Methods are disclosed for providing a library of composite or novel composition samples on a support. The method involves depositing one or more components as concentration gradients on the surface of the support. The concentration gradients are placed on the support in the form of superimposed triangles which allow ready formation of composite or composition samples containing three or more components. The samples can be removed from the support by drilling out portions of the coated support so...

Methods are disclosed for providing a library of composite compositions on a support. The method involves depositing one or more components onto the support on either discrete spaced regions of the support or as a continuous concentration gradients on the surface of the support. The composite samples can be removed from the support by drilling out portions of the coated support so as to yield individual composite tablets containing the support with one or more component layers thereon. By using ...

A manual combinatorial weighing apparatus having one or more weighing devices housed in a casing with each weighing device having a scale plate for placing articles thereon, and indicators associated with the weighing devices for indicating selected weighing devices. As many weighing devices in casings as desired by the user are provided in a desired layout. Weight data items of the articles put on the scale plates are combined to find a weight combination giving a desired total weight. The sele...

A unipolar, RZ, constant width pulse telemetry is achieved in the combinatorial set, or any desired subset of pulse sequences thereof. Each input datum W is in one-to-one correspondence with a particular pulse sequence and the correspondence of datum with pulse sequence and vice versa is implemented by any selected ordering of the pulse sequences of the combinatorial set together with a successive comparison of the magnitude of the datum with the cumulative combinatorial capacity of the set.

A combinatorial weighing system designed for weighing out a desired number or weight of articles, wherein groups of articles are respectively weighed by a plurality of weighing machines, combinatorial addition is performed on all or a fixed number of possible combinations for weighed values obtained, a particular combination whose combination value is equal or the closest to a set value is selected, and articles are discharged from the weighing hoppers corresponding to the selected combination. ...

Ink-jet printing technology is applied to the creation of multi unit chemical compound libraries. Ink-jet type nozzles are used to inject multiple droplets onto the surface an appropriate support, such droplets consisting of solutions containing units of the chemical compound that will attach to the support surface. Droplets are then injected, by such nozzles, onto the support attached unit droplets that contain units that will attach to such support attached units. The second step is repeated t...

A combinatorial weighing system, wherein swing plate 9 disposed substantially in the middle of the interior of a feed hopper 1 uniformly distributes objects of weighing, particularly those liable to tangle each other, in the bottom of the feed hopper without causing localized gathering of the objects, and the objects are then transferred to conveyors 5 disposed close to each other at one of their respective ends and extending in mutually opposite directions until the other ends thereof are posit...

A method for packaging and identifying integrated circuits. The method includes providing integrated circuit packages each having a respective set of identifying electrical nodes coupled thereto. For each of the packages, a respective one of the integrated circuits is mounted therein. For each of the packages, members of the respective set of electrical nodes are electrically interconnected in a manner associated with a respective identity of the respective integrated circuit mounted therein. Fo...

A combinatorial weighing method and apparatus for obtaining a batch of articles of a plurality of categories, each category of articles in the batch having a predetermined weight or made up of a predetermined number of articles. The method includes the steps of setting a target value for each category of articles, and supplying a plurality of weighing machines, groups of which are provided for each category of articles, with the articles of the category corresponding thereto. For each category o...

A combinatorial weighing apparatus has chutes for distributing articles selected and discharged by combinatorial weighing operation to prescribed discharge positions. At least one means is coupled to the chutes for distributing articles discharged from weighing hoppers in a plurality of directions. A plurality of timing hoppers are provided which are capable of temporarily storing the articles distributed by the distributing means. Article receiving means is disposed for receiving the articles w...
