Patent DE-3826957-A1 (DE)
Inventor: HAESSLER ANDREAS DIPL ING
IPC: F27B9/12
Filed: 1988-08-09
Abstract: A tunnel furnace for burning materials containing flammable materials has, in the furnace channel in the region of the burning zone and cooling zone, the usual small free internal cross-sectional area between charge and furnace inner walls. In the region of the heating-up zone and possibly in a part of the burning zone, this free internal cross-sectional area is, in relation to the remaining free internal cross-sectional area, greatly enlarged. In these regions, the separation between charge and furnace wall or furnace roof and charge is thus considerably greater than in the remaining furnace. In the regions with enlarged free internal cross-sectional area, the furnace gas is guided along a longitudinal surface of the charge in counterflow and along another longitudinal surface in co-flow. The furnace gas flows transversely through the charge upon transition from the counterflow to the co-flow. The removal of the furnace gas is carried out at the rear end, seen in the forwarding direction of the materials, of the heating-up zone and/or at the front end of the burning zone. <IMAGE>

Title: Material for optical cards
Inventor: YANO TAKEFUMI
IPC: C08G18/67
Filed: 1988-09-28

Patent DE-3837824-A1 (DE)
Title: Caster for manually movable equipment
IPC: B60B33/00
Filed: 1988-11-08
Abstract: Secured in its caster fork the caster has an axle on which the caster wheel is mounted. The central region bounded by the wheel rim has a covering disc fitted over it on both sides of the caster wheel. The covering discs of known casters are arranged in the interior of the caster fork and can scarcely prevent the interior of the caster fork from being soiled. The intention is to provide a caster in which apart from protecting the caster axle against being soiled, in particular also the penetration of impurities into the interior of the wheel fork is prevented. The covering discs are secured to the outside of the caster fork which, for its part, already fits over the caster wheel with its fork limbs. This arrangement of the covering discs prevents the penetration of impurities into the cavity of the wheel fork and also protects the bearing region of the caster wheel on the caster axle.
