The ignition conductor contains a light transmitting fiber optic cord bound to the ignition conducting material of the fuse in such manner that if the ignition conducting material is broken, the fiber optic cord is also broken. The claimed subject matter further includes assemblies containing means at the primer end for transmitting light back to the igniter end.

Abstract: It has long been known that there is an interfacial tension between immiscible liquids such as water in oil. It has long been known that membranes when wetted by one of two immiscible liquids will preferentially allow the passage through the membrane of the liquid with which the membrane is wetted, and will reject the other liquid with an opposing force that is proportional to the interfacial tension of the liquids. The opposing force is inversely proportional to the diameter of the pores of the membrane, and can be several inches of water head for pores a couple thousands of an inch in diameter. According to principles of the present invention, a structure is provided which augments the small water opposing force of the above described phenomenon with opposing forces of other mechanisms to produce a combined force which will separate water, without utilizing dirt collecting and annoying water coalescing filters, such as layers of glass fibers, etc.

Abstract: A boot to ski attachment mechanism which provides three degrees of attachment. When the heel is against the ski a threaded detent provides a greatly adjustable retention against vertical separation with full restraint against lateral separation. When the heel is raised out of the detent to an intermediate elevation, only lateral restraint is provided. When the heel is above the intermediate elevation, the heel is free of lateral restraint to allow twisting as during a fall. These three degrees of attachment are provided by upstanding legs on opposite sides of the heel, along with detent mechanism having parts on the upstanding legs and heel. The detent action between the upstanding legs and heel is made infinitely adjustable by a threaded rod and nut arrangement with said nut being carried by either the heel structure or upstanding leg structure while the transverse pin is carried by the other of the heel or upstanding leg structures.
