Patent FI-973633-A (FI)
Inventor: VIRTANEN PENTTI
IPC: C01F11/18
Filed: 1997-09-08
Abstract: The invention is related to a method for forming calcium carbonate. In the method, calcium oxide is reacted with carbonate ions in the presence of water to produce calcium carbonate. According to the invention, the formation is carried out directly from calcium oxide to calcium carbonate without intermediate stages in a three-phase precipitation, whereby the hydration of the calcium oxide to calcium hydroxide and the carbonation of the hydrated part are carried out immediately after one another under so intensive agitation that the calcium carbonate elements thus created are detached from the surface of the calcium hydroxide. The mixing is preferably carried out in a fluid medium where the amount of gaseous phase is at least 20 parts by volume and the amount of liquid phase is 0.5 to 1 part per one part by volume of the solid matter of the suspension. In the process, the desired end product, PCC, can be prepared in a very short residence time and with a small operational content.

Title: A process for protecting synthetic fibres from ultra-violet rays
IPC: D06M13/35
Filed: 1960-01-12
Abstract: Fully synthetic fibres, e.g. polyamide, polyvinyl chloride, polyethylene, polypropylene, polystyrene, polyacrylonitrile and polyester fibres, are protected from ultra-violet rays by fixing on them fron an aqueous bath a colourless or at most slightly coloured compound of the formula:-  <FORM:0879144/IV(c)/1> in which R1 and R2 represent aromatic residues of the benzene series and two vicinal carbon atoms of the residue R2 form members of the triazole ring and the residue R1 contains a free hydroxyl group, an etherified hydroxyl group or an acyloxy group in the ortho-position relatively to the bond with the triazole ring.  The residues R1 and/or R2 may be further substituted by halogen atoms, branched or unbranched alkyl groups, trifluoromethyl, hydroxyalkyl or aralkyl groups, phenyl groups which themselves may be substituted, carboxylic acid, carboxylic acid ester, sulphonic acid, sulphonamide, alkysulphonyl, arylsulphonyl or aralkylsulphonyl groups, primary, secondary or tertiary amino groups, free hydroxyl groups or alkoxy or acyloxy groups.  The triazole compound may be dissolved or dispersed in the aqueous bath, which may be acid to weakly alkaline, if necessary with the aid of an anionic or non-ionic dispersing agent, e.g. an addition product of ethylene oxide with a higher alcohol, or the triazole may be dissolved in an organic solvent which is miscible or soluble in water, e.g. methanol, ethanol or acetone, and the solution then poured into water, or dispersion may be effected, by the use of a colloid mill.  The fibres, which may be in the form of loose fibres, hanks or woven or knitted fabrics, may be treated at 80 DEG -120 DEG C. for 20-120 minutes to fix 0,1-5% by weight of the triazole compound, based on the weight of the fibres.  The treatment may be combined with treatment to impart an antistatic finish or soft handle or with dyeing.

Abstract: 739,917. Variable-speed gearing. FIAT SOC. PER AZIONI. Jan. 14, 1954, No. 1139/54. Class 80 (2). Variable-speed epicyclic friction gearing comprises three rows of interengaging balls 2, 3, 4 coacting with annular races on driving, driven and reaction members, the axial position of one of the latter relative to the other two being adjustable to vary the speed ratio. The balls 2 engage races on members 1, 6, the balls 4 engage races on a member 5 and a ring 7 freely rotatable in member 6, and the intermediate balls 3 engage a freely-mounted guide ring 9, contact being maintained by a spring 10 between members 1, 5 or by fluid-pressure or electromagnetic means. In Fig. 1, shaft 1 drives, shaft 5 is driven, and member 6 is non- rotatable. The member 6 or the assembly 1-5 is moved axially to vary the speed ratio. In Fig. 4, member 6 is rigid with the driving shaft 19, and member 5 is held against rotation in one direction by a.one-way detent 24, or alternatively is held against rotation in both directions, so that member 1 is driven forwardly or reversely as the assembly 1-5 is moved in one or other direction from central position. This gear is combined with a spur epicyclic gear cf which the sun 20 is rigid with shaft 19, annulus 12 -is rigid with member 1, and carrier 23 is rigid with the output shaft 21. The assembly 1-5 is movable axially from central position by supplying pressure fluid to one or other side of a plunger 15 on shaft 19 in a cylinder 16 in member 1 under the control of a valve operated manually or automatically under torque control, or by mechanical or electromagnetic means. The members 1, 5 may be locked together by a clutch ring 25, the member 5 being at the same time freed from restraint by the detent 24, to obtain direct drive.

Preferably, the rollers are lowered only when a certain minimum speed has been attained, such operation, if desired, being automatic. In the construction shown, the stepped hydroplane bottom of the craft 1, which is propelled by airscrews, is provided with a number of recesses each accommodating a roller 2 mounted on the free end of a pivoted forked frame 3, the recesses being closable by slides 13 to preserve the general contour of the bottom of the craft when the rollers are raised. For raising and lowering the rollers, each forked frame 3 is embraced by a yoke 10 which is pivotally connected at its upper end to a screw 8 rotatable in a fixed nut 9 and having internally splined thereto a bevel wheel 7, which is driven by one of a series of bevel wheels 6 rotated by a common control shaft 5. The rollers are themselves rotated about their horizontal transverse axes through shafting and carden joints either from a common shaft or by individual motors. The rollers may be automatically projected when a certain speed is attained by operating the shaft 5 by a motor controlled by a switch which is in turn operated by a speedometer. In their projected position, the rollers may also function for beaching purposes.
