Title: Vehicle track
Inventor: WELLMAN RONALD ALAN
IPC: B62D55/24
Filed: 2010-11-19
Granted: 2017-01-17
Abstract: The tracks of the present invention utilize cut pieces of reinforcement which are associated with each individual drive lug. By using individual pieces the lugs can be easily built up with multiple layers of rubber and reinforcement. Incorporation of such inner fabric reinforcement layers adds stiffness to the lugs and thereby increases the torque capacity of the track.  All embedded inner fabric reinforcement layers are made of individually cut pieces of fabric which do not extend continuously around the entire circumference of the track. In the circumferential direction the fabric layers typically both begin and end within the lug without extending into the carcass of the track. In one aspect, the invention is an endless vehicle track comprising a body formed of an elastomeric material having an outer surface displaying a series of ground engaging profiles longitudinally spaced along said surface and an inner surface displaying a series of longitudinally spaced drive lugs adapted to be engaged by drive sprockets on said vehicle for retaining said track on said vehicle and for driving said vehicle, said drive lugs having a given width and height, said drive lugs having embedded therein at least a first inner fabric reinforcement layer extending into the lugs to a distance inward from the outer surface, wherein the inner fabric reinforcement layer begin at a first point within the lugs and end at a second point within the lugs.

Title: Process for treating high paraffin diluted bitumen
Inventor: VAN DER MERWE SHAWN
IPC: C10G1/04
Filed: 2011-02-25
Granted: 2014-08-19
Abstract: A paraffinic solvent recovery process for treating high paraffin diluted bitumen includes supplying the latter to flashing apparatus; separating into flashed paraffinic solvent and diluted bitumen underflow; and returning a portion of the underflow as returned diluted bitumen into the high paraffin diluted bitumen prior to introduction into the flashing apparatus, at temperature and amount to shift asphaltene precipitation equilibrium to reduce asphaltene precipitation. The process includes pre-heating the high paraffin diluted bitumen by transferring heat from hot dry bitumen, flashed paraffinic solvent and/or a portion of diluted bitumen underflow. Flashed paraffinic solvent may contain residual light end bitumen contaminants that increase asphaltenes solubility and the process may include removing contaminants to produce reusable paraffinic solvent at given solvent-to-bitumen ratio range to maintain given asphaltene precipitation. The process may also include a bitumen fractionation column producing hot dry bitumen underflow containing at most 0.5 wt% paraffinic solvent.

Title: Haptic chair sound enhancing system with audiovisual display
Inventor: TAYLOR OH ELIZABETH ANN
IPC: A61F11/04
Filed: 2009-09-18
Granted: 2015-11-10
Abstract: A sound enhancing system includes a haptic chair formed of a chair and plural speakers mounted to the chair. The speakers receive audio input from a subject audio source and generate corresponding sound vibrations. The chair is configured to deliver the generated sound vibrations to various body parts of a user seated in the chair through the sense of touch and by bone conduction of sound. A visual display viewable by the user corresponds to the generated sound vibrations and is indicative of the corresponding audio input. The sound enhancing system enhances user experience of the audio input by any one or combination of visually, by the sense of touch, and by bone conduction of sound.

Abstract: Dispositif de surveillance de ligne de transport dénergie monté sur une ligne électrique, le dispositif comprenant un montage de circuits destiné à surveiller la ligne de transport dénergie et à communiquer des informations la concernant. Un point de référence à la masse du montage de circuits est relié électriquement à la ligne de transport dénergie. Le dispositif de surveillance, y compris son montage de circuits, est donc sensiblement au même potentiel que la ligne de transport dénergie, si bien quun champ électrique sensiblement égalisé ou uniforme enveloppe le dispositif. Le potentiel et le champ électrique sensiblement égaux permettent de réduire le bruit et les interférences affectant les communications avec le dispositif de surveillance par rapport à dautres dispositifs aux potentiels différents de ceux de leurs lignes de transport dénergie associées. Un coussinet de matériau semiconducteur peut être placé entre la ligne de transport dénergie et les conducteurs électriques dans le but de ralentir le taux de variation du potentiel du montage de circuits du dispositif lorsque celui-ci est monté sur la ligne de transport dénergie et de minimiser ainsi le risque de décharge par effet couronne.

Abstract: A soy protein product having a protein content of at least about 60 wt% (N x 6.25) d.b., preferably a soy protein isolate having a protein content of at least about 90 wt% (N x 6.25) d.b., is prepared from a soy protein source material by extraction of the soy protein source material with an aqueous calcium salt solution, preferably calcium chloride solution, to cause solu-bilization of soy protein from the protein source and to form an aqueous soy protein solution, separating the aqueous soy protein solution from residual soy protein source, concentrating the aqueous soy protein solution while maintaining the ionic strength sub-stantially constant by using a selective membrane technique, optionally diafiltering the concentrated soy protein solution, and dry-ing the concentrated and optionally diafiltered soy protein solution.  Alternatively, the concentrated and optionally diafiltered soy protein solution may be diluted into water to cause the formation of a precipitate, separating the precipitate from the diluting water (supernatant), and drying the separated soy protein solution to form a soy protein product having a protein content of at least about 60 wt% (N x 6.25) d.b., preferably a soy protein isolate having a protein content of at least about 90 wt% (N x 6.25) d.b..  The supernatant may be processed to form soy protein products having a protein content of at least about 60 wt% (N x 6.25) d.b., preferably a soy protein isolate having a protein content of at least 90 wt%  (N x 6.25) d.b. Alternatively, the precipitate from the dilution step and diluting water is acidified to resolubilize the precipitate and form a clear soy protein solution. The clear soy protein solution is concentrated while maintaining the ionic strength substantially constant by using a selective membrane technique followed by optional diafiltration and drying.

Granted: 2014-11-04
Abstract: A reversible gearbox features a first input gear mounted on for rotation about a first axis and a second input gear mounted for rotation about a second axis parallel to the first axis in a counter-rotational relationship with the first input gear. The input gears are arranged for selective coupling of either one thereof to a drive source rotatable in a predetermined direction, whereby at least one output gear is arranged within the gear train for driven rotation of the output gear in opposite directions depending on which of the first and second input gears is driven in the predetermined direction by the drive source. Accordingly, a unidirectional drive source can be used to drive the gearbox output in either direction by selecting from different input connections. The gearbox may be employed for an agricultural auger to be driven by the power take-off of a tractor.
