  • Patent number: 5104568
    Abstract: 2,2'-oxodisuccinate detergent builder salts (ODS), especially tetrasodium 2,2'-oxodisuccinate, are difficult to dry and tend to pick up water due to the hygroscopicity of the 2,2'-oxodisuccinate: yet the present invention secures improved granular built detergent compositions comprising ODS by an aqueous ODS/zeolite coagglomeration process, the resulting agglomerate being remarkably stable and nonhygroscopic. Other detergent ingredients, such as perborate bleach, surfactants and the like, can be dry-mixed with the agglomerates to form fully-formulated granular detergents. The invention encompasses the agglomeration process, the ODS agglomerates and granular detergent compositions containing same.

  • Patent number: 4691987
    Abstract: In a flexible, fiber optic belt 16 for the coherent transmission of light from an LED light source 22 a planar array of fiber optic filaments 34 extend along the length of the belt 16 and are positioned by transverse elements 79 along the major neutral plane of the belt. The fiber optic belt 16 is restrained to movement only in the direction normal to the major neutral plane by means of one or more rigid flat strips 25 parallel to the major neutral plane and the light source 22 is thermoelectrically cooled to improve the availability of light supplied by the diodes. In a method for producing the fiber optic cable, transverse positioning elements 79 are layered on a cable mold 56, one or more fiber optic filaments 34 are placed upon the transverse positioning elements 79. Fiber optic filaments 34 are pressed onto an adhesive layer adjacent to the LED's 48 and bonded by the melting of the adhesive.
