Patent FR-2621383-A1 (FR)
Title: Advertising keyring lighter
IPC: A44B15/00
Filed: 1987-03-05
Abstract: The present invention relates to a novel design of advertising keyring lighter relating to motor sport. The operating device has been designed so as not to change the overall shape of the car, and thereby allows the wing to be used to move the mechanism. For the quartz system it is necessary to press on the wing in the backwards direction towards the front of the car. The quartz mechanism is housed in the base of the wing. The latter moves in guiding slideways provided at the back of the scale model. During its travel the tenons of the wing actuate a pivoting fork, which triggers the opening for the gas causing the nozzle to move forwards in its pressure-reducing device, before the quartz is triggered. At the end of its cycle the quartz sends its spark from the tab towards the nozzle and lights the lighter. The flame is ducted by a piece of stainless steel clipped over the whole of the rear of the car. The fact of releasing the pressure on the wing means that the spring of the quartz returns the assembly backwards, cutting off the gas by means of the fork. The quartz system and the nozzle and pressure-reducing assembly are already used by some manufacturers and are mounted with their agreement. The gas reservoir is housed in the body of the car, between the front axle and the back axle.

Inventor: BOUCHIER GUY MARCEL JACQUES
IPC: H05H1/34
Filed: 1987-02-19
Abstract: In a device of the plasma scalpel type (40, 41) including at least two spaced-apart electrodes (21, 22) subjected to electrical potential differences such that electric arcs take place therebetween, together with structures for producing at least one fluid flow passing through a region of space where said electric arcs occur, the potential differences being alternating potential differences at medium or high frequency, the ends of said electrodes are substantially filiform and forming an angle therebetween which is preferably acute, and a voltage step-up transformer is incorporated therein in order to deliver the alternating potential differences, with the fluid flows arriving from within the angle or along at least one of said electrodes. In one embodiment, each of the electrodes is constituted by a wire of electrically conductive material (21, 22) and is placed inside an electrode-carrier duct (27, 28) whose inside diameter is slightly greater than the diameter of the electrode, with the end of the electrode projecting beyond the duct and with the fluids being conveyed along said electrode-carriers. The device is versatile. It has numerous applications, in particular in dental surgery, but also for operations of etching, cutting out, welding, or recharging with material, treatments to composite materials, etc.
