Patent FR-2301660-A1 (FR)
Title: Hot air circulation flue - consists of metal horizontal and vertical compartment extending behind and below fire and incorporating baffle plates
IPC: F24B1/188
Filed: 1975-02-20
Abstract: The flue consists of two heating surfaces (1, 2) with an anti-backfow plate (3). Fresh air for combustion is discharged through a hole (7) which is regulated by a flap (3). A pre-heating flap (23) enables the fire to be lit without smoke, by stuffing paper between the plates (23, 2). Baffle plates (8) placed at right angles to the direction of air circulation in the horizontal and vertical compartments help to raise the air temperature. The ambient air enters through (4) and flows along the baffle-plates (8) until it escapes through two holes (6).

Title: Plasma torch nozzle - cathode for longer service life - by time relay inserting load resistors in transductor circuit
IPC: H05H1/36
Filed: 1975-03-18
Abstract: The service life of the nozzle and of the cathode of a plasma cutting torch with transductor control can be increased by loading the transductor after completion of the cutting operation for a time of over two periods of the operational frequency with a much smaller (5%) current than the max. permissible load current. A time relay is used to introduce load resistors into the transductor output circuit. This eliminates the high starting current peaks caused by the remanence of the transductor cores. The plasma torch can pierce holes in quick succession without damage to cathode or nozzle. The system combines the advantage of little instrumentation with that of a high power density of the plasma arc.

Title: Projectile launching tube with booster charge - has main charge in inner tube and booster in outer tube, with partition between them
Inventor: GUILLOT JEAN
IPC: F41A1/08
Filed: 1975-07-21
Abstract: A hand held projectile launching tube has two tubes made of fibre reinforced plastics material, the inner tube (4) able to slide inside the outer (1). The inner tube has a partition (8) across its rear end so that a launching charge (6) can be inserted between it and the projectile (5). A booster charge (9) is then positioned on the other side of the partition. This latter charge is contained in a casing (7) which fits inside the overhang of the outer tube. It can be ignited electrically by pressing a trigger on the outer tube so that the main charge and the projectile are propelled forwards. After a short while, the main charge is ignited, so that the projectile is ejected at great speed. The telescopic movement of the two tubes ensures a recoilless action.

Patent FR-2346139-A1 (FR)
Title: Appts. for blending and dispensing a liquid resin and foam mixture - using volumetric pumps to draw from the liq. reagent containers
IPC: B29B7/74
Filed: 1975-10-03
Abstract: Appts. for blending liq. resin with a foamed carrier and discharging the resin impregnated foam via a nozzle, where self-priming pumps draw resin and liq. foaming agent from their respective containers via filers and deliver the reagents to the in line and offset branches of a blending head resembling a 45 degrees side entry pipe junction fitting. The resin is injected via a solenoid valve just upstream from a junction with an input line for a rinse liq., pref. pressurised water. The foaming agent is mixed with pressurised air prior to entering the blending head where it is heated and passed through a sponge block before impinging on the resin path through the blending head. The resin laden foam is discharged via a flexible adaptor and hose to a spray nozzle for applying the foam as required. The equipment is made from simple components. No intermediate resin or foam reagent storage vessels are involved. The volumetric pumps can be driven from a common motor and their delivery is less susceptible to variation than more viscosity-dependant systems, i.e. press. or flow rate control systems. The resin is distributed effectively by the turbulence generated in the foam stream at the point where the latter changes direction wh ile passing through the blending head. The flexible components downstream of the mixing point can be flexed to displace any stagnant deposits.

Title: Bridging contact for heavy current switches - is esp. for rotary types with contact maintained by annular springs
Inventor: BAULIER HENRY
IPC: H01R13/631
Filed: 1976-06-22
Abstract: The contactor system is for switches handling high current levels esp. switches having a rotary action but is also applicable to switching arrangements which have one conductor moving along the axis of a second fixed conductor. Both forms use a pair of conductors to bridge the conductor gap. The conductors are curved presenting a concave surface to the interior of the switch.

Contact pressure is maintained by a spring such that the corners of the bridging conductors bear against the surface of the main conductors.
Patent FR-2315643-A1 (FR)
IPC: B65H75/42
Filed: 1976-06-22
Abstract: The invention provides a latching mechanism including a pawl, a ratchet wheel having a recess engageable with the pawl to restrict rotation of the wheel in one direction and cam means associated with the wheel and operative on rotation thereof in said one direction to urge the pawl away from the recess. The pawl is biased solely by gravity to move toward the recess whereby to enable engagement in said recess. The gravity bias acting on the pawl will be insufficient to cause the pawl to be in a position to engage said recess when the angular velocity of the wheel is in excess of a predetermined latching velocity. The latching mechanism may be used in a winding apparatus for hose.

Title: Hollow ceramic brick screw press - uses shaping tool to give peripheral expansion in region of laminar flow
IPC: B28B3/26
Filed: 1977-05-12
Abstract: Plastic partic, ceramic substances are shaped on screw presses pref, into hollow bricks. Expansion is imported at the periphery in the region of laminar flow by means of a shaping tool (2, 3) according to relative elastic expansion of the substance of which the extent is reached at the periphery of the blank. The shaping tool is mounted on a base plate (1) and consists of a shaping member (2) and mouthpiece (3). The circumference of the shaping zone, begining at the inlet (e) of the shaping member increases gradually to the outlet (a) at the mouthpiece by the length of elastic expansion of the ceramic substance. Differences in elastic changes in length are thus reduced or eliminated to ensure constant shrinkage in different areas of the blank.
