The method involves providing a protection device (205) for compressing a carrier drum (203) against a machine roll (204). Mechanical vibration of the drum is measured using a speed sensor. A direction of a radial component of nip force (Fn) between the drum and the machine roll is changed relative to a part of the protective device as a stopper by changing a rolling angle (alpha) between the drum...

A high efficiency fluid power transformer is applied generally and particularly to continuous application where efficiency gain is important, that of an underwater wave energy converter, WEC, that reciprocates as recurring waves pass over. Single acting, double acting and helical hydraulic actuators pressurize hydraulic fluid in an energy conversion system. Ultimately, the energy conversion system...

A dynamic rod implantable into a patient and connectable between two vertebral anchors in adjacent vertebral bodies is provided. The dynamic rod fixes the adjacent vertebral bodies together in a dynamic fashion providing immediate postoperative stability and support of the spine. The dynamic rod comprises a first rod portion having a first engaging portion and a second rod portion having a second ...

The invention relates to a support (1) for non-definitively fixing a temporary crown (8) of one or several teeth to a pillar (3) which is in turn fixed on a dental implant (4) inserted into the bone structure of the patient, and which has additional means for clip retaining to said pillar (3) and mechanical retaining elements (9, 10, 11) preventing both the axial and rotational movement of the tem...

A device for detecting the condition of flow in a respiration system combines the function of a nonreturn valve with the function of flow measurement in a common device. The device includes a valve arrangement (1) with a valve disk (9) and with a valve body (8), wherein the position of a valve disk (9) in relation to a valve seat (11) is detected. An indicator for a flow and a direction of flow (5...

A fiberglass pipe-shaped insulator and a method of manufacturing the same are disclosed. The high-density fiberglass pipe-shaped insulator is manufactured by preparing a fiberglass needle mat formed at opposite sides thereof with cutting faces at unaligned positions, at least one surface of the fiberglass needle mat being coated with a binder prepared by mixing and agitating organic and inorganic ...

A receptacle (10), e.g. a jug, comprising a flat or substantially flat base wall (16), a sidewall (18) extending upwardly from the base wall (16) to define a liquid receiving volume (12), and a plurality of integrally-formed projections and/or indentations located on the sidewall (18) arranged to indicate, in use, the depth of liquid within the liquid receiving volume (12). The receptacle may be m...

The invention relates to a process for marine seismic exploration at least two different depths by means of streamers, each including a set of hydrophones, the acquisition of data at the different depths being performed in a single exploration region, and in which the position of the streamers and the hydrophones when acquiring seismic data at a first depth is independent of the position of the st...

A control device for an automatic reset apparatus has a plurality of electromechanical units, each electrically connected to a phase of an electrical system. The electromagnetic units are kinematically connected to an actuation mechanism of a microswitch that drives an electronic control device of a reset apparatus associated with a protection device of the system. Each of the electromechanical un...

A mosquito net having a net (1), suitable to be suspended and a support (6), characterized in that said support is substantially shaped like a rod, having a first end (7) in correspondence of which the support has a stiffness that is substantially greater than at a second end (8).

A mosquito net having a net (1), suitable to be suspended, a frame formed by a first structure (3) fixed to said net, and a second structure (4) suspended from said first structure by means of a plurality of stays (7). A frame component for a mosquito net.
