Abstract: A process for the preparation of camphene by the rearrangement of .alpha.-pinene in the presence of a titanium oxide hydrate catalyst under the action of heat, wherein .alpha.-pinene is refluxed until the content of .alpha.-pinene in the reaction mixture is still at least 3% by weight, and the rearrangement is then brought to completion in a secondary reaction at a temperature below 160°C. By carrying out the process in this way - refluxing to a relatively high residual content of .alpha.-pinene and performing a secondary reaction at a lower temperature - the formation of polymeric by-products is reduced. This process moreover increases the yield of camphene in that recycled tricyclene, concentrated in the distillation of the crude product, is partially rearranged to camphene or the formation of more tricyclene is reduced.

Title: Winder with elevated spool support rail
Inventor: BAGNATO LUIGI J
IPC: B65H18/08
Filed: 1995-08-11
Granted: 2001-07-31
Abstract: A winder in a papermaking machine has a frame (40) with horizontal rails (42) which are positioned above the apex of the surface of a rotatable reel support drum (34), which is fixedly mounted. As a relatively large diameter wound paper web reel, or jumbo, is formed on a spool riding on the rails, the surface of the jumbo remains tangent to the top of the support drum as the spool moves from a position vertically over the reel drum to a position laterally displaced horizontally along the rail. Centerwind drivel(s) (36, 38) control spool torque.      As the jumbo increases in size, it is moved linearly away from the initial position, while maintaining the paper web reel rotatively supported and in a nipping engagement with the support drum. Nip pressure between the support drum and the jumbo is controlled by the force of gravity and the horizontal positioning of the jumbo along the rails. The positioning of the jumbo along the rail may be controlled by a conventional pneumatic or hydraulic cylinder, or a screw mechanism. An alternative embodiment winder utilizes primary (121) and secondary arms (123) to position the jumbo and its spool along the reel rails.

Abstract: L'invention concerne un procédé et un dispositif pour enregistrer des données dans une carte optique, qui facilitent la distinction entre une zone non enregistrée et une zone enregistrée de la carte optique et qui empêchent la superposition d'écriture. Des alvéoles sont formées de sorte que les données à enregistrer sur la carte optique soient enregistrées de la même manière que dans le système de modulation de fréquence modifiée et d'enregistrement avec retour à zéro (MFM-RZ). Les données enregistrées dans le système de modulation NRZI-RZ sont reproduites puis enregistrées dans ledit système de modulation MFM-RZ. Ce procédé consiste à former des alvéoles au moins tous les deux intervalles d'enregistrement ou moins dans la zone enregistrée de la carte optique, ce qui permet de distinguer la zone enregistrée de ladite carte de la zone non enregistrée selon que des alvéoles d'enregistrement sont présentes ou non et d'empêcher ainsi la superposition d'écriture.
