Abstract: Bookbinding unit eliminating the necessity of a user, in placing collated inner leaves onto a tray, pre-measuring the bundle thickness, and the danger of fingers getting pinched during the placement. Furnished with: inner-leaf tray; coversheet tray; gripping conveyor gripping and transporting bundles of leaf-tray sheets; coversheet conveyor feeding coversheet-tray covers and placing them in a binding location; adhesive applicator applying adhesive to bundle spine-portion endfaces; cover binder binding bundles and covers together; and controller encasing bundles in covers to form booklets. A first detector, in the inner-leaf tray, detects thickness of bundles therein, and a second detector, in the gripping conveyor, detects thickness of the gripped bundles. The controller prohibits the gripping conveyor from conveying inner leaves out from the inner-leaf tray when the thickness of a sheet bundle detected by the first detector is more than a predetermined thickness.

Abstract: A liquid detergent composition contains:(A) an anionic surfactant having the formula (I):RO(CH.sub.2 CH.sub.2 O).sub.n SO.sub.3 M (I)wherein R is a C.sub.10 -C.sub.18 alkyl or alkenyl group,n is 0 to 5, andM is hydrogen, an alkaline metal cation, an alkaline earth metal cation, an ammonium cation or a substituted ammonium cation; and(B) an amphoteric ion surfactant having the formula (II): ##STR1## wherein R' is a C.sub.10 -C.sub.16 alkyl or alkenyl group, provided that the weight ratio of component (A) to a total amount of components (A) and (B) is 0.2 to 0.8 and the total amount of components (A) and (B) is 0.05% to 0.3% by weight.

Abstract: Disclosed are novel curing agents for polyurethanes comprising reaction products of (1) a polyoxy alkylenepolyamine with (2) an alpha-substituted acrylic acid derivative wherein the substituent has a terminal hydroxyl group or (3) with a compound having an oxyrane ring and reaction products of (1) and (2) above, with (3) and (1) and (3) above, with (2). Also disclosed is a process for making polyurethanes by condensing a polyol with an isocyanate in the presence of the present curing agents in an amount ranging from 5 to 100 percent by weight of the polyol.
