Patent FR-2147128-A1 (FR)
IPC: E05F1/00
Filed: 1972-07-24
Abstract: 1376735 Fire-operated doors and windows TELEFLEX Ltd 18 July 1972 [23 July 1971] 34794/71 Heading A5A [Also in Divisions F2 and G1] A temperature sensitive actuator 16 for automaticaly operating a door or window installation 11 in the event of a fire comprises two rotary members 24, 25 (Fig. 3) separated by an energy storage spring 28 and an epicyclic year train, the rotary members 24, 25 and spring 28 being assembled to be rotatable conjointly except in the event of a fire when the rotary members 24, 25 are caused to rotate relative to one another by the action of the spring 28. As shown, the actuator 16 is inserted in a drive cable 10, 17 to a window installation 11 from a manually operable window opening and closing mechanism 12 in such a way as to provide a direct drive between the mechanism 12 and installation 11 except in the event of a fire when the actuator 16 automatically causes the window to close. The cable lengths 10, 17 which each comprise a relatively movable core and casing are connected respectively to an input wheel 24 and output wheel 25 of the actuator 16, the input wheel 24 being integral with a gear ring 27 which meshes with planet gears 31 carried by the output wheel 25. A spiral spring 28 which is fixed to the wheel 24 at its outer end is attached at its inner end to a spindle 29 which supports a sun wheel 30 meshing with the gears 31. The spindle is so connected by fusible plugs 34 to a tube 33 carrying the output wheel 25 that under normal temperature conditions the wheels 24, 25 are rotatable conjointly and maintain the spring in an energy stored condition. When, however, the plugs 34 fuse upon being subjected to an elevated temperature either directly by the action of a fire or by a heater 36 operatively connected to a smoke detector, the spring 28 releases its stored energy to cause the wheel 25 to rotate relative to the input wheel 24 and thereby close the windows 11.

Title: Sodium prodn eg from sodium carbonate and coke - with condensation of sodium vapour by a highly effective indirect heat tra
IPC: B01D5/00
Filed: 1972-10-17
Abstract: Na is produced, e.g. fro m Na2CO3 and coke, providing a CO/Na mixt., by condensing the Na vapour on one side of, and allowing non-condensible gases to pass through, the heat exchanger. The condensed, liq. Na is then fed to the second side of the heat exchanger by a press.-relief valve, where there is a lower temp. and press., but sufficient to discharge the Na. Part of the driven-off Na vapour is removed and the second portion is passed to a Na condenser/water evaporator where the Na condenses to a liq. and the heat released forms steam. The liq. Na is then returned from the evaporator to the second side of the heat exchanger.

Title: Extruded resin coating - using die with projections enclosing slot to reduce shrinkage
IPC: B29C48/08
Filed: 1972-10-31
Abstract: Reduction of shrinkage in an extruded resin coating is effected by using an extrusion die with projections enclosing a slot connected to the channel, of the die, and by reducing the free space between the lower surface of the die and the surface of the sheet to be coated. Specif. the extruded resinis polypropylene or polyethylene with a density of 0.950-0.970g/cc. The distance between the surface of the sheet and the ends of the projections is 20-70% of the total distance between the surface of the sheet and the lower surface of the die, excluding the projections.

Alternatively two spaced reinforcing webs may be incorporated in the fabric are pref. covered with a protective film (e.g. polyethylene PVA, paper or reconstitutes cellulose) and a dispersion of granular adhesive resin (e.g. polyester) may be incorporated in the partially polymerised resin. The fabric may be needled to push the glass fibres through the reinforcing web. The fabric has a reasonable elasticity in both longitudinal and transverse directions and can be easily worked. The fabric may be used as a reinforcing ply in a moulded article.

Title: Cushioning articles prodn. - by foaming inside prepd. laminar plastic and fabric bags
IPC: B68G7/00
Filed: 1974-02-12
Abstract: Cushioning, with an outer envelope of sealing film and a fabric or plastic material, is made by forming an enclosed bag with an opening for filling with foamable material before its expansion, placing this bag in a two-part foaming mould connected to a vacuum, filling and foaming the interior, releasing from the mould and closing the bag over the expanded contents.

Title: Fastening rails on sleepers using spring clips - by using jacks to exert temporary holding down pressure on inner parts of clips
IPC: E01B9/48
Filed: 1975-02-27
Abstract: Flat-bottomed rails are attached to sleepers using sprung clips, the inside parts of which press on the corresponding rail flanges while the outside parts press on the sleepers, the necessary pressure being supplied by a sleeper-screw or spike. Before the final tightening of the screw, temporary pressure is exerted on the inside parts using any appropriate apparatus controlled by hydraulic pneumatic or electrically operated jacks and supported on a wheel-mounted chassis which preferably runs along the rails being fixed. This brings the inside parts of the clips into direct contact with the rail flanges. This pressure is then maintained by the final tightening of the screws acting on the outside parts of the clips.
