| 121 | Automatic sample preparation for analysis of sample particles | US279014 | 1988-12-02 | US5110553A | 1992-05-05 | Michael L. Ruschak; William D. McAninch; Dan A. Anderson |
| Apparatus for analyzing the compositions of metal particles. The apparatus includes a cup which, when filled to maximum capacity will hold substantially the same amount of metal particles each time it is filled, and has a profile that diverts any excess particles away from the cup. A vessel is provided for receiving the particles from the cup and for dissolving the particles when a solvent is sent to the vessel. A known amount of solvent is directed to the vessel to dissolve the particles and thereby provide a dissolved sample of metal for analysis. An optical emissions spectrometer receives the dissolved sample and is employed to produce emission spectra from the dissolved sample. The spectra is compared to emission spectra produced by a known amount of a known alloy of the same metal as the sample metal to determine the composition of the sample metal. | ||||||
| 122 | Coffee dispenser | US384629 | 1989-07-25 | US4998648A | 1991-03-12 | Orlando Contreras |
| A device for dispensing predetermined equal amounts of coffee into the reservoirs mounted to the upper termination of the lower detachable portion of an expresso coffee pot. The device is adapted to securely receive the open end of a cylindrical coffee container on one end and the other end has several concentric recesses that cooperatively receive the upper termination. A dispensing member with hemispheric shape is rotably mounted within the device to cover the opening of the smaller one of the concentric recesses with the convex side and capable of dispensing a predetermined amount of coffee when rotated with an externally accessible handle member. | ||||||
| 123 | Device for dispensing a predetermined quantity of a liquid | US269349 | 1988-11-10 | US4874114A | 1989-10-17 | Jean Guigan |
| A device for dispensing a predetermined quantity of a liquid comprises: a pipette (1) constituted by a rod having a substantially spherical open element at its end, the element having a calibrated internal volume; mechanical device for holding this pipette either in a first position (51) for filling and for calibration purposes, or else in a second position (52) for emptying purposes; and mechanical device for rotating the pipette at high speed. | ||||||
| 124 | Powder dosing apparatus | US269114 | 1988-11-09 | US4850259A | 1989-07-25 | James P. Morris |
| A powder dosing apparatus, especially for use in the priming of ammunition, comprises a tray containing a uniformly thick layer of powder and a dosing assembly arranged to extract a plurality of doses of powder from the tray. After extraction of the doses the assembly is moved to an adjacent station where it ejects the doses into respective receptacles, such as capshells. During ejection, the powder in the tray is replenished from a chute and the layer is raked and levelled by an assembly comprising a rake and doctor blades in readiness for a subsequent dose extraction step. | ||||||
| 125 | Device for supplying material with unit doses of parasiticidal composition | US349399 | 1982-02-16 | US4538744A | 1985-09-03 | Jorg Weissenborn |
| A device is provided for supplying material with unit doses of particulate parasiticidal composition, comprising, in combination:(1) a supply of particulate parasiticidal composition;(2) a feeder for feeding unit doses in regular sequence from the supply to the material;(3) a capacitive approach switch for sensing each unit dose as fed to the material;(4) a timer for timing the interval between unit doses; and(5) a signalling device for giving a signal when the interval between doses exceeds a predetermined limit. | ||||||
| 126 | Batch material blender and method therefor | US83005 | 1979-10-09 | US4307759A | 1981-12-29 | Vincent S. La Bianca |
| A measuring and transferring device for automatically metering predetermined and variable quantities of virgin plastic material, reprocessed plastic material and color concentrate to an extrusion machine. This masterbatch material blender incorporates a rotary conveyor having openings therein that receive and retain predetermined amounts of virgin plastic material and color concentrate in one position of movement of the conveyor and discharge same to the extruder in yet another position of movement thereof. Furthermore, such conveyor is adapted to control yet another reciprocable metering and transfer mechanism that similarly controls the addition of reprocessed material to the batch by way of the same measuring and transferring device. | ||||||
| 127 | Liquid metering wheel | US3552213D | 1969-06-03 | US3552213A | 1971-01-05 | AUCHAPT PIERRE; BRUN ANDRE |
| THE METERING WHEEL INCLUDES AN OPEN VESSEL WITH A PARTITION WALL WHICH DEFINES ON EACH SIDE TWO CHAMBERS EACH ASSOCIATED WITH A CONSTANT-LEVEL WEIR, A METERING DISC CARRIED BY A HOLLOW ROTARY SHAFT WHICH IS ROTATABLY MOUNTED IN LEAK-TIGHT MANNER WITHIN A BEARING CARRIED BY THE PARTITION WALL AND IMMERSED IN ONE OF THE CHAMBERS. THE METERING DISC IS FORMED BY A FLAT CYLINDER WHICH COMPRISES ON THE ONE HAND AN INTERNAL CAVITY HAVING A DEVELOPMENT OF 180* WITHIN THE INTERIOR OF THE DISC AND A VOLUME WHICH IS EQUAL TO THE FLOW TO BE METERED PER
COMPLETE REVOLUTION OF THE DISC AND A CONNECTING DUCT FOR PRODIVING A RADIAL COMMUNICATION BETWEEN SAID CAVITY AND THE HOLLOW SHAFT. THE DISC COMPRISES ON THE OTHER HAND A PORTION OF REDUCED THICKNESS OVER A DEVELOPMENT OF 180* WHICH IS COMPLEMENTARY TO THE DEVELOPMENT OF THE INTERNAL CAVITY, THE REDUCTION IN VOLUME OF THE DISC WITHIN SAID PORTION OF REDUCED THICKNESS BEING SUCH AS TO CORRESPOND TO ONE-HALF THE VOLUME OF SAID CAVITY. |
