Patent FR-2243913-A1 (FR)
IPC: E04B/
Filed: 1974-03-25
Abstract: The invention relates to a fire screening glazing panel and a method for forming the panel. The panel is composed of at least two structural plys, at least one of which is a vitreous sheet, and a layer therebetween composed at least in part of a heat convertible carrier forming material which material forms a solid porous or cellular thermally insulating body when subjected to sufficient heat, as during a fire. A protective stratum is applied to at least one of the vitreous sheet plys for inhibiting interaction between the barrier forming material and the ply, thereby maintaining the transparency of the ply if it is formed of transparent material, and maintaining its color.

Patent FR-2310646-A1 (FR)
Title: Underground cable splice operated by fluid pressure - has tapered jaws preloaded by spring and made to bite cable by piston
IPC: H02G15/18
Filed: 1975-05-09
Abstract: The end of the cable (42) is manually inserted into the opening (6) through the jaw-cluster bore and into the cavity (26) until the end of the cable engages the abutment (28). A like procedure is followed for the other cable. As each cables is installed, the respective springs (34, 34a) will compress, allowing the jaws to move axially and radially, so that the jaw cluster bores open up to receive the cables. When the cables are released, the forces of the springs (34, 34a) cause the jaws to impose a mild pressure on the cables. Then fluid is introduced through the pipe (46), and into the chamber between the pistons (18, 18a) through the apertures (38, 38a). The pistons are biased towards their cable-receiving openings (6, 6a) so that the jaw-clusters bite into and are permanently set in the respective cables.

Title: Stop cock with low wear and friction seal - has shaft and cylindrical seal axes offset from each other to give jamming action on closing cock
IPC: F16K5/18
Filed: 1975-06-06
Abstract: The operating shaft (6) is mounted transversely between the inlet (4) and exit (5) ducts in the body (1) and is fitted with O-ring seals (10, 11, 12). It is increased in size in the flow passage region and carries the main seal (9). The seal is part cylindrical in form but its axis is offset from that of the shaft. Both of these axes are offset from the longitudinal axis of the flow passage. The net effect of these offsets is to allow the seal only to come into contact with the body when the tap is closed to allow an unobstructed flow path when the tap is open. An exterior quadrant and stop (8) prevent more than 90 deg. rotation.

Title: Alkylating highly disperse silicon dioxide - after steaming to desired degree of wetting
Inventor: CHUIKO ALEXEI ALEXEEVICH
IPC: C09C1/30
Filed: 1975-10-23
Abstract: Highly disperse SiO2-alkyl prods. (I) are prepd. by alkylating highly disperse SiO2 with alkyl chlorosilane vapours in a turbulent layer process. SiO2-alkyl prod. obtd. is then sepd. from the gaseous reaction prods. at 390-400 degrees C. The novelty is that the highly disperse SiO2 is steam treated at 110-120 degrees C before alkylation. Steaming is continued until degree of wetting of SiO2 is 2-40 mk mol. H2O/m2 SiO2. Subsequent alkylation takes place at 250-310 degrees C, e.g. for 5-15 min. (I) having alkyl gp. degree of grafting 8 mg mol./m2 SiO2 are used as fillers for silicone rubbers without use of stabilisers. Prods. having alkyl gp. degree of grafting 6.7 mk mol./m2 SiO2 can be used as thickeners for lubricating greases. With alkyl gp. degree of grafting of 4.7 mk. mol./m2 SiO2, prods. can be used as additives which prevent caking together of NH4NO3, and as fillers for lacquers and paints. The alkyl gp. degree of grafting on SiO2 surface can be controlled. Wetting forms a hydrate layer on SiO2 surface. On treatment with alkyl chlorosilane vapours, triple bond Si-CL are hydrolysed to triple bond Si-OH gps., which can then react with OH gps. of SiO2 surface under gentler conditions, e.g. 250 degrees C, 15 min., instead of 400 degrees C, 0.5 hrs.

Title: Transfer printing process for fabric web - endless band guiding web and band cleaning system (NL090676)
IPC: B41F16/02
Filed: 1975-11-28
Abstract: A fabric printing machine using a paper transfer strip has a cleaning unit (38 to 41) for a guide band (30) with heating elements (e.g. electrical resistance heaters, infra-red heating lamps, quartz lamps, microwave generators or gas flames) located within a chamber (31) to sublimate or evaporate ink from the endless band before the otherwise contaminated parts come into contact again with the fibric material. The temperature of the band must be heated to around 240 deg.C. Depending on the type of ink, the band material and the operational speed, a weaker or stronger heating is effected over longer or shorter times. Any steam or gases forming as a result of heating the band are removed through ventilation units (42) from the chamber.
Patent FR-2341081-A1 (FR)
Title: Anti-deflagration joint for use in explosive atmosphere - has recesses in joint faces giving turbulence in gas flow
IPC: H02K9/24
Filed: 1976-02-12
Abstract: The anti-deflagration joint is for use in explosive atmospheres and prevents flames from within a vessel escaping to the surrounding atmospheres. The two parts of the joint (2, 3) are separated by a small gap of about 0.1 mm wide. In addition recesses (10, 11) are formed in the joint faces which create a turbulence in the flow (f) of the flammable gas. The incorporation of the recesses (10, 11) into the joint permits the use of much larger tolerances in the dimensions (i) of the gap than is the case with joints not having these recesses. In addition the recesses trap any solid incandescent particles. The joint is particularly suitable for use with hydrogen.

Title: Implantable electrical terminal for organic tissue - is porous to intermesh with tissue without formation of fibrous tissue encapsulation
IPC: A61B5/042
Filed: 1977-01-26
Abstract: The terminal includes an electrically conductive portion having a surface for contacting the tissue electrolyte. This surface is surrounded with an inert non-absorbable porous material having interconnected and continuous pores with a dia. 10 - 500 mu. This permits the ingress of blood capillaries and intermeshing with the tissue without the formation of a fibrous tissue interface. Electrolytes in the tissue can thus come in contact with the electrically conductive portion of the terminal. For implanting in living human or animal tissue, as a component of e.g. a heart pace maker etc.. The living tissue does not build up a defensive fibrosis around the terminal which would insulate and isolate it from the vascularized tissue.

Title: Two=step deoxidation of steel - by pptn. of oxide(s) followed by slag metal exchange
Inventor: MOTTE JEAN-PIERRE
IPC: C22B9/10
Filed: 1977-04-14
Abstract: Method of deoxidising or metallic(steel) both after refining, for subsequent continuous casting, is claimed. Process comprises first precipitating oxides by addition of a deoxidant to the bath. Slag-metal exchange is then effected in the tundish of a continuous casting plant in the presence of a mixt. of products introduced in solid form, consisting of components of a metallurgical slag contg. in its oxidised form an energetic deoxidant. The activity of the oxide associated with the deoxidant used is as low as possible and in any case does not exceed during the course of treatment that which would be in equilibrium with a metallic bath, the O2 content of which corresponds to a killed state of the bath. By avoiding pptn. of Al2O3 and similar oxides in the tundish, the chance of blocking the exit orifice is made negligible, and loss of castability is avoided.
