Abstract: A sensor element includes a substrate (10) having a coating (31) on a portion of the substrate (10). The coating (31) is applied to the substrate (10) by dipping the portion of the substrate (10) into a slurry which includes a pulverized mineral and water, extracting the substrate (10) from the slurry in a direction along an axis, drying the coated substrate (10), and firing the coated substrate (10) so as to promote densification of the mineral and adhesion of the mineral to the substrate (10). The coating (31) after firing has a minimum thickness of about 100 microns at every location around the periphery of a cross section through the substrate (10) taken in a plane normal to the axis. A method for making a coated sensor element is also disclosed.

Abstract: An oblong shaped box for tissues or papers with an opening (21) on top through which tissues or papers are removed one at a time. Moving the bottom up is made possible by folding in the lower sections of the four sides along punctured fold lines (30), and crushing in the corners along lines (40, 60). Lines (50) near but inside the borders of the bottom create the needed space to allow the bottom to move up.

Abstract: A cylinder head 1 has four valves 2, 4 per cylinder and the desirable arrangement whereby the sparking plug 7 electrodes are in the center of the four valves. The sparking plug 7 is housed in a tube 29 to protect it from the oil in the valve gear region of the head. By appropriate choice of dimensions, it has been found possible to operate the valves 2, 4 via rockers 9, 11 by means of a camshaft 18 located in the vee-space between the valves, while still allowing room to accommodate the sparking plug 7. A desirable compactness is thereby achieved.
