Patent EP-0196790-A2 (EP)
Inventor: TOMBLIN GRAHAM J
IPC: B01D57/02
Filed: 1986-03-04
Abstract: A process and apparatus for extracting DNA, which has relatively high molecular weight, from test samples and particularly from human whole blood samples; the extracted DNA is of usable volume and concentration, and is of such purity as to permit conventional restriction by a number of enzymes without the need for further purification. The apparatus consists essentially of an agarose gel disc, typically 5 mm. thick by 31 mm. in diameter, supported between two 8 micrometer polycarbonate filters in an electric field. Further, the method involves the loading of a suitably treated blood sample onto the top face of the agarose gel disc and then applying an electric field. Of the constituent parts of the treated blood, the DNA molecules are the largest with regard to molecular weight. Consequently, their passage through the agarose gel disc, under the force of the electric field, is impeded. All other constituent parts of the treated blood pass relatively rapidly through the disc and are removed. The DNA is then collected, and suitably stored in readiness for analysis.

Abstract: In Wechselstromnetzen treten unerwünschte Oberschwingun­gungen auf, insbesondere die zweite Harmonische. Um mit einfachen Mitteln eine wirksame Dämpfung dieser Ober­schwingungen zu erreichen, wird bei einem Blindleistungs­kompensator (9, 12; 10, 13), der über einen Blindlei­stungstransformator (8) und einen Stromwandler (17) an ein 50-Hz-Drehstromnetz (15) angeschlossen ist, ein zu­sätzlicher Stabilisierungskreis (21, 25 - 28, 23) in eine herkömmliche Strom-Spannungsregelung mit einem Strom­Spannungsregler (22) und einem dreiphasigen Zündimpuls­generator (24) eingebaut Der Blindleistungskompensator weist für jede Phase des Drehstromes mindestens eine Luftdrossel (9) auf, die über einen Stromwandler (19) und über einen Wechselstromschalter (12) mit antiparalle­len Thyristoren über einen weiteren Summenstromwandler (18) an eine Sekundärwicklung des Blindleistungstransfor­mators (8) angeschlossen ist. Zusätzlich weist der Blind­leistungskompensator je Phase des Drehstromes mindestens eine Kondensatorbank oder einen Kondensator (10) auf, der über einen Stromwandler (20) und einen Wechselstrom­schalter (13) an den Summenstromwandler (20) angeschlos­sen ist. Der Stabilisierungskreis erfasst einen ober­schwingungshaltigen Magnetisierungsstrom als Differenz aus Kompensatorstrom (i K ) und Summenstrom (i Su ) primär- ­und sekundärseitig vom Blindleistungstransformator (8) und mittels eines Spannungswandlers (16) ein netzfre­quentes Spannungssignal (U), das proportional zur Netz­  spannung (U N ) ist. Diese beiden dreiphasigen Strom- und Spannungssignale werden in einem Blindleistungsmesser (25) in ein einziges Gleichspannungssignal (Q) umgewan­delt. Eine eingangsseitige Oberschwingung von 100 Hz tritt ausgangsseitig als 50-Hz-Signal auf, das in einem Bandpassfilter (26) herausgefiltert und nach einer +90° Phasenverschiebung (27) über einen zweiseitigen Begren­zer (28) in einem Addierglied (23) zu dem herkömmlichen Ausgangssignal des Strom-Spannungsreglers (22) addiert wird.

Abstract: This invention relates to transparent sheet material suitable for making transparencies in plain paper electrostatic copiers. 
     When transparent, polymeric sheets are imaged in a conventional electrostatic copying machine, static charge on the surfaces of the sheets causes them to jam the machine or to pass through the machine without having an image formed thereon. Jamming can be caused by multiple feedings of sheets, i.e. more than one sheet entering the imaging zone of the copier at the same time. Multiple feeding can result from two or more sheets clinging together on account of static charge or excessively high coefficient of friction. While excessively high coefficient of friction can be reduced by proper selection and/or treatment of the surface material of the transparency sheet, it is desired to provide treatment to the transparent sheet material to reduce static charge, thus resulting in fewer jams and fewer unimaged sheets. 
     This invention provides transparent sheet material for use in plain paper electrostatic copiers comprising (a) a flexible, transparent, heat resistant, polymeric film base, (b) an imaging receiving layer carried upon a first major surface of the film base, and (c) a layer of electrically conductive prime coat interposed between the image receiving layer and the film base. This sheet material can be used in either powder-toned or liquid-toned plain paper copiers for making transparencies.

Abstract: The method is used for controlling the tube wall thickness in a multi-stand continuous stretch-reducing mill having apparatus for measuring the tube wall thickness before forming and the run-in speed of the tube, a computer unit for processing the measured values and an apparatus for controlling the speed of the drive motors. In order to provide the possibility of evening out tube wall thicknesses which vary in short length portions of rolling stock, specifically in such a way that each cross-section of the rolling stock is formed with the maximum stretch or wall thickness reduction but not greater than that required for achieving a desired finished tube wall thickness, it is proposed that the ratios of the roll speeds are set continuously from roll stand to roll stand in accordance with a control law (e.g. wall thickness change to change in speed ratios) in dependence on the minimum value of the wall thickness values which are measured before forming and assigned to the portion of the rolling stock which is situated at the respective point in time in the region of the mill provided for influencing the wall thickness.

Abstract: An improved pulse width modulation technique (Fig. 4) provides for an increased sampling rate without an in­creased ON/OFF rate at associated control devices. Both ON/OFF (106) and OFF/ON (104) edges in a PWM signal are modulated. The system then samples (Fig. 4) at twice the pulse turn-on rate to provide more frequent sampling. System response time may be decreased without an increase in the operating frequency for the associated control device. Particular application of the present invention may be found in continuously variable transmission systems which utilize PWM-controlled electrohydraulic valves for ratio control (44), line pressure control (48) and clutch control (52).

Abstract: An automatic dialer is accessible to the public network directly or via a PBX. During registration mode, a controller is responsive to a unique keystroke input to store a binary 1 as a call identifier and a destination terminal number of the public network into a first storage location of a memory or store a binary 0 as a call identifier and a destination terminal number of the PBX into a second storage location of the memory. During call establishment mode, the controller is responsive to a replica of the unique keystroke input to recall data from a different location of the memory. When the dialer is connected to the PBX, the controller dials a network access digit, inserts a pause and dials the recalled destination terminal number if the recalled call identifier is binary 1 or only dials the recalled destination terminal number if the recalled call identifier is binary 0. When the dialer is connected to the PBX, the controller dials the recalled destination terminal number if the recalled call identifier is binary 1 or discards the recalled data if the recalled call identifier is binary 0.

Abstract: In a sensor (10) for determining a speed of rotation, which sensor is based on the principle of magnetic induction coupling, a transmitter coil (30) supplied with alternating current is fitted on a stationary transmitter part (11) and a receiver loop is fitted on a stationary receiver part (12). By means of the ventilation wing (13) of an asynchronous motor (14), the voltage induced in the receiver loop is varied in the periodic sequence of the tooth crests and tooth gaps. This gives a pulse sequence extending in proportion to the speed of rotation of the asynchronous motor (14). As a result of a particular refinement of the transmitter and receiver conductive paths, it is possible to eliminate extraneous influences and to detect the direction of rotation. <IMAGE>
