Patent EP-0243659-B1 (EP)
IPC: B41B19/00
Filed: 1987-03-20
Granted: 1990-12-27
Abstract: An area exposure apparatus for exposing a text on a recording carrier and a method for the area exposure is disclosed. In accordance with the device configuration, text is exposed on a recording carrier (12) which continuously moved forward in a forward move direction. To this end, the recording carrier is scanned over a maximum area and consequently exposed by means of an intensity modulated laser beam along scanning lines (Z1, Z2) at right angles relative to the forward move direction, and coupled in a predetermined manner to the forward movement. The scanning lines formed by the scanning extend over a plurality of characters of the text. For the exposure of the recording carrier with a text which exceeds a given length to width ratio, and has a predetermined narrower width than the recording carrier, which is hence relatively narrow, the recording carrier (12) is shifted in the direction of the lines of the text and at the same time is scanned in the direction of the height of the characters of the text.

Granted: 1991-01-16
Abstract: A control circuit for controlling a known active harmonic filter operating as a step-up converter in a power supply with sinusoidal network current input and a power factor of almost unity. The step-up converter comprises: a main rectifier, a storage inductance (LS), a cross-connected high-speed transistor (TQ), a diode (D1) and a power storage capacitor (CL). The high-speed transistor (TQ) is controlled by a first threshold switch (STc) whose input is controlled by a control capacitor (C12) coupled to receive a signal representative of instantaneous rectified d.c. output voltage (UE), instantaneous power output voltage (Uo) and a signal representative of the charge state of the inductance. The inductance charge signal is obtained from a voltage jump (ringing voltage) between the inductance and the diode (D1) by sensing a flank of an oscillation voltage occurring at the diode by a RC circuit (R8, C10), which triggers a second threshold switch (STa) to control charge reversal and recharge of the capacitor (C12), thus determining the time instants of operation of the first threshold switch to control the cross-connected electronic switch (TQ) to conduction, and hence re-storing of electrical energy in the inductance.

Title: Automatic immunochemistry analyzing apparatus and method
IPC: G01N21/51
Filed: 1986-12-22
Granted: 1992-04-01
Abstract: A system for analyzing a chemical reaction provides control of the temperature and volume of the reagents to improve the accuracy and precision in quantitive measurements of specific proteins and other immunochemistries in body fluids. The reaction occurs in a cuvette (48, 50) within a nephelometric optics module (44, 46). A sensor (246, 248) senses the temperatures of reaction buffer liquids as they flow into the cuvette (48, 50), and a heat exchanging device (250, 252) increases or decreases the temperatures of the buffer liquids. A control circuit (242) responsive to the temperature sensor (246, 248) controls the heat exchanging device (218) to maintain the temperature of the buffer liquids and the cuvette (48, 50) within a selected temperature range. The system may also include a sample pickup station (18), sample probe (22) means for withdrawing a selected sample from the sample pickup station (18), a sample preparation station, and sample transport (20) means for carrying said sample from the sample preparation station to the reaction cuvette (48, 50). The system may include an antibody pickup station (108), antibody probe (110) means for withdrawing an antibody from the antibody pickup station (108), an antibody preparation station, and antibody transport (106) means for carrying the antibody from the antibody preparation station to the reaction cuvette (48, 50).

Abstract: A bogie with a wheel set automatic control system which is independent of the superstructure is proposed. The said automatic control system contains, in combination with a hollow profile for the wheels of the wheel set (2 and 4, respectively) and a primary suspension (22) which is elastic in the longitudinal direction of the bogie, two lever systems (26.1, 26.2) which are self-adjusting independently of one another, are each arranged on one longitudinal side of a running gear, forcibly couple the axle ends, on the same rails, of the two wheel sets (2, 4) in the longitudinal direction of the bogie so as to be movable in opposite directions only and are each provided with a deflection element (30) which is swivellably mounted on the bogie frame (18), the swivel movements of which element are damped by a single damper (42) assigned to each lever system, by which means, in a constructionally simple and robust manner requiring little maintenance, an optimum limitation of the freedom of movement of the wheel set in the longitudinal direction of the frame relative to the bogie frame is achieved with a view to a radial self-adjustment in curved tracks and simultaneous high degree of running stability at high travelling speeds.

Title: Multi-layered printable identity card and method for its manufacture
IPC: B42D25/41
Filed: 1988-09-21
Granted: 1992-06-10
Abstract: An identity card is provided with a character set usable as a printing block, whereby the "natural foamability" that laser action brings about in the plastic materials commonly used for identity cards, such as PVC and polycarbonate, is exploited to obtain a relief height sufficient for a clear impression of the characters. The standard total height of the embossed characters relative to the rest of the card surface is reached by an additional deformation of the card body in the embossed character area so as to form flat underlying the characters.

Granted: 1991-05-15
Abstract: In order to analyse metal particles for their chemical composition and to obtain a sorting signal, a method and device are proposed in which the particles (1) are subjected to a pulsed laser beam (6, 8, 9, 10) and partially vaporised to form a plasma, purified thereby and subsequently the purified location is partially vaporised by means of a pulsed laser beam to form a plasma and the spectral lines of the plasma are used to identify (11, 14) the metal particles. The required measuring frequency of 30 particles per second can easily be attained and exceeded when a specific narrow waveband or a specific wavelength is filtered (11) out of the total radiation emitted by the plasma, and when the ratios of the intensities of the filtered-out component beams are formed and from the values of these ratios a sorting signal is obtained by comparison with adjustable limiting values. Moreover, the rate of measurement can be improved owing to the fact that the component beam is used for comparison only during a specific time interval.

Abstract: Fibers and filaments of an ultrahigh molecular weight polyolefin that have a void volume greater than about 20% and are wettable. Wettability is imparted to the fibers and filaments by incorporating a filler into the composition that is hygroscopic, has a particle size less than about 10 microns in diameter and a surface area greater than about 30 square meters per gram. The preferred fillers are those that contain surface silanol groups. The fibers and filaments are formed by the process of forming a mixture of the ultrahigh molecular weight polyolefin, filler and plasticizer, metering the mixture to an extruder, heating and kneading the blend in the extruder, conveying the extrudate to a spinneret-type die, expressing the extrudate through the die openings to form fibers or filaments, and extracting at least a portion of the extractable plasticizer to provide the desired porosity. The fibers and filaments may be formed into woven and nonwoven webs by airlaying and wetlaying techniques. Such webs are particularly useful as a battery separator.
