Title: Construction of concrete pillars by assembly and superposition of plastic components forming permanent formwork
IPC: E04C3/34
Filed: 1986-01-08
Abstract: The invention comprises two types of rigid plastic components to be assembled without tools and for forming elements to be superimposed for building pillars. The two basic components are: a. A square component with a side of approximately 6 cm and a height of 25 cm, comprising two grooves in the height direction 1 and 2, a notch 3 and an orifice 4 at each end; b. A rectangular component approximately 23 cm wide, 25 cm high and 2 cm thick, comprising two projections 5 and 6, a decorative face 7 and a grooved face 8. By assembling four components a and four components b a square element is formed with a side of approximately 32 cm. Several superimposed elements, joined together by iron elements inserted in the orifices 4 and held rigidly by iron wire attached to the connecting iron elements inside the notches 3, form decorative formwork elements. The device, according to the invention, is more particularly intended for building reinforced concrete pillars.

Title: Subsea fair
IPC: A63G3/06
Filed: 1986-10-01
Abstract: Funfairs in the world are inspired, for the most part, by spectacular events which take place on the planet in order to make them into public games; only the subsea domain has escaped this; the gap is now filled. The fair proposed by the present patent uses gondolas 3 made from two interlocked parts which, once charged with their passengers, are submerged by towing cables and displaced over a subsea path supplemented with spectacular scenes relating to the medium. The star turn of the spectacle consists of the successive return of the gondolas 2 to the surface which, under the effect of the upthrust, takes place in a gush of foam. The commercial characteristic in this fair is its high profitability due to the high turnover which it allows, from 1000 to 1500 passengers/hour.

Filed: 1987-08-07
Abstract: Gear whose diameter can be adjusted as a function of the torque. Toothed wheel device with variable diameter composed at its centre of a pin 9 interacting with a cone 4 which, by axial movement, acts on the rods 3 themselves acting on the shoes 5 thus causing the diameter of the device to vary. The ring 6 holds the rods 3 whilst allowing them to move radially. A chain 1 representing the teeth of the toothed wheel is at a fixed point at one of its ends 1a and in the figure it can be seen that the other end is hooked onto the spring 2. The gear 13 connects the movement between the chain 1 and the rod 3a by means of the rack 15 and of the set of gears 14. The instantaneous diameter results from the equilibrium of the tangential load given by the gear 37 to the chain 1 and the axial force exerted on the cone 4.
