Abstract: An apparatus is provided herein for separating a light liquid (e.g., grease) from a heavy liquid (e.g., water] in a mixture of such liquids. The apparatus is provided with enhanced gravitational separation of such liquids. The apparatus includes a separation chamber for receiving the mixture of liquids, the separation chamber being defined by a plurality of walls and a separation chamber bottom. The separation chamber includes an inlet section, the inlet section comprising an inlet port for introducing the mixture of liquids into the separation chamber. The apparatus includes a level control for maintaining a pre-selected fluid level of the mixture in the separating chamber. The apparatus includes a discharge section, the discharge section comprising a first exit port for removing the light liquid from the separation chamber, the first exit port being positioned near the top of a wall of the chamber. The first exit port comprises a slat. An enclosure, which is connected to the outside of the apparatus, encloses the slot, the enclosure being connected to a second conduit through which the light liquid is discharged. The apparatus includes a downstream section, the downstream section comprising a second exit port in a downstream section of the separation chamber for removing the heavy liquid from the separation chamber.

Title: System and method for using circular constellations with uncoded modulation
Inventor: BETTS WILLIAM L
IPC: H04L27/34
Filed: 1998-03-04
Abstract: A system (Fig. 3) and method for communicating information using circular multidimensional signal space constellations (Fig. 1b) using uncoded modulation allows increased data rate and bandwidth by eliminating trellis encoding, thus reducing the number of computational cycles required for coding. Furthermore, the use of circular signal space constellations (Fig. 1b) lowers the transmit peak factor, thus consuming less power. Using uncoded modulations with circular constellations allows an approximate 10-20 % performance improvement for a given central processor unit. Additionally, circular constellations (Fig. 1b) allow the easy and reliable transmission of special marker symbols such as "End of File", "Start of Message", "End of Transmission" or "Increase or Decrease Data Rate".

Title: Lower steering arm assembly for an attaching device of a tractor
Inventor: SAYER JOHN
IPC: A01B59/06
Filed: 1999-10-22
Abstract: The invention relates to an assembly with a lower steering arm having a strut 1 and an attaching end 16. To achieve a cost-effective design while at the same time reducing the play between the attaching end 16 and the end of the strut 1 received therein, the attaching end 16 consists of a base member 18 and a cover 19. In the base member 18, there is supported the blocking pawl 34. The cover 19 is welded to the base member 18 and comprises a stop face 30 for the end face 10 of the strut 1, so that any tolerances in the region of the base member 18 provided in the form of a forging do not affect the position of the stop face 30. The latter can be aligned when connecting the base member 18 and the cover 19.      Because of its setting contour, the actuating lever 43 can be used for both the right-hand and the left-hand lower steering arm.

Filed: 1998-08-05
Abstract: L'invention concerne un site d'injection sans aiguille comportant un logement (16) définissant un passage (56) de fluide. On place à l'intérieur du logement (16) un élément (58) de joint à refermeture qui comporte un orifice (80) pouvant être ouvert ou fermé, et un réservoir (100) expansible et décompressible. L'élément de joint (58) à refermeture se trouve normalement dans une première position dans le logement, l'orifice (80) étant fermé et le réservoir (100) affaissé. L'élément de joint (58) à refermeture est déformable, de sorte qu'une pression de compression permet de lui faire prendre une deuxième position, dilatant le réservoir (100), ouvrant l'orifice (80) et faisant communiquer celui-ci (80) avec le passage (56) de fluide et le réservoir. Le retrait de la pression de compression facilite le retour de l'élément de joint à refermeture dans sa première position, provoquant la fermeture de l'orifice (80) et la décompression du réservoir (100). La décompression du réservoir (100) permet d'empêcher la formation de vide dans le passage (56) de fluide lorsque l'élément de joint (58) à refermeture retourne à la première position.
