Abstract: An improved pile-type, fin weatherstrip includes an elongated V- or U-shaped barrier fin bonded to a base strip and located between a pair of upstanding pile fiber arrays. The barrier fin is formed of thermoplastic film which is preferably smooth, but which may be roughened, dimpled or otherwise provided with a large number of pockets, or which may have a flocked surface. A lubricant grease is provided in the channel shaped cavity of the barrier fin, which lubricant is progressively dispensed in response to a wiping action type of movement which occurs when the barrier fin is compressed by the pile arrays during usage. The lubricant grease is exuded progressively over the useful life of the weatherstrip toward the free edges of the barrier fin located at or near the forward projecting face of the weatherstrip where such grease is dispensed in small amounts to decrease breakaway force, lower sliding friction and improved air infiltration characteristics. The barrier fin may be perforated so that lubricant grease is also forced into the fibers of the pile arrays where it will also work to the surface of the weatherstrip and improve the aforementioned properties.

Filed: 1990-05-23
Granted: 1995-04-11
Abstract: A method for manufacturing a coated optical fiber includes depositing aconductive coating on the optical fiber and measuring a value of conductance of that coating. Featured within the manufacturing method is a method for measuring the thickness of the conductive coating on an insulator, e.g., carbon on an optical fiber, including the following steps. An electromagnetic field is established by an input signal. The conductively coated insulator is moved through the energized electromagnetic field. The conductive coating on the insulator is oriented with respect to the electric field so that their interaction increases transmission loss from input to output. An output signal is extracted from the electromagnetic field. From changes in the output signal with respect to a predetermined standard, or reference, the conductance and the thickness of the conductive coating are determined. From the measured thickness of the coating, a control signal is generated for dynamically controlling one or more of the process parameters for depositing the coating on the insulator from a precursor gas. The coated insulator continuously moves through the apparatus without any physical contact. No interruption of the production process occurs.

Abstract: A process is described for making a laminated wood product having improved strength and dimensional stability (i.e., less warping caused by temperature and/or moisture change in drying, transportation and in use). Adjacent surfaces of lumber or veneer laminae cut from a single piece of wood are arranged in units of three laminae where the center lamina is twice the thickness of each outside lamina and in such a way that the outer laminae are rotated 180 degrees about their longitudinal axes to provide mirror images of the surfaces of the center lamina. These trios are arranged in a symmetrical manner about the central plane of the laminate and then bonded together. The minimum number of laminae is three, but with increments of three additional laminae the mirror-laminate can be built up to any desirable thickness. The mirror-laminate may be used in rough form or surfaced to specific finished dimensions. It is an improved value-added product which is stronger than a solid piece of wood of similar quality and size.
