Abstract: This invention comprehends a device for producing a clicking sound that is part of the free-floating drag in spinning type fishing reels. When a fisherman is playing in a fish trying to land the fish, it has been found desirable to let the spool rotate slowly letting out a small amount of line so that the line will not snap in two. Since the fisherman is busy an audible clicking sound indicating that the spool is rotating is a help and assistance.

Abstract: A ceramic-metal composite laminate capable of exposure to high temperature differentials without damage, consisting of an inner ceramic layer, an outer metal layer and an intermediate interface layer of a low modulus metallic low density structure having a high melting point. The ceramic layer is secured to the low modulus structure directly or through an intermediate ceramic-metal composite, and the outer metal layer is brazed to the intermediate low modulus layer. Thermal strains caused by a temperature differential between the inner and outer layers are taken up without harmful effect by the intermediate low modulus layer.

Abstract: A thin perforate, helically wound welded edge tubing is used as a filter core for a roving wound filter. The slightly roughened external edges of the spirally formed welded joint greatly adds to the ability of securing the fiber roving to the tube and prevents relative slippage therebetween. Also, the invention comprehends an apparatus for, and a method of making the helically seamed tube by first drawing a sheet metal from a supply and raising two lateral edges thereof to form flanges. The material can be guided in a helical path by engaging the inside of the flanges so that the trailing edge abuts the leading edge. The abutted edges are heated so that the flanges themselves provide the filler for a weld on the exterior surface thereof. Drive rollers are provided to move the welded tube from the welding area and to torque the tube to prevent edge separation prior to the cooling of the weld.

Abstract: Disclosed is a filter medium for removing contaminants, including gels, from molten polymers. The medium contains layers of sintered metal fibers having diameters of 50 microns or less. At least two adjacent layers are separated by a screen, and the screen and layers are bonded together by compression and sintering. Preferably the layers include from 35 to 60 volume percent fibers. The filter medium is graded so that the polymer as it flows through the medium encounters fiber layers having pores that generally decrease in size. The screen has pores that are larger than the average size of the pores in any downstream layer and that are larger than the average size of the pores in the upstream layer immediately adjacent the screen. The screen collects at least some of the gels or other particles that pass through the upstream layer, giving the medium a higher dirt holding capacity than the conventional filter medium.
