Patent FR-2270648-A1 (FR)
Title: AC safety cct for industrial use - has transistor alternating between saturated and blocked condition under astable multivibrator control
IPC: B61L1/18
Filed: 1974-05-10
Abstract: The circuit comprises a transformer (1, 2, 3) with the secondary connected to a diode bridge with a load resistance (4) in series and a short-circuiting relay (5) across one diagonal of the bridge. The other diagonal is strapped between the emitter and collector terminals of an NPN transistor which functions as an interrupter. The base and emitter terminals are connected across the output load circuit (8) of an astable multivibrator, which incorporates two PNP transistors operating in the non-saturated condition. The circuit functions by multivibrator signals causing the NPN transistor (7) to be alternatively saturated or blocked. During the saturated phase the polarised relay (5) short-circuits the bridge.

Title: Corrugated cardboard manufacture - involves corrugating rollers with mutually skew axes for noise reduction
IPC: B31F1/28
Filed: 1974-06-27
Abstract: Single-sided corrugated cardboard is produced by corrugating a length with two rotary corrugating rollers and sticking the cover length to the crests. The undulation of the two rollers interengage and are at 90 deg. to the side edges of the length to be corrugated. The long axis of the first roller is skew to that of the second, in order to reduce noise. Preferably a force is applied to the ends of the first roller, so that the surface in contact with the second roller is concave. The angle of skew is 0.3-3 deg. The appts. has a hollow metal corrugating roller of length at least five times its av. dia., and with peripheral corrugations which are at 0.2-3 deg. to the long axis of the roller. The roller is barrel shaped to compensate for bending under the working load.

Title: Shock absorbing safety barrier for roads - has collapsible curved outer barrier with inner folded strip
IPC: E01F15/04
Filed: 1975-05-09
Abstract: The barrier is intended for use at traffic islands. The outer part of the barrier is a curved strip (14) supported by posts at each end.
