Abstract: A centering and loading apparatus for locating the center of a fill opening of a vehicle and loading bulk material into the vehicle through the opening is provided which includes a movable loading spout assembly and a locator assembly which locates the fill opening of the vehicle and is adapted to move the loading spout assembly for centering over the fill opening of the vehicle. The loading spout assembly is supported on a first support and is adapted to move along the longitudinal and lateral horizontal axes of the first support for aligning the loading spout assembly over the fill opening of the vehicle. The locator assembly includes a pair of scanning devices, for example, charge coupled devices, radio frequency sensors, and laser and infrared devices, that detect and scan the fill opening to locate the center of the opening. The locator assembly and loading spout are controlled by a programmable logic controller, which processes the data provided by the scanning devices to calculate the center of the opening. Once the center of the opening is calculated, the controller moves and centers the loading spout assembly over the opening and starts the loading sequence. A  centering and loading method includes scanning the vehicle with scanning device, which preferably detects reflected light, locating the center of the fill opening from the signals generated by the scanning device, and aligning a loading spout with the center coordinates of the opening so that the vehicle can be loaded with the bulk material by the loading spout through the fill opening.

Title: Modular electrical system
Inventor: MAY LINDY LAWRENCE
IPC: H01R25/00
Filed: 1996-08-22
Granted: 2009-07-07
Abstract: An electrical system including modular components which quickly assemble to create common lighting and general utility electrical circuits. All wiring is completed in the electrical box prior to installing the electrical devices such as switches (2) and receptacles (4), thereby eliminating the need for extra length wires in the electrical boxes and the cumbersome wiring practices associated with conventional residential electrical circuits. The electrical devices plug into the prewired electrical box, thereby providing quick and easy removal and replacement of the device in the event of failure. The common residential ligthing and general utility circuits are automatically configured by simply selecting the proper electrical components. A dedicated earth ground is automatically carried to each electrical component with no effort on the part of the installer, thereby providing safer electrical circuits. The electrical system provides multi-conductor cables (17-19) which have cable sheathes extruded to a specific exterior profile to insure proper connection with the electrical boxes thereby assuring proper configuration of the electrical circuits. The electrical system also eliminates the need for wire nuts.

IPC: A01B49/02
Filed: 1998-06-25
Granted: 2001-09-11
Abstract: A flexible frame structure for an implement includes a wing frame section with several fore-and-aft spaced, transversely extending rank tubes that are connected to surrounding support structure with conventional, non-resilient pin joints for rotation about a fore-and-aft extending horizontal rank axis. A transversely extending rear rank tube is rigidly connected to a fore-and-aft extending caster wheel support frame which extends forwardly above the ends of the rank tubes. A caster wheel projects forwardly from the end of the support frame out of interfering relationship with the forward tool-carrying rank. The rear rank tube and caster wheel support frame define a rigid L-shaped member which is connected to the adjacent frame section by a conventional pin and pivot structure for rotation about a first axis corresponding to the rank axis, and a second axis perpendicular to the forward direction. A diagonal brace has a leading end pivotally connected to the surrounding support structure and a trailing outer end connected near the vertex area of the L-shaped member for pivoting about a transverse axis. The non-resilient pin joints connect the outer ends of the rank tubes to the underside of the fore-and-aft leg of the L-shaped member, and pin hole clearances allow the frame section to distort for the implement flexibility, without rotation of the rank tubes, when operating on irregular ground surfaces. Centrally located fore-and-aft links are connected between the ranks for further rank rotational resistance.

Granted: 2002-04-16
Abstract: The present invention relates to a method of forming a layup of wood veneer sheets and an apparatus suited for implementing said method. In the method, each of the sheets (1) is first taken separately into a forward-feed position on a level situated above the layup (2). Next, the sheet is lowered with its tailing edge first onto an intermediate platform located above the desired laying point in the layup, and further therefrom, the sheet is lowered with its leading edge first onto the layup. The apparatus includes a conveyor (6) arranged to run as an endless loop. The conveyor is adapted to perform a continuous loop travel during the entire cycle of the sheet-laying sequence. The conveyor bars supporting the sheet are omitted from a given section of the conveyor loop thus facilitating a stepwise lowering of the sheet onto said intermediate platform, and therefrom, further onto the layup. The alignment of the sheet is accomplished by means of a tailing edge stop (4).

Title: Triple tube scoop lighting fixture
Inventor: MIER-LANGNER ALEJANDRO
IPC: F21V17/06
Filed: 1998-09-11
Granted: 2007-06-05
Abstract: A lighting fixture or luminaire optimizes the performance of a multi-tube fluorescent lamp by orienting the lamp in a horizontal position while focusing the omnidirectional output from the lamp. A novel swivel assembly enables the lamp to move as a single unit with the reflector housing, thereby to maintain the alignment of the lamp tube to the reflector surface while allowing aiming of the light beam. In one embodiment of the invention, a socket housing snap fits into the reflector housing so that the lamp rotates simultaneously with the reflector housing. The beam spread delivered by the luminaire has a bright center and a soft perimeter so that the bright center may be used as accent lighting and the peripheral light may be used for soft general lighting.

Abstract: A cutter element that balances maximum gage-keeping capabilities with minimal tensile stress induced damage to cutter elements is disclosed. The cutter elements (150) of the present invention have a non-symmetrical shape and may include a more aggressive cutting profile than conventional cutter elements. In one embodiment, a cutter element is configured such that the inside angle at which its leading face (114) intersects the wear face (112) is less than the inside angle at which is trailing face (118) intersects the wear face (112). This can also be accomplished by providing the cutter element (160) with a relieved wear face (162). In another embodiment of the invention, the surfaces of the present cutter element (500) are curvilinear and the transitions between the leading (514) and trailing (518) faces and the gage face are rounded or contoured. In this embodiment, the leading transition is made sharper than the trailing transition.

Abstract: There is disclosed a method and apparatus for estimating the timing position of data bursts received in a data stream, where each data burst includes a number of bits comprising a training sequence in a fixed location.   The receiver includes circuitry for, in respect of each received data burst, estimating at least one position of the timing location of the training sequence, equalising the data burst for each estimated position, and correlating each equalised data burst. Where a plurality of positions of the timing location of the training sequence are estimated, the receiver circuitry, for each received data burst, determines the correlation result having the highest value and retains the equalised data burst associated with the correlation result having the highest value.
