Title: Shuttleless loom reverse drive - meshed by sliding toothed wheel fitted with free-wheel clutch
IPC: D03C5/02
Filed: 1972-12-15
Abstract: Designed for a shuttleless jet loom, to reverse the operating components to extract a faulty weft, the motion is executed by operating a pneumatic piston against its return spring to push a rack across a crown wheel. The effect is to move the sliding toothed wheel on its shaft, disengage the free-wheel clutch, and impart a reverse drive as long as the piston is under pneumatic press. The purpose is to provide a simple and effective reverse drive motion, for as long as required, without using complex control units, electro-motors which could be over-loaded, or requiring time-consuming hand operations.

Title: Separation of diamonds from crushed diamond-bearing minerals - by adhesion to a rotating metal drum partially immersed in water
IPC: B07B13/00
Filed: 1973-09-19
Abstract: The difference in adhesive properties of diamonds c.f. their associated minerals is employed to separate diamonds from crushed ores. Diamonds adhere more rapidly than the associated minerals, and also produce a bond which is more stable in the presence of water. By applying both materials to adhesive under pressure and then immersing in water, the associated minerals fail to adhere while the diamonds have to be mechanically removed. In classified material of 5 to 10 mm size, 100% removal of diamonds is obtd. with a reduction in material to be sorted of 15-20 x 103 times. For unclassified material of 0-10 mm size 96-98% removal is obtd. with a 2000 times reduction. The device is compact and capable of high throughput and may run continuously for long periods, i.e. 8 hrs.

Title: Video signals recording equipment - has a laser beam for each signal which is modulated before projection onto film
IPC: H04N5/84
Filed: 1974-02-25
Abstract: The equipment records simultaneously and luminance, chrominance and sound signals. The recording is on photographic film for eventual transfer-reduction onto photographic disc. The equipment has, for each signal, a laser beam which penetrates into an acousto-optic modulator then into an acousto-optic deviator. The laser beam is deflected transversely to the film movement. For each video signal (luminance or chrominance) a first photoelectric cell receives a small part of the laser beam from a semireflecting device, a second cell which receives the residual beam of the modulator and a third cell which receives the residual beam of the deviator. The signals of the two latter cells are separately amplified to eventually control the acousto-optic modulator.

Title: Agitator for spherical, hemispherical or elliptical vessels - permitting mixing, solvent removal, drying and size reduction, in one vessel
Inventor: ARMANET PIERRE
IPC: B01F15/00
Filed: 1974-06-05
Abstract: An agitator for spherical, hemispherical or elliptical vessels has two or more arms, each with an edge following the contour of the vessel from the bottom to the part where the dia. is a max. and the other edge formed so that a section of the arm forms an angle with the vertical plane, which increases from the bottom to the top of the arm. Each arm has several, e.g. three, elements, the sections of which make angles with the vertical plane which increase from the bottom to the top, and angles with the horizontal plane which increase with respect to a reference radius. the upper end of each arm is approx. a tangent to the vessel surface and has a number of teeth near it. The agitator allows a series of operations to be performed in a single perfectly fluid-tight vessel, e.g. mixing, solvent removal, drying and particle size reduction, which normally necessitate three or four vessels in series. It creates a minimum of suction and can be used to prepare a mixt. of dry powders in any proportion with any degree of fineness and to incorporate a liq.

Title: Yarn cutting and clamping mechanism - has moving cutting blade coordinated with clamps to hold cut yarn end
IPC: D03D47/00
Filed: 1974-07-31
Abstract: The yarn clamping and cutting system, for use with a texturising process, incorporates a blade beld by at least one spring against a counter blade and pivoted to a slide. The moving blade works in conjunction with the stationary counter blade, the cutting edge of the moving blade being slanted, while the fixed counter blade is L-shaped. The clamping action is effected by a clamping spring acting on two opposing components, the yarn guide being moved to the side by a moving section of the clamp in the form of two sets. The moving section of the clamp is arranged with the slide and the moving blade to compensate for the tolerances experienced when working with yarns of varied dies. The moving blade and its spring are made of spring steel, and can be formed as a single integrated component. Similarly the clamping spring and the moving section can be formed as a single unit. The system ensures that the yarn is cut cleanly, and that the cut yarn end is secured and held to be extracted by hand.
