According to the disclosed embodiments, an illustrative apparatus that is configured to attach to a viewport of a container comprises a first plate having a first aperture and an attached second plate having a second aperture substantially aligned to the first aperture. The first and second plates, when attached, define a cavity from an outer edge of the first and second plates to the substantially aligned apertures. A window containment arm is pivotally affixed to at least the first plate and configured to substantially fit and pivot into and out of the cavity, and a window contained within the window containment arm is positioned such that the window substantially aligns with the first and second apertures when the window containment arm is fully pivoted into the cavity, and such that the window is accessibly located outside of the cavity when the window containment arm is pivoted out of the cavity.

A method for replacing a swirler (2) of a premixing or main burner of a burner arrangement (1), wherein the swirler (2) is connected to a distributor flange plate (5) of the burner arrangement (1) via a fuel gas feed pipe (3) and a fuel oil feed line (4) accommodated therein. The fuel gas feed line and the fuel oil feed line are severed to enable removal of the separated end portion of the fuel gas feed line. A sleeve is installed to replace the removed end portion.

An interchangeable knife block that accommodates various numbers and sizes of cutlery utensils. One knife block includes a base, a body having a first end and a second end, wherein the body is coupled to the base at the first end and extends from the base, and a cap removably coupled to the second end of the body and defining one or more slots therein, each slot being configured to receive a portion of a cutlery utensil therein.

Punch holders and corresponding punch configurations configured to increase the ease and speed by which maintenance and/or modification of punches used with the holders can be performed. In some cases, the punch holder can be configured with one or more upper and lower collars operatively situated on differing areas of the holder, with each collar adapted to perform a different action with regard to a punch held by the holder. In some cases, when the upper collar is rotated, a corresponding height adjustment of a punch held by the holder results. In some cases, when the lower collar is rotated, a punch held by the holder is released.

A tool for mounting a chisel on a chisel holder, having an actuating member, which has a push-off section, wherein the actuating member can be displaced along a displacement direction. It is possible to simplify changing the chisel if the actuating member can be shifted by an actuating unit. The actuating unit has a draw-in section, which is spaced apart from the push-off section and is arranged transversely with respect to the displacement direction of the actuating member. The actuating member can be power-operated bidirectionally in the displacement direction by the actuating unit.
