Title: Continuous preparation of (meth)acrylic acid alkyl esters
Inventor: SCHMIDT WILLI
IPC: B01J31/02
Filed: 1997-02-03
Abstract: In the continuous production of alkyl (meth)acrylates (AA) by reacting (meth)acrylic acid with 1-8 carbon (C) monohydric alkanols in homogeneous liquid phase, free from solvent, at elevated temperature and in the presence of an acid esterification catalyst; (a) (meth)acrylic acid, alkanol and catalyst are fed to a reaction zone; (b) during a residence time, the water formed is separated in a rectification unit (RU) III above the reaction zone; (c) the aqueous distillate is separated into an organic phase containing the alkanol and an aqueous phase; (d) the organic phase is recycled to RU III; and (e) the reaction mixture is discharged from the reaction zone and passed to another RU, where AA is separated by distillation. The novel features are that: (i) the molar ratio of (meth)acrylic acid and alkanol is 1:(0.75-2); (ii) the aqueous phase from RU III is partly recycled to RU III; (iii) the reaction mixture is passed to RU I, in which it is separated into a product (II) containing the catalyst and a product (I) containing AA, residual alkanol and residual (meth)acrylic acid; and (iv) (I) is passed to RU II, in which AA is separated from residual alkanol and residual (meth)acrylic acid and the alkanol and acid are recycled to the reaction zone. Preferably the alkanol is 2-ethylhexanol. The catalyst is para-toluenesulphonic acid (p-TSA) and/or other organic sulphonic acids, e.g. methane-, benzene- or dodecylbenzene-sulphonic acid, and/or sulphuric acid (H2SO4). The catalyst concentration in the reaction mixture is 0.1-10, especially 0.1-6 wt.% p-TSA in the reaction zone and 2.5-50 wt.% p-TSA in the sump or an equimolar amount of organic sulphonic acid and/or H2SO4. The reaction zone consists of a cascade of  NOTLESS  2, especially 2-4 consecutive sections, especially reactors with circulating vapourisers. All rectification units are rectification columns.

Title: Absorption article with multi-directional expanding side parts
Inventor: ROE DONALD CARROLL
IPC: A61F13/15
Filed: 1994-11-18
Abstract: Absorbent articles such as disposable diapers, incontinent briefs, diaper holders, training pants, feminine hygiene garments, and the like, having extensible side panel features that improve the dynamic fit of the diaper around the legs and waist of the wearer. Such absorbent articles include a containment assembly including a liquid pervious topsheet; a liquid impervious backsheet; an absorbent core disposed between the topsheet and the backsheet; and extensible side panels, each including a waist panel and a thigh panel disposed along each longitudinal edge of the containment assembly in the first waist region. The waist panel and the thigh panel are operatively associated so that the waist panel has a primary direction of extensibility in one direction and the thigh panel has a primary direction of extensibility in a different direction. This forms a multi-directional extensible side panel wherein the waist panel provides tension around the wearer's waist to maintain fit about the waist and to hold the diaper on the wearer, and the thigh panel expands and contracts to maintain a dynamic fit around the leg of the wearer. Thus, the waist and thigh panels reduce the negative effects of the dynamic forces on the absorbent article, such as sagging and gapping that can cause leakage, while increasing freedom of motion and wearer comfort.

Filed: 1994-03-31
Abstract: Two or several overlaying sheet formed members are joined together using an essentially coaxial arrangement of a punch, a die with a die cavity, and an anvil. A method for joining the sheet formed members comprises the steps of placing two or several overlaying sheet formed members between the punch and the die, causing a core portion of the punch to move in a direction toward the die cavity so as to co-act with the die cavity to form a cup-shaped or protruding portion having a side wall portion and a bottom wall portion, whereby a lateral extension provided around the rear end of the core portion deforms and axially displaces material from the area around the opening of the cup-shaped or protruding portion, mainly in the upper sheet formed member, moving the anvil in a second direction and locking it in a predetermined position relative to the die, a second relative movement of the punch in the direction towards the die compresses the bottom wall portion whereby a laterally enlarged shape is formed, mechanically interlocking the sheet formed members.
