Abstract: A safe locking mechanism has an engagement element movable from a disengaged position to an engageable position in response to a small amount of electrical power. When in its engageable position a mechanical linkage assembly is driven by the engagement element to unlock a lock-bolt. The mechanical linkage assembly includes a low inertia pivoting cam which interacts with a lock lever of the locking mechanism to move it to an unlocking state. Electrical power is generated solely while the user manually inputs a combination code, and a microprocessor controls storage and delivery of this power to put the engagement element into its engageable position. Once the desired engagement is obtained, the lock-bolt is moved from its locking to its unlocking position manually. Subsequent unlocking requires another entry of the code input.

Generally, the compositions comprise parallel layers of mixed valence vanadium oxides with guest cations intercalated between the layers. The guest cations may comprise metal coordination complexes with bidentate ligands, monomeric ammonium or diammonium cations, or mixtures of alkali metal cations with monomeric ammonium cation or diammonium cations.

Abstract: A container including an outer shell, a flexible bag within the outer shell, a mouth and a handle. The outer shell has a top, a bottom and sidewalls. The outer shell also defines an opening. The flexible bag within the outer shell defines an aperture. The mouth is secured to said flexible bag surrounding said aperture and defines a fluid passageway. The mouth is sized and shaped such that fluid can be poured through the mouth from a source having an outlet spaced above the mouth. The handle extends outward from said top of said outer shell and has sufficient strength to provide essentially all support for said container when the bag is filled with liquid in either of two positions, with the first position being where the opening is facing upwards and the second position being where opening is facing sidewards. Desirably, the mouth and opening are sized and shaped such that when the opening is facing upwards the human eye can detect when a level of fluid in the container is approaching the mouth.

Abstract: A carton blank including a reinforced hang tab. The hang tab includes a tab having an upper portion, a top edge defined by a fold line and a cutout formed in the upper portion. A foldover panel is connected to the tab at the fold line. The foldover panel has first and second side flaps and a middle bridge portion that define a notch formed in the foldover panel. Upon assembly, the foldover panel is folded along the fold line and secured to the tab so that the notch overlaps the tab cutout to form a reinforced hang tab with an opening formed therein. The first and second side flaps and the middle bridge portion of the foldover panel reinforce the opening and the upper portion of the upper tab to prevent the tab from easily ripping or breaking. The lower tab that is secured to the bottom portion of the upper tab is configured to correspond to the notch in the foldover panel.

Abstract: A method and apparatus are provided for measuring pressure in a combustion chamber of an internal combustion engine is provided with a non-intrusive, metal-embedded fiber optic pressure sensor. A Fabry-Perot Interferometer is arranged in a terminated, single mode fiber to function as a pressure gauge. The fiber Fabry-Perot Interferometer (FFPI) is embedded in a metal part which is disposed in the cylinder head of the engine. The metal part and FFPI experience a longitudinal compression in response to the pressure in the chamber. In another aspect of the invention, a non-intrusive fiber containing the FFPI is embedded in a hole drilled or otherwise provided in the metal housing of a spark plug. The spark plug is threaded into the cylinder head of an internal combustion engine and is directly exposed to the combustion chamber pressure. Consequently, the spark plug housing and FFPI experience a longitudinal strain in response to the pressure in the chamber.

Abstract: A non-contact laser-based sensor guided by a precision mechanical system scans a thread form producing a set of digitized images of the thread form. The digitized images are analyzed to derive quantitative information about thread characteristics such as pitch, lead, root radius, flank angle, surface roughness, helix variation, and pitch diameter. Thread form data may be stored and later retrieved in order to provide traceability and verification of thread form measurements to a predetermined thread form specification. The apparatus and method of the invention can measure characteristics for shapes similar to threads, such as gears and dies used for cold forming processes. The thread measurement system can be mounted on thread making machines and used for on-line monitoring and control of the thread forming process.
