Abstract: LONGITUDINALLY LACED CONTINUOUS      COIL SPRING ASSEMBLY         Abstract of the Disclosure A spring assembly for mattresses, innersprings, and the like.  The assembly comprises longitudinal rows of coils, each row comprising a continuous length of wire formed into a plurality of coils interconnected by Z-shaped wire segments alternately disposed at the top and bottom of the coils.  Adjacent rows of coils are connected by longitudinally extending helical lacing wires wound through overlapping Z-shaped wire segments. By lacing the rows of coils longitudinally, the spacing between adjacent coils may be varied in selected longitudinal sections of the unit so as to vary the coil count and thus the firmness of selected areas of the assembly, as for examples the center section.  Furthermore, by so lacing the rows of coils, a single set-up of forming and assembly machine may be used to manufacture varous width of mattresses, as for example, twin, double, queen and king size units.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a process for the production of polyurethane urea products from isocyanate product blends and preferably less reactive, aromatic diamines, or solutions of aromatic diamines in relatively high molecular weight polyhydroxyl compounds, the reaction components being reacted in a casting process with commercially-reasonable casting times and compara-tively short demolding times.  For this purpose, rela-tively high-molecular weight polyhydroxyl compounds, optionally in the presence of low molecular weight diols are reacted with excess quantities of toluene, phenylene or hexamethylene diisocyanate to produce a substantially diisocyanate-free NCO-prepolymer.  This NCO-prepolymer is mixed with from 0.1 to 25%, by weight, of less reactive, monomeric tetra-alkyl-diphenylmethane diisocyanates corresponding to the general formula:       wherein R1 to R4, which may be the same or different, represent C-1-C4 alkyl radicals. These isocyanate blends may be easily processed into elastomer moldings having favorable properties in the casting process using moderately-reactive aromatic diamines from the series of di- to tetra-alkyl-diphenyl-methane diamines and/or dialkyl-toluene diamines and/or using substituted 3,5-diamino-4-alkyl-benzoic acid alkyl esters, optionally dissolved in the relatively high molecular weight polyhydroxyl compounds.

Abstract: PROCESS FOR THE PURIFICATION OF WASTE GASES AND FOR HEAT RECOVERY, AND EQUIPMENT FOR        CARRYING OUT THE PROCESS     ABSTRACT OF THE DISCLOSURE          A process and equipment for the purification of waste gases containing pollutants, in particular from firing installations, are described.     A waste gas duct (9) into which a line (12) for a scrubbing fluid leads in the upper region is inserted into the stack (8).          The scrubbing fluid is sprayed into the waste gas duct (9) in counter-current to the waste gas which is to be purified and which flows upwards in the waste gas duct (9).     The scrubbing fluid contains additives which react with the pollutants in the waste gas and bind them.          The scrubbing fluid is passed from the storage vessel (16) downstream in circulation through the waste gas duct (9) and back again into the storage vessel (16).          Advantageously, the latter is designed as a combined storage, sedimentation and reaction vessel, in which the solids formed during the scrubbing step settle and the scrubbing fluid is regenerated.     Heat exchangers (7) and  (23)      are provided which remove from the waste gases a quantity of heat which is otherwise dis-carded unutilized with the waste gases.  (Figure 1)
