Title: Rotary knife for cutting off plastic tubing - activated by an electromagnetic lever on a rotary collar
IPC: B26D1/28
Filed: 1973-12-07
Abstract: Pipe or hose cutting device comprising an annular collar for surrounding the hose section and rotating together with a floating collar supporting a radial shaft aligned with an electromagnet. A second shaft diametrically opposite the first is associated with a counterweight to the magnet. The cutting knife is mounted on a cranked arm attached to the first shaft and to an intermediate pivot. Activation of the magnet moves the shaft and hence pivots the knife into a cutting position. The movement shifts the position of the counterweight. When the electromagnet is de-energised, the counterweight reassures a dynamic balance position, thus automatically disengaging the knife from the pipe profile. The appts. for cutting thermoplastic pipe into specific lengths, is of compact design with a minimal number of moving parts and provides a precise, reproducible cutting locus.

Patent FR-2245112-A1 (FR)
Title: Small motor with slot frequency noise reduction - is by uneven gaps between curved stator magnets and wound rotor and housing
IPC: H02K23/04
Filed: 1974-09-23
Abstract: The micromotor has the induction between the inner surfaces of the stator curved poles and the outer surface of the wound, cylindrical rotor decreased progressively towards the ends of the stator poles by increasing the gap between stator and rotor in these directions. Increasing the gap in this way enables permanent stator magnets of higher strength or energy density to replace weaker magnets without causing noise. The same result may be achieved by tapering both the inner and the outer curved surfaces of the stator magnets so that the gaps between magnets and housing and between magnets and rotor increase towards the ends of the magnets. Alternatively, the magnets may have a uniform cross-section and the housing may be elliptical so that the gap between magnet and rotor is constant but that between magnet and housing increases as before.
