Title: Hydroxy-indanyl-propylamine prepn. - using (2)-indanone-cyanhydrin with hydroxyl group protected by reaction with vinyl alkyl ether
IPC: A61K31/13
Filed: 1975-09-05
Abstract: 1-(2-Hydroxy-2-indanyl)propylamine is prepd. from 2-indanone cyanhydrin in which the hydroxyl group is protected by a vinyl alkyl ether group of formula RO.CH:CH2 (where R is 1-6C alkyl), by addition of an ethylmagnesium halide hydrolysing the reaction product and hydrogenating the imine to an amine group and removing the protective group. The product, an anorectic and lipolytic agent, is made in 55-60% yield without any increase in cost of raw materials. Typically, the cyanhydrin is protected by reaction with vinyl ethyl ether in THF, the solvent is evapd. and the residue in toluene is treated with ethylmagnesium bromide in THF, and the product hydrolysed. The imine in toluene is hydrolysed with LiAlH4 and converted into the hydrochloride (yield 57% of overall).

Title: Submerged probe signal reception system - comparison and validation process eliminating effects of high level noise
Inventor: CHERON J J
IPC: E21B47/12
Filed: 1975-09-16
Abstract: Comparison and validation is used during the transmission of a signal from a probe in a well shaft or pipe in a gas storage or transportation system. Effects of high level noise signals from electricity grid networks and railways are reduced, permitting accurate determination of water level. A low frequency signal from a submerged probe is received (40) and applied to a low pass filter (93) in a low pass amplifier circuit (92). A filter (97) is turnable to transmission frequency and its output is amplified (98) for rectification (99) and voltage to current conversion (100). A galvanometer (101) indicates signal level. A comparator (102) enables a reference level to be set and its output is indicated by a luminescent diode (106). A clock (110) output is integrated (107) for signalling (109). Illumination of both indicators signals presence of oscillations from the transmissions.

Patent FR-2359387-A1 (FR)
Title: Dryer for webs of fibre e.g. paper - cools felt loop between nips and presses out condensate
IPC: D21F3/02
Filed: 1976-07-23
Abstract: Wet webs of fibres such as pulp for paper are dried by passing them onto and round a cylinder. The web is supported by an endless felt which runs with it through a first nip formed by the drying cylinder and a first pressure roller. The felt is then diverted round a loop whilst the web continues on the drying cylinder to pass through a second nip formed by the drying cylinder and a second pressure roller. Between the first and the second nip the felt is chilled so as to condense the steam moving with it. The condensate resulting is then extracted from it by compression whilst it runs between the two nips. The felt may be chilled by projecting cold water on to it and sprays are positioned upstream to the pressure cylinders. One of these pressure cylinders following the cold water sprays is fitted with a suction box. Increases considerably the drying efficiency of the plant. The spraying and pressing has the added advantage of washing out esins and waxes which otherwise block the pores of the blanket.
