Title: Differential refractometer for liquid chromatography - uses image displacement technique with periodic gratings as analyser
Inventor: SIMON JACQUES
IPC: G01N30/74
Filed: 1975-01-22
Abstract: The method measures the refractive index of liquid chemicals using the differential image displacement technique. A periodic grating is illuminated by a source of light (1), the image being formed on an analyser comprising two identical periodic gratings (6) which are shifted w.r.t. each other by half a wavelength. The periods of the grating and the analyser are optically conjugated. Following passage through a double liquid (4) prism which produces by refraction the displacement of the image of the grating on the analyser, the light signals from the two analyser, the light signals from the two analyser gratings (6) are received separately (71, 72) and the difference signal (30) is proportional to the refractive index difference between the two prisms.

Title: Mfg. corrugated building sheets - by rolling plane sheets between gear wheel type rollers
IPC: B21D13/04
Filed: 1975-02-14
Abstract: The process for the fabrication and assembly of corrugated sheets or cross-corrugated sheets involves passing plane sheets between gear wheel type rollers with symmetrical trapezoidal section teeth. Pref. two alternative types of primary rollings are utilized, one in which opposed roller teeth do not inter-penetrate fully but produce sinusoidally corrugated sheets, and one other in which full teeth interpenetration produces trapezoidal corrugations. In section the latter are semi- hexagonal and a post-roll rectifying press is used in the process. Roller wheels can be conical, obtg. a fan shaped taper-corrugated product, and the products include; curving retractable doors moved by rubber cog wheels; concrete sandwich panels; and members formed by two opposed single-pitch corrugations.

Title: Engine cooling fan drive clutch - has wax capsule immersed in oil and expanding to overcome spring allowing clutch engagement
IPC: F16D43/25
Filed: 1975-09-11
Abstract: The cooling fan for an air cooled engine is driven through a clutch assembly with a needle roller bearing between the driving member and driven member. Springs fingers exert a force which tends to force the clutch plates against a friction disc. This force is normally opposed by a spring acting through rods and a disc. A temperature sensitive wax capsule is fitted in a bore of the crankshaft and is immersed in the engine lubricating oil. when the oil temp. exceeds a pre-determined value, the capsule expands and overcomes the force of the spring thus allowing the spring fingers to engage the clutch and drive the fan.

Title: Microwave heat treatment of articles, e.g. of refractory material - with avoidance of plasma formation near article being treated, increasing speed of treatment and possibly higher temps.
Inventor: JAMOIS GUY
IPC: H05B6/78
Filed: 1977-01-24
Abstract: Process for thermal treatment of an article by microwaves includes avoiding the formation of plasma in the neighbourhood of the article. The formation of plasma may be avoided by e.g. limiting the power emitted by the micro-wave source; by using a current of neutral gas, e.g. air, N2, Ar, He; by creating near the article an electro-magnetic blow-out of the plasma; or by maintaining a partial vacuum. The treatment can be more rapid and higher temps. can be reached than in existing processes. Typically, with an installation for treating refractory materials, according to existing technique the power delivered is =700 W. By avoiding the formation of plasma it is possible to deliver 1.5kW.
