Title: Current source arrangement
IPC: H03M1/00
Filed: 1984-02-03
Granted: 1987-11-11
Abstract: In a digital-to-analog converter (1) a plurality of binary weighted currents are generated, which currents must be in an accurate current ratio relative to each other. By means of a coupling network (15) which is controlled by a control circuit (17), a plurality of currents from said digital-to-analog converter (1) can be coupled to a precision current-mirror circuit (25) in accordance with a cyclic pattern, this allowing deviations in the ratios of the currents from the digital-to-analog converter (1) to be detected by detection means (80) which control correction means (18.2 to 18.16) by means of which the currents from the digital-to-analog converter (1) are corrected so as to reduce the detected deviations.

Abstract: The froth floatation device (10) includes a floatation column (12) partially filled with packing (24) which defines a large number of small flow passages extending in a circuitous pattern between the upper (14) and lower portions (16) of the column. A conditioned aqueous pulp of mineral ore, such as iron ore is introduced into the midzone of the column (12) through a pulp inlet (18). A pressurized inert gas such as air is introduced into the bottom of the column (12) through a gas inlet (22) and is forced upwardly through the flow passages in the packing (24). As the air flows upwardly through these flow passages, it is broken into fine bubbles which intimately contact the floatable particles (e.g. iron oxide) in the aqueous pulp and forms a froth concentrate (25) or float fraction which overflows from the top of the column (12) through an outlet (28). Wash water is introduced into the top of the column (12) through a water inlet (20) and flows through flow passages in the packing countercurrently to the float fraction to scrub entrainable non-floatable particles (e.g. gangue) from the froth concentrate (25). A tailing fraction (33) containing non-floatable particles is withdrawn from the bottom of the column (12) through an outlet (34).

Abstract: A felting of synthetic fibers having an embossed pattern that forms depressions in at least one surface of the felting is disclosed. The surface of the felting with depressions contains, in at least the area of the depressions, a layer of small hollow spheres that are bonded to one another and to the felting by means of a binding agent. The layer of hollow spheres fills up, at least partially, the depressions in the surface of the felting produced by embossing. This reinforces and strengthens the thinner areas of felting in the vicinity of these depressions. When the reinforced felting is applied to a shoe upper, for example, the resulting upper has improved stiffness and strength. Furthermore, the excessive penetration of adhesive into the felting, which can cause a spotty or uneven appearance of the reinforced upper, is prevented. Resistance to splitting and separating is likewise improved.

Abstract: This invention pertains to a three-phase reversing contactor with fixed-mounted contact parts serving the input and the output, and a connection by contact bridges from the input to the output. A common drive mechanism is provided for all the contact bridges, and a shift mechanism to change the configuration of the contact bridges, while in the OPEN position, relative to the fixed-mounted contact parts is also provided. Through the application of the two independently movable contact bridge carriers, which by use of an auxiliary magnet can be selectively brought into functional contact with the common drive mechanism by a reversing yoke, the drive output for the auxiliary magnets can be kept low. As there is a fixed configuration of contact bridges to the fixed-mounted contact parts, the major wiring work can be performed in the shop by the use of correspondingly formed fixed-mounted contact parts.

Abstract: An electrochemical specific binding assay of a ligand (e.g. antigen, hapten or antibody) wherein at least one of the components is enzyme-labelled, and which includes the step of determining the extent to which the transfer of electrons between the enzyme substrate and an electrode, associated with the substrate reaction, is perturbed by complex formation and/or by controlled external influences.The electron transfer is aided by electron-transfer mediators which can accept electrons from the enzyme and donate them to the electrode or vice versa (e.g. ferrocene) or by electron-transfer promoters which retain the enzyme in close proximity with the electrode without themselves taking up a formal charge. Alternatively an apoenzyme label may be employed, in which case electron transfer may be aided by the cofactor of the apoenzyme immobilised on the electrode.The electrochemical apparatus will typically comprise two or three electrodes, including one working electrode onto which components may advantageously be immobilised.When controlled external influences are employed, they may comprise displacement of the complex formed relative to the unbound enzyme-labelled component.The use of direct electrochemical measurement of the enzyme label avoids the errors and inconvenience of the known indirect measurement techniques.

Abstract: Process for preparing 2,2'-disubstituted-1,3-dioxolane-4-methanol compounds having formula (I), wherein R1 and R2 are each independently hydrogen, alkyl, cycloalkyl or R1 and R2 together with the carbon atom form a 3 to 6 member cycloalkyl group, or aryl, the process comprising: reacting D- or L-serine with a nitrosating agent in an aqueous solution in the presence of formic acid, acetic acid, or propanoic acid to prepare 2,3-dihydroxypropanoic acid (D- or L-glyceric acid), the aqueous solution comprising from about 0.1 to 0.5 liter of water per mole of the serine starting material; reacting the glyceric acid so formed with 2,2-dimethoxypropane in the presence of a loweralkyl alcohol to prepare the D- or L-glyceric acid alkyl ester which is reacted with a selected aldehyde or ketone or the acetal or ketal derivative to prepare the corresponding 1,3-dioxolane derivative. Reacting the 1,3-dioxolane derivative with lithium aluminum hydride provides the desired 2,2'-disubstituted-1,3-dioxolane-4-methanol derivative. If an alcohol is not used as described above, then the 2,3-dihydroxy-propanoic acid is reacted with a selected aldehyde or ketone or the acetal or ketal derivative to prepare the 1,3-dioxolane derivative. The dioxolane derivative is then reacted with lithium aluminum hydride to provide the desired 2,2'-disubstituted-1,3-dioxolane-4-methanol derivative. The compounds so prepared are intermediates in the preparation of optically active beta-agonists or antagonists.

Abstract: An electronic fuse is intended to be triggered should the current from a load (LA) exceed a predetermined value. The load current is restricted first by a switch in series with the load, the switch being kept in a closed or open state by pulses from a pulse length modulator (PB). The pulse length of the modulator is controlled by a sensing circuit (AK) such that when the load current exceeds the predetermined value, the circuit sends a control signal varying as the load current, so that the closing time of the switch (OM) decreases with increasing load current. After a practically constant time the switch is thereafter set to a permanently open state.

Abstract: A method and apparatus for modifying corneal refractive properties includes a laser source, computer control, and a plurality of deflectors including at least one rotating and translating deflector. A beam emitted from the laser source is deflected by the rotating and translating deflector in a controlled manner such that the beam strikes the cornea tangentially, ablating or lathing the contacted surface. The apparatus is computer controlled to intra-operatively determine the visual axis, monitor fixation, monitor changing refractive error, adjust the rotating and translating deflector and activate and deactivate the laser. The invention allows the radius of curvature of the cornea to be modified in vivo or in vitro. The cornea is lathed tangentially in either a natural or frozen state in an area centered about its optical axis, encompassing its optical zone. In one embodiment, a rotating arm, rotating in a plane perpendicular to the optical axis of the cornea, transmits the laser beam to the variable deflector.
