  • Patent number: 7849902
    Abstract: An apparatus for making a spunbond web has a foraminous deposition belt, a system for depositing fibers on the belt such that some of the fibers engage through the belt, and an output roller over which the belt is spanned for normally advancing an upper stretch of the belt in a transport direction toward the output roller. The output roller has a radially outwardly directed outer surface engaging the belt and formed with a profiling in turn formed by high spots contacting the belt and low spots out of contact with the belt so that fibers engaged through the belt are only pinched between the belt and the output roller at the high spots. The web is pulled downstream off the belt at the output roller.

  • Patent number: 7799157
    Abstract: A pressure-sensitive adhesive layer 3 is formed on a release treated surface of a release liner 4, and gas from holes 40 in the release liner 4 is made to move to the outside of the pressure-sensitive adhesive layer 3, thus forming through holes 31 in the pressure-sensitive adhesive layer 3. The pressure-sensitive adhesive layer 3 and a base material 2 having provided therein gas-passing channels that communicate to the outside of the pressure-sensitive adhesive sheet are then laminated together such that the gas-passing channels in the base material 2 and the through holes 31 in the pressure-sensitive adhesive layer 3 communicate with one another, thus obtaining a pressure-sensitive adhesive sheet 1. According to the pressure-sensitive adhesive sheet 1, air entrapment and blistering can be prevented or eliminated while securing adequate adhesive strength and with no marring of the appearance.

  • Patent number: 6599350
    Abstract: A filtration device for use in filtering air used to purge a vapor storage canister used in connection with a fuel vapor recovery system of an automobile. The device includes a housing. In some instances, the housing may be integral to another component. The housing has a chamber having an arcuate inner surface. Air flowing into the chamber through an inlet port strikes the arcuate interior surface and is redirected such that the air rotates in said chamber. The centrifugal force of the rotating air filters out any contaminants of sufficient mass contained therein. The filtered air is removed via an outlet port positioned near the longitudinal-axis of the chamber. Contaminants removed from the air fall due to gravity or a secondary air flow pattern into a collection portion of the housing.

  • Patent number: 6355081
    Abstract: Oleophobic and hydrophobic filters for filter venting applications are made by forming a polydimethylsiloxane coating on the surface of a filtration substrate. The filters have high water penetration pressures and high air permeabilities. The coatings are formed by polymerizing vinyl terminated siloxane with a crosslinker such as hydrosilicone in the presence of a catalyst. Alternatively, the coatings can be formed by heat curing after exposing the substrate to methyl silicone and crosslinking at high temperature.

  • Patent number: 5468335
    Abstract: Carpeted panels comprising a thermoplastic substrate and a synthetic fiber carpet are produced by bonding the respective pads to one another using a vibration welding apparatus for causing the generation of frictional heat at the interface between the substrate and the carpet. One of the platen of the welding apparatus confronting the carpet is provided with a pattern of closely spaced pins engaging the carpet and urging the carpet into forced engagement with the substrate. On account of the closely spaced pins and the relatively low amplitude of the reciprocating motion, a bond is achieved substantially over the entire interface between the carpet and the substrate.

  • Patent number: 5256238
    Abstract: A carriage for carrying a labeller, bundler or similar tool for working on sheet material spread on a supporting table is moveable vertically and transversely relative to such table by an associated lifting and transport cart allowing the carriage to be lifted from one table and transported to another table at which it is lowered onto the new table to bring it into working relationship therewith. The carriage may be engaged by the cart from the side or end of the table. Accordingly, the carriage may be moved from one table to another even in cases where the carriage can not be easily moved onto or off of the end of a table because of such table end being inaccessible. Means hold the carriage against vertical and lateral movement relative to the table while the carriage is in working relationship therewith, and these means are moveable to disengaged positions to free the carriage for vertical movement relative to the table when removing the carriage from or placing it onto the table.

  • Patent number: 5174850
    Abstract: A tape dispenser, particularly suited for masking tape or like low-tensile strength adhesive tape, and having a frame with a hub portion that provides a cylindrical surface for rotatably mounting a roll of tape and having a central finger-receiving aperture therein. A support wall extends radially from a first side of the hub portion to hold an axially extending flange spaced from a minor segment of the cylindrical surface, whereby the finger-receiving aperture and the flange provide means for grasping the dispenser and not interfering with the rotation of a roll of tape mounted on the dispenser. A swinging arm has one end mounted to the first side of the hub portion, at a location generally radially opposite the flange for rotation about an axis parallel to the axis of the cylindrical surface, and has an application roller mounted at its other end to also rotate about an axis parallel to the axis of the cylindrical surface.

  • Patent number: 5078825
    Abstract: An automatic paper feed device provided in a turnbar unit of a rotary press includes a slitter for slitting a web of paper in half. A paper feed rope having a leader connected thereto is located near the slitter. When the leading end of the web has passed through the slitter, the paper feed rope begins to move so that the leader will be moved in juxtaposition with the leading end of one of the two slitted webs. When the leading end of one of the webs reaches a predetermined position, a tape applicator will be activated to apply tapes both to the leader and the leading end of one of the webs so as to straddle them. The web thus connected to the paper feed rope through the leader is guided by the rope through a predetermined paper feed path.

  • Patent number: 5051147
    Abstract: Described is a cut-sheet lamination using a laminator for the single or double-sided application of a film cut onto a printed circuit board using heated overlay rollers located opposite to each other in a housing. The printed circuit board and the cut film are fed to the overlay rollers simultaneously in the overlay region. The printed circuit board is led in with input rollers, and the film is pulled off a supply reel and is guided over input rollers to the printed circuit board. A cutting fixture is provided within the region of the input rollers. The cutting fixture cuts the film corresponding to the length of the printed circuit board in accordance with a sensor scan. The cutting fixture is put onto a lever capable of swivel motion. The cutting fixture travels along with the film at the cutting of the film, and the lead-in rollers for the film in the region where the cutting occurs are constructed as suction rollers.

  • Patent number: 5037767
    Abstract: In the manufacture of a semiconductor device, e.g. a bipolar or MOS transistor, a narrow beam (4) of ions is deflected across a major surface of a semiconductor device body (1,2) to implant ions, e.g. a boron, into a region (3) of the body. In accordance with the invention a resist mask (5a) is obtained autoregistered with the implanted region (3) by effecting the implantation through a layer (5) of ion-sensitive resist thus exposed by the ion beam (4) in the area (5a) overlying the implanted region (3) at the same time as the implantation occurs into the body region (3). The non-exposed area of the layer (3) is afterwards removed by developing the resist, and the ion-exposed area (5a) is then used as a mask during a subsequent processing step, e.g. an etching or doping step, in the device manufacture. The implanted region (3) may be, e.g., a peripheral base region portion of a bipolar transistor or a parasitic-channel stopper below a field insulating layer (2) of an MOS integrated circuit.
