  • Patent number: 7256308
    Abstract: A process for the production of acetic acid by carbonylating methanol and/or a reactive derivative thereof in a carbonylation reactor in a liquid reaction composition comprising an iridium carbonylation catalyst, methyl iodide, methyl acetate, water, acetic acid and at least one promoter selected from the group consisting of ruthenium, rhenium and osmium, characterized in that there is also present in the reaction composition a bis-phosphonate compound having the formula (I): wherein R1, R2, R3, R4 are independently hydrogen or an organic functional group; Y is an optionally substituted C1-C10 alkylene or C6-C10 aryl group.

  • Patent number: 6984081
    Abstract: The invention relates to an adjustable keyboard to be used, for example, at a computer terminal (12). The preferred embodiment is in the form of a keyboard having a number of keys (5), the keyboard being formed in at least two segments (2, 3) which are mutually movable relative- to one another using a hinge or joint (6). Each of the segments (2, 3) of the keyboard has mounted thereon some of the keys (5). The relatively movable nature of the keyboard aims at reducing stress and discomfort to the user by eliminating contortion to the user's wrists. More particularly, discomfort to the user caused by pronation of the wrists and/or ulnar deviation of the wrists is reduced. The hinge or joint (6) may be in the form of a ball and socket-type joint with a locking mechanism, which preferably includes a pivoted handle (100), in the form of a lever, used for locking and unlocking the hinge or joint (6).

  • Patent number: 6296216
    Abstract: A support assembly including first and second mounting brackets each having a mounting surface for attachment to a bottom surface of a desktop, first and second support arms pivotally attached to the first and second mounting brackets respectively to define first and second pivot axes, and a computer keyboard platform having a top support surface and a bottom surface. The first and second support arms rotate in a single plane about the first and second pivot axes respectively. The first and second support arms are pivotally attached to the bottom surface of the platform to define third and fourth pivot axes respectively. The support arms are rotatable relative to the platform in the single plane about the third and fourth pivot axes respectively.

  • Patent number: 6098935
    Abstract: An adjustable support for a data input device and the like including a base attached to an associated worksurface, a platform shaped to support the data input device thereon and having a front portion and a rearward portion, and a support arm having one end pivotally joined with the base, and an opposite end pivotally joined to the rearward portion of the platform. Also included is a locking member fixed to the support arm, and an elongate brake element wrapped around the locking member, and having one end coupled to the base and a second end connected with the platform at a point spaced from the opposite end of the arm such that rotation of the tray about the coupling at the second end of the support arm releases the brake element and permits changes in the elevation of the support with respect to the base, and the moment of the platform and any associated input device tenses the braking element against the locking member and locks the platform in its selected position.

  • Patent number: 6013745
    Abstract: The present invention relates to the polymerization of one or more alpha olefins in the presence of a transition metal catalyst having either a heterobifunctional ligand, having a phosphorus and a nitrogen atom, or a bis-phosphinimine ligand having two nitrogen atoms, in the presence of an activator.

  • Patent number: 5975474
    Abstract: An adjustable support for data input devices and the like includes a base attached to an associated worksurface, a platform shaped to support the data input device thereon and having a front portion and a rearward portion. A support arm has one end pivotally joined with the base, and an opposite end pivotally joined to the platform. A brake element selectively engages a locking member, such that rotation of the tray about the second end of the support arm releases the brake element and permits changes in the elevation of the support with respect to the base, and the moment of the platform and any associated input device frictionally engages the braking element with the locking member and locks the platform in a selected position.
