Title: Production of an improved finish in textile products
IPC: D06M101/16
Filed: 1973-04-10
Abstract: 1424698 Coated fibres/fabrics INTERCOOPERATION KERESKEDELEMFEJLESTTESI RT 10 April 1973 [20 April 1972] 17076/ 73 Heading B2E [Also in Division Dl] A layered finish on the fibres of cellulosic textile fabrics is produced by saturating the fabric or fibres from which it is to be made with a water soluble cross-linkable synthetic resin monomer and/or oligomer and a crosslinking catalyst so that some of the monomer and/or oligomer and catalyst diffuse into the fibres, washing the monomer and/or oligomer and catalyst from the surface of the fibres by means of an aqueous sol of a colloidal surface active substance which forms a resilient film on the fibres without diffusing into them, and fixing the monomer and/or oligomer diffused into the fibres by crosslinking and drying. Preferred monomers and/ or oligomers are dimethylol-methylene carbamide, dimethylol-dihydroxy-ethylene carbamide, trimethylol-melamine, hydroxy-ethyl-thiazone, hexamethylol-melamine, dimethylol-carbamide. The cross-linking catalyst may be selected from: MgCl 2 , ZnCl 2 , (NH 4 ) 2 SO 4 , Al 2 (SO 4 ) 3 , Zn(NO 3 ) 2  and ammonium tartrate. The colloidal material is preferably a protein derivative cross-linked to colloidal size with aldehydes, carboxy-methyl-cellulose, cellulose ethers or starch ethers, partially acetylated polyvinyl alcohol, methylol melamine-based acid colloid, or aqueous polyurethane dispersion. Preferably a further layer is applied to the uppermost layer of the colloidal material by treating the latter, before fixing, with an aqueous solution of compounds suitable for making a covalent bond with the colloidal material, e.g. N-stearyl-acrylamide, stearylmethyl-pyridine-ether, N-stearyl-methylamide, methylene-pyridine-chloride. The colloidal material may be used as a solution which also contains cross-linkable monomer and/or oligomer and a catalyst in concentration 50- 200% of the concentrations used in the first impregnating solution. The impregnation with the monomer and/or oligomer and the catalyst and the application of the colloidal material is preferably performed with a padder. The material to be treated may be cotton or bast fibre fabric, hemp, china glass or mixtures thereof with regenerated cellulose, a fabric of cotton mixed with polyester, regenerated cellulose-based or linen fabric. In a typical example cotton fabric was impregnated with a solution of dimethylol-ethylene-carbamide and magnesium chloride by a padder and without intermediate drying the treated cotton fabric was padded with a gelatin solution pre-treated with formaldehyde. After the padding treatment the cotton fabric is dried on a tentering frame and condensed.

Examples 5 and 12 describe the production of hard films from cyclopentadienyl titanium dibutoxy trichloracetate and biscyclopentadienyl titanium dioleate respectively.  Example 4 describes the production of polymethyl methacrylate using biscyclopentadienyl titanium di(trichloracetate) as catalyst, and Example 14 describes the production of polystyrene using as catalyst biscyclopentadienyl titanium diglycollate.ALSO:The invention comprises compounds of formula:  RxTiXy(OOCR1)z where R represents a cyclopentadienyl or substituted cyclopentadienyl radical bound to titanium by a Ti-C bond, the carbon atom of said bond being a member of said radical, X is a halogen atom or an alkoxy group, R1 is an alkyl, haloalkyl, mercaptoalkyl or hydroxyalkyl radical, x is 1 or 2, y is 0, 1 or 2, z is 1 or 2 and (x+y+z)=4. The cyclopentadienyl radical may be alkyl-substituted or may contain fused rings as in indenyl and fluorenyl.  R1 may contain 1 to 18 carbon atoms, corresponding to acetic, propionic, butyric, lauric, myristic, oleic and stearic acids, as well as being derived from acids such as chloracetic, dichloracetic, trichloracetic, thioglycollic, mercaptopropionic and glycollic acids.  They may be prepared by reacting compounds of formula Rn TiXm where R and X are as above, n is 1 or 2 and m is 2 or 3, at least one X being halogen, and an alkali metal salt or alkaline earth metal (including magnesium) salt of the acid corresponding to the acylate group desired.  The reaction may be carried out in a solvent such as tetrahydrofuran, dimethylformamide, acetone and dimethylsulphoxide, and in the absence of air and moisture.  When the compound Rn TiXm is a mixed halide-alkoxide, the halide atom only is replaced by the acylate group giving an alkoxide acylate.  The compounds of the invention may be used as polymerisation catalysts and may be hydrolysed to give titanones having Ti-O-Ti-O chains (see Group IV(a)).  In the examples there are prepared (1) biscyclopentadienyl titanium diacetate, (2) di (monochloracetate, (3) di (dichloracetate), (4) di(trichloracetate) (5) cyclopentadienyl titanium dibutoxy trichloracetate, (6) biscyclopentadienyl titanium monochloracetate chloride, (7) di-indenyltitanium di (trichloracetate), (8) biscyclopentadienyl titanium dithioglycollate, (11) biscyclopentadienyl titanium distearate, (12) di-oleate, and (14) diglycollate.

Title: Improvements in transmitters or master cylinders for hydraulic transmission systems
IPC: F15B3/00
Filed: 1938-06-09
Abstract: 515,709. Hydraulic transmission of power. LEPERSONNE, O. June 9, 1938, No. 17218. Addition to 431,202. [Class 69 (ii)] [Also in Group XXXIV] In the master cylinder of an hydraulic transmission system suitable for brakes, as described in the parent Specification, the valve 17 which puts the low-pressure cylinder 6 into communication with the liquid reservoir 13 is extended in the direction of the high-pressure cylinder 24 by a rod 22 on which slides the valve 19 placing the two cylinders 6, 24 in communiction, said rod 22 extending into a compartment 15 connected with the receivers. The rod 22 carries a stop 21 for the valve 19, so that the valves 17, 19 serve as stops one for the other, and these two valves are prevented from opening together by making the face of the valve 17 exposed to the pressure in the bore 14 at least equal in area to the face of the valve 19 exposed to this pressure. A constriction 16 between the bore 14 and the seat of the valve 17 prevents this valve opening, upon a sudden increase in pressure in the bore 14, before a sufficient quantity of liquid has been forced through the valve 19. The ratio between the sections of the low and high pressure pistons 2, 3 is smaller than that between the section of valve 19 and the rod 22. so that. when the low-pressure cylinder 6 is cut off, by closing valve 19 and opening valve 17, the change over from low-pressure action to high-pressure action takes place progressively. In a modification, the valves 17, 19 are disposed within the pistons and the valve 5. which serves for refeeding the cylinder 6 during the return stroke of the piston, is situated laterally of the cylinder 1.
