Title: Procede pour encapsuler une plaque isolante en fibres de verre
Inventor: KNAPP KENNETH D
IPC: E04B1/76
Filed: 1996-08-21
Granted: 2005-05-17
Abstract: On encapsule une plaque isolante en fibres de verre, en utilisant un matériau d'encapsulation ou d'enveloppement (152) qui est appliqué sur la surface supérieure d'une plaque ou noyau (11) en fibres de verre, ledit matériau d'enveloppement s'étendant contre les surfaces latérales. La largeur du matériau d'enveloppe est supérieure à la somme des largeurs de la surface supérieure et des deux surfaces latérales, si bien que les bords dudit matériau d'enveloppement, lorsqu'il est en place, s'étendent au-delà du noyau en fibres minérales. L'application de vide sous le noyau en fibres minérales par une conduite de mise sous vide (186) tire le matériau d'enveloppement au-delà des surfaces latérales situées sous le noyau.

Title: Wind-resistant shingle and method of applying
Inventor: STAHL KERMIT E
IPC: E04D1/26
Filed: 1998-05-22
Granted: 2006-10-10
Abstract: A shingle and a method of applying the same to a roof is disclosed, in which the shingles are wind-resistant, opposing being torn from a roof by wind or the like. The shingles each include a pair of vertically spaced-apart lines extending horizontally across the lower ends of butt portions of the shingles, with at least a lower-most line being a line of sealant, and defining between the vertically spaced-apart lines a fastener zone, which fastener zone may have fastening spots therein that, in turn, may define a fastening line. When shingles in accordance with this invention are applied to a roof, the line of adhesive connection between tab portions of shingles in an overlying course are secured to lower ends of butt portions of the shingles of a subjacent course, sufficiently low below the tab portions of shingles, as to preclude any significant engagement by wind or the like that may tend to lift the tab portion off the sealant line. Additionally, the person applying shingles to a roof is directed where to apply the fasteners, so that a greater number of fasteners secure a given shingle to the roof.

Abstract: The plant pot has a bottom surface with a plurality of drainage holes therethrough, and the saucer has a plurality of radially spaced-apart upward projections therefrom to engage selected ones of the drainage holes. The bottom surface of the plant pot has a raised central portion having an inner diameter corresponding approximately to the diameter of an imaginary circle defined by radially outermost points of the upward projections from the saucer, thereby facilitating axial alignment of the saucer relative to the plant pot. The upward projections have radially outwardly extending flanges adjacent distal ends thereof, the flanges being configured so as to extend slightly above and slightly radially outwardly from the selected ones of the drainage holes when installed, so as to provide snap-on securing of the saucer to the plant pot. Preferably, the saucer has a plurality of radially spaced-apart recesses extending upwardly from its bottom surface, positioned to accommodate the upward projections of another identical saucer when the saucers are stacked together. This significantly reduces the height of a stack of saucers, for easier and more economical shipping and handling.

Title: Laser oscillator system
Inventor: MATSUO KAZUHIDE
IPC: H01S3/02
Filed: 1998-07-06
Granted: 2001-07-17
Abstract: The heat generated by a laser oscillator is partly radiated toward a frame.  The radiated heat is partly absorbed by a cooling mechanism.  The remaining heat is transferred through a chamber which dissipates part of the heat, to a heat insulating panel, which blocks most of the heat.  The heat generated by the laser oscillator is partly radiated outwardly and reflected by a casing inwardly toward the frame.  The reflected heat is partly absorbed by cooling mechanisms.  The remaining heat is transferred through chambers which dissipate part of the heat, to the heat insulating panel, which blocks most of the heat.  Therefore, any temperature rise of the frame due to the heat generated by the laser oscillator is very small, and the frame is prevented from being deformed due to the heat from the laser oscillator.  Because the frame is not deformed, a laser beam emitted from the laser oscillator is applied to a desired position which remains unchanged.

Abstract: An oxygen sensor is disposed behind an exhaust gas purifying catalyst for an internal combustion engine and which suppresses the influence of unburnt hydrocarbon on the output voltage. A sensor element 1 is provided with a detection electrode 4 on the outer face of a zirconia ceramic body 2, a reference electrode 3 on the inner face of the ceramic body 2 and a spinel protective layer 5 on the outer surface of the detection electrode 4. The tip end of the sensor element 1 is covered with a protective cover 10 which is provided with an outer partition wall 11 having through holes 11a and an inner partition wall 12 having through holes 12a.      In a case where the pressure difference between the inside and outside of the protective cover 10 is .DELTA.P(atm) when the atmospheric air with a volume flow rate Q(1/min) is passed into the protective cover 10 from the outside, the ratio .DELTA.P/Q2 is 3.2×10 -5(atm.cndot.min2.cndot.1 -2).  When the surface temperature of the sensor element 1 is changed in a range of sensor active temperature, the reversing time is substantially constant. Therefore, the catalyst deterioration can be detected by the oxygen sensor with high accuracy.

Abstract: Decoder circuitry, and an associated method, decodes an encoded signal received at a receiver. A determination is made of the levels of distortion introduced upon a signal during its transmission to a receiver upon a nonideal communication channel. If the communication channel introduces moderate amounts of distortion upon the signal, a complex decoding technique such as a standard trellis decoding technique is utilized to decode the signal. If the channel is determined to introduce only small levels of distortion upon the signal, a relatively simple, decoding technique is instead utilized.

Abstract: There is disclosed a workhead for timber processing, the workhead having a main body and a jaw assembly for grappling timber. The jaw assembly includes first and second cooperating pairs of jaw arms that are pivotally mounted to the main body. The first of the cooperating pairs of jaw arms provides cutting blades for delimbing. The workhead further includes a feed roller assembly for translating a felled tree through the cutting blades. First and second feed rollers of the feed roller assembly are associated with the jaw arms of the second cooperating pair of arms of the jaw assembly. A third feed roller is provided on the main body for pivotal movement relative to the main body. The feed rollers also effect compression debarking of the felled tree as it is translated through the cutting blades. Each roller has projecting engaging bars which extend in a generally helical configuration along the outer surface of the roller and between its opposed terminal ends. Each of the engaging bars is spaced apart from an adjacent engaging bar in a substantially parallel relationship, and the engaging bar has a contacting edge to engage the surface of the tree, with the contacting edge providing blunt longitudinally extending projections along its length. Also disclosed is a fluid delivery system having-a swivel hydraulic manifold in combination with a fixed hydraulic manifold attached to the main body of the workhead. The workhead is capable of various timber processing operations, such as felling, grappling, bunching, shovel-logging, loading, debarking, delimbing and bucking.
