Abstract: Some aspects of the present application include a wearable, see-through display device. The device includes a source of video information and a micro-display configured to receive video information from the source of video information and to project light forming an image based on the video information. The device also includes a lens system comprising one or more lenses, the lens system configured to receive and collimate light from the micro-display and to propagate the light from the micro-display to an image guide and the image guide positioned to receive light from the lens system and direct the received light to a partial reflector. The device also includes a partial reflector configured to reflect the light received from the image guide out of the display device towards a place where an eye of a user wearing the see-through display device may be positioned.

Abstract: A process for producing granular detergents, cleaners or components thereof from dust-like solids having a particle size distribution such that at least 5% by weight of the solids have a diameter smaller than 0.1 mm, by placing the solids in a moving mixer and adding water in its vaporous state to the solids whereby the water in its vaporous state forms liquid water in situ on at least part of the solids in an amount of from 0.1% to 2% by weight, based on the weight of the granular detergents, cleaners or components thereof.

Abstract: A storable, substantially water-free flowable surfactant mixture containing 40% by weight to 70% by weight of a nonionic surfactant of the formula R.sup.1 --(OC.sub.2 H.sub.4).sub.n --OH wherein R.sup.1 is an alkyl or alkenyl group containing 10 to 20 carbon atoms and an average degree of ethoxylation n of from 1 to 8; 20% by weight to 50% by weight of a nonionic surfactant, liquid at room temperature, of the formula: R.sup.2 --(OC.sub.2 H.sub.4).sub.r --(OC.sub.3 H.sub.6).sub.p --OH wherein R.sup.2 is an alkyl or alkenyl group containing 10 to 20 carbon atoms, an average degree of ethoxylation r of from 2 to 8 and an average degree of propoxylation p of from 1 to 6; and 1% by weight to 10% by weight of a C.sub.10 to C.sub.22 carboxylic acid and/or alkali metal salts thereof. The flowable surfactant mixture provides a base for forming a pseudo-plastic detergent formulation.

Abstract: A process for improving the adhesion of finishes to oiled and/or hydrophobicized leathers wherein oiled and/or hydrophobicized leathers are treated before prefinishing and/or in the prefinish with aqueous dispersions containing(A) short-chain and/or medium-chain alkyl ether phosphates and(B) finely divided, soft, urea-group-terminated, aliphatic anionic polyurethane dispersions.
