Hadamard transformer using charge transfer devices. The transformer comprises a charging register with at least N electrodes and doped bands making it possible to transfer the N samples charged in the charging register to the transformer calculating register.

Method and apparatus are provided for carrying out multiple simultaneous transfers of fluid. The method and apparatus are particularly directed toward immunoassays wherein immunologically active compounds, such as antigens and haptens, are detected through their associated antibodies. The device relies on the ability to transfer fluids, such as biological samples and reagents, between a reservoir and an associated receptacle. By providing a receptacle having a port at its lower end and which is ...

An automatic rhythm performing apparatus capable of simultaneously producing a plurality of rhythmic tones having the optimum volume relationship irrespective of the total volume of the rhythmic tones. A plurality of rhythmic tone signal generating devices generate a plurality of rhythmic tone signals corresponding respectively to a plurality of rhythmic musical instruments. A combining device combines the rhythmic tone signals to provide a combined output signal as an output of this apparatus, ...

A streamline flow of aqueous cobalt (II) sulphate solution passes through a platinum tube which, as an anode, electrolyses the solution to cobalt (III). The flow, with a high surface concentration of nascent cobalt (III), falls into a volume of 1-methylnaphthalene in an organic solvent, and is recovered from underneath for recycling to the platinum tube anode. The cobalt (III) reacts with the 1-methylnaphthalene to form 1-naphthaldehyde. Other oxidations of organic reactants using nascent high-o...

This disclosure relates in general to a circuit for performing logic functions, and more in particular to a logic solid-state integrated circuit.

An apparatus and method for performing enzyme-linked immunological sandwich assays (ELISA) by affinity chromatography. Formation of the antibody-antigen-conjugate complex, and the development of a chromatophore indicator take place in a semi-automated, walk-away, fashion. The immunoassay apparatus comprises a chromatography tank, which further comprises a reaction compartment and a plurality of liquid solvent reservoirs, with a first-liquid reservoir being configured higher than a second-liquid ...

A process for performing catalytic reactions with intensive heat of reaction, in which a reaction mixture is conducted through a catalyst bed, from which the reaction heat is removed or to which it is fed by indirect heat exchange with a heat exchange medium. The catalyst bed adjoins at least one bed of a catalytically inert material, which also is in indirect heat exchange with the heat exchange medium.

A method of performing an endarterectomy comprising the steps of exposing the blood vessel containing the atheroma to be excised, next forming an incision through the wall of the blood vessel at a location subtended by the atheroma, then inserting a probe through the incision and imparting ultrasonic vibrations to the probe while manipulating the probe relative to the atheroma to loosen the atheroma from the surrounding blood vessel and extracting the loosened atheroma through the incision. The ...
