Patent ES-396441-A1 (ES)
Title: Automatically resettable fire sprinkler valve
IPC: A62C37/08
Filed: 1971-10-27
Abstract: An automatically-resettable fire sprinkler valve is normally held closed by a piston-cylinder unit in which both ends of the piston are exposed to the high main-supply water pressure, one of the piston ends being of greater effective area than the other, such that the same water pressure acting on the different end areas normally forces a valve member to a flow-blocking position. A normally-closed bleed port associated with the broader-area end of the unit is valved open to a pressure-relieving condition by mechanical response of a thermal actuator to temperatures above a predetermined critical level, whereby the sprinkler valve is forced open by the main-supply pressure when the temperature decreases to a safe low level, the bleed port is automatically closed by the thermal actuator, and equal pressures on the unequal-area piston ends cause positive reclosing of the sprinkler valve.

One of the two holders (19) is a thread clamp, whilst the other holder (20) is designed as a deflecting web for the tension thread (18). The thread clamp (19) is spring-loaded in the tensioning direction, and, at each point along its adjusting travel, it can selectively be released and moved back into its initial position together with the other holder (20). The apparatus works absolutely reliably at a low outlay in terms of construction. It can insert a tension-thread loop at any desired point on the fabric, whilst all the thread loops can be interconnected and can subsequently be drawn out of the fabric in an interconnected manner.

Title: Stranding machine
IPC: B65H59/04
Filed: 1980-12-12
Abstract: In a stranding machine comprising a plurality of aligned, hollow shafts each having a pair of bobbins rotatably mounted thereon (one such shaft 5 and one of its bobbins 8 being shown), one bobbin of each pair being used for stranding whilst the other is winding up fresh wire and then the roles of the two bobbins being exchanged, a braking means (not shown) is provided to regulate the tension in the wire 2 as it is drawn from the stranding bobbin and guided into the hollow shaft 5 through which it is drawn to the stranding station. Thus, the wire passes over a pulley 41 carried by a lever 36, the movement of which under the action of the wire tension (opposed by a spring) is used to regulate a braking force on the bobbin 8. As the machine stops and the consequent reduction in wire tension is sensed, maximum braking torque is applied to the bobbin 8. For use of that bobbin in the next phase (rewinding) the brake is readily disengaged altogether.
