20090293911 | COLLECTION MEANS FOR A MOBILE VACUUM APPARATUS FOR THE COLLECTION OF LIQUID OR SEMI-LIQUID MATERIALS - The apparatus comprises a front-mounted collection means for a vacuum tank for the collection of liquid or semi-liquid materials. The collection means comprises a substantially V-shaped housing with a scraper at the bottom thereof, a height adjustable suction inlet at the apex thereof, and a pair of laterally adjustable pivoting wings for varying its width to correspond to that of an alley or gutter. A plurality of rotary feeders, each having a vertical axis of rotation, are mounted to the housing adjacent the scraper to prevent accumulation of the materials on the scraper. The feeders do not contact either the surface upon which the scraper is operated, nor the scraper itself, but serve to mix thick consistency materials with thinner consistency materials and also to dislodge any accumulation that does occur. | 12-03-2009 |
20100019072 | LAND APPLICATION VEHICLE, LOADING APPARATUS AND MATERIAL HANDLING SYSTEM AND METHOD FOR SEMI-SOLID MATERIAL - According to an aspect of the invention, there is provided a land application vehicle for a semi-solid material, such as bio-solids. The vehicle includes a hopper and a distributor. The distributor includes a housing having a distributor inlet and at least one distributor outlet, a first distributor auger in the housing configured for transferring semi-solid material away from the distributor inlet towards the at least one distributor outlet and a second distributor auger in the housing configured for transferring semi-solid material back towards the distributor inlet. This creates re-circulation of the semi-solid material within the distributor, which inhibits packing of the semi-solid material at the ends of the distributor and generally aids in uniform distribution of the material. | 01-28-2010 |

20150322583 | Devices, Systems and Methods for Coating Surfaces - The present disclosure provides devices, systems and methods with applicability in the coating of surfaces, in particular three-dimensional surfaces, via anodization reactions. For example, the disclosed devices, systems and methods find use in the formation of microstructured or nanostructured layers, e.g., metal oxide microstructured or nanostructured layers, via anodization on a variety of devices including, e.g., medical devices. Devices modified with one or more microstructured or nanostructured layers are also provided. | 11-12-2015 |

20120224982 | Pump for Immersion Within a Fluid Reservoir - A pump for immersion in a fluid reservoir, such as a pit or lagoon containing liquid manure, from a position at an edge of the reservoir. The pump may be adapted for connection to a farm vehicle, such as a tractor, positioned at the edge of the reservoir. The pump comprises an extensible body, fluid conduit and drive means in order that a length of the pump may be varied in order to accommodate a variety of reservoir fluid heights. In addition, the pump may be pivotable relative to at least a portion of a frame in order that the entrance angle may be adjusted. The pump comprises a bottom housing with a bottom inlet and at least two tangential fluid outlets that are upwardly angled towards the conduit. A combiner is provided to merge the outlets with the fluid conduit. An impeller within the housing is shaped to transfer fluid tangentially and upwardly within the housing to co-operate with the upward angle of the outlets. These features reduce fluid pressure loss and thereby increase fluid flow rate through the pump for a given input power. | 09-06-2012 |

20140336954 | Calculating Fatigue and Fatigue Failure of Structures - The durability performance of a structure is virtually predicted, enabling the optimization of the durability performance. In a first act, the structure is modeled by a series of calculation points. Then, for each point, the stresses and strains brought by load cycles and defining hysteresis branches are determined. Then, an accumulated damage due to the load cycles is predicted and stored. For the prediction, first, using a hysteresis operator, a change in the stress along a portion of a hysteresis branch is calculated as a function of a change in the load in time, and, second, using the change in the stress and the stored accumulated damage, a change in the damage is calculated. Hence, also a change in the properties, including the stiffness, of the structure is calculated. Then, a further change in the stresses and strains is calculated on the basis of the change in these properties to determine a new adapted hysteresis branch. Then, a further change in the stress along a further portion of the adapted hysteresis branch is calculated as a function of a further change in the load in time. At the end of the process, the structure is manufactured accordingly. | 11-13-2014 |
