Patent GB-879624-A (GB)
Title: Production of conjugated diolefines
Inventor: FREUD ANTON WALTER
IPC: C07C1/247
Filed: 1959-08-06
Abstract: Isoprene is obtained by the vapour phase catalytic decomposition of 4,4-dimethyl-1,3-dioxane in the presence of added isobutene; the formation of by-product isobutene is thus suppressed.  The catalyst is preferably a phosphate of a Group III B element, e.g. boron, and the reaction is effected at 200-450 DEG C. at a space velocity of 0.1-100 liquid volumes of the dioxane per volume of catalyst per hour in the presence of steam. Isobutene may form 1-50% by volume of the mixture, and may be obtained by recycling isobutene separated from the decomposition product, further isobutene being added if desired. Alternatively the process is coupled with the formation of the dioxane from isobutene and formaldehyde, the initial isobutene being fed to the dioxane decomposition, separated from the product and recycled to the dioxane production step.  The Provisional Specification refers generally to the catalytic decomposition of 1,3-dioxanes to diolefins in the presence of the by-product olefin.

Such mixtures have a relative permittivity of 4 or more, and a considerable reduction in the length of the monopole results. In a second embodiment a conductive ring is positioned between the end of the outer conductor of thecable and the dielectric material cylinder, the ground plate being omitted (Fig. 2, not shown). In a third embodiment, a conductive ring is positioned about the dielectric material cylinder and is connected to the outer conductor of the cable, the ground plate again being omitted (Fig. 3, not shown). Another embodiment features a dipole, which is fed by a two-wire balanced line, and is surrounded by dielectric material (Fig. 7, not shown).

Title: Method of and apparatus for finding the optimim pasting speed for replacing webroll sin web-fed rotary printing presses
IPC: B65H19/16
Filed: 1977-06-29
Abstract: The device has a radiation transmitter (7) and a radiation receiver (9) which are allocated to at least one edge (8) of a paper web (5). The electromagnetic radiation emerging from the transmitter is directed onto a sensitive surface (11) of the radiation receiver, the paper web intersecting a ray path (10) within the sensitive surface of the receiver. A control device influencing the drive speed of the web-fed printing machine is connected downstream of the receiver. Before commencement of a roll-changing operation, the frequency and/or amplitude of a flutter movement of the expiring paper web are measured. The measured values are then fed to the aforementioned control device. The optimum machine speed is thus predetermined in the event of a paper roll exchange. <IMAGE>

[Class 2 (iii)] [Also in Group VIII] A surface of a formaldehyde resin, such as urea-, phenol-, cresol-, aniline- or melamineformaldehyde, or mixtures thereof, is united to a similar surface or to a surface of cellulosic material such as wood by applying to at least one of the surfaces an adhesive or cement comprising an aromatic amine-formaldehyde condensation product incorporated with an initial condensation product of phenol and formaldehyde in water, alcohol or other volatile solvent, applying the two surfaces to one another and hardening the adhesive by heat and pressure. The phenol-formaldehyde product may be obtained by boiling, under reflex, a mixture of 1 mol. phenol with 1.3-1.5 mols. formaldehyde in the presence of an acid or alkaline catalyst. As aminb-formaldehyde condensation product there is preferably employed an aniline-formaldehyde condensation product obtained by reacting about 1 mol. aniline with 1-5 mols. formaldehyde in the presence of 0.8-1 mol. of hydrochloric acid and sufficient cold water to keep the temperature of reaction from rising above 40C., the solution obtained being allowed to stand for about 1 hour and the resin precipitated by addition of alkali, washed, dried and ground. Preferably the adhesive comprises 1-2 parts of the aniline-formaldehyde resin with 2-1 parts of the phenol-formaldehyde condensation product containing about 50 per cent. resin; a small proportion of a wetting agent, e.g. 0.1-0.3 per cent. of ammonium sulphoricinoleate, calculated on the total resin, may be added to assist spreading. After application of the adhesive, the surfaces are united under a pressure of 200 lbs. sq. in. at a temperature of about 140C. until the adhesive has set or hardened. For large surfaces, the anilineformaldehyde resin is mixed with an acetone solution of the phenol-formaldehyde resin and the mixture applied to the surface or surfaces and allowed to dry before the application of heat and pressure. The synthetic resins to be united may be fully or partly cured 'and may contain fillers, e.g. wood flour or slate dust, or reinforcements, e.g. asbestos or textiles.
