Patent WO-0104041-A2 (WO)
Title: Offshore loading system by suspended piping
Inventor: LE DEVEHAT RENAUD
IPC: B63B27/24
Filed: 2000-07-07
Abstract: The invention concerns an assembly for transferring fluid (13) between a first site and a second site, comprising: a winch (40) for the first site (10) whereon is wound a suspension cable (17) designed to be stretched between the two sites (10, 11) and which is adapted to subject the cable to constant tension; a support (14) for the first site and for storing in suspension rigid pipe sections (15) mutually articulated via articulating sections (16) with rotary bends and joints, so as to shift from a storage position wherein the pipe sections (15) are suspended accordion-like to the support (14) to a stretched position between the two sites (10, 11) by being suspended to the cable; and means for coupling (22) some of the articulating sections (16) to the support (14) or to the cable (17) depending on the length of the cable stretched between the two sites (10, 11).
Patent FR-2180543-A2 (FR)
Title: Liquid crystal cell - for directing light by varying pd across electrodes
IPC: G02F1/31
Filed: 1972-04-20
Abstract: Light beam directing device comprises a cell filled with liquid crystal (nematic or cholesteric type) of variable refractive index depending on the p.d. across electrodes fixed on opposite walls, both walls being transparent. The rear wall has a mirror coating behind it in contrast to parent patent device where the mirror is in front. The oblique angle of incidence of the beam is such that it can be completely reflected or refracted through the cell with a change of potential. The divergence of the beam is increased by increasing the effective path of the refracted beam.

Title: Twin-wire papermaking appts. - with stock inlet passageway having straight and parallel walls
IPC: D21F9/00
Filed: 1973-11-29
Abstract: The inlet to the papermaking machine consists of a relatively long passageway formed from approx. parallel impervious walls. The stock flow is accelerated in this passageway until equilibrium conditions are established and the entire flow of the suspension is moving uniformly in the same direction at the same speed. A pair of forming carrier wires enter the inlet section, and run along the terminal sections of the walls of the passageway. They capture the flowing stock, without any web formation, and transport it to the forming section where water is removed from the suspension to form a paper web. By controlling the uniformity of the stock flow a better quality paper is produced.
Patent FR-2274036-A2 (FR)
Title: Automatic analysis of filterability of combustible liquid - utilises simple binary counter in temperature measuring process
IPC: G01N11/02
Filed: 1974-06-06
Abstract: Continuous analysis of the filterability of a combustible liquid includes continuously measuring the temperature of a mass of the liquid during enforced cooling. By suppressing the numerical display of temperature a simple digital counter is used in place of a double counter system. The output of a digital counter feeds into a digital to analogue converter to cause a stepped output voltage which is then compared with the voltage representing the temperature of the tested combustible liquid. Each step from the converter represents one degree centigrade and the comparator causes the counter to progress one step when the last temperature is less than one degree from the reference temperature. The time base and the sample liquid are then released.

Title: Sprung temporary plug clamp for rivetting - locates parts prior to rivetting process esp. in aircraft construction
Inventor: MOTTAIS JEAN LOUIS OLIVIER
IPC: F16B2/02
Filed: 1974-08-02
Abstract: The clamp comprises a generally cylindrical body with an aperture at one end through which extend two elongate clamp members arranged one on either side of the tongue of a 'T' shaped spreading member. The elongate clamp members pass along the inside of the cylinder and are connected to a push knob at its other end. The knob is urged outwardly by a compression coil spring which runs inside the cylinder and which also bears on the base of the "T" shaped spreading member. Depression of the knob allows the two clamp members to be engaged in a hole in the workpiece and releasing the knob causes the spreader to spread the clamp members apart so that they are firmly retained in the workpiece. Several alternative embodiments are possible.
Patent FR-2328058-A2 (FR)
Title: Continuous pptn. conditions for mfg. polyolefin fibres - using constricted tubes and heavy solvents to avoid agglomeration
IPC: D01F6/04
Filed: 1975-10-15
Abstract: The parent patent described the prepn. of polyolefin fibres by passing a dilute soln. of the polymer through tubes. In one zone of the tube(s) the flow rate was above a critical value and the temp. was in a critical range such that polymeric fibres were pptd. from the soln. and remained out of soln. thereafter. The solvents quoted were hexane, cyclohexane, mixed xylenes or other solvents liq. under ambient conditions. This addn. extends the scope of suitable solvents to matls. which may be solid at ambient temps. but which melt at temps. below the solubility temp. of the prod. fibres. The solvents are paraffins or waxes, pref. fractions obtd. from raffinated petroleum. The pptn. zone of the tubes is modified to incorporate >=1 restriction. The alternative solvents are cheaper, and/or less volatile and/or less toxic and/or less highly flammable than those quoted formerly. The process does not necessarily require presure resistant vessels, and operating procedures/safety precautions can be simpler. The flow characteristics of the suspended fibres and the more viscous solvents are better matched, resulting in less agglomeration of pptd. fibres. Papers made using such fibre from such suspensions are more homogeneous, feature fewer 'nodules'. Esp. used for producing polyolefin fibres typically 0.1-20 mm. long, 5-200 mym dia., for making or coating papers. Conversion efficiencies are in the range 50-90%.

NaOH at 100 degrees C, extracting with ether and acidifying the extract with HCl.

Title: Position detector without mechanical contact - partic. useful for detecting position of rods in a nuclear reactor
IPC: G01D5/20
Filed: 1976-09-09
Abstract: A primary winding is fed with a source of alternating current. The secondary winding is coupled inductively with the primary winding and subdivided into elementary coils, stepped along the path, and connected electrically in apirs. The movable element has a magnetic part which changes the inductive coupling. The improvement consists of subdividing the primary winding into an equal number of elementary coils as the secondary winding and associating each secondary coil with a primary coil, the two coils being wound one on the other. Each pair of coils is surrounded by a magnetic screen. Flux leakage is reduced and precision is increased. The close coupling gives concn. of the magnetic field and a signal which facilitates electronic treatment.
