Patent FR-2581211-A1 (FR)
Title: Slide-projection device having a xenon light source fitted with a convergent lens
Inventor: RUELLAN YVES LOUIS JEAN
IPC: G03B21/20
Filed: 1985-04-25
Abstract: The device uses a conventional slide-projection device 1, deprived of its own light source. A xenon lamp 2 fitted with an elliptical reflector 13 produces a beam of convergent light, reflected by a cold-light mirror 4 to a focal point F. An aspherical convergent pyrex lens 15 is provided shortly after the latter. This lens 15 makes it possible to obtain a substantially even illumination over the slide, even with the insertion of a movable mask 18 in a plane P located slightly downstream of the lens.

Title: Point marker for games of bowls
IPC: A63D5/04
Filed: 1985-06-17
Abstract: The invention relates to a device permitting progressive recording of the points obtained by each of the two teams in a game of bowls, displayed on the same board, numbered from 0 to 15, with the aid of two indicator needles 15 and 16. These needles are independent of each other and in different colours and are mounted on a fastening system which eliminates movement of one by the other during manual manipulation. This system consists principally of a threaded shaft 17 with a thrust washer 18, ring 19, four washers 20, and nuts 21 and 22 which ensure tightening of the assembly, immobilisation of the system being guaranteed by virtue of the square nut 23 and the square-hole washer 24 which is screwed onto the panel 9 via three screws 25. The board comprises, at the top, two areas made from plastic for dry erasing or a slate for marking with a felt-tip pen or with chalk, as appropriate, the names of the two teams. The fitting-out of bowls clubs and holiday villages may be mentioned among the most interesting applications of the invention.

Title: Twin lumen bronchial tube assembly
IPC: A61M16/04
Filed: 1985-12-12
Abstract: The twin lumen bronchial tube assembly with a bronchial tube (1) and a tracheal tube (10) has an inflatable cuff (2) that encircles the patient end (12) of the bronchial tube in the region of the right upper lobe (32). The bronchial cuff, when inflated, is of pear shape and circular section, having a channel shape recess (24) extending from the patient end of the cuff rearwardly by about two thirds of its length. The recess is formed by adhering a longitudinal strip of the cuff to the outer surface of the tube.

Title: Humic and inorganic fertilising product having an immediate and long-lasting effect
IPC: C05F11/00
Filed: 1986-06-10
Abstract: The fertilising product, being composed of 50 % ligneous components, 25 % plant components, 3 % components of animal origin, 11.5 % inorganic components and 1.5 % polyuronides, is well equilibrated and provides the plant with the nutrient elements necessary for all stages of its development, without risk of scorching. Part of the inorganic fertilisers, 2 %, are intimately incorporated into the peat, 3 % of the fertilisers in the form of granules are coated once, 3 % of the fertilisers in the form of granules are coated twice. The porous stones, laden with inorganic components, 2.5 %, and also coated with urea-formaldehyde, are extremely important for the general equilibrium of the fertilisation, since the nutrient irons are only released depending upon the requirements of the plant. The colloidal products incorporated into the earth with this fertilising product, the porous stone and the ligneous products retain water and inorganic components close to the roots. The polyuronides in this mixture stimulate the bacterial activity without which no harmonious vegetation is possible.

Patent FR-2608459-A1 (FR)
Inventor: ARIES LUCIEN
IPC: B01J37/34
Filed: 1986-12-17
Abstract: Method for fabricating microporous catalysts obtained from the treatment of the surface of a metal substrate. The method comprises the immersion into an aqueous bath containing a dissolved chalcogen particularly sulphur, a ferrous alloy containing chromium in order to form a layer which forms a microporous medium of fine particles corresponding to a mixture of oxides, chalcogenides and metals concerning the elements of the first line and column VIII of the classification (Fe-Co-Ni) and the elements of column VI (Cr, Mo, W). The corresponding powder may be obtained by detaching the layer from its support. The utilization of the material as catalyst for hydrogenating carbonaceous substances leads, in the case of coal hydroliquefaction, to a considerable increase of the conversion rate (from 68 % to more than 95 %) and of the liquefaction rate (45 % to more than 80 % in the case of the Freyming coal) with respect to tests without catalyst.
