Patent FR-2456303-A1 (FR)
Inventor: BILLOTTET HENRI
IPC: F41A23/34
Filed: 1979-05-08
Abstract: Carried weapon system with a high orientation mobility in elevation and bearing. The elevation mobility is ensured by eliminating the turret and the provision of a shaft in the vehicle superstructure in accordance with its longitudinal axis and the fixing of the weapon to its cradle in said shaft which is open towards the top and front and beneath the weapon towards the bottom. The mobility in bearing is ensured by the self-rotation of the vehicle which displaces the weapon. Such movable turretless weapon system is able to fire at land, maritime and air targets.

Title: Joystick for regulating colours of TV receiver - adjusts blue intensity independently of red and green which are inversely adjusted relative to one another
Inventor: CARMONA GEORGES
IPC: H04N9/20
Filed: 1979-10-25
Abstract: The device comprises a manually operated joystick type control lever (27) which passes through elongate slots in two stirrup bars (31,32) orientated perpendicular to one another such that movement of the lever in the X-Y and Y-Y directions moves a respective one of the bars independently of the other.

Title: Flame cutting gas upgrading - by automatically controlled admixture of liq. hydrocarbon mixt.
IPC: F23K5/00
Filed: 1980-02-05
Abstract: Calorific value, flame velocity and ignition temp. of gases used in flame cutting operations are improved by adding a liq. hydrocarbon mixt. in a fixed ratio.
