to the telephone station interface by means of which the loop is opened there and the emergency telephone station is switched back to the idle condition. <IMAGE>

Abstract: The invention relates to a procedure and an apparatus for adjusting the speed of an induction machine (1) fed by a frequency converter or an inverter (2) to a value corresponding to a reference value (f R ). In the procedure, a frequency signal (n m ) depending on the speed of the motor is generated and the reference value (f F ) of the motor speed is corrected by means of a correction signal (C) proportional to the slip of the motor. The corrected reference value is used as a frequency reference (f s ) for the frequency converter or inverter. According to the invention, the correction signal (C) proportional to the slip is generated with the aid of the frequency signal (n m ) depending on the motor speed and another frequency signal (n s ') formed from the frequency reference (f s ) of the inverter. When the motor speed changes e.g. due to variation in the load, the reference frequency of the inverter is corrected correspondingly.

Abstract: A relatively low resolution touch screen system is utilized in a graphic display environment wherein the resolution of the graphic display is relatively high. The character resolution yields a lower target resolution, a single character being the target (or the desired character). The method zooms a predetermined number of characters around an initially reported position, the zooming increasing the character resolution such that target resolution is decreased to a value resulting in a touch screen resolution at least equal to or higher than resolution of the target resolution. Further, as the stylus is moved toward the desired character, a new position of the stylus is calculated. A check is made to determine if the new position is within the zoomed area. If it is, the processing continues; otherwise the screen is rezoomed around the new position. When the desired character is under the pointing element, the pointing element utilized to reverse the calculation thereby identifying the position of the desired character, and thus the desired character itself.
