This Section contains abstracts (without graphics) of recently issued United States patents
and pzblished patent applications filed from over 35 countries under the Patent Cooperation Treaty. This informatloa was obtained from recent additicns to the Pergamon PATSEARCH” oc!ice database in accordance with imerest profiles developed by the Editors. Further information about Pergamon PATSEARCHW can be obtained from Pergdmor. InfoLine Inc., 1340 Old Chain Bridge Road, McLean, Virginia 22101 U.S.A. Copies of completepatents announced in this Section are available from Pergamon InfeLine Inc. for $8 per copy. Payment with order is required. Orders outside North America add $2 for air postage. Order bji patent number for Pergamon InfoLine only.
proviced for the top of the vessel. A cyiicdrkal fiber is disposed in surrounding relationship tc the heating unit.
Raymon Le Diouron, Voiron, France assigned to L’Air Eiquide Societe Anonyme pour I’Etude et I’Exploitation des Procedes Georges Claude The cable C to be stripped is wound with nontouching coils and crossed layers of cable onto a drum 6 having a perforated COR 10 rotativejy mounted in a thermally insulated container 1. By injecting into the container liquid nitrogen under the control of a temperature sensor and by circulating the gases contained in the container through the cor.e of the drum and the cable coils, the whole of the cable is cooled down to a temperature at which the plastics coating and, as the case may be, the outer steel sheath of the cable become brittle. The cable is then unwound and, when it has left the container, it is subjected to vario~3s mechanical stresses. The stripped cable is finally wound onto a take-up reel 3. Appiication in the recovery of scrap in the manufacture ofpower cables of large diameter and recovery of used electric cables.
To improve the separation of a produced oilwater emulsion containing a surfactant, the emuision parameters of temperature and salinity are brought within certain critical limk The emulsion will separate into an injectabie brinejsurfactant phase and a pine&e qua!ity crude oil phase. The operable sahnity range is from about 70% to about 130% of the reservoir salinity, and the operable temperature range is from about 75 degrees F. lower to abou? 75 degrees F. higher than the temperature of the reservoir from which the emulsion was produced,

A fluid recovery system for removing water and solid contaminants from a fluid such a lubricant oil, coolant, and lubricating oils and the like for ma~~~factnr~ng operations is disclosed. A cyhndrical vacuum vessel is provided with a centrally disposed cylindrical heating unit and a heat exchanger ceil surrounding the heatmg unit, within the confk~es of the vacuum vessel. A water condensation trapping cover seal arrangement is
A process is disclosed for recovering cobalt in a relatively pure km from an impure cobalt bearing material. The process involves digesting the material in ~~dr~c~l~r~c acid to form a solution essentially all of the cobalt and some impurities and ~~s~l~~le marerial c~~ta~~i~g the remainder of the impurities, separating the solution from the insolubles, adding an oxalate producing c~rn~~~~d in an amour?: suikiea~ 25
