Abstract: These three new types of leveling instruments do not rely on spirit-level-bubbles in glass vials used in dumpy-levels and in tilting-levels, nor on the so called self-leveling pendulums used in the automatic levels. These new types of leveling instruments use a free mercury surface as a mirror to assure that the line of sight through the center of the cross hairs is horizontal, or has a very small but constant inclination from the true horizontal for all pointings to the leveling rods. In the most precise model, the mercury surface is used to autocollimate the line of sight through the center of cross hairs to be horizontal for every pointing. In the less elaborate models, the mercury surface is used to guarantee that the line of sight through the center of cross hairs has only a very small but constant inclination with the true horizontal. It is important that this inclination stays constant, and it can be adjusted to be less than one tenth of one second of arc if so desired.

Abstract: A photographic emulsion coating on a travelling web 1 is irradiated by microwave energy propogated through a slotted, undulating waveguide 5 to condense or concentrate the coating by evaporating a significant percentage of its water content, thereby shortening the overall drying time for a given coating rate. A forced flow of air and/or other gases is established through apertures 9 in the waveguide under controlled temperature and humidity conditions, and the internal heating effected by the microwaves prevents the formation of a surface film which might impede subsequent drying.

Abstract: There is provided a footwear upper construction which includes a toe panel which defines a toe portion and two rearwardly extending side portions, and two ankle panels adapted to be stitched to the inner margins of the rearwardly extending side portions.

These slots are interlaced or interleaved with each other prior to the stitching and the water-proofing which may be applied in the case of boots. The interleaving of the two slots reduces the risk of pin-hole leakage at the forward end of the connection between the ankle panel and the toe panel.
