Abstract: 1462342 1,4-Butanediol E I DU PONT DE NEMOURS & CO 31 July 1975 [31 July 1974] 32119/75 Heading C2C 1,4-Butanediol is produced by hydrolysing and hydrogenating a mixture of 2-(3<SP>1</SP>-propanal)- 5 - methyl - 1,3 - dioxane and 2 - (21 - propanal) - 5 - methyl - 1,3 - dioxane in the presence of a hydrogenation catalyst, said mixture being prepared by hydroformylating 2- vinyl-5-methyl-1,3-dioxane prepared by reacting 2-methyl-1,3-propanediol with acrolein. 2-Methyl-1,3-propanediol is also obtained as product with the butanediol; the two diols may be separated by distillation and the 2-methyl- 1,3-propanediol so obtained used for the reaction with acrolein. The hydrolysis/hydrogenation may be carried out at 100-5000 p.s.i.g., 30-130 C., using as catalyst palladium or charcoal. A rhodium carbonyl complex and an alkyl or phenyl phosphite may be used as catalyst for the hydroformylation. In comparison examples, other vinyl derivatives are similarly hydroformylated to a mixture of the corresponding (3<SP>1</SP>-propenal) and (2<SP>1</SP>- propenal) derivatives, and the mixtures hydrolysed and hydrogenated to give diols, in addition to I and II, as follows: 2-vinyl-5,5-dimethyl- 1,3-dioxane gives 2,2<SP>1</SP>-dimethyl-1,3-propanediol; 2 - vinyl - 4,4,6 - trimethyl - 1,3 - dioxane gives 2 - methyl - 2,4 - pentanediol; 2 - vinyl- 4 - methyl - 1,3 - dioxane gives 1,3 - butanediol; 2 - vinyl - 4 - methyl - 1,3 - dioxolane gives 1,2-propanediol.
Patent GB-321709-A (GB)
Abstract: 321,709. Hemmingsen, T. V. Aug. 16, 1928. Reversing.-In chain gearing between the engine crank-shaft and the ignition dynamo shaft, the cam shaft, or the fuel-pump shaft, adjustable idlers engaging the chain runs are employed for changing the phase relations between the shafts geared together, the idlers being controlled by hand or automatically by a reversing member of the engine. The crank-shaft 1 and cam shaft 2, Fig. 1, are connected by a chain 5 upon which bear idlers 7, 12 carried on arms 6, 11 pivoted about the shafts or about other axes.

Title: Improvements in or relating to adhesive polyester compositions
Inventor: HARDY ALAN
IPC: C08G63/60
Filed: 1963-08-15
Abstract: A thermoplastic adhesive composition comprises a polyester derived from 40 mols of isophthalic acid and 0.5-7 mols of a saturated aliphatic dibasic acid containing 6-10 carbon atoms, an amount sufficient to provide the composition with adequate creep characteristics, but less than that which will produce gelling, of a compound containing at least three hydroxyl or carboxyl groups, and an amount of a glycol containing 2-4 carbon atoms providing in total sufficient OH groups to react with all COOH groups present. Preferred compositions contain, per 40 mols of isophthalic acid, 0.5-7 mols of aliphatic dibasic acid and 0.5-2 mols of the polyfunctional compound.  The aliphatic dibasic acid may be azelaic or sebacic acid, and the preferred glycol is 1,4-butylene glycol. Suitable polyfunctional compounds are trimellitic anhydride, trimesic acid, hydroxymalonic acid, malic acid, tricarballylic acid, trimethylol propane, glycerol, 1,2,6-hexane-triol and pentaerythritol. In Examples the polyester is prepared from isophthalic acid, dibutyl sebacate, 1:4-butane-diol, and trimellitic anhydride or 1:2:6-hexane-triol.ALSO:Sole units are bonded to lasted shoe uppers using a thermoplastic adhesive composition comprising a copolyester formed from isophthalic acid, an aliphatic saturated C6-10 dicarboxylic acid, a compound containing at least 3 carboxyl and/or hydroxyl groups, and a C2-4 glycol, the two first being in a molar ratio of 40 : 0.5-7, the third sufficient to give adequate creep characteristics but insufficient to cause the composition to gell, and the glycol sufficient to ensure the presence of hydroxyl groups sufficient to react with all the carboxyl groups.  The composition need be applied to one only of the surfaces to be joined, e.g. in molten form to a resin rubber sole unit.  In Examples the polyester is prepared from isophthalic acid, dibutyl sebacate, 1 : 4-butane-diol, and trimellitic anhydride or 1 : 2 : 6-hexane-triol.

Filed: 1970-07-03
Abstract: 1302394 Seismic energy generators WESTERN GEOPHYSICAL CO OF AMERICA 3 July 1970 [23 July 1969] 32483/70 Heading H4D Acoustic impulses are produced underwater by expanding a sealed chamber relatively slowly, then decreasing the chamber volume sufficiently rapidly to produce cavitation in the water. In the embodiment of Figs. 1 and 2 the chamber comprises a flexible membrane 16 clamped at its edge to a rigid metal plate 18. A charge of compressed air is passed through valve 28 to inflate the chamber, which is "fired" by opening valves 46, 48, 50 to exhaust the air into vacuum reservoirs 32, 34, 36. Ambient hydrostatic pressure forces the membrane against plate 18 to generate an impulse. If the membrane is resilient (e.g. of rubber), tensional forces resulting from stretching of the membrane prior to "firing" will assist in collapsing the chamber sufficiently rapidly to cause cavitation at the membrane. Air pressure and vacuum conduits 26, 60 are connected to a pumping system aboard a towing-ship. In an alternative embodiment (Figs. 5 and 6, not shown) plate 18 is replaced by a plate of inverted saucer shape, surmounted by a doughnut-shaped vacuum reservoir.
