Title: Process for the preparation of Diesters of 1,2-Dicarboxylic Acids
Inventor: ZEEUW ABRAHAM JOHANNES VAN DER
IPC: C08K5/12

Abstract: 1,191,380. Diesters of dicarboxylic acids; alcohols. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 28 Oct., 1968, No. 50936/68. Heading C2C. [Also in Division C3] Mixed diesters of a 1,2-dicarboxylic acid, together with the anhydride of the acid, are obtained by heating a mixture of monoesters of the acid to a temperature of at least 100‹ C. in the absence of alcohols and while removing the water formed, preferably by azeotropic distillation. The preferred starting materials are mixtures of monoesters of the acids with aliphatic alcohols of 6-11 carbon atoms, and such mixtures may be prepared by mixing appropriate monoesters of the acid or by monoesterifying the acid with an appropriate mixture of alcohols. Such a mixture may be obtained by reacting an olefine or olefine mixture with carbon monoxide and hydrogen in the presence of a catalyst complex comprising (a) a transition metal of atomic number between 23 and 85, preferably cobalt, and (b) a biphyllic ligand containing trivalent phosphorus, arsenic or antimony (see Specification 988,943). The diester-forming reaction may be effected in the presence of catalysts, among which zinc chloride and tetrabutyl orthotitanate are specified. The acid anhydride also produced in the process may be separated by filtration or extraction or it may be worked up by adding a mixture of alcohols to the reaction product to convert part or all of the anhydride into monoesters, which may then be treated in accordance with the invention. In Example 1, monoesters of phthalic acid are prepared by heating phthalic anhydride with an alcohol mixture prepared by reacting a mixture of olefines of 6-8 carbon atoms with carbon monoxide and hydrogen in the presence of a catalyst comprising dicobalt octacarbonyl and tri-n-butylphosphine, the mixture being then fractionated and the fractions being heated to 175‹ C. in the presence of xylene. The products of this example are useful as plasticizers for polyvinyl chloride (see Division C3). Other specified 1,2- dicarboxylic acids, the mono esters of which may be treated, are succinic and maleic acids.

Abstract: 1330416 Stamping F B HATEBUR AG 3 Nov 1971 [3 Nov 1970] 51131/71 Heading B3Q The stamp bearer on a pivot in a stamping press is horizontally and vertically adjustable by means of an adjustable guide, both the pivot and guide engaging vertical grooves in the press slide. In Fig. 1, after releasing clamping bolts which pass through holes 3, the bearer 1 is turned about a pivot 33 by screws 23, 24 which engage screwthreads 21, 22 in the bearer and bear against a guide pin 34. The latter engages a slot 12 in the bearer and is adjustable vertically, by a screw 18, in a groove 17 in the slide 2 so as to raise or lower the bearer. The pivot pin 33 engages a vertical groove 10 in the slide to accommodate its vertical displacements as the bearer is turned about the pin by the screws 23, 24. The pivot pin 33 and guide pin 34 may be replaced respectively, by pin and slide block assemblies 7, 9 and 13, 15. A curved slot 12 may be used, Fig. 7 (not shown), if it is desired to effect horizontal displacement of the bearer axis 25 without a vertical component to be cancelled by the screw 18. In another construction, Fig. 10, the slot 28 for the bearer is formed in a bush 27, which swivels during adjustment of the bearer by screws passing through clearance holes in the bush to engage the pin 32. The pivot may be located at the top of the slide and the adjustment device at the bottom.

The carrier 6 may have greater stiffness than the lip 5 and may comprise a fibre-reinforced material, the lip 5 being free of fibre reinforcement. In one example (Fig. 3a) the carrier material is injected through one sprue 8 and the lip material through another sprue 9, a sleeve shaped partition 7 being removed after injection. Both materials may be injected simultaneously, or one shortly after the other. The partition may be removed before the second material is injected. In another example (not shown) a fibre-reinforced material is injected through a single sprue which contains baffles which produce a partial separation of the components of the material, so that the sealing lip is substantially free of reinforcing fibres. Glass, textile or metal fibres may be used.

Abstract: 1,028,609. Gear pumps. NEW YORK AIR BRAKE CO. Dec. 18, 1964 [April 2, 1964], No. 51535/64. Heading F1F. A gear pump comprising a three-part casing 11, 12, 13, Fig. 1 (not shown), housing intermeshing gears 16, 17 mounted on driven and idler shafts 14, 15 respectively and wear-plates 21 adjacent the side faces of the gears, includes openings 22, Fig. 2 (not shown) through the wear-plates through which the shafts project formed with counterbores 23 opening from the gear-engaging faces. Each counterbore receives an annular flanged seal plate 24 having a sealing face 26 on its flange 25 adjacent its associated gear with its outer periphery lying entirely within the roots of the gear teeth. Behind the flange 25 an O-ring seal 27 and a back-up plate 28 are fitted. Leakage fluid passing between the flange 25 and counterbore 23 presses the seal 27 sealingly into the counterbore and the trapped fluid urges the seal plate 24 into sealing engagement with its associated gear. Any fluid that should leak past the face 26 is collected and drained off at 20. Instead of the O-ring seal 27 and back-up plate 28, a seal ring 27<SP>1</SP>, Fig. 3 (not shown) having a V-shaped groove 29 may be fitted. Leakage fluid then acts on the two faces of the V to seal the ring in the counterbore and as before the pressure of the trapped fluid urges the seal plate 24 sealingly against its associated gear. In another embodiment, a spring is fitted in the counterbore 23 to urge the seal plate into contact with the gear. A seal ring is then fitted in a groove formed in the wear-plate opening to seal against the outer periphery of the annular seal plate.

[Also in Division H1] In bonding a refractory metal member to a second metal member a coating of iron is attached to the refractory metal member, the coating is engaged with the second metal member and heat and pressure are applied to the assembly to melt the iron and cause the interdiffusion of the iron into the members with the formation of a diffusion bond. The metal core 19 of a directly heated emissive material carrying filament of an electron discharge device is fixed to the connector 27 affixed to a conductor sealed into the envelope of the device. The core is of refractory metal e.g. tungsten, molybdenum, columbium, platinum, ruthenium or alloys thereof and the connector is e.g. of nickel, steel or alloys thereof and the bonding metal in the form of a sheath 29 on the core is of iron.
