Filed: 1987-04-06
Abstract: A highly interconnected analog network is constructed with inter-neurons (e.g., 16-18) that account for energy function terms of order greater than two. The network comprises analog amplifiers that are connected with a resistive interconnection matrix (30) which connects each amplifier output to the input of all other amplifiers. The connections embodied in the matrix are achieved with conductances whose values are computed in accordance with the set of problem restrictions, while the cost variables of the problem which are to be minimized are incorporated in the input signals.

Abstract: Water-in-oil emulsions of cationic water-soluble copolymers which are prepared by incorporating only a portion of the cationig monomer in the aqueous phase prior to forming the water-in-oil emulsion in which polymerization will occur, forming the emulsion, adding the balance of the cationic monomer, and then polymerizing the monomers. Copolymers prepared by this new process show improved performance over conventionally prepared cationic copolymers.

Abstract: The ethanol is produced by extracting the raw materials with an aqueous medium, fermentation of the extract containing fermentable saccharides, and working-up of the resulting ethanol-containing fermentation liquid by distillation. In an embodiment which makes the process particularly safe to operate and to be able to dispense with complicated apparatus, in particular in the extraction stage, and to keep the resulting amounts of waste substances to be disposed of and the energy required as low as possible without suffering lower yields, at least part of the slop, which is rich in water and which is obtained as a residue when the fermentation liquid obtained is worked up by distillation, is recycled for extraction in counter-current with the raw materials. In a plant according to the invention, the extraction arrangement comprises essentially a series of containers (3a, 3b, 3c, 3d) which are connected to each other and which are under atmospheric pressure and in whose inner space there is provided in each case a separating wall (29a, 29b, 29c, 29d) which does not extend down to the bottom of the container (Fig. 1). <IMAGE>

Abstract: Composite membranes are prepared by depositing a separation layer on an asymmetric support layer. The separation layer has a selectivity equal to or greater than that of the material of the asymmetric support layer for a desired gas separation. The support layer is desirably produced in non-asymmetric form, and exposed to an elevated temperature approaching the glass transition temperature of the support layer material under non-swelling conditions to modify the structure thereof to create asymmetry therein, before or after the deposition of the separation layer, and to increase its compaction resistance and collapse pressure. Such desirable properties are conveniently achieved on a repeatable basis, enhancing the uniformity and reliability of the treated support layer and of composite membranes produced therefrom for use in gas separation operations.

Abstract: The furniture, such as table, armchair, shelf or the like, consists of a frame and at least one plate which is attached to said frame by means of a bracket, the latter being constructed as a lever which is mounted such that it can be rotated and fixed on the frame, to which lever the plate is attached so that it can be rotated and fixed. The adjustability in height of tables, workplaces, chairs, shelves, etc., is of particular importance where the users of the furniture vary in size. The solution proposed uses a very simple technique, taking the law of leverage into account. Starting from a height-adjustable piece of furniture of the type mentioned initially, it is proposed that the lever, constructed as a disc, is mounted rotatably and eccentrically on the frame and can be fixed, for example, by plugs on the stands or side cheeks of the frame, the plate being mounted rotatably at any desired point on the disc and being attached at a second point on the disc, for example, by plugs. <IMAGE>
