Abstract: The chair has legs (9, 10), a seat (3) and a backrest (4) which is of integral construction with the seat, the legs (9, 10) being constructed as hollow plastic parts, in which metal tubes (17, 18) are received as reinforcement elements. Each leg (9, 10) preferably comprises two plastic halves (14, 15, 11, 12) which have inwardly projecting parts (22, 24) with snap-in edges or teeth (23, 25) which interact with snap-in openings (21) in the metal tubes (17, 18). The inner plastic halves (14, 11) of one front and one rear leg (9 and 10) are advantageously made integrally with an essentially horizontal element (8) which bounds or supports the side edge of the seat, in that the outer plastic halves (15, 12) of the front and/or rear leg (9 and 10) are separately manufactured parts which are snapped onto the tubes as leg caps. It is also advantageous if the chair or armchair has a backrest part (7) which comprises at least one rear wall (36) with two side walls (37) and is attached between the rear legs (10) with the aid of said side walls, the backrest (4), designed as a trough in integral construction with the seat (3), being mounted against the side walls (37) of the rear back piece (36). Finally, the trough (3, 4) is preferably constructed as a plastic part which is provided with a padding. <IMAGE>

Abstract: A remotely controllable circuit breaker has an improved scheme for effecting rapid arc extinction as well as protecting the breaker contact from the resulting arc current. The breaker includes first and second movable contacts  11  and  12  which are held respectively on parallel extending first and second contact arms  31  and  32  and are driven individually by a switching mechanism  20  including a manual handle  22  with a contact trip capability and by a remotely controllable switch  60 . An arc runner  115  is connected to be in the same electrical potential as the second contact arm  32  and extends in the contact separating direction for receiving the one end of the arc developed between the rapidly separating contacts  11  and  12  and guiding the arc toward an arc extinguishing chute  110  as the first contact  11  moves away from the second contact  12 . The arc runner  115  is connected at its end opposite to the arc chute  110  to an arc drive member  116  which extends immediately behind the second contact arm  32  in parallel relation thereto and is cooperative with the first contact arm  31  to develop electromagnetic repulsion forces therebetween upon the occurrence of the arc by the effect of the current flowing through the first contact arm  31  and the arc drive member  116  in the opposite directions. The repulsion force acts to urge the arc toward the arc chute    110  for rapid arc extinction. At this time, the arc current will bypass the second contact arm  32  for protecting it from the overcurrent.

Abstract: A high performance computer graphics image computation system architecture is disclosed. The system architecture includes a computational processor ring which includes a plurality of closely coupled computational subsystems. The computational subsystems operate asynchronously and each is interconnected with two adjacent computational subsystems. The architecture of the processor ring allows rapid communication between the computational subsystems while avoiding a deadlock condition. The system architecture also includes a video processor ring wherein a plurality of video processors are synchronously linked together. A plurality of local communication paths couple the computational subsystems to the video processors. The video processor ring is able to move massive amounts of data, in the form of digital video signals, from various points within the system. The computational processor ring is able to rapidly carry out graphic image computation tasks and graphic image data is moved around in the system by way of the video processor ring. The embodiments of the present invention allow the components of the computational processor ring and the video processor ring to be variably configured as one or more logical machines, each logical machine being assigned a particular graphic image computation task. The described embodiments are also readily expandable so that components may be added to the computational processor ring, the video processor ring, or at other locations in the system.
