Abstract: Hydrocarbon and steam are introduced into a reformer 102 to form a gas mixture including carbon monoxide, carbon dioxide, water vapour and hydrogen. After removal of the water vapour, the gas mixture is passed to a pressure swing adsorption (PSA) plant 122 comprising first and second arrays 124 and 126 respectively of adsorber vessels. The gas mixture is separated in the plant 122 into a non-adsorbed hydrogen product, a carbon dioxide-enriched fraction, a part of which is recycled to the reformer 102, and a carbon monoxide-enriched fraction withdrawn from an intermediate location of the plant 122. The carbon monoxide-enriched fraction is separated in a further PSA plant 148 to produce a carbon monoxide product. The kind of PSA plant 122 may be used outside this process to separate gas mixtures containing three or more components.

Abstract: The main starting point was that the workpiece (13) can be clamped between two holding punches (11, 12) designed as counter tools, a link (18) carries, at its two jaw edges, in each case one of two bending tools (24, 26), and a drive device (20) for essentially vertical tool movements is provided outside a drive device (19) for essentially horizontal tool movements. The intention is, with a small outlay, on the one hand to permit rapid switching to the other bending tool, and, on the other hand, to offer ample space for bending workpiece parts projecting a long way. The link (18) is therefore divided, in a manner of a hinge, into two cheeks (16, 17) which can pivot separately about the link axle (23) and each carry one of the two bending tools (24, 26), and a drive device (20, 21) is articulated on each of the two cheeks (16, 17) for essentially vertical tool movements. The drive device (20) assigned to the upper bending tool (24) is preferably designed for the larger maximum travel. The bending device can be employed universally in an enlarged field of use since wider plate flanges and, ultimately, more complicated edge profiles can be produced. <IMAGE>

Abstract: A technique for collecting changes to working memory objects made by rule execution in an artificial intelligence production system avoids frequent use of a matching algorithm by delaying the match processing of the collected changes to a memory object until completion of an executing rule. A change to an object wrought by execution of a rule is signified in a control block for that object. Once a first change has occurred, subsequent changes caused before execution of the rule is complete will be made to the object and indicated by the change block. When execution of the rule is complete, the changes coalesced in the object itself are registered in the system by introduction of the changed object into the matching algorithm. This avoids match processing the object each time it is changed during execution of the rule.

Abstract: A synthesizer is disclosed in which error correction pulses from a phase detector (205) are separated into narrow pulse width and wide pulse width pulses. The wide pulse width pulses are coupled to the loop filter (233,235,237) to enable a rapid charge of the loop filter. The narrow pulse width pulses are filtered by a narrow bandwidth filter (225,226,227) before being applied to the loop filter thus enabling a slow charge of the loop filter. The narrow bandwidth filter is decoupled from the control line but referenced to the control line voltage by a buffer amplifier (259) to preserve the adaptive nature of the loop.

Abstract: A display device which is especially suited for application as a center-high-mounted stop-light (CHMSL) or brake light for an automotive vehicle includes a white linear light source (12). A coupler panel (14) or sheet formed of a fluorescent dye-doped material couples light from one edge therethrough to an opposite edge from the light source (12) to a light receiving edge of a display panel (16). The coupler panel (14) transmits red light therethrough, absorbs other colors of light, and re-emits the absorbed light as red light. The display panel (16) has a first surface formed with optical quality, light reflecting grooves (18), which reflect and disperse the edge coupled light out a second surface which is opposite to the first surface. The display panel (14) viewed from the first surface is transparent at all times. The display panel (14) viewed from the second surface produces a red light pattern reflected from the grooves (18) when the light source (12) is turned on, and appears transparent when the light source (12) is turned off.
