Title: Zig-zag stacking roller shutter - has hinge connections between slats blocked by matching-slat displacement vertically
IPC: E06B9/06
Filed: 1976-04-01
Abstract: The folding roller shutter, which needs no case for storage, comprises a number of parallel slats, interconnected on their sides and passing over a rotatable roller-shaped deflection unit, by which they can be raised and lowered. When the slats are raised on the front of the deflection unit, those on the back of it can be folded in sets of a fixed number each, stacking in a zig-zag pattern. On this rear side of the deflection unit (8), the formation of the sets of slats is effected by virtue of the fact that the hinge connections (3, 4) between the slats being assembled into sets (1, 1') can be blocked by displacing the corresponding slats (1') vertically (D). There may be a groove on the longitudinal side of every slat, for engagement by the other side of the next slat, when the slats are superimposed on the front side of the deflection unit.

Title: Circular platform lifting method - has sloping ring-shaped segmented platform pulled up around column by cables until horizontal
IPC: E04B1/34
Filed: 1976-08-04
Abstract: A platform to be raised to an upper position around a column from the ground level, is made up of a ring of segments ( ) of a circle, arranged around the column. The segments are in sets of three, hinged together, each set being pulled upwards by a lifting cable (4) attached to the middle segment of the set. The segments start at ground level resting on the ground, and leaving at and angle against the column (2) which has a tapered base portion (1). All the sets of segments are connected around their periphery by connecting members (6). The segments are then lifted while still at an angle up the tapered part, until they reach the parallel part (2) when, due to the suspension points (5) of the cables, their angle becomes horizontal. They are then secured.

Patent FR-2380557-A1 (FR)
Title: Radar pseudo-noise guidance system with spill over rejection - achieves suppression by decoding spill over at receiving antenna range from transmitter
Inventor: WAER RICHARD ROLLAND
IPC: G01S7/03
Filed: 1977-02-09
Abstract: The device is used for rejecting spill over from a pseudo-noise, continuous wave radar transmitting antenna. Spill-over is the energy transmitted directly from transmitter to receiver. It is undesirable and must be suppressed in order to be able to sense the desired reflected wave from a target. Suppression is accomplished by decoding the spill over at the receiver antenna range from the transmitting antenna. The desired signal is not decoded because the desired signal has a code corresponding to target range. The target signal, thus, remains broadband whereas the spill over is reduced simply to a single frequency larger than zero or equal to zero.

Title: Optical integrated circuit component using Langmuir film - as planar waveguide or photolacquer in mfg. microcircuits (NL 5.9.77)
IPC: G02B6/12
Filed: 1977-02-28
Abstract: Component for an optical integrated circuit, using a Langmuir film. The pref. component uses a substrate on which a waveguide incorporating a Langmuir film is deposited, esp. by plating or coating. The film is pref. a straight-chain fatty acid or its salt. The pref. application is a lithographic plate, using a substrate with a Langmuir film of material which can be polymerised by radiation. In the pref. mfg. process, a substrate is conveyed through a layer of the film material floating on a liq. subphase, thus obtaining the film on the substrate. For use with thin film optical elements which overcome some of the problems involved with conventional lenses, prisms, mirrors etc., by using planar waveguides. As the new Langmuir films have accurately aligned molecules, they can be used as photoresist or photolacquer in defining submicron patterns in microelectronic circuits; or in mfg. diffraction grids.

Title: Inhibition of crack propagation in gas pipelines - by surrounding with strengthening steel rope at intervals
IPC: F16L57/02
Filed: 1977-03-24
Abstract: The propagation of cracks in gaslines is inhibited by steel rope wound around pipeline at intervals along its length so that a surrounding portion of the line has the relationship Cveq/Cva >=3 (where Cva is the Charpy energy per unit area measured transversely of the unstrengthened line and Cveq is the equiv. Charpy energy per unit area of the strengthened portions of the gasline). Steel rope is pref. wound around the gasline without applying tension to the rope which has an ultimate tensile strength of 100-200 kg/mm2 and a Young's modulus of 18,000 - 21,000 kg/mm2. Damage to gasline by the propagation of a crack is reduced and the system may be applied during gasline installations or to gaslines already in use. Gaslines with pipes of poorer quality may be utilised.

Title: Ozone prodn. by passing air through pipe at zero potential - contg. coaxial metal wire at high potential, with surface projections maximising efficiency
Inventor: GIBERT JEAN
IPC: C01B13/11
Filed: 1977-10-14
Abstract: Appts. for making ozone comprises a pipe connected to earth at zero potential in which is placed a body connected to a source at high potential. Air is fed to one end of the pipe and leaves at the other. The body is a metal wire provided with projections and is coaxial with the pipe.

Investment costs are reduced and the yield in mg ozone per watt-hour is good. The installation gives good stability of operation, requires no maintenance and is applicable to the laboratory and industrial establishments, particl. for purificn. of effluents and water and industrial processes requiring ozone.
