Patent FR-2228011-A1 (FR)
Title: Support stand for glass sheets - has upright bars locked at bottom by tilting and pressing sheets against frame
IPC: B65G49/06
Filed: 1973-05-03
Abstract: The support frame has vertical members supporting struts at approximately 6 deg. from vertical. The glass sheets lean against these struts and are braced in place by bars locked at top and bottom. The top fixing is by means of a saddle over a rod, with a pin through both. The bottom fixing uses a lip inside the foot of the stand passing between two studs fixed to the bottom of the bar. The studs are positioned so that the bar can slide along the lip when in a vertical position. When tilted the studs are forced against the lip, elastically deforming one or other of the components, thus locking the bar rigidly in position.

Title: Liquid butane vaporising system - for the supply of gaseous butane from a liquid storage vessel
IPC: F17C7/04
Filed: 1973-06-14
Abstract: In the vaporisation of butane removed in the liquid state from the lower part of a storage vessel by means of a pump assembly, the liquid butane is heated to a pre-determined temp., its pressure being at least equal to the satd. vapour pressure at that temp., and the heated liquid butane under pressure is expanded into the gas space in the butane storage vessel, at least part of the butane vaporised by expansion being then retained in the vapour space of the vessel and delivered to gaseous butane consuming plants. In partic., the liquid butane pressure is raised by the pump assembly to 6-15 atmos., and the liquid is heated under pressure to 50-90 degrees C. Process permits adequate quantities of gaseous butane to be delivered to the supply main when the temp. of the liquid butane in the tank is too low to provide an adequate gas pressure in the vapour space.

Title: Thermo-printing textiles with sublimable dyes - using mineral oil or paraffin to improve dye penetration
IPC: D06P5/28
Filed: 1974-07-26
Abstract: In the thermo-printing of textiles by placing the material in face-to-face contact with a support carrying sublimable dyes then subliming the dyes so that they are transferred to the material, the textile is impregnated before the transfer with a mineral oil or paraffin, which is eliminated from the textile after the transfer. The oil or paraffin acts as a carrier for the dye which can thus penetrate throughout the whole of the fibre. Satisfactory dyeings are thus obtd. rapidly, without requiring slow or large calenders and without any problems due to different dye affinities of different types of fibre present. The process is applicable to tricots, non-wovens and carpets of natural and/or synthetic fibres.

Title: FM data transmission system - uses twin channel reception to obviate misinterpretation of sequential similar bits
Inventor: SINNASSAMY CHARLES
IPC: H04L27/10
Filed: 1974-12-31
Abstract: The 0 or 1 data signals (E) in this transmission system are frequency modulated (2) as F0 and F1 and transmitted. The receiver (6) causes F0 and F1 to be switched (7) alternately, at the bit rate (20), to two identical demodulators. Each demodulator has two band-pass filters for F0 and F1 (8, 9), envelope detectors (12, 13) and an amplitude detector (16). The output of each demodulator is connected to a sampling switch (19). This gates a sample at the end of each bit period to achieve a pulse output. With this switching of demodulators, each bit is detected without error when the frequency does not change between identical and sequential bits. This enables narrow band filters to be used for an improved signal to noise ratio.

Title: Metallic seal allowing movement of sealed faces - incorporates corrugations in metal sheets formed as mirror images
IPC: F16J15/08
Filed: 1976-05-21
Abstract: Metallic seals made by corrugating thin sheets of metal are often used to seal between flanges when a degree of movement may exist between the flanges. In current designs, this generally results in one side of the seal having fewer contact lines than the other and this implies that for equivalent sealing on each side, a higher contact force is necessary than would be the case with equal numbers of contact lines. In this design, the shape of the upper surface of the seal is made a mirror image of that of the lower. The symmetry then reduces the sealing loads necessary. In practice, shaped edges (24) may be made separately from and surround a flat central portion (23, 29) of the seal, or a re-entrant folding technique (18) may be used on the edge of the seal (17b, 17c). Both methods are also appliable to multiple laminar seals.

Title: Ornamental funerary plate - with polyester resin base, plastic or ceramic flowers and colourless resin coating
IPC: B44C5/00
Filed: 1976-07-06
Abstract: Device for mfg. ornamental funerary plates operates by depositing plastic or ceramic flowers or any other decorative object on a base of loaded coloured polyester resin, and pouring on top several mm. of colourless resin. The latter renders the flower or object integral with the base, due to simultaneous polymerisation of the base and of the upper layer. Pref. a text or design is incorporated, which will be covered by the liquid resin during casting of the upper layer. The plate may be coated with a layer of anti-static anti dust varnish. The flowers have a high resistance to detachment. As the resin used has a gelling time of 15 mins. to 1 hr., the two layers become polymerised to form a homogeneous mass, preventing sepn. of the flowers.
Patent FR-2332859-A1 (FR)
IPC: C08L61/20
Filed: 1976-11-16
Abstract: Wood-based materials with reduced formaldehyde elimination are produced by pressing wood components which have been provided with curable formaldehyde resins as glue. For binding free or liberated formaldehyde, cellulose fibres which have been treated with formaldehyde-binding agents are added to the wood components during or after the gluing. By this process, on the one hand the moisture uptake of the chipboards is delayed and on the other hand the formaldehyde-binding agents are only free when the moisture content of the chip wood increases.

Title: Transformer based static converter - uses logic techniques and transformer harmonic suppression characteristics to minimise LC filter weight (SW 4.7.77)
Inventor: SHERLOCK JAMES
IPC: H02M7/49
Filed: 1976-12-10
Abstract: The static converter or oscillator works from a DC power source providing 'N' output phases without the use of large LC filters normally associated with providing a sinusoidal output from a basic square wave source waveform. The design is based on the harmonic suppression characteristics inherent in static phase transformers producing an envelope of low range harmonics. The phase transformer has preferably the same number of paths and windings as the number of output phases. The phases are controlled using a fourteen step logic signal corresponding to a signal of three pulses per half cycle combined with a half amplitude square wave.

Title: Water tap valve with reduced seal wear - has dual sliding pistons with O-ring seals mounted in perforated sleeve in body
IPC: F16K3/26
Filed: 1977-02-14
Abstract: The water tap valve has a body with inlet and discharge ports, an inner sleeve with upper and lower external O-ring seals and having holes near the upper seal and two internal pistons. The upper piston slides up and down the bore of the sleeve under the action of the tap screw, blocking off the holes in the sleeve in its upper position and allowing free passage of water in its lower position. This piston also pushes the lower piston as it moves down and this moves an O-ring seal on the outside of the latter away from its seat in the enlarged bore at the lower end of the sleeve. Water can then pass through the lower piston, which is hollow, to the discharge port.
