Abstract: An assembly for providing a saggar for use in high temperature applications, may include a rectangular base element and first and second sets of two rectangular wall elements, wherein the rectangular base element includes connectors on two opposite sides for connecting with the two rectangular wall elements of the first set of the rectangular wall elements at the two opposite sides. The two rectangular wall elements of the first set may each include a connector at a first edge for connecting with the rectangular base element at the two opposite sides, and the two rectangular wall elements of the first set each may include two recesses in a second edge opposite to the first edge and in the vicinity of each end of the second edge of the rectangular wall elements of the first set. The two rectangular wall elements may each include two ears for connecting with the recesses.

Abstract: An assembly for providing a saggar for use in high temperature applications, may include a first substantially rectangular base element and two sets of two substantially rectangular side elements, wherein the side elements of each set of side elements have at least one dimension corresponding to dimensions of first and second opposite edges of the base element. The assembly may also include four corner elements and fasteners, wherein the base element and the side elements are configured to be assembled into a box-shaped saggar and secured to one another using the corner elements and the fasteners, and wherein the first base element is made of a corrosion resistant material.

Abstract: A bag-making device for cross base bags limits the number of quality defects resulting from the fabrication tolerances of the conveyor belt. The device has working stations that perform working steps on bag tube sections during the bag making operation. At least one working station is equipped with a tool that is mounted on a tool roller and that runs through its working position during each rotation of the roller. The bag-making device has a conveyor system that conveys the tube sections through the working stations with conveyor belts, and a drive system that drives conveyor drive wheels and the tool rollers such that the drive wheels are driven with lesser angular speed than the tool rollers.

Abstract: The invention deals with a bag-making device for cross base bags. The task of the invention is to suggest a device that restricts the quality defects brought about by the fabrication tolerances of the conveyor belt. What is innovative and inventive about the invention is that the bag-making device has several working stations (30, 31) that implement several working steps on the tube sections (1). At least one working station (30, 31) is equipped with a tool that is mounted on a tool roller (7, 9) and that runs through its working position during each rotation of the roller (7, 9). Furthermore, the bag-making device disposes over a conveyor system (3, 4, 6) that conveys the tube sections (1) through several working stations (30, 31) and consists essentially of conveyor belts (3) and also a drive system (5, 12) that drives the drive wheels (4) and tool rollers (7, 9) and coordinates their rotary motions.

Abstract: A device for the cross perforation of webs, preferably paper webs for producing sacks, comprises a rotatingly driven perforating blade and a grooved roller, both of which are mounted on a machine frame and between them passes the web to be perforated. To adjust the penetration depth of the teeth of the perforating blade into the ring grooves of the grooved roller, there is at least one adjusting device for changing the distance between the axes of rotation of the perforating blade and the grooved roller.

Abstract: The invention relates to a method of manufacturing an anti-oxidation system for porous ceramics on the basis of SiC or Si.sub.3 N.sub.4. By means of infiltration into the pore inner spaces of a sol containing at least one metal component, conversion of the sol to a gel (sol-gel process) and a subsequent high-temperature treatment, it is possible successfully to provide a crystalline anti-oxidation layer, which is resistant to temperatures of up to at least 1650.degree. C. even under cyclic temperature stresses, and reveals a heat expansion behavior adapted to the SiC or Si.sub.3 N.sub.4 over the entire temperature range used.
