Title: Extraction column provided with a system for fast mounting,replacing and dismounting the shaft elements
Inventor: BLANCHARD JEAN-CLAUDE
IPC: B01L3/00
Filed: 1997-09-29
Abstract: The extraction column is provided with a practical and fast system for mounting, replacing and dismounting the elements of the shaft (2) of the upper decanter (18) and of the lower decanter (19). The intermediate parts (14) are mounted on fixing means (10) resilient with respect to the support (1). The different elements of the extraction column are mounted on these intermediate parts, compressed by fixing screws (26) placed at the top of the column. The unscrewing of these screws (26) enables, by means of the spring-back (10), the unscrewing of each constituent elements and its quick replacement, without specific tools. The invention is useful for extraction columns using solvent.

Abstract: There is described a method for introducing a substance into a cell, such as DNA, which comprises: (a) contacting the cell with a cell recognition agent, such as an antibody, (b) separating the recognition agent from the cell so that a portion of the cell membrane is removed thereby leaving a hole in the cell surface. Preferably the recognition agent is attached to a solid surface such as a silica bead or magnetic microsphere. The osmolarity of the transfection medium is selected to facilitate optimum pore formation and lies between 30-1200 mOsm, preferably 40-100 mOsm.

Title: A random binary signal generator with a narrowed autocorrelation function
Inventor: SZAJNOWSKI WIESLAW JERZY
IPC: H03K3/84
Filed: 1999-08-05
Abstract: A random binary signal is generated using a plurality of physical noise sources PNS. The outputs of the sources are multiplied together by analogue multipliers AM to increase the number of zero crossings. A zero-crossing detector ZCD produces a binary signal from the product signal. The spectrum-shaping filters SSF may have an approximately Gaussian power transfer function. The plural noise sources may be replaced by a single noise source and a number of delay lines (figure 5). The output of each noise source may be converted to a binary signal and then combined by logic gates (XOR, figure 7). The technique may be applied to a radar system.

Title: High rate run length limited (RLL) modulation encoders/decoders
Inventor: PATAPOUTIAN ARA
IPC: H03M13/31
Filed: 1999-12-24
Abstract: A modulation encoder 14 includes a base conversion circuit 23 that converts a partitioned input data stream from a first base representation (e.g. base 16) into a second (e.g. base 15) in accordance with the size of groups of bits. Intermediate values in the second base representation are formed and a residual value logic 26 performs modulo-arithmetic, the result of which is fed to a one's complement logic 28 to produce output codewords. The modulation decoder (fig. 3) performs an inverse process to arrive at the original data. The invention provides a high code rate (e.g. 32/33) with a low value constraint length (k), e.g. the maximum number of consecutive zeros being 6, that is relatively easy to implement. Application is to magnetic storage systems, in particular tape drives.

Title: Method for manufacturing electrochemical sensors made of metal and the sensor made by said method
Inventor: LESZLAUER ZOLTAN
IPC: G01N27/30
Filed: 1992-04-22
Abstract: A process is disclosed for producing electrochemical sensors made of metal. A contact element made of a metal having a higher melting point than the metal of which the sensor is made is connected to the material of which the sensor is made. A pipe is made of the same metal than the contact element, the pipe is secured in a predetermined, preferably vertical, position. The pipe (1) is filled with a powder produced from the same metal of which the electrode is made and the whole structure is heated up above the melting point of the metal of which the electrode is made in a closed oven in a vacuum or in a protective gas atmosphere. The powdered electrode material melts and the molten powder is cooled down until it solidifies in a vacuum or in the protective gas atmosphere. Alternatively, both ends of the pipe may be closed before heating. Also disclosed is an electrochemical sensor produced according to this process having a sensor surface made of particularly pure magnesium, rare earth metal, gold, platinum or aluminium or of an alloy of such metals, as well as a contact element metallically connected thereto. The electrode material is arranged inside a pipe made of a metal having a higher melting point than the electrode material.

Abstract: A contact lens for use on a patient's eye with an asymmetric aspheric cornea, the lens having an anterior surface, a posterior surface and a base, the posterior surface having a peripheral portion which is asymmetric and aspherical and at least coextensive with the base of the lens. The peripheral portion asymmetrically and aspherically matching a corresponding peripheral portion of the cornea which lies under the peripheral portion of the lens when the lens is worn in the patient's eye.

Title: Optical system for a sighting device
IPC: G01S17/08
Filed: 1984-05-03
Abstract: An optical system for a periscope-like sighting device is proposed for the localization, tracking and measurement of a target and comprises a plurality of optical elements as well as a laser range-finder essentially comprising transmitter and receiver portions. In this optical system, the visible and invisible radiation mutually parallelly incident upon a main mirror rotatable about a first axis and pivotable about a second axis is reflected to a first deflection prism. The first deflection prism deflects the radiation at substantially right angles through an objective lens to a first beam-splitter. The first beam-splitter deflects the invisible laser radiation to the receiver portion and transmits the visible radiation to a second beam-splitter and thence to a second deflection prism and an ocular. For achieving a view of the field of observation or a tracking of the target, or both, a television camera can be arranged on the side of the housing of the sighting device.

Title: Energy economizer controlled-current start and protection for induction motors
IPC: H02P1/28
Filed: 1985-04-09
Abstract: A standard, unmodified induction motor (11) starts with reduced input current, energy consumption and mechanical stress and is further protected from AC power source "phase loss", excessively low or high voltage or a locked-rotor condition during start-up or any subsequent moment while running when its stator winding (13,14,15) is energized from a sine wave source (300) thrkough a signal-responsive wave modifier EET-IC operative to control the portion of each cycle of the sine wave which is coupled from said source to the stator winding. A stator current sampling arrangement (6, 7, 8), and a motor current demodulator responsive to the first few hundred microseconds of stator winding initial inrush current each time said current increases from zero cooperate under certain conditions to produce signals for controlling associated wave modifier means, thereby to achieve a preferred magnitude of motor starting current under rated load conditions and achieve near-optimum motor operating efficiency during start-up and subsequent running with reduced loads and associated motor protection means (4) which inhibits said wave modifier means thereby to de- energise said stator winding under locked-rotor conditions that occur when motor start-up is attempted or later when the motor is running, or an AC power source anomaly occurs which would otherwise cause start-up stalling, excessive motor running current or motor stalling under rated loads.
