Filed: 1943-07-23
Abstract: Addition agents for crank-case lubricants of Diesel engines (see Group III) comprise oil-soluble metal-containing aromatic compounds containing an ester group and a metal mercaptide radicle MS-directly attached to the aromatic nucleus, but excluding compounds having an aliphatic hydrocarbon group having 20 or more carbon atoms linked to the aromatic nucleus.  These compounds may be prepared by first preparing an ester <FORM:0665091/IV (b)/1> where X is oxygen or sulphur and R and R1 are organic radicles at least one of which is aromatic and contains an SH group, and then replacing the hydrogen of the SH group with a metal.  Various substituent groups including hydrocarbon radicles, halogens, oxygen - bearing radicles, nitrogen-bearing radicles including amides, and sulphur-bearing radicles including sulphonates which may be present are specified. Metal mercaptides specified include those of calcium, magnesium, barium, zinc and aluminium.  Magnesium mercaptide of paramer-capto-phenyl thiololeate is prepared by stirring dithiohydroquinone with benzene, pyridine, and oleyl chloride, removing the precipitated pyridine hydrochloride, drying, and evaporating the benzene to give para-mercapto-phenyl oleate, which is treated with magnesium methoxide to give the magnesium compound. Calcium mercaptide of para-mercapto-benzyl oleate is prepared by refluxing sodium oleate with para-nitrobenzyl-bromide in toluene to give para-nitrobenzyl oleate, reducing by catalytic hydrogenation to the corresponding amino compound, diazotizing, and treating with potassium xanthogenate to give paramercapto-benzyl oleate which is then treated with calcium methoxide to give the calcium compound. Specification 665,107 is referred to.ALSO:A crankcase lubricant particularly for Diesel engines comprises a major proportion of mineral lubricating oil and a minor proportion of an oil-soluble metal-containing aromatic compound containing an ester group and a metal mercaptide radicle MS-directly attached to the aromatic nucleus, but excluding compounds having an aliphatic hydrocarbon group having 20 or more carbon atoms linked to the aromatic nucleus.

Title: Plasticized papers
IPC: B65D65/40
Filed: 1975-03-24
Abstract: 1500542 Paper prepared from plastics fibrils; papermaking machines MONTEDISON SpA 24 March 1975 [25 March 1974] 12088/75 Headings D2A and D2B A process for making paper from thermoplastic fibrils comprises forming a wet sheet of superimposed layers comprising a layer of cellulosic fibres and a layer of synthetic thermoplastic polymeric fibrils, either layer being superimposed on the other, reducing the water content of the sheet to from 30-80% by wt. by suction and/or compression, drying the sheet to a moisture content of less than 0.5%, and heating the sheet under pressure at a temperature greater than the softening temperature of the thermoplastic polymer. The latter may be a polyolefin, e.g. a low or high density polyethylene, isotactic polypropylene, or ethylene/propylene copolymer with a predominant content of propylene, a polyamide e.g. nylon 6, a vinyl polymer e.g. polyvinyl chloride, polyvinyl acetate, polyacrylonitrile, or a polyoxymethylene. Mixtures of the same polymeric fibrils but with different thermoplastic characteristics, or of different polymeric fibrils, may be used provided that they are compatible with each other and have sufficiently close softening temperatures. Cellulosic fibres may be present in the layer of thermoplastic polymeric fibrils. The cellulosic layer of the paper may be calendered, coated and/or sized. Conventional additives, e.g. dyestuffs, pigments, fillers, dispersants, anti-mildew agents, and other fibres, e.g. rayon, cellulose acetate, nylon, or polyvinyl alcohol fibres, may be added to the aqueous fibrous dispersion from which each layer is formed. Preferably, the thermoplastic polymeric fibrils are coated with a polyvinyl alcohol/aliphatic aldehyde condensate. A laminate comprising a layer of thermoplastic polymer in the form of a continuous film sandwiched between two or more sheets of paper or cardboard may be made by the process. Apparatus. The preparation of a two-layer sheet, see Fig. 1, may be carried out using cylinder machines 1, 2 for cellulosic fibrous stock and thermoplastic fibrous stock respectively. A layer of thermoplastics fibres is superimposed on a layer of cellulosic fibres and the resulting sheet is conveyed by felt 10 past suction boxes 3 and press rolls 4. The still wet sheet is conveyed over drying cylinders 5, and then through glazing unit 6, and cooling rolls 7, before being taken-up on reel 8. The preparation of a cellulosic/thermoplastic material/cellulosic-laminated sheet, (Fig. 2, not shown) may be carried out as described above, except that two cylinder machines are used for the cellulosic fibrous stock, and a Fourdrinier for the thermoplastic fibrous stock, the latter machine being located between the two cylinder machines.

Title: Process for Making Graphitic Neutron Absorbing Articles
Inventor: CLEDAT JEAN
IPC: G21F1/06
Filed: 1968-03-13
Abstract: 1,169,322. Neutron absorbing materials. COMMISSARIAT A L'ENERGIE ATOMIQUE. 13 March, 1968 [24 March, 1967], No. 12132/68. Heading G6R. A neutron absorbing material consists of a compact body of artificial graphite powder bound by coke resulting from the carbonization of pitch or coal tar, with a neutron absorbing compound selected from boron nitride, dehydrated borocalcite and oxides of rare earth metals dispersed throughout in powder form. The graphite powder can be made up of two parts, one having a particle size less than 80Á and the other a particle size within the range 0À5 to 1À5 mm. In order to facilitate subsequent extrusion, up to 10% by wt. of the graphite-neutron absorbing compound mixture may be replaced by lamp-black. The neutron absorbing compound has a particle size less than 80Á and the mixing operation is carried out in a heating mixer at a temperature between 100 and 150 C. in order to eliminate the water content. Once the compound has been completely dispersed, a binder such as coal-tar, pitch or petroleum asphalt in a proportion between 15% and 30% by wt. of the dry mixture is added to form a paste which is extruded or press-formed to the desired shape. It is then transferred to a furnace in which it is baked without exposure to air in order to carbonize the binder, preferably beneath a layer of coke powder, at a temperature below that at which reduction of the neutron absorbing compound by carbon takes place at an appreciable rate. This temperature should be in the range 900 to 1700 C., preferably between 1000 and 1200 C., but below 1150 C. in the case of borocalcite. The use of boron nitride enables a boron content as high as 15% by wt. to be attained whereas the use of the lower cost borocalcite does not result in a boron content greater than 6% by wt. Rare earth oxides permit the fabrication of parts which can be irradiated to very high doses since they do not give rise to helium evolution by the (n, α) reaction. The material may be used as a shield against fast neutrons or as a fast reactor control member. In the latter application, it is advantageous to employ oxides containing a high proportion of the rare earths which have a particularly high neutron capture cross-section, especially gadolinium oxide.

Title: Process for preparing polyesters from lactones
IPC: C08G63/82
Filed: 1957-04-15
Abstract: In the manufacture of a polyester by reacting a lactone having at least six carbon atoms in the ring with an organic compound containing at least one alcholic hydroxyl or a primary or secondary amino group attached directly to carbon, the reaction is effected in presence of 0,001- 1% of a catalyst which is an organo tin compound or a lead or manganese salt of an organic carboxylic acid.  The lactones and the initiators (which may be monomeric or polymeric) are as specified in Specification 859,642.  The organo tin compound preferably has the formula:  <FORM:0859639/IV(a)/1> and <FORM:0859639/IV(a)/2> where X is an alkyl, aryl, aralkyl or aryloxy radical and X1 is in alkyl aryl, aralkyl, acyloxy, halogen or hydroxyl radical. For example tetraphenyl tin, tetraoctyl tin, diphenyl tin dilaurate, tri-n-butyltin hydroxide, tri-n-butyltin acetate, dimethyltin oxide, di-n-butyltin dichloride and diocytltin dichloride.  Specified lead and manganese salts are lead acetate, manganese acetate, lead 2-ethylhexoate and lead benzoate. Polymerization of the lactone is preferably effected at 50 DEG -300 DEG C. in the absence of oxygen until the refractive index of the polyester becomes constant and at the end of the reaction unreacted monomer may be removed by applying a vacuum.  The polyesters generally have a molecular weight of 500-12,000.  They may be used as plasticizers, e.g. for vinyl chloride-vinyl acetate resins, especially if the terminal hydroxyl groups are acylated or may be reacted with isocyanates to form polyurethanes.  Examples describe the polymerization of epsilon-caprolactone, alkyl, dialkyl and trialkyl caprolactones, zeta-enantholactone and various mixtures thereof.  Specifications 859,640, 859,641, 859,643, 859,644 and 859,645 also are referred to.
