A glass run channel is a groove, normally made of rubber or plastic, that is found around windows (most commonly car windows). [1] [2] [3] The primary purpose of a glass run channel is to provide a seal for the window.
This image shows the components needed to make a rotary union; a shaft, housing, bearings, seals and retaining clip. The independent shaft and housing allow for continuous rotation of either component. This is an example of a two passage rotary union with independent channels that allow both liquids and gases to transfer simultaneously. [1]
Typical O-ring and application. An O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, forming a seal at the interface.
A standard channel letter is a three-dimensional graphic sign element. Its channel is fabricated from sheet metal, most often aluminum since it will not rust. A flat sheet of aluminum is typically cut on a table by a computer-controlled router, laser, or water jet, based on a vector-based art file (.cdr, .eps, .ai, .scv, .sci, or .fs).
In domestic applications, traps are typically U, S, Q, or J-shaped pipe located below or within a plumbing fixture.An S-shaped trap is also known as an S-bend.It was invented by Alexander Cumming in 1775 but became known as the U-bend following the introduction of the U-shaped trap by Thomas Crapper in 1880.
A seal is a device or material that helps join systems, mechanisms or other materials together by preventing leakage (e.g. in a pumping system), containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets .
There are two main categories of diaphragm valves: one type seals over a "weir" (saddle) and the other (sometimes called a "full bore or straight-through" valve) seals over a seat. In general, straight-through diaphragm valves are used in on-off applications and weir-type diaphragm valves are used for control or throttling applications.
A can seamer is a machine used to seal the lid to the can body. The lid or "end" is usually tinplated steel (food) or aluminum (drinks) while the body can be of metal (such as cans for beverages and soups), paperboard (whisky cans) or plastic. The seam formed is generally leak proof, but this depends on the product being canned.
