Title: Apparatus and method of detecting loss of cross-sectional area of magnetic metallic strength members used in conductors such as aluminum conductor steel reinforced ("acsr") conductors
Inventor: BOOKER JAMES R
IPC: G01N27/82
Filed: 1997-04-24
Abstract: A method and apparatus for detecting a loss in cross-sectional area of metallic reinforcing members having magnetic properties of a conductor indicating corrosion effects on the conductor. The method and apparatus comprises a tug component to provide the motive force to move a data collection component and a detector component along a length of conductor. The tug component further includes a rechargeable battery, a motor energizable by the rechargeable battery, a guide wheel and tensioner assembly. Linked to the tug is a data collection component. In turn, a detector is linked to the data collection unit. The tug, data collection unit and detector all ride along the same conductor by a series of guide wheels and tensioners. The detector further includes a magnetic source spaced apart from an electronic coil winding. In use, a conductor is interpositioned between the magnetic source and electronic coil winding. The magnetic source is preferably energized to produce an alternating (e. g., oscillating or rotating) magnetic field which is directed at the conductor.        The amount of magnetic field passing through the conductor corresponds to the cross-sectional area of the steel reinforcing strands of a conductor.        The magnetic field recognized by the coil induces a varying voltage depending upon the cross-sectional area of the steel strands of the conductor through which the rotating magnetic field passes. The electronic coil may also be linked to a recording system such that the change in magnetic field induces a change in voltage in the coil which can be recorded on a strip chart, graph, CPU or other suitable data collection unit. The data collection component therefore may also include a relay system comprising a transmitter and received sufficient to send data streams and information to a ground surface when the unit is used above ground to analyze and test overhead conductors. An optional amplifier, band pass filter and maximum and minimum type voltage meter may also be included.

Title: Crop harvester platform having a reversible drive for the reel, cutterbar, center-feed augers and conditioner rolls
Inventor: KELLER MELVIN WILLIAM
IPC: A01D41/14
Filed: 1997-05-06
Abstract: A self propelled windrower is provided with a platform including a reel which sweeps crop to be cut over a sickle cutterbar and into the nip of a pair of counter-rotating center-feed augers that, in turn, deliver the crop to the nip of a pair of counter-rotating conditioner rolls; and these driven components may be reversed to disgorge slugs of crop. The reversible drive includes a hydraulic pump carried by the traction unit and coupled to a motor carried by the platform. The hydraulic motor on the platform is coupled to power a main gear box which distributes power to the driven components of the platform. Operation of the pump is electro-hydraulically controlled with a single switch being operable to effect forward operation of the platform drive train, and with a second switch being designed to be moved and held in place to effect and maintain the drive train in reverse. Both switches cannot be operated at the same time, however the machine can be reversed with the platform lowered, fully raised, or anywhere in between.

Title: Films pouvant etre pourvus de cavites par moulage

IPC: H05K1/03
Filed: 1996-06-07
Abstract: On décrit un film de résine, mince, thermodurcissable, que l'on peut soumettre à une procédure de moulage consistant à imprimer en creux sur ce film un motif de circuit imprimé à rainures, avec une perte minimum de précision du motif à rainures, lequel, ainsi que le rainurage, peuvent être durcis afin de produire un film de résine thermodurci que l'on peut utiliser pour produire éventuellement une plaquette imprimée. On peut donner une forme à ce film thermodurcissable, sans qu'il soit nécessaire de limiter l'écoulement au niveau des bords de celui-ci. La résine n'est pas conductrice et ce film est suffisamment uniforme dans son épaisseur pour qu'il soit possible de le mettre en forme thermiquement de façon homogène sur toute sa largeur. Ce film est peu fluide sur une grande plage de températures, de sorte que l'on peut contrôler son écoulement lorsqu'on le soumet à des conditions de durcissement. Ce film se transforme en gel ou présente des propriétés similaires à celles d'un gel, lorsqu'on le soumet aux conditions propices à son durcissement, et il répond ainsi aux exigences requises sur le plan commercial.

IPC: B01D39/18
Filed: 1997-12-10
Abstract: A filter element useful for filtering intake air for internal combustion enginesincludes a first filter media separated by an air space from a second filter media. The second filter media has a greater air permeability than the first filter media, but is electrostically charged. As a result of this arrangement, the capacity of the filter element is enhanced because large particles are trapped by the first filter media and smaller particles are trapped by the second filter media. As a result, the filter element has a longer life because, for a given contaminant condition of an air stream, unacceptable clogging of the filter element takes longer.
