Title: Process for treating cobalt catalyst in oxidation mixtures of hydrocarbons to dibasic acids
Inventor: VASSILIOU EUSTATHIOS
IPC: C08G73/10
Filed: 1999-01-14
Abstract: This invention relates to methods and reactor devices for controlling the oxidation of hydrocarbons to dibasis acids, in the presence of a cobalt catalyst and a monobasic acid, such as acetic acid, by treating the catalyst from the reaction mixture, outside the oxidation zone, after the oxidation has taken place at least partially. In one preferred embodiment, the catalyst is reduced to contain, preferably predominantly and more preferably substantially, cobalt ions in valence II, and at least partially precipitated by de-watering and/or thermal treatment. In a different preferred embodiment, the catalyst in the reaction mixture is first oxidized or maintained, preferably predominantly and more preferably substantially, at valence III, the reaction mixture is de-watered, the catalyst is reduced, preferably predominantly and more preferably substantially, to valence II, causing precipitation either spontaneously at a predetermined temperature or after further thermal treatment. The precipitated catalyst is preferably recycled directly or indirectly.

Title: Method and compositions for treatment of cancers
Inventor: LENTZ M RIGDON
IPC: A61K41/00
Filed: 1999-05-21
Abstract: A method to treat cancer uses ultrapheresis, refined to remove compounds of less than 120,000 daltons molecular weight, followed by administration of replacement fluid, to stimulate the patient's immune system to attack solid tumors. In the preferred embodiment, the patient is ultrapheresed using a capillary tube ultrafilter having a pore size of 0.02 to 0.05 microns, with a molecular weight cutoff of 120,000 daltons, sufficient to filter one blood volume. The preferred replacement fluid is ultrapheresed normal plasma. The patient is preferably treated daily for three weeks, diagnostic tests conducted to verify that there has been shrinkage of the tumors, then the treatment regime is repeated. The treatment is preferably combined with an alternative therapy, for example, treatment with an anti-angiogenic compound, one or more cytokines such as TNF, gamma interferon, or IL-2, or a procoagulant compound. The treatment increases endogenous, local levels of cytokines, such as TNF. This provides a basis for an improved effect when combined with any treatment that enhances cytokine activity against the tumors, for example, treatments using alkylating agents, doxyrubicin, carboplatinum, cisplatinum, and taxol. Alternatively, the ultrapheresis treatment can be combined with local chemotherapy, systemic chemotherapy, and/or radiation.

Title: Adhesive labels and manufacture thereof
Inventor: DENNY ANDREW
IPC: G09F3/02
Filed: 1999-09-06
Abstract: The adhesive labels are manufactured by cutting windows in the upper layer of a support web (2) through to a lower silicon coated material. Folded leaflets (15) are then adhered by lines of adhesive (11, 12, 13) to the support web (2) and the combination is die-cut to form individual adhesive labels with part of the die-cut folded leaflet extending beyond an edge of a base label formed from the window in the support web.
