Abstract: A composition comprising a halopolymer, such as an ethylene/chlorotrifluoroethylene copolymer, an effective stabilizing amount of an ionomer, and an effective stabilizing amount of a compound such as a phosphite of an organic polyhydric phenol; a thioester; a phosphite; or a hindered phenolic antioxidant. Preferred ionomers are metal salts of ethylene-acrylic acid copolymers, and metal salts of sulfonated polystyrenes. The stabilized halopolymers have improved resistance to thermal degradation and suffer less discoloration when subjected to high melt processing or extrusion molding temperatures.

Abstract: A padlock type security seal and method of making same include a U-shaped shackle, a pair of reversely bent end portions, and a transparent body having a pair of chambers for receiving the bent end portions. The chambers each have a locking groove therein for receiving the bent end portions. The seal elements are formed from two molded thermoplastic pieces, an insert and a body. The relative dimensions of the chambers, the shackle, and the locking grooves are chosen to prevent picking.The insert has a channel in which a liquid filled vial is inserted. The vial contains a colored liquid. When the shackle is attempted to be removed from the body portion, the shackle end portions penetrate the insert and the vial causing the liquid to seep into the various chambers, the seepage being visible through the body.

The rod is slightly curved or bowed and provided with screw receiving transverse holes.

Abstract: There is provided an improved coated composite article and an improved process for making the article. A cloth-like flexible preform is brazed to a metallic substrate to make the article. The article is then subjected to a uniform high pressure and temperature for sufficient time to remove porosity in the coating. The result is a fully dense coating, which is metallurgically bonded to the substrate without any porosity, which has improved physical properties, and which is capable of being polished to a surface finish of at least 4 RMS.

Abstract: To extract a liquid from a workable mass of material a first force is applied to the material in a first direction. A second opposed force is applied to the material within or slightly downstream of a liquid-extraction location. These opposed forces tend to compact the material to extract the liquid. The extracted liquid moves out of the liquid-extraction location along a path which extends generally transverse to the direction of the first and second forces. Third forces are applied to the material along the path in a direction generally opposite to that taken by the exiting liquid to prevent the material from traversing the path but to permit the liquid to exit. The first, second and third forces form a pinch point on the material within or slightly downstream of the liquid-extraction location to substantially obviate liquid flow countercurrent to the direction of the first force.

Abstract: An improved flaring tool includes the usual plurality of expandable die blocks retained by a U-shaped frame. A clamping screw is treaded through a clamp block which is rotatably mounted between the legs of the frame at its open end. The screw is movable toward and away from the die blocks to clamp or unclamp tubing between adjacent die blocks. A conical flaring tip is movable against the end of a clamped tubing for flaring same. The clamp block's axis of rotation is perpendicular to the direction of movement of the die blocks and the screw. The improvement comprises a facility which locks the clamp block against rotation when the screw is aligned with the die block and their direction of movement. The locking facility prevents unintentional rotation of the clamp block as the screw is rotated to clamp or unclamp the tubing, but may be manually overcome to intentionally rotate the clamp block.

Abstract: A seal and lock includes a flexible metal cable held permanently at one end in a housing, the other end being insertable through the housing and is locked therein by a spring-biased ball which wedges against the cable upon an attempt to pull the cable from the housing. A second ball is located between the spring and the first-mentioned ball, and wedges against the cable to further prevent removal thereof and to prevent twisting of the cable as a way of removing the cable from the housing. The second ball is of sufficiently soft material so that the cable when pulled digs into the second ball to increase the jamming force against the cable.

Abstract: A reading light, disclosed in the context of an aircraft reading light, includes a lamp which is normally selectively aimable by swiveling a mounting assembly relative to a stationary base held in a panel. A rotatable two-positioned means, such as a ring, permits such swiveling in a first position of the ring and prevents such swiveling in a second position of the ring.

Abstract: A composition comprising an ethylene/chlorotrifluoroethylene copolymer and an effective stabilizing amount of a phenolic complex of the formula: ##STR1## wherein at least one of R.sub.1, R.sub.2, R.sub.3, R.sub.4, and R.sub.5 is --OH, and wherein the remaining R.sub.1 through R.sub.5 is hydrogen or an aliphatic hydrocarbon, and wherein each of R.sub.1 through R.sub.5 may be the same or different provided that at least one of R.sub.1 through R.sub.5 is --OH, and each of R.sub.6 and R.sub.7 is an alkylene group having from 1 to about 10 carbon atoms, and each of R.sub.6 and R.sub.7 may be the same or different. The composition may further include a phosphite, a thioester or sulfide compound, and/or an inorganic filler such as tricalcium aluminate hexahydrate. Such compositions show improved melt stability at high temperatures and are useful as wire and cable coatings, films, and pipes.

Abstract: A retractable step is movable from a position located in a cavity to an extended position located outside of the cavity. The invention provides for a latching facility to hold the step in the extended position against the bias of a retracting spring. A person standing on the step, exerting a downward force thereon disengages the latching facility. As the downward force is removed from the step, the step automatically retracts in response to the bias of the retracting spring.

Abstract: A surgical saw having a base blade portion, a plurality of staggered teeth and an intermediate blade portion, the thickness of which is less than the thickness of the base blade portion. The thickness of the intermediate blade portion is sufficiently less than the thickness of the base blade portion to permit passage of bone cuttings and other material away from the staggered teeth during operation of the surgical saw.
