Abstract: A pointing device comprises a stick coupled to a resilient return member which is supported on a substrate along an outer edge to move relative to an upper substrate surface of the substrate. The upper substrate surface has conductive lines and resistive coatings formed thereon or embedded therein. The return member has a conductive surface which is biased with a voltage and is normally spaced from the upper substrate surface. When an user applies an external force to the stick to move the return member toward the substrate, the conductive surface makes electrical contact with the substrate surface and generates a digital signal. The conductive surface is convex to provide rolling contact with the substrate surface to change the contact location. The conductive surface is deformable to allow the area of contact to increase with an increased external force for a change in resistance.

Abstract: A process for the continuous production of N-(phosphonomethyl)glycine is provided. In the process, N-(acetyl)iminodiacetic acid is formed in an amidocarboxymethylation reactor system. The N-(acetyl)iminodiacetic acid product stream is either: (1) reacted with a source of phosphorous and a source of formaldehyde in the presence of an acid to form a phosphonomethylation reaction product stream containing N-(phosphonomethyl)iminodiacetic acid and acetic acid; or (2) deacylated and cyclized to form a 2,5-diketopiperazine, and then reacted with a source of phosphorous and a source of formaldehyde in the presence of an acid to form a phosphonomethylation reaction product stream containing N-(phosphonomethyl)iminodiacetic acid and acetic acid. In either case, the N-(phosphonomethyl)iminodiacetic acid product is recovered and converted to N-(phosphonomethyl)glycine.

Abstract: Novel compounds, N,N′-bis(phosphonomethyl)-N,N′-bis(hydroxycarbonylmethyl)urea and N,N,N′,N′-tetrakis(hydroxycarbonylmethyl)urea, suitable for use in preparing N-acyl aminocarboxylic acids that can be readily converted to N-(phosphonomethyl)glycine are provided. The compounds may be formed by the reaction of bis-(phosophonomethyl)urea or urea respectively with carbon monoxide and formaldehyde in the presence of a carboxymethylation catalyst precursor and solvent.

Abstract: An ergonomic pointing device comprises an orb controller coupled to a resilient return member which is supported on a substrate to move relative to an upper substrate surface of the substrate. The substrate surface has conductive lines and resistive coatings formed thereon or embedded therein. The return member has a conductive surface which is biased with a voltage and is spaced from the substrate surface at rest. When a user applies an external force to the orb controller to move the return member toward the substrate, the conductive surface makes electrical contact with the substrate surface and generates a digital signal. The conductive surface is convex to provide rolling contact with the substrate surface to change the contact location. The orb controller has a curved control surface which is contacted by a digit of a human hand to manipulate movement of the conductive surface relative to the substrate surface. The orb controller has a substantially smaller height than a joystick.

Abstract: A pointing device comprises a substrate with an electrically conductive surface and a resilient boot. The resilient boot resiliently supports a resistive surface to contact the electrically conductive surface in a pressed mode when a force is applied to push and deform the resilient boot against the electrically conductive surface. The resilient boot is made of a resistive rubber material. The resistive surface has a voltage variance and is curved to be rocked on the electrically conductive surface in the pressed mode. The voltage variance is detected on the electrically conductive surface and a variable signal is generated and processed. At least one inner switch is provided near the center region of the electrically conductive surface and the inner switch is activated by the resistive surface in the pressed mode. When the force is removed, the resistive resilient boot returns to its undeformed state and the resistive surface is spaced from the electrically conductive surface in a rest mode.

Abstract: Process for the preparation of an N-acyl amino carboxylic acid by means of a carboxymethylation reaction. In this reaction, a reaction mixture is formed which contains a base pair, carbon monoxide, hydrogen and an aldehyde with the base pair comprising a carbamoyl compound and a carboxymethylation catalyst precursor. In a preferred embodiment, the carbamoyl compound and aldehyde are selected to yield an N-acyl amino carboxylic acid which is readily converted to N-(phosphonomethyl)glycine, or a salt or ester thereof.

Abstract: A process for the production of N-(phosphonomethyl)iminodiacetic acid. N-(acetyl)iminodiacetic acid is formed in a amidocarboxymethylation reactor system, into which a source of each of the following is continuously fed: (1) acetamide or an acetamide derivative, (2) formaldehyde or a formaldehyde generator or derivative, (3) a carbonylation catalyst, (4) carbon monoxide, and optionally (5) hydrogen. In turn, an amidocarboxymethylation reaction product stream, which contains N-(acetyl)iminodiacetic acid and the carbonylation catalyst, is withdrawn from the amidocarboxymethylation reactor system. The carbonylation catalyst is separated from the amidocarboxymethylation reaction product stream to recover the carbonylation catalyst and form a catalyst depleted product stream which contains N-(acetyl)iminodiacetic acid.
