Abstract: A system and method of the present invention randomly mixes and palletizes various containers received from a conveyor. A control system received an order in advance to cooperate with an automatic storage and retrieval system to pick the containers, ordered by various customers, and to place them on a second conveyor. A robotic device, such as a robotic arm or a gantry system, selectively picks the containers from the second conveyor and places the containers on a pallet in a mixed fashion. The pallets are delivered to the respective customers.

Abstract: Thermosplastic molding materials which contain styrene polymers and polyphenylene ethers whose phenolic hydroxyl groups have been reacted with reactive copolymers.

Abstract: A rotary filter has a pressure vessel and a rotor from which a plurality of filter cells are suspended from outer portions of the rotor so that they clear a conveyor located proximal to the axis of rotation and upon which the filter cake is removed. Conduits are connected to the filter cells from a single distribution head for initially evacuating the cells in the filter stage and thereafter pressurizing the cells to dislodge the filter cake while the vessel remains under pressure. The filter cells can have the filter surfaces extending generally in axial planes or in axially spaced relationship in planes wherein a plurality of angularly spaced filters extend generally radially from respective filtrate conduits running axially along the outer part of the rotor.

Abstract: A simple and economical one-step process for felt-proofing and dimensionally stabilizing textiles, particularly textiles based on keratinous fibers is disclosed. In the process, the textiles are treated with aqueous baths which contain salts of sulfurous acid or pyrosulphites as reducing agents and polyurethanes which contain onium groups.

Abstract: An aqueous solution of bisulphite blocked polyisocyanate prepolymers is imparted improved storage stability at temperatures up to about 45.degree. C by incorporation of about 0.5 to 20% by weight (based on the weight of bisulphite blocked prepolymer) of an aromatic or alkyl aromatic sulphonic acid of the formula:R(SO.sub.3 H).sub.nwherein R is an aromatic or alkyl aromatic hydrocarbon group having 6 to 15 carbon atoms and n is an integer from 1 to 3. The solution may also contain up to 80 volume percent (based on the total quantity of solvent) of an organic solvent miscible with water and having a boiling point below about 150.degree.C. This solution may be used to finish paper, leather or textiles and to shrink proof keratin containing textiles.
