Abstract: The present disclosure provides processes and apparatus for the production of materials requiring a plurality of chemical reaction steps. In the prior art the number of reaction vessels is minimized by performing two or more reactions together in the same vessel. Instead each process is separated into separate successive steps, in each of which at least two principal components are reacted together, with or without at least one catalyst. In each step the components are reacted under optimum condition for that reaction, using motion-augmented, sub-Kolmogoroff, micro-agitation provided by a separate discrete motor-operated, micro-agitation means. Such means are much smaller in size, but are extremely flexible as to the flow rate and reaction conditions, so that they can be adjusted to suit the reaction, without compromises dictated by attempting to perform other reactions in the same vessel.

Abstract: An open space office system comprises a plurality of freestanding work stations (10) constructed of vertical panels (14) and horizontal work surfaces (12). The room in which the work stations (10) are arranged are provided with a central ventilation means (41) which provides air circulation in the room. Each work station (10) includes at least one common conduit (26) arranged adjacent the work surface (12) thereof. A vent (35) disposed in each of the work stations (10) communicates with the conduit (26) thereby providing an air flow path from the central ventilation system (41) through the room to the conduit (26). In this way, return air of the ventilation system is evacuated from the room by means of the conduits (26). The conduits (26) are typically connected to a central return air duct (42).
