Patent GB-855003-A (GB)
Title: Manufacture of norbornylene
IPC: C07C2/50
Filed: 1959-06-02
Abstract: Norbornylene (bicyclo- (2 : 2 : 1)-2-heptene) or its methyl derivative is prepared by reacting ethylene with a mixture of cyclopentadiene or methylcyclopentadiene and its dimer, the temperature being controlled by the relative proportions of monomer and dimer, the heat loss from the endothermic cracking of the dimer and the heat gain from the exothermic reaction of monomer and ethylene cancelling one another out.  Liquid phase reaction with dissolved ethylene is preferred, employing a temperature of 150-250 DEG C. and a pressure of 500-10,000 p.s.i.g. Norbornylene is recovered from the product using two fractionating towers, the first tower yielding cyclodiene monomer contaminated with norbornylene as an overhead (which overhead may be returned to the reaction), norbornylene contaminated with monomer as a side stream and cyclodiene dimer as bottoms.  The side stream is separated from cyclodiene monomer in the second tower.  Commercial mixtures of cyclo- and methylcyclo-pentadienes may be used; methylnorbornylene separated from norbornylene may be recovered as product or cracked to obtain pure methylcyclopentadiene.

Patent GB-147118-A (GB)
Title: Improved manufacture of butyric aldehyde and butyl alcohol from crotonic aldehyde
IPC: C07C45/62
Filed: 1920-07-07
Abstract: The catalytic hydrogenation of crotonic aldehyde to butyric aldehyde and butyl alcohol is effected in the presence of water or steam, preferably that separated from the hydrogenated product. It is preferred to employ an excess of hydrogen in order to remove from the reaction chamber products arising from the decomposition of the crotonic aldehyde which occurs simultaneously with the hydrogenation; and the surplus hydrogen may be returned to the process after the recovery of the propylene contained therein.  In place of pure crotonic aldehyde there may be used in this process the product of decomposition of alcohol, after the removal of the acetaldehyde.  In carrying out the process the hydrogen and reacting materials may be passed in a cycle through the reaction chamber, or the reaction may be carried out in a closed pressure apparatus.ALSO:Propylene is recovered from the surplus hydrogen employed in the catalytic hydrogenation of crotonic aldehyde to butyric aldehyde and butyl alcohol.

Title: Method of attaching a cup-shaped support base to a convex bottom of an article
IPC: B29C65/56
Filed: 1978-05-15
Abstract: A method and apparatus are disclosed for mounting a cup-shaped support base onto a convex bottom of a container. The apparatus includes adjacent wheels mounted for rotation about angularly related, non-parallel axes, so that the wheels are closer to one another in one circumferential region than in any other such region. In the method, a container is retained on the periphery of one wheel for displacement along a partial-circumferential path. A cup-shaped support base is retained on a second wheel in alignment with a convex bottom on the container. As the wheels rotate, the base and container are displaced in unison to said one circumferential region, with the base progressively moving closer to the convex bottom for their telescopic assembly. An abutment surface, which may be on a third wheel, engages an opposed end on the container while the container is displaced during the final portions of said partial-circumferential path, in order to resist axial displacement of the container as the base is assembled to its convex bottom.
