Title: Method of and system for video surveillance of a fast moving web
Inventor: SCHOENBORN GARY A
IPC: G01N21/89
Filed: 1997-10-16
Abstract: A method of and system for video surveillance of a fast moving web monitors a continuous web of material passing through a papermaking machine. A plurality of video cameras arranged on the back and front sides of the machine monitor the web at selected locations of interest along the papermaking path. Outputs from the cameras are applied to associated video tape recorders. Upon detection of a web break, the video recorders are stopped and then operated to play back the various images of the web that were recorded just prior to the break. Outputs from the video recorders are coupled through time base correctors to a plurality of a quads, with each quad receiving inputs from four video recorders. Each quad is connected to an associated video monitor and is selectively controlled so that the monitor either displays in quadrant fashion all four views from the associated video recorders or displays only a selected one of the views. The time base correctors eliminate jitter in the monitor displays that would result from the video recorder tapes being mechanically driven. A computer enables an operator to control the system with a graphical interface and utilizes a frame grabber that converts an analog output signal from a quad to a digital format that can be stored for later retrieval, manipulation and analysis.

Title: Forage compactor
Inventor: HUNTER DOUGLAS ANDREW
IPC: A01F15/08
Filed: 1997-12-11
Abstract: A forage compactor for compressing forage or crop into bales of increased crop density for transportation. A crop feed area feeds crop to a conveyor where it is moved to a scale area for proper bale weight. An indexer severs the crop while moving it from the scale area to the compression chamber. The crop is compressed and moved to a strapping chamber where straps are applied to the compressed crop. The bound bale is manipulated as desired at the product handling area downstream from the strapping chamber. The crop is provided with substantially constant stress during compression and moisture sensors in the strapping chamber sense the moisture content of the severed crop within the bale to be bound. The weight of the crop within the compression area may be reduced to reduce machine overloading. Keyway plungers provide reduced side loading on the main ram used for crop compression. The feed inlet area is located on the same side of the compression chamber as the exit chamber to allow for more efficient operation and area utilisation.

Inventor: WEBER TORY
IPC: B62B1/18
Filed: 1998-05-04
Abstract: In an effort to facilitate the dumping of a load from a wheelbarrow the present invention provides pivoting hand grips attached to the ends of wheelbarrow handles, which enable an individual handling a wheelbarrow to maintain a constant grip on the handle while dumping. Moreover, the pivoting hand grips enable the arms of the individual to be consistently in a position of strength proximate his hips. The risk of injury, particularly back injury, is minimized by eliminating the arm extension required to dump a standard wheelbarrow. The awkward and strenuous exercise of dumping a wheelbarrow is thereby replaced by a smooth flowing action. The present invention also includes a locking mechanism for preventing the hand grips from rotating during normal stationary or traveling usage and a releasing mechanism which can be easily manipulated by the fingers of the handler while gripping the hand grips when the load is being dumped.

IPC: H04L69/40
Filed: 1997-11-12
Abstract: Method for restoring the communication to a normal one when one unit network has a defect in a communication network system which is constituted of a plurality of unit networks. Unit networks are connected with internetwork connection circuits. Usually, communication is done in each unit network via a communication path which is formed by looping back remote communication devices at both ends of the unit network. When a defect such as the cut of a communication line occurs in a certain unit network, the loopback of the remote communication devices at both ends of the unit network which has the defect is canceled for the internetwork connection circuits and then an alternate communication path is formed. Using the alternate communication path, communication is done between local communication terminals which are adjacent to the defective point.
