| 6003439 | Microflake glitter fabrication A metallic flake manufacturing device uses a bearing to form the flakes. The bearing is located within a container which receives a fluid having suspended metallic particles. The bearing has an outer race, an inner race, and a plurality of bearings dispos... | 12/21/1999 |
| 5253993 | Apparatus for the production of pellets of metal powder used as catalysts An apparatus for the production of pellets of metal powder, more particularly pellets of highly active metal powder, for example Raney catalysts, has a press with a filling shoe and a pellet discharge shoot. A wet processing environment is established and... | 10/19/1993 |
| 5103720 | Separating apparatus An apparatus for separating of flowable and non-flowable constituents mixed with each other, particularly for the purpose of preparation of foodstuffs, operates with an elastic presser belt which is held pressed against the circumferential surface of a se... | 04/14/1992 |
| 5073200 | Low pressure system for extraction of soluble matter from fibrous material An improved system for extracting soluble substances from fibrous material by using a plurality of maceration and compression steps thereby excerting moderate pressure on the fibrous material up to 15 bars. Arrangements are made to saturate the fibrous materia... | 12/17/1991 |
| 4757757 | Compaction of granular solids with a combination of shear and direct compression A first body has a cylindrical section that is adjacent a conical section so as to form a constricted passage through which granular solids are forced under pressure. Passage through the constriction results in the application of shear forces to the granu... | 07/19/1988 |
| 4643088 | Method and device for extracting juice from fruit A dual-cycle method of extracting juice from fruit and a juice extraction installation consisting of two angular presses in tandem arrangement in which the fruit mash yields first quality juice and pomace in the first press, and this pomace is immediately... | 02/17/1987 |
| 4524139 | Process for the compressive regeneration of flexible, porous materials This invention relates to a process and apparatus for the compressive regeneration of flexible, porous materials used as filter particles, oil-separating particles or carrier particles in a reactor. These materials are loaded in a reactor with a liquid co... | 06/18/1985 |
| 4363264 | Counter current diffusion extractor A counter current extractor in which material to be extracted is caused to move in counter current with an extracting liquid by a screw conveyor characterized in that the direction of rotation of the screw conveyor is intermittently reversed. A process fo... | 12/14/1982 |
| 4323007 | Method of extraction of juice from fruit A method of extracting clear juice from apples and similar fruit involving the use of a screw press having a feed screw with a very gradual continuous slope of the body of the feed screw such that the fruit is gently compressed as it passes through the sc... | 04/06/1982 |
| 4187667 | Collection and recycling apparatus for crop particles in a roll forming machine Apparatus in a crop roll forming machine for collecting particles of crop material lost from either the crop package or loose crop material during the roll formation process consisting of a collection pan, a horizontal collecting auger, an elevated delive... | 02/12/1980 |
| 4116760 | Method and apparatus for removing liquid from a slurry of solid material A method of removing liquid from a slurry of solid material in liquid in which the liquid is squeezed from the slurry by passing the slurry through a roll nip and, simultaneously with the squeezing and passing, the liquid squeezed from the slurry is block... | 09/26/1978 |
