Abstract: A vapor recovery system used with fuel dispensers and having error detection capabilities incorporated therein for detecting vapor leaks and performance deficiencies in the vapor recovery system. The vapor recovery system includes a fuel nozzle connected to a fuel source for pumping fuel into a vehicle. A vapor transfer line is connected to the nozzle and has a connected pump which pumps fuel vapor from the nozzle through the vapor transfer line and into a vapor holding tank. A pair of test valves are connected in the vapor transfer line on opposite sides of the pump and are used to isolate selected sections of the vapor recovery system for test purposes. Connected between each test valve and pump is a pressure sensor for measuring pressure in the vapor transfer line. A digital processor is connected to the vapor recovery system to control the vapor recovery system and to place the vapor recovery system in various test modes.

Abstract: A template system is provided for laying out the location of telecommunication switching cabinets in a switching center. The template system includes a plurality of fixture templates and a plurality of connector pieces for joining the fixture templates to one another. Each fixture template includes pre-formed marking holes and pre-formed marking slots to mark the layout of the cabinet. The marking holes are used to mark the location of mounting holes in the floor. Marking slots are used to mark the location of access openings for wiring in suspended floor systems. The connector pieces interlock with the fixture templates so that the fixture templates are always spaced a predetermined distance from one another. The interlocking fixture templates and connector pieces minimize the reliance on measurements thereby reducing the number of errors likely to occur when laying out the cabinets.

Abstract: The invention relates to a method for making a dimensionally stable wood-thermoplastic composite material composed of a wood component and a thermoplastic component comprising the steps of forming a wood-thermoplastic mass at a temperature above the melting temperature of the thermoplastic component. The mass is then passed through a converging die to form a shaped extrudate profile having a cross sectional shape wherein at least a part of the converging die is maintained at a substantially higher temperature than that of the mass. The profile is then fed through a low friction thermally insulating land section, the land section having the substantially the same cross sectional shape as the exit end of the converging die. The profile is then quenched in a non-oxidizing environment to form a substantially dimensionally stable outer shell around the profile, the shell having a temperature below the melting temperature of the thermoplastic component.

Abstract: The present invention relates to a process for wet washing wool fabric and woolen articles. The process permits wet washing of articles such as aircraft seat covers while substantially eliminating shrinkage and preserving the fire retardant characteristics of the seat covers. The process includes washing the articles in an aqueous solution using a bi-directional intermittent wash cycle. The wash cycle includes agitating in a first direction for about two minutes, pausing agitation for about four minutes, agitating in a second opposite direction for about two minutes, and pausing agitation for four minutes. This wash cycle may be repeated up to three times. The articles are then tumbled dried to a moisture level of about 20 percent. The drying process is completed by static drying the articles without mechanical action until all remaining moisture in the articles is removed. The static drying step is conducted at a temperature between about 280 degrees F and about 300 degrees F.

Abstract: An athletic shoe is convertible from a low-top shoe to a high-top shoe. The convertible shoe includes a sole portion, an upper attached to the sole portion, and a detachable high-top. A securing strap secures the high-top to the upper. Both the upper and the detachable high-top include a series of slots through which the securing strap extends. To secure the high-top to the shoe, the securing strap is fed through each of the slots in the high-top and the upper respectively.

Abstract: The present invention relates to a yarn core construction suitable for forming a flexible composite yarn having a fiberglass component. The resulting yarn has good cut and abrasion resistance qualities without sacrificing knittability, flexibility and suppleness. A normally hard to knit fiberglass strand is wrapped with a sheath strand at a rate of at least 8 turns per inch. The core thus formed provides all of the benefits of a fiberglass supported yarn without experiencing any of the manufacturing difficulties normally associated with fiberglass yarns. The core may also be provided with a multi-layer covering to balance the yarn and to further improve knittability.

Abstract: The present invention is directed to a leak resistant battery cover for storage batteries. The battery cover provides a labyrinth of passages which provide a path from each cell vent to the atmospheric vent. The labyrinth is configured to provide a portion of each path above a level in which the electrolyte in the respective cells attains when the battery is tipped on any one of its sides or rotated ninety (90) degrees from an upright position. The labyrinth configuration prevents electrolyte from reaching the atmospheric vent and spilling out of the battery.

Abstract: A decorative glass sheet and a method and apparatus for forming the same. The decorative glass sheet includes a glass panel having opposed surfaces with at least one decorative band formed in at least one of the surfaces. The decorative band includes a roughed band which provides a frosted appearance. A remaining portion of the surface is not covered by the decorative band. The decorative band contrasts with the remaining portion of the surface to provide a unique visual effect including the simulation of a muntin on the glass panel. In preferred embodiments, one or more straight walled grooves are formed in the surface parallel to and immediately adjacent the roughed band.

Abstract: The present invention is directed to a fabric capable of reflecting electromagnetic waves. The fabric contains metal-coated (preferably aluminum) glass fibers bonded together with sheath-core binder fibers. The glass fibers are typically less than 11/4 inches long and the binder fibers are originally approximately 2 inches long. The glass and binder fibers are thoroughly mixed and spread across a flat surface, such as a conveyor, prior to heating. After heating, the mixture is compressed to form the reflective fabric.

Abstract: The present invention is directed to a leak resistant battery cover for storage batteries. The battery cover sealably engages a conventional battery housing having multiple cells separated by internal housing walls. The cover has a substantially flat interior area, a portion of which extends over part of each battery cell when the cover is placed upon a battery housing. The cover includes a cell chamber for each battery cell. Drain-back/vents communicate each cell chamber with its corresponding battery cell. The drain-back/vent, whether separate or integrated allows escape of electrolyte gases from the battery cells into the corresponding battery chamber and provide for the return of liquid electrolyte back to the cells from the cell chambers. None of the cell chambers communicate directly through the battery cover to atmosphere.One or more additional chambers are provided in the cover above the central cells of the battery housing.
