| 4046682 | Toner reclaiming system Toner particles which are removed from a photoconductive drum are trapped by a moving filter at a toner collection station and on movement of the filter to a toner discharge station, the toner is discharged into a toner reservoir. The filter may be of suc... | 09/06/1977 |
| 4042511 | Low profile static screen Apparatus for separating or classifying the contents of a flowing slurry comprising a descending flow surface having a low profile and associated therewith a relatively low head box, the latter of which is distinguished by a relatively restricted cross se... | 08/16/1977 |
| 4040948 | Device for cleaning flock formed by natural fibers, especially cotton flock, of dirt particles This disclosure relates to apparatus for cleaning natural fibers of their contaminants by passing the same through a pair of rotary drum sieves each having a porous peripheral surface subject to a vacuum whereby natural fibers adhere to the porous periphe... | 08/09/1977 |
| 4000061 | Particulate dry product loading apparatus An enclosed particular dry product is conveyed through a conduit by a gaseous fluid formed by a vacuum blower. Metered hoppers feed the product into the conduit. A cyclone removes the product from the fluid and conveys the same to a separating screen. The... | 12/28/1976 |
| 3997435 | Method for selecting hollow microspheres for use in laser fusion targets Hollow microspheres having thin and very uniform wall thickness are useful as containers for the deuterium and tritium gas mixture used as a fuel in laser fusion targets. Hollow microspheres are commercially available; however, in commercial lots only a v... | 12/14/1976 |
| 3997434 | Concrete reclamation system A no-discharge concrete reclamation system that eliminates all waste products and associated pollution. In addition to separating and washing sand and aggregate as provided in conventional systems, the invention provides for holding the water-cement slurr... | 12/14/1976 |
| 3996015 | Catalytic reactor with dirt trap An apparatus for contacting a fluid stream with a bed of catalyst wherein solid particulate matter is removed from the fluid stream before contact with the catalyst bed.
