Abstract: ABSTRACT OF THE DISCLOSURE         Saturated organic compounds containing a hydrogen atom bound to a tertiary carbon atom may be electrophilically fluorinated by reacti?n with an electrophilic fluorinating agent such as molecular fluorine or trifluoromethyl hypofluorite under conditions whereby the formation of free fluorine radicals is suppressed, e.g. by the presence of a free radical inhibitor such as oxygen or nitrobenzene, the reactants being substantially homogeneously dispersed in a liquid medium, e.g.  A solvent medium such as fluorotrichloro-methane or chloroform/fluorotrichloromethane. so that the said hydrogen atom is electrophilically replaced by a fluorine atom.  The fluoroination is highly selective and, in the case of complex substrates such as saturated steroids which contain a ?umber of tertiary - 1a -C-H bonds, may be substantially completely confined to replacement of the hydrogen atom at the tertiary carbon atom which has the highest electron density about the C-H bond.  The electron density and thus the direction of the fluorination may be controlled by appropriate selection  of substituent groupings in the substrate molecule.         Novel 14.alpha.-fluorosteroids are also disclosed, including compounds having valuable androgenic or progestational activity and  useful synthetic inter-mediates.     - 1b -

Abstract: ABSTRACT OF THE DISCLOSURE      An air system for the collection and utilization of solar energy. Tubular solar collectors are made with a transparent glass tube having a cylindrical outer wall, spaced and sealed at one end to a cylindrical absorber tube that has a solar energy absorbing surface. The sealed space between the glass tube and absorber tube is evacuated. Several of the collectors are connected into a manifold split into separate chambers by a dividing wall. A divider strip is fastened as a continuation of the dividing wall of the manifold by a novel detachable fastener means. The divider strip fists snugly inside the absorber tube of each collector dividing it in half and spanning nearly the entire length thereof. Pressurized air is supplied into the one high pressure chamber of the manifold and is connected into the one half section of the absorber of each collector at the open end connection, guided by the dividing strip the length of the absorber tube the other half of the manifold which is at lower pressure. The reverse flow of air the length of the absorber tube exchanges solar heat absorbed on the solar energy absorbing surface. Heated air in the lower pressure chamber is conveyed to a heat exchange storage element and/or load device operable for heating or cooling purposes.

Abstract: POSITIVE PROCESS USING A LOW COATING    WEIGHT SILVER HALIDE ELEMENT                ABSTRACT OF THE DISCLOSURE A novel process for obtaining camera speed direct positive images is described.  This process utilizes an element comprising a support, at least one layer con-taining a colorant (e.g. colloidal silver) and at least one layer of photosensitive silver halide.  After an imagewise exposure of the silver halide layer allowed by development of the image in the presence of at least one compound capable of producing sulfide ions (e.g. thiourea), a direct positive image is produced in the colorant layer by bleaching. The bleaching step removes the silver image generated in the silver halide layer and the colorant layer associated therewith.  Those regions of the colorant layer corresponding to the nonimage areas of the silver halide layer are insoluble in the bleach.  After a conventional fix-ing step, a high quality direct positive image remains in the colorant layer.  Since this image results from an exposure of a silver halide layer, the element is of camera speed.  A considerable reduction in silver halide coating weight is also possible.

Abstract: COMPRESSED REFRESH BUFFER         ABSTRACT Data compression is effected in the refresh loop of a transient video display.  The digital image is divided into equal areas and mapped in a bit map store.  If an area contains one bits it is represented by a one in the bit map store, otherwise it is represented by a zero. A refresh buffer store contains only those areas including one bits. The buffer and bit map stores are operated synchronously and zeroes are forced in the data stream to the video display when zero is detected in the bit map store.  Extension of the scheme to provide for colour displays is described.

Abstract: ABSTRACT OF THE DISCLOSURE         In order to replace the electricity required to drive the com-pressors of the apparatus, the nitrogen-producing means is supplied with a flow of a synthesis gas mixture from the synthesis circuit of the synthesizing plant.  This gas mixture is burned with compressed air to form a mixture of water vapor and nitrogen.  The water vapor is then condensed in a condensor and separated out for entry into an exchange tower of the monothermal isotope exchanger.  The separated nitrogen is supplied together with hydrogen to form the synthesis gas mixture for the synthesizing plant.  In addition, a steam circuit is connected with the condensor and has a steam turbine which produces work to drive the compressor for the air and the compressors used to compress the synthesis gas mixture.  Water is enriched with deuterium in an isotropic process.  A portion of the enriched water is stored during the colder half of the year to be used during the warmer half when such water is electrolytically dissociated to form hydrogen which forms part of the synthesis gas.
