Abstract: A combination gravimetric and volumetric fluid dispenser is disclosed which includes a scale linked to a controller. The controller is linked to a plurality of two stage valves which control the dispensing of large quantities of base materials. The controller is also linked to a plurality of nutating pumps which together with the controller controls the dispensing of smaller quantities of additive materials. The dispensing system disclosed is particularly useful for paints or other liquid formulations where larger quantities of base materials are added and which can be added by weight and whereby precise measurements of the larger base materials is not particularly required. However, the incorporation of nutating pumps and the addition of smaller amounts of additives by volume using the nutating pumps enables precise dispensing of the additives, such as colorants for paint. The larger containers or reservoirs of base material may be disposed at a remote location from the dispensing apparatus.

Abstract: A paint colorant dispenser for dispensing colorants into both large and small containers includes a cabinet for accommodating a plurality of color and canisters in fluid communication with a common dispense outlet. A container shelf unit is disposed in front of the cabinet and below the dispense outlet. The shelf unit includes a horizontal base disposed below the dispense outlet upon which large containers can rest. The shelf unit also includes a pivoting shelf which can pivot upward and provide a horizontal resting surface closer to the dispense outlet for smaller containers. A controller, keyboard and monitor are contained in a second modular cabinet that can be disposed on either side of the first cabinet. An additional modular cabinet can be provided for accommodating additional colorant canisters. A drip containment system is disposed in the modular shelf unit.

Abstract: A method and an apparatus for multiple, simultaneous synthesis of compounds. The apparatus includes a reaction block having a heating layer, a cooling layer, each of which may perform both functions, and a collection sump. A plurality of reaction tubes are supported in the reaction block in a matrix. Each reaction tube has a top outlet, a bottom outlet and a filter above the bottom outlet. Spool valves are located to control the bottom outlets of the reaction tubes. Obturators are provided to close the top outlets of the reaction tubes and to provide venting for the reaction tubes. The collection sump alternately may be equipped with individual collection tubes for each reaction tube. Each reaction tube is formed with a restrictive waist and protrusions arranged in a pattern between the waist and its bottom outlet to improve the mixing of the resinous solid supports by creating turbulence.

Each reaction tube is formed with a restrictive waist and protrusions arranged in a pattern between the waist and its bottom outlet to improve the mixing of the resinous solid supports by creating turbulence. The restrictive waist limits the height of the vortex of solution during mixing and reaction to facilitate heating and refluxing.
