A grommet includes a cylindrical portion and an attachment portion formed to project from an outer peripheral portion of the cylindrical portion. An annular groove into which an inner peripheral edge portion of the through-hole can be fitted is formed in an outer peripheral portion of the attachment portion. A bottom face of the annular groove is formed with a racetrack shape having a pair of straight portions and a pair of arc portions that are formed with an outwardly convex arc shape and respectively connect end portions of the pair of straight portions on one side and end portions on the other side. Inner peripheral portions of the arc portions include portions in which the thickness dimension gradually increases from the centers of the arc portions toward connection portions that connect the arc portions to the straight portions.

The valve box support pad is a thick rubber pad made from recycled auto tire scraps or virgin rubber by a compression molding process using a polyurethane binder and is designed to be placed below-grade under irrigation valve boxes to both support the valve box and prevent gophers or other burrowing mammals from backfilling their tunneling spoils into the valve box. What is new about this invention is that it replaces the industry standard bricks, gravel and aviary mesh used in setting/constructing an irrigation valve box assembly. The pad also reduces the amount of excavation required in setting a valve box.

A support clip for attaching a fluid-carrying tube or line to a substrate is disclosed that provides an air tight seal on a single fluid-carrying tube or line or on multiple fluid-carrying tubes or lines when the tubes are secured between two different surfaces. The support clip has two mated elastomeric surfaces defined by upper and lower halves that account for minor surface-to-surface variations while still maintaining an air tight seal. The lower half is attached to a substrate in a vehicle by a locating anchor. Each half has a rigid body and an elastomeric portion. The rigid body maintains the form of the elastomeric portion. At least one tube-holding channel is formed in the elastomeric portion of each of half. When the two halves are fastened together by an interference fit, the air tight seal is established. The halves may be fastened together by a variety of mechanical arrangements.

A seal assembly (10) for sealing an opening (12) in a wall (14) or ceiling of a building, especially for sealing a line penetration, wherein the seal assembly (10) is able to cover the opening (12) and has a passage (32) for a line (18), has at least two disk-like seal segments (16), which together define the passage (32) at inside rim portions and in circumferential direction overlap at adjacent rims (22). A seal segment (18) for such an assembly has an elastic sealing compound (26) that is applied on a carrier film (28).

The fire and smoke containment services transit unit includes a casing constructed from a material having a thermal conductivity of less than 5 watts per meter per Kelvin. The casing defines a first opening at a first end and a second opening at the second end. Intermediate the first and second end is the internal volume that is encased by the casing. The internal volume and each of the openings are sized to allow services such as cables, pipes, etc. to be threaded through the services transit unit. An intumescent material is housed centrally within the internal volume. Prior to exposure to the heat of a fire, the intumescent material maintains a slim profile. However, when the transit unit is exposed to the heat associated with a building fire, it swells and thereby seals the internal volume against the passage of fire, smoke or heated gases through the transit unit.

The invention relates to a method and to an apparatus for producing a plug-through connection arrangement of a plurality of electrical cables (1a-1d) and/or fluid-conducting hoses, having a sheathing (2) consisting of a plastic, which extend, arranged adjacently spaced apart from each other, through associated openings (3a-3d) of a plastic component (4), comprising the following steps: providing (A) the plastic part (4) with the pre-produced plurality of openings (3a-3d), installing (B) the electrical cables (1a-1d) and/or fluid-conducting hoses through the associated openings (3a-3d), such that the outer wall of the sheathing (2), which consists of plastic, comes into contact with the inner wall of the respective openings (3a-3d) of the plastic component (4), thermal welding (C) of the electrical cables (1a-1d) and/or fluid-conducting hoses to the plastic component (4) in the region of the respective opening (3a-3d), in order to produce an integrally sealing component bond, wherein at least two laser beam units (5a, 5b), positioned opposite each other, are aligned to an associated initial connection point, after which the oppositely positioned laser beam units (5a, 5b) are activated and caused to undergo a linear relative movement crosswise to the orientation of the openings (3a-3d), in order to create the integral bond by surface melting of the sheathing (2) together with the plastic component (4).
