Title: Spermidine homologues prepn.
Inventor: LEBRETON LUC
IPC: C07C271/20
Filed: 1994-08-16
Abstract: Spermidine homologues of formula (I) (n=3-5; R=1-4C alkyl), are prepared by reacting dibenzylamine with an alkyl vinyl ketone of formula CH2=CHCOR (II) in a solvent (methanol) at 0-60 deg C for 5-24 hours, to form (C6H5CH2)2N(CH2)2COR (III). The keto group is reduced (NaBH4) in a solvent (ethanol) at 15-25 deg C for 2-12 hrs to form (C6H5CH2)2N(CH2)2CHOHR (IV) and this is catalytically reduced (H2/Pd on C; methanol; 10-40 deg C; atmos. pressure) to give C6H5CH2NH(CH2)2CHOHR (V). This is then reacted with an w-cyanoalkyl halide of formula Hal(CH2)n-1CN (Hal = Cl or Br) in refluxing butanol in the presence of an alkaline carbonate and opt. in the presence of an iodide for 2-24 hrs to give (VI). The alcohol function is esterified using methane sulphonyl chloride in diethylether or a halogen solvent, in the presence of an aprotic base e.g. triethylamine or pyridine at -20 - 35 deg C for 1-24 hrs, to give (VII). Reaction with sodium azide in DMSO at 20-60 deg C for 4-20 hours gives (VIII). This is then reacted with hydrogen in the presence of di tert. butyl dicarbonate and a catalyst (Pd/C), under a H2 pressure of 1.5-5.1x10<5> Pa, in a solvent e.g. ethyl acetate, at ambient temp. for 5-20 hrs, to give (IX). Hydrogenation of (IX) in the presence of Raney nickel in ethanol saturated with ammonia gas at a pressure of 2-40x10<5> Pa for 6-24 hours gives (I).

Title: Procedure for transmitting concealed message to recipient
IPC: B42D15/02
Filed: 1994-08-24
Abstract: The procedure uses a main printed surface (1) with a concealed message (11) on one of its faces, and a second printed surface (2) which reveals the concealed message to the sender. The message, covered by a thin layer of a removable material, is then transmitted, e.g. in the form of a postcard, to the recipient (B), who scratches off the layer to read the message. The concealed information can form part of a complex message, of which the other part is immediately legible, e.g. a question and an answer. The printed surface carrying the concealed message could be supplied in a package or envelope which reveals the concealed message to the sender.

Patent FR-2724220-A1 (FR)
Inventor: BARBAUD JEAN
IPC: F28C1/12
Filed: 1994-09-07
Abstract: Wet cooling tower comprising an exchange body (20), a water dispensing network above the exchange body provided with valves (16) supplying each of the water nozzles located above a section of the exchange body to form cooling cells which can be isolated, and a manifold for water which has flowed through the water exchange and pumping body directing the water collected towards the dispensing network. The cooling tower comprises static means for automatic limitation. The increase in the hydrostatic pressure applied to the nozzles beyond a given value, above the value attained when all the cells are operational, is automatically static limited. Part of the water flow which is brought to the distribution level, is therefore bypassed upon exceeding a given value.

Title: Stabilisation of in-flight aircraft refuelling holder
IPC: B64D39/00
Filed: 1995-07-11
Abstract: The holder is composed of three assemblies. The first (1) constitutes a central hub which is mounted at the end of a flexible supply pipe. The second (2) constitutes the funnel which is formed from a number of pivoted ribs (17) The third (3) constitutes an annular fin which rotates on a ball joint (5) forming part of the central hub. The first assembly has a central body (4) with a fuel valve system. Neutralisation and stabilising of the variation in aerodynamic forces on the holder body is obtained by the annular fin. This rotates in the manner of a weather vane around the ball joint fixed on the holder central hub. A variation in the incidence of the flow around the holder produces a return couple on the fin which neutralises this variation.
