A through-air apparatus for drying or bonding paper, tissue, or nonwoven webs is provided. The apparatus includes a web-carrying structure configured to move and a first component having at least one sealing element adjacent the web-carrying structure, where the sealing element is configured to reduce the infiltration of ambient air into the through-air apparatus. The apparatus also includes at least one channel configured to direct air to the sealing element to reduce the infiltration of ambient air into the through-air apparatus. A method of operating a through-air apparatus for drying or bonding paper, tissue, or nonwoven webs is also provided. The method includes directing air to a sealing element to reduce the infiltration of ambient air into the through-air apparatus.

An outlet box assembly includes a base and a connection assembly. The base defines a base through-hole. The connection assembly is configured to attach to the base through the base through-hole and includes a connector and an adapter. The connector includes a connector body. The connector body includes an inner surface that defines a passage with one or more internal threads positioned along the inner surface. The adapter includes one or more external threads configured to engage with the one or internal threads of the connector body. The adapter defines a longitudinally-extending adapter through-hole configured to receive one of a fitting or a tubing. The adapter further defines at least one longitudinal slot configured to allow the adapter to radially compress when the adapter is attached to the connector.

This gland for a sealed feedthrough of an orifice of a partition using a filiform component such as an electric cable, in particular, of the type including: a gland body for the passage of the filiform component, sealingly fixed to the partition to be passed through opposite the orifice; a seal in the form of a deformable sleeve, placed in a corresponding housing of the gland body, around the component; and a component forming a rammer for compressing the seal in the form of a deformable sleeve and deforming them in the housing of the gland body against the filiform component, so as to provide the seal between the gland body and the filiform component. The seal in the form of a deformable sleeve is in the form of a stack of annular seals.

In the grommet, it is assumed that a point at a leading end position of the extension portion is a point A, and a point at a position furthest from the point A as seen in the insertion direction in a leading end region of the fitting portion in the insertion direction is a point B. It is assumed that a width of the through hole in a cross section that is parallel with the insertion direction and passes through the point A and the point B when the fitting portion is fitted to the through hole is a hole width W. At this time, a total of a linear distance L between the point A and the point B and a thickness T of the seal lip is larger than the hole width W.

A waterproof unit including: a first waterproof tube that has a tubular shape and is to be attached to a through hole of a vehicle body panel disposed between a waterproof area that requires waterproofing and a non-waterproof area that does not require waterproofing; a second waterproof tube that has a tubular shape and is to be disposed in the non-waterproof area so as to be spaced apart from the first waterproof tube; and a first exterior tube that has a tubular shape, is disposed between the first waterproof tube and the second waterproof tube, and is coupled to the first waterproof tube and the second waterproof tube, wherein the first exterior tube has higher flexural rigidity than the first waterproof tube to be kept from coming into contact with the first waterproof tube when the waterproof unit is bent in the non-waterproof area.

Vacuum-tight electrical feedthrough 10, comprising an electrically insulating insulator element 2 having a through-opening 23, having a first boundary surface 21 adjacent to the through-opening, and having a second boundary surface 22 also adjacent to the through-opening and opposite to the first boundary surface, and an electrically conductive conductor element 1 which extends through the through-opening 23 and which is connected to the insulator element 2 in a vacuum-tight manner along a circumferential line of the conductor element 1,

wherein the insulator element 2 is transmissive to electromagnetic radiation 25 in an optical wavelength range, and

wherein the first boundary surface 21 and/or the second 22 boundary surface is formed as a curved surface, in particular as a convex or concave surface.

The invention further relates to a vacuum pressure sensor having the vacuum-tight electrical feedthrough and a method for measuring a radiation intensity of electromagnetic radiation.

A seal for a protrusion from an exterior wall of a structure includes a sheet made from flexible material, the sheet comprising a wall cover portion and a protrusion engaging collar. The protrusion engaging collar extends outward from the wall cover portion and defines a hole. The collar has a first inner perimeter adjacent to the wall cover portion and a second inner perimeter spaced from the wall cover portion. The first inner perimeter is larger than the outer perimeter of the protrusion and the second inner perimeter is equal to or smaller than the outer perimeter of the protrusion. The collar provides a seal around the outer diameter of the protrusion when installed.
