Patent FR-2233209-A1 (FR)
Title: Curve compensating three bogie rail vehicle - centre bogie is displaced on curves by arms on outer bogies
IPC: B61F5/46
Filed: 1973-06-14
Abstract: The centre bogie can be displaced both vertically and laterally on curves, under control of the outer bogies. Displacement is effected by a gear system operated by toothed segments at the ends of arms fitted to the outer bogies at their inner ends. The gear system consists of two pinions, each engaging with the toothed quandrant connected to an outer bogie and another toothed sector solid with the vehicle body. The body is pendular suspended and the control affects both lateral and vertical displacements according to the severity of the curve being negotiated.

Title: Transfer mechanism for delicate pressing blanks - has program operated table with movements along two mutually perpendicular axes
IPC: B65G47/90
Filed: 1973-11-28
Abstract: The transfer mechanism is used for transferring delicate components such as compacted carbide powder components in the pressing machine. These components must be placed down carefully without damage. The delicate components are picked up in a particular version by means of a rotating transport arm with a suction head. These components are picked up from a press and placed on the transfer table. The arrangement has a table which is able to move along two mutually perpendicular axes. the object is transferred by the transporter arm. The components are stacked on the table in a number of layers. For this purpose the arrangement has a pneumatic drive for actuating the table and the disc in axial direction. the control disc has a number of position marks on concentric circles and the linear markings specify the particular circle. The scanning element senses the rotation of the control disc. The scanning element actuates the pneumatic driving elements.

Title: Waste edge strips cut from a woven web - are wound onto a support rotating about two non-parallel axes to produce a cross wound package
IPC: B65H54/56
Filed: 1974-03-20
Abstract: A waste edge strip cut from a woven fabric formed on eg a loom using a water jet to pick the weft is taken up downstream on the loom reed on pref a conical bobbin which is pref rotatably mounted by a spindle on a cranked arm extending radially from a boss which is freely rotatable on a shaft. A driven pulley on the shaft is pref. biassed against the boss to rotate it and cause the cranked arm to orbit around the shaft and as the arm orbits pref a crown wheel on the spindle pulley co-operates with a fixed gear on the shaft to rotate the bobbin spindle. The bobbin then rotates about the non-parallel axes and the edge strip is formed into a cross-wound package on the bobbin whereby more of the strip can be wound onto a bobbin and bobbin doffing operations are reduced.

Title: Restarting cold blast furnaces - using lance comprising coaxial tubes providing oxygen surrounded by fuel stream
Inventor: WELLS WILLIAM
IPC: C21B5/00
Filed: 1974-06-19
Abstract: Blast furnace which has gone cold is restarted by inserting in the iron notch and cinder notch a lance comprising inner and outer tubes with a space between, sealing the lance in each of the notches, injecting an O2 stream into the furnace through the inner tube and injecting the hydrocarbon fuel through the space between the tubes so that the hydrocarbon surrounds the O2 stream. The fuel/O2 ratio is varied so that the burden in the furnace is heated and then the cold iron is oxidised, the exothermic reaction occurs to raise the iron and slag to liquefying temps. and the lances are removed from the notches and the blast restored to the furnace. Restarting is rapid and lances do not tend to burn back whilst inserted in furnace. Tuyeres are left undamaged and break-outs are minimised.

Title: Three-dimensional woven fabric - formed by alternately picking two wefts in mutually perpendicular directions in zig zag warp layer
Inventor: RAPIN MICHEL
IPC: D03D25/00
Filed: 1975-07-31
Abstract: The fabric is produced forming a layer of warp yarns into a zigzag configuration by e.g. passing them around upper and lower rows of parallel bars so that the warp yarns extend in a first (e.g. vertical) direction. Spacer elements are provided in second and third directions perpendicular to the first direction forming e.g. a grid so that two weft yarns can be woven alternately into the warp in both the second and third directions, without frictional contact between the weft yarns and the warp yarns. The fabric is used as an insulator and has good resistant to shock and abrasion. Because the two weft yarns are woven alternately a more uniform fabric is produced.

Title: Monometer assembly for pressurised HV appts. - has ball valve preventing gas leak when monometer is removed for servicing
IPC: H02B13/045
Filed: 1975-11-10
Abstract: The manometer assembly, for HV equipment containing pressurised gas, avoids releasing gas when the manometer is removed or serviced by using a small ball valve. The manometer (24) is connected to a rod (38) whose lower end carries a ball (16). When the assembly is working the ball allows gas in the HV equipment (10) to pass through a hole into the space (26) occupied by the manometer. When the manometer requires servicing the cover (32) beneath which it is fixed is drawn upwards (the seal being maintained by a sealing ring (36) until the ball seals the gas inlet hole. This sealing takes place before the cover is removed completely, so no gas escapes from the HV equipment.

Title: Chemical reactor for two immiscible liquids - has emulsifier, e.g. using ultrasonic waves, at inlet replacing mechanical agitators
Inventor: RAYMOND BERNARD PIERRE-MARIE
IPC: B01F3/08
Filed: 1976-01-16
Abstract: Physical/chemical reactions are initiated in a processing vessel, by bringing together >=2 immiscible fluids. The fluids are introduced via a common conduit into an emulsifier at the inlet of the reactor. Inside the reactor the fluids are pref. recirculated by means of the jet leaving the emulsifier. Baffles are also fitted to guide the flow. A number of reactors in tandem, may be located at the inlet of each of which there is an emulsifier of the vibrating blade type, fed by a pump in the fluid line. Use of vane and screw agitators, etc. which, apart from a certain inefficiency, consume a large amt. of energy, is avoided, and the only maintenance required is cleaning.

Title: Girdle-type tyre - with two-ply girdle reinforced with steel wire cords
Inventor: PECENKA PETER
IPC: B60C9/26
Filed: 1976-08-18
Abstract: The plies are reinforced by cords running parallel to each other, and the side parts of one ply are wrapped round the side parts of the other. Th eply reinforcing cords are of steel and enclose the same angle (alpha) where they cross the tyre meridian. Redn of the side forces in the tyre is obtd; the side zones of the girdle are so strong that the cord direction in the wrap over and covered ends of the two plies need not be the same. This simplifies the tyre construction technique.
