Abstract: The invention relates to a rolling mill for sizing tubes or cylindrical bodies such as bars, rods and so on, and is intended for the iron and steel industry. The rolling mill is made up of a multiplicity of fixed three-roll rolling units, i.e. of the type known per se in which the position of the rolls cannot be adjusted under load and they are kinematically connected to each other so as to be set in rotation simultaneously, downstream of which are a multiplicity of adjustable three-roll rolling units. In the latter units the position of the rolls can be adjusted even under load and the purpose of these is to carry out the finishing of the work that is to be sized. The invention enables excellent use to be made of the characteristics of strength of the fixed units and of accurate working of the adjustable units, with the result that it is possible to build an inexpensive but high-performance rolling mill.

Abstract: The recreation of vibration levels at certain points in a stationary vehicle interior that are representative of realistic road conditions are achieved using road measurements in conjunction with a technique known as "reciprocal filtering." The reciprocal filtering technique consists of using an inverse transfer function, or impulse response in the time domain, between an excitation transducer and an accelerometer to calculate the excitation signal needed to recreate the vibrations measured on the road when squeak and rattle are present in a component of the vehicle. A set of excitation signals may be recorded for each component in the vehicle which is suspected of producing squeak and rattle noise. When a complaint is made that a vehicle is producing squeak and rattle, a service technician may reproduce noise by inducing vibrations through a kit having a CD player, an amplifier, a bass shaker and a CD with the set of excitation signals stored on separate tracks thereof.

Abstract: A threaded leadscrew moves axially within the housing of a linear actuator. The leadscrew's movement rotates a threaded gear nut that surrounds the leadscrew. Stopping the gear nut rotation prevents leadscrew translation. The locking mechanism for selectively blocking rotation of the gear nut includes a cam mounted on the housing, which connects remotely to a user actuated handle. A lever, which mounts on the cam, has a tooth movable between adjacent teeth on the gear nut. The cam also has a blocker that engages the lever. When the cam is in the closed position, the blocker prevents the lever from moving to its released position away from the gear nut's teeth. When the cam is moved to the released position, the blocker releases the lever and allows it to move away from the gear nut. The lever has an opening that is somewhat bigger than a pin on the cam that extends into the opening. When the pin reaches one surface of the opening, it pulls the lever out of its engaged position.

Furthermore, an impact which occurs when the adjusting bolts and the table come into contact with each other is attenuated by shock absorbers which are respectively mounted on said stopper members.

The default value is relatively high compared to the expected range of actual vehicle gross combined weight. Large skip upshifts, greater than 50% ratio step, are prohibited after a reset until the control parameter value is verified.
