  • Patent number: 4692128
    Abstract: A pulley construction for use in a continuously variable power transmission arrangement. The conical working surfaces of the drive pulleys and the driven pulleys are comprised of removable segments formed of material which is relatively erodable so that the conical pulley surfaces will wear away before the drive belt. The segments are to be replaced when their surfaces have been eroded too much. The replacement of the pulley face segments is simpler and less expensive than replacing the belt, and the use of a relatively erodable pulley face prolongs the life of the belt.

  • Patent number: 4685566
    Abstract: A sleeve-type beverage can carrier having end dust flaps which mechanically interlock by means of locking tabs and cutouts. The flap containing the cutouts overlaps the flap containing the locking tabs so that the cutouts and tabs are aligned. The locking tab is folded back to allow the flap with the cutouts to be moved into place, then is inserted through the cutout and also through the portion of the bottom flap from which the locking tab was struck. This provides a secure mechanical lock. In addition, the blank from which the carrier is formed is designed so that the space between dust flaps is identical in shape to that of the dust flaps. This allows multiple widths of blanks to be cut from the sheet stock without scrap loss.

  • Patent number: 4681217
    Abstract: A wrap-around article carrier with a handle portion bounded by space slits extending across the width of the top panel. The fingers and thumb are intended to be inserted into cutouts covered by tabs the outer boundaries of which comprise part of the slits. The fingers can then extend under the handle portion so as to use it as a strap. The width of the tabs is half the distance between the fold lines attaching the tabs to the handle portion so that the tabs meet beneath the handle portion to form a layer of double thickness. The handle portion is further provided with score lines, four of them being arranged so that the surfaces connected to them fold downwardly about them. The surfaces connected to the fifth fold line, which is centrally located and which extends in the direction of the handle, fold upwardly about it. This arrangement directs the lifting stresses outwardly to the side panels.

  • Patent number: 4673594
    Abstract: A method for directing a stream of bulk fibers while simultaneously spraying a solution of high temperature resistant tacky binder material into the stream of fibers. A layer of high temperature insulating fibers on a furnace, kiln, or other surface to be thermally protected may thus be formed. The layer of binder coated fibers is then cured to a monolithic layer.

  • Patent number: 4663894
    Abstract: A flexible drainage gutter for use under a horizontal surface having moisture accumulation or leaks under cracks or expansion joints. A flexible, waterproof membrane is attached along its elongated edges to rigid flanges which can be attached to the horizontal surface itself or to support members attached to the surface. The width of the membrane can vary so that the membrane hangs down from the flanges a greater distance downstream than upstream, thereby providing for the slope of the gutter. Alternatively, the wall portions of the flanges, to which the edges of the membrane are attached, can vary in width while maintaining the width of the membrane constant to provide for the slope of the gutter.

  • Patent number: 4664969
    Abstract: A method for spray applying refractory fiber to a surface. An alumina containing binder, preferably aluminum chloride, is used in a spray method to bond the fiber to itself and to a substrate surface. A refractory layer comprised of fiber and binder produced by the method of the invention is also disclosed.

  • Patent number: 4637515
    Abstract: A wrap-around article carrier with a handle portion bounded by spaced slits extending across the width of the top panel. The fingers and thumb are intended to be inserted beneath the slits. Upon lifting the carrier, the handle portion adjacent the slits folds upwardly about a score line in the handle portion, directing the stresses caused by the lifting force outwardly to the side panels. This arrangement makes it more convenient to lift the carrier and strengthens the handle portion.

  • Patent number: 4634622
    Abstract: A lightweight asphalt roofing product wherein the asphalt-based coating has a specific gravity less than 1.0. A lightweight filler is used which has an effective specific gravity in the range of 0.10-0.50 and is present in the coating in the range of 3%-25% by weight of the filled coating. In a preferred embodiment, the filler particles have hollow, gas filled inclusions, and comprise expanded perlite particles or expanded permicite particles.

  • Patent number: 4579078
    Abstract: An applicator for metering a desired amount of a liquid sizing onto moving glass filaments. In a first embodiment, a foam-covered roller is partially immersed in a reservoir of liquid sizing and is in contact with the smooth surfaced applicator roll. The foam-covered roller is driven in the same direction as the applicator roll and a puddle is formed above the roller/roll nip. The pressure exerted by the foam covered roller on the applicator roll and rate of rotation of the applicator roll determine the size of the puddle, which controls the amount of sizing applied to the glass filaments. A second embodiment employs an elastomeric reservoir which sits generally atop the applicator roll. A plurality of slots in the rotationally downstream side of the reservoir dispense the sizing onto the roll with the pressure between the elements and rate of rotation of the applicator roll, again, determining the application rate. The sizing is pumped through a closed loop to keep its temperature and viscosity more uniform.
