Abstract: This invention provides a composition comprising: a) an amount of a chromium-EDTA complex; and b) an amount of riboflavin or an amount of glucose, or a mixture of riboflavin and glucose.

Abstract: A seal housing body, extruded AL or molded plastic or metal, has cavity portions communicating through an interface region formed by one at least one frangible projection protruding from the first body into the cavity, a first cavity portion for receiving a locking body, the second cavity portion forming a shackle receiving passageway. The locking body has a channel inclined relative to and in communication with the passageway. A spring in the channel urges a shackle locking ball up the channel partially into the interface region, the ball, having a diameter sufficient to pass through the passageway, is captured in the channel by the at least one projection. The locking body has indicia and/or flanges, at one or both opposing ends, to provide tampering evidence. The channel is offset from the locking body's central plane forming a single channel side wall to preclude trapping the ball by tampering.

Abstract: A utility meter clamping ring is locked to the meter by a locking device that locks the free ends of the ring together automatically without the use of a separate plunger device. A latch is spring loaded in the locking device housing in a normally biased lock position. The lock device is secured to one free end of the clamping ring. An apertured blade is attached to the other free end of the clamping ring. The ring is placed about the flanges of the meter cover and base flanges and the blade is then inserted into the locking device housing where its aperture is engaged automatically by the spring loaded latch and locked to the housing upon insertion. A conventional plunger key may optionally be used to unlock the latch and release the blade from the locked position to free the ends for removal of the meter cover via an optional bore in the latch engaged by the key. The latch may be optionally permanently locked to the blade so that either the locking device or the ring has to be destroyed.

Abstract: One end of a stranded steel cable is attached to a cast zinc seal housing having a chamber in which a steel sleeve with a tapered bore is positioned. The sleeve in one embodiment is fixed to the housing in the chamber or may be displaceable and captured in the chamber in a further embodiment. A serpentine clip locking member captured in the housing chamber resiliently radially grips the a second end of the shackle inserted into the sleeve bore and wedges and locks to the cable and sleeve when the shackle is withdrawn. The sleeve precludes damage to the softer zinc housing by the locking member when the locking member is displaced in the housing chamber. Various embodiments are disclosed. In a further embodiment, the one end of the cable exits the housing in a plane different than where the second end enters the chamber to enhance ease of insertion of the second end into engagement with the locking member.

Abstract: A filament seal for use with stranded or solid metal or thermoplastic filaments comprises a segmented housing defining a chamber in which a locking insert element is positioned, the insert comprising a thin circular disk of hardened stainless steel with a plurality of radially inwardly extending resilient cantilevered fingers each terminating with a tapered sharp pointed tip in abutting or closely space relationship defining a space substantially smaller than the diameter of the filament. The inserted filament bends the fingers and is softer than the insert, the tips digging into the filament during use. When the filament is withdrawn, the finger tips dig further into the filament severing it. If the filament is rotated in an attempt to thread the filament out of the insert, the insert rotates with the filament due to the digging action of the tips into the filament, precluding filament withdrawal from the insert.
