Patent FR-2266976-A1 (FR)
Title: Control circuit for induction motor - has thyristor circuit forming induction motor braking
IPC: H02P27/02
Filed: 1975-04-02
Abstract: A device generates triggering pulses applied to four thyristors. Logic switching means detect when the speed of the controlled motor is less than the instantaneous rotational speed of the induction motor and transmit an authorization signal to the generators. Means detect instantaneous current intensity in a phase of the induction motor stator winding. This current intensity is then compared with a predetermined reference current and a resulting differential control signal is sent to the generator. A synchronising voltage in phase with the voltage of thyristors is sent to the generator so that when the generator receives the authorization signal the trigger pulses, which are a function of the differential control and synchronising voltage, are applied to the thyristor to send a unidirectional current through the stator windings so as to effect dynamic braking.

Title: Frame for rigid dirigible airship - has staggered polygonal frames with short struts to prevent buckling
IPC: B64B1/08
Filed: 1975-10-31
Abstract: The frame for a rigid dirigible airship is built up from a large number of polygonal frames (10) with sides (12) placed side by side along the length of the airship. Adjacent frames are staggered so that a vertex of one polygon is in line with the mid point of the sides of adjacent polygons.
