Title: Spindle revolution electrical monitoring appts. for ring spinning frame - comprises spindles driven by separate electric motors attached to generator sending impulses on=line to analyser for indicating spindle stoppage faults
Inventor: STAHLECKER GERD
IPC: H02K11/225
Filed: 1992-05-06
Abstract: The spindles (23) are driven by separate motors to which is attached a form of generator to send impulses along a line to an analyser (4). The power supply line (5) is pref. three-phase current to separate motors and spindles (23). Pref. induction motors, which have stator and squirrel cage rotor have a coil (2) fitted close to the end of the rotor, and to lie between two armature slots, so a current is induced into the coil, forming a pulse generated current, connected to a diode rectifier (7), and to a line (6) running to an analyser (4). The pulses form each motor and spindle are timed to appear in sequence, and the absence of a pulse in a specific region may indicate an inactive motor with, spindle stopped. Pref. synchronous motors have an overload to stop the motor. A permanent magnet is attached to the spindle near the bottom bearing in the motor, and is alligned to the coil which generates a pulse signal, which is fed to the analyser (4) similarly. A circuit in the analyser may produce the alarm signal. USE - Each spindle is monitored electrically to ensure it is running, and there are connections to alarm appts. so a fault may be rectified.

Patent DE-4316816-A1 (DE)
Title: Circuit arrangement
Inventor: FRANKE WALTER DIPL ING
IPC: H03K17/12
Filed: 1993-05-19
Abstract: If an individual converter valve cannot be loaded on its own - in particular at high switching frequencies - with the necessary (high) current, two or more converter valves must always be interconnected in parallel. Owing to component-related scatter, structurally identical power semiconductors have characteristics which are different from one another in practice. Consequently, currents of different magnitude flow through them at the same saturation voltage.   In order that the currents are divided as uniformly as possible, two converter valves, for example two IGBTs (I, II), are operated in two parallel line branches (1, 2), line sections, which are wound in the opposite winding direction (with the same number of turns) over a common magnet core to form windings (L1, L2), being connected upstream of the converter valves. The difference between the saturation voltages is divided equally between the two windings (L1, L2) in the case of pulse-clocked converter valves. Approximate balancing of the currents can be achieved in this way. <IMAGE>

Patent DE-4406264-A1 (DE)
Inventor: NORBRON THOMAS WILLIAM
IPC: A62B25/00
Filed: 1994-02-25
Abstract: A quick-fire release device for emergency escape breathing apparatus which initiates the flow of breathable gas from a gas storage device 7 to a hood 15 on opening the pack in which the apparatus is stored. A cord 20 is wrapped twice around a cord winding section 24 of a handwheel 9, which opens and closes a valve which controls the flow of gas to the hood 15. The handwheel 9 also has a disk portion 26 which is of a larger diameter than the cord winding section 24; close to the circumference of this disk portion 26 is a snap-in holder 30, 31, 35 through which the cord 20 passes before being attached to the openable lid 2 of the pack. Because the disk portion 26 is of a larger diameter than the cord winding section 24 the handwheel 9 initially rotates slowly as the pack is opened by unfastening its closure portion 2 from its storage portion 3, and the cord 20 unwinds from the snap-in holder, and then rotates more quickly as the cord 20 unwinds from the cord winding section 24. <IMAGE>
