Abstract:
A lateral applicator kit for a pipe has a first application unit and a second application unit that are configured to apply a primer material or other substance to the exterior and interior lateral surfaces of a pipe, respectively. The first application unit is configured to receive primer through a supply engagement feature, which is in fluid communication with a reservoir cavity internal to the first application unit and further in fluid communication with at least one perforated annular wall of an application receptacle configured to receive, and apply primer to, the exterior lateral surface of a pipe. The second application unit is similarly but inversely configured to apply primer to the interior lateral surface of a pipe by receiving primer into a supply receptacle, which is transferred through at least one spout set into and through an annular distributing container connected annularly around the supply receptacle.
Abstract:
A method of depositing an imprintable medium onto a target area of a substrate for imprint lithography is disclosed. The method includes moving the substrate, a print head comprising a nozzle to eject an imprintable medium onto the substrate, or both, relative to the other in a first direction across the target area while ejecting a first series of droplets of imprintable medium onto the substrate and moving the substrate, the print head, or both, relative to the other in a second opposing direction across the target area while ejecting a second series of droplets of imprintable medium onto the substrate on or adjacent to droplets from the first series of droplets.
Abstract:
An application device comprises a liquid tank for retaining a liquid, and a discharge unit to which the liquid is supplied from the liquid tank, and which discharges the liquid to an application-target area of an object at a set application width. The discharge unit comprises a head cylinder filled with the liquid supplied from the liquid tank, and the nozzle plate which is provided at one end of the head cylinder in a replaceable manner and which is provided with plural nozzle holes discharging the liquid. The application width can be changed by merely replacing the nozzle plate without changing of an application condition.
Abstract:
The present invention describes a device consisting of an endless flat conveyor belt arrangement for the positionally accurate transport of containers wherein the flat conveyor belt arrangement comprises two parallel convex load-bearing surfaces (3). In the conveyance of ferromagnetic containers, such as cans (2), for example, magnets (21, 22) are utilized which pull the cans (2) onto the conveyor belts (1).
Abstract:
An apparatus for coating the flat surface of a substrate with a coating material is disclosed in which only a minimum amount of coating material is required for uniformly coating the entire surface of the substrate in an efficient manner under a variety of coating conditions, even if the substrate surface takes a non-circular configuration. According to one embodiment, the flat surface of the substrate is first coated with a coating material, and the substrate thus coated is then spunned at predetermined number of revolutions per minute. According to another embodiment, the apparatus includes a support table on which the substrate is fixedly mounted. A plurality of shaping members are slidably mounted on the support table for forming with the flat non-circular-shaped surface of the substrate a flat continuously extending circular-shaped surface. A plurality of biasing members are provided one for each shaping member for biasing the shaping members radially inwards into intimate contact at their inner sides with the peripheral side surfaces of the substrate mounted on the support table. A plurality of level adjusting mechanisms are provided on the shaping members for adjusting the surface of the shaping members to be flush with the flat surface of the substrate.
Abstract:
A device for applying a protective coating to the weld or solder seam of a can body has an application roller (2) serving to apply a coating material inside a region covering the seam at the inside (15) of the can body. The roller periphery has a cross-sectional profile (5) comprising at least one depression (10) in a middle region (9) of a middle portion (6) having a region width of less than 60% of the width of the middle portion (6). The profile (5) further comprises at least one salient point and/or at least two points of inflection in this middle region (9). The device renders it possible to achieve optimum layer thicknesses of the coating over the seam, which are neither too little for the stresses occurring during the long-term storage of corrosive liquids nor too great for the tearing strength stressing of the coating which occurs during the flanging over of the edges of the can body. As a result of the form of the roller, an optimum profile of the coating layer applied results, with the greatest layer thickness immediately above the seam.
Abstract:
A device for coating the internal threads of a fastener includes a rotatable base for holding the fastener, and an applicator having a discharge orifice extending through its side wall which contacts the internal threads at a single point of tangency, the axis of the applicator being offset from the rotational axis of the base. Thus, an induced side load force is created at the point of tangency for effecting the pressing of discharged sealant into the roots of the threads. Differently sized internally threaded elements can be coated in accordance with the invention while using the same sealant applicator.
Abstract:
A dispensing head for applying adhesive to a contoured surface of one object which is to be bonded to a complimentary surface of another object is disclosed herein. This dispensing head includes two sections, one of which is provided for receiving adhesive from a supply thereof. The other section is provided for applying this adhesive to the contoured surface to be bonded and includes a complementary adhesive applying surface and a network of channels extending between the adhesive receiving section and the adhesive applying surface. While each of these channels is closed along its length during operation of the dispensing head, the section of the dispensing head defining these channels is divided into two disengagably connected subsections for providing ready access into and along the length of each channel.
Abstract:
A method and apparatus are provided for applying liquid to solid surfaces to which access may be limited or restricted. Liquid is continuously fed to an applicator where the liquid clings to a supporting surface to form a bead defining an outwardly exposed meniscus protruding beyond the applicator. The applicator is moved along the surface in a proximate relationship thereto which brings the protruding meniscus into contact with the surface to wipe liquid onto the surface, the applicator all the while being spaced a slight but noncritical distance from the surface. A portion of the liquid wiped onto the surface is immediately aspirated from the surface by suction applied through the applicator to leave on the surface a deposit of liquid controlled in quantity by the degree of aspiration accompanying the wiping of liquid onto the surface. The continuous aspiration of liquid from the liquid bead forming the protruding meniscus on the applicator prevents dripping of liquid from the applicator and functions in conjunction with continuous feeding of liquid to the meniscus to provide a continuous circulation of liquid on the applicator, even when it is awaiting usage, with no fouling of the applicator and no stagnation or deterioration of the liquid on the applicator.
Abstract:
A device for the application of liquids, particularly high viscosity substances, such as glue and the like, comprises a layon member which is inflatable and which is connected to a filling and discharge line for causing the inflation. The device may be used to fill cracks or grooves by placing the lay-on member in the groove or crack and then inflating it. The lay-on member may also include an inner core within the envelope defining a space between the lay-on member and the core for containing the medium to be applied and which will issue from the pores of the member after the lay-on member is inflated.
