An adjustable backless, strapless bra comprises a pair of bra cups and a connector, wherein a fixing plate is disposed along a lower edge of each bra cup and a plurality of engagement holes are formed in the plate, and the connector has at least one engagement protrusion formed at each end for detachably connecting to the engagement holes, such that the connector adjoins the bra cups by each engagement protrusion being connected with the engagement holes of the bra cups separately to adjustably modify positions of the bras.

The present disclosure relates to impellers with removable and replaceable vanes, and methods of constructing such impellers. According to aspects of the present disclosure, a plurality of impeller back plates are provided with differently configured slots to receive removable vanes. In addition, a plurality of differently configured vanes are disclosed which may be connected to the plurality of impeller back plates. As a result, the desired performance characteristics of a pump based upon end use applications may be efficiently and quickly achieved by combining appropriately configured vanes and back plate into a desired impeller providing the desired characteristics, together with a particular pump casing and motor.

A method for producing polyvinyl alcohols by means of catalytic reactions of alcoholic polyvinyl ester solutions in extruders, wherein the polyvinyl esters are based exclusively on ethylenically unsaturated monomers and wherein one or more neutralising agents are added to the product of the catalytic reaction.

A method for producing a water absorbent resin by (i) polymerizing a monomer including an unsaturated monomer containing a carboxyl group, in the presence of an internal cross-linking agent (A) having two or more radical polymerizable unsaturated groups and in the presence of a non-polymeric internal cross-linking agent (B) having two or more functional groups each allowing formation of an ester bond or an amide bond by reacting with a carboxyl group, while crushing a cross-linked polymer hydrogel; and (ii) drying the cross-linked polymer hydrogel of step (i), wherein: an amount of the internal cross-linking agent (A) is 0.01 mol % or more and 0.2 mol % or less relative to an amount of the unsaturated monomer containing a carboxyl group, and a molar ratio (B) / (A) of the internal cross-linking agent (A) and the non-polymeric internal cross-linking agent (B) is 0.01 or more and 1.8 or less.

A method for producing polyvinyl alcohols by means of catalytic reactions of alcoholic polyvinyl ester solutions in extruders, wherein the polyvinyl esters are based exclusively on ethylenically unsaturated monomers and wherein one or more neutralizing agents are added to the product of the catalytic reaction.
