Title: Aluminium titanate ceramic burner plater for flat gas burner - has good resistance to corrosion and thermal shock and low thermal conductivity
Inventor: FOLLERT ULRIKE
IPC: C04B35/478
Filed: 1990-12-20
Abstract: Burner plate (12) for a flat burner (2), having orifices (12) for fuel gas (4) distributed over the surface, consists of an Al2TiO5 ceramic (I). Pref. (I) is stabilised by adding SiO2, ZrO2, MgO, Fe2O3, Na2O and/ and/or CaO. It has a coefft. of thermal expansion of ca. O +/-1 x 10power(-6) K. The orifices have a cross-section of 0.7-7, pref. 1.7-5 mm2 and are cylindrical, pref. with a conical taper.  The plate is 4-10 mm thick. It is made from a mixt. contg. TiO2 and Al2O3. The pref. compsn. of the starting material is 50-55 (wt.)% Al2O3, 30-35% TiO, 5-10% SiO2, 1-5% ZrO2, 0.5-5% MgO,  0-1% Fe2O3, 0-1% Na2O and 0-0.2% CaO. The plate is produced by moulding the mixt. of starting materials; consolidation, pref. to a density of 1.8-2.3 g/cc; and sintering, pref. for 2-3 hrs. at 1450-1550 deg. C. The mould has pegs to form the orifices and the mixt. is pressed with a plate with holes corresp. to the pegs. ADVANTAGE - The burner plate is more durable than metal plates, which are corroded by impurities, esp. chlorohydrocarbons in the gas, and allows the min. flame temp. to be reduced. It has a very low coefft. of thermal expansion, which (almost) eliminates thermal strain and gives high resistance to thermal shock, preventing the formation of microcracks. The low thermal conductivity ensures that the back of the plate remains relatively cool, preventing back-firing.
Patent DE-4102306-A1 (DE)
Inventor: MIERBACH ALBIN DIPL PHYS
IPC: F16J9/06
Filed: 1991-01-26
Abstract: A piston ring 1 has an outer periphery which deviates from the contour of the oval bore of a cylinder 2. When constrained in the bore without its cooperating inner spring, the piston ring exerts a force against the cylinder; although, in the regions A, A surrounding the major diameter, the outer periphery of the piston ring does not make contact with the inner periphery of the cylinder. When its cooperating spring is arranged within the inner periphery of the piston ring an additional outward bias is provided and compels the entire outer periphery of the piston ring to be in contact with the cylinder. Furthermore, the total force thus exerted against the cylinder is uniformly distributed around the inner periphery of the cylinder. In one embodiment, the major diameter of the piston ring in the unconstrained state is shorter than the major diameter of the bore of the cylinder. <IMAGE>
