The invention relates to a valve (1) for controlling liquids, comprising a valve housing (10) having an actuator chamber (11) and a laterally arranged inlet hole (13) that is connected to a high pressure inlet (12), wherein the actuator chamber (11) has an actuator (30) with a plunger (31) and a round end (32), wherein the actuator chamber (11) has a taper gasket that is configured by means of a conical surface (14) on the end of the actuator chamber (11) and a matching annular sealing surface (33) on the round end (32) of the actuator, wherein a cable outlet (17) can be sealed off with the taper gasket. The actuator chamber (11) has at least another inlet hole (13). This makes it possible to achieve a more even power distribution to the actuator (30).

The invention relates to a damper (1) for furniture, which comprises a housing (2) in which a piston (4) connected with a piston rod (3) is received in a mobile manner. When the piston (4) is displaced in the housing (2), a fluid flows through a flow channel (20) arranged on or in the piston (4). Meanwhile, different damping forces are generated when the piston (4) is displaced in different directions. Thus, parts of the cross section of the flow channel (20) can be modified by displacing the piston (4) relative to a plate (6). The plate and / or the piston is provided with radially extending grooves for forming at least one part of the flow channel (20). One side of the housing is provided with a movable balance piston. The balance piston is hermetically guided on the housing and the piston rod. The balance piston is provided with a sealing member. The sealing member abuts against the housing through an outer sealing lip and abuts against the piston rod through an inner sealing lip.

An automated tipping process for large outer diameter preforms. The regions of the preform are heated and softened in a furnace. Shape the preform tip and control the process by moving the glass above and below the heating zone and by sensing the weight of the lower part of the preform, which is actually the viscosity of the softened material metric. After reaching the correct viscosity, the bottom holder is moved away from the top holder according to a nonlinear acceleration rate profile (derived from FEM simulation of glass flow) that is precisely programmed and controlled such that the preform tip Optimally shaped (usually with short and sharp tips) with minimal waste and waveguide distortion when drawn into fibers. The same concept of the non-linear acceleration rate profile can also be applied to other tipping processes, such as horizontal preform tipping processes.

The invention provides a dual-guiding work roll bending and balancing device of a plate and strip rolling mill. The dual-guiding work roll bending and balancing device of the plate and strip rolling mill comprises a bending and balancing cylinder. A cylinder block of the bending and balancing cylinder is fixedly arranged on the inner side wall of a mill housing. An upper piston rod is arranged on the top of the cylinder block in sealing, penetrating and sliding manners. A lower piston rod is arranged at the bottom of the cylinder block in sealing, penetrating and sliding manners. The free end of the upper piston rod is connected with an upper guide cover, wherein the upper guide cover abuts against the upper portion of the outer wall of the cylinder block in a sliding manner and can move up and down along the mill housing. The top of the upper guide cover abuts against an upper work roll assembly bearing seat. The free end of the lower piston rod is connected with a lower guide cover, wherein the lower guide cover abuts against the lower portion of the outer wall of the cylinder block and can move up and down along the mill housing. The dual-guiding work roll bending and balancing device of the plate and strip rolling mill overcomes the defects that in the prior art, a guide ring and a seal ring are prone to damage, oil leakage is severe, and the use stability is poor. Full-travel dual guide protection is conducted on the upper piston rod and the lower piston rod, and the work stability of the work roll bending and balancing device is effectively improved.

Device for loosely binding printed sheets to form booklets (10) using a loop-like wire binding element (41) comprises two C-shaping devices (50, 50') and two O-shaping devices (60, 60'). The C-shaping devices are positioned so that the initially flat wire binding element is bent into a C-shape. The O-shaping devices are positioned so that the C-shaped wire binding element is bent into a closed shape.
