Title: Improved laterally retractable stair
Inventor: LOUIS SOULARD
IPC: E04F11/06
Filed: 1991-04-24
Abstract: The invention relates to an improvement aimed at facilitating the use of a laterally foldable stair. The device will consist in mounting, for the upper step, a normal step (7) totally independent of the foldable element, which will avoid widening the tread for an articulated step which would otherwise abut against the bottom of the well. Supported by the walls of this well, (7) will be able, for a necessary clearance, either to have width reductions (8) at one end or be mounted pivotably on the side opposite the wall. In the version with steep inclination, with alternating omission of half-steps, (7), reduced to a half width, will be fixed or will pivot on an axial inverted console. Closure will be effected from the floor, by acting on the pedal (19), lifting the central post and folding, by way of the cable (10). This device will avoid an unnecessary elongation of the batter and will facilitate the manoeuvring of the stair at both levels.

Title: Electric barrier device of the rake (harrow) type intended to control entry and exit of vehicles in selective-access premises
Inventor: JEAN LEDIEU
IPC: E01F13/12
Filed: 1991-08-02
Abstract: The subject of the present invention is an electric barrier device of the rake type intended to allow free entry and controlled entry and exit of vehicles in selective-access premises. The rake is equipped, over its entire length, with a shaft (1) fitted with a lug (2) intended electrically to control the retraction of the teeth of the rake (3) into the structure (4) by the action of a motor (5) in order to allow controlled exit of vehicles. The teeth of the rake are held in a semi-vertical position by the addition of a return spring. The inclination of the teeth will be such that they will inflict severe damage to the tyres of the vehicles violating the barrier when leaving, while they can be retracted freely and independently of one another for any entering vehicle. The rake may be equipped with a manual device for retracting the rake using a key or a small crank in order to remedy the absence of motor force. The rake may advantageously benefit from a de-icing device acting by electrically heating the rake during bad winter weather.

Patent FR-2684720-A1 (FR)
Title: Exhaust device for an internal combustion engine
Inventor: IKENOYA YASUO
IPC: F01N3/04
Filed: 1992-12-07
Abstract: A control unit 12 is designed to control the opening and closing of a water-injection valve 11 fitted to a water-injection pipe 10 which is connected to an exhaust pipe 2. The control unit 12 produces the signal for opening the valve under conditions which are predefined as a function of the rotational speed N epsilon and the degree of opening theta TH of the stopper, which are input respectively from a rotation sensor 8 and a stopper sensor 16, and opens the injection valve 11 to allow the injection pipe 10 to inject water into the exhaust pipe 2. The injection of water into the exhaust pipe 2 serves to lower the temperature of the gases in the exhaust pipe 2 in order to bring the pressure pulse conditions back into harmonic conditions. Consequently, the drop in power delivered in the low and medium-speed ranges may be corrected and at the same time the longevity of the sensors as well as their response may be enhanced by measuring the degree of opening theta TH of the stopper.
