Abstract:
A continuous process for the manufacture of a ceramic sintered comopact wherein the process comprises the steps of: forming a green compact from a powder mixture comprising a first component comprising compounds which contain elements of silicon, aluminum, oxygen and nitrogen; and the powder mixture further comprising a second component comprising a compound of at least one element selected from the group consisting of yttrium, scandium, cerium, lanthanum and the metals of the lanthanide series, and the second component comprising between 0.1 and 10 weight percent of the powder mixture; heat treating the green compact wherein the heat treatment comprises continously passing the green compact through at least one heating zone so as to produce a sintered compact.
Abstract:
To simplify the production of cans (3, 103, 103'), especially aerosol cans, the can production plants are fitted with magnetic conveyors (6, 8) associated with magnetisable pallets (7, 107, 107') instead of chain conveyors with pins. The cans are secured on the magnetisable pallets (7, 107, 107') and taken by magnetic belt conveyors (6, 8) to or through processing stations. The pallets (7, 107, 107') are secured by a riveting process to a connecting piece (132) projecting from the can base (130) and guidable through a connection aperture (117) in the pallet (7,107, 107'). The cans (3, 103, 103') may be given any direction on the magnetically secured pallets (7, 107, 107') by the suitable arrangement of the conveyor surfaces (8) on the magnetic conveyor (6, 8). The can aperture is always freely accessible during conveying. There are belt conveyors with back-up regions (46) to compensate feed variations in the plant by simple means.
Abstract:
A ceramic conveyor belt (1) including a plurality of columns (300) of ceramic bars (3) having holes disposed through opposite ends. The columns are separated by ceramic spacers (13) having corresponding holes (30). The aligned holes form a cross-passage through which a ceramic cross rod (5) is disposed. An annular groove (50) is disposed about the ends of the cross rod extending beyond the outer columns. A ceramic end tab (9) includes a hole formed therethrough defined by a peripheral wall. A portion of the peripheral wall fits within the groove (50), leaving a space between the end tab and the groove (50) on the opposite side of the end tab (9). A ceramic putty is disposed in the space, and hardens over a portion of the end tab (9) preventing radial movement of the end tab with respect to the rod (5), thereby preventing axial movement as well.
