Title: Structural member having differential temperature control means and combination of such structural member with horizontal stripper for grate conveyor
IPC: G05D23/19
Filed: 1973-01-10
Abstract: An apparatus for and a method of controlling the temperature differential between different surfaces or walls of a structural member such as a hollow box beam, and a structural member whose temperature differential is so controlled. The invention has important utility in the combination in which it controls the temperature differential between the opposite walls of the box beam which conventionally supports the horizontal stripper member used for stripping hot ore pellets or the like from the surface of a grate conveyor or the like since one of the walls of the box beam which supports the horizontal stripper is normally subjected to much higher temperatures than the opposite wall thereof, causing undesirable deflection of the beam.

Title: Balloon suppressor for light and heavy yarns
IPC: D01H1/42
Filed: 1976-09-17
Abstract: A twisting apparatus for light and heavy yarns has a conventional twister wherein the yarn packages are supported rotatably on a rotating flyer but is inhibited from rotation by magnets on the yarn-package holder and upright walls surrounding the yarn-package holder.
