Patent ES-463268-A1 (ES)
Title: Rotary electric printer
IPC: B41J11/02
Filed: 1977-10-15
Abstract: A discharge-sensitive recording medium (36) is brought into contact with recording needles by means of a conveyor means (56) in that the said medium (36) is moved transversely with respect to the direction of movement of the recording needles.

Title: Fluid damped unit, particularly for use as shock absorber or telescopic strut
IPC: F16F9/48
Filed: 1979-12-14
Abstract: A fluid damped unit includes a cylinder, a piston rod arranged for extending and retracting movement from one end of the cylinder, the rod having a piston at its end within the cylinder, and a damper unit arranged in an annular work chamber formed between the piston rod and the cylinder for damping the movement of the piston rod. The damper unit includes a damping ring which is carried in a damping ring carrier, the ring frictionally contacting the inner circumferential surface of the cylinder. A stop ring is mounted to the piston rod for contacting the damping ring carrier when the piston rod is extended past a predetermind intermediate position toward a fully extended position wherein movement of the piston rod is hydraulically damped. The damping ring carrier is arranged to be fixed in the axial direction of the cylinder when the piston rod is retracted beyond its predetermined intermediate position. Thus, hydraulic damping of the piston rod movement occurs with certainty each time the rod is extended past its predetermined intermediate position relative to the cylinder.
