Patent EP-0038573-A1 (EP)
Inventor: GOOSSENS BERNHARD DIPL-CHEM DR
IPC: C08F20/54
Filed: 1979-12-21
Abstract: The invention relates to a process for the preparation of  alpha , beta -unsaturated N-substituted carboxylic acid amides, novel  alpha , beta -unsaturated N-substituted carboxylic acid amides, a process for the polymerization of these novel  alpha , beta -unsaturated N-substituted carboxylic acid amides, including the polymers, and the use of these polymers as sedimentation, flocculating, dewatering and retention aids, as additives for mineral oils, and as ion exchangers. The  alpha , beta -unsaturated N-substituted carboxylic acid amides are prepared by transamidation of  beta -hydroxy or  beta -alkoxy carboxylic acid amides with primary amines and heating of the N-substituted  beta -hydroxy or  beta -alkoxy carboxylic acid amides obtained as intermediate products in the vapor phase in the presence of catalysts. Primary amines are preferably used in the conversion which have no hydrogen beta to the amino group. These  alpha , beta -unsaturated carboxylic acid amides may be neutralized and/or quaternized and polymerized by processes which as such are known alone or with other comonomers, and preferably acrylic or methacrylic acid derivatives such as acrylamide, to give cationic polymers. These polymers are suited for use as flocculating and sedimentation aids, as dewatering and retention aids in papermaking, as additives for mineral oils, and as ion exchangers.

Abstract: A parallel arm clamp assembly (16') has longitudinally-movable elongate slide members (28',30') mountable transversely on the front of a lift truck and attaching members (32') for connecting forwardly protruding relatively narrow opposing clamp arms (18',20') to the ends of the slide members to as to extend perpendicular thereto. Each slide member (28',30') has an elongate rear portion (28a', 30a') longitudinally mounted within a slide guide (24', 26') and a longitudinally-extending elongate front portion (28c', 30c') external of the respective guide protruding forwardly therefrom. The clamp arm attaching members (32') each have a pair of legs (32a', 32b') formed monolithically and homogeneously into a single member with the legs oriented at substantially a 90° angle with respect to each other. One leg (32a') of each member is connected in end-to-end abutment with an end surface (28d', 30d') of a respective front portion (28c', 30c') of a slide member so as to be in a common plane with the latter. The second leg (32b') of each attaching member (32') protrudes forwardly for end-to-end jointing with the rear edge of a respective clamp arm (18',20'). The arrangement provides a mechanically strong and fatigue stress resistant clamp arm mounting structure without physically restricting load-handling capacity.

Abstract: The actuator comprises a stack of bimetallic discs 18 and 20 in a housing 12 and held under compression by a spring loaded follower 32. The discs are concave to the right when cold and to the left when hot but are of two kinds, namely discs 18 with a lower transition temperature T1 alternating with discs 20 with a higher transition temperature T2. At temperatures between T1 and T2 the stack is expanded as shown. Below T1 and above T2 the discs all nest within each other and the stack is retracted. In an alternative embodiment permanently concave discs alternate with the bimetallic discs and the stack is then retracted below T1, fully expanded above T2 and intermediately expanded between T1 and T2.
