Abstract: The present invention relates to antibodies binding to IL13 and IL22. The invention provides novel multi-specific antibodies that bind to both IL13 and IL22 and compositions comprising an antibody that binds to IL13 and an antibody that binds to IL22. The invention further relates to therapeutic uses of the combination of anti-IL13 and anti-IL22 antibodies and multi-specific antibodies that bind to both IL13 and IL22.

Abstract: A drop hammer has a hydraulic cylinder and piston assembly with a hammer weight attached to the piston and a sleeve valve at the lower end of the cylinder coaxial with the cylinder. An outer casing surrounds the cylinder, forming an annular passage from the valve to the upper end of the cylinder. Through servo control means that may be automatically operated by the hammer movement, the valve alternately admits pressure to the cylinder space below the piston to raise the weight, and opens said cylinder space to the annular passage to put both ends of the cylinder in communication and allow the hammer weight to fall.

Abstract: A soil compacting device has a vibrator unit dependent from a follower tube and so connected thereto as to be able to swing transversely relative to the tube. The connection is effected by at least one internally disposed flexible tension element such as a rope or cable. A resilient sleeve forms a seal between the adjacent ends of the vibrator unit and the follower tube and restrains relative rotation therebetween. The sleeve is pre-compressed by the tension in the wire or rope. The vibrator unit, sealing sleeve and follower tube form an elongated cylinder-like assembly with a substantially uniform cross-section.
